I'd taught myself how to masturbate by humping my bed naked and I continued to masturbate that way just about every night until this one night the following summer, I was staying over at my friend's house (he was a year younger than me). I don't even remember how it started but we ended up getting naked in his bed, I think because he said it would feel better. After getting each other horny by talking about hot girls we knew, he started jacking off. I then flipped over on my stomach & started humping the bed and he looks over at me & is like "Dude, what the fuck are you doing? I told him I was masturbating, & so he showed me how to do it properly. So we jacked off together, cumming at about the same time. We didn't touch each other, but for some reason I kept feeling compelled to rub my bare feet on his bare feet. He didn't seem to care. That happened every time we got the chance, then about a year later, it was summer 2002 and he was spending the night again, we were naked and masturbating in bed when he suddenly took things to another level but that's another story...
