Eva, a dominant vixen, teases her submissive partner Martin with a strap-on, promising to make him orgasm through his prostate. She commands him to remove his pants, revealing his chastity belt. She unlocks it, releasing his throbbing cock. She then lubes up her strap-on and slowly inserts it into Martin's tight ass, causing him to moan in pleasure and pain. She fucks him hard, making him beg for release. She edges him repeatedly before finally allowing him to cum, his body convulsing with intense pleasure.
