Probably work it a bit and if it responds with enthusiasm. wet my lips and suck it down. I'd jawjack it until it spitz!! If it was a really great cock I would certainly try to meet the guy for future meetings. But thoughts here where it is safe and the actual thing??? Who knows.

take that hot cock in my mouth and suck every drop of sweet nectar from it swallowing every last drop.

Worship that gift from heaven because it’s been s long since I found a glory hole to use.

when i would have to get down an start sucking it till he filled my mouth with his seed then i would wait till he leaves

Start massaging it to communicate that it's welcome in my stall until I can welcome it into my mouth.

Thank my lucky stars and start playing; I'd love for this to happen to me

Happiness. Excitement. Grab it, sniff it, taste it, then whatever happens, happens.
