Fun in bed with sleeping younger sister

I always slept nude when younger through my teens. I still do. It was just more comfortable, especially on hot nights. I was usually on top of the covers too. My mom walked in on me a few times when dropping off clean clothes in the mornings when I started doing it (age 9 or so) and it surprised her, but she got used to it. She said it was my room and I could do what I wanted. From that point on she just knocked and walked right in. Guess she figured my nudity was fine but didn’t want to interrupt me doing anything else — though she did a couple of times. 😉

One night when I was a young teen (mid-70s), I woke to feel a hand on my penis and it freaked me out a little. I looked over and saw my younger sister snuggled up against me asleep. She suffered from nightmares and normally crawled into bed with my parents, but I figured she must have wandered into my room by mistake. In the process of her snuggling up to me her hand ended up on my dick.

I thought about moving it, but just left it there. Figured why not. I lay there enjoying the feeling and even started popping a boner. At that point her hand slipped off. So I took her hand and gently and slowly began jacking myself off with it. With my other hand I carefully slipped my hand into the back of her pajamas and started caressing her ass cheeks. I’d peeked in on her in the bathroom a couple times and loved her tight little ass, especially when she bent over to dry her feet after a shower.

Luckily my sister was a sound sleeper so she didn’t wake up. I took my hand off her ass cheeks and slid it around to her front. As I continued to stroke my boner with her hand, I played with her nipples. I almost came but held it back because I wanted to enjoy that moment as long as I could. I panicked when she suddenly sighed and started to move. I thought she was waking up.

To my relief, she just adjusted her position and her head ended up resting on my stomach right next to my erection. She was still deep asleep. Not wanting to waste the opportunity, I gently put my hand on the back of her head against her soft blonde hair and adjusted my dick until it was right next to her mouth. Then I softly pinched her nostrils closed until she opened her mouth to breath. It was a technique I read about in a porn magazine (remember those?) back then.

I released her nostrils and slipped the head of my penis between her lips. I waited to see if she woke. When she didn’t, I pushed it in a little more. The feel of her young lips and tip of her tongue against my dick felt incredible. I almost shot my cum into her mouth but held it back. I then started to slide my dick in and out of her mouth. It was incredible. I’d had my dick sucked by both guys and girls before. But doing it with my sleeping sister just filled with me with excitement for some reason.

As I continued to fuck her mouth, I played with her ass cheeks again and even lightly fingered her butthole. Every time I started to cum, I stopped until I regained control, and then started mouth fucking her again. I kept sliding my dick in and out faster and faster and yet she never woke up. Finally, when I couldn’t hold it any longer, I slid my dick out of her mouth, took her hand, and stroked myself with it. When I was about to cum, I grabbed my shirt from a chair by my bed and shot into it.

After I caught my breath, I grabbed a clean edge of the shirt and wiped cum off my sister’s hand. I noticed a little bit on her hair so I wiped it off with my fingers. She stirred a moment, but stayed asleep. I then leaned over and kissed her on her sweet lips. I could actually taste my pre-cum. Finally, I decided it was time to wake her up. I jostled her awake and she looked at me groggy. I told her she climbed into my bed instead of mom and dad’s. Tired, she asked if she could stay awhile. I said sure.

Then she noticed I was naked and asked why I wasn’t wearing pajamas. I said I always sleep this way because it’s more comfortable. She paused then asked if she could sleep naked too. My heart skipped and I said of course. So, still groggy, she stood up and slipped off her pajama top revealing her small round nipples and budding breasts. Even though I had just cum, my erection got even harder. Next, she slipped off her pajama bottoms and panties giving me an eye full of her wonderful ass. I wanted to grab it and stick my tongue – and other things – into it.

As she turned to climb back into bed, I noticed the light wisps of blonde pubic hair between her legs. Then she lay next to me and snuggled against my side, putting her arm around my waist and her left leg over my leg. Within moments she was sound asleep again. I couldn’t believe it. I was lying there in bed with my younger sister — and we were both stark naked! The feel of her bare skin against mine was fantastic. After I was sure she was deep asleep again, I decided to play some more.

I stroked my dick with her hand again as I felt up her ass cheeks, nipples and pubic hair. I even gently slid my finger across her pussy lips. They soon grew moist and I was dying to lay her back, spread her legs and pump my dick inside her hard, but I knew that would be a huge mistake. Instead, I gently lay her back, spread her legs and started licking her pussy. I cupped her ass cheeks in my hands as I tongued her pussy and pubes. So delicious. I did that until the cum inside me built up so much I couldn’t hold it anymore.

So I moved her onto her stomach, and after generously lubricating between her ass cheeks with my tongue, I began to slide my erection between them. I didn’t penetrate her ass hole, though I really wanted to. I just slid my dick between her tight cheeks until I exploded cum all over her back. An older cousin taught me how to do that two years earlier when he banged his dick between my cheeks. I was shocked that my sister didn’t wake up. At that point I figured I could have fucked every hole on her body and she’d still sleep through it. Lol. But being the caring brother, I didn’t.

Once drained, I slid the cum covered head of my penis along her tongue. She instinctively licked her lips and swallowed. At that point I grabbed another shirt, cleaned off her back, kissed both her ass cheeks so hard I’m surprised I didn’t leave hickeys, then covered her and fell asleep next to her. The next morning I woke and she was gone. I guess she never told mom or dad we slept naked together because they never said a word. She didn’t say anything about it either until a year later when she admitted she had been awake the entire time.
