After weeks of pleading and coaxing his girlfriend Yui into finally allowing him to sleep with her next week—a highly anticipated event for Shinya—he bursts into her home ready for action! Finding Yui deeply asleep and unable to wait any longer himself to resist the urge for intimacy immediately upon entry. However! As he drives deep inside her body in a passionate thrusting rhythm that quickly escalates his desire to climax right there on the spot. It’s only when he gets a clear look at the beautiful face beneath him that Shinya realizes his mistake: this isn't Yui after all! As Yui returns home shortly after discovering what is happening inside her house, Shinya is confronted with the stunning reality: he has mistakenly taken his future mother-in-law, Rio Ohara! Rio had stopped by unannounced to visit her daughter and was caught completely off guard as Shinya claimed her. Far from being angered by this unexpected encounter, she feels an immediate surge of thrilling excitement and pleasure. Due to ongoing marital discord with her husband, Rio has been starved of satisfying sexual relief for quite some time. Shinya proves to be an incredibly potent partner; his large, healthy physique and robust stamina push Rio over multiple peaks that her husband simply couldn't deliver before. From that moment forward, Rio begins leveraging this delicious accident, constantly demanding that Shinya satisfy her needs. And Shinya? He finds himself utterly incapable of resisting the curves and seductive presence of the woman who will become his wife—the gorgeous future mother-in-law!
