After watching their dominant mistress Tiffany perform an incredibly intimate act with a human toilet, Slave B and his fellow male slaves are left feeling aroused and humiliated. As part of their training, the mistresses decide to give the male slaves a chance to experience pleasure by allowing them to touch themselves.
But things quickly go awry for Slave B. He becomes so overwhelmed with excitement that he orgasms prematurely, disappointing his mistress. Humiliated and ashamed, he tries to clean himself up but is stopped by one of the other mistresses who tells him he's going to have to taste his own cum.
Feeling defeated and dirty, Slave B looks on as the other male slaves continue to pleasure themselves under the watchful eye of their mistresses. However, the situation takes a turn for the worse when the girls decide they need to relieve themselves and begin taking enormous shits into the toilet.
Amidst the filth and stench, one of the girls grabs Slave B by the hair and forces him to open his mouth. With a wicked grin, she tells him that they have decided he won't be leaving until he's tasted all of their feces. As the girls take turns shoving their excrement into his mouth, he chokes and gags, unable to believe the depths of their depravity.
Despite his protests and pleas for release, the girls continue to use him as their personal toilet, laughing cruelly as they fill him up with their foul-smelling waste. Throughout this ordeal, Slave B feels utterly humiliated and degraded, but he knows there's nothing he can do to escape his fate.
