Miss M, the sadistic domina, has her slave P caged and pussy-free, ready for another round of training. Today's lesson: anal with a sex machine. She leads him around the room, his naked body on display, before securing him to a St. Andrew's Cross. She clips nipple clamps onto P, making him wince. She grabs a Hitachi wand, teasing his cock until it's rock hard, then denying him release. She lubes up a large dildo, pushing it into P's ass, stretching him. P groans, his body tensing. Miss M smiles, enjoying his discomfort. She attaches the dildo to the sex machine, positioning it at P's ass. As the machine starts, P's body convulses, his moans filling the room. Miss M watches, satisfied, as her slave is fucked into submission.
