“This is just sex. That’s all this has to be.”
It had been enough to break down the barrier keeping them apart, the wall of tension holding Derek still and distant even as his eyes raked over Stiles with a heat neither of them had ever addressed until now. It had been going on for longer than either of them could admit, longer than they’d probably even noticed.
But Derek was Derek and he was never going to do anything about it on his own.
