[Hiiro no Kenkyuushitsu (Hitoi)] Ochiba Nikki Another Page 4

A nervous boy pops a mystery disc into his computer and clicks through video files that stop him cold—grainy footage of a girl he might know, collared, leashed, and blindfolded while an older man trains her for his own use. She squirms in a school swimsuit one minute and kneels dripping in a public restroom the next, conditioned to thank him after every time she's been used while the camera keeps rolling and her secret viewer recognizes the netorare horror unfolding on screen. When her master dangles the promise of their next 'lesson' at his home, her leash—and everything the boy thought he knew about her—ends up firmly in someone else's hands.
