Does she pinch the fabric of her underwear between two fingers in the front and back then with a flick of wrist wedge them into her slit or something? They are tightly UP there by the look of it..

Try these steps:
1: Ensure you have underwear on. Not briefs, underwear. And it needs to be slightly baggy. 2: Sit on any hard, flat surface. 3: Now, slide to either left or right direction without lifting your ass from the surface. If you did this right, your underwear should shift a bit. 4: Again, without lifting your ass, slide to the opposite direction you just did.
Congrats, now you have underwear sandwiched between your buttcheeks.
So simple answer to your question: it likely happened after she's sitting.
