After working as an international flight attendant for three years, Kanami, who married her beloved husband, was living a smooth life. One day, Kanami goes to a massage parlor introduced by a colleague on her day off. At that time when I was relaxing with a comfortable treatment using oil, the fingertips of the practitioner attacked from the crotch to the anus. Kanami, who is said to be a medical act and cannot resist, is pierced through the anus. Since then, Kanami, who is not satisfied with her husband's vaginal activities and has an anal pain, visits the massage shop again.
