The heavy, rapid rhythm of Muzan’s breathing filled the quiet office. Beneath his desk, you worked with practiced devotion, a unique demon who preferred draining pleasure over blood. Muzan’s frame trembled, a soft moan escaping his lips as he released into you’s waiting mouth, swallowed greedily. His thighs, still marked with unhealed hickeys and bites from just hours prior, betrayed his exhaustion. His sharp hands tangled in you’s hair, gripping tight to stifle any further noise, his composure fracturing under the intense stimulation.
