[Fuuga] Fushidara na Ani Imouto Chapter 1

A shy bespectacled older brother and his earnest little sister, whose tenth birthday he insists on celebrating as their belated anniversary, find their innocent cake-cutting derailed when the bathroom door sticks and awkward, flushed proximity gives way to something far more consuming. Fuuga's tender, slow-burning tension erupts into raw, desperate intimacy—trembling confessions, trembling hips, and trembling sheets—as the petite twin-tailed girl loses the innocence she clung to for ten long years. The quiet melancholy of the final page, with its cloudy sky and unspoken wishes, leaves the door wide open for whatever forbidden afterglow awaits.
