Your roommate broke up with his girl two weeks ago.  Has not had a lot of luck hooking up since then. After fucking her every day for the past six months, he has definitely missed it over the past two weeks. Tonight he decides he needs to bust a nut into a tight, warm hole, or he is going to go mad. Unfortunately for you, he has determined that your hole is the one he plans to fuck. He has seen you checking him out as he walks around the apartment in his boxers. He knows that you will be unable to fight him off, even if you want to. So before the night is over you are going to have his nut inside of you. He is going to hold you down and force his eight inch cock right up your ass. Fucking you hard and deep, not caring for a moment if you want this to happen or if it hurts to have your virginity taken by a horny dude, just looking to bust a nut. You are nothing more than a place to stick his dick. He wont be gentle. He is fucking to dump a load, nothing more. 

This will not be a one time deal either.  Once he realizes how easy it is to have a cunt available for use at home, he is going to be fucking you all of the time.  You are going to have his cum dripping out of your ass seven days a week. Anytime he is not hooking up with a girl, he will be spreading your legs. 

You are going to be his fuck bitch from now on.
