In the dimly lit dungeon, a bound woman eagerly awaits her machine mistress. The relentless fuck machine, its phallus glistening with lube, grinds against her pussy, making her squirm. She takes a moment to catch her breath, then eagerly engulfs the machine's cock, her lips stretched wide, as she deepthroats it with practiced skill. The machine's pistoning intensifies, fucking her mouth with wild abandon. Saliva drips down her chin, and her makeup runs, but she doesn't stop, pushing herself to take every inch.
