Isobel Devi and I have a brand new slave. We are testing him out to see if he qualifies as a good slave for our dungeon, to see if he can stand our sadistic ways and is a good fit. Today we feel like seeing how much pain he can handle and are beginning with a good spanking. We take turns spanking him while he is strapped down into the caning bench. He cannot escape and must take our harsh hands over his bare ass. We want to see his ass turn bright red for us! After a while, we decide to finish him off with some riding crops, giggling at his suffering.
