'Kiss' + 14 (from Aang, teen verse)
With the end of the war came peace, but also many responsabilites. There was much to do. The members of Team Avatar were scattered across the world now, every one of them helping wherever they were needed with whatever they could. Toph's contribution was her Metalbending Academy in Yu Dao. She didn't 'see' her friends as often as she'd like, but whenever she did, she was hellbent on making the most of it.
Kicking their butt while sparring together just happened to be on that list.
Aang proved himself to be a challenge...but not in the way Toph had expected. In the past, their fighting was mostly done from a distance...at least until she was fed up with his evasive moves, floating and whatnot. To sense him getting closer and closer to her, being more on the offensive for a change had been a nice surprise.
But the kiss that followed his actions was something else entirely. Toph's brain stopped working in that moment. It wasn't her first kiss, but how and why would Aang of all people do that? Was it the adrenaline? Was it her? Did someone finally piss him off enough for him to go 'you know what? fuck it' and start doing things that were the opposite of what one would expect from him?
The confusion and the fact that holy spirits Twinkletoes knows how to kiss disarmed Toph then. The rumble of the earth courtesy of her bending ceased. And the metal pieces in the air, ones she would have flung at the Air Nomad, fell back to the ground.
