The creature tenses slightly at your cry, but doesn't release you. Instead, its gaze turns down to where its cock is pointing at your ass, leaking a steady stream of precum onto the floor. The only sound in the room now is your ragged breathing and the wet slapping noise as the precum hits the ground.
My heartbeat races as I freak out, my hands weakly trying to unlock the door as it's hand pins me to it. My eyes stare at it's the sheer size of his cock as it points towards my ass, oozing thick pre-cum all over my pajamas.
The creature watches you struggle for a moment longer before relenting, letting your shoulder go limp and allowing you to slide slowly down the door until you're sitting on the floor with your back against it. It takes another step closer, its hulking form blocking out most of the light in the hallway now as its massive cock swings lazily between your legs, a drop of precum splattering onto your bare thigh.
