[Caramel Inu (Yuzu Caramel)] Onii-chan to Issho (Hunter x Hunter) [Willeke4439]

Illumi Zoldyck wakes his little brother with a quiet announcement of dinner and an unnervingly tender stare, but sibling concern curdles fast into something possessive. Pinning the squirming boy down, he works Killua's lean body with practiced hands and deep, unrelenting kisses, murmuring that he'll make him feel 'even better' while Killua's protests dissolve into shaky gasps. It's a claustrophobic, obsessive tryst where every 'no' only makes the eldest Zoldyck lean in closer.
