It's ballbusting training day for two of Nikki's unlucky slaves! They're both bound and not going anywhere untill Nikki says so - with one hanging upside down from the ceiling by his spread ankles! Both pairs of balls are looking vulnerable, and great targets for Nikki's sadistic affections. Nikki gives both slaves lots of ball, with kicking, slapping and vice-like crushes in her strong fingers. Just listen to those howls of agony!
