I was sleeping over my friends house for the weekend. His parents were away for the weekend. We were watching TV downstairs and eventually everyone fell asleep. I went up to use the bathroom and noticed my friends parents door was open. I took a look in and eventually found my way to his mom's pantie drawer.
I checked out all the different colored thongs and g-strings. My dick was the hardest it had ever been. I took out two pairs of panties, a white pair and a red pair. I wrapped one around my dick and the other in my mouth and started wacking off. I increased my speed and felt my orgasm coming. I exploded all over my chest and on her panties. It was pure ecstacy. I have been doing this for two years now. I want to somehow find a way to tell her about my fetish and get her to watch me doing it. That would be HOT.
