Re: 6th
Somehow this hadn't gotten the reaction Derek had been expecting; he'd thought Stiles would've been relieved - maybe not explicitly happy, but that there'd be something. With a sigh, Derek closed his eyes and found the soap blindly, rubbing it through his hair and across his chest until he was slippery all over. He'd thought being kind to Stiles would've made the human happy. At least if Derek knew he could make Stiles happy, he could choose to do so in the future when he wanted, just as he could choose to punish Stiles.
But the human was frowning, turned away from Derek and giving off wave after wave of mixed emotions that didn't seem particularly pleasant. As Derek rinsed off, he sighed and reached to tug Stiles under the spray of water. "If you want something else, just say so," he said in a low voice. "I'm not - I'm trying-" He didn't know how to articulate what was in his head. It was part exhaustion, but part of it was that Derek knew he couldn't always be kind. He was Stiles' master and Stiles still hated being a slave; Derek wasn't going to let him go. He was going to have to deny Stiles, going to punish him, going to use him. But...he wanted to be able to do the opposite too.
