Kick-Box training with the human punching ball

Description: I want to use this slave as my human punching ball - but since i know he always tries to use his hands to protect himself from my kicks and punches, i decided to bind his hands with a rope behind his back. this way, his whole body is unprotected and he has no chance but to endure the kicks and punches i deliver to his body! he's in quite good shape, but the sheer amount of kicks and punches takes a toll on his body quickly - and it doesn't take long until his whole chest and stomach is glowing red. towards the end, i take off the ropes, order him to get on all fours and deliver some final hard kicks to his stomach from below ... until he's broken ... until the next training session!
