That contact, no matter how brief, made her wings stiffen all over again, and made her blush and break away from the kiss. She could hide the blush, but her wings just didn't want to calm down this time. Awkward.
"So. Uh..." she wasn't going to stammer. Saying 'uh' wasn't stammering, it was a delaying tactic, dammit... and considering words weren't really working, she just moved to kiss her again. It worked better.
