This lora is designed to produce a vaginal knotting effect. It's a bit hit or miss because krea2 doesn't know a lot of furry/anthro concepts.

There's two versions: One for vaginal knotting, and one for general knotted penis.

It does really well at cowgirl, straddling, and spooning, and doggy-style. When the woman is facing away it sometimes will generate a clitoris in the wrong place. That can usually be fixed by adding the "Grippypussy" lora at a low weight (0.4-0.5)

the vaginal knotting model can do non knotting poses too, but is strongly biased towards knotting, so I suggest using the other model.

Dataset was composed entirely of furry art images, focusing on human female/anthro male images with a mix of 3D renders and cartoon/illustration to try and prevent a big style bias.

I've only tested this on moody krea mix v4 since that has given me the best generation results. I can't predict how it will work with other checkpoints.

Prompting guide:

If you want knotting, describe the characters, pose/position, and use the words knot or knotting. Don't use "penis". For example:

her wet pussy is being stretched by the werewolf's huge pink veiny knot

If you don't want knotting: Describe the penis entirely. For example:

The penis is thick pink and veiny with a pointed tip and huge prominent knot at the base
