I kinda wish they'd drop the slut joke. Its kinda getting annoying.
Unfortunately, it kind of comes with the territory. This is an ENF/humiliation fetish manga, so that sort of thing is basically just meant to be fun dirty talk
That being said, yes, the more they do it, the less impact it has. Honestly, at this point they should change it up a bit so people are celebrating her nudity as part of her heroic brand, which could be just as embarrassing in its own way
