In a seedy, run-down apartment, the walls echo with the moans of animated women. A group of horny housewives, known as hitozuma, have taken over the space, their lustful desires spilling out into the shared hallway. Each room is a canvas of carnal pleasure, with women of every shape and size pleasuring themselves and each other. The air is thick with the scent of sex, the sound of wet pussies being fingered, and the sight of thick, veiny cocks being sucked. The apartment becomes a symphony of sin, a visual novel come to life.
