Today Takeshi attended a university class reunion. There he met Yuko, his ex-girlfriend whom he hadn't seen in 5 years. Yuko still looked as beautiful as she did before, and she had recently gotten married. Everyone invited each other to go drinking, but both Yuko and Takeshi declined. They continued to chat while drinking, when suddenly Takeshi remembered that he had missed the last train. Taking a taxi home would be too expensive, and just as he didn't know what to do, Yuko invited him to stay overnight at her place, since her husband was also not home today. Yuko and her husband still lived in the same room as before, a room that Takeshi was very familiar with. When they arrived, Yuko put on a thin, loose shirt, revealing her large, round, and beautiful breasts without wearing a bra underneath! Unable to resist the beauty of his ex-girlfriend, Takeshi hugged her. Yuko did not resist and even enjoyed it with him. It turns out that despite being married, her husband was always busy with work and never cared about her. When she met Takeshi again, memories from the past flooded back, and she wanted to ignore everything, to indulge in the sexual pleasure just like they used to...
