Prestige exclusive actress Nonoura Dan is destroyed by her fiance's younger brother. Dan visits her fiance's family home to celebrate his father-in-law's birthday. Dan, who is cheerful and considerate, sees a resemblance in Dan's father-in-law, and treats him with exceptional kindness. This "special treatment" strongly stimulates feelings of inferiority and jealousy in her brother-in-law, who has always been an outcast in the family. Eventually, these feelings transform into an uncontrollable, twisted desire, directed towards Dan. As her brother-in-law presses her forward, Dan feels disgusted by his relentless caresses, but the pleasure that consumes her entire body gradually takes over her reason. As his penis thrusts into her vagina, his frenzied thrusts imprint on her body, she is brought to a climax, moaning uncontrollably. Consumed by guilt and a sense of immorality toward her fiance, she finds herself surrendering herself to her brother-in-law's control and becoming immersed in pleasure... Enjoy the immoral and unreasonable NTR drama in which an innocent bride falls into depravity.
