Cum Gush - When a man ejaculates inside of a woman's vagina just moments before she starts ejaculating (commonly called gushing, or squirting) both of their cum back out of her- and all over the place...
<Your Friend>: Dude, I dropped a load in your mom last night, and that crazy Cum Gush nymph sprayed my whole load back out at me like a fucking fire hose!
<Her Son>: Actually, that was probably like, seven dude's loads she sprayed you with!
