When I was 16, a stiff breese could give me a hard on. It really didn't take much. I thought I knew everything there was about how to get it up and get off.
One day as I was emptying the trash, I found a pair of nlons my mother had thrown out because of a run. They felt so sheer, I put them in my pocket. Later that night, after everyone had gone to bed, I slipped them out of my drawer and put them on. They felt so sheer and sexy. I had the hardest erection I ever had (until then). I started rubbing my cock through the sheer nylon. Pretty soon I came.
Since then, I wear nlons and stockings every chance I get. They give the best erections. Adding a bra and panties helps me get off even better!
