Married for three years, on this occasion Ryo and her husband decided to go to a hot spring inn for a vacation. Ryo wanted to bathe and drink together with her husband, so they looked for an inn with mixed-gender bath. However, because her husband had a low alcohol tolerance, he couldn't handle it after a little drink and left Ryo alone in the bathtub. Oblivious to the time, the bathtub was taken over by other guests. Three lucky young men got to admire her beautiful body and even took photos. They used these photos to threaten Ryo and forced her to 'have fun' with them.
