Mistress Maria caught her slave being naked in her house. She had warned him against it as it was perverted but he did not change. And she was in no mood to make him change. So she trampled him, used him as a human pony and lastly, the mistress forced him to endure painful whips to his naked body. The guy never walked naked outside his bedroom as he knew what would happen.
Mistress Maria and this guy were watching a movie together when he got to a point and he wanted to smash her. She did not think of him in that way and she was shocked. But she could see he was suffering so she facesat on him for her own entertainment and she jerked him off for his own fun. For mistress Maria, that was a win-win situation. She left when he came.
