ビーチサンダルで踏みつける

Naked, my slave is tied to the bed, his legs and arms stretched out, so I can trample him without him being able to escape. I trample on him with my flip-flops and afterwards I use his upper body with my bare feet. I trample every inch of his body. I jump around on his belly and crush his willy under my weight. He starts shrieking and whimpering for mercy!
