Yusuke and Ryo have been happily married and living together for three years. They thought their happy life would last forever until... One day while drinking with his business partner, Asano-san, who is an editor of a publishing company and also an important partner of Yusuke, saw pictures of Ryo. Instantly, Asano thought to himself, "she is the one!" She would be an incredibly famous lingerie model! Unable to refuse such a big partner, Yusuke had no choice but to persuade Ryo. Out of love for her husband, she agreed to go and see if it suited her, and if it didn't, she would decline immediately. But when they got there, Asano kept persuading her to participate in a test photoshoot, assuring her that the photos taken would not be published. Because Asano and everyone else were so enthusiastic, she also agreed. This was also the first time she got to wear incredibly alluring lingerie that accentuated her deadly attractive figure; she herself was surprised at how beautiful she looked. And when taking pictures, wearing the right underwear, creating seductive poses in front of men and her husband made her extremely embarrassed and unable to concentrate. Her husband saw this and went out to make her less embarrassed, and Asano was the only one left in the room. The more embarrassed he was, the more angry Ryo felt. Asano also discovers that her panties are soaking wet and learns of her lewd self. So he took the initiative to groping all over her body and fucking her right in the room. Although she knew it wasn't right, the pleasure of being fucked right up close to her husband, as well as Asano's skillful skills, made Ryo gradually fall into the abyss of sensuality. She gradually no longer wants to be close to her husband, but only wants to be fucked by Asano and even photographer Yuta, satisfying her sexual desire...
