Suzu's husband was invited by his seniors to go to the hot springs. Everyone brought their wives with them, so he invited Suzu to go with them. But when they arrived at the bus station, everyone made excuses that their wives couldn't go, so Suzu was the only woman left. Suzu's husband was always 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 springs would help him improve somewhat, and they would take advantage of this opportunity to have a child together. Before going to the hot springs, everyone gathered to drink together. Because he couldn't drink, Suzu's husband quickly got drunk and fell asleep, leaving only Suzu to serve her husband's three colleagues. After drinking, Suzu went to take a bath. Unfortunately for her, one of them changed the nameplate of the shared bathroom to a private bathroom, so she entered the wrong room. While she was taking a bath, the three of them came and took a bath with her. She wanted to leave, but they said they would promote her husband if she agreed to serve them. Because of her husband, she agreed. But the feelings of pleasure and joy they brought were things that her impotent husband could not give her. They continuously did all kinds of positions with her, said lewd words to her and she completely accepted and responded to them, she even let them ejaculate directly inside her.
