I couldn't find a similar lora for this position except the "sword swallowing position" but that didn't have the effect I was looking for.

Trained on 170~ images, generated captions with each edited by hand. Works best, in my opinion, at 0.6-0.8 weight for getting the position, but it also carries some lighting effects that I really like at the lower 0.2-0.4 weights.

V2:

Trained on 125~ images, generated captions with each edited by hand. Works best, in my opinion, at 0.6-0.8 weight for getting the position, but it also carries some lighting effects that I really like at the lower 0.2-0.4 weights.

Removed all images from training set that were not under boy, facing girl. Replaced those with the trigger word "blowjob from below"

I took the model down because I was seeing some major flaws in the generations after even more testing. I think that because the face is always obscured by the penis in this position, SD has a hard time keeping the facial structure correct. The refined training selection seems to have helped in that the face will mostly be symmetrical on each side.

I had more success when I used the good generations as canny edge maps and then applied those maps for future generations with controlnet.

Attempted to differentiate positional arrangements with the following trigger words:

"under girl, facing boy" : viewer is under the boy, girl is facing viewer (images tagged this way, but I could not get it to work with my checkpoints based on women as the main focus, so your results may vary)

"under boy, facing girl": viewer is under the girl, boy is facing viewer

"behind guy, laying on her back": viewer is behind the boy, girl is laying underneath. May work better with "69" as additional trigger.

Blowjob depth trained with following variations:

"just the tip" : mouth at the tip of the penis or just around the head/glans

"blowjob" : tip inserted fully in mouth

"deepthroat" : halfway+ penis in mouth

"to the hilt" : entirely swallowed/all the way to the base

I got varying results and the weights may need adjustment.

Additional positioning trained through the following:

"hand on another's head" : one hand on girl's head

"hands on another's head, grabbing head" : both hands on girl's head (interchangeable)

"close-up" : close up shot with face and penis

Detail adjustment:

"lips around penis" : if lips were pronounced in initial image

"dark-skinned male, dark-skinned penis, interracial" : typical traits to adjust male skin color
