When I was in college, I had a neighborhood friend Rich that was a couple of years older than me. I was friends with his family (I actually had the hots for his younger sister). I kinda thought he was gay from the way he acted and some of the things he'd say, but he wasn't "out" yet. We all called him Big Rich because not only was he tall, one time while skinny dipping in the lake we all saw his cock and it was absolutely huge, at least compared to ours. The nickname stuck i guess.
Rich's parents went away one weekend, and we were bored so we decided to hang out at his house. There was nothing on tv, and Rich suggested a porno he had gotten his hands on. It was straight porn, and as we were watching, he started to rub himself, so i started rubbing myself. He pulled his cock out and started jerking himself slowly. His cock was a man's cock, thick and long. I've played with guys a bit here and there, so I was no amateur, but I didn't want him to know that. He said go ahead, so i did the same. The porno got hotter with lots of sex and fucking, and we were stroking our cocks furiously. Rich suddenly stopped and said if he kept it up, he was going to cum. He told me if i had to cum, to go into the bathroom and cum in the sink. I stopped and my hard on was upright like a flagpole.
After some time, Rich asked if I ever touched a cock before, and i lied and said no. A few minutes later, he reached out and grabbed my cock. He held it for a while, then started stroking it. It felt really good, so I reached out and grabbed his cock and did the same. We sat there for a while, just fondling each others cock. Since I didn't want him to know I had done this before, I just mimicked his steps, let him lead the way, and think this was all him.
He then asked me if he could suck my cock, and I said yes. He leaned over, licked my cock, put it in his mouth, and proceeded to give me an amazing blow job. I told him i wasn't going to last long. He didn't want me to cum in his mouth, so when i got close, i pulled out and ran into the bathroom and came in the sink. When I came back, he was a bit redfaced and embarrassed. I said its ok if we don't talk about it. He seemed happy about that. Little did he know I had plans for more fun.
For some reason, I can't even remember why or what drove me to do it, i walked right over to him, dropped to my knees, leaned over and put his cock in my mouth. He was shocked. He asked if i was sure, that I didn't have to just because he blew me, and I told him i wanted to. I sucked him like a pro. He told me he was going to cum and I kept my pace. He started to panic and said he was cumming. I locked onto his cock and swallowed every drop. When I was done, i leaned up and looked him in the eyes and he was completely taken back. He said it was perfect.
