He could feel the sting of his skin being breached, when Alexia tightened his grip, but he hardly minded the light prick of pain; he had done far worse to others, and had far worse done to himself, even by humans. When he felt the slight breeze of the air disturbed by his wings, he noted he was naked, making him grin around the length in his mouth. He took the extra force in stride, letting one of his hands slither up to cup Alexia's balls, fingers teasing the bottom of his cock as Crowley worked to take him down the rest of the way. He had no fear of choking, as such, but left it up to Alexia to push that extra inch, to give him the pleasure.
