This is trained on artwork by Lerra22.

The example images have been generated as per the prompts and then run through a Hires Fix.

This was created using natural language prompts, so along with the trigger L3rra22 you might also want to try descriptions containing, latex, rope/metal bondage, nipple piercing, ballgag, harness gag, mask and other assorted kink prompts.

Seems to work quite nicely at CFG Scale strength 3.5 and around 20 Steps, using Euler a Simple.

But please experiment as I have not done an exhaustive test of all of them.
