Essentially primarily two usecases (as I had trouble getting that with lightning loras, which works with this):
T2V turning other e.g. blowjob lora into deep deepthroat
I2V same.
T2v generation itself is a bit lacking regarding anatomy and being pretty closeup.
Also it allows atleast sometimes controlling the direction, while typically blowjob etc. loras always force that motion upon you.
Strengths roughly:
High/Low each 0.5-1
I2V seemed to do fine at 0.8/0.8 or 1/1
PROMPT pieces:
taking a mans erect penis deep into her mouth
taking a mans erect penis out of her mouth (and backing away from it)
