This is the Illustrious LoRA that can add a thick knotted cleave gag to a person. The gag can be used with a color (add another tag 'color gag') or with a pattern ('patterned gag' and then try to define a pattern).
The model has some knowledge of bondage, especially ropes around the torso (try shibari, bound breasts, bound ankles, bound wrists etc). But the main goal of the model is the gag, so I suggest using another LoRA (at least until we test it more).
