Amber keeps her human punching bag locked in a cupboard in her basement and brings it out when she needs to release a little tension or just practice her martial arts training. She makes sure all the windows are shut so neither the neighbors nor her house guests could hear the muffled moans of the pain slut she holds captive. Amber belly punches her slave, but this is just a warm up for the ball busting which brings delight to Amber's face.
