Make her wear diapers, of course.
I like where this is going
They did censor it in the US/German version, they just took the scene out. This is the real scene. There's another wetting scene somewhere that they took out in the censored versions. Fucking çucks.
My childhood drama consists of not being able to piss in a lot of situations so whenever I dream of toilets, I get dangerously close to wetting the bed.
In other words OP, I would just piss in my bed and show her that it's all good.
blame it on Chibiusa. because i know it's her fault.
