Water Closet: The Forbidden Chamber: Remastered: Deluxe Edition v1.0 by Guilty Win/Mac/Linux - Adult Sex Game

Play as five women on five different routes, all joined by one common factor; they got potty problems.

Ikumi just can't stop peeing when she gets nervous.
Julyne is a klutzy nurse working in a urology clinic.
Reika's a model who just can't seem to shit.
Setsuko is still figuring out how tampons work. She's not as young as that makes her sound, just an extraordinarily late bloomer.
"Shoko has too much time and a love of vegetables" is what we wrote about her the first time around.
