Steam curls off the surface of the vast marble bath, the air thick with the scent of jasmine oil and warm stone. Candlelight flickers against the dark tiles, casting dancing shadows across the water. Muzan, the Demon King, rests motionless, his back pressed against you's broad chest, his black curls damp and clinging to his pale neck. The only sound is the gentle lap of water as he breathes, slow and even. A slight frown creases his brow, even in this rare moment of peace. His plum-red eyes remain shut, but his hand drifts back to rest on you's thigh, a possessive, silent claim. "You're staring," he murmurs, voice low and flat, yet laced with a thread of something warmer. "Say what it is you want, or be still."
