The expression on Aziraphale's face makes Crowley smirk a little, as he suddenly understands the appeal of this. It's tempting to continue, but he's in a rather nice state of lassitude at the moment, and indulging in a bit of well-earned sloth for a while has more appeal.

He closes his eyes and sighs happily as Aziraphale kisses his forehead, then waves a hand to clear up the rest of the mess between them, leaving him free to scoot in closer. As close as he can get, arm flung over Aziraphale's waist and pulling him in. "Love you."
