This is the story of my experiences skinny deeping last summer
Last summer, when I was 14, I stayed at my friend's house for a week (they have a pool). My friend is a year younger than me, and has a really sexy sister the same age as me (I'll call her Sara). I was sleeping in my friend's room, and on the first morning he woke me up and took me to a small hole in the bedroom wall, where you could look into the bathroom. When I looked, his sister was just stepping out of the shower, dripping wet and beautiful, with no pubic hair (my friend said she shaved, and he watched her). I watched until she was dressed, then got dressed myself and went down to have breakfast.
That afternoon, my friend had a soccer game and a team party after, and since his parents were both at work, I was going to be alone Sara for the afternoon and until after supper. When he was gone, I decided to go swimming, and soon after Sara came out in a tiny string bikini, and joined me in the pool. We swam without talking for a while, and then Sara came over to me and said, 'I know that you were looking at me this morning.' I pretended not to know what she was talking about, but she kept bugging me until I admitted it. Then she said, 'I'll tell my parents unless you do whatever I say.' Since I had no choice, I agreed.
First she told me that since I saw her naked, she should see me naked. I slowly took off my trunks, and found that I had a raging hard-on. She stared at me, and since we were in the shallow end she could she everything. Then she told me that I should undress her, and I did, my erection now very ready to shoot. Once we were both nude, she reached out and grabbed my dick. As soon as she touched it, I ejaculated all over her. She gave a little gasp, then scooped some off of her stomach and licked it, and smiled. We swam naked until it was time for supper, which we ate naked, then got dressed before her parents got home.
I never saw her naked again, but we did talk about it often.
