Running it back with a fisting LoRA for Illustrious, seems to work okay with Noob as well. Have not tested but in theory should work for realistic models quite well.
Can be a bit finnicky sometimes, play with tags to get the right mix.
Main activation tags (should be self explanatory):
inpussy
inass (might need to add to negs sometimes if you want the above tag)
If inpussy is not giving the desired result, you can nudge it along with a few options, these are not necessarily trained:
female masturbation
fisting (a bit lackluster)
hand between legs
hand in panties
etc.
Other tags situational to change the position and other parameters, in general they all work well.
realistic - can try for realistic models or as a negative, the dataset contained a lot of real photos, but they have all been tagged appropriately and in my testing it did not bleed to anime models
clitoral hood,long labia; clitoris (a bit hit and miss this last one)
