Yuki and his girlfriend plan to go to a concert together tonight. He planned to leave early but met Minami. She asked him to help complete the documents so that her boss could go on a business trip tomorrow. She alone didn't know when she would finish. Because the train was still 30 minutes away, Yuki agreed. But I didn't expect it to take so long that the concert had already started. So Minami invited Yuki out to eat something as a thank you. Because she was so busy drinking, Yuki forgot to pay attention to the time. By the time she remembered, the last train had already left. Minami immediately invited him to her house to spend the night. When she got home, Minami seemed a lot more comfortable, she wore a rather loose outfit and no underwear! Yuki can clearly see the most mysterious places on her body! And it seemed that this was intentional by Minami, she continuously made intimate moves with him that Yuki couldn't stand it anymore. The two continued to make love all night until the next morning. For the first time in his life, Yuki experienced new sexual positions and post-rape kisses that he had never done with his girlfriend...
