A strapping straight man is bound in elaborate, leather restraints, his muscled body tensing as he's laid out for his mistress's pleasure. His eyes flutter closed, a moan escaping as she traces a latex-gloved hand down his abdomen, pausing at his hard, leaking cock. With a sadistic smile, she bypasses it, instead lubing up a thick, curved anal probe. His breath hitches as she presses it against his tight hole, sliding it in with expert ease. She expertly probes his prostate, making him squirm and beg, but she denies him release, edging him to the brink again and again.
