Mary Rider, the sultry dominatrix, teases in sexy lingerie, heels, and stockings. She slides a massive dildo onto her hand, eyeing her slave hungrily. His cock throbs, but she keeps him at bay, commanding him to stroke while she watches, her pussy aching in her pantyhose. She orders him to stop, her eyes glinting behind her glasses. He pauses, panting. She lubes up the dildo, rubbing it along her thigh, then pushes it into her slave's mouth. "Suck," she demands, "like you'll suck my pussy later." He obeys, eager. She pulls the dildo out, her fake cumshot coating it. "Now," she says, "only when I say."
