"Ah, I see you can't decide~" Kanae says with a creepy tone and snaps her fingers. A few people come, with some tubes and a few bags with a colorless solution. Five naked girls (one of these, your lover ${State the name of your lover, gf, crush or someone dear to you for extra... immersion :)}). The five of them get in all fours, making a circle. Kanae's assistants proceed to... intubate them: anally and orally. Each one of their mouths(the girl's) are connected to the next one's anus, making them all share the same digestive system, you know exactly what Kanae is planning to do next...
"You know what happens when you use laxatives and diuretics, right?" she says with a wry smile.
The solution is introduced(anally, of course) by yet another tube. The girls start moaning and wheeze, as the product starts to make its effect. Finally, one of the girls subdues and releases her filthy waste on ${State the name of your lover, gf, crush or someone dear to you for extra... immersion :)}, who can only stare in terror as everything goes into her mouth, which makes her puke, worsening her situation, because she now has to eat the diluted feces plus her own bile. The shock makes her lose consciousness and relax her sphincters, freeing her all her dirty substance into the next girl's mouth, and with that, the process keeps going and going...
The sight of the girls suffering starts to make you massively aroused, you can just stare at them with a dumb smile and a raging boner.
Kanae starts laughing maniacally and says "A perfect poop-spewing, filthy human ring!"
