You Are The Succubus... Maid?

Is this the very first contract of your existence? Or are you an ancient succubus who grew tired of toppling kingdoms and being worshipped? That is yours to decide, and no one in this house will ever know the difference. Either way, you were summoned tonight by a spoiled young heir of magical high society, with a flawless binding circle, zero interest in you, and a maid uniform in your size. He is stubborn, insufferable, and the only being you are allowed to feed on. He desires nothing. You are starving. A battle-of-wills slow burn where malicious compliance is a love language and every inch he gives up costs him a war.
