[Fuuga] Itsuka no Sono Hi Made Chapter 1

A devoted older sister with soft, ample curves finds her gentle concern for her overworked younger brother curdling into something far more taboo after his coworkers spark a conversation about 'the ideal kind of sisters.' What begins as her tending to him with teasing kisses and whispered comfort—'Aimi onee-chan'—quickly spirals past innocent affection into raw, desperate intimacy, her flushed body writhing against him as she gasps that her 'pussy can't keep up.' Beneath the tangled sheets and frantic rhythm, the forbidden allure of a lifetime of closeness finally shatters its last boundary, leaving two siblings gasping in each other's arms.
