In a future where Japan has strict control over citizens' sexual desires, prostitute exclusive actress 'Ryugawa Yui' becomes a sadistic executioner dealing out punishment to those who fail to meet legal standards! Men found guilty of masturbating or engaging in other forms of illicit sexual activity are labeled as 'sexual offenders', and must face the wrath of Ryugawa's hand! Her slow-to-react victims are teased mercilessly until they reach climax, all without any assistance from their hands. For particularly deviant individuals, she goes above and beyond her duties by taking matters into her own hands - literally! Straddling them while showing off her plump ass, she rides them hard in reverse cowgirl position, driving her pussy deep inside them and forcing them to cum. As evidence of their transgressions drips from between her legs, she declares each case closed. Watch as this dominant woman brings justice upon the horny men of tomorrow!
