A salaryman husband was in a traffic accident six months ago and became paralyzed, living in a wheelchair. Although doctors gave up on a full recovery, he couldn't accept it and visited various orthopedic clinics and osteopathic offices. One day, a mysterious medical practitioner claiming to be a "wave osteopath" came to the house, perhaps requested by the husband. After receiving this suspicious treatment, the husband somehow believed he would be cured and became devoted to the man. The man then began to parasitize the family. The brainwashed mother and daughter eventually reached the point where they provided sexual service as told by the man... "This catch is the best, I'll take my time fucking them." The mother is fucked and reaches climax in front of her daughter, while the daughter devours the cock while being watched by her mother. With their minds completely eroded, the mother and daughter turn into the fraudster's human onaholes!!!
