29-year-old single older sister "Iori" leads a busy life working in accounting at a company, and hasn't had a boyfriend for about three years. She jokingly admits, "I might be a little twisted... w," but her tone reveals genuine inner worries. Unable to form casual sexual relationships and struggling to relieve herself alone after a long dry spell, she decided to enter the world of AV production. Just having a male actor sit beside her makes her heart race and fidget nervously—an innocent, pure romanticism uncharacteristic of someone her age. Shy and inexperienced, she feels extremely awkward being photographed in lingerie. Yet she possesses an ideal slender figure with well-shaped breasts and a firm, round ass, and her sensitivity matches her intense libido—her reactions are incredibly cute as she repeatedly cries out, "No... it feels too good... I can't take it anymore! I'm done!" Witness the irresistibly vulnerable lovemaking of this sexually charged older sister.
