Aziraphale runs his fingers through Crowley's hair in reassurance, as if Crowley was the one being penetrated. "I trust you," he says. He trusts him as much as he loves him, or perhaps when it comes to Crowley, trust and love are two sides of the same coin.

As Crowley slowly breeches him and stretches him open, his breath changes, sounds of pleasure escaping on the exhale. "I will," he promises, turning his head to kiss Crowley's cheek. "It's -- oh -- it's very nice so far." He had no idea the human body was so sensitive there. Already relaxed and content in Crowley's embrace, he stretches open easily, taking more of Crowley's finger without any discomfort or resistance.
