Lucy wipes her Erza/Juvia's butt

Just when Erza/Juvia got comfortable in her new diaper, Lucy went over to her and attempted to undo it. "What are you doing?" Erza/Juvia exclaimed. "I forgot something." Lucy answered. " you just had a mess in your panties. I need to clean your bottom before you put this thing on." She explained.

She undid the diaper and let it fall to the ground, forcing Erza/Juvia to cover her exposed self and blush. Lucy left the room and came back with a pack of baby wipes. Erza/Juvia blushed even more now. "Now sit still Juvia, and let me clean that messy, stinky bottom of yours." Lucy said sweetly, yet threateningly.

What was Erza/Juvia going to do?
