"Beautiful, Angel mine. Perfect," Crowley mumbled between kisses, mouth starting to trail back down towards the Angel's shoulder. Carefully, he gathered Zira to him and moved to sit up, gently settling a knee between his legs before drawing himself onto his knees. The leg would provide friction, as Crowley craned himself down to kiss at the Angel's wing, along the bone- it was more a gesture of reverence, intimacy than anything entirely sexual. Crowley decided to make this last as long as they could, to make up for six millenia of stubborn denial.
