Aziraphale would say something like Crowley, my dear, I didn't know you had it in you, but he's very much otherwise occupied. He lets Crowley steer them, the door clicking shut behind them, and lets himself be pressed against that rather convenient wall. It really is convenient, because it lets him focus all his attention on answering to the abrupt but entirely welcome heat of Crowley's kiss, and on slipping his arms around Crowley so that they're flush up against each other.
