In my last job I had a couple:
One guy in the graphics department used to blow me a lunch in the WC when I needed a quick unload but best was he skinhead marketing manager! I knew he was a gayer but thought nothing off it as we didn't seem to get on however one evening I was on gaydar in need of a load dumping in me and spotted a profile and thought to myself that looks like skinhead, noting he was top and play safe sex sometimes!
He spotted my track and massaged with a clear undertone of - fancy a fuck?
He unlock his pics and he had a nice fat 7.5" uncut tool and with that I gave him the address, unlocked the door, lubed my hole, bent over.
I heard the door go, nothing was said in fact we didn't even look at one any other for the whole fuck! Next thing I knew his cock was in me bare and after 10 minutes of a very hard fuck, he rammed home and unloaded. He just pulled out and left.
We never talked about bareback or status...which if you're going to fuck raw is the way it should be.
Following day, I was sat across the table from him in a meeting fighting over a project like nothing had happen but getting back to my desk I had an email off him telling to me to be ready at 6; and he just turned up, loaded me up and left.
Went on like this for about a year - every time we had a meeting he wanted to fuck me that evening, even came with a mate now and again but no idea who it was till this day as never looked and we never talked about it.
He left the company and it came to an end
