I crushed my slave with his bare feet barely, until I covered his cock with the sole of his feet and rubbed his cock with my toes.
For me he and his genitals were like a worm that had to be trampled on to pulp, so I trampled on both his balls, which I wanted to crack and the cock from which I wanted to make a shred. And my slave looked closely at the delicate toes, which crushed his top with full strength and powerful heels that rubbed his genitals.
