Ai, the daughter-in-law, is asked by her mother-in-law to see her grandchild’s face. One day, my mother-in-law suggested that I go on a trip to a hot spring. Although Ai was enthusiastic, she was ordered by her mother-in-law to make a child at a hot spring, and was even made to drink herbal tea, which is said to increase libido. On the day of the trip, Ai was so excited that she could not be satisfied with SEX with her husband due to the effect of herbal tea. On the other hand, the father-in-law is also energetic and tries to hold his mother-in-law, but he refuses. In the midst of each other’s agony, my father-in-law accidentally saw Ai’s nakedness and couldn’t stand it.
