人体打手袋。女主人的日常生活是用受虐狂作为拳袋来训练她的身体，缓解压力

The Mistress puts on boxing gloves and begins her daily training, using the masochist as a human punching bag. The Mistress fires punches and kicks at the masochist's body, and when one hits his face, he collapses to the floor. As the masochist falls to the floor, the Mistress stands on his face with both feet and crushes his face with her knees. If the masochist stands up, he is punched and kicked, and if he lies down, his face is crushed with feet and knees, so the masochist has no way to escape. The Mistress grabs both of his hands and puts the soles of her feet against his face, crushing it. The Mistress' target becomes the masochist's balls, and when she kicks them with her feet, he falls to the floor and writhes around. Every day the Mistress uses the masochist as a human punching bag to strengthen her body and relieve stress.
