[Yoshii Tech Sha] NTR Dungeon Captivity [Full Color] [=CBS=]

Two vacationing young women—a shy brunette named Hazuki and her cheerful blonde little sister Moka—are abducted and subjected to relentless group assault, their bikini-clad bodies progressively broken down from tearful resistance to glazed, ahegao-ed surrender. Narration tracks Hazuki's agonizing descent as aphrodisiacs and gang rape erode her will until both sisters are fully claimed as sex slaves, marked with body writing and forced into total obedience.
