Saw an image of this prank on pixiv and decided why not try to make a LoRa for this. Hands are not always generated correctly, but in general, it works as expected. The main tag is kancho, but the tags finger in anus or fingering can also have a positive effect on the generation. If you need to kancho through clothes, then the anus tag should be written in a negative prompt
