His mother, wanting him to be successful like his father, always treats him strictly, forcing him to study constantly and forbidding him from going out or making friends until the university entrance exam is over. Kenichi is Yuta's best friend, the one who brings porn magazines and videos for Yuta to masturbate. They always have to secretly meet each other whenever Yuta's mother is away.

Seeing his huge penis and feeling overwhelmed by her uncontrollable sexual desires, she can no longer restrain herself!
