Overview

Hinano is my wife's stepchild. She has been raising him with care as if it were her own child, but today she finally brought him to her house. Well, have you reached that age already? I'm a little lonely, but as long as Hinano is happy, I'm fine with it. As a father, would he do anything that would interfere with their love journey? ...That's what I thought, but when I handed Hinano a bath towel in her changing room, I suddenly felt a dark emotion. I have to protect Hinano before her virginity is taken away by a young man who doesn't even know what horse's bone it is...!
