Fuck your Brains out 

To fuck for a long period of time..... Quickly. As in thrusting fast for hours. To make both man and woman climax multiple times in an hour. To make a head imprint or dent in a headboard.

A fun weekend, to Fuck your Brains out with sarah!!

Fuck your brains out 

One of the best orgasmic sexual experiences you will have with the opposite sex it’s hardcore and savage riding and thrusting and humping making each other’s head go back again and again like wild animals the best kind of sex

(Whispers in her ear)
I will fuck your brains out
