Our parents had gone to a school reunion in another state, leaving my 10 year old sister and me in the care of an 18 year old cousin. The second day I heard her on the phone telling her boyfriend that “the brats” will be in bed at nine o’clock and for him to come over then. That made me mad, so I stayed awake just to bother her when her boyfriend came over. When she looked in, I pretended to be asleep. She also checked on my sister and went back to the livingroom. I waited until I heard her boyfriend come in and sneaked down the hall to see what they were doing. She was already out of her blouse and he was playing with her big titties while she had his dick out and was playing with it. He started to suck on her nipples and unfastened her pants. She pulled his pants off and got on her knees as started to kiss and suck on his dick. After a few minutes he told her to stop as he wanted to fuck her. She layed on the sofa with her knees up and he crawled on and started to pump his ass. Both of them were moaning, although they kept it quiet. Finally he stiffened and groaned that he was coming. He lay on her for a minute more and then rolled over. Although the light was dim, I could still see the come as it poured out of her pussy. I watched a repeat of their fucking, pulling on my dick at the same time. After they came that time I went back to my room and played with my dick until I went to sleep.
The next afternoon my sister asked if our cousin’s boyfriend had spent the night as she had seen him leaving when she got up that morning to go to the bathroom. I told her that he had not only spent the night, but that they had had sex in the living room. She said she didn’t believe me and I told her it was true because I had watched. Her eyes got big and she blushed but she still said she didn’t believe me.
The same thing happened the next night, except that there were two pairs of eyes watching. As soon as I saw that they were going to have sex, I went into my sister’s room and woke her. She was still half asleep as we crept down the hall, but she sure woke up when she peeked through the crack between the door and jamb. She backed up when she saw that our cousin was sucking his dick. Since I was behind her, this caused my hard dick to push against her ass. She only had on a shorty nightgown with a thin pair of panties and she immediately felt my dick against her. As she moved forward I followed and rubbed my dick against her crack. She reached back to push me away and her hand brushed against my dick which had come out of my shorts. She jerked her hand away but I caught it and pulled it back and put it on my dick. We had played around when we were younger and I had heard rumors that she had jacked off one of the boys at school. Those rumors must have been true because she began to rub my dick like she knew what she was doing. I reached around and began to play with her little tittie buds. When she began to rub faster and harder on my dick, I pulled her panties down so the head of my dick was against her bare ass. I immediately shot a load on her ass and down on her panties. Our cousin and her boyfriend had finished their fuck while this was going on and we slipped back down the hall. I followed her into her room and asked her if she believed me now. She said she could hardly believe that something as big as a dick could go into a pussy. I told her that it could and looked as though both of them had a lot of fun out of it. She looked at my dick, which was still hanging out, and asked me if I had ever done it. I told her I hadn’t but sure wanted to try. She said she did, too, which led me to suggest that we try it. She didn’t like the idea at first but soon agreed to. I helped her get her gown and panties off and discovered that she had a little bit of hair on her pussy. She laid on the bed and I played with her pussy and its hair for a few minutes. I had a hard time finding the hole with my dick and she ended up guiding it into the right place. She didn’t have much pain as she had been fingered before, but her pussy was still tight and oh, so warm and wet. Since I had already come, we fucked for about 10 minutes before I came. She didn’t come that time, but liked it so much that we had a repeat soon after. This time she stiffened and moaned and almost threw me off when she came. We never told our cousin that we had watched her fucking, but we both appreciated the lessons we learned. The next night we fucked in my room instead of watching. We have fucked ever since and don’t plan to stop anytime soon.
