A woman/girl who takes an exceptional amount of cum in every hole from pretty much any man who asks.
Emily is way to hot to be a cum dumpster but she let the entire sports team bust there loads in her so she totally is one now.

Any girl who takes loads of semen up her snatch, down the hatch, in her crack, and on her back. These chicks are down with the creampie be it anal or vaginal.

When a chick is sucking your cock and you notice insane amounts of jizz oozing out of her loose, overworked snatch. Because we are guys, we continue on face fucking her and dump the contents of our balls into said bitches gut.
Dude, really. Your mom is a filthy slut. I mean, she sucks a good dick and all but holy shit she's a total cum dumpster. How many guys do you think she fucked already today? I'm guessing by the amount of jizz i saw seeping out of her loose flappy twat and asshole, that she's been with 8 or 9 guys already today. Have a talk with her will ya?
