Tied slave humiliated

We are two nasty mistresses and the guy living with us doesn’t feel himself happy from such neighborhood! Do you know why? He is a young actor and at our place he performs the role of a slave! We think that we have already disheartened him and now pleasingly enjoy his disabled look as he sits tied up naked on the cold floor! It gives us a special pleasure to make this worm crawl and climb the rope or tickle his armpits and see his tiny cock getting even smaller! We really adore laughing at his shrunken pecker and that makes the slave even more humiliated!
