Married Tomomi loves to stream herself masturbating and be fawned over by viewers. Even on the day her husband was away on a business trip, she continued streaming as usual, showing off her underwear, which viewers had said was sexy, using toys to orgasm, and getting lots of compliments on how cute she is. But one day, her unemployed brother-in-law finds out about her streaming and exposes her weakness. He shows her the screen of the recorded stream and, unable to resist, she gradually becomes at his mercy. He films her reluctantly masturbating on his smartphone, sexually harasses her while she does housework, and finally attacks her in her sleep and rapes her. Tomomi hates being at the mercy of this creepy, unattractive man, but her body heats up and she starts breathing harder and harder...
