[Shiosai (Ushio Kiyoshi)] Anta ni Kanojo nante 100-nen Hayai kara Uchi ga Wakaresasete Agetoita wa | You're 100 Years Too Early to be Getting a Girlfriend, so I Went Ahead and Broke Ya Two Up

A towering, big-breasted classmate in a school uniform and stockings corners the hapless sole male, her blunt teasing turning an awkward first encounter into a possessive, training-like relationship. Across the interior pages, her confidence and experience collide with his embarrassment and inexperience, while bold physical advances and provocative remarks establish a charged power imbalance. The mood swings from comic shock and humiliation to intense intimacy, framing a yandere heroine who has already decided he belongs to her.
