Went on grindr and found a work-local fuck buddy online - messaged asking if he'd meet me in the toilets of an office buidling at the top the street we both work in, he replied saying yes. I said 'normal procedure' and left work, saying I was off for a coffee. Went into the toilets, two minutes later he came in, cleared his throat twice (our signal) and I let him into the cubicle I was in. He dropped his pants and got his thick cock out, I sucked his cock to completion, and he left. This man is a heavy cummer, so filled my mouth with his load. Two people walked in and used the cubicle next to use while I was sucking him off.
