I'm gay and I blew my boss a blowjob.

I have to confess it to someone and I do it here because I don't know who to do it with. I had a threesome with my boss, I sucked it at the office.
I mean, I did one of those things I've always considered a slut. I don't know him that much and I don't have an affair with him, but the fact is that I blew him.
As in the most classic stereotype from porn movies, I put myself under his desk after "joking" heavily about sexual issues. He didn't waste much time and took advantage of the situation. He unbuttoned his flap and lowered his pants just as much as it needed to get him out. I dispossessed it until it came, not in my mouth but on the floor.
It lasted a few minutes, but my heart was in my throat worried that someone was knocking on his door.
Since then we have pretended nothing, every now and then he comments on the photos on social media as if to be remembered by him and to make me notice that he is always there willing to do it again. I don't have any desire and I regret doing it a little bit. Patience, it's been like this
