Today, Takeshi attended a university class reunion. There, he met Yuko, his ex-girlfriend whom he hadn't seen in five years. Yuko was still as beautiful as before, and she had recently gotten married. Everyone suggested going for a second round, but both Yuko and Takeshi declined. They continued to drink and chat, when suddenly Takeshi remembered he had missed the last train. Taking a taxi home would be too expensive, and while he was unsure of what to do, Yuko invited him to spend the night at her place, as her husband was also not home that day. Yuko and her husband still lived in the same room as before, a room that Takeshi was very familiar with. When they got back, Yuko immediately put on a thin, loose shirt that revealed her beautifully rounded breasts without any bra underneath! Unable to resist the beauty of his old girlfriend, Takeshi embraced her. Yuko made no attempt to stop him; instead, she joyfully enjoyed the moment with him. It turned out that even though she had a husband, he was always busy with work and showed no concern for her. When meeting Takeshi again, past memories flooded back, and she wanted to ignore everything, to immerse herself in sexual pleasure just like before...
