I'm looking for doujins or comics that prominently feature BBWs or MILFs getting taken down as a form of comeuppance for the protagonists.

From what I can remember, the doujin involved two girls. One tormented and humiliated the other. One girl would tie up the other girl, then would inflate her belly with a shower hose through her anus. The girl with the inflated belly would squeeze the fluid out by herself or by force.

I believe the author made a series out of it, with two that were already released, either translated or untranslated.
