Mistress Iside - DESTROYED BALLS AND ERECTED COCK

Today I’m in a good mood and I have decided reward this slave for his faithfulness but, first, I want him to undergo a very hard test. This slave will have to keep a constant erection while I’m going to hit his balls with my extremely powerful kicks. Of course, he already starts trembling, he knows very well that I’m not going to have mercy of his flaccid balls but, if he wants to earn his prize, he needs to make every effort and offer his suffering to his Mistress. Will he be able to pass this horrible test?
