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 of his late wife in Dan, 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, and are directed towards Dan. As Dan is forced into her by her brother-in-law, and despite feeling disgusted by his relentless caresses, the pleasure that consumes her entire body gradually takes over her reason. As his penis thrusts into her vagina, pounding like crazy into her body, she is brought to a climax, moaning uncontrollably. Consumed by guilt and a sense of immorality towards her fiance, she finds herself surrendering herself to her brother-in-law's control, drowning in pleasure... Enjoy the immoral and unreasonable NTR drama in which an innocent bride falls into depravity.
