In order to help the daughter, who has graduated from high school and is becoming an adult, acquire correct sexual knowledge, we had her take on a naughty mission called "sex education for becoming an adult"! In a special studio where the mother cannot see inside the room, the father and daughter touch each other's bodies and quickly become closer in both body and Kokoro! Although they know it's wrong, the father and daughter can't stop getting turned on and have raw creampie sex!
