Sorry I can't help you. But while I'm here, maybe some kind soul could translate this hentai.

https://exhentai.org/g/1311456/1e4c43f540/

It has scat, enema, ryona, humiliation, a lot of things that are appreicated here, and no translation yet.

From what I understand, this girl get bullied by other girls who give her an enema and make her swallow a bunch of laxatives at the same time, and her stomach goes crazy and maks noises, something which I find hot as fuck.
