The other night, my friend John had been sleeping over. We are great friends and have known each other for several years, and as such, we tend to have a lot of 'perverse' conversations. This particular evening, he had suggested downloading some porn, nothing for that night, but for my future reference. A few hours later we decided to get ready for bed, and found that the porn had finished downloading. We were both rather tired, so we didn't think about watching anything. However, before I jumped into bed, I zoomed through some of it to see some amazing sex scenes and some rather gorgeous women.
Once I had hopped into bed, we began talking about rather mundane things. Games, school, books. Oddly enough, not a single thing about sex or masturbation was mentioned. However, I suddenly sprang a hard on, and after 20 minutes, it would still not go away. So I did what any normal red-blooded American teen would do.
Slowly, I started stroking my dick. Since I didn't want to alert my friend of my activities, I only used three fingers and limited movement, and kept the conversation going. It wasn't till later I realized that my slow pace and caution was almost like edging. More and more I built up to an orgasm, when suddenly my friends head (The one with eyes, people.) popped up from the foot of my bed. I was petrified that he might have seen me, but he said nothing, and he just kept on talking.
After another half an hour of slow, almost agonizing stroking, I came with seven large ropes of cum that splattered onto my short bottoms. My friend and I said goodnight, and I fell into a deep and very satisfying dream. Maybe if I had more guts I would have asked my friend to join, but just the thrill of the possibility of getting caught was awesome in itself.
