Sucking Other Men For Fun

I'm a 31 year old man who works at a trainstation shop that is quite well populated over the course of the day.
A lot of time older men offered me to fuck them, but i always refused until lately. Most of the men made really bad remarks, but not (lets call him Dave). He's a kind visitor at our shop and he always was asking for me instead of my stunning workmates. He loved seein my ass during summer shift hours, so one day i just invited him back into the office section of our shop after we closed down. It was the first time i invited anyone over after my latehour shift and i was just sucking him till he nutted on my face. We haven't seen each other since that but i hope he comes back and would be in for more
