Newlywed young wife Riku is suddenly targeted by a habitual molester inside a bus, and to her dismay, she climaxes from his seductive fingers. Though she tells herself it was a terrible experience, her body aches whenever she recalls it, and she realizes she secretly desires to be molested again. Unable to tell her husband, an uncontrollable lust begins to grow deep within her heart. Riding the bus once more, her body is touched and teased, then she's forcefully taken to a man's place, where she ends up performing taboo sex by sucking the molester's cock. Though her mind resists, she cannot overcome his skill—her pussy is repeatedly made to climax, filled with creampie after creampie. The shocking experience leaves a deep, lasting mark on Riku's soul.
