As punishment for Her slave not being able to get an erection for Her amusement, Mistress Katherine decides to have fun tormenting his pathetic cock instead. Katherine first locks a Kali's tooth bracelet, which has several metal spikes on the inside, around the slave's cock, then proceeds to slowly tighten several screws with pointed heads right into his tender genital flesh. Of course, as She tightens the screws one by one with a special Allen wrench, She can't help but crush and batter his poor balls with Her hands - can't leave them out of the fun!

Mistress Katherine has been busy punishing slaves all week and is in the mood for some softer play. She offers Her slave the chance to play a game with Her - make his dick get hard and then go soft whenever She says and if he can follow the rules, he will be allowed to orgasm. Katherine teases the slave with Her beautiful tits and hot ass, even jerking off the slave Herself, but all he can manage to do is produce some precum, which She of course makes him eat off of Her fingers. Katherine informs Her slave that he has lost his chance for a reward and that She has the perfect toy to remind this slave that his cock belongs to Her.
