Married Arisa loves streaming her masturbation while her husband is away, showing off lingerie, using toys and basking in viewers' praise. Her unemployed brother-in-law discovers the broadcasts, records them and uses the footage to blackmail her. Unable to resist, she is ordered to masturbate on camera, sexually harassed during housework and finally assaulted in her sleep. She despises obeying him, yet her body reacts with growing heat as her face is coated white with his cum.
