Episode :
Naoto is an ordinary individual who, after the death of his mother and his father’s remarriage, finds himself with two wonderful women in his life—Sachiko, his stepmother, and Yui, his stepsister. As time goes by, Naoto begins to worry about Yui’s emotional distance from him.
One day, he checks his phone and stumbles upon an incredible app that promises to assist its user in understanding the person they choose. Eager to gain deeper insight into Yui, he promptly tests the app on her and unexpectedly gains control over her body!
Utterly bewildered, Naoto reenters Yui’s room and catches sight of her reflection in a full-length mirror. Unable to suppress his desires any longer, feelings of lust for his sister’s body overwhelm him. Consumed by his powerful sexual urges, Naoto touches Yui’s sensitive breasts and firm nipples, indulging in the pleasures of an inexperienced partner.
