Kanojo ga Separate o Matou Riyuu

Amane Kojou, an innocent young virgin, grows increasingly frustrated with her overly polite boyfriend who limits their physical intimacy to mere kisses. To channel her built-up energy, she throws herself into her track and field club activities. However, the high physical drive natural to an athlete only intensifies her inner frustration—all while a creepy middle-aged man keeps his eyes glued to her revealing two-piece athletic uniform.

Living alone in her apartment, Amane frequently resorts to late-night self-pleasure, completely unaware that her middle-aged landlord is secretly recording her every move! Demanding physical favors in exchange for deleting the illicit footage, he forces her into a one-sided, coerced relationship. Despite her moral resistance, Amane’s long-neglected, highly sensitive body finds itself craving the older man’s touch more and more with each encounter… Where will Amane’s fate ultimately lead her?!
