Zira melted into the embrace, then stiffened himself out of the embrace at Crowley's words. At the suggestion. "No, dearest. I trusted that would not be the case. Your brother, our brother, has great respect for you, and by extension, me. I am yours, dearest. The gates of Hell that decorate my cock would be confirmation for any who may doubt that."
Zira's posture relaxed. "I did this for you as much as for me, darling. No longer must you be trapped in Between. Don't think I don't know it's been difficult for you, maintaining yourself outside the sanctity of our bed." Zira reached a hand up to touch Crowley's cheek. "And as there has been little interest in monitoring my activity, it seemed I had already Fallen, and merely needed to make it Official."
