^I'm not sure either. But it is probably self-insert OR it is the "defile beauty" thing. Seeing someone pure being defile by "something" gross is a fetish, from what I've seen on Pixiv at least. It is the contrast that seems to turn them on.

None of you must have seen the image of 4-5 fit women in bikinis posing at the back of a yacht with a caption that says something along the lines of "next time you see an image like this..." and then in the next image, the camera has been turned 180 degrees and now you see 4-5 fat and old men in speedos with their caption saying "... remember who paid for it".
