I was sick of having fingering motions that sucks.
So I hade one myself.
And it works like a tabasco on the pizza. the fingers actually fucking goes in and out in a good looking way.
weight 0.7-1.0 works well for me.
Slight chance to make "squirting" with a prompt but better use a mix of a lora that does that well.
Example of prompt :
"sensual_fingering,
The beautiful girl is fingering her vagina with her two middle fingers, her fingers are slowly sliding in and out of her vagina, water is squirting out of her vagina when her fingers slides out."
