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. It seems that the painkiller has a side effect of making her drowsy... Seeing Rio, who had fallen into a deep sleep and become 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 in his milky juice. 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.
