Trampling slave's body and face and jumping on him from the chair

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