Water Closet: The Forbidden Chamber

You can choose one of five different female characters and play through, to see different scenarios from that character's point of view. Explore a cornucopia of forbidden themes as you assume the personalities of each of the characters and play through all parts of the interconnected story. It's a game that explores some of the more bizarre fetishes that can be found in an eroge.

Ikumi-chan just can't control her bladder. Julyne is a clumsy nurse. Reika's a model with constipation problems. Setsuko doesn't know how to use a tampon. Shoko has too much time for love of vegetables. Water Closet tells each of their stories in graphic, erotic detail, exploring themes that usually go unspoken.
