Mistress discovers a treat in her medical room. A bound, exposed bottom waiting for her to test out her new army boots on. The bottom's cock is tied into a wooden box, left flat and ready to be crushed under mistresses soles. After several minutes of agony, the bottom is given a moments break for mistress to change into running shoes. The bottom thought this meant he was getting a break, until mistress stood on his throat. This bottom love to be, and laps up his mistresses cruelty. This is his real life fetish, a real masochist with a real sadist.
