URL and description from source: https://civitai.com/models/728360/anal-gape-from-behind Put together this dataset for a Flix lora. Decided to try it on SDXL first to save some $. Works pretty well if properly prompted. I recommend AlbedoBase checkpoint.

Note: the trigger phrase from the source is "a woman showing her gaping anus from behind". It would not fit in the trigger words section when adding this model.
