A chained man, muscles taut, struggles against his restraints, his cock throbbing with primal need. A woman, clad in leather and lace, circles him like a predator, her eyes gleaming with lust. She runs a gloved hand along his chest, down to his throbbing member, making him groan. She smirks, then produces a riding crop, snapping it against his thigh. He jerks, a mix of pain and pleasure coursing through him. She mounts him, impaling herself on his cock, and they move in a rhythm as old as time, their bodies slapping together, sweat mixing, as they chase their carnal release.
