Ao no Juuai

The heroine, Ashihara Kasumi, attends a university within Tokyo's metropolitan area. Thanks to her elegant, sophisticated conduct and her alluring body, her superiority is acknowledged by everyone regardless of gender. But one day, those looks of envy reach a turning point and transform into a vortex of lust and jealousy. At her wit's end after being r*ped by the boys she once thought of as friends and torn apart from her lover, Kasumi sinks into an abyss of sexual pleasure.
