The comfortable L-shaped leather couch was unusually deep with a wide seat and a firm cushioned back that supported my neck perfectly. It had taken me weeks to find this couch. I must have plonked into hundreds before finding this particular gem and I was very proud of it. It was my 'bed-away-from-bed'. Since my life seemed to revolve around the custom-built quad-core, liquid-cooled, over-clocked computer in my study and the Samsung flat-panel 65" LED TV in front of me, a supremely comfortable couch was a must.

With legs stretched out and ankles crossed, I slouched and relaxed, wiggling my toes inside socks, sneakers kicked off to the floor, mind drifting. Through floor-to-ceiling glass wall I studied a familiar vista. Downtown Toronto in the late afternoon summer was pretty, the CN Tower a tall spire rising above the city, Lake Ontario calm and blue stretching out before me, and in the hazy distance across the lake, the faint outline of Buffalo. Toronto Island was a lush green and, to my left, the startling Manulife building, its gold-tinted glass cladding making it look like a massive gold ingot standing on end, shimmering and glowing from sun striking it at the perfect angle. Below me, the harbour was busy with late afternoon sightseeing cruise-boats plying their trade at a leisurely pace. To the right I saw the dome of Ontario Place, and beyond, the marina filled with weekend boats; small power boats, large luxury cruisers, and sleek sail boats all clean, neat, and locked up until the approaching weekend, waiting for their owners to descend for their symbolic escape from civilization.

Despite Toronto being a big metropolis, it was remarkably green; a carpet of trees stretching as far as the eye could see with occasional tall office and apartment buildings rising in clusters. Toronto was the greenest city I'd ever seen.

Behind me I heard a laugh amid the noise of unpacking. It made me smile. It was good to hear it. Memories of my childhood came flooding back; Switzerland, nine years old and exploring the drainage tunnels in Lausanne, her nervous, excited and scared laugh echoing in the six-foot tunnel; England, dressed in our school uniforms, trudging through the light British rain across a field at eleven years old, a shortcut to school, aping around to make her laugh, the cow pie crusty on top, mushy inside, my shoe filthy, her peal of laughter cutting through the misty cool morning air.

I wondered what she'd be like now, as an adult.

Her phone call had come while I was deep into writing code, wrestling with reducing a key script to a few critical bytes so I could hide it within a software program. It came at a very inopportune moment. I'd just had a brainwave. Instead of using the program, a small Trojan executable based on a zero exploit that, when scanned by anti-virus software, would insert a tiny script into the host computer, I'd hide the script in an image file. This was completely new; very intriguing. I'd just started contemplating how it might be achieved, what image file format would be most suited to it, and what trigger would be needed to activate the script, when my beloved old jet-black dial telephone, an anachronism, plugged into an actual land line, distracted me. The loud harsh ring almost made me forget my brainwave. That's probably why I was a bit curt.

I'd snapped "Hello" into the phone and been momentarily confused, not knowing who the hell was calling. It took Susan a couple of tries before I actually understood it was my sister calling. We hadn't talked in four or five years, drifting apart as a result of geographic isolation - Susan living in California - and different lives being led. But the one thing I'd immediately caught was the change in her voice; Susan sounded like a stranger to me.

Life was funny. Susan and I had been joined at the hip when growing up. Dad was an international business executive, which meant we moved frequently, lived in some very interesting countries and, with the difficulty of making new friends, especially when you didn't speak the local language most of the time, Susan and I were best friends. Then I went to university, Mom and Dad divorced, and Susan got married. The close family imploded and geographic distance became the new norm, birthdays slowly forgotten over time, contact becoming intermittent then almost non-existent.

Susan had, after taking a deep breath, asked in a hesitant voice if I thought I could handle a couple of guests for a while. I'd immediately asked her what was going on and, shocking me, Susan had made a sound like a sob or shaky inhalation; something I'd never heard from my feisty sister. She'd babbled about needing a break, that everything would be better if she could just have a break.

I had a disjointed conversation with her. It seemed her husband had left a year ago, the divorce still dragging on over custody disagreements and now turning acrimonious. Susan was drained, emotionally and physically. She was stressed, worried and close to losing it. "I feel like I'm on the ragged edge, Mark. I actually yelled at the girls the other day for no reason!" she'd explained.

The conversation had been long, two siblings slowly reacquainting themselves, testing hesitantly to see if familial bonds were still there. They were. I'd felt immediate concern; I was back in the tunnel in Switzerland reassuring six-year-old Susan it was safe, "Monsters don't live in the tunnel, Sis." I didn't hesitate in agreeing to have my nieces visit me for a while.

"Susan," I'd suggested, "A change of scenery would do you good, too. Come here; stay with me. It's miles away from San Diego and Burt, and his lawyers."

"Are you sure, Bro? You really wouldn't mind?"

"Of course not. Why would I mind? I have two unused bedrooms. The girls can sleep in one, you in the other."

Picking them up at Lester B. Pearson International airport, I'd been shocked and deeply concerned. Susan, normally a compact woman whom people usually assumed was a ballerina, was gaunt and far too skinny. She had dark shadows under her eyes, soft brown eyes that looked larger with her weight loss.

"Uncle Mark?"

Turning from the view of Toronto I looked at Zoë as she walked into the living room, giving her a smile. She was a little Susan, nine and all of three-foot ten, slender, thick black hair, darker than her mother's, trimmed to shoulder-length, a bright smile, excitement making her eyes glisten, her generous mouth curling.

"Hey. Find everything?" I asked. "By-the-by, you can call me Mark, okay?"

"Okay," she smiled, walking over to stand at the glass wall, peering out at the view. "How come you have such a big apartment?"

"I don't like mowing lawns," I answered with a grin.

Zoë turned and grinned back at me. Quite cute, I thought. "No. I mean how come you have such a big apartment, not why."

I smiled, impressed. She was sharp. "I work hard."

She opened her mouth to ask another question when Susan walked into the living room, pre-empting her. "Zoë, you can't just dump your clothes in a drawer. They'll get wrinkled. Go arrange them properly," she ordered in a stern voice, a slight frown on her face.

"Kay." Zoë gave me a chagrined smile as she left.

"Mark, you have a nice place," Susan said, sitting next to me on the brown leather couch. "What do you do that you can afford a penthouse?"

"Would you like a coffee? Or tea?" I asked, rising from the couch.

"Sure. Coffee would be nice. I'm tired from the trip."

"Come on." I took her hand and pulled her up, heading to the open-plan kitchen. Her hand was all bones, her slender wrist looking far too delicate. Susan was unhealthily waifish and it worried me.

"I'm a hacker," I explained while filling the Braun coffee maker with water.

Susan looked surprised. "You mean you steal credit cards and things?"

With a chuckle I clarified. "No. I'm a computer security consultant. I break into company's computer systems and then show them how to secure their systems properly."

"So it's legal?"

"Yeah. One hundred percent." Closing the coffee filter, I started the machine, turned and leaned back against the counter. "You're looking a bit ragged, Sue." In narrow-legged jeans, soft burgundy blouse, and Keds on her sockless feet, she looked frail. Susan had never been tall. Now, all five-foot four inches looked even smaller, her breasts noticeably small, hips too prominent and boney.

"I haven't had much of an appetite these days."

"Well then, I'll fatten you up. That'll be my job," I told her with a grin. "It'll be fun to see you fat."

She chuckled without amusement.

We chatted while the coffee-maker gurgled behind me, reintroducing ourselves now we were adults. Susan was thirty-three, three years younger than me, dark brown hair styled in a rough layered cut, short with fringes and feathers that accentuated her delicate face. If she hadn't been gaunt, she'd still be quite pretty I decided, sort of pixyish; just like when she was young.

I wondered what had happened to her, asked, and wished that I hadn't been curious. My blood stirred when I heard about the verbal abuse and, without ever seeing Burt, I knew I'd kill him if I ever set eyes on him. He'd changed my firebrand sister into a shadow of herself. I saw only fragments of her strong will, eyes glistening from tears held back as she calmly talked about the abuse, her arms hugging her slender body which seemed to take on a defensive posture. I hated seeing what Burt had wrought. He was a verbal bully and, to make matters worse, was starving her of money in order to get custody of Olivia and Zoë.

Thank goodness we were interrupted just as coffee was poured, Olivia strolling into the room, eyes taking everything in, the huge living room, the open plan arrangement with a dining area and the large open kitchen. She grinned at her mother sitting at the counter separating the kitchen from the living room. "I like it!" she exclaimed with a big smile.

Susan spoke before I could say anything. "Did you unpack properly?" she asked firmly, so much the mother.

"Of course I did, Mom. It's pretty, Uncle Mark," she added looking out at the view. "I thought Canada was all snow."

Olivia was, at twelve years old, willowy with a dancer's grace in her movements just like her mother, mature restraint in her carriage, and a personality that was softer than Zoë. She was a preteen on the cusp of teen-hood trying to portray sophistication and worldliness. She had her mother's dark brown hair, long and pulled up in a ponytail, and dark gray eyes that, I assumed, came from her father, since Susan's were chocolate brown. Olivia stood about five feet tall, and was inquisitive. No. More like nosy based on how she was casually opening cupboards and looking inside drawers. Her eyes seemed older than twelve, though, observant, knowing and assessing.

I'd never met either niece before, but liked them both. "Olivia, call me Mark," I suggested.

Susan interjected, "Or Uncle, I think."

"No. Call me Mark. I insist," I said with a defiant smile, Olivia looking alternately at me then her mother.

Susan smiled back at me sweetly. "Or Uncle," she disagreed.

"My house, my rules," I told Susan. "Let's compromise." I turned to Olivia. "Call me Sir," I suggested with a grin. Susan snorted laughter behind me. Olivia let her youth out with a giggle and a remarkably pretty smile.

"Sir," she asked coyly, "Can we have dinner soon? I'm hungry."

We ate at il Fornello at the harbour front. It was a bit cheesy for me; too touristy. They enjoyed it, though. As they ate wood-fire gourmet pizzas we chatted getting to know each other, building familiarity and ease. Susan perked up slightly as she told Zoë and Olivia embarrassing stories about their uncle, all of which I denounced as complete fabrications; unsuccessfully it seemed.

As we got to know each other I studied the differences; Olivia, slightly more restrained, was trying to be an adult, yet her youthfulness would break through with an occasional attractive giggle; Zoë, an uninhibited spirit that reminded me of her mother when she was that young, was fearless, charging forward even when cheeks flushed red from embarrassment. She was full of spit and vinegar.

But Susan was different. I didn't know if it was being an adult, being a mother, or being verbally abused by a good-for-nothing, bully-of-a-husband. She was not the person I grew up with. It preyed on my mind even when I went to bed later that night.

That night in bed, Olivia turned on her side towards Zoë. "Uncle Mark's cute," she said. "I like him."

"Yeah. Doesn't look like Mom's brother, though," Zoë said.

"Yes he does. You've got to look at his eyes. They both have the same eyes."

Zoë giggled. "I didn't pay attention. Too busy looking at his butt. Jeez it's like, compact. I wouldn't mind grabbing . . ."

"Zoë!" Olivia chastised, "He's our Uncle!" After a moment of thought, she giggled. "You're right. He's got a sexy ass."

Over the next several days a routine developed. They let me work undisturbed in my home office till noon; I was an early riser, up at four in the morning, at my desk by four-thirty with java at my side, dual screen monitors providing the only light in the early darkness. Mornings and late nights were my most productive times. At noon it was off to a restaurant, afternoon sightseeing, or strolling along the noisy, eclectic Queens Street West, and evening dinner at home, me cooking. I was an accomplished chef and the kitchen reflected it with modern appliances, high-end cooking utensils and a vast array of interesting spices.

I was pleased to see Susan slowly begin to eat, not just pick at her food. And it was a Friday night when we actually talked, opened up a bit to each other, and rediscovered the closeness we'd lost over the years. Olivia and Zoë had gone to bed, tired from a visit to the Toronto zoo, a vast open-air zoo that made us walk to exhaustion. Susan and I sat on the couch, slightly turned towards each other, glass of white wine in our hands, music playing softly, and the occasional distant blare of a car horn making it up from the street below. The CN Tower was putting on another colourful LED light show, patterns of pink celebrating the fight against breast cancer. We were reminiscing about our time in England and how our lives had evolved. It was very relaxing. I liked the animation returning to my sister's face.

Susan studied her brother as they chatted. He'd changed in the fourteen years since she'd last seen him, yet was still the same. At five-foot ten or eleven, he appeared taller from the way he carried his body, upright with a confident angle to his head. He had a way of looking directly at her that gave her the impression she was the only thing he was seeing, his intense dark brown eyes penetrating, as though he was seeing inside her. She knew it wasn't true. You could be in a complicated debate with him and he'd suddenly refer to something someone across the room had said, or comment on something that he'd just seen on TV. She'd swear he was completely focused on her, yet he wasn't. His mind seemed to be running on full throttle all the time, never a down moment.

She saw his youth appear in how he'd grin, his mouth widening, lips curling, white teeth appearing, a boyish glint making his dark brown eyes sparkle. In those moments he looked so much younger than his thirty-six years, more like early twenties, or younger. He had an impish grin, the type that let you know he was thinking of something out of character for the situation; something shocking designed to embarrass just for the hell of it. His dark brown, almost black hair was in desperate need of a trim, a thick mop falling to the base of his collar at the back and almost into his eyes at the front. Now, at ten-thirty at night, he had a day-old shadow darkening his chin. He looked good with it, she decided. Her brother was handsome.

As they talked, she noticed how he observed her, his eyes studying her even when he was laughing or telling her some made up story of his technical prowess, his mind operating on two levels. She felt the old comfort with her brother return, an easy familiarity. The wine, a nice Canadian Zinfandel, helped her relax, too.

". . . and, when the Pentagon found out how far I'd penetrated their purchasing system, General McKinsey just about shit his pants," he was saying with laughter. She'd temporarily lost track of his story.

She interrupted him, overcome with a flush of sisterly love. "Thanks, Mark," she blurted.

"For what?"

"For caring," she answered. "And for letting us stay here with you." She truly felt away from the trouble Burt had caused, the stress, anger, and yes, fear. She couldn't imagine losing custody of her girls.

"Sis, you've always been welcome here. You know that."

She watched him tilt his head just so and smile with warmth. It brought with it a strong memory. She blushed, then chuckled. "You were my first, you know," she said with a soft smile, memories now streaming back with familiarity.

"First what?"

"My first lover," she said with a light embarrassed laugh.

"I was your . . ." I didn't finish the sentence, a bit surprised by Susan's casual comment, puzzled, too.

She laughed. "Yeah, I was fantasizing about you when I experienced my first orgasm."

"You were?" I liked hearing her laugh.

She looked at me, soft eyes bright. "I think I had a crush on you. No. I definitely had a crush on you. You took me to the movies and then held my hand all the way home. Remember? The Addams Family?"

"Sorry." I couldn't remember that specific event. I probably held her hand to stop her running into the road.

Susan laughed and gave me a big smile. "I was nine. You were a pretty good lover, too, as I remember it," she said. "Look, my brother's blushing!" She laughed again and reached across the couch and took my hand. "Cute."

I grinned. "Well, since we're playing truth, you were my first, too," I said.

Her brown eyes regarded me carefully. "I was?" she asked, her voice contemplative.

"The first naked female I ever saw," I said.

The memory flashed back. I got the same reaction I'd had twenty-one years ago, a physical reaction that made me fidget on the couch and cross my legs casually. It was a deeply profound accident. It had formed my sexual perspectives and defined what I found attractive in females. Susan had been in the tub, headphones on listening to music on her Sony Walkman, her eyes closed. She was twelve.

It was perhaps five seconds, a long, long five seconds, before I backtracked and closed the bathroom door, a full erection straining my jeans even though it was my sister. Nothing had prepared me for how much better a naked female was in real life. Pictures couldn't hold a candle to the sight of real female flesh.

I didn't even try to feel guilty about it when I beat off in my room. Susan's body had just started developing. Her breasts were small mounds almost conical under the water. She had dark pink areolae that seemed large on her small breasts, and little nipples, two soft peas. Her body was slender, a precursor to what she'd grow up to be. Yet, with her sides flared out around her hips and her bottom pressed to the bathtub, she had incredibly sexy curves.

But the sight that, to this day, I could still picture vividly was her pussy. It wasn't bare, nor did she have a pubic bush. It was somewhere in between, newly sprouted individual pubic hairs. I could see every detail of her pussy, the prominent sensual mound of her pubis tapering so sexily to a gap at her crotch, two thick lips forming a deep sexy slit and, nestled into that seductive cleft, a small clit peeking out about half way down. Susan had dark little pubic hairs sort of sprinkled on her pussy and labia. It was an intensely sexy and incredibly arousing sight for a fifteen year old.

Susan's thumb, rubbing the back of my hand softly, brought my attention back from cherished memories.

"So tell me. When did you see me naked?" Susan asked.

"I don't think so," I said, embarrassment warming my body.

With a smile, Susan suggested we watch a movie and have coffee, adding, "Do you have any cognac?"

As Roman Holiday started on TV, Audrey Hepburn appearing, so delicate and slender, I took a sip of coffee. Susan slipped to my side, drew my arm up and over her shoulder.

"So tell me, Bro, when did you see me naked?" she asked again in a soft voice.

"Thought so," she said when I told her. "I saw you leaving."

Silence filled the room, comfortable, Susan sipping her cognac, Audrey Hepburn looking spectacular as she dismissed Gregory Peck's attention with an attractive coy smile.

Susan took my hand, her thumb rubbing gently, almost absentmindedly. "Did you picture me when you, you know, masturbated?" she asked softly.

I smiled and felt warm embarrassment again. "Well, given you were the only real naked female I'd ever seen, what do you think?" I said.

"It didn't bother you that I was your sister?"

"Hey, boy? Fifteen? Of course not."

Susan's face turned up, eyes soft, smile gentle and open. "Did you ever imagine having sex with me?"

"I was fifteen, horny all the time and a virgin. Of course I did," I told her, "Quite frequently, as a matter of fact," adding with an embarrassed smile, "You were quite adventurous."

She whispered, "I dreamed of you, too. I'd be in bed wishing you'd come to my room. I was pretty naive. But, you paid more attention to me than anyone. Sometimes, I . . ."

She paused, our eyes looking at each other, my sister now an adult and a mother, still somewhat gaunt, and I saw Susan at twelve, her face shining with life, personality that took control of the room. I saw Susan in the bathtub in all her pubescent glory and felt my penis stir.

She reached up, her hand caressing my cheek. I didn't resist in the slightest. I kissed my sister gently, closed mouth. It was thrilling.

Something happened. An unspoken barrier had been breached. Susan smiled, eyes glistening with pleasure, and rested her head into the crook of my shoulder. "I always wanted to do that," she said softly. Without another word, we watched the movie, the air now full of sexual tension.

Susan sighed to herself quietly. Sitting with Mark was such a different experience. She couldn't remember when she'd last been relaxed with a man, any man. For that matter, she couldn't remember a man talking to her gently, without an undertone of sarcasm, or the biting tone of disapproval. How could she have been so fooled by Burt? Feeling her brother's arm around her was calming and exciting in an illicit sort of way. She remembered imagining her and Mark together when she was young. She smiled as she wondered what it might have been like if . . . Hold on! He was here now. Maybe. She shivered lightly, tensed, apprehensive, inhaled deeply and drew his hand close.

At the point when Audrey Hepburn was at the Trevi fountain, Susan pulled my arm across her, gently guiding my hand to her small breast. I developed an immediate erection, memories of how I'd lusted after her small breasts when I was fifteen storming back. My erection strengthened when I gently cupped my sister's breast, felt her bra underneath her blouse, and rubbed her nipple slowly with my thumb. Susan's breast was still small, just under a handful, really quite perfect. For the rest of the movie with a hard erection straining in my jeans, I gently fondled my sister, teased her nipple into hardness, sipped cognac, and thrilled at the situation; so illicit yet so exciting. I was living an old, never-forgotten dream; touching my sister's breast.

When the movie ended, Susan took my hand off her breast, "Come," she said, smiling gently as she stood, pulling me up.

It just felt natural, as if it was destined to happen ever since our youth. It didn't even cross my mind that perhaps I shouldn't let this develop. Looking at Susan, I saw my little sister, that twelve-year-old that had fired my sexual dreams. She had formed what I found attractive in women. Every girlfriend I'd ever been with was of a type; petite, slender, dark haired with small breasts.

I followed her as she led me to my room, incapable of resisting, unwilling to resist, turning lights off as we passed, watching the sexy swish of her compact rear end under a pleated blue skirt, and appreciating her slender calves, narrow ankles, and dainty dancers' feet.

She turned when I closed the bedroom door behind me, moved close and pressed herself to me, her face turned up. Two slender arms slipped around my waist pulling me closer; I felt her press her slender body against my erection, saw her awareness of my aroused state in a soft, sexy smile curling sweet lips and a glint of excitement in her eyes.

"Feels good, Mark," she said, her eyes watching me. "You can hold me," she added when my arms hung at my sides. She rubbed against me. "It feels big. Is it?"

"Sue, I don't want you to regret . . ."

Susan's finger touched my lips, stopping me. "Never regrets, Bro." Her gaze became inquisitive, contemplative. "I used to wonder what your erection looked like. Now I want to find out."

I didn't need much encouragement. I saw Susan back then in my mind, and saw her now, a mature version of then, still attractive, still my type. A small tremor passed as I contemplated kissing those red lips, that sexy mouth, suddenly incest adding a delicious layer to my arousal.

Susan felt slender and petite when I wrapped my arms around her. Her lips were soft and yielding, moving seductively against mine. Her eyes closed as if concentrating on my kiss. She emitted a sexy purr and melted against me, pressing her small breasts to my chest. My erection strained in my jeans as I tasted cognac on her lips. My hands held two sensual firm buttocks.

Twin monitors cast a glow on the desk, lines of code scrolling down the DOS box. I leaned back and sipped a morning coffee, keeping one eye on the progress being made. Bank of America, Burt's bank, was about to open to me like a cheap whore spreading her legs after being flashed a c-note. A financial misfortune was step one in Burt's involuntary redemption. I'd decided a little blackmail might be in order.

I let my mind drift back to last night as the program did its magic.

Susan had felt good in my arms. There was a special excitement feeling her bra strap on her slender back, such an intimate piece of clothing. It was so sexy the way she opened her mouth and let my tongue in, let passion storm in. Kissing my sister was incredibly arousing. Her hands started wrestling with the button of my jeans. And suddenly, there was frenzied desire as if everything that had been pent up for years was now bursting forth, fuelling our need.

Suddenly we were tugging at clothes, Susan emitting heated murmurs as she pulled my shirt over my head, pausing to let me strip her blouse from her, her fingers immediately unzipping my jeans and tugging them down. I found the clasp on her skirt, opened it and, as my jeans fell, her skirt dropped to her feet. It was as if it was a sign. We both paused in our frenzied undressing of each other and stared, eyes absorbing the intimate view.

In her unassuming lingerie, little cotton bikini-style panties and a small half-cup bra, white with sky blue patterns, Susan looked almost child-like. I could see her ribs, her body still slender, breasts petite, yet the sexy curve of her hips, the swell of her rear, and slight gap between thin thighs was very attractive. I liked how she casually studied me, her eyes moving up from my feet to my face, pausing at my groin, erection straining as it tented my boxers.

So close to being naked in front of her, I paused, a bit embarrassed. She smiled at me, her eyes bright and shining.

"So, let me see," she said softly, reaching for my boxers. Her fingers were cool against my stomach when she slipped them into the waistband. Pulling it out from my waist, she lowered the boxers over my straining cock. I was very excited, my penis standing slightly north of horizontal, feeling tight; a strong erection.

"Very nice," she said staring. Then, she looked up at me and smiled, "It's bigger than I imagined." Her soft hand curled around my shaft, holding me gently and sending a strong pulse of pleasure though me.

"My turn," I replied, reluctantly removing her hand.

Both of my hands trembled while I fiddled with the bra clasp between her breasts, nervousness and excitement making me unusually inept. Susan's hands came up and steadied mine, her cool slender fingers guiding me. A snick sounded loud. I stared. When she shrugged off the bra, letting it drop to the floor, I stared rather rudely, struck by the beauty of her. Still petite, her breasts had changed from what I remembered. Now they were rounded and fuller, a seductive gentle slope above, sexy rounded fullness below. Despite two children they sat firm and proud on her. Her areolae had darkened, now a dusky pink, almost brown, her soft nipples larger than I remembered.

They were perfect, exactly as I liked, petite, not quite a handful and as sexy as hell.

I bent, trembling as I reached for her cotton panties, loving how they formed to her pubis, how they emphasized her seductive mound and the deep creases that formed an arousing v-shape. My erection pulsed when I saw a couple of dark pubic hairs escaping from the waistband. Knowing it was my sister's pussy I was about to see, my sister's panties I was about to remove, made it so much more exciting. And it was. Susan had a beautiful bush, full yet trimmed neatly, dark brown curly pubic hair. Her pussy, on her slender body, seemed large, filling her loins, seductively plump, intensely attractive.

Tearing my eyes from her pussy I looked at her, saw an almost shy expectancy in her face. "Sexy," I said, "Very sexy."

She smiled at me, moved close and pressed her naked body against mine, my erection poking her in her stomach, sliding up and leaving a slippery trail of precum. Her kiss was passionate, her tongue animated and forceful as if she was starved for sex. Our kiss became frantic, moans of desire in the air, her hands caressing my naked back as I groped her sexy ass. Before I knew it we were in bed, side by side facing each other, Susan moving her body against my erection as she kissed me with urgency, murmuring into my mouth. I had a seductive buttock in my hand, my fingertips probing deep. I touched her pussy, shuddering at the warm silky moisture that welcomed me.

Passion stormed in, assaulting me, a driving need emerging. I was feeling up my little sister, my sexy little sister; something dreamed about so many years ago. God, I was touching my sister's pussy, her aroused pussy. When Susan's hand took hold of my aching cock, I traced her cleft, letting the tip of my fingers slip between warm moist labia and slide through her silky cleft. Her kiss intensified when I felt her clitoral hood, and became more passionate when I rubbed her clit, her leg rising to hook over my thigh. She moaned and, gripping my erection, started stroking it, milking precum from me, her thumb rubbing it around my crown.

The heat of passion descended, the excitement of fondling my sister after so long just too stimulating. Moaning myself, I probed the opening to her vagina, letting the tip of my finger slip into her tight, velvety warmth. It held my fingertip snugly and I wondered how it would feel to slip my cock into her, what it would be like to fuck my sister, my arousal spiking, erection throbbing.

Breaking the kiss, I bent to kiss her petite breast. Susan rolled onto her back, opening herself, her fingers combing through my hair, guiding my head, moving my mouth from one breast to the other as I gently sucked her nipples, feeling them stiffen and grow with excitement. Her musky scent mixed with her perfume, an aroma that seemed to pierce my brain.

"I need you now, Bro," she panted, tugging my head up, her knee worming under me. She pulled at me desperately, pulling me on top, her knees rising to cradle my hips, her feet sliding up my calves. Susan reached down between us and, when I lifted my body slightly, she took hold of my erection. She moaned and rubbed the tip through her cleft, silky and slippery. "You're so big," she whispered, her hips beginning the motion of love.

Suddenly I was at her entrance, lodged between sexy labia, warm slippery moisture against my erection. Susan grasped my buttocks, "Fuck me, Mark," she urged, curling her hips and tugging, "Please fuck me."

I felt that exquisite sensation of penetration, that unbelievably good feeling of a vagina, warm and moist, dilating and squeezing over my straining crown, the seductive warmth of my sister's pussy gradually surrounding me. I was shaking as I slowly penetrated her, my erection slipping into a velvet sheath, hugged tightly, my sister's pussy, my sister's pussy! I slipped into heaven, slid deep, her velvet vagina surrounding my shaft in erotic heat. Her pubic hair tickled my groin. I was in, completely buried in my sister's vagina. Jesus, I was fucking my sister!

She clutched at me, whispering in my ear, "So good, Mark, you feel so good," her body trembling underneath me. My erection swelled, buried in seductive warmth, each pulse making her feel even tighter, the crown expanding.

"God, Susan," I gasped, "I can't believe we're doing this." Need for release was pounding me. It was like I was on a short fuse, the excitement of fucking my sister just too much.

"Please," she moaned with a clench of her pussy, her hands pulling at my ass.

We started fucking each other, long strokes, delicious arousing strokes, slippery, silky, out, in, God, fucking my sister. Moans filled the air as we fucked each other faster, more urgent, Susan clutching my butt, tugging hard, her pelvis curling up to drive my aching cock deep, so deep. We fucked harder, wet slapping sounds, thumping against each other, so illicit, so erotic, so damned exciting.

"Mark! Oh God, Mark! I'm . . ."

Susan's orgasm started. She inhaled sharply, her body surging up off the bed to bury me deep. Her vagina clenched, her arched body froze for a second and then, with a whoosh of breath, she hugged me tight and went wild, her body writhing under me as I held two sexy buttocks and fucked her hard.

"Oh God, oh God," she gasped.

She writhed and humped under me, clutching, pussy clenching. "Cumming!" she cried out as I ploughed into her with hard thrusts, her body losing rhythm, jerking from her climax, Jesus, my sister cumming! I fucked her harder, desperation beginning.

When her climax peaked, she relaxed slightly, her muscles loosened, her vagina not gripping me so hard as I fucked her with long, deeply satisfying strokes, my own climax hovering near, my own need for release driving me on harder, the sweet fog of intense arousal descending.

"Don't stop," she gasped when I suddenly pulled out of her sexy pussy.

Rising to my knees, I flipped her over onto her front, straddled her thighs, caressing her sexy pear-shaped ass and rubbing her sexy firm buttocks. Holding my slippery shaft, I nestled the tip into her crotch. Susan moaned and curled her ass up, the tip of my erection slipping down across her rosebud and over her perineum to nestle at her very moist vagina. I throbbed and pushed, stretching her entrance, the sight of my crown squeezing into her pussy so incredibly sexy. In one stroke I buried myself in her and collapsed onto her back. With one hand I reached under her to fondle her small breast, my other hand burrowing underneath her to cup her sexy pussy and rub her clit, her slit wet with our secretions.

With her sexy buttocks in my groin, I fucked her, thrusting in and out of her velvety pussy, fucking hard, almost desperately, sweat forming. I fucked my sister, my climax approaching, erection swelling, chasing nirvana, painful, gotta cum, gotta cum.

"God, I love being fucked from behind," Susan groaned, clenching her buttocks tight.

"Almost there," I gasped, fucking her hard, my erection straining painfully, thick, hard.

"Cum. Cum in me, Mark," she urged in a quiet, intense whisper, her ass undulating against me.

Her urging me to cum in her was the final straw, my climax rushing in and hitting me like a strong wave. It crashed over me, erection swelling painfully. I moaned loudly as pressure released, semen burning up to spurt into her. Pulling out, I thrust my erection deep, bouncing against her buttocks, lodged my erection as deep as I could, pulling her pussy to me. A huge wave hit me, hot semen exploding into her velvet pussy. Oh, God. "Cumming," I gasped.

I humped again, cum blasting out almost painfully. The rage of my orgasm took over. With desperate short strokes and Susan clenching her sexy buttocks, I came hard, spurting deep, "Jesus, cumming Susan," I gasped, fucking her hard, her pussy slippery, hot, tight, glorious pleasure flooding me with each intense spurt. I came, I came, God I came.

"Incredible," I sighed when I finally slowed, satiated, heart pounding, erection pulsing gently with the last traces of cum, Susan's petite body feeling so good under me, an age-old fantasy realized.

Sitting in front of the computer and watching the code scroll down, sipping coffee, another erection formed at the memory of last night. I'd fucked my sister and fucked her with a desperation I'd never felt before. And the crazy thing was, I wanted to do it again and again. It was great sex, exciting and illicit.

A beep drew my attention. The DOS box changed, Burt's accounts rolling onto the screen. Taking another sip of coffee, I bent forward, flexed my fingers. So, Burt, time to pay up.

Susan woke slowly. She smelled Mark on the pillow. As she rolled to her side, she smelled sex wafting out from under the sheet. She ached between her legs, a sensual ache, a welcome ache. It made her smile. It was the ache of great sex.

Pulling the pillow to her face, she inhaled deeply. Last night had been so intense. She felt a tickle of arousal just remembering. With a grin she remembered how thick Mark's erection was, so much thicker than Burt's. Not having had sex for over two years, it had felt like she was a virgin again. She'd stretched so much, almost to the point of pain. But, God, it was incredible. Mark's erection was so filling. It had touched parts inside her Burt had never reached.

Lazy in bed, she thought back to the climax she'd had as Mark fucked her. It had been like a gun going off. She'd felt her body go rigid, her climax exploding, pure bliss storming into her from her pussy to her breasts to her brain, pleasure blossoming in an intense orgasm, Mark's large erection caressing her deep, so deep.

Susan cupped her sore pussy, smiling at the mess, Mark's semen still leaking out. Last night she'd felt her vagina clench around his wonderfully big cock, pleasure storming into her, so good, so much better than she was used to. And, when he'd turned her over and thrust into her from behind, she'd loved it; her brother fucking her. With a sigh, Susan remembered Mark cumming in her. She'd actually felt his erection grow, get thicker and pulse as he climaxed. His gasps were beautiful. He was better than any other lover she'd had; all three of them.

Rolling out of his bed, she gathered her clothes and headed for the shower in her room, her mind preoccupied, wondering if Mark might like to do it again, hoping he would. She felt wonderful. Did he have regrets now in the harsh light of day? She didn't.

Zoë elbowed Olivia as they sat at the counter separating the living room from the kitchen. "Look," she whispered to her sister with a grin, "Mom's humming. I wonder what's changed?"

Olivia looked and smiled. Mom hadn't hummed in eons. She used to hum to herself all the time when she was happy. But for the last several years Mom hadn't been happy at all. Yet there she was, cooking breakfast, a wistful smile on her face and humming. It was really nice to see.

"So, Mom," Olivia asked, "How come you're so happy this morning?"

Both girls were amazed to see a bright red blush flower on her face.

"I . . . It's just good to be here," she mumbled, embarrassed at having been caught dreaming of sex with her brother.

The girls dismissed it from their mind, just glad to see Mom happy. But, when Uncle Mark appeared just before noon and they both saw him hug and kiss Mom on her cheek, they'd have accepted it as the affection of a brother if Mom hadn't blushed bright red again.

That night in bed, Olivia whispered to Zoë, "There's something going on, Zoë."

"With what?" Zoë asked, flipping the channel on the TV searching for a good movie.

"With Mom and Uncle Mark. Didn't you see Mom blush?"

"Yeah. So what?"

"Think, Zoë. When he kissed you on the cheek, did you blush?"

"No."

"So what would make you blush?"

Zoë paused from channel surfing, thinking. "Oh m'God! You mean . . .?"

"Yeah. See?"

"You think they're . . .?" Zoë asked, awe in her voice.

"I dunno, Zoë. But what else could it be?"

"Jeez, Olivia. We've gotta find out. How can we find out?"

The two started whispering furiously, both fascinated by the possibility Mom might be getting it on with Uncle Mark, finding it difficult to picture. Olivia found it vaguely disturbing, a brother and sister? Incest? Zoë was surprised, yet excited, too. Mom and Uncle Mark? Wow. They talked excitedly, Zoë pointing out how happy Mom was, so how could a roll in the hay with Uncle Mark be bad? Reluctantly Olivia agreed, and then wondered what they were doing, her mind conjuring up all sorts of sexy images that made her feel warm.

"What was that? Did you hear it?" Olivia asked, her ears straining to see if it came again.

Down the hall, Susan cried out, her body straining, almost cramping from the orgasm battering her body. She'd been able to keep the first climax quiet as Mark caressed her pussy, but the second had stormed her suddenly when Mark started sucking her clitoris, his fingertip slipping into her ass and another teasing her g-spot. It had crashed over her, overwhelmed her, Mark's face buried in her crotch, her knees clamping together as she squeezed her breasts painfully hard, her hips surging up. She came hard, tears forming, lights flashing like fireworks in her head, body heaving, pleasure flooding her, pleasure, bliss, bliss.

"Stop, stop," she gasped, shoving his head away from her crotch, her body jerking and twitching uncontrollably. It was too much, way too intense. Susan rolled on her side cupping her pussy, trembling, hips spasmodically jerking as her orgasm faded. She felt Mark cuddle up behind her, felt this arms wrap around her to hug her gently, felt him kiss her hair softly, and she burst into tears. Burt had never given her oral sex like that, hadn't ever given her such an intense orgasm, nor had he ever shown as much affection by cuddling her after sex.

"Hey. Are you okay?" I asked quietly. I'd never had a girl cry after an orgasm.

"Wait," she whispered.

I held Susan's slender body, feeling her calm down. Eventually she turned in my arms, soft sexy brown eyes only slightly red, a glorious smile emerging.

"Jesus, Bro. I've never cum so hard." Then she grinned, "You're MUCH better than I dreamed of back then."

Smiling myself and feeling quite the Romeo, I asked, "So why the tears?"

For just a moment, Susan's face grew serious. "Burt never did that to me. I never knew."

"Did what? Never knew what?" I asked.

She smiled, a sparkle returning to her eyes. "That asshole never gave me proper oral sex. I never knew oral sex could make me cum so hard. Jeez, for a moment there, I felt like I was going to pee. I had no control over my body."

I grinned. "Guess what? You did."

"I peed?"

"You squirted."

"Oh God!" she gasped. "I'm so sorry!"

I watched her face turn bright red, shock and embarrassment blossoming. "Hey, relax. It's normal. Actually," I added with a grin, "you tasted delicious."

Susan smiled shyly, her blush intensifying. Her hand slipped between us and held my erection. "My turn," she said with a mischievous grin, nudging me onto my back. When she tested my erection by squeezing slightly, she asked, "Did you ever dream of me giving you a blow job? Like when I was twelve? . . . Oh, you did," she exclaimed as my penis swelled in her hand.

She looked at me with love in her sexy eyes, bent, kissed my lips gently, mouth closed, moved her lips to my ear, "I would have, if you'd asked," she whispered.

I groaned at the image it conjured in my mind; Susan, twelve, petite, slender, perky little breasts, pretty, pretty face lowering to my erection. "Now I wish I had," I said heatedly.

Down the hall, Olivia slipped back into their bedroom. "She's not in her room! Come on!"

Two girls slipped out of their room and tiptoed down the hall, ears pressed to an Uncle's closed bedroom door, both grinning at what they heard faintly, ". . . a blow job? Like when I was twelve? . . . Oh, you did."

Back in bed, Zoë couldn't hold back. "Can you believe it? Mom? Giving Uncle Mark a blow job when she was twelve?" she exclaimed. When Olivia didn't answer right away, she added, "You're twelve. Would you give Uncle Mark a blow job?"

Olivia blushed as she imagined what it would be like to give a guy a blow job.

Twin monitors cast a glow on the desk, lines of code scrolling down the DOS box. I leaned back and sipped coffee, one eye on the progress being made. Today, Burt's investment accounts with Morgan Stanley were in the cross hairs. I was impressed with Morgan Stanley's security. After almost two hours I was still knocking at the door. But as code scrolled down I saw a pattern emerge. It wouldn't be long before both Morgan and Stanley welcomed me with open arms. An investment misfortune was step two in Burt's involuntary redemption.

I let my mind drift to last night.

Sex with Susan was incredibly exciting. She had climaxed twice, the second time spurting into my mouth, something I'd only heard about and never experienced. But the way she smiled at me when she held my erection, so sexy, her eyes shining, had made my heart thump. She didn't stroke my cock so much as caress it and it felt so loving for some reason. Small tremors of excitement had shaken me when her thumb caressed the tip, spreading slippery precum.

"You've got a beautiful erection," she whispered before bending to kiss the tip. "Mmmm, tastes good, too."

Kneeling at my side, I noticed how shapely her breasts were and reached out to gently stroke the nearest one, full with heft, yet wonderfully petite. Susan had moaned and pulled my hand away. "Don't. You're distracting me," she said.

"But they're so sexy," I complained.

"Don't. I want to try something I never tried with Burt."

Susan let my erection rest flat in her palm, her other hand gently caressing my balls. My erection twitched up off her palm when she softly kissed my testes. Then she kissed the base of my erection and started kissing her way higher and higher, agonizingly slowly, a kiss then a teasing lick, a kiss, a teasing lick. Before she reached the crown, she gently gripped the shaft pointing it straight up, her soft lips descending, my heart pounding, and slowly, oh so slowly, Susan slipped her warm mouth over my erection. I was shuddering by the time her lips popped over the flared ridge, shaking when her tongue started caressing and probing the pee hole. My vision narrowed when she sucked, erection swelled, her cheeks indenting, then groaned as her lips slipped down, watching in amazement as Susan took two, then three, then four inches of my shaft into her, her lips stretched so sexily, the crown pressing into her throat.

She pulled back and kissed the tip, lovingly caressing the shaft with her thumb. "Nice, Bro," she whispered, "You taste good. Do you like it?"

"Fuck, Susan," I managed to gasp before she descended again, lips slipping over me, warm mouth encompassing my crown again, slipping me deeper. I shuddered again when her throat squeezed, my erection swelling. She pulled back.

Two dark brown eyes looked at me. "Ready?" she asked softly with a smile. I could only nod. "I want you to cum in my mouth. I want to taste you," she said softly and bent again.

Susan started stroking my shaft, her sexy mouth descending, taking me in, slipping me deep, her throat touching the tip. She pressed down, throat pressing to my crown, pulled up slightly, sucked, her tongue caressing then down again. She started moving rhythmically, up, down, one hand holding my balls, the other stroking my shaft as she fucked me with her mouth. I reached for her head, held it gently to feel her bobbing on my penis, my sight alternating from watching her petite breasts moving seductively and her sexy mouth fucking me. My orgasm stirred at the sight, pressure building, sensations bombarding me. Jesus, my sister was sucking me off!

When she pushed her mouth down, opening it wider and swallowed, slipping my cock slightly deeper into her throat, it was too much, far too arousing. I felt the sudden release of pressure. "Cumming," I managed with a gasp, my erection swelling painfully as my hips jerked up. Semen burned up my shaft, crown expanded and cum exploded into her throat. She swallowed, squeezing my crown painfully tight and moaned. Another hard pulse shook me, cum exploding, a huge pulse, my climax erupting, pleasure crashing through me. Susan gagged and pulled up slightly. In the sway of an intense orgasm, Susan sucked my crown. I swelled and spurted hard, grunting out my intense pleasure, swelled and spurted, cumming into my sister's mouth, pleasure flooding my senses, hips jerking. I came, cum jetting out, jetting out again, cumming, pleasure crashing into me. I came hard, straining to ejaculate, pulsing, so beautiful, ecstasy flooding me.

The computer beeped. Taking a sip of coffee I leaned forward and studied the security protocol at Morgan Stanley. Typing quickly, I penetrated their firewall. A few more keystrokes and the program started hunting for Mr. Burt Harper's investment account.

In the kitchen, Susan smiled to herself as she prepared breakfast for the girls, cereal and fruit, simple and healthy. She felt a tickle of arousal in her pussy when she replayed Mark cumming, his thick semen jetting into her mouth so strongly. He had so much more cum than Burt ever had. In fact, it had almost choked her. She grinned. Imagine! She'd given her brother a blow job! Her pussy tingled. Damn, sex with Mark was so illicit and exciting.

"Morning, Mom," Zoë said.

Susan turned. Zoë climbed onto the stool at the counter, hair messy, and a grin on her face.

"Where's your sister?" she asked.

Zoë made a face. "Still pampering herself. Jeez, Mom. You'd think jeans are jeans. But not for Olivia. She must have tried on three pairs before I left and still hadn't decided."

Susan was about to respond when Olivia appeared, hair brushed, her skin glowing from a recent scrubbing.

"Hey, Mom. Sleep well?" Olivia asked with a sly smile.

Susan blushed, heat growing from her chest to her face. "Yes. Very well. You?"

Zoë and Olivia looked at each other. "Well, go on," Zoë said, elbowing Olivia.

"Mom," Olivia started. "Are you, like, sleeping with Uncle Mark?"

Susan's heart stopped; panic rushed in. "Why would you think that, Olivia?" she asked, her pulse suddenly returning, heart thumping in her chest.

"Cuz. We went to talk to you last night and you weren't in your bed. Then we heard these noises from Uncle Mark's room," Olivia stated matter-of-factly. "It sounded like you two were having sex."

Zoë interjected, "And yesterday you were humming and smiling all day and you haven't done that in, like, eons, Mom. You were happy! So, if you and Uncle Mark are, like, wow. It's nice, sorta exciting. Are you?"

Susan's face burned, heart palpitating. God, they knew! Oh God, what if Burt found out? She'd lose custody! "Listen . . ." she started saying, suddenly panicking.

Susan's conversation with her girls took a surprising turn.

"We've got to talk."

I looked over my shoulder at Susan. She'd quietly opened the study door, or I was deeply concentrating, because I didn't hear her. Poor Burt had just suffered a setback with his investments and I had carefully worked my way out of Morgan Stanley's system so no trace remained of my little visit. Step two in Burt's involuntary redemption was complete. Step three next - credit cards.

"Talk about what?" I asked.

"We have a problem. The girls know about us," she said.

I felt my chest constrict. But, instead of fear, Susan grinned at me! That seemed odd.

She came over to me, swung my seat around and settled into my lap. Nice. Her weight reminded me how petite she still was, her butt feeling nice in my lap. We'd have to do this more often, I decided as I wrapped my arms around her waist.

"I can't believe they'd . . ." Susan paused, eyes losing focus.

"They'd what?" I asked, my heart still thumping with apprehension. I tugged her waist lightly to get her attention.

Soft eyes glinted, she grinned. "Those two . . . Those two . . . I mean blackmail? They're blackmailing me!"

"They're what?"

"Listen. They know we're having sex. They heard us last night," Susan said, blushing prettily.

I'd thought she'd been pretty loud.

"And, they threatened to tell Burt about . . ."

I interrupted, "They can't do that!" I exclaimed.

"Mark, shut up and listen," she said then paused and thought. "Remember when I told you how I dreamed about you when I was young?"

"Yeah, so what?"

"Keep that in mind. Olivia and Zoë threatened to tell their father unless . . ."

In the kitchen, Olivia and Zoë ate their cereal.

"So, do you think Mom will convince Uncle Mark?" Zoë asked.

Olivia's mind was buzzing, her imagination working overtime. Imagine actually . . .

"Olivia!"

"What?"

"Do you think Mom will convince Uncle Mark?" Zoë asked again.

"Yup. What choice does she have?" Olivia giggled. "I can't believe you threatened to tell Dad!"

"Well it worked, didn't it?" Zoë said with a grin. "Besides, it's only a little blackmail. We're not asking them to do something they aren't already." Her mind drifted as she imagined.

Both girls ate their cereal, minds occupied.

In my study, I looked at Susan. "You've got to be kidding me," I said.

"I'm not."

"But . . ." I exclaimed.

"Mark, I remember what I wanted at nine, at Zoë's age. And I definitely remembered what I wanted to do to you when I was twelve. So I can understand them. They're inquisitive."

"I can't!" I exclaimed, already feeling embarrassed.

Susan grinned. "Sure you can. Look, you've got an erection," she said, emphasizing her observation with a wiggle of her ass and clench of her buttocks.

Fuck, I did have an erection. "But, you're their mother! You can't agree," I insisted.

Susan's smile faded. "Mark, what choice do I have? If they tell Burt, I lose them permanently. Besides," she added, a smile reappearing, "I find this whole incest thing rather exciting. Don't you? Anyway, what harm can come? They only want to watch us having sex."

I liked Susan's grin. She was right; this whole incest thing was very, very exciting. "Come on," I said. "Let's talk to those two trouble-makers. We'll see how serious they are. I have an idea of my own." Susan grinned when I explained what I was going to do and, lifting her from my lap, took her hand and led her to the kitchen.

Olivia and Zoë tried to put on innocent expressions and failed miserably, their eyes twinkling with impishness and excitement. It made them very attractive, I thought. Smiling to myself I spoke.

"Blackmail? Honestly! You two are incorrigible. Are you really serious?" I asked.

They looked at each other, turned back and nodded, trying unsuccessfully for an innocent expression again.

"Okay. If you want to watch your mother and I, you'll have to be as naked as we'll be." I assumed they'd both be far too shy to be naked in my presence. I knew I had them when they both blushed. Except . . . I didn't have them. Before I could complete my sigh of relief, they both grinned, blushes and all, incredibly attractive, I thought.

"Okay," Zoë agreed enthusiastically.

Huh. All right then. "Come on, Susan," I said, pulling her over to the couch. Sitting together, I spoke to Olivia and Zoë over my shoulder as they sat at the kitchen counter. "Well then? Come on. Get over here and strip."

"Now?" Olivia asked.

"No time like the present," I answered. "Hurry up. Here," I pointed in front of me. Susan chuckled, settling next to me.

"In daylight?" Olivia asked, "Here? In the living room?"

"That's right. Come on. Hustle, hustle. I want to see you two naked." Suddenly, I actually did, too.

"Zoë might," Susan chuckled quietly to me, "But Olivia would never undress in the open like this. Very smart, Bro."

I smiled at Susan, and then noticed Zoë walk over and stand next to the TV in front of us, her lovely cheeks red with a blush, eyes glinting, and a shit-eating grin on her face. It was a damn-the-torpedoes look. She tugged her t-shirt off over her head to reveal a flat chest, two small pink areolae and tiny nipples. Her hair was a complete mess and, as she kicked off her sneakers and unbuttoned her jeans, Zoë stared right into my eyes, throwing me a challenge.

Susan watched her daughter undress and grinned when Zoë shoved her jeans down, so tight they pulled her red cotton panties down, too. Mark, holding her hand in his lap, tightened his grip as Zoë stripped. She felt him grow erect against the back of her hand. Jeez, Mark was aroused by Zoë's nudity. How interesting. She leaned over and whispered to him, "Zoë reminds me of when I was that age. I had my first orgasm dreaming of you when I was nine. Wouldn't you love to see Zoë play with herself?" She smiled when Mark inhaled sharply.

I could only nod, my eyes riveted on the sight of a nine-year-old standing nude, blush fading, eyes looking at me openly. Zoë had no hips to speak of, just bony protrusions, no flare. Her pussy was tiny yet large on her, curving out from her tummy in a lush, hairless, sensuous pad. Twin labia formed a tight cleft that seemed to fill the sexy gap at her crotch. My erection strained at the sight of her clit peeking out between her legs. Jeez, she was a sexy little thing.

I called out to Olivia, still sitting behind us. "You too, Olivia, or the deal's off."

"Come on, Sis!" Zoë urged, sitting on the edge of an armchair facing us.

Susan's hand tightened in mine. She smiled and spoke to Olivia. "It's okay, honey. You don't need to. Just go to your room."

"I will not!" Olivia exclaimed from behind, the threat of missing out too much for her.

I heard a scrape, heard shuffling. Olivia walked slowly into view to stand near Zoë, her face bright red, eyes cast down. She glanced at Zoë sitting naked, flashed a nervous smile at her then looked down again. Without looking at me she reached for the buttons on her blouse, opening them one by one, her hair a curtain almost hiding her face.

Susan leaned in to me and whispered, "I can't believe she's doing it."

I was so hard, my erection straining inside the jeans. Visions of Susan kept passing through my mind, the resemblance growing stronger with every button undone. I was holding my breath when Olivia slipped her blouse off revealing a small cotton training bra, white with tiny red roses and red trim, a small red bow in the center, and small barely pubescent breasts mounding the cotton seductively.

The back of Susan's hand pressed against my erection. She leaned close. "Does it remind you of someone?" she asked. I nodded. It did.

Olivia opened her jeans with a snap, the zip lowering loudly, and with a wiggle, lowered them over her small bum to fall to the floor, her eyes still looking down. My breath came out in a rush. Her matching panties conformed seductively to her little pussy, hugging it tight, a camel toe visible. I watched her take a deep breath and shove her panties to the floor before straightening.

"Jeeeesus," I whispered in awe. Olivia's pussy was exactly like Susan's at that age; full and plump, dusted with the first growth of dark pubic hair, thick rounded labia forming a seductive tightly closed little cleft, her clit, like her sister's, winking at me from between her legs. My erection strained.

Olivia had a delicate, attractive adolescent flare to her hips and tapering thighs that formed a sexy, sexy gap between slender legs. She was gorgeous; she was Susan just as I remembered her.

Her face came up, dark eyes looking at me, face blushing bright red. I saw her hands twitch as if to cover her pussy, then rise to unclip her training bra behind her back, her eyes boring into me as if daring me or something. She dropped her bra and watched me grip her mother's hand tightly. Olivia's breasts were stunning, absolutely stunning. They were petite, almost conical, and gravity-defying marvels of nature topped by small pink areolae and tiny soft nipples; pubescent perfection, intensely alluring. Olivia stood almost defiantly, her eyes observing me.

"Your turn," Zoë said to us, breaking the moment. "Way to go, Olivia. I thought you weren't going to for a moment."

Olivia smiled and sat next to Zoë.

My sister squeezed my hand. "So how do we do this?" she asked me.

"I dunno. I've never had an audience before. Hold on." Rising, I went over to Zoë, raised her chin and kissed her gently on her mouth, Zoë's eyes twinkling. I did the same to Olivia, causing another blush. "You're both absolutely gorgeous," I said, "Way too sexy." I found them intensely desirable, even more so when Zoë grinned at me, Olivia smiling shyly.

Back at the couch, I tugged Susan's hand, brought her to her feet, and started undressing.

"Hey! You've gotta turn this way," Zoë said loudly.

Both Susan and I turned as we stripped. I began to appreciate the thrill of displaying myself, my erection straining when both girls stared at it intently.

Susan turned me towards her, pulled me against her naked body, firm breasts pressing against me, my erection nestled into her silky stomach. She put her lips to my ear. "They want to see us having sex, so let's show them," she whispered heatedly, forcefully, arousal making her voice slightly husky. I heard a little of the firebrand sister I remembered in the tone of her voice. I loved hearing my sister's intense arousal. It thrilled and excited me.

We kissed, our kiss becoming very passionate very quickly, mouths open, tongues dancing. Susan manoeuvred me around as I caressed her sexy breast, ending our intense kiss with a slight shove. I fell back on the couch, slouched across its width, bum at the edge, my erection resting on my stomach.

Pushing my knees together, Susan turned, presenting her sexy ass to me. Standing, she straddled my lap. I watched her hand appear between her legs. She took my erection, lifting it up, nestling the tip against her moist pussy. She was incredibly aroused, her pussy warm and slippery.

"Can you see?" she asked softly.

"Just your ass," I replied as I reached for her waist.

Susan burst into a fit of laughter, her body shaking, pussy rubbing my tip. "Not you, you goof! The girls."

"Oh." Peering around her I saw Olivia and Zoë grinning, their eyes bright and staring at their mother's crotch nestled to my erection.

"I think those two . . . Jesus, Susan," I gasped when she suddenly sat on my rigid cock, her silky slippery pussy gliding down my shaft like a hot glove, two firm buttocks settling on my groin. When she gently clenched her vagina my head fell back, losing sight of the girls, my complete attention on the feeling of my erection buried to the hilt in a velvet paradise.

Zoë was the first to speak. She'd stared as Mom sank onto Uncle Mark's erection. Even with Mom's pubic hair, she could see Mom's slit stretched around his penis, her clit hard and red. Unconsciously Zoë cupped her pussy wondering what it felt like. "Mom," she asked, "How did you get it all in? How deep is it? What does it feel like?"

Susan was wrestling with how erotic she found the whole situation. She'd always insisted the lights be turned off when she and Burt had sex, her reaction to his scathing remarks about her body. She'd always been under the covers, too. Yet this situation, naked in daylight, her brother's erection buried up her heated pussy with her little girls watching, made her realize how exciting exhibitionism was. It was so kinky; very exciting.

She answered Zoë, "Come over here and feel," she said, her hand pressing to her lower stomach. "You too, Olivia." She felt Mark's erection flex inside her. "How ya doing back there?" she asked with a grin, squeezing her vagina on his thick cock.

"Fuck me," I gasped as Susan's pussy gripped me hard.

"Not yet," she answered. "Wait a moment and I will." She smiled at his groan.

As the girls approached, Susan took Zoë's hand and placed in on her lower stomach, just above her pubic bone. "Push here," she encouraged softly.

Zoë couldn't believe she actually felt Uncle Mark's erection inside her mom. "Olivia, feel this," she enthused.

Watching Olivia feel, she turned to Mom. "How deep, Mom?" she asked.

Susan pointed to a spot about an inch and a half below her navel. "Here. He's all the way in me up to here." She felt Mark's hands on her hips begin to move her back and forth, a spark of arousal charging through her as his crown rubbed her deep, her clit rubbing on his thick shaft.

Bending forward slightly, she held his knees and lifted herself off his wonderful erection, feeling every centimetre of it as it slid from her pussy. When the flared ridge of his crown oozed out of her, she sat back down hard, breath gushing out. Deep. "Uh! Good." She did it again, breath whooshing out when she felt her brother's erection thump against her cervix. Suddenly the whole situation was too much, too exciting. She needed to cum desperately, her pussy aching. She started fucking Mark, rising and dropping, fucking herself with his thick cock, so good Mark. Seeing her daughters staring at her pussy as she fucked her brother excited her even more; so damned naughty!

She felt Mark's hands on her hips, felt empty as she rose, beautifully full as she thumped down, pleasure blossoming, empty, thump down hard, full, pleasure. Fucking him, head bent, she started rubbing her clit furiously with a finger, pleasure storming in, her chest tight, areolae puckering, panting, God I'm fucking my brother.

Everything else faded leaving just the incredible sensation of her brother's erection pounding in deep. Her climax arrived with a bang, slamming into her. "Oh God . . . cumming," she gasped, her body jerking and shaking. She started trembling, froze, crashed down on his hard erection, her vagina cramping. Suddenly two hands reached around her, held her aching breasts, pulling her trembling body to lay back against him, her climax shaking her, twitching, legs clamping. She felt incredible pleasure in her pussy explode, her nipples ache. Humping, desperately rubbing her clit, she came hard, gloriously hard.

As her climax ebbed, heart pounding, she became aware of Mark's erection, still hard, still buried in her. She felt him wrap her in his arms and stand.

Rising, I easily held Susan's feather-light body. With my erection firmly buried in her from behind, I turned and knelt, placing her face down across the width of the couch, her knees on the floor. Grabbing her small waist, I started to fuck her, needing to cum. I was desperate, her writhing and clasping on me as she climaxed had driven me crazy. Holding her hips, I fucked her hard, shoving deep, my groin bouncing against her ass, withdrawing almost completely, shoving, fucking her. I felt my balls slap against her pussy, pressure build, fucking her, fucking my sister, climax approaching.

"Oh Jesus, Mark. Cumming again!" Susan cried out, spasms shaking her body, buttocks clenching. "Cum with me."

Her vagina clamped down. My climax immediately exploded, overwhelming me. With short desperate strokes, I fucked Susan hard, semen jetting into her with each glorious stroke, cumming hard, spurting deep into her pussy, fucking her, cumming, fucking her, cumming, God cumming. My climax washed over me taking my breath away before I collapsed on her perspiration-coated back, the final weak pulses of cum leaked into her snug pussy.

"Wow."

Pulling out of Susan, I glanced behind me. Zoë and Olivia were standing, expressions of amazement on their faces. But the sight that struck me hard was seeing them both cupping their pussies, and Olivia holding her small breast.

It was a strange Sunday. While Susan and I showered together, I asked the girls to get dressed and make lunch. Washing Susan's sexy petite body had me mentally horny again, though not physically; I was fucked out.

"Did you find that as exciting as I did?" I asked, soaping a seductive, full breast, paying far too much attention to a rigid nipple.

"More than you'll ever know," Susan responded as Mark's soapy hands caressed her breasts. It felt good to shower with him. She felt a tinge of embarrassment return. She'd seen both Olivia and Zoë grab their pussies as she'd fucked Mark and it had aroused her. In the depth of her climax, at the height of passion, she'd imagined Mark with both of them, remembering how she'd felt at their ages. It was so illicit it had shocked her at how erotic she found the idea.

She was discovering a side to her she never expected; a sensual and adventurous side. A kinky side, too. She decided she'd need to think about it some more. Reaching for the soap, she lathered Mark's soft penis up.

When we emerged, clean, dressed, me with another minor erection brought on by watching Susan put a feminine hygiene pad in her panties, "Still leaking your cum, Bro," my nieces were dressed and putting out sandwiches.

I went up to Olivia, held her chin gently, bent and kissed her soft, closed lips, loving the graceful blush that flowed into her face. I did the same to Zoë, amused with the sly grin she gave me when her tongue darted out to touch my lips. For a moment I was tempted to chase that exciting little tongue.

"So what did you make?" I asked, feeling quite hungry, staring at the sandwich.

"Peanut butter and banana!" Zoë exclaimed with enthusiasm.

"You've got to be kidding me! No way!" I objected.

With peals of laughter and scornful comments heaped on me, I threw the sandwiches in the trash and took everyone to lunch; a real lunch.

Throughout the afternoon, both girls kept looking at me or their mother. They'd giggle or smile when they spotted me holding Susan's hand, and I saw speculation in their eyes. I thoroughly enjoyed them, recalling how spectacular they were naked every time I looked at one or the other. I loved how Susan would walk close to me, her hip brushing against me occasionally. It felt good when she casually pulled my arm around her waist. Every time I kissed her lightly on her lips, the illicitness of it sent spikes of pleasure through me. I enjoyed the fact that everyone on the street could see but didn't know I was kissing my sister.

That night Susan lifted the sheet and slipped into bed after saying good night to her daughters, sliding across to me, her knee worming its way between my legs to rest against my balls.

"You're never going to believe this," she said softly. "Olivia and Zoë are blackmailing us again. This time they asked if they could have sex with you."

I was about to object. But I paused. Truth was, I liked the idea of sex with my nieces. I liked the idea of incest, and was excited by the prospect of sex with two little girls.

"I'll do whatever it takes for you not to lose custody," I said, trying to sound serious.

Susan laughed, reached down and grabbed my erection. "You're such a liar, Mark. You want to have sex with my daughters."

I grinned, "True. But, I'll only do what you want, not what they want."

She smiled. "You know what? This whole incest thing is so arousing, don't you think? And to be honest, the idea of you making love to my girls sort of turns me on." She reinforced it with a squeeze of my erection followed by a gentle stroke.

"Does it really?" I asked.

"Here," she said, "Feel."

Susan took my hand and guided it under her nightshirt. I shuddered when I felt how wet her pussy was. Jeez, she really was horny. I groped her, my finger slipping through silky moist labia. "Wow. It really does turn you on."

She let my erection go, leaned close, smiled and kissed my lips.

"Okay, girls! He's agreed," she called out loudly over her shoulder, giving me a mischievous grin.

Zoë charged through the door, leaping onto the bed and bouncing on the mattress. Olivia followed her, walking slowly, more sedately, trying to be more mature. She sat on the edge of the bed.

Susan leaned over Mark, whispering as she gently stroked his thick erection, "Olivia gets to go first. She's the oldest."

Rolling away to give Mark room, she called Zoë to her and hugged her closely. "Let's watch them," she said quietly into Zoë's ear, pulling her little girl's back against her. She caressed Zoë slowly, rubbing her flat chest, teasing her nipples into little beads, slipping her hand down to gently caress her daughter's hairless little pussy. She rubbed her aching nipples against Zoë's back, squeezing her thighs, her own pussy beginning to flush with excited arousal.

Zoë lay quietly watching Uncle Mark and Olivia. She parted her legs when Mom reached for her pussy to give her access, sighing gently when Mom cupped her, and closed her legs. "Mmmm. Nice, Mom," she whispered.

Olivia was shyly smiling at me, her pretty face red-cheeked. "Come," I said reaching for her.

Sitting on the side of the bed, I drew Olivia between my knees. I couldn't get out of my mind how she was so much like Susan at twelve, her perfect pubescent body that had shaped my lifelong definition of sexy. She was so petite in my arms, a slender girl, her little breasts so remarkably firm they hardly moved.

Reaching for her face, I cupped it, looking into her grey eyes. Pulling her to me, I kissed her, her soft lips pressing against mine. When she slipped her arms around my neck, I held her naked body, my hands caressing the curve of her spine from her shoulder blades down to the sexy, sexy out-sweep of her bum and the rise of twin buttocks. My erection strained when Olivia pressed against me, her arms tightening. "You're so damned sexy," I whispered quietly in her ear, fondling her twelve-year-old bum, my heart thumping, "So sexy."

Olivia moaned and hugged my neck. When I kissed her and touched her lips with my tongue, her mouth jammed against mine, suddenly opening, urgent, her little tongue emerging to press between my lips.

Holding her, I rolled back onto the bed, drawing her on top of me, her petite body pressing my erection to my stomach. She wiggled in my arms rubbing my erection with her soft stomach, her tongue probing at my lips. Olivia sighed and her body seemed to relax on top of me when I opened my mouth. I caressed twin mounded buttocks, small succulent hills that rose and curved spectacularly.

As I teased my fingertips along the crease of her bum, Olivia's legs fell to my sides and her tongue became active, thrusting into my mouth accompanied by another moan. Her little pussy was moist, aroused, silky warm dampness slipping across my fingers as I traced her slit feeling the tiny pubic hairs.

Memories of wanting to kiss Susan's pussy came back with a rush. "Hold on," I whispered, breaking the sexy kiss. Rolling Olivia onto her back, I scooted down, moving between her legs as she bent her knees, my breath catching. Olivia's pussy was stunningly sexy, a thick pad that mounded from her tummy, seemingly soft, dusted with little pubic hairs that emphasized how rounded and full her pubic mound was. Her pussy narrowed seductively with deep valleys on either side. Her pubescent cleft, formed by thick labia, was slightly parted. Cradled by sexy labia, I could see her long clitoral hood ending at the nub of her clit, half way down her moist slit.

As I pressed my erection to the sheet, I caressed her outer thighs, silky soft skin with fine hairs. Inhaling, I drew in her scent of arousal, arousal I could actually see. Below her clit, Olivia's inner lips were short, still not fully developed and below them, a hint of dark pink glistened, so sexy. Precum oozed onto the sheet when I kissed her sexy pussy, warm, soft and inviting. Her body twitched when my lips touched her soft yielding labia. Her hands reached for my head.

"Oh, Mom," she moaned.

Looking up, I saw Susan on her side hugging Zoë, a smile on her face as she watched me taste her daughter. A shudder passed through me. I saw Susan's hand at Zoë's groin cupping her daughter's pussy, such an arousing sight, even more so when I noticed her finger moving. Jesus, Susan was fondling Zoë.

Treating Olivia like the precious, delicate gift she was, I probed her slippery slit, tasting her arousal. She was delicious; a light ambrosia, the flavour of pubescence, a hint of musk. She was intensely exciting. It made my erection throb and precum leak as I humped the sheet involuntarily. When my tongue probed the tiny entrance to her vagina, Olivia groaned, curled her hips up to press me deeper, her silken thighs squeezing my face, her hands closing into fists, gripping my hair. Excitement made me lightheaded. Her vaginal opening was so small, and I was going to penetrate her. God Almighty, I was going to fuck her!

I heard my moan as if it was someone else's. Olivia's small clit was a hard nub and her plump labia hugged my tongue as I licked. Her hips moved gently rubbing her clit on me, small hands pulling my face to her crotch harder. She started undulating her pelvis when I sucked gently, rubbing her sweet pussy on my face.

"Oh, Mom!" she gasped as if surprised.

I drowned in the sensation of Olivia suddenly climaxing. It surprised me it was so sudden. She clamped her thighs against my head, her small body arching, her delectable pussy pressed hard against me. For a second she froze.

"Oh God, oh God!" Olivia writhed, pumping her hips, smashing her pussy to me. I sucked her clit as she climaxed, her body jerking. It was incredible, absolutely incredible.

"Stop! Please!" she begged, her hands pushing my head away, twisting her pussy away from my mouth.

Moving up, I gathered her shaking body in my arms and rolled her on top of me, holding her trembling body as the remnants of her climax passed, my erection straining with desire.

Eventually Olivia calmed. Her head rose from my chest, a smile forming on her face when she looked at me. Scooting up, she kissed me, lips smashing against mine bruising me. "Thank you," she whispered heatedly, her hands hugging me.

"Olivia, my darling," I said, "It was entirely my pleasure."

A different girl emerged. Gone was the hesitancy and shyness. Olivia started rubbing her tummy on my erection. Precum suddenly made her slippery, her stomach caressing my crown. Two small breasts pressed against my chest and I was in heaven as a naked twelve-year-old wiggled against me.

She pushed off my chest, rising to straddle me, my erection nestled against her sweet pussy. This Olivia, this new girl, reached down and started caressing my erection, spreading precum, her eyes staring at her groin. Reaching up I caressed two petite boobs, little breasts that were remarkably firm. I teased her nipples, rubbing and pinching until they grew hard. She gave me a heated look.

"I'm ready, Uncle." Rising, she held my shaft. I reached for her narrow hips, a small gap between the tips of my thumbs proving how young and small she was. She slipped the damp tip of my erection through her plump labia, rubbing me back and forth to spread slippery precum. My heart was pounding; the sight of a twelve-year-old poised above me was intoxicating. In Olivia I could see Susan at twelve and I desperately wanted her.

Olivia glanced up at me quickly when she nestled the tip of my erection to her entrance, one hand supporting herself on my stomach, the other gripping my shaft, holding it in place. I saw her take a deep breath, her head falling forward to stare at her pussy.

And I felt her. God, I felt her push down, her pussy pressing against my crown. She made no progress. Rising, she rubbed my erection around her opening in little circular motions as if to find the exact spot. Then she stopped. Holding my shaft firmly, I felt her push down again. I stared at her pussy, her labia bulging out, my crown filling her cleft, clitoris inflamed red. Blood roared in my ears when I felt Olivia's little vagina stretch slightly. She seemed to be pushing so hard. She eased off, pressure abating, pressed again, my erection stretching her slightly more. It was torture as she moved, slowly yet firmly, working herself onto my cock. It was exquisite torture feeling her vagina stretch, knowing I was soon going to be penetrating my twelve-year-old niece.

My world narrowed to the sight of Olivia trying to impale herself on me, her pussy stretched. Suddenly she cried out and a vice-like grip held my crown. She collapsed forward on my chest, her body shaking. I was in her, just. I had taken her virginity and she was painfully tight.

Holding her I waited for her body to calm, glancing across to Susan. My sister watched with concern, still hugging Zoë. Zoë's eyes were wide.

Waiting, I caressed Olivia's back and bum and thighs, enjoying the feel of her small body on me and loving the tight grip her pussy hand on my crown. Her body eventually calmed. I felt her testing the sensation of being penetrated, small clenches of her pussy. She sighed. "That hurt," she told me softly.

"Would you like to stop?" I asked, hoping desperately she'd say no.

She raised her head and gave me a shit-eating grin. "Are you kidding me? Stop? Now?" She reinforced her opinion with a little push back.

My eyes almost crossed when I slipped into her a little further, her small pussy gripping my erection hard her entrance now a ring on my shaft.

"Ooh. That's good," she sighed. Pushing herself up with hands on my chest, Olivia sat upright, my erection sinking into her tight pussy inch by inch. She worked herself on and off, gradually sinking down. I felt every bit, my crown squeezing into her, a tight velvet glove slipping down my shaft. Just as the tip touched her end, two buttocks settled against my groin. Olivia had taken me completely. I was buried in a twelve-year-old, held by a tight, hot sheath, her small pussy spread, labia stretched, her small clit rubbing my shaft.

"What's it feel like?" Zoë whispered to her sister.

"Full," Olivia whispered. She moved back and forth once, the tip of my erection rubbing against her cervix. "Uh. Oh! And goooood," she sighed, her eyes closing.

I held her small hips again when she started moving back and forth, rubbing her clit on me, buried in her, her tight vagina massaging my erection, the tip rubbing deep. She moved gently, just hips back and forth, back and forth, her hands on my stomach, head bent as she fucked me. Little moans escaped. And then she shocked me.

"Oh God, oh God!" she gasped. Her body jerked and I watched in awe as Olivia climaxed again, her body shaking and jerking. With a cry she pulled off me and collapsed on my chest, still jerking and trembling.

My erection was straining. I desperately needed release. But all I could do was hold Olivia until she calmed. Eventually two dark grey eyes peered up at me, a big grin on her pretty face. "Can we do it again?"

Rising, Olivia guided my erection to her now-slippery pussy, nestling it to her vagina and groaned as she impaled herself on it. This time she rose and fell, fucking me, her tight pussy clinging to my shaft, her clit rubbing. She fucked me in long slow strokes. My erection swelled, her little pussy so tight.

"Oh God!" she gasped. I was floored as she climaxed again, her body jerking and shaking as she fucked me. Olivia grabbed her breasts. Her body jerked. Holding her slender hips I fucked up into her tight pussy needing to cum.

"Stop! Stop!" she gasped, her body shaking.

It was agony. Buried inside her, wanting desperately to fuck her hard, I stopped, feeling her pussy clenching on my cock as she shook through her climax. I couldn't believe it, but Olivia was multi-orgasmic.

She calmed, bright eyes twinkling at me and started to fuck me again. This time I helped her, lifting her almost off, pulling her down, burying my painful erection into her twelve-year-old pussy. I'd been teased so much I needed to cum. Her pussy started clenching. She started gasping. I started sliding her pussy back and forth on me, desperate for release.

"Oh! Oh!"

Olivia froze, her body rigid. She cried out loudly, her vagina cramping hard, painfully hard. I felt dampness flood my groin as she collapsed on me, her body twitching out of control.

God I was so close it was agony, my erection swelling and pulsing. I felt Olivia melt on me, her arms slip off, legs falling limp. Glancing at her face I saw she'd passed out.

I should have stopped, but my need was too much, I was too damned horny. Holding her limp little body, I rolled her under me. Gripping her petite bum I start fucking her, short hard desperate strokes, pulling her small bum to me with each thrust. Her body jerked limply under me with each firm thrust. I fucked her needing to cum so much. Passed out, her pussy was still tight, slick, velvety, so arousing. I fucked her faster.

My climax rushed in. Curling her small bottom up, with my painful erection jammed against her tiny womb, ecstasy exploded. My aching penis released, semen burning up. With a deep, deep moan of pleasure cum spurted into her. I gasped, swelled, and another gut-wrenching spurt exploded, hot semen soaking my crown. In the grip of an intense orgasm, I held her petite body tight and fucked her, fucked her, fucked my twelve-year-old sister, firing cum into her, my body cramping, cumming, exquisite pleasure. I exploded again and again, semen flooding her tight vagina, desperately gripping her small bum, thrusting, spurting, thrusting, spurting, coming Susan, cumming!

Susan woke with Olivia stirring against her. She opened her eyes and smiled. "How are you feeling, honey?" she asked quietly.

"Sore. But, God Mom, it was incredible," Olivia said, smiling.

"Good. I'm glad," Susan said softly, caressing Olivia's hair.

"Can we get breakfast? I'm really hungry."

Susan glanced over at Mark. She smiled seeing him curled up on his side hugging Zoë to him. They looked so cute. "Okay. Quietly. Let them sleep," she whispered, bending to kiss Olivia's lips. She gave one glance back at her brother and daughter cuddled together before closing the bedroom door.

Movement woke me from a drug-like sleep. For a moment, in that between state, between dreams and reality, I thought I was hugging a twelve-year-old Susan.

Opening my eyes, I saw I was holding Zoë, her girlish, sleepy aroma filling my senses. Her compact little bottom felt very good against my groin; so good I started developing an erection.

She wiggled in my arms, turning to face me. I missed the feel of her buttocks against me, but loved the pretty face that peered at me.

She smiled; a shy smile. "Is it my turn?" she asked.

I smiled at her, hugged her and kissed her little lips softly, loving her sweetness. "Yes. If you want," I said.

"Yes, please," she answered, her sexy eyes large. God but she was attractive.

I expected the impish, bouncing, full-of-life Zoë to emerge. But it didn't. I was graced with a soft, slightly shy, seductive little girl who was full of love, warm and cuddly. Moving her onto her back, I pulled the sheet down, bending to kiss her.

It took some gentle coaxing, my thumb caressing her cheek, and my tongue touching her small silky lips, before I felt her mouth open and the tip of her tongue emerge. Zoë's soft eyes were watching me as she touched me, a smile curling her lips against mine. It was so sweetly sexy and became more so when she reached up to hold my neck with her small arms.

With care, I probed her small mouth and let my hand slip down to her chest, softly rubbing her nipples. When Zoë's little tongue pushed into my mouth I sucked it gently and my erection was complete, firm and pulsing at the eroticism of kissing my nine-year-old niece.

"Very sexy," I said softly breaking the kiss. She smiled shyly, so pretty.

Moving down, I kissed her nipples, pausing for a moment to suck them before kissing her diaphragm, her navel, and her silky soft tummy.

Zoë grabbed my head, pulling me up before I reached her pussy. "Please, Uncle," she said, "I'm ready."

My erection pulsed. Zoë took my hand and guided it to her little pussy. I touched her hairless mound, silky skin, a plump mound with a delicate little slit.

"See?" she asked, pushing my hand down further.

A shudder shook me. Zoë was wet, slippery and moist. She was aroused, ready. So was I, my erection straining. I probed slightly, shocked at how tiny her entrance was.

Spreading her legs more, Zoë tugged on my arm. "On top, please," she pleaded, eyes shining.

Rising, I knelt between her legs, staring at her sexy little body, a prepubescent goddess. Even with her legs parted, her tiny cleft looked small and almost closed, the tip of her clitoris peeking out at me, a dark shadow glistened with moisture below. My erection, jutting up, seemed huge, way too thick for her little pussy. Gripping my shaft I pushed it down, watching as the tip touched her hairless slit. Precum made me slippery, Zoë's labia bulging to the sides. I felt her clit, then saw it as I slipped down. I felt her pubic bone and suddenly, my erection was pressed at the base of her little cleft. My crown seemed to fill her groin.

When I looked up at her face, she was staring at me, an intense penetrating gaze.

I smiled, "Ready?" I asked, my heart now pounding hard.

"No." Zoë reinforced it by shaking her head back and forth.

"What's wrong?" I asked. "Do you want to stop?"

"No, Uncle. I want you on top of me," she said, "I want to feel you on top." Her small arms reached for me, a shy smile growing on her pretty face.

It was so hard to resist the urge to hold her non-existent hips and thrust. My erection nestled to her tiny vagina was so erotic, so arousing. It was hard to let go of the sight of my thick tip pressed against her hairless labia. The way the lips bulged as I pressed was so sexy. But it was Zoë's, my nine-year-old niece's first time and I wanted it to be special, what she wanted.

"Okay, Zoë." I sighed, lowering myself into her arms, feeling how petite her body was underneath me. I held as much of my weight off her as I could. She sighed.

"Yes. Like this, Uncle."

My erection slipped away from her pussy and down between small buttocks to press against the bed. Zoë moaned. On one elbow, I reached down and, after swiping the tip up and down a few times, repositioned myself, finding the slippery indent leading to her vagina, pressing forward slightly.

"Yes, there," she sighed, her legs wrapping over my thighs.

Lodged to her entrance, my erection was so hard I felt like I could penetrate steel. The contrast of having my cock poised to penetrate her with how small her body felt, so delicate and young underneath me, thrilled me. Keeping some weight off her by resting on my elbows, I held her slender shoulders, bent down and kissed her gently. "Okay?"

"Mmm-hmm." Her arms hugged my chest. She pulled.

I pushed carefully and felt my erection sink, but not penetrate. Easing up, I tried again, precum oozing into her with each hard throb. Zoë's legs tightened. "Relax," I whispered and suddenly the crown slipped into her tight, tight little vagina as she relaxed. She immediately gasped and tensed up at the pain. Her pussy clamped painfully on me. "Relax, Zoë," I gasped.

"It hurts," she moaned, her arms hugging my chest tightly.

Holding myself like that, my crown in a vice that seemed to be pulsing on me, was agony. We waited. I kissed her hair and inhaled her scent, all sexy little girl. My cock swelled and ached. I'd never felt anything so tight in my life. It would have been easy to cum just like that, not moving, just swelling and throbbing and filling her tiny vagina with my cum.

"Okay," she whispered, curling her bum up in encouragement, "It feels a bit better now."

Zoë was so petite, her hair tickled my chin. Arching my back, I bent and kissed her forehead. "Zoë, sweetheart, you feel amazing," I said softly. With micro movements I started fucking her, slowly, exquisitely slowly, working my thick erection into her young pussy, millimetre by millimetre, slipping ever deeper into her tight, tiny vagina. Every so often Zoë would murmur and, as precum lubricated her, my strokes grew longer. Over a period of minutes I stretched her tiny pussy, slipping deeper until, at last, I nudged against her cervix, all but an inch of my adult erection buried in her nine-year-old pussy.

"I'm in," I told her.

"I know. I can feel you, Uncle. I feel stuffed."

"Does it hurt?"

"No. Not anymore," she responded, moving her bum, pushing and pulling slightly. She clenched and giggled lightly when I groaned at the sensation.

Moving my body half off hers to the side, I reached down and slipped a hand under her to hold two beautiful, petite buttocks. It sent a surge of excitement through me. Holding her small bum reinforced just how young she was. Jesus, I was having sex with a nine-year-old and it felt incredible.

Pulling out of her in a long slow stroke, her pussy gripping me hard, Zoë moaned and tugged hard with her legs just as my crown emerged. I slipped into her deep, sliding through her tight velvet sheath to bump against the end. She gasped.

"Again. Do it again."

I started fucking my little niece, slow strokes, gripping her tiny bottom, shoving carefully, bumping into her cervix, swelling, withdrawing, fucking in again gently. Slowly our pace built, my heart thumping as I fucked her, pulling out gently, rushing back in, groaning at the erotic sensation of fucking a prepubescent girl, so petite, so tight, so deliciously tight.

Our pace increased, perspiration coated my back. Holding her tiny bum, I fucked her with more urgency, my thrusts gaining strength, Zoë's small body moving up with each thrust. I tried to hold off my orgasm, tried hard. But the sensations bombarding me were too much, fucking my young niece was too exciting, sex with a nine-year-old way too arousing.

Heaviness built, my erection swelled. "Oh God, Zoë," I gasped, "Gonna cum!" Shoving hard and deep, semen exploded, pleasure flooded me. Before I could breathe, I shoved into her little body again, a huge wave hit me, semen exploding painfully, bliss, cumming in Zoë! She bucked under me, her buttocks flexed in my hand. "Oh gawd!" she gasped and climaxed, small body heaving as I spurted forcefully, my erection swelling, thick semen erupting into her. I almost cried when her vagina clamped down on me. Pulling out of her I thrust in, Zoë's body writhing as I exploded, depositing another heavy load of cum deep into her little pussy.

All rhythm was lost. Desperate need took charge. Holding her tight, I fucked Zoë's jerking body in short strokes, spurting cum into her, bliss overwhelming me, cumming hard until there was nothing left, and still I heaved, stomach cramping, cumming into her so hard my toes curled, soles cramped, and stomach strained.

The all-consuming wave of bliss finally passed. Reality slowly reasserted itself. I felt Zoë's body trembling underneath me. Rolling off her, I gathered her in my arms, a sweet little lovable bundle. "Beautiful," I whispered. "That was fantastic."

She didn't even open her eyes, just hugged me tight, almost desperately. "Uh-huh. I love you, Uncle," she whispered.

A flash of colour at the door caught my attention. Susan stood in the doorway smiling.

"Sweet," she said.

While Susan took Zoë and Olivia out to the movies, I sat at my desk, focused on hacking into MasterCard. Burt had suffered a credit rating setback that would preclude him from buying a McDonalds on credit. And, as I made some changes to his MasterCard account, would now be unable to use any of his credit cards. They'd all been cancelled.

One hour later, Burt had eighteen outstanding parking tickets and a warrant issued for his detention. With that done, I composed an anonymous email to him, a little blackmail, routed it through two anonymous servers and shut my computer down. Burt's redemption was in his hands. Now we'd see how soon he'd blink.

Not long.

That night laying in bed, fondling my sister's spectacular ass, and contemplating how we'd have sex, maybe bent over the bed, her cell phone rang. Reaching to the bedside table, she answered, listening, her face growing more surprised by the moment. I kissed her perky breasts, fighting against her hand as she tried to shove my head away. "Okay. I understand," she said closing the cell.

"Who was it?" I asked as I caressed her lovely ass, my lips returning to stiff nipples.

"It was my lawyer. He said Burt just signed over custody, permanently, without even asking for visitation rights," Susan said with wonder, her hand caressing my hair.

When I explained the misfortunes that had beset Burt and the email offering to reverse all recent setbacks if he saw the light, just a little blackmail on my part, Susan started giggling then laughing loudly. In her joy I saw the firebrand sister of my youth return, her eyes sparkle. She was gorgeous.

Eventually Susan calmed down. She cuddled to me, so I took the opportunity to fondle her sexy pear-shaped ass again.

"Thanks, Bro," she said, rising to kiss me softly. She stared at me, contemplating, looking at me with love.

"I want to give you something I never gave Burt," she said with a smile as she straddled my waist.

"Give me what?" I asked, wondering, intrigued, reaching up to fondle her small boobs.

Susan grinned. Her hand gripped my shaft. "I want to give you my ass. I've never had anal sex. Would you like to try?"

I saw two pairs of eyes peeking in from the door. Grinning, I whispered to Susan, "We've got an audience."

She smiled, dragging the tip of my erection back through her pussy to nestle between her buttocks. "Both?"

I nodded.

"How exciting." Bending forward, she whispered into my ear, "Zoë wants us to move here and live with you." She pushed her sexy ass back against my straining erection adding, "We might have to, Bro. I haven't been using any protection."
