Asami wasn't thinking about the check, either. At least not anymore. There was a brief thought of 'well, that didn't take long,' but it wasn't a bad one. In the moment, it felt natural. And if it felt natural, why should she hesitate? What was the point in waiting?

The corner of Asami's lips turned up in a small smile as she leaned in to return the kiss, lightly. She knew she should keep it brief. It was only a first kiss. But she closed her eyes, faintly tasting chocolate on Korra's full, lightly chapped lips.

Was it the Avatar's first first kiss? She would venture to guess 'yes.'
