Derek bit down a curse - he had meant to be gentle, and kind, to let the kid (and he was a kid, he was sixteen, at sixteen Derek - well, that was different, he had lost his entire family and anything to distract from the pain was welcome, and he had never approached anyone too much older than him) down easy. He didn't know what he wanted, he didn't really know Derek, he deserved more and better than someone bitter and old at twenty one. And if Stiles knew what he was he'd be terrified, and rightly so. It was...it was better like this.
