If you lust after a vtuber's bust, face, voice or things they actually do on stream then they'll get self-conscious, thinking that maybe they came off to their audience as more provocative than intended, or were giving off the wrong idea with how they presented themselves. They may try to crop their avatar differently, or change their behaviour thinking that lazy, brainless coomers were just reflexively reacting to their content being too sexy, and thus denigrating the content creator to a two-bit pornstar.
But obviously nothing about a vtuber's model, persona or content draws attention to their ass. They know for certain that when fans lust over it, they aren't responding to something the vtuber is doing or showing, they're purely in their own imaginations, creating erotic fantasies of the vtuber for no other reason that because they like them. Because when the object of your admiration is purely fantasy, then it could be anyone. The natural question is, why Mint? Mint has never done anything to attract ass fetishists in particular to her. They could just as easily fawn over another popular indie or some big corpo channel.
Why Mint? Because they like Mint, pure and simple. They choose to make Mint the star of their fantasies because Mint is their favourite, so they just pair the things they like together. As a vtuber all you've done to get that kind of attention is be entertaining and likeable enough to make grown men fantasize about being with you.
Plus even as a fantasy nobody jumps straight to the back door unless they REALLY like the girl. It's a special thing you offer a special person, something that requires a lot of trust and cooperation and can go from good to gross really fast if that trust is misplaced. You don't tongue an ass you plan to say goodbye to, you tongue an ass when you hope it's the only ass you'll ever tongue. It's the horny equivalent to a flowery love letter--even if the attention is unwelcome the intention is absolutely flattering.
