"Yara Frei, the leather-clad dominatrix, commands her slave, Cosmo, to kneel before her. In 'Preparation as a Toilet Part 5', Cosmo's training continues. Yara and two other mistresses take turns using his mouth and ass, spitting, pissing, and shitting on him. Cosmo's humiliation grows as he's forced to lick and clean every inch of their bodies, his cock painfully hard and ignored. Yara punishes him with a brutal ass-worship session, making him kiss and lick her boots, before finally allowing him a handjob, leaving him begging for more."
