Ririko is a neglected housewife, who one day walks in to her son room without knocking, interrupting his fapping session.
The most crazy thing about it, is that Yudzuru was moaning her Mom’s name while masturbating... and they are both mortified about it.
That same night, they have “the talk.” And things continue to spiral into craziness as Yudzuru confesses his crush on his mom.
Ririko should have stopped him right there, but years of neglect made her feel a strange sense of flattery. And she proceeds to spoil her son Yudzuru.
After the can is open, Yudzuru is unstoppable, and with his youthful stamina he overwhelms Mommy Ririko’s reasoning.
