Forgot the name to a manga about urinating inside a girl.

It was with a foreigner princess and urinating inside means your engaged. It's not pee drinking alice. The guy was heaver then that MC. Chubby face no glasses. Im not sure if it all one tankobon but i think it had at least 3 to 4 chapters

:^)

I know there's that Meme50 shota chapter where the kid pees inside his art teacher.

Nah. MC was in highschool.

Sounds like most public schools in America.

??? Im sure this happens more in germay then Puritan county usa.
