Targeted by a school swimsuit maniac, Aika Yumeno is cornered by a perverted man obsessed with her in a swimsuit. By the poolside, she is forcefully taken and filmed against her will. Using the video as blackmail, he repeatedly assaults her while she remains in her swimsuit. The more she resists, the more aroused this deranged stalker becomes. "Your body looks perfect in that school swimsuit. I'm going to fuck you raw again today, but I want to savor it longer, so I won't cum inside just yet." Her swimsuit-clad figure drives him further into madness.
