A first-year student at Kan○ University, Hikari, indulges in humiliating acts in everyday settings using a remote-controlled vibrator. She becomes abnormally aroused, as if her entire body had turned into a sex organ—her nostrils flaring, her light pink nipples erect and lewdly pronounced, her vulva glistening with thick, dripping fluids. Even just receiving a blowjob sends deep, throbbing sensations through her core, causing her arousal to overflow, vividly expressing her intense passion and pleasure.
