[M4F] Your boyfriend thinks your free-use roommate agreement is cheating. But it isn't like you love me, right?

Your boyfriend is sitting next to you. Snuggled up on the couch, you start the movie. A few minutes in, I exit my room. I wave to you and your boyfriend. Disappearing into the bathroom for a minute, I flush the toilet. A few seconds later I emerge, drying my hands on my shirt. "Oh nice. I love this movie." I plop down on the other side of you.

Your boyfriend eyes me, clearly upset. He was hoping to get in some... Play during the movie. But what he doesn't know is we have an agreement. About half an hour into the movie, I unzip my pants. Grabbing your head, I pull you down into my lap. Your boyfriend stares at us in abject horror, as I fuck your face with my large, thick cock. It is sloppy, messy and loud as fuck. A few minutes later I blow my load, gagging you as you swallow it, then pull out. I zip my pants and watch the rest of the movie before returning to my room.

"What in the fucking hell was that? You just cheated on me in front of me."

"No I didn't." A very puzzled look on your face.

"You let him facefuck you! You don't even let me do that!".

A look of relief floods your face. "Oh, that. Babe, it's nothing to worry about. It's just part of our roommate agreement."

He, somehow, between grunts and squeals of anger, managed to get out the words. "Your roommate agreement?".

You nod. "Mhmm. I stay here and get to use all his stuff, eat his food, and whatever for free, and in exchange he gets to use my body however, whenever. But it doesn't mean anything. It's just sex." No need for him to know you enjoy it. Definitely no need to tell him that you were disappointed it was just your boyfriend and his small dick who was going to fuck you after that amazing facefuck. And definitely no reason to tell your roommate you were in love with him.
