Suzu's husband was invited by his senior colleague at work to go to a hot spring, where everyone brought their wives along. So, he also invited Suzu to go with him. However, when they arrived at the bus station, everyone made excuses that their wives couldn't make it, leaving Suzu as the only woman. Suzu's husband always felt insecure about his sexual abilities, so he didn't have sex with her much even though she really wanted to. He hoped that the hot spring would help improve things, and maybe they could have a child together on this trip. Before going to the hot spring, everyone gathered to drink alcohol together. Since Suzu's husband couldn't handle alcohol, he quickly got drunk and fell asleep, leaving Suzu alone with three of his male colleagues. After drinking, Suzu went to take a bath. Unfortunately, one of them changed the sign of the communal bath to a private one, and Suzu mistakenly entered. While she was bathing, all three men entered and bathed with her. She wanted to leave, but they said they would promote her husband if she complied with serving them. Out of concern for her husband, she agreed. However, the pleasure and satisfaction they provided were something that her sexually weak husband couldn't give her. They continuously engaged in various sexual positions with her, spoke obscenities to her, and she completely accepted and responded to them, even allowing them to ejaculate inside her!
