For a femdom princess like Mistress Katjas, it doesn't matter how much a slave moans and cries. When he convulses in pain, it's just part of her fun. When he begs her to stop, it just tells her she's doing everything right. In this clip, the merciless girl jumps up and down, landing hard on his body with her feet and her ass while he begs her to stop.
She doesn't have a chair to sit at by her vanity table so she gets her boyfriend to be her human chair. Katja does her makeup and brushes her hair getting ready for a day at work. She doesn't care that her man's neck is throbbing from her sitting on it for so long. If he complains he will be sleeping on the couch tonight which means no pussy for him.
