look up any word, like pussy:
 
1.
When a male ejaculates after a month or more of sexual abstinence and his semen flows without cessation from his penis as if he were pouring milk from a container. That’s “milking off”.
Damn, that woman is beautiful from head to toe. I would sure like to milk off in that ass!

Shorty got a bangin' body and a pretty face! I'll milk off and let her have my baby.
