Naruto

Sakura stared at Naruto, stark naked with her mouth hanging open, and Naruto stared back, wearing nothing but a towel around his waist, equally surprised.

Had that little pervert jumped over the privacy fence? No, she realized. There was no privacy fence because it was mixed bathing day. The hot springs had those about once a month, and if Sakura knew what day it was, she would have waited till next week.

At this point, Sakura had two choices. First, she could panic. She could hide behind Hinata, steal her towel and wrap it around herself, or just run back into the locker room and try to forget that her annoying blond teammate had just seen her full frontal assault.

Or, she could play it cool and pretend that nothing unusual was going on. "What, didn't you know it was mixed bathing day?" she could say. "I thought everyone knew." That would be a much greater sacrifice than what she had planned, but it could get the job done of getting Hinata to open up.
