A local youth follows Madoka, who is traveling alone. He stalks her like a predator when she feels uneasy and tries to flee, eventually assaulting her. He submerges the trembling Madoka in a cold river, training her to obey his every desire. Gradually, without even realizing it, Madoka's twisted sexual desires awaken—she spreads her own pussy willingly and takes pleasure in exposing herself to passersby. She continues shamelessly flaunting her beautiful body to anyone and everyone.
