A disturbing atmosphere gradually created in a house where a couple and their husband's father live together. Her father-in-law has always been lustful for the young wife'Tsukasa'who has a beautiful face and fascinating breasts. My husband's 10-day long-term business trip was decided at that time. Her unpleasant premonition, which she had always felt uncomfortable with her father-in-law's eyes and actions, was hit with a drug that strongly stimulated her sexual desire. The sensitive body feels pleasure so much that even the caress of his father-in-law, who hates it, can not resist, and the young wife has an abnormal ecstasy.
