With base model I used: sdxxxl_v30.safetensors (probably won't work with other base models, feel free to try and let me know)
This finger_ass is a Lora, I got good results with weight 0.7 0.8, haven't tried yet for more, feel free to try and post results.
This Lora has been trained with 768,768 resolution
To trigger that pose you can type just those:
1girl, solo, finger ass, **** fingering, ****
you can choose where the model can stay:
lying on bed
lying on sofa
lying on floor
Those three can have additional tag: on side
You can have another two poses (not working well as the others laying but might get some good results) which is:
standing doggystyle
kneeling on chair
Some pictures of the training had stuffs like:
High heels, panties, lingerie, dress, shirt, skirt, underwear, socks, woman underwear, {color} nails polish, hand on own ass
those last tags are experimental and can't guarantee good results, feel free to post pictures with the prompt if you get good ones
