OK here is a true story...
When I was 16 I started working out and was quite proud of myself I guess. I had the greatest 6-pack, my arms weren't so big, but I was pretty built for 16. My friend zack was over and we were laying on the floor watching tv when I pulled up my shirt and started rubbing my belly and chest while I was staring at the tv. I don't know why I did it I just did.
Zack said, "Looks like you have been working out."
I said, "Yeah, feel."
He got down on his knees next to me and started pressing my stomach feeling my hard muscles. Then he said, "Looks like that's not the only stiff muscles you have."
I was wearing grey sweats cut off at my knees and boxers, and a white t-shirt. He started dragging his pinky under my waits band and I don't know why, but I just laid there and stared at the tv. Then slowly I started groaning in pleasure as he rubbed my stomach and chest. He touched my nipples with the tips of his fingers and they started getting all stiff. I was in heaven but didn't want to be gay and didn't want to make him stop, so I just laid there and let him reach down in my boxers and pull out my now stiff and dripping cock. He didn't do anything but look at it and rub my tits.
I finally said, "Look you started this, now you finish it."
He took my cock in his mouth immediately and sucked me hard. I was moaning and started fucking his face. I held the back of his head with both hands and kind of rolled over on my side and started fucking him good.
I came in about two minutes. Zack choked on the cum and spit it out all over my cock and it dripped into my pubic hair and on my boxers.
When I was done I pulled up my shorts and he went coughing to the bathroom. He spit and coughed and came back saying, "I didn't think it would taste like that. Yours tastes a lot different than mine."
I just laughed, called him a bitch and told him I wasn't gay.
He said, "I'm not either. Haven't you always wanted to try that?"
I told him, "No. But I want to try it after that."
Anyway that was my first time with a guy. Hell, that was the first BJ I ever had. And I got plenty more from Zack -- he learned to swallow.
