Her daughter-in-law Sumire was under pressure from her mother-in-law to give her grandchildren. One day, the whole family decided to go on a hot spring trip. However, his mother-in-law ordered him to abstain from sex for a month before the trip to give birth. On the day of the trip, Sumire was unhappy with mechanical SEX with her indifferent husband. On the other hand, his father-in-law also tried to hold on to his wife but he refused. Two people with too much sexual desire went to a hot spring to soothe their bodies. And the father-in-law happened to witness Sumire taking a bath.
