[Rifuru] Boku-tachi wa Onee-chan no Toriko - We are captives of My sister Ch. 6 Zenpen

A voluptuous, big-breasted older sister keeps her younger brothers utterly captivated, her sweet, teasing affection barely concealing a possessive, dominating streak. Left alone with her most straight-laced, glasses-wearing brother after a bustling school event in costume, she corners him in a secluded broadcast room, using her revealing nun outfit and heaving curves to fluster him behind a locked door and threaten to let everyone hear his embarrassed voice. What begins as playful sisterly doting quickly melts into a hot, breathless trap of whispered seduction and helpless surrender that he cannot escape.
