A Cum Toilet is a girl who has been de-evolved into nothing more than a container for cum. It is quite literally what she is, as her throat, pussy and ass are used to deposit and leave cum. Apart from being considered a place where you can leave your cum, she is considered useless, and will only get cock in her if its to jerk it off in her holes before leaving her with more cum. It is not uncommon that a Cum Toilet end up becoming a Cum Addict.
