Two nights ago I got wasted with my co-worker/friend Tom. He's 22 years old, hot as fuck and for the 3 years I've known him, he was as straight as they come. He's always known that I was bisexual and seemed cool with it, even if he did make a few jokes about me now & then. Anyway, we got drunk the other night and I ended up sucking his dick. It was fucking great at the time! He didn't reciprocate or anything, he just sat back on my sofa with his hands behind his head while I knelt and sucked him, but that was ok with me. He came in my mouth, then quickly jumped up and called his friend to pick him up -- he was out the door right after his phone call was done.
I'm starting to think that even though I got to mess around with this guy I've wanted for years, it might have been a mistake because at work yesterday he barely spoke to me all day. Things seem weird now and I don't know what to do. He was the one who initiated things by talking about how he needed a blowjob and then asking me if I wanted to suck his dick. Maybe he's afraid I'll tell someone, maybe he just feels awkward about it. What can I say to clear the air about this with him?
