cock lock maneuver

When a man is about to pull out of a woman's vagina because he doesn't want to get her pregnant and the woman then wraps her legs around the mans waist and forces the man's penis inside of her repeatedly until he cums; usually causing pregnancy.

Guy#1: Dude I heard you and Cassandra in the bedroom last night sounded like you guys had a good time.

Guy#2: I don't want to talk about it....

Guy#1: Why?

Guy#2: She pulled the cock lock maneuver on me...

Guy#1: Wow.... sorry....
