The son-in-law, perhaps having drunk alcohol, hugged Tsubaki. Tsubaki feels lonely but gradually accepts it... One night, her son-in-law sneaks into Marika's bedroom.

Even though Natsuko knows it's no good, she thinks it will save her from feeling lonely... In the past, only the missionary position was allowed for married couples. Aya, who only knew that, was shocked by the activities of her daughter and her husband...
