Too many buttjob loras that are more like butt-rests because the dick barely even touches the cheeks. This is meant to ensure its DEEP between them. And also to be capable of a few more angles.

Trigger tag is: Engulfing Buttjob

Also try things like side view or side angle for other poses.

I recommend putting 'monochrome' and 'grayscale' in your negative prompt. Seems to result in less weird colorations.

Probably needs extensive testing, been awhile since I've trained one. If it's a total mess I'll take it down but sadly I've got no way to pre-test it outside Civit.
