Mistress got a slave who was very devoted to her. He did anything she wanted and was always in the mood to play with the mistress. The mistress also liked playing with him. Today they were just going to play around and explore different fetishes. He kneels down in front of her and starts worshipping her legs. The more he worshiped her legs the more he got horny. Mistress forbade him from cuming fast and wanted to him to prolong the process. She reached down to grab and crush his balls and this action makes him cum on the spot.
