Ai, the daughter-in-law was asked by her mother-in-law to see her grandchild. One day, my mother-in-law suggested that I go on a hot spring trip. Although Ai was enthusiastic, she was still ordered by her mother-in-law to be a hot spring child, and was even forced to drink herbal tea, which was said to help increase libido. On the day of the trip, Ai was so excited that she could not satisfy her husband SEX due to the effects of the herbal tea. On the other hand, his father-in-law is also an energetic person, trying to hold on to his mother-in-law, but she refuses. While having sex, her father-in-law accidentally saw Ai naked and couldn't stand it.
