Trampling and jumping on slaves body from the chair

Description: I like hurting my slave soo much! here i'm not only trample my slaves chest, stomach, groin and face as usual, but i'm jumping with full my weight on his ribs and guts from the chair! it's so hard for him to breath normally while i'm landing on him, making him to blow up all the air from his lungth, and trampling and marching on his chest and stomach really hard after that! when i'm tired, i'm sitting on the chair and making this bitch lick dirt from soles of my vans.
