I know this is a doujin manga, but there are a lot of official scenes of Misae, and other girls in the Shin-chan universe, using the bathroom, and not discretely at all. Not sure about /s/cenes in the official manga, I definitely recall a lot of scenes in the anime. One scene in particular featured Misae begging Shin to let her use the bathroom, then she proceeds to actually crap her pants (on screen), because Shin was hogging the toilet. There's hundreds of episodes of Shin-chan that never see the light of day on American piracy websites, but hopefully one day the RAWs will get uploaded, because if there's one thing Shin-chan does right, it's potty humor.
