Stiles rolls his eyes at Derek's grousing because seriously? It wasn't as if anyone had lived there since the remaining Hales had left. But his expression turns thoughtful as Derek keeps speaking.
"That's why I smell 'wrong,' huh?" he guesses. "You don't like smelling other people on me."
He smiles, then, soft and fond, because his boyfriend is a dork. "You are so gone on me." He tugs on Derek's hair and shoulders, urging him back up his body, wanting a kiss. "I can't believe I thought you weren't into me," he adds, his tone teasing. "Your wolfiness betrays you."
