Balls stretched to maximum - Relentless CBT for ass kissing reward

I want to inflict as much pain as he can not take into this sissy bitch, masochist fetishist who wants desperately to kiss our divine ass. But he is in virtue and the key is between Lady Zara`s asscheeks. His balls are tied to the BDSM iron bad and he must reach it with every price while I whip his back with my Transylvanian single-tail whip... Do you want to be in his place? No pleasure without suffering. Remember this!!!!
