Heard the guy's asshole expand. Promptly left the bathroom.

You ever walk into a public bathroom so quiet, you can hear a needle drop, or a man's asshole expand just before he farts/pees after sitting on the toilet?

Holy trauma batman

....yeah, that sounds pretty hot, I guess... if that's your thing you know, coo l cool

can't my asshole have any privacy?

what is the sound of a mans asshole expaning?

ass cough

i used to get on all fours and arch my back and suck air into my ass and fart it out

that was a good series of sounds.
