JUQ-164 The daughter-in-law had an affair with her father-in-law and became pregnant due to the pressure to have children from her mother-in-law.

The daughter-in-law Sumire is under pressure from her mother-in-law to have a child for her. One day, the whole family decides to go on a trip to a hot spring. However, the mother-in-law orders her son to abstain from sexual relations for a month before the trip to conceive. On the day of the trip, Sumire is dissatisfied with the mechanical sex with her indifferent husband. On the other hand, the father-in-law tries to hold onto his wife, but she refuses. The two individuals, filled with sexual desire, go to the hot spring to soothe their bodies. And the father-in-law happens to witness Sumire bathing.
