Morita is Kintaro's junior, and the two also went to the same school, so they are very close. Therefore, Kintaro often takes him to his house for dinner and drinks. But Kintaro didn't expect that Morita was fascinated by the body of his wife, Natsu. Today, because he was too drunk, Kintaro fell asleep at any time. Taking this opportunity, Morita immediately squeezed the big breasts he had been waiting for for a long time, confessing his feelings to Natsu. Natsu repeatedly refuses, but her superficial actions show the exact opposite. Morita easily groped all over Morita's body, put his hand in her pussy, and kissed her. When Kintaro returned to his bedroom, there were only two people left. They no longer have any restraints, they both take off all their clothes, ready for intense sex even though Natsu's husband is in the next room. And since then, the two have been constantly fucking each other every time they get the chance. Although he knew that if this was discovered, Natsu's current happy life would end, Morita's career would also be in danger. No need for love or affection, what both want is just the intense pleasure of sex...
