When I was about 13 a friend asked if he could suck my dick. And I let him, it was great. Over the next few weeks he sucked me often. Then one day he asked me to return the favour. Although I was hesitant I took his cock in my mouth. I was surprised at how much I enjoyed it. And he didn't warn me when he came. I battled to swallow that first time but the next time it was easy. We sucked each other regularly for about a year and then his family moved away. I have never seen him again.
