The Gluteal Wave (or "Walking Butt Crease")

Description:

Model trained on 45 images of various models and characters, focused solely on the "wave" the gluteal folds of a curvy butt make when the body twists, either while walking or twisting your torso.

Only tested on Plant Milk (Coconut) by Ocean3, but probably works fine on other Illustrious-based models.

Prompting suggestions:

Required trigger: asswave

Positive suggestions: twisted torso, ass focus, looking back, thighs
