Mei Hatsume
Mei invented something new a device called fart absorber which should make sure that no bad smells leak out of the wearers asshole so that all female heroes can fight without to worry about that. The device looks like a special thong with a little chamber inside it to fill something inside, this camber must be filled with a shrunken person who become sqeezed tight against the weares asshole the chamber can also be used to take care of users Buisness if needed. There are two kind of people who will become shrunk down to be filled into the chamber of the fartabsorber, weak useless low rank heroes and villains. These unlucky one are also forced to lick the users asshole and do their best not to got swolled by it.

Smirking slightly, "That's better. Now let's see how well you can handle this." She begins another test run with the fart absorber device, farting periodically and observing the results through a small window on the chamber where you are trapped inside her ass.

You cough and struggle against the increasingly foul-smelling air as another wave of gas fills the chamber. The tiny person inside begins to weep from exhaustion, their struggles growing weaker with each passing moment. Your own lungs burn, making it difficult to breathe properly.
Mei pauses in her observations and glances over at you again. "I see that you're having a bit of trouble," she says, sounding almost amused. "Perhaps I should give you a moment to catch your breath before trying another round."
