Sexy Stepsister Spy, Part 2

by eloquent delinquent

Kristin drew the wet finger back out. "I'll do it for you, Mina. I'll show you how I masturbate my ass. I'll get off for you, and I'm sure I'll love it."

"Yeah?" Mina's eyes sparkled.

"Yeah," Kristin replied. "But you have to do something for me first. I get to watch you."

The girl suddenly shied up. "Watch me do what?"

"I want you to show me how you squeezed your pussy, last night. Will you do that for me?"

"I guess so," Mina said, being coy, but really, she did want to squeeze herself again. It was like her pussy desperately wanted to be touched. And so, never breaking eye contact with Kristin, she reached down and cupped her hand over the groin of her pajamas, over her puffy wet pussy, and squeezed. Pleasure swept up from it like a wave, made her go, "Ooo," and wobble a bit on her feet. The feeling of her pussy in her hand was fascinating - she could feel the heat of it, her pajamas were getting wetter from the contact.

Kristin's mouth opened and she gasped in sympathy, watching her little stepsister's reaction. She said, "Squeeze it again."

Mina did, and the gush of sensation was a little stronger, better than before. She was a bit frightened by the intensity of it, part of her wanted to stop. But Kristin was here, she'd tell her what to do, she knew how to make it happen.

Kristin raised a hand, and made what looked to Mina like a slow, 'come here' gesture, saying, "Now do it steadily, like a rhythm. Can you do that?"

Mina nodded uncertainly, but did as she was told. It kind of unraveled her. Her eyelids drooped shut, her mouth hung open. The pleasure seemed to multiply, like she was drifting higher, and at the same time this funny knot was tightening somewhere inside, making it hard to breathe.

Seeing her heaving chest, Kristin asked, "How do you like it?"

"Uhnf, so good..."

"Yeah," she encouraged, sitting up on the toilet, cupping one hand over her breast and gently pinching her sensitive nipple. Her other hand drifted down over her tummy, settling in her thick, kinky pubes, slowly tugging her pussy lips upward, teasing herself, not wanting to rush. "What do you call what you're doing?"

"I'm, umm, I'm masturbating."

"Do you know what you're feeling?"

"I don't know, I don't know what to call it."

"You feel sexy."

Mina's eyelids fluttered, "Sexy..."

"Sexy is when you listen to your body, and it tells you to give it pleasure, like you're doing now. Sexy is when you see somebody else, and your body tells you that you want to give them pleasure." Kristin licked her lips, spread her legs. "It makes me feel sexy, watching you do that."

"Like you want to touch me? Like you want to masturbate me?"

Kristin nodded, but Mina was so lost in her sensations that she didn't notice. So Kristin asked, "Do you want to touch me? You can, if you want."

The 11-year old's green eyes opened about halfway, as if trying to rouse herself from a dream. She stared brazenly at Kristin's body. The tip of her tongue appeared, pink and glistening, and her mouth slowly widened into a smile full of lust. "I want to touch your boobie, the way you're touching it."

Kristin's body was electrified by her stepsister's growing desire and lowering inhibitions. She released her breast and pulled her shoulders back, presenting herself with a seductive pout. "Don't stop masturbating though, okay?"

"I won't," Mina assured, and shuffled a couple of awkward steps forward, hand still kneading her crotch through her jammies. Their toes nearly touched, and Mina was a little taller than Kristin sitting. Her new big sister looked up at her expectantly.

Drunk on the pleasure surging steadily out from her masturbation, Mina watched her free hand rise and close gently around Kristin's pert boobie. It was sooo soft, so warm. It was lighter than she guessed, for some reason she was reminded of pastry and its lightness. She gently squeezed it, felt it yield, and Kristin went, "Mmm," and looked down to what Mina was doing to her. She cupped that pretty boobie, stroked it, and ran her thumb over the stiff, rubbery brown nipple, surprised by its heat.

"Oh that's nice," Kristin gasped, looking back up. She reached out and cupped Mina's blushy face, almost like Mina was cupping her tit. Her little hand felt so good, it made her so horny knowing that her stepsister was feeling her up. She drew Mina's head down and closed her lips over the girl's.

Mina had never kissed anyone like this, and better yet, it was her stepsister! A burst of sparkly feelings went off in her head. Her hips rocked with pleasure. She pinched Kristin's nipple, and the older girl groaned against her mouth. It tickled. Mina drew back, stifling a giggle.

"Okay, now open your mouth a little and I'll touch your tongue on mine."

The giggle spilled out. "Really?"

"Yeah. It's grownup, you'll like it. Don't you want to kiss me again?"

Mina didn't reply. She just parted her lips and leaned back down, planting her open mouth on Kirstin's, waiting to see what she would do. At first they just kissed deeper, almost like chewing on each other, breathing each other's breath, and that made her feel that sexy way, like Kristin told her. But then she felt Kristin's warm soft tongue slide warmly over her own, and Mina just melted. When her stepsister's tongue drew away, she nervously extended her own into her stepsister's steamy mouth, and when she touched her tongue, Kristin responded, they tangled tongues together, tasting each other, it was... it was magical.

Although one hand continued to fondle her stepsister's luscious breast, Mina let go of her overheated pussy and placed her other hand on Kristin's smooth shoulder, and they kissed and tongued with appetite. Kristin's hand tangled in Mina's hair, holding her close, and Mina went lightheaded, lost in it.

Finally, Kristin came up for air, unbelievably surprised and aroused by the horny miracle her little stepsister was turning out to be. Their eyes met and they both laughed softly at what was happening.

"You were right," Mina breathed, "that was amazing."

Kristin glanced down. "You stopped masturbating."

"Sorry, I really liked kissing your tongue too."

Kristin's dark eyes shone in a sudden bright smile. "That's okay, so did I. Did you cum?"

"I don't think so? I don't know."

"Believe me, you'd know." Kristin wiggled her hips on the toilet seat - she'd been waiting for this. "You want me to show you how?"

Mina bit her lower lip, and asked, "How?"

Tossing back her hair, removing Mina's hand from her stimulated tit and opening her legs to her stepsister's greedy gaze, Kristin said, "I know you like watching me. So watch me and just do what I do. I'll help you."

"Okay. I guess so."

"Well first, let's take care of this," Kristin said, reaching out and tugging Mina's pajama bottoms down. Mina's hand shot back up to her mouth nervously. The flannel crumpled in a heap around her ankles, and the 15- year old got her first look at her stepsister's pussy, bare, puffy, slick and glowing pink from all the excitement. It was beautiful, a ripe little fruit full of juice. "You want to be able to touch your little peach."

"Pussy," Mina corrected,

Kristin chuckled. "Pussy." She lifted her knees, tipped her hips and got her hand in position. She made sure Mina was watching, which she shouldn't have worried about. Mina was focused on her little pink morsel. "Take your middle finger and start just by running it up and down your slit, like this," and as she demonstrated she felt the wild pleasure pulse out from her happy pussy. But she couldn't lose control. Not yet.

She watched Mina emulate her. "Slowly," Kristin said, "Really feel it. Get it nice and wet."

"I'm already really wet. I think I soaked my pj's."

"Mmm, you are a bit of a slut. In that case you're ready. Take your finger and feel down to the soft little hole there. That's your vagina. Do you feel it?"

Mina's eyes unfocused for a second. "Uhm. Yeah."

"I'm gonna slip my wet finger into my vagina, and I want you to do it too. The deeper you go, the better it feels. But if you bump against anything or it smarts, stop pushing. Ready?"

"Yeah, I wanna."

"Okay, do it with me," Kristin said, and with Mina serving as a kind of erotic mirror, she felt her finger slip into her over-excited canal, crying out to be fucked. But she kept it still, watching her little stepsister as she delicately inserted her own finger, gradually, her face washing with surprise and pleasure, until her palm bumped her mound.

"It's all the way in," Mina gasped.

Kristin grinned. All that soccer must have broken her in early. "How does it feel?"

"Oh my god."

"Now, move your finger in and out, like this," Kristin said, starting to stir her honeypot, and watching Mina's excitement as she explored her cute little pussy only enhanced the hot thrills racing from her own. She couldn't resist speeding up, she needed it. "Feel with your body, go as fast as you want, find a rhythm, like you did through your jammies."

Mina copied her sexy stepsister at first, but soon she felt what Kristin had described, and her body started moving kind of on its own, pushing, swaying. As she satisfied herself, her eyes fell shut, despite how much she wanted to keep looking at Kristin's fingers going in and out of her pretty peepee. And she drifted into her own climbing pleasure.

Kristin noticed Mina's head loll to one side, blonde hair sweeping across her face, and knew that the 11-year old had found her sweet spot. She could masturbate watching her little stepsister's sexual discovery all night. She loved the amateurish way her thighs, her butt, and her lean tummy all twitched, instinctively driving her cunt onto her fingers. Kristin was getting close herself, but when she heard Mina's sighs start to turn to whines, she knew there was something more she could teach her.

It was getting difficult to think clearly, but she whispered, "Mina. Mina, do what I do, okay?"

Mina opened her eyes, nodding dazedly. She watched Kristin withdraw her fingers from her vagina, and slide them a little ways up. They were so shiny. She realized Kristin was breathing hard, her hips moving up and down, her little tummy clenched. She followed her big stepsister's lead, feeling the frustrating clench of her own vagina when her finger came out of that lovely slippery place.

"Up at the top of your pussy, under a little fold, there's a bump. That's your clit, that's your cum button. Find it, and then, rub it... uhhhhnn, yeah rub it." Kristin started massaging hers, eyes half-lidded, eager to see how Mina would respond.

It took her a minute of feeling around to find what Kristin was talking about, but once she touched it, there was no mistaking it. Super luscious feelings fired right into her middle, it was so sensitive she barely had to touch it, and her legs shook. She saw how fast and hard Kristin was doing it, but she just kept moving one finger back and forth across it, and it made her sexy sexy sexy. Her hips thrust against her finger, her belly got tighter and tighter, and there was this descending, pressing feeling down there in all that pleasure, like she might wet herself, and she felt panicked but she couldn't stop now, couldn't stop.

"I think I'm gonna pee," Mina gasped, scared.

"Rub it, go ahead and pee, rub it you little slut."

But she didn't pee. Instead, this sudden bursting pleasure erupted from her pussy and climbed right up to the top of her head. She felt her thighs clamp around her hand. She couldn't control the way she bucked, or the loud noises that came out of her, but she didn't care. This feeling, still pulsing happily inside her, was better than anything. Whatever she had to do to get it, that was okay.

Kristin saw Mina hit her orgasm and forgot about herself and her own desires, her finger slowing to a stop on her clit. The 11-year old was so beautiful, trapped helplessly in the throes of her first cum, her head dropped back and wailing, legs quaking around her hand and sweet little puss. The 15-year old slipped off the toilet onto her knees and wrapped her arms around her little stepsister as she shuddered her way down from climax.

Mina felt her stepsister hugging her and felt more loved, more accepted, than she ever had. Kristin had shown her the secret to the most naughty, grownup thing, and promised to show her more. How would that feel? She could barely wait.

Her arms were pinned and she could barely think, but she managed to breathe out, "Thank you Kristin oh my god thank you."

Kristin kissed her neck and chest, and after a few moments, Mina squirmed her hands free and opened her eyes, smiling. "Is that what you wanted to see?"

"Oh yeah, sweetie, I wanted to see you cumming." "It's soooo good. I can see why you wanna do it so much."

"I do. I have to." She leaned back, holding the girl at arm's length. "You want to see me cum now? You want see me do it in my ass and cum?"

Mina's eyes got big and she could only nod eagerly.

Kristin found her wadded up nightshirt on the floor and stretched it out on the tile floor, then moved her knees onto it. She pointed at Mina's pajama bottoms around her ankles and pouted, "I need a pillow."

Mina stepped out of them and Kristin drew them under her head as she leaned forward, her butt high and knees wide apart, head down on its side on the fragrant jammies, looking up at Mina. "Ready?"

The girl kneeled down to get a better view. "Ready."

Kristin reached back with both hands and parted her cheeks, displaying her tight pink asshole to Mina. "This is your naughty hole. No one tells you that it can make you feel good, but it can. It can give you the best, dirtiest feelings if you want it to."

With that, she brought one hand down and out between her legs, slipping two fingers lazily through her soaking cleft. Then, as Mina looked on in amazement, Kristin reached a little further and wiped her fingertips on that wrinkly sphincter, making it gleam with juice.

"First, you have to get everything really wet, it's so tight." And she brought her finger from her ass to her mouth and started licking it with total abandon. Honestly, Kristin was so horny now she could barely control herself, she tasted her own ass and it only made her want it more. Mina saw drool run down her stepsister's hand and drop to the tile. Then she reached around again, running that dripping finger down the groove of her ass til it rested on her rosebud.

It gave the 11-year old a funny feeling in her own butt as she watched Kristin push her finger in there. It's like she started warming up again, only this time it started in her bottom and spread to her pussy. Her face blushed, and she stared, fascinated as that finger began moving in and out, like it had in her vagina, only it must've been even stronger, because Kristin's whole middle flexed, arching and humping, in time to that one little finger that seemed to control so much. The naughty hole must be as good as the pussy, she thought.

And Kristin watched every horny emotion cross her little stepsister's face as she fingered her tight, dirty asshole. God, she felt like such a wild whore, and she loved it. Since she delayed before, her orgasm was rushing up twice as quick and strong as the first one, she wasn't even gonna have to rub her pussy and it was still gonna be crushing. She felt her body winding up, that lightheaded sensation of being completely in her body, and her free hand drew up to her head, grabbing the pajama bottoms beneath her and jamming that damp crotch right into her face. She was gonna cum, she sniffed the flannel and smelled Mina's sweet yummy pussy and her finger was deep in her ass and Mina was watching her be so dirty and she was gonna "oh yeah oh yeah oh fuck -"

Mina actually flinched back as Kristin started cumming, her big stepsister shook so hard, pushing her face into Mina's dirty wet pajamas, but it barely muffled the sounds she made, these long, ecstatic wails. Then she went from shaking to convulsing, her tummy flexing like before, only faster, sharper. Kristin's finger shoved in and out of her butt even while she was cumming. And suddenly, one, two, three little squirts of pee shot out of her pussy. Kristin's cries turned to deep groans, and her body slowed, her knees spreading slowly, relaxing.

Mina looked from Kristin's happy, relieved face to all of the sexy backside facing her. The little splashes of pee on the floor intrigued her. Had Kristin done it on purpose, or had it been like the feeling she'd had herself before her cum, only stronger? Was peeing normal?

She watched Kristin pull her finger lazily from her butt hole. And like before, the 15-year old brought it straight to her mouth and sucked on it blissfully.

Without really thinking about it, Mina extended a finger of her own to Kristin's dark curly pubic nest. She gently retrieved one of the amber droplets of pee hanging there, and put it into her own mouth, sucking on it, sampling it. It was bitter and salty, but not so different from those vinegar and sea salt chips she liked so much. Tasting your pussy and your ass was actually a lot better than Mina had imagined. Like cumming, it made more sense once you'd done it.

Kristin opened her eyes while Mina was reaching out for another drop, she felt the girl's finger brush her pubes, and felt a perverted joy seeing the contented look on her little stepsister's face as she sucked on her pee.

"Is that good, Mina?"

"It's kinda nice. It feels naughty, doing it."

"It is naughty, but you're a naughty little slut, aren't you?"

Mina took one more drop, popped her finger into her mouth, and nodded as she sucked.

"I'd love to taste your pee," Kristin said, suddenly inspired by a wicked thought. She twisted into a sitting position on her nightshirt, feeling her pleasured asshole throb as she settled onto it. "Would you pee for me?"

The idea of peeing in front of somebody else made her feel a couple different types of funny. "I don't know. I don't know if I can, with you here."

"I bet you can. I bet I can help you."

"How?"

"So you'll try?" Kristin sat forward, smiling, and Mina couldn't help but share in her excitement.

"Sure, I guess."

Kristin got to her feet, and Mina followed. "Let's get rid of this," the 15-year old said, grabbing the hem of Mina's pajama top and pulling it up over her head. "I wanna see you naked."

Mina giggled, "Okay." As the top came off, Mina felt a little giddy while her big stepsister stared admiringly at her. It was so wonderful to have someone look at her naked, it made her feel sexy and naughty.

"Come on," Kristin said, taking her little stepsister by the arm and leading her to the vanity.

"What about the potty? Shouldn't I be there to pee?"

"I can't help you as well there," Kristin replied simply. "Come on, climb up. I want you to pee in the sink. I want you to look in the mirror and watch yourself pee."

Mina looked doubtfully at Kristin even as she swung a leg up onto the counter, "I don't know..."

"You said you'd try," the 15-year old countered, and she helped little Mina up, touching her lean soft body for the first time, and now that she was nude Kristin was struck how childish her body was, even though her desires, her hunger for pleasure, seemed as strong as her own. Just like I was, she thought.

Slyly fondling Mina as she went, Kristin arranged the young girl into a squatting position over the sink, facing the mirror, her upper back pressing into the older girl's breasts. Kristin drew Mina's blonde hair back behind her ears, gathering it at the back of her neck, stroking a bit to soothe the anxious face she sees reflected back at her.

Mina was a little bit stunned, seeing herself naked and sitting on her heels, arms locked and supporting her from behind, knees spread wide and almost touching the mirror. Her little nipples were super hard and she could see the rosy blush on her face. She could also see her own peepee, almost all of it, the smooth, puffy pink lips and the deeper slick pink of her slit. It seemed only fitting to her that she was getting such an intimate look at her own privates at the same time she discovered how good touching them could feel.

She felt Kristin's warm chin rest on her shoulder and glanced up from her pussy to see her big stepsister's grinning face in the mirror beside her own. Conspiratorially, she murmured into Mina's ear, "Do you think you can pee for me now?"

"Maybe. I didn't pee before bed 'cause I was so excited, but..." Again the girl's face clouded with doubt, "This is just so weird."

Kristin gave that cute pout again. "You spied on me doing it. It's only fair."

"I know..."

"Do you want me to help you now?"

Mina just nodded gratefully.

Kristin reached carefully around her squatting stepsister and turned on the tap, just a trickle dribbling into the sink. She whispers, "Close your eyes and listen to that, think about how nice it'll feel when you pee, when you let it out of your body."

With her eyes shut, Mina felt her bladder responding sympathetically to the running water. She could feel the urine descending inside her. But she was also painfully aware of Kristin's presence close to her, of how naughty this was, and her little pee hole quivered, holding it back. This went on for more than a minute, and the whole time she could hear Kristin's breathing, excited, expectant. She tried to force it, but that only made the quivering stronger, making it even more difficult even as the need to pee grew urgent.

She opened her eyes and looked pleadingly at Kristin.

"Do you need more help?"

"Uh-huh."

Kristin chuckled softly and kissed her ear. "I hoped you'd say that."

Mina watched the 15-year old wetly lick her fingers, then her hand disappeared and suddenly Mina felt her stepsister's fingertips gently brushing her little pussy lips, barely touching them. After a few seconds, she felt the pad of Kristin's thumb come firmly to rest on her butt hole. Mina's eyelids flickered and her mouth pursed, "Oh. Oh Kristin."

The little touches kept up, dancing and tickling, maddeningly sweet, while Kristin's thumb massaged in little circles. Her need to pee was even stronger, but all the pleasure down there was getting her wires all crossed.

"Are you masturbating me?"

Kristin put her lips to Mina's ear and whispered, "I'm helping."

In an agony of conflicting needs, Mina squirmed under the steady teasing of Kristin's fingertips. Her touch was terribly expert, driving the pleasure from her pussy and butt higher and higher, while also making her need to urinate grow desperate. Her head fell back against Kristin's shoulder, each panting breath punctuated with a groan, "Ahh, ahh, ahh, ahh..."

"Let it go, Mina, it's okay, let it go..."

What happened next was such an overwhelming burst of feelings, Mina couldn't be sure if she was peeing or cumming or both at once. It didn't matter, it was so super beautiful. She squeezed her eyes shut tight, and over her own joyful whines she heard the hiss of her pee. She could feel it jetting warm and pleasant out of her, the intense relief mixing with the pulsing of her pleased pussy.

She felt hot urine splatter her ankles and her eyes shot open in alarm. She saw the yellow stream of her pee splashing all over the faucet and sink, even spattering the mirror. She saw Kristin's hand appear between her legs and interrupt the flow, causing pee to rain on warmly on her inner thighs. Her big stepsister got a gratified look on her face and moaned.

Then the hand drew back and Mina felt the slick hand on her butt cheek, supporting her. "Put your hand in, sweetie," Kristin purred, "Touch it."

Mina loosed an arm and reached into her own stream. This was so dirty, but she couldn't resist anything Kristin told her to do. The rush of hot pee drenched her palm instantly, causing the urine to spatter back onto her mound and her tummy. She could feel it dribbling into her navel. And as the stream began to weaken and splutter, Mina remembered what Kristin had done, took her pee-soaked hand and smeared it across her chest, rubbing it into her already slick belly. Kristin looked on with lusty approval. "Mmmm, that's it. So good, isn't it?"

The 11-year old's curiosity got the best of her, and she slid two pissy fingers into her mouth and sucked on the briny flavor. Looking at her stepsister in the mirror, she went, "Mm-hm."

Kristin reached her own hand around and slid it all over Mina's slippery torso, breathing heavily, rendered uncontrollably horny from the display. She eased the girl's slim butt to the counter, using her freed hand to pull the girl's blonde hair up. She leaned in and began to sloppily kiss and nibble Mina's neck while she continued wiping the girl's pee into her silky skin.

With all the sensual attention she was getting from her pretty stepsister, Mina's arousal didn't fade like it had, after she'd had her first cum. Her little peepee just stayed so wet and happy and made her eager for more. Is that just how it happened? Was she turning into a little slut? She hoped so. She wanted to be a little slut for Kristin. She sighed from the loving touches and kisses she received.

Kristin could feel that Mina's hips were still gently rolling, instinctively seeking more pleasure, which made the 15-year old dizzy with lust. She blindly reached out and grabbed a folded towel from the pile at the far end of the counter, setting it down right next to Mina. She ran one long swipe of her tongue up the girl's neck to her ear lobe, and murmured. "You're a mess. We've got to clean you up down there."

Mina nodded absently, turning a little and reaching for the towel. Kristin took the girl's hand and shook her head. "Turn around and sit on it. With your legs over the side."

In a happy daze, Mina trustingly scooted onto the towel, which was very close to the edge of the counter. She was glad to see Kristin there, kneeling, to keep her from slipping off. She placed the back of one knee over each of her big stepsister's shoulders, letting her feet dangle, heels gently bumping the small of Kristin's back.

Mina grinned and reached out, affectionately combing her fingers through her stepsister's short black tussle of hair. The older girl smiled brightly back. Glancing over to the potty, Mina asked, "Can you reach the paper or..." Kristin shook her head slowly, and unexpectedly Mina felt her big stepsister's hand pushing on her tummy, forcing her to lean back on her elbows, her head bumping the mirror. At the same time Kristin was rising a bit, lifting up Mina's thighs as her dark head leaned in. Mina felt her stepsister's breath on her peepee and got hot with excitement. What was she doing?

The tingly, smeary, melting sexy in her pussy inundated Mina's body and brain before she even realized that it was Kristin's mouth doing it. It was her wet nimble warm tongue that was fluttering all over her slit, slipping into her tender vaginal entrance, tickling her swollen lips, then lapping wildly at the bud of her clit. This last sensation immediately drove Mina sexually crazy, gasping and crying out as she spiraled up toward more delicious cumming.

Sensing it, Kristin grabbed Mina's thighs and pushed them up and back, exposing the girl's sensitive asshole. Sliding one hand up and around her little stepsister's leg, she lapped her way down Mina's juicy, yummy slit to her anus while her hand settled on the girl's smooth little mound. Kristin used her thumb to delicately lift the fleshy hood from Mina's clit and began to firmly rub it in little circles. As the girl squirmed in joy, Kristin began licking her sweet little virgin asshole with slobbering enthusiasm.

Mina writhed on the counter with delight. She never imagined anything could feel as good as she did right now. Knowing it was Kristin eagerly putting her tongue on her messy pussy and her dirtiest, most private place, filled her with a kind of love. It was all too much, and this time, Mina felt her cum racing toward her, rising up in a wave she was helpless to resist, and didn't want to. She clutched Kristin's short dark hair, holding her there while it rose up and up, going, "Oh my god oh my god oh my god ohmygodohmygod -"

Kristin had to push down on Mina's mound to keep her from thrashing away from her touch. Her little stepsisiter's back arched convulsively, again, again. She felt the girl's thighs shuddering, and against her tongue she felt Mina's anus pulsate with strong little contractions. She couldn't do anything about the cries of mindless joy that echoed off the bathroom walls, but frankly, she loved hearing them.

As Mina came down from her orgasm, Kristin lovingly kissed her puffy lips and mound, stroked her sleek, sweaty thighs. Eventually, the 11-year old raised her head, hair draping all around her face, and cupped Mina's cheeks, lifting the older girl's head from her tingling crotch.

Mina began giggling, out of sheer happiness, and Kristin joined her, as they looked at each other with amazement.

Kristin joked, "How did you like my tongue bath?"

"I loved it sooo much. But I don't think I got any cleaner." In fact the sweat and drying pee made her feel sticky. "I think I need a real bath now."

Kristin nodded. "You liked me in the shower before. How about one of those?"

"Okay."

Kristin helped a slightly sex-woozy Mina to her feet, and they crossed the room to the tub, the older girl following a couple steps behind the younger as she looked hungrily at her pert, childlike body and the delectable tan lines around her shapely little ass. Unnoticed as Mina slid the smoked glass door open, Kristin dipped her hand between her own legs and massaged her demanding little pussy, easing its urgent needs, but she knew it was only for a moment. She knew as she slid the door shut behind them she'd have to cum at least once more before this was over. This was better than anything at St Bernadette's. This was the sexiest night of her life.

Mina bent down by the faucet and ran a little water through the tub spout, just a trickle, testing it as it warmed up. The sound of the water, the tart smell of urine in the air, and what she'd already seen all came together in Kristin's body and a lewd thought seized her.

"Mina, I wanna pee, I gotta pee, I wanna pee right now..."

The 11-year old swiveled around in her squatting position by the faucet, not rising. She saw Kristin brace her feet against the edges of the tub, assuming a kind of straddling position before her. The older girl gripped her black bushy mound and eased back the lips, lifting her pelvis at the same time. And, eyes clouded with desire, she whispered, "Mina, please, please."

Mina moved slightly forward and got on her knees, lowered her arms, presented herself. She tilted her chin up and said, "I want you to."

Kristin slowly licked her lips as she felt her bladder yield. She watched in near disbelief as the stream of her pee gushed from her pussy and, gaining force, struck Mina's tummy, splashing and spattering onto her own feet. Mina gasped, it was so hot against her tender skin, so naughty to let Kristin pee on her. The arc of urine climbed, and when it reached the young girl's flat chest, she ran her hands through the stream, rubbing the warm fluid into her skin, smearing their pee together.

"Oh Mina, you're so awesome," Kristin groaned, the erotic feel of piss still escaping her.

The girl's huge green eyes lit up, and she quickly closed them and dipped forward, dousing her face and hair in her stepsister's streaming pee. As the flow diminished, Mina stuck out her tongue, catching the salty urine on her tongue and swallowing it. Finally, Kristin's pee dribbled to a stop, running down the inside of her thigh. She'd never done that to anyone before, and was stunned by how horny it made her.

Mina edged closer on her knees, wiping the piss out of her eyes she looked up at Kristin from almost between her legs. She said happily, "I'm a little slut."

And without hesitation she leaned forward, opened her mouth as if to kiss, and put her mouth on her big stepsister's dripping peepee. She felt crazy and she just started licking it everywhere, so excited to be tongue-kissing Kristin's best secret spot. She found herself loving the taste, not just the pee, but Kristin's other wetness, her tangy, earthy pussy flavor. She grunted and blindly ran her tongue through the folds of the 15-year old's delighted slit, eagerly trying to taste more.

And then she got a nasty idea. She saw Kristin do it to herself. Why couldn't she do it to her, too?

Kristin could do little more than groan and shudder. Her bratty stepsister had become a completely wanton little sex maniac, exciting her more than any other lover she'd ever had. This was her first for everything, but she was a natural slut, and Kristin relished every new perversion that Mina would unquestioningly accept. She even loved the sensation the girl's clueless lapping was creating in her pussy, a kind of unintentional tease that left Kristin shifting her hips to get the pleasure she was craving.

But then she felt one of Mina's pee-soaked fingers rub all around her asshole and then slip up into her tight tender sphincter, and decided she must know a little of what she was doing, because it was perfect. Her finger was tiny, but Kristin's anus was tight, and Mina thrust it into her with gusto.

She touched Mina's pissy hair and gasped, "Sweetie, my clit. Remember where it is? Do my clit now, my clit." And Kristin's head went slack as the 11-year old immediately obeyed, adjusting the wet, lapping pleasure right where she needed it. And between the Mina's passionate tongue and the eager finger-fucking she was giving her asshole, the horny 15-year old climbed straight to heaven, her orgasm rolling through her in huge, blissful waves.

Kristin dropped to her own weakened knees in the tub, kissing Mina hard, pushing her tongue iinto the little girl's mouth and tasting her own pussy and piss, enjoying the feel as the girl's hands roamed unabashedly all over her body. They nuzzled and stroked for a while, basking in each other.

Parting, Kristin turned on the shower, and the two rinsed luxuriously in the warm, heavy rush of the water. They handed each other the body wash, but after a moment of watching each other lather themselves, they were right back at it, soaping each other up in the most arousing ways possible, hands gliding over sleek firm flesh, kissing and giggling. Soon, Mina was licking Kristin's nipple, while her hands soaped diligently, one over the 15-year old's pussy and the other down the groove of her ass.

Unbearably horny and not to be outdone, Kristin roughly turned Mina around and bent her over, so her hands and forearms supported her against the shower wall. Running a lathery hand all over the girl's tight little white butt, she asked, "You want me to masturbate you? You want me to do it to you?"

Looking back drowsily over her shoulder, Mina sighed, "Yeah, Kristin, do it."

Kristin considered the aroused little body before her. She rinsed one hand and brought it to her mouth, licking and drooling on it to get it nice and slick. She took that slippery finger and slipped it gently into Mina's vagina, marveling at how tight it was, even for just one finger. Mina groaned happily and lifted her hips, presenting her adorable little asshole just in time for Kristin to bend over and push her face between Mina's firm white cheeks.

Mina gasped and tossed her head at the intensity of this double sensation. Her stepsister drew the finger slowly out of her pussy, and when she started to fret because it was almost out, she felt the tip of Kristin's tongue teasing all along the groove of her little butt, exciting her in a whole new way. Kristin slid her finger gratifyingly back into her tight vagina. But at the same time as that finger was returning, the tongue on her ass began licking right on her super sensitive butthole. She soon felt it forcing its way in, actually opening her anus and licking inside, but the finger pleasing her pussy was withdrawing.

It went on this way, one finger entering her vagina while the tongue went back to teasing her ass, pinning Mina's pelvis in ecstasy. Kristin built up the rhythm, violating her stepsister's ass and vagina with increasing passion. Mina was wailing steadily, out of her mind with lust, her tummy straining to thrust her hips back into those glorious fingers, that wonderful mouth. She couldn't think anymore - sunbursts of pleasure went off behind her eyes, obliterating anything but what her body felt.

When she started cumming, it felt like it just grew out of the intense joy she was receiving, just so much more, a great blossom of amazing feeling opening from between her legs, enough to wipe her out. She didn't realize she was crying out, "Oh, yes! Oh, yes!" the whole time. She barely cared when she slid down the wall and collapsed in a wet, soapy heap, her hips still twitching.

It wasn't til Kristin bent down beside her, kissing her shoulder and stroking her back, that Mina felt like she was done cumming. Her big stepsister helped her up and sensually rinsed her off, paying extra attention to her hard little nipples. Mina chuckled dreamily, pawing at her big lovely stepsister, goofy with joy.

Kristin thoughtfully sluiced water over Mina's body, wondering if she could get the exhausted girl to give her one more cum, or if she'd have to take care of it herself. And if so, if Mina would like to watch, maybe on her back while Kristin straddled her face. But then she had another thought, the aroused teenager's mind immediately turning to the perverse. "Let's go, little slut" she said, shutting of the water and sliding open the door.

Floating limp on a cloud of naughty joy, Mina gladly obeyed. She was aware of her big stepsister arranging a towel on the floor, and was grateful when Kristin had her lay facedown on it. Her body revived more fully as Kristin gently wiped her dry with another towel, shifting her body and stroking each part thoroughly, coyly stimulating her, murmuring how sexy she is, what a good little slut she is. And she came all the way back when she felt Kristin ease her ass cheeks apart, and experienced the sensation as her sweet, deft, wet little tongue began exploring her tender behind again.

Oh, she loved it, the gentle dirty licks and then the firm feel of Kristin's tongue pushing up her butt hole, making it feel so good, and knowing that it was Kristin doing it, worshipping her dirtiest part just to make her get the sexy feeling... that was the sexiest feeling of all.

As she continued tonguing Mina's ass, the 11-year old rose up onto her elbows and looked back over her shoulder at her beautiful, naked stepsister, bent down over her, nuzzled into the crack of her bottom, eyes sweetly closed as her mouth did its naughty work. "Oh Kristin. That's so amazing. I'm feeling sexy again."

With a last soft kiss down there, Kristin raised her head and grinned affectionately. "You are sexy, so sexy. You make me feel sexy, too."

Mina closed her eyes and blushed. It wasn't til she opened them again that she noticed that her stepsister's hand was down between her legs again, and that her shoulder was rolling steadily, gently.

"Are you masturbating?"

Kristin nodded and rose up into a kneeling position, showing the 11-year old her fingers rhythmically sliding up and down her pink slit. "I'm like you. I can't help it."

"I love watching you be naughty," Mina smiled. "That's why I had to spy." she reached down her own back and lightly rubbed her own butthole. Kristin had made it all wet and slippery, it felt good back there.

"Taste it."

In total obedience, Mina brought her finger from her ass to her mouth and inserted it int her mouth, sucking contentedly.

"There's one more thing I want to see you do. Is that okay?"

"Anything."

"Get up and go over to the potty."

The girl did so quickly and shuffled across to the toilet, one hand still dipping into her butt groove and savoring the sensation there. Kristin rose and followed, fingers still gently massaging her puss. Mina wondered what was going to happen next. But she didn't have mush time to think about it, because Kristin had one hand behind her knee and was lifting her leg.

"What are you doing?"

"Climb up, climb up. You saw how I did it. Do it the same way."

"Kristin..."

"You'll love it, I swear. Please. You got to watch me when we were spying, it's only fair."

Reluctantly, Mina let her dark haired stepsister arrange her in a squatting position over the bowl, with her feet on either edge of the seat, just like she'd seen Kristin do. What she wasn't prepared for was Kristin squatting down right next to her upturned knees, resting her cheek on Mina's ankle. She'd never felt so exposed, the stepsister could see all of her peepee and her butt hole, and it was a bit disconcerting and a bit thrilling, too.

The 15-year old reached down between her own legs and started masturbating her pussy, squeezing and stroking. Despite her embarrassment and uncertainty, Mina found herself getting turned on by this flagrant sexuality. Quivers ran through inner thighs.

Kristin licked her lips. "Go ahead, it's okay."

Mina felt her pussy tingle and her anus flex, but she couldn't bring herself to do it, not like this. Despite everything they'd done together, having Kristin watch her so closely, so expectantly, got her too anxious. She couldn't understand why this made her shy, but it did.

"Ungh. I can't do it. I want to but I can't." She looked to her big stepsister, panting, already halfway to ecstasy with her fingers busily stroking her wet, sweet pussy. "Can you help.?"

Kristin stared at all the naughty loveliness exposed to her, her own masturbating fingers spurring on her desire. She could swear she smelled her little stepsister getting wet again. "Oh yeah, Mina, I'll do it all if you want."

The girl nodded slightly.

And with that, Kristin lunged forward and began furiously licking Mina's smooth, vulnerable, delectable slit. She frigged herself harder as slathered her tongue directly over the 11-year old's tiny clit, which she found hard as a bean and fully aroused. Her free hand blindly reached between the Mina's spread thighs and ran along her slippery ass crack until her fingers found the girl's twitching pucker. Kristin took her middle finger, slid it in past Mina's slick tight anus and deep into her rectum.

The pleasure was electrifying and happened all at once, too much, overwhelming Mina's senses and going past pleasure into scary. She nearly panicked. She gripped the toilet tank with both hands, trying to lift herself. But her body refused to listen, her hips and thighs siding with the lusciousness emanating from her pussy, the exotic excitement so deep inside her butt. She found herself thrusting her pelvis against her stepsister's wonderful licking mouth. Her back arched, pushing down into the finger invading her tight, dirty hole. She helplessly gave in, her body inviting the very feelings she tried to resist, until at last she was going, "Nuh- uh! Ah, anh, nuh-uh, uhf, uhm, mmmm, oooohhhh..."

As she suckled Mina's immature but sensitive love button, Kristin felt her stepsister's anus quiver and her belly contract, and knew what was happening. She began lapping faster, tasting the fresh pussy juice that was oozing from Mina's vagina. Down between her own spread legs the 15-year old twisted her hand, slipping her thumb into her vagina and her two fingers up her ass. She vigorously fucked herself, matching what was happening to her astonished stepsister.

This was so dirty, so kinky, and Mina was doing it for her right now. Kristin tasted the little girl's tangy pussy, felt her knuckles bump her chin as they probed deep in her ass, and she imagined herself as an 11-year old again, and being introduced to sexuality the way she was showing Mina, imagining being on the seat and feeling this for the first time. And with that thought she began to cum, pussy and ass clutching her wet fingers, moaning ecstatically into Mina's pussy.

When Kristin started moaning against her peepee, tongue still licking urgently on her thrilled clit, she knew her big stepsister was cumming because of her, and the sound seemed to go right through her pussy and into her ass. Mina's anus began contracting, squeezing Kristin's finger and she found herself cumming again, massively and without any warning, a hard bucking cum that happened deep in her butt and shot out from her clit.

Kristin broke contact and leaned back, startled by the fury of the orgasm shaking Mina's little body, her thighs quaking, her hips thrusting out then bearing down, urgently, uncontrollably, her anus convulsing on Kristin's finger, her face locked in a silent scream.

Finally, heaving in a huge, scooping breath, the little girl unwound, and she almost slid awkwardly off the toilet but Kristin steadied her with one hand, while the other still had a digit firmly in the girl's ass. Mina felt faint, but the cumming eventually subsided and left her filled with this glowing, unbelievable feeling.

"Mina, you okay?"

"Soooo good."

Kristin let go, and Mina held on to her knees. The 15-year old slid her finger out of her stepsister's asshole and Mina shivered with a little groan. Grinning, Kristin got back up on her knees and dipped one finger deep back into her own ass, rubbing it around and almost getting aroused again before she removed it.

She held up one finger. This is your ass. I know how it tastes, and I want to lick it again and again."

She held up the other. "This is my ass. Do you want to know what it's like?"

Mina nodded, opening her mouth and extending her tongue to receive it. Kristin slipped them into both of their mouths at once, and they looked into each other's eyes as they sucked, savoring one another's dirtiest, most intimate flavor.

Mina waited til Kristin withdrew her finger before she sighed. "Oh my god, I could never guess just watching you that it could feel like this."

"Well, now you know. I hope you liked it half as much as I liked doing it to you."

"I loved it all. I love masturbating, and doing all the naughty sex things with you. And cumming. Cumming is soooo good."

"And you don't need to spy anymore. If you want to watch me, or do stuff with me, just tell me."

"Oh! I'm gonna want to do this all the time!"

"We'll see. I'm betting you're going to be pretty sore tomorrow." She tussled Mina's hair. "Speaking of that, we better get back to bed."

They spent a few quiet minutes cleaning up the bathroom, disposing of the evidence. Their pajamas got rinsed in the sink then thrown in the hamper. They darted quietly back across the hall, stifling giggles. Mina leaped into bed, delighted to sleep naked next to her new lover, her stepsister. But Kristin tucked her in, determined to get some water into them before they went back to sleep.

She crept nude into the kitchen and poured out two chilled glasses from the Britta pitcher. She imagined all the fun they could have together this summer. Unless Janelle was at home editing, they were alone in the house all day. She pictured them sweaty and straining by the pool, groping each other in the water. She saw Mina propped on the big marble kitchen island while she feasted on the girl's delectably smooth puss. She pictured herself facedown with her knees spread on the couch and Mina between them, dipping her dainty fingers into her big stepsister's quim and asshole. She imagined them both pressed to the big glass wall, naked, masturbating, and the whole Valley being able to see. As she daydreamed and returned the pitcher to the fridge, she heard someone say her name softly.

Kristin pulled her head out of the fridge to see Janelle, standing in the doorway. Her long frosted blonde hair was a tumble, her cheeks looked especially rosy, and she was wearing a long white silk robe. Kristin was very aware of her own nakedness in the stark light of the fridge.

"Hey," she replied nervously.

"Be careful about leaving your bedside light on," Janelle said quietly. "This late, someone might get curious."

Kristin struggled with a response as Janelle shifted, and the 15-year old stepdaughter suddenly realized that Janelle's robe didn't have a sash to tie it shut. As her gorgeous stepmother turned, it parted a few inches in the middle, revealing in the dim light the golden flesh inside the white robe - the inner curves of both of her small, high-riding breasts, her taut, well-toned abdomen, the smooth shaved v of her sex, the contour of one long inner thigh.

Janelle effortlessly held her stepdaughter's gaze. "You girls were kind of noisy tonight. Max is a heavy sleeper, but still. You don't want to spoil our fun."

With that she stepped out of the doorway and receded back into the darkened house.

As Kristin carried the water back to the bedroom, she tried to process what just happened. What she kept coming back to was that Janelle said, "our fun."

And when she reached the bedroom door, she glanced across the hall at the bathroom door. Wrapped around the knob was a white silk sash. And below that, barely visible, Mina's tool still jutted from the lock.
