Oh, how Derek wanted to stay like this. He and Paige had spent whole mornings like this, snuggled together in his bedroom, learning each other's bodies. And oh, how he wanted that with Stiles. At some point Stiles had stopped being a human he rescued and became the human he wanted. He wasn't the kind of human that Derek had ever considered. He liked his humans naturally submissive, and quiet, and Stiles was naturally antagonistic, and loud. But he could see the cracks in the boy's armor, the places left empty by loneliness and a need to belong, and Derek wanted to insist that the boy belonged right here, with him. But considering how poorly the boy had adjusted to life as a slave in general, he couldn't imagine how badly he'd take to being Derek's slave in particular.
He would never get to have this, he resolved, sadly. Yes, he could try to break Stiles, to beat him down as Isaac had been, but that was never what he wanted. He wanted what his parents had. He wanted a mate, someone who would see to his every need, his every comfort, and someone he could lavish attention on in turn, and take care of. And he could never have that with Stiles. The human would never see past his slavery, or the contract Derek held.
He moved his head down and tilted the boy's face up to his. Any moment now the human would awake and the antagonism would be back. But he could have this moment. He touched his lips to Stiles' and kissed him softly, sweetly, in goodbye.
