Ijiwaru Senpai to Ookina Kouhai ni Hasamare Douji Zeme!?: Ue mo Shita mo Issho ni Ijirare Torotoro ni

Kojika is an ordinary office worker with zero real-world romantic experience, but she harbors a deeply private hobby: writing and publishing self-insert fantasy fiction online. Her stories center on passionate three-way encounters featuring thinly veiled versions of her company's two most popular men—Kosaka-senpai, the top-performing salesman, and Inukai-kun, a genuinely kind and well-liked junior colleague. Because all three attended the same university, Kojika eventually finds herself joining them for drinks one evening after work. As the alcohol flows and their conversation turns unexpectedly candid, Kosaka-senpai suddenly confronts her with a devastating question, asking if a specific online account belongs to her. In an instant, her closely guarded secret is shattered—the two men now know she has been authoring explicit fantasies starring them. What follows is a startling encounter that mirrors the very scenarios she had only ever dared to imagine on the page. Despite knowing she should refuse, Kojika finds herself entirely unable to resist their advances, drawn into a compromising situation where both men are determined to bring her fictional desires to life.
