A guy does a girl up the butt and cums around her asshole. He thens motor-boats the girls asshole after she takes a shit. Cleaning up all the crusty poop and cum that is left there.
My friend kim, took a shit in the morning. Her boyfriend, dupree, came over and did her up the butt and jizzed around her asshole. After he stuck his tongue out and and cleaned up all the pooop and cum that was in between her cheeks. While this was happening her friend McCabe walked in and dupree spit out a crusty doodie in McCabe's eye. The girl kim then screamed out "Crusty McCame!"

Get the Crusty McCamemug. when a human, another human, and a walrus engage in a threesome sexual activity, once the walrus and man cum, they stop, then continue an hour from the previous orgasm to fuck the chick while shes crusty with cum.

Get the Crusty assmug. A person that is so horrific looking that no matter how shit-faced drunk you are at the end of the night you would never go home with them no matter what.
