Smirk
Summary: The one thing she was defenseless against. Of course, he didn't need to know that.
Note: This took a total 360 from its original story. Smirking is just used in so many stories with them it's hard to find some sort of originality. Just, thank you reference materials.
Katara was by no means a weak willed woman. It was a fact she prided herself on and, despite people's take on it, enjoyed flaunting when she had to.
Growing up in the Southern Water Tribe there had never been a chance to do so, you see, and in her younger years Katara admitted times she had to repeatedly remind herself that she was young.
More often than not it was her subconscious' Aang voice that reminded her.
Case and point, the loud celebration of three top graduating students at Beifong Metalbending Academy had a nineteen year old water tribe wallflower nursing her drink while the Avatar and his Sifu livened things up.
Her boyfriend had been 'persuaded' into an earth rumble that escalated until both masters lay sprawled outside amid student and parental praise.
"Sifu Toph, you were incredible!" Penga rounded on her master before fluttering her eyelashes at the Avatar dusting off his robes, " You too, Avatar Aang."
Toph spit out some excess rubble, "Don't let Sifu Sugar Queen see whatever it is you're doing, Lily Liver."
At the more or less mention of Katara, Aang ceased his stretching to seek her out. Sure enough, sitting in the same spot with her tea and comfy looking Momo on her lap.
"If you'll excuse me." Aang bowed aside the makeshift ring and air scooter-ed away from Toph's snort.
Aang's breeze lifted Katara's lips to a grin, only growing when his shadow bowed over her.
"Mind if I join you, Sifu Katara?"
Katara elevated her gaze to his, accounting for that playful, suspicious smirk spreading prior her answer.
"It'd be an honor."
She couldn't ignore the thrumming in her heart as Aang's smirk only widened. He pressed their shoulders together and proceeded to scratch Momo behind his ear.
Total nonchalance. Katara eyed him suspiciously.
"Having fun?" She joked, rubbing a small bruise on his jawline.
Aang nuzzled her palm, "I could ask you the same."
Katara pouted to distract herself from his romantic pecks, "I'm having fun."
"Watching me?" He asked innocently.
"I always have fun watching you." Katara defended before she realized her slip up.
She felt his smirk grow in her palm and snatched her hand away with a surprised scoff.
"Fishing for more compliments are you? Haven't you had enough praise showered on you for one night?"
"Obviously. But now I have to shower you with compliments." Aang whispered against her neck.
Katara gulped, "Oh do you?" her cheeks heated immensely. His smirk was now rubbing beneath her earlobe.
"Yep. So, what do you say, Sifu Katara?"
Yes, Katara was not a weak willed woman by any means.
"What do I say to what, Pupil Aang?" And rarely did she stutter.
But when Aang looked at her… and held her definitely not quivering body just right… and pressed his smirk against her lips…
"A shower."
She certainly didn't feel like she had her usual strength.
