[Special Edition] The bond between sisters ascends into eroticism! Introducing the J○ duo of Hinako-chan (younger sister) and Mao-chan (older sister). Mao, the elder sister, has an elegant face resembling their mother, and despite her petite frame, she boasts a delicate, feminine build—her particularly voluptuous curves adding to her erotic appeal. Hinako, on the other hand, inherits her father's refined features and possesses a model-like slender figure, creating a striking contrast that heightens their sisterly allure. From the very moment their intimate connection begins, an erotic atmosphere fills the air. This time, the story unfolds while their older brother is asleep—a forbidden, special moment. The older sister teases with her toes, gently stroking and sliding them together, or uses the soft flesh below her knees to envelop and piston over him from various angles, exploring pleasure in every way. The two sisters also gang up on him, simultaneously performing passionate blowjobs, escalating the lewd scenes one after another. A unique experience only possible within a family, an after-school secret they can't share with anyone else. With relentless erotic intensity, the scene culminates in creampie after creampie and a massive facial, pushing boundaries and delivering an utterly uninhibited, deeply sensual masterpiece.
