There's this guy that hides in bathrooms and he steals your poop if you don't flush. So, you better flush.
My mom told me about him, when I didn't flush.
Mom - "Be careful, Jim"
Jim - "Why?"
Mom - "There's a poop robber might be in the bathroom and he might try to steal your poop if you don't flush. So, you better flush."
running your dick between somebody's ass cheeks after they've taken a shit and rubbing your shitty dick on their asshole without attempting any actual insertion.
Wipe fuck me before my shit gets cold, Carlos.
