A latex-clad dominatrix takes her submissive through a journey of extreme belly expansion. She meticulously secures the submissive to a bench, then attaches the belly pump machine to their midsection. With each squeeze of the bulb, the submissive's belly distends, stretching their skin taut. The dominatrix's eyes gleam with sadistic pleasure as she continues to pump, the submissive's moans of discomfort and pleasure filling the room.
