The Scat-Princess Mini Series comes to Part 6, where Nataly is the toilet slave of three girls, Sarah, Emma, and Michelle. Nataly is patiently waiting for them to finish their conversation so he can serve them his intended purpose. The girls, on the other hand, seem oblivious to his presence beneath their bottoms as they chat away, completely unaware of the discomfort and humiliation Nataly is experiencing.
As they continue their casual conversation, Emma accidentally farts, causing her to giggle awkwardly. This prompts Michelle to fart as well, followed by Sarah, each trying to outdo the other's fart noise. Amidst all the giggling and farting, Nataly can't help but feel humiliated as he catches whiffs of their odor wafting up from beneath them.
Soon enough, the girls finally notice their toilet slave's distress and decide to have some fun with him. Sarah tells him to clean her ass, and he complies, feeling even more degraded. Emma then tells him to clean her pussy, which he does using only his tongue. Michelle, enjoying the show, decides to join in and instructs Nataly to clean her asshole using his tongue.
Nataly obeys their commands, knowing that refusal would mean severe consequences. As he cleans their private parts, he can't help but feel even more disgusted with himself for his submissive role in all this. However, his humiliation is only increasing as the girls continue to use him for their own amusement and convenience.
Finally, the girls decide they have had enough fun for now and dismiss him, leaving Nataly to clean up the mess they have made. He wipes his tongue clean several times, feeling nauseated by the taste and smell of their waste. As he tries to collect himself and assess his situation, he realizes there is no end in sight for his humiliation and degradation as the girls' toilet slave.
