This LoRA reproduces decent hand over mouth scenes.

The model currently has some limitations:

There is only one pose
Portrait aspect ratio does not work well
The images seem to lack in brightness
The success rate is approx. 75% with fp16/fp8/Q8, drastically lower if < Q6

Prompting tips:

[Description of the woman covering the mouth] covering another woman's mouth with her hand. Her hand [description of the hand] covers the mouth of a woman [description of the second woman]. [Description of the environment and other details]

Example: A Middle Eastern woman with curly dark brown hair covering another woman's mouth with her hand. Her slender hand has painted red nails and gently covers the mouth of a shocked caucasian woman with blonde hair. They are in a cozy living room during the evening with a warm fireplace visible in the background through the room's windows.

It's working also with two men, woman on man or man on woman.

Observations: Weirdly enough, the Anime version of the LoRA can also produce very good realistic images, but it was trained only on anime pictures. However, the realistic version of the LoRA (trained only with real pics) struggles with anime style.
