I was 14 when one of my sister's friends came over to spend the night. We sat around, watched TV and played cards until about 1:00 am when my sister went to bed. We were sitting there playing hearts and talking about playing poker. She was just wearing a loose shirt and a pair of shorts.
We started a game of Strip Poker and the game is getting down to the last few hands. She had to remove her shirt and show me her breasts. They were still small, but the nipples were hard and sticking out. We were both down to our last item and I won the last hand. She removed her panties and sat back down on the floor. She was sitting there with her vagina exposed. It was the first real one I had seen.
I asked if I could touch it and she challenged me to one more hand for the right. I won and she let me rub the outer lips of her vagina. She had very full lips and a light covering of hair. She then asked how hard I was, as she could see my penis sticking out in my underwear. She challenged me to one more hand. If I won I could finger her and if she won she would get to see my penis. She won this hand, so I pulled off my underwear and my penis was sticking straight out. It was her first one that she had seen hard. She had seen her brother's a few times soft.
As we sat there, we began to talk about masturbating and she asked me how I did it. I told her I would show her if she would show me. She began to rub her vagina and opened up her lips. She was very wet and was leaning against the side of the bed. she rubbed for about 3 minutes and then came. She let me touch her vagina to feel how wet she was.
She said it was my turn, so I began to stroke my penis and did not take long. I was sitting right across from her and when I came my semen shot all over both of our legs and feet. She could not believe how much shot out. We sat there for about two minutes until my sperm began to run all over the place.
We met a few more times and she used to like me to jack off, so she could see my sperm. This lasted until they finally moved away a few months later.
