結婚して数年。夫婦生活が上手くいってないわけでもない。それなのにどこか毎日が物足りない。平凡すぎる日々に刺激を求めて莉央はシースルーの洋服を身にまとった。乳首も胸もアソコでさえも、大事なトコロが全て透けて見えてしまう快感にハマっていく莉央。いつものようにスケスケ衣装に着替えた莉央は卑猥すぎる姿を隣人に見られてしまう。戸惑う隣人を家に誘いこみ、艶めかしく透けるボディラインを見せつけ誘惑していく。

It's been several years since she got married. Their married life isn't exactly bad. Yet, somehow, every day feels unfulfilling. Seeking excitement in her overly ordinary life, Rio puts on see-through clothes. Rio becomes addicted to the pleasure of having all her important parts—her nipples, breasts, and even her private parts—visible through her clothes. As usual, Rio changes into her see-through outfit and her neighbor sees her in a way that is too lewd. She invites the bewildered neighbor into her house and seduces him by showing off her alluring, see-through body lines.
