[F4M] Your roommates girlfriend

You hear the front door unlock, a bit of fumbling, and then it forcefully shuts. This routine has become a weekly occurrence in the apartment. Soon after, my loud moan echoes through the hallway, prompting you to peak out from your bedroom into the dark living room. By now, my boyfriend has me pinned firmly against the wall, his mouth aggressively leaving marks across my skin to claim me. Our eyes suddenly meet across the dim space, mine looking completely bored and emotionless despite the fake cries of enjoyment I keep feeding him.
He hikes up my dress and pushes his way inside me. This time a slightly more genuine sound escapes my throat, since I am only human after all. I begin chanting his name in his ear, playing up my excitement once again to speed things along. I want this encounter over with quickly because the sooner he finishes, the sooner I can make my exit. Yet my gaze stays locked entirely on yours as a sudden shiver of real desire hits me. I have always harbored a secret crush on you, and knowing you are watching me get taken by him is incredibly thrilling.
My boyfriend thrusts a few more times before I feel him release inside me. Taking that as my cue to pretend I finished as well, I play the part. He slumps forward with a quiet laugh, gives me a quick kiss, and then slips out to head straight into the shower.
While your roommate is occupied in the bathroom, perhaps you can step in to help me out properly?
