BRK-20 Kubo Kyouko: Mother Subjected to Incest Humiliation and Torture

Three years have passed since the illicit relationship between mother and son began. It all started when the son accidentally saw his mother masturbating, which became the trigger for their twisted bond. Helpless against her son's irrational demands, she was pinned down and penetrated with her own erect, throbbing flesh. Though she wished it would end after the first time, her son kept coming back for more. Endlessly continuing their secret affair, she is now subjected to abnormal, relentless sexual training and tormented by overwhelming guilt and shame.
