First experience with a female
When I was about 13 I went to a friend's house, his parents and an aunt went out for the night and we were alone with his female cousin who was about 12 at the time. We began playing cards and convinced her to play stip poker. Of course she lost quite a few hands and soon we were all completely naked in an upstairs bedroom. My friend had a huge prick, about 9 or 10 inches hard, mine was only about 5' at the time, the girl, I'll call her Jane, was wide eyed looking at our hard ons, you could tell she had never seen anything like that before in her life. She was just starting to develop and only had small protruding nipples. We played around on the bed for a while, rubbing against each other until my friend could not take it any longer and went into the bathroom and jerked off, I was too overcome at just the whole event of being alone with a naked girl that I really did not do much but look at her while she admired my hard on. My friend came back and asked if he could mount her and just rub his prick on her pussy just to see what it was like, she said OK, but don't put it in me. He got on top of her, while I watched and humped up and down a few strokes with his huge prick rubbing against her hairless slit. A few drops of cum dripped onto her and she became quite worried and told him to stop. She was quite afraid of becoming pregnant. We put our clothes on, all very unashamedly, and I went home, I remember walking down the street with a raging hard on and immediately jerked off as soon as I got to my bedroom. It is amazing how innocent you are at that age, but also how curious both sexes are about doing what comes naturally if only you have the opportunity, and still don't know exactly what to do in a situation like that. It is self inspired sex education.
