Aono Miku, a beautiful high school girl and member of her school's dance club, is known for her long black hair, slender flexible limbs, and charming smile. Every day she practices dance at the park, always seeming to enjoy herself more than anyone else. A man becomes obsessed with her—penniless, friendless, unemployed, and socially inept, yet confident in his overwhelming stamina. One day, he lures Miku into his room and, using his relentless cock, gradually breaks down her resistance until she's reduced to nothing more than a masturbation toy.
