Lucy inspects Juvia/Erza's panties

"Don't worry about it Juvia. I'm used to being in a stinky apartment. Thanks to Erza over here." She points to Erza/Juvia. They both blushed. "But we ought to check your undies! We wouldn't want to to be running with an accident in you panties, would we?" She said.

She walked up to Juvia/Erza and lifted up her skirt, the stench getting worse. "PU! I guess I have proof that both of you have stinky butts!" Lucy laughed. The other two girls blushed again.

Lucy grabbed the waistband of Erza's white panties and pulled them back to look inside. What does she see?
