Rio, who lives a peaceful married life, decided to go to the obstetrics and gynecology department for a checkup for the future. After the examination, the doctor in charge, Usami, handed her a painkiller. The painkiller's side effect was that it made her drowsy... Seeing Rio in a deep sleep, like a doll, Usami smiled fearlessly and devoured her lips and sucked her breasts... After enjoying the taste of her pussy, he thrust his cock deep inside her and poured milky juice into her. When Rio woke up, she felt something strange, but she didn't understand what it was. However, her body remembered the truth of what felt good.
