This LORA was made with the purpose of generating those gross, ruined, used nipples you see in certain hentai. Nipples stretched and ruined from objects, after nipple sex, etc. You can generate it here.

The keywords I reccomend to get the effect are "disgusting breasts" and "gaping nipples".

Works uniquely with the keyword "lactation", but most generations will have some element of fluid by way of the training data.

This was a tricky one to train due to a lack of a source material, so be sure to post any exceptional generations so I can re-iterate the training with them!

Also, I'm experimenting with the "nipple plugs" tag, let me know what happens...
