Yes

Ellie began to circle around May. Lurking for a possibility to further shame her. Then she lifted the bottom of her blouse, then she grabbed the waistband of her underpants. "May, why are you so nice to tease. Be nice and put your hands above your head!"

Knowing she'd better cooperate, May put her hands over her head, hesitantly. Because of this, her blouse naturally crept up so that her entire underpants were visible to everyone. Ellie used this moment to grab her waistband and pull it up really hard, way between her buttocks that became more and more visible. The wedgie was a complete surprise to May, she never imagined and expected to be in school with her butt bare. She let her hands slide off her head to relieve the pain, but Ellie pulled even harder and May lost her balance. She fell forward on her hands and knees.

The hem of her blouse folded over her back so that her entire ass was exposed. With only a thin thread of fabric to protect her most private parts. Tears in her eyes from the pain and shame.
