My adult girlfriend Momono was raised by strict parents and has to be home by 5 PM. Our dates never go beyond stylish cafés and museums because her father always calls to hurry her home. One day, Momono invites me over and I meet her mother, Yurika, a beautiful woman with irresistible mature sex appeal. When Yurika tells me to break up with her daughter, I lose control and push her down. That begins our secret affair, meeting for creampie sex as soon as Momono leaves to make her curfew.
