Mistress Kathrin wants to play with her slave today. Shes going to play a guessing-game and every time he doesnt know the right response hell get his butt spanked. Thats how Kathrin likes it - she loves to be in control and thats why she cuffed the slaves palms. She penalizes every false reaction with a severe hit of her railing crop - just like the slave deserves. But after the game she thinks the slave deserves even more spanking, she gags his mouth and starts beating him again. Then she gets on his back, makes him her human pony and keeps hitting him severely!
