Mistress, a dominant MILF, teases her submissive with a massive, mechanical cock. She commands him to bend over, exposing his tight, virgin ass. Slowly, she lubes up the machine and presses it against his hole, making him squirm with anticipation. With a smirk, she turns it on, and the sub's cries of pleasure and pain fill the room as the machine relentlessly pounds him. The mistress watches, masturbating to the sight of her sub being ass-fucked.
