I suppose I should write this ... I've always wanted to tell people what happened, so Here it goes...
This all occurred when I was about a senior in High School. I had a GF like most people and we fucked like wild rabbits...No biggie.. I had sex many many times with her and a few other girls through those years... SO I wasn't a beginner buy any means.
But there were things she wouldn't do.. anal, BJ, cum in her mouth etc that I wanted to try. She was more of a receiver, If you know what I mean.
I lived with my mom and younger brother, who is 2 years younger than I. MY uncle (let's call him Rob) stayed over occasionally with his GF. Now Rob was 9 years older than me and I assume his GF was too. His GF has long brown hair, her face was a 6, maybe a 7. She was about 5'7" and so she had pretty long legs I thought. Her thighs were thick and of course she had a very nice ass, and her were maybe 36-C's??
I don't remember where'd I'd been that day after school but when I got home it was about 7-8pm, not exactly sure. My mom was already in her bed for the night sound asleep. And my brother was in the living room watching TV. My uncle and his GF (call her Jill) were there also, they were in my/my brother's room folding some blankets or something. I said hi, and just grabbed some clothes and went off to shower.
When I got out of the shower (dressed of course) I went to the living room where my brother was sound asleep with the TV on. I turned it to ESPN to catch some sports news, highlights etc. After a half hour or so I went to my room.
My uncle and his GF had pretty much claimed the bedroom for the night I guess, which was fine with me because I had already assumed I'd sleep in the living room and watch more TV. My uncle and his GF were goofing off kinda wrestling under the covers and such. I sat on the edge of the bed and was trying to talk to him about something (probably school or sports)and she continued to play fight him and bite him and stuff..
Finally my uncle Rob said, "Help me get her please." So I playfully joined in and tried to hold her leg or something somewhat lightly. (This was only the 3-4 time I'd ever met her, so I was still new to her and I hadn't even spoken but a few words to her before.) She was on her side facing him, away from me and she suddenly fluffed the covers up and off of her as if for me to slide in.
Now, I was wearing some light gym shorts and a tee shirt, that was all. And when she flipped the covers up I could see she had on only a tee shirt (red) and a pair of red/black thongs. I tried to play it cool and just lay there as they continued play fighting and such and then she began to press her ass to me. It first touched me around my side/waist. I didn't move. She did it again, this time more of a wiggle and then press to me. I tried to position my stiffening dick away from her in case she was doing this on accident and didn't want to feel my teenage boner.
(I can tell more if you're interested )
btw, this is the 1st of 3 encounters we had
