Rusty Steamwhistle

A girl with diarrhea that's getting fucked in the ass then has a massive explosion that escapes under pressure around your dick.

Dude I was poundin your mom's ass when she let out a rusty steamwhistle and shouted "Quittin' Time Son!"

Moldy Steamwhistle

A blow job on a really dirty skanky penis. (most likely after a prolonged time without washing like a festival)

Oh man, After a week of camping with no shower at burningman she gave me a Moldy Steamwhistle!

At the end of the festival I got a moldy Steamwhistle from a babe
