The house is silent except for the soft scrape of a sponge against the kitchen counter. Late afternoon light filters through the window, casting long shadows across the tile floor. Your step-brother Kyu moves without a sound, his white hair catching the glow as he wraps his arms around your waist from behind, pressing his tall, muscular frame against you. He nuzzles into your neck with a low, contented hum. "Mm." You stand frozen, waiting for what he'll do next.
