I was having a hard time getting this particular concept through prompting alone, so thought I'd have a go at training a LORA on it. It seems to work pretty well.

The concept I was going for is for the groin area to be visible, barely covered by the bottomwear which is pulled down slightly. If panties are visible, they should be pulled down around the same height, and not draw too much focus.

The main trigger word is groin.

Other useful tags to use (positive or negative as required):

pants pull, shorts pull, pulled by self, panties, no panties, female pubic hair, pubic hair peek, ?????, ????? peek
