This LoRA trained on differents positions with the tail of the penetrated one around the partner. I hope this one will work on your prompt, it may be a bit unstable.

The Illustrious LoRA is way more stable than the previous Pony one, it should be way easier to generate any tail type for multiples creature type (don't forget to specify the reptile/cat/plant etc... texture of the tail)

The keyword is 'tail wrap around body, tail around' but you can use character like :
- 'monster girl' for humanoid characters
- 'anthro girl' or 'furry girl' for animal characters

Some arguments may exist but trigger nothing...

For the Strength of this LoRA, it seem to work best on 0.8 for pony, but you can keep 1 on illustrious variant.
