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 very enthusiastic, her mother-in-law still ordered her to act like a child in the hot spring, and even forced her to drink herbal tea, which was said to increase sexual desire. On the day of the trip, Ai was so excited that she could not satisfy her husband with SEX due to the effects of the herbal tea. On the other hand, her father-in-law was also an energetic person, trying to hold on to his mother-in-law but she refused. While having sex, the father-in-law accidentally saw Ai naked and could not bear it.
