結婚生活を送る鈴の元に届いたメールに添付されていたのは、元彼に撮られた過去の露出プレイ写真。セックスレスに悩んでいた鈴は、当時の興奮を呼び覚まされ元彼と密会を繰り返すように。バレてしまうかもしれないスリルが鈴の変態性癖を刺激し、エスカレートする野外SEX。貞淑だった妻の姿はもう、そこにはなかった。

Suzu, a married woman, receives an email with attached photos of her ex-boyfriend engaging in exhibitionist acts from the past. Troubled by her sexless marriage, Suzu's past excitement is rekindled, and she begins secretly meeting with her ex-boyfriend again. The thrill of potentially being caught stimulates Suzu's perverse tendencies, and their outdoor sex acts escalate. The image of the once virtuous wife is nowhere to be seen.
