I was thirteen in the locker room at school after gym all of us boys were getting dressed and there was this one kid who was talking about blowjobs (and just to be clear I did always kind of find this boy attractive and I’m a boy). All of a sudden he looked at me and said “Hey I’ll give you twenty bucks if you suck my cock”. My first instinct was to say no but I don’t know if it was hormones or if it was just because I thought he was cute but a yes just popped out before I could stop myself. He looked shocked at first but he just said ok and whipped out a decent sized cock (can’t tell you exact size). I kind of just stood there awkwardly until he told me to get on my knees and suck so that’s exactly what I did. I started by putting his dick in my mouth and moved my head back and fourth. Afterwards I took it out of my mouth and began to lick it. I could tell that at this point he was trying to hold back his moans. I started getting into a cycle where I would suck his cock for a while and then I would start to lick it. Eventually while I was sucking it the boy put his hand on the back of my head and shoved his dick deep into my mouth. I wasn’t sure what he was doing at first until he let out a big moan and I could taste his cum in my mouth. Being a little bit in shock I pulled away from him and I spit his cum on floor. After that our gym teacher called from the hall “what’s taking so long in there!” We hurried to clean up and get ready then we rushed out of the locker room. On our way out the boy handed me twenty dollars.
