I don’t remember how long after the first time I saw a girl naked. My younger sister was 7 and I was 9 but my sister at times would come into my bed and sleep with me. Probably because my bed was right next to the window and in the summer, there was a nice breeze. We would take turns scratching each other’s back by lightly dragging our fingers across the skin, or we would write words on each other’s back and try to guess what we were spelling. One warm summers night while we were scratching each other’s back my sister abruptly stopped and said that she wanted to “see my thing!” I was reluctant but she was insistent as she always is, saying that she would show me hers. With that she pulled down her pajama bottoms and showed me her young pussy. Well, the pubic mound anyway. I then reluctantly pulled down my pants revealing my flaccid little penis. That wasn’t enough for her as she asked if she could touch it. When I agreed she kind of poked at it for a few minutes then decided that she wanted to touch hers to mine. I remember now laying face to face with her and after a few futile attempts to touch privates in that position she told me to lay on my back and straddling me lowered herself to it while I held my cocks head up. She lowered herself until we made contact and once feeling each other, she got off. We dressed and fell asleep. It never happened again and we never spoke about it.
