Nikki takes great sadistic pleasure in fucking up Nadman's balls, which are hanging completely helplessly down from above her. Nadman can't move an inch, suspended upside down in a tight bondage bag, with only his vulnerable genitals exposed, ready for vicious Nikki to play with. In spite of his predicament, Nadman is turned on by being in such a position, completely at Nikki's mercy. And she's not in a merciful mood!
