Erotic seductress Hikari hunts men through dating sites. She loves devouring young men's sperm and had been enjoying her single life, but her strict parents forced her into an arranged marriage, leaving her feeling reckless and desperate. With the wedding approaching, she still can't feel anything for her future husband and impulsively turns to dating sites to hook up with men. Today, she lures a new victim into a hotel. Her target is an older, middle-aged man—gentle, overly familiar, and at first glance, weak and unimpressive. However, this man is incredibly virile, with a keen sensitivity to nipples and ears—Hikari's weak spots. Once stimulated, she instantly transforms into a masochist, and this man immediately identifies her vulnerabilities, targeting them precisely until she's reduced to a quivering, breathless mess. Riding him cowgirl and taken hard from behind, she climaxes repeatedly in rapid succession. For the first time in ages, she feels utterly defeated, her chest tightening with emotion. Yet this extraordinarily potent man is destined to become a pivotal figure, bringing profound change to Hikari's life.
