Princess Serena wanted this guy to wear a chastity device so she used her hot ass to make him wear it. She teased him before he came to her house. She did it on video and she managed to convince him to do some naughty things with him which he agreed. And when he wore it, he realized the trap he had walked into and he could not walk out of it without her. She then teased him some more and conducted all the experiments she wanted before she removed it for him.
