In an intense, real-life couples' game, Mark finds himself naked and restrained, at the mercy of his girlfriend Kelly. She wields a leather belt, her eyes gleaming with dominant intent. Mark's ass cheeks quiver in anticipation as she cracks the belt against his skin, leaving angry red welts. Kelly's breath hitches with each slap, her own arousal evident. Mark grits his teeth, counting each strike, until he can't take it anymore. "Stop!" he finally cries, his voice raw and hoarse.
