This happened last week and I am finally writing about it. I still can't believe this happened to me, I am so excited just thinking about it that my hands are shaking writing this. I am 18 years old and my sister is 15. Last week my sister had her friend Kerri over for a sleepover. I usually find my sister's friends annoying, but Kerri is different. She is tall, with long legs and bouncy brunette hair. She has a nice tan and bouncy C-cup tits. I know about bra sizes from hearing my Mom and my sister talk. My sister and Kerri were goofing around in my sister's room most of the night while I was watching TV in the living room. Our parents were gone for the weekend, so I was the man of the house. It was close to midnight, and I was watching a pretty hot movie with lots of T & A action. I guess my sister fell asleep so Kerri came out of their room to see what I was doing.
'What are you up to?' she asked me. She was wearing a long tee shirt, and I could tell that she wasn't wearing any bra. Her tits kind of swayed when she walked and it was better than the movie. I felt my dick get a little harder when I saw her nipples under her tee shirt. I told her I was just watching a movie that my parents probably wouldn't approve of. 'Mind if I join you?' she asked. I told her sure, why not?
I was sitting on the couch and she grabbed a pillow off the chair and laid down on the floor in front of me between the couch and the TV. She was laying on her stomach with her head propped up in her hands. When she came in, the scene on the TV was getting pretty hot, this super beautiful blonde had her shirt off and she was kissing some dude with long hair. He was kind of thumping her nipples with his thumb. Kerri didn't say a word, she just started watching the movie intently. Her legs were bent at the knees and she was kind of swaying her feet back and forth while she watched.
I was getting horny from the action on the screen and from looking at her ass. As she swayed her feet back and forth, the tee shirt she was wearing had worked its way into the crack of her ass, and it was turning me on. My dick was standing straight up in my shorts, and when she turned around to ask me if I wanted anything to drink, I think she might noticed it before I crossed my arms over it.
When she laid back down on the floor after getting us each a soda from the kitchen, I noticed that her tee shirt had fallen higher up this time, and it was barely covering her ass. The bottom of the tee shirt was right where her ass cheeks started from her legs. I don't know if she did that on purpose or by accident, but I thought I could see a few wisps of hair between her legs now and I was so hoping and hoping that she wasn't wearing any panties. Kerri was getting me super turned on as she kept swaying her feet in the air and my cock was now pounding inside my shorts. As she gently rocked her feet back and forth, her legs gradually spread wider and further apart. My hands literally started shaking from excitement as I realized that she wasn't wearing any panties. My cock was pulsing against the fabric of my shorts and I could make out the outline of her pussy lips. They were the long kind, that flared out on each side, and I could see that she didn't shave, which turned me on even more. She had super dark pussy hair that was thick and curly. I started rubbing the length of my cock with my thumb as quietly as possible, and I don't think that she could hear me.
As she kept swaying her legs from side to side, her tee shirt kept riding up higher and higher. Her skin was super white under where her bikini went, and now I could clearly see her asshole above her pussy. Her ass cheeks gently opened at her puckered little asshole. She had a perfect bubble butt, her cheeks were so soft looking and she had tiny little hairs on her ass. Not a word was spoken as the movie continued on, but my eyes were totally transfixed on Kerri. At this point I still didn't know if she was intentionally letting me see her or if it was an accident, but I didn't care, I was loving it. By now the precum oozing out of my cock head had formed a wet spot at the top of my shorts. I looked at Kerri and I could see that her pussy lips were wet looking, and there was a clear drop of fluid forming at the top of her inverted pussy right were her clit was. The drop was getting bigger by the minute as she continued to sway her legs, and by now her legs were spread even wider and her tee shirt had crept up to where the entire lower half of her ass was showing.
I could now clearly see her clit protruding from the top of her pussy lips, it was sticking out like a half an inch, I had never seen one that big looking at porn online. I guess the movie was turning her on too, because as she rocked her feet the clear liquid at the top of her pussy began to form a long, stringy drip from the top of her pussy down to the carpet. My throbbing cock was aching for attention so I quietly pulled it out from my shorts and lowered the waistband down under my balls. My dick is eight inches hard (no lie), and that night it was so swollen I swear it looked like it had grown another inch. I was gently pulling up and down on my foreskin, so hoping that Kerri's little show would continue. My precum was making a tiny popping sound each time I rolled my foreskin off of my cock head, but the TV was loud enough to hide it from her. When I looked up from my dick, I noticed that she was just holding her head up with one hand now, her other hand had disappeared down under her front. My heart felt like it had leapt into my throat when saw the pink fingernail polish of her tiny index finger rubbing above her clit in little circles.
Now the fluid was literally oozing out of the top of her pussy as she rocked her feet back and forth and rubbed little circles around her clit. Her clit kind of bounced from one side to the other as she rubbed above it, kind of like my cock does when I hold it near the base. There was a wet spot about the size of a coffee cup on the carpet below her pussy and there was still a gooey string connecting her pussy to the puddle of pussy juice. I was pulling harder on my cock, and I could tell I was going to cum soon. I didn't know what I was going to do with the cum, but I was so horny I didn't care. Right then her rubbing became more frantic and I saw her cute little asshole start to pucker and pulse over and over again. She let out a barely-audible little 'Mmmm' sound and suddenly a long thick stream of clear liquid shot straight back out of the top of her pussy and landed on the carpet about three feet away. That did it for me, I let out a tiny grunt as my cock erupted in string after string of cum. The first blast went over my shoulder and hit the wall behind the couch, and then the rest landed on my shoulder and chest. While I was having the most intense cum of my life, her little asshole continued pulsing as her orgasm continued and she ground her hips down hard onto her hand. By now her legs were totally splayed apart, and I could see everything - her cunt, her pulsing asshole, her finger, her long clit. Suddenly two more thick streams of pussy cum shot out as she continued grinding her clit on her hand and her asshole and pussy continued clenching over and over again. It was the fucking hottest thing I had ever seen, and I couldn't believe my own eyes.
We were both panting now, winding down from our cums, when I looked around and thought it looked like we'd just played war with super soaker guns. There was pussy cum and my sperm everywhere! I quickly decided to pretend like I was sleeping, because I didn't want to embarrass her. I threw a blanket over my shorts and shirt just in time to cover my cum as she got up and tip-toed into the kitchen. She disappeared into my sister's bedroom, and I got up to inspect the damage. Besides the huge puddle under her pussy that had soaked into the carpet by now, there were three long strings of pussy cum, the longest of which was at least three feet long. I reached down and rubbed it between my fingers, and it was thick and stringy just like my own cum, but clearer, and it smelled heavenly like thick, gooy honey. I quickly cleaned up and went to bed. The next day she smiled at me like nothing ever happened, and she and my sister goofed off just like they always do. I will never know whether she knew I was watching or not, but know that is one night I will never forget!
