I worked in an office that occupied 2 floors, 17 and 18. We couldn't access the stairs so we had to use the elevators. On 17, we only had part of the floor so, on that floor, we used common rest rooms near the elevator.
My office was upstairs, and, when I had something to do downstairs, it was convenient for me to stop in the mens room on 17 on my way to the elevator.
One time, one of the young men (20s) who worked on 17 entered the mens room shortly after I did, stood next to me, and pulled out what looked to be his erect penis.
I'm no prude, and I've had my share of sex in public places, but I was management and actually liked this job, so I ignored him, finished what I was doing, zipped up and left.
I'm in my 40s, and nothing special, so I figured maybe it was just my imagination, maybe he just had a big dick and was holding it in a way that made it looked hard. Other than thinking the kid was lucky for having a big one, I didn't give it another thought.
Anyway, a few weeks later, the same thing happened, only this time he made it quite clear he was interested in some action. I mumbled something about being late for a meeting and left.
That afternoon I sought out a gay colleague who worked on the 17th floor and told him what happened. 'Oh yeah', he told me, 'the same thing happened to me.' 'What did you do?' I asked. 'My colleague shrugged and said 'I let him blow me', in a manner that made me feel like an idiot for even asking. And then, he went on to devastate me by adding 'He'll blow anybody. Good little cocksucker too. You should let him do you.' All this in a tone that could be used for recommending the pot roast in the company cafeteria.
I never did let the guy blow me (I was in one of my monogamous phases). A year or so later, I heard through the grapevine that the cocksucker was leaving for another job so I dropped by his desk to wish him well. We both ignored the obvious.
A year after that my company went out of business. Two years after that, my relationship (the monogamous one) ended. In retrospect, I suppose I never should've turned down the BJ.
