Hard and painfull trampling in DrMartens with lots of jumps

Description: Here i'm trampling my slaves back firstly. i'm marching on his back and injuring him with sharp edge of the sole, but most of the time i'm jumping on him and trying to land as hard as i can here (i'm not comfortable holding on and i don't want to fall from my carpet). i'm making him thank me and kiss my boots, then i'm kicking his ribs as well. in the end of the vid i'm trampling and jumping on his chest and stomach too.
