A woman who loves to have a man cum inside her during sex instead of pulling out or cumming in a condom (i.e. likes it RAW!). She always wants it that way, every single time, and it's a big turn-on for her. It's even more of a turn-on for her if she's not on birth-control (risky sex is fun sex). The more cum is in her, the happier she is.
Every time Jerome fucks Susie, she begs him to cum in her. She is SUCH a cum-dump.

Cum-dump is a common term for a true slut. This kind of woman insists on having as many men cum in her mouth, pussy AND asshole as possible. She begs for it and insists that no rubbers be used. She enjoys being called and treated like a total whore.
Kathy is a true cum-dump. Over the weekend over 15 different men came in all three of her slutty holes. She kept scooping cum from her pussy and ass and wiping it on her face and licking her fingers
