Sleeping Tight Taboo sex stories

I had just woken up, and I turned my head over to look at the alarm clock. It was almost 2 o’clock in the morning. I turned over and looked at my baby sister, Jenny, who was sleeping on her back. She looked so delicate and relaxed as she slept beside me.

Our father was rebuilding her bedroom; therefore, it was decided that she could sleep with me until her bedroom was finished. Jenny was 16 years old, just two years younger than I was. She had short blond hair, and was about 150 cm tall.

I ran my hand gently over her cheek. It felt so warm and soft, and I let my fingertips wander over her soft lips. Suddenly a crazy thought come into my mind.

Why did I not touch her? I thought.

I felt how my penis was getting harder, and how my heart began to beat harder in my chest. I wondered if I should dare, and what could happen if she woke up. I imagined that she would be mad, finding her big brother touching her as she was asleep.

I thought about that for a while and came up with a great idea. If she should wake up, I could just pretend to be asleep and she would not think that I did it on purpose.

I felt calm knowing what to do if she woke up and I moved my body against hers. I let my hand slip under the sheets and slowly placed it on her belly. I could feel her soft belly through her pajama top. Slowly I moved my hand up and placed it over her breast. It felt so soft and I squeezed it until I could feel her nipple grow in my palm. I unbuttoned her top; my fingers met her soft warm skin as I slid my hand inside.

Jenny moved a little and I froze. I did not dare to move an inch as I watched her face in the moonlight. I observed her for almost 5 minutes, so that I would know that she certainly was asleep.

I began to move my hand inside of her pajama top and soon my fingertips felt her soft breast. I casually cupped my hand over her right breast. The skin of her breast was smooth as silk and I started to caress her aureoles. Soon I noticed that her nipple became harder and I started to pinch it a little between my fingers.

I could feel how my cock was about to blow my underwear to pieces. I slid my upper leg over her thighs and flipped my cock up, along my stomach. Slowly I started to slide my cock up against her hip, forcing the foreskin to caress the top of it. I could feel how her breast became warm and I let my hand move down to her soft belly.

My fingertips reached the elastic of her pajama pants, and I stopped. The tension that was beginning to build in me almost made me cum. I stopped rubbing my cock against her hip. ‘God, could I do this?’ I thought.

I wanted to feel her and I felt that I could not stop. Not now, anyway. I pressed my fingers under the elastic of her pajama pants, and forced them under the fabric. My fingers ran over her almost bald vulva and I cupped my fingers over her slit.

My cock was pounding like a hammer, and slowly I started to rub it against her hip again. I started to fondle her outer lips, and stuck one fingertip between them. Soon I felt it become moist and sticky.

“David, what are you doing to me?”

I froze like a stone statue, right there in bed. The thing that could not happen had happened; my baby sister caught me. I did not know what to say; there I was with my hand against her pussy and humping my cock against her hip.

‘What should I do now, what shall I say?’ I thought to myself.

“David, what is that thing pressing against my hip?” Jenny asked me, with a little fear in her voice.

I swallowed and stopped rubbing my cock against her.

“I…I’m making it nice for you. Do you like it?” I asked her.

“It feels strange, David. But…It feels kind of nice on my pussy.”

“It does?”

“Yes…It kind of tickles and…Move your fingers over it again, David!”

I began to caress her moist slit with my fingers, and immediately Jenny began to thrust her hips against my fingers.

“Yes…It feels nice, David”

“Do you want me to continue doing it?” I asked her and held my breath.

“Mmm, yes please, keep doing that!” she replied.

Slowly she forced her hips up and down and soon two of my fingers slid into her sticky crack. I felt the inner lips of her labia, and she gave a soft moan.

“Oh, David, it feels like I am going to pee,” she said, terrified.

“It’s okay, sis. It’s normal to feel that way.”

“Are you sure?”

“Yes, believe me,” I said to her.

I found Jenny’s hard clit and started to move my fingertip around it. First slow and gentle, then faster and harder. She started to moan louder and pushed her hips harder against my fingers. Her breathing became deeper and faster.

“Oh, David I feel so tense. Oh David, please don’t stop. Oh, …oh, …oh.”

Jenny forced her hips way up, and stayed in that position as her body became stiff. I could feel her pussy become even wetter and I knew that I had made her come. After a while, she lowered her hips down onto the mattress and her breathing became calm again.

“David, what was it?” she asked.

“It was something real nice called an orgasm, sis,” I replied.

“I liked it,” she said and started to giggle.

I wanted to cum now, so badly. I wanted to stick my cock inside her and fuck her like crazy.

“Sis, do you want to feel it again?” I asked.

“Yes, you can do it again. Touch my pussy again, David.”

“OK, sis. This time I won’t caress you with my fingers,” I replied.

“You won’t?”

“Now, I am going to use my…cock,” I said slowly and waited for her reaction.

She was quiet for awhile, like she was thinking very hard. Then I felt her small hand move down and grab my hard cock. I almost came as her small fingers wrapped round my hard shaft and squeezed it.

“Do you mean this?” she asked me.

“Yes sis. That is my cock.”

“But…It seems so big,” she said, gasping.

I realised that she had not felt a cock before, because my cock was not really so big; just normal I guess. I had measured it once and the ruler said that it was 7 inches.

“It’s okay, because your pussy is so wet and that will make my cock slide into you quite easily,” I replied, reassuring her.

“Are you sure?” she asked me.

“Yes, and you will find it even nicer than before,” I assured her.

“Okay then, let’s do it,” she said and slid her pajama pants off.

I took of my underwear off and threw it on the floor, and then I placed myself between her thighs. I grabbed my cock and guided the top of it inside her soft slit. She started to moan right away when I forced my cock inside her.

She gasped aloud as my cock went inside her and I felt how warm and moist her vagina was. It felt so nice to have her tight vagina surrounding my cock. I started to slide my cock in and out of her vagina. I could hear the slaps as my crotch was banging against her wet labia.

“Oh, that is even better than before!” Jenny gasped.

“Mmm, I told you so, sis.”

I increased the speed and my cock thrust in and out of her vagina like a piston in an engine. I felt her vagina become hotter and tighter. Her breathing became deeper and she moaned softly. “Oh, ..oh, ..oh. It’s happening again, David!” she moaned.

I could not speak; all I wanted was to cum right now. I felt how her vagina began to pulse as the friction against my cock increased. I felt the tickling and burning sensation inside my crotch and I knew I was about to cum.

I slipped my cock out of her vagina and started to jerk it hard. I moaned out loud as I felt myself begin to squirt. I jerked my cock until all the sperm had left my balls. Then I moved away from Jenny and lay beside of her.

“Oh, that felt really good, David,” Jenny told me breathlessly.

“Yes, I told you so, didn’t I?” I replied.

“But what was it that came out of your cock?” she asked me.

“Its called sperm, sis. That comes out of us guys when we have an orgasm.”

“It felt quite warm as it went on my pussy. I liked it…” she said, smiling.

“Me too,” I replied.

“Can we do it again!” she asked me impatiently.

“No, not tonight, sis.”

“Why not?” she demanded.

“Because, my cock can only do it once, then it has to rest,” I explained to her.

“That’s too bad,” she said, “but tomorrow night, then?” she asked.

“If you want to. Yes.”

“I really want to do it again. It feels no nice having you inside me,” she said.

“It feels nice for me too,” I said and kissed her.

She responded to my kiss, put her tongue inside my mouth and let it play around my tongue. I was happy and thankful that my dad had come up with the idea of rebuilding Jenny’s bedroom, and I hoped that it would take him a lot of time to finish it.
