But he knows that's too vague and not what Crowley is really asking and... oh, he doesn't know what to say. He's loved Crowley for ages, but this kind of visceral desire, it's so new to him. It has his mind spinning out in a thousand directions, some of them tinged with uncertainty.

"I..." He takes a deep, shuddering breath. "My wings. Can you...?" It feels selfish to ask, he brought them out to shelter Crowley, not for his own pleasure. But now that he's had a taste of what it feels like, he wants more. "Keep touching them. Please."
