Hands trampling, push-up training, kicking and ballbusting and wight humiliation for a weak slave

I'm started with hands trampling for my slut, i'm walking, stomping, twisting and kicking his palms, then i'm sat on his back while he's standing on all fours and i'm continue kicking his palms with hard heels of my drmartens boots. but it's too boring... i love to humiliate my slave about his weight, he's not so fat, just a bit overweight, but he worries and complexes because of this and i love to remind him about it, humiliate him and i'm love hearing how he's apologizes for it to me, lol:) so, i thought up a little game to humiliate and remind him that he's fat weak peace of trash: he should pushing-up while i'm standing on his back. i've already know that he's wimp, but i couldn't imagine how much, cuz he can't even do 1 push-up! after few tries i'm punishing him: lot of kicks, cruel hands trampling and some realy painful ballbusting in this heavy boots. the order was 10 push-ups and i will receive it! he's trying to do it when i'm pushing him down with only one leg. he's succeed only in such way. his reward was a piece of pear from the floor: healthy food and exercises and i will make him skinny, cuz i love trample skinny body, it's much more painful for slave and that's the purpose.
