An ngây thơ female college student has just moved to Tokyo from Fukuoka. She moves into a cheap shared house with a rent of 30,000 yen, but all of her roommates are horny men. They take advantage of her innocence and devour her cơ thể every day, playing with her delicate cơ thể and nhạy cảm nipples. She loses the will to resist and becomes addicted to khoái cảm in this house-confined shared life.
