Otoko ga Uke - Kitsune-chan X Tanuki-kun

Femdom hentai romance doujin.
(side note: it contains urination too.)

A fox girl and her fiancé, a raccoon dog (tanuki) boy, are left alone together after their respective families leave somewhere. They are very nervous in one another's presence, but then something happens and they get locked in a storage closet! In a small confined space, their bodies are in close proximity and the raccoon dog boy becomes flustered!

(She's so close... and smells really good...)
This is not the time to be thinking like that!!!

"I'm sorry! It's scary, isn't it!"
"Don't worry, it'll be okay."
But something's wrong with the fox girl's demeanor......?

"I'm not scared... it's something else."
"Huh?"

"I need to pee... and can't hold it any... longer..."
Peeing herself, something snaps inside the fox girl and she turns her horny gaze to her fiancé...
What ever will the raccoon dog boy do...!?
