Musty Butt Fuck

You might find a Pugnant Bitch smelling this way. This smell might set off your Gaydar for it smells like a group of gay men just plowed each others sphincters. This must of the butt fuck stays for weeks and weeks, seeping slowly into every crack and crevice the must can find, you might be puzzled as to why this smell stays around. Maybe your maid (A Pugnant Bitch) had her late afternoon butt plow in your living room, grabbed her subway sandwich and stuffed it in her fat roll and kept working. could this be where this musty butt fuck smell came from? You will never know.

God it smells like musty butt fuck in here. (A crowded elevator in San Diego). Wonder why?
