Just after I turned 18 I did something stupid and was put in state prison. Had I still been a juvenile I would not have been sent up. But it's not like I planned it. I was big for my age and nobody messed with me in county jail. After I was transferred to prison I was assigned as a cellblock porter for my work detail during orientation. The detail sergeant was a retired veteran. He stayed fit and carried himself like he was still in the military. He was black and didn't show any favoritism toward black prisoners like others. One day he told me that he was going to make me a night porter for some projects. I was tasked with cleaning some storage rooms and offices. During count I had to stay wherever I was and he would guard me. The first couple of nights were normal. After that he started talking a lot about dicks, cocks, queers and other gay stuff. He said stuff like how many guys he has known to turn into cocksuckers after getting locked up. Several days later he asked me if I have got my dick sucked yet. He told me to be honest, it's nobody's business what's said or done between us. He then asked if anybody has wanted me to suck thier dick. I immediately said no. He shocked me by asking if I am interested in sucking a dick. He said it's okay, tell him the truth. I admitted that it has crossed my mind. He asked how much I peter gaze in the showers. I answered some. He then asked me what dicks I look at. I was too embarrassed to answer. At that point he pulled out a magazine from his desk and told me here are some dicks to check out. It was a gay magazine. Out of reflex I took it from him and checked it out. I had never seen a gay mag before. I forgot about him, I was getting aroused checking it out. When he spoke I realized that he was standing next to me. He asked me to show him a dick I like. I wasn't in the mood to lie. It was a black guy's. He asked if I peter gaze in the showers at black dicks. I was honest and said yes. He asked if I want to suck a black dick. I shook my head yes. He told me to say it. Being turned on I said I want to suck a black dick. He told me to tell him more. Being turned on, I let it all out of the bag. I told him that I have wondered how it felt to get a dick in my mouth. I like the idea. Ever since I got locked up I started fantasizing about it. I want to suck a dick. I really want to suck a black guy's dick. Without really thinking about it I blurted that I would suck his dick. He said say it again. I was getting off on talking about it myself. I said put your black dick in my mouth and let me suck my first cock. I was hoping that you would want me to suck your dick when you started talking about queers and cocks so much. I said make me a queer with your black cock. As soon as he pulled out his cock I did not hesitate sucking my first dick in prison. I engulfed it. I put my hands on his butt and made my fantasies come true. There was no way I was going to let him cum anywhere but in my mouth. In my fantasies what turned me on most was having a dick cum in my mouth. The real thing was even more amazing. Talk about super hot. After that I sucked his dick a lot. I confess that being put in prison turned me into a cocksucker.
