This Model is for editing Weights of certain prompts like, plump, mature_woman, fat, belly, navel, small eyes, etc. Everything describing a Milf.

while there isn't much difference between original generation and using this lora. The stomach part of the one girl is made so that the belly is bulging out like a really fat woman, when using fat/plump. According to professional artist, Onna/Milf have Long Face and small eyes. have thicker arms and legs. Nipples are brown.

This is all the changes I've done using the Lora.

You can use prompts - large areolas, brown areolas, fat, plump, mole on face, big breast, veins on breast, lips etc.
