An unsettling atmosphere gradually arose in the house where the couple and her husband's father live. My father-in-law has been lustful for his young wife 'Tsukasa' with a beautiful face and fascinating breasts. At that time, my husband's 10-day long-term business trip was decided. Tsukasa's bad premonition, which had always felt uncomfortable with his father-in-law's eyes and actions, was correct, and he was given a drug that strongly stimulated his sexual desire. The sensitive body feels so much pleasure that even the caress of my father-in-law, who hates it, cannot resist, and the young wife is in abnormal ecstasy.
