Love the site.
I am very good friends with this girl my age. I've always been attracted to her but have never told her, as she is involved with one of my friends. Anyway, circumstances left me sleeping over at her house. This wasn't the first time, and her parents trust us.
I was sleeping next to her bed, and she was in her bed. She fell asleep.. but I was left incredibly horny. Slowly, very slowly, I pulled my pants down a little bit and masturbated as quietly as I could.
It was great, and she never knew about it. But it gets even better. The following morning I woke up a bit early, and, with my morning wood, I masturbated a second time, in the same room as this hot chick.
She never found out, but I am quite pleased with my little adventure.
