Juvia (in Natsu's body)

As Natsu/Juvia made his/her way to the unisex bathroom, he/she suddenly ran into Juvia/Natsu, with a very serious expression on her/his face.

Juvia/Natsu had pulled Natsu/Juvia inside the empty unisex bathroom and confronted him/her; blissfully unaware of the flood he/she was carrying in his/her bladder.

"What happened Salamander? We switched bodies!"Juvia/Natsu proclaimed.

"I don't know Juvia! I touched some weird coin and wound up like this. Can we please talk about this later?"Natsu/Juvia replied while still holding in his/her bladder.

"NO! I cannot be together with my handsome Gray in your body Salamander! Change us back!"Juvia/Natsu yelled angrily.

"I don't know how to. We should ask Levy or gramps for help, but right now, I GOTTA TAKE A LEAK! Natsu/Juvia exclaimed as he/she ran into the nearest stall.

Juvia/Natsu was mortified that Natsu would be relieving himself in her body and angrily slammed the stall door in an attempt to get Natsu/Juvia out.

"You CANNOT relieve yourself in my body Salamander! If you do, I will drown you in a sea of my embarrassed rage! The only man I would ever allow to do what you plan on doing is my beloved Gray!" Juvia/Natsu yelled angrily.

"I'm sorry Juvia, but your body really wants to pee. How long were you holding it in?" Natsu/Juvia asked as he/she was trying to remove his/her pantyhose.

"A few days. Every second without my gorgeous Gray is a stab in my heart, so I hold in my liquid waste for days until I can no longer bear it to stay by his side, even when he has to answer nature's call, I watch him through the sink." Juvia/Natsu lovingly replied.

"So what happens when you have to poop?"Natsu/Juvia asked.

"Don't be absurd Salamander. A rain woman never has to poop."Juvia/Natsu replied nonchalantly.

Just then the door opened to reveal...
