Former No.1 hostess who married a wealthy company president, the beautiful young wife Ran. In front of her husband, she acts pure and obedient, and plays the role of a kind older sister to her stepson. But the moment they're alone, she transforms. "Let me suck your little kid dick!" she says, sneaking behind her husband's back and indulging in her stepson's virgin cock as she pleases, revealing her true nature as a perverted tall slut. She trains her innocent, defenseless stepson into her very own masochistic pet.
