After having some fun at the beach my cousin(18) and I(19) went back to my house to sleep. She stayed the night because it was late and she didn't want to drive all the way home. There were no extra beds or rooms so she decided to sleep on the floor in my bedroom. This was a normal thing and she had slept in my room many times.
I got ready for bed in the bathroom and came back to the bedroom to lay down. At this time my cousin went into the bathroom to get ready for bed. Since I always sleep nude I slipped my clothes off and got into bed under the covers. A few minutes later my cousin came into the room with one of my T-shirts on and my boxers on. I could tell she had no bra on and she was carrying her thong in her hands. Her cup size was 34c. I knew this because I had done her laundry before and curiosity got the best of me so I look to see how big she was. This turned me on extremely because I already thought my cousin was hot and now she is wearing my clothes. She said she had no extra clothes and laid down on the floor next to my bed.
We watched T.V for about 30 minutes and then I turned it and the light off. About a minute later the light came back on and there my cousin was standing completely naked at the foot of my bed. she was completely shaven and looked stunning. She then climbed on my bed and ripped off my covers exposing my almost erect five and a half inch cock. She then began to stroke it. I was so surprised and turned on that I could barely contain myself. After a short while I exploded and my hot cum went all over her face and my chest. She licked up every last drop and turned the light back off and went to sleep.
The next morning we were still naked so I fingered her after she woke up. She jacked me off one more time and then left.
I am now 24 and she is 23 we both still hang out a lot and every once in a while we get freaky but that night was the best orgasm I have ever had.
