That JAV

Shion moves into a women-only apartment and goes to greet her neighbors Yui and Hibiki. They are a lesbian couple, but both of them are interested in Shion, and both of them press Shion to have relations with them without telling each other. When they find out that Shion is a transsexual, each of them asks for a relationship with the other if they don't want it to be revealed to the world.
