"Wearing a high-cut swimsuit that accentuates her V-line, deliberately flaunting her sexy, slender legs to seduce us?" Fuua Kaede, the swimming club advisor, was once a trusted figure among her students. But one day, she's suddenly betrayed. Having strived to meet the expectations placed upon her, she becomes a target—her most intimate desires exploited, drowning in pleasure until she loses herself completely. Forced into a swimsuit, drenched and degraded as a lustful teacher, she's betrayed, gang-raped, and turned into a living sex toy.
