Shota is left in the care of his friend 'Nanako' due to his mother's sudden emergency. Seizing the opportunity, he takes full advantage of his stepson privileges—using cleaning tools to prank her, groping her breasts, sneaking upskirts, and even mastering the technique of bringing Nanako to climax with a broom. While watching TV, overwhelming urges drive him to suck her tits, indulging freely in her big breasts using his privileged status. After dreaming about Nanako deflowering him, Shota becomes aroused and sneaks into her futon. The second installment of Shota's POV adventures features Mori Nanako, packed with reverse stepson perspectives and one thrilling development after another.
