Wasn't, But Now Am BI

I was out with some friends from work. David and I are on the same projects a lot, while we were out that night, he was talking about all the guys he's been fucked by. David is a real slut it seems. Eventually around midnight it's the two of us. I was really with him with half a hard cock most of the night. I'd never had any gay sex and he knew it. I finally asked that if we were to do something together that it be kept between us and I not end up as one of his stories.

Soon I was naked with him, he sucked me hard then rolled onto his stomach in his bed and I got on and fucked him. It felt great, I'd never fucked a girl in her ass before this was a first for me, and never fucked a guy before, another first. He wouldn't let me reach under him and play with his cock during it though. After I shot off, instead he rolled me over and lubing me got on top. I didn't protest, though I really only wanted to try getting off in a guys butt.

The night ended with each of us having two loads of sperm up our behinds. I left and returned to my flat with my girlfriend sleeping in the bed. I showered and when I got in bed she woke up and started making out with me. She wanted fucked and even after twice with David, I was so horny thinking about it, I fucked her and after her second orgasm, I pulled up her legs and stuck it in her ass. She cooed, and told me how I was being so naughty. I came for the third time that night, up my girlfriends ass, all while having two loads of Davids cum in mine.

I've repeated that a lot since then. I fuck the gay slut then my girlfriend. On occasion I've gone from his ass, then to home with no clean up and smile while she is sucking my cock before I fuck her.
