First Time: How I Love Cock

We were about thirteen at the time and I invited him for a sleep over. The basement where my Nintendo was set up had a fold out couch and when it got late, I suggested we could open up the bed and play while we were lying on the bed. I figured I could touch him under the blanket while we were playing to see whether or not he was into it and then go from there. Events played out just how I had imagined.
We were both lying on my bed playing video games. I slowly moved my foot up his leg while we were playing and he was so engrossed in the game that he didn’t think to stop me. I started to gently brush against his small soft penis with my foot and he shifted a little away, but I could tell he like the feeling. I gently rubbed him through his clothes with my foot and I could feel his cock getting harder. I was pretending that I was into the game and that my foot contact was incidental. He glanced at me and I just kept staring at the screen, so he felt comfortable to continue to let me rub his cock with my foot. He got hard, but was very small, so I could rub up and down his sweat pants against his cock with my toes.
I could see him getting flushed and he was losing track of the game we were playing. Eventually we had both stopped playing and I was jerking him off through his underwear under the blanket with my foot. I told him to pull his underwear down and I kept rubbing his cock with my foot. He was uncomfortable and asked what I was doing, so I just asked him if it felt good and if I should keep going. As he got closer to orgasm I wasn’t sure if he had ever even masturbated before because he was completely engulfed by it. He was lying on the bed with his head back and eyes closed. Eventually, I could tell that the moment had come, so I quickly pulled the blanket away. His eyes sprang open and he started to protest, telling me to stop, but as I put my warm wet mouth over his little dick his protests died in his throat and he started to have a body shaking orgasm. He filled my mouth with cum which drooled back out and onto the bed.
