Bound and gasping, the submissive male awaits his mistress's pleasure. She teases him with her strap-on, running it along his thighs and ass, making him squirm. His hands tied behind his back, he's helpless as she lubes up and presses the head of the dildo against his tight hole. With a smirk, she slowly pushes it in, filling him. He groans, trying to hold back his orgasm as she pumps him, her other hand working his cock. She allows him to cum, but only once he's taken every inch of her strap-on.
