A mysterious, unseen force summons a strapping, muscular man to a dimly lit room. The air is thick with anticipation as he begins to undress, revealing a throbbing, veiny cock that twitches with a life of its own. The man, oblivious to the unseen presence, strokes his massive member, his breath hitching as he imagines the demonic entity's touch. The room fills with the sound of wet, slapping flesh as he picks up the pace, his body tensing as he nears his climax.
