I was annoyed that girls in my gens were only pointing fingers instead of shoving them in. Made with 86 1024x1024 Square closeup images with 90% of them being one girl sitting or laying on her back and another girl using one or more fingers. no faces in the training data so it plays well with face loras. i guess the captions were not optimal because the trigger word itself did not capture the concept as strongly as i'd hoped it would.

Training data only contains caucasian girls and little to no pubic hair so it might fight you if you want to create something diverse.

Use a structure close to this with about 1.3 lora strength:

two girls in the zxz pose, the shot captures the naked lower body of 20year old caucasian girl with firm perky breasts with long blonde hair. her legs are spread and pulled back and her vagina is on display. she is lying on her back. a 30year old brunette woman with very short hair can be seen sticking multiple fingers deep inside the pussy of the blonde girl.

If the scene becomes too detailed or the girls are too small in the scene the lora stops working so it should be kind of close range.
