Every day, mother Sumika scolds her only son. Usually calm and assertive, her composure shatters one night when her son secretly records her masturbating and uses the footage to blackmail her. As a result, Sumika is forced to give her son a blowjob, taking his cock deep into her throat and enduring cum inside her mouth. During meals, he torments her with a remote-controlled vibrator, gradually breaking down her resistance. Watching her unravel excites him further, and he eventually demands full sex—culminating in creampie after creampie. A shocking tale of blackmail, deep throat, and incest unfolds.
