I woke up from a peck on the lips. “Took to this quick, didn’t you?”, I mumbled, eyes still closed. Bo giggled.

I opened my eyes to see her smiling at me. We were lying side by side. Bo moved closer so she could give me another peck. I pursed my lips, waiting for her. When our lips met again, I smacked mine, too. We both giggled. “This is nice”, she said.

We exchanged a few mutual pecks. Unlike what I’d seen in movies, Bo didn’t kiss me at an angle to avoid our noses crashing into each other but just pressed her nose to mine. I absolutely loved how innocent that felt. After a while, I opened my eyes. “Don’t move”, I told her.

Bo smiled in anticipation. I put my lips on hers, but instead of smacking them, I let them linger there, nibbling ever so slightly on her upper lip. I didn’t dare go any further and pulled away soon. “That felt really weird”, she said. After a few seconds, she added, “it felt really cool.”

We just looked at each other for a while. I thought she might kiss me again, but instead her eyes fell back closed. After a few minutes, I saw them move underneath her lids and thought she must be dreaming. I kissed her softly on the lips. Her eyes stopped moving and she sighed with her lips closed. I wasn’t sure if she was still asleep.

“I had a dream just now”, she said after a bit.

“What about?”, I asked.

“There was a fairy that took me to a magical place. I think I was a fairy too. We were flying through giant blades of grass. It was at dusk. There was a pond with frogs that were bigger than us. Fairies rode on some of them. I wanted to ride one too, so I got on top of it. It jumped towards the pond and I got scared. When we went underwater, at first I thought I was gonna drown, but then I noticed that I could breathe underwater and I thought, ‘how cool is it that I can breathe underwater?’ I did a looping, and while I was going around myself, I noticed that I was a mermaid. I wasn’t surprised, because I didn’t remember that I’d been a fairy before. I wanted to breach out of the pond like a whale, but I woke up the moment that I got to the surface.”

“You dreamed all that in one minute?”, I asked, laughing.

“That was only a minute?” Bo opened her eyes, looking at me surprised.

“Yeah”, I said. “I’ve heard that when you dream, time goes by ten times as fast. I didn’t know if it was true.”

“I guess it must be”, she said.

I wondered if she’d realized that she’d woken up from my kissing her. I went through her hair with my hand, which made her smile. She petted my head, too. I asked her, “Wanna get up and go downstairs?” She said “okay.”

Instantly I hated myself for asking. I realized I was still scared of her deciding that all of this was wrong, or maybe bringing it up casually with our parents because she thought it wasn’t wrong.

I managed to pull myself away from Bo and get out of bed. I looked back at her still lying down. She gave me a bright, cheeky smile, lifting her arms up. I rolled my eyes at her, pretending to be annoyed, but couldn’t help grinning. I took her by the wrists and pulled her into a sitting position. She got out of bed and stretched, raising her arms again. In a surprise move, she got on her tip-toes and wrapped her arms around my neck. She gave me a soft kiss on the cheek that made the cutest sound. “See you downstairs”, she said quietly into my ear. Then she let go and off she flew. Dazzled, I slowly plodded behind, rubbing my eyes to make sure I wasn’t still dreaming.

Downstairs, I looked into the living room. Mom was sitting on the couch with a book. “Morning, mom”, I said. “Good morning”, she said and waved.

I went to the kitchen. Bo was filling two cups with milk. I looked at the clock and saw it was half past eight. Bo put the cups in the microwave.

“I’m making instant cacao for us”, she said.

“Thanks”, I said.

“You can go sit on the couch”, she said.

“Okay”, I said and went back to the living room, sitting at the end of the couch opposite my mom.

“You girls are up early”, mom said, smiling.

“Yeah”, I said, not mentioning that Bo and I had had a sleepover. I picked up a Carl Barks comic from the table and pretended to read it.

“Good morning, mom”, I heard Bo say a few minutes later. Mom greeted her back. When Bo came over, I put down the comic and she handed me my cup.

“Thanks”, I said.

“You’re welcome”, she said and sat between us. I drank a few sips, put the cup on the table and went back to my comic.

“Mom, can I take a bath?”, Bo asked after a bit. Mom thought about it.

“Okay”, she said eventually. “You should go and turn on the water.”

“Yippee”, Bo exclaimed.

She got up and walked to the bathroom. I heard her turn on the water. When she came back to sit between us, she asked, “Lisa, do you wanna take a bath with me?” My heart sank to my stomach. “I donno”, I mumbled. The last time we’d taken a bath together, I had been around eight and Bo five, a good while before I’d realized I liked girls, much less that I had a thing for my sister.

“Please?”, Bo said. I was still looking at the comic but I couldn’t make out the pictures. My mind was racing.

“Lisa probably feels too old for that”, mom said when I didn’t reply.

“Huh?”, I said, looking up. “Sorry, I got distracted with the comic.” I put it down. Instinctually, I pretended that I hadn’t realized what they’d been talking about so I could feel out the situation some more.

“Bo said she wants you to take a bath with her”, mom said.

“Oh cool, yeah, sure”, I said, looking back down at the comic. I thought I sounded pretty calm, but couldn’t be sure.

“Really?”, mom said. She seemed surprised. I glanced at her to see her smiling.

“Yeah, I haven’t taken a bath in a while”, I improvised.

“Yay!”, Bo said, drinking some more of her cacao. Mom picked up her book again.

Bo was first to finish her cacao. She took her cup to the kitchen and stayed gone for a bit. Then I heard her yell, “Bath’s almost ready!” Without looking up, I yelled back, “Gonna be there in five”. I didn’t want to seem too eager. “Okay”, Bo replied.

She didn’t come back. I turned pages in the comic for a few more minutes, then put it back on the table and got up.

“Have fun”, mom said.

“Thanks”, I said and went to the bathroom. The door was closed already, but I heard water still pouring into the tub. I knocked on the door.

“Come in”, Bo said.

I went in and first noticed her pyjamas on the floor. Then I saw that she was sitting in the bathtub already, surrounded by mountains of foam. Her knees and shoulders were still looking out of the water. I closed the door behind me. Bo giggled and squeezed more shampoo under the faucet, fueling the foam production.

“Come on in”, she exclaimed.

“Close your eyes”, I said, out of instinct. When I saw that she did, I got out of my pyjamas.

As I pulled down my panties, I noticed they were a little wet. I felt myself blushing. I’d never been so wet that it had showed on my panties before. I covered them up with my pyjama top, looked at Bo and saw that she still had her eyes closed. I climbed into the bathtub and slowly eased myself into the hot water. I sat down facing Bo, surrounding her with my legs, careful not to touch her. Moving some of the foam over to my side, I covered the area between my chest and knees.

“You can open your eyes now”, I said. Bo giggled when she saw that I was hiding underneath the foam. I felt nervous but grinned.

“We haven’t taken a bath together in a long time”, she said.

“Yeah”, I said.

Neither of us spoke for a while. We just relaxed in the hot water. The sound of the stream pouring into the tub was a meditative drone. I got into a dreamlike state, gazing at Bo, who had her eyes closed.

Her face was flushed from the heat. Steam was rising up between us. Her hair, which was usually straight, fell down in waves around her face and on her forehead, curled up from the humidity. She looked incredibly cute. The sight of her bare knees still jutting out of the water was driving me insane. I could hear my heart bumping in my chest, and I felt like the vibrations were traveling through the water.

After a few minutes, Bo opened her eyes and gave the tub a critical look-over. Following her survey, she grinned at me, grabbed the bottle from the side of the tub and happily squeezed even more shampoo into the stream, cackling like a maniac.

“This bath needs more foam. Foam is good. Foam is life”, she exclaimed. Bo’s mood was infectious. I caught myself giggling.

“You’re a dork”, I said. She looked at me.

“Yeah, but I’m a foamy dork”, she explained patiently.

I laughed and poked her flank with my toe. She squealed in surprise and clasped her legs together, creating ripples in the water. When she relaxed again, some of the foam between her knees was gone. Seeing her bare lower legs made me shiver despite the heat.

The tub was getting pretty full, so Bo turned off the water. She scooped up some foam and put it on top of her head, crowning herself.

“I hereby declare you princess Foamy”, I said. Bo giggled, then put on an earnest look.

“I shall reign supreme over the lands of foam! I vow to keep all citizens of Foamland foamy at all times”, she promised. I jutted out my lips and applied some foam to my top lip.

“Arrr! I’m the evil pirate Clearwater, and I’m not going to subject to your despotic rule!”, I threatened in a rumbling voice.

I pushed some of the foam from my side over in her direction, uncovering my chest. She giggled and waved the foam back to me. I proclaimed, “Princess Foamy! Your wasteful ways have terrorized Foamland for too long! I shall take this foam and put it back to its original purpose.”

I scooped up most of the foam that was covering me, piled it on top of my head and began massaging it into my hair as big chunks fell down around my shoulders. Bo looked amused, but she had quieted down. I thought the foam on her side probably blocked her view of my lower body, but I felt incredibly excited to be flashing my boobs to her. I couldn’t tell if she was looking at them, partially because foam was running down my face. I made a helicopter noise with my lips and shook my head wildly, sending foam flying across the tub at Bo. She giggled quietly. “I surrender”, she offered meekly, slowly sliding deeper into the water with a theatrical sigh.

Bo’s head went under, only her crown still floating on the surface. I felt her feet come to rest on my stomach. I gulped. My gaze followed her legs from her feet out of the water to her knees and back underwater to the junction of her thighs. The water was wavy from the motion, and her legs were too close together for me to really make out anything, but I thought I could see that she was still hairless. I only got to look for two seconds before she softly pushed herself back up, rising from the water again. The crown was lifted back on her head, diminished in size now. Bo’s lower half disappeared under the the foam again, but her chest was uncovered. While she wiped her eyes, I caught myself staring. Her little nipples sat on mounds that were barely bigger than her beautiful dark areolas. The inside of my mouth was dry and I thought I was gonna give out any minute now. I scooped some water over my head and washed the foam out of my hair.

“The heat is getting too much for me”, I told her truthfully. “I’m gonna get out.”

“Okay”, she said, closing her eyes without me saying anything.

I slowly stood up and reached for a towel. I could see better from this position, but Bo’s hands had come to rest in her lap and again I couldn’t make out much, which was probably for the better. I stepped out of the bathtub, dried myself off and wrapped myself in the towel.

“You can look”, I said. Bo opened her eyes.

“I’m gonna stay and enjoy the water a little more”, she said, looking at me.

“Okay, Mrs. Foamy”, I said. Bo smiled brightly. I gathered up my clothes and left the bathroom.

“Out already?”, I heard my mom call from the living room. I went over to the door.

“Yeah, I was getting bored. I’m squeaky clean already anyway. Bo’s gonna stay in a little longer, though”, I said.

“Okay”, mom said, going back to her book.

I went upstairs outwardly calm, aware of how badly I needed to touch myself. I passed my parents’ bedroom and heard my dad still snoring. In my room, I put my clothes on the bed and dropped the towel. Feeling incredibly naughty, I continued naked into Bo’s room.

I went through the clothes on the chair she used as a hamper and found a pair of panties. I sniffed it. It smelled faintly of pee. That was enough to drive me insane.

I crawled into Bo’s bed and underneath her blanket. I pulled it up so that only my upper body was covered but my lower half exposed, which made me feel extra naughty. I pulled Bo’s panties over my head, the crotch over my nose, breathing her smell.

My trembling right hand found my pussy. It was so slick that it couldn’t be all that wet just from the bath. My whole body was quivering, both from my naked legs being exposed to the cool air and from the adrenaline pumping through me. I slowly moved my index finger back and forth over my clit, torturing myself on purpose. I wanted to stretch this out.

When I felt myself getting close, I stopped touching my clit. Teasing myself instead, I started tracing lines on the sensitive flesh just around my pussy and lightly trailed a finger through my wet lips.

When I couldn’t take it anymore, I went back to slowly massaging my clit. Not able to hold back from moaning, I pushed the crotch of Bo’s panties into my mouth. I held it in place and started to suck on it. I had never felt this depraved before, or this horny. I kept going at my clit but never picked up speed. I was shivering violently and breathing hard. I could hear myself whimper pathetically, which turned me on even more.

The orgasm hit me unprepared. A flash of lightning zapped through my body. My hips bucked violently, and now that I was at the peak, I went wild on my clit until it became too painful. My ears fell deaf and all I could see was stars. I came for at least twenty seconds.

Still breathing heavily, I could feel myself drift into a coma, but the remainder of my consciousness told me that I was a dead man if anyone found me lying in Bo’s bed, my hand between my naked legs, with Bo’s panties pressed to my face.

I tried to stand up, but I was still shaking so badly that I couldn’t trust my legs. I put Bo’s panties back on her chair and crawled back into my room on my hands and knees.

I somehow managed to put on my pyjama top and panties. Slipping into my bed, the last thing I noticed was that my face was drenched with tears. I must have cried through my orgasm. A warm, fuzzy darkness soon enveloped me and I passed out.
