This is trained on artwork by SneakAttack1221.

Along with the trigger sn34k1221 you might also want to try, breast bondage, Shibari, nipple bar, piercings, ball gag, improvised gag, and other assorted kink prompts.

Works best with anima-v1-turbo-aio

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