The slave is used as a pony to ride Mistress around the dungeon. As part of his training to break his spirit. Mistress teases the slave with her ass telling him to sniff and kiss it. She is powerful and herself on top of him using her huge tits to hold him down. He is weak under her power. He is smothered by her ass and pussy. and her huge tits..........and a lot of cock teasing no relief.
