"I have a wedgie"

"I have a serious wedgie. These panties are really riding up!" Juvia/Erza says shamefully. She was blushing deep red.

The other two slightly giggle. "Well no wonder! No pair of panties would fit around Erza's beautiful butt!" Lucy thought scandalously. Erza/Juvia looks over to her blonde friend with concern.

"Lucy are you alright? Your face is red." She asked. Lucy quickly snapped out of her fantasy and regained her composure. "No! I'm fine!" They dropped the subject and returned to Juvia/Erza.

"So how bad is your wedgie Juvia?" Lucy asked. Juvia/Erza blushed. "Pretty bad. Look." She lifted up her skirt and showed her the massive wedge she was sporting. The white undies were halfway up her butt, exposing Erza, beautiful white butt cheeks.
