Two brutal Mistresses want to get in shape, on the internet they read about body weight exercises. But I am not too sure it really works like this. They order a slave to the ground and just starting jumping up and down. He must be in a lot of pain. But these evil and brutal Mistress show no mercy. They take turns inflicting as much pain as possible. Why on earth did they not do better research on this bodyweight fitness movement? It really does not work like this. Slave can complain all he wants. It has no use, he must suffer.
