Ayane, a married woman frustrated with her sexless marriage, invites a man she met through a dating app into her home during her husband's business trip to satisfy her throbbing crotch. Unable to experience the tingling pleasure with her husband, Ayane repeats the affair while he is away. One day, the lover drugs Ayane and lets his friends toy with her body. Using a low-frequency vibration device to make her convulse in orgasm, large quantities of vibrators and electric massagers drive her to endless orgasms, followed by relentless fucking and continuous internal ejaculation. Ayane gradually goes mad from the convulsing vagina.
