When I was in high school, my best friend's sister was so hot. She was one year younger than me, 15 at the time. I always thought about having sex with her and how good it would feel to touch her body.
Well, the laundry hamper was in the only upstairs bathroom. One day I dropped by to visit my friend and there was no one home. The house was always unlocked, and I let myself in. For some reason, I found myself in the bathroom looking through the hamper. I found a pair of red satin bikini panties.
I felt myself starting to get hard. I do not know how I decided to do this, but I went into her room and looked through her drawers. I found her panty drawer, filled with all different colors of satin panties. I pulled out a pair of green size five panties and took my shorts off. I laid on her bed and started to stroke my cock with the panties.
While I was doing this, I was looking at her pictures of her and her friends. I pumped for about five minutes before I blew a huge load of cum on myself. I did not want to cum in her panties as I knew I would get caught. It was the closest I ever came to being with her, but to this day I jack off with women's panties that I get.
