Morita is a junior to Kintaro, both of whom attended the same school and are very close. That's why Kintaro often takes him home for dinner and drinks. However, Kintaro never expected that Morita would be infatuated with his wife, Natsu. Today, due to being too drunk, Kintaro passed out without realizing it. Taking advantage of this opportunity, Morita immediately grabbed the large breasts he had longed for and confessed his feelings to Natsu. Despite Natsu's continuous rejection, her actions showed the opposite. Morita easily touched all over Natsu's body, put his hand into her vagina, and kissed her. When Kintaro went to the bedroom, only the two of them were left here. They no longer held back, both stripped naked, ready for a passionate sexual encounter even though Natsu's husband was right next door. And from then on, they continuously had sex whenever they had the chance. Although they knew that if this affair was discovered, Natsu's current happy life would end, and Morita's career would be in danger. They didn't need love or emotions, all they wanted was the intense pleasure of sex...
