Kanojo ga Separate o Matou Riyuu

A virile girl named Amane Kojou struggles with her unassuming boyfriend's timid advances, often finding herself yearning for something more. She pours her pent-up passions into her track and field endeavors, but the growing frustration mounts as her intense desires remain unfulfilled. To compound matters, a lewd middle-aged man can't help but leer at her risqué athletic attire with insatiable curiosity. In the privacy of her apartment, Amane frequently indulges in self-gratification after-hours. Unbeknownst to her, this lecherous landlord stealthily records these intimate acts! Intriguingly, he proposes a trade: the deletion of his incriminating footage for a one-sided liaison on his part. Although repugnant, Amane's famished body begins craving the man's touch more and more... What will become of Amane?!
