Title: Committed

Pairing: Zuko/Katara

Rating: M

Summary: There are some sins in life worth committing.

A/N: I found myself getting stuck on the Zutara Month (2012) prompt "Pride". I then started thinking along the lines of the 7 Deadly Sins, and this idea came to me. Each installment will be based on/feature one of the 7 Deadly Sins. There's nothing like being naughty ;)

Lust

When I decided to show Katara the Fire Lord's private office, I didn't think anything of it.

We were catching up at the ball celebrating our return to the Fire Nation. Honestly, ever since peace had been declared among the four nations, I felt like a ball was thrown for every damn thing that we did. I wouldn't have been surprised if a ball had been organized to commemorate the first time I used the Fire Lord's private bathroom.

To be fair, it had been months since I've set foot in the Fire Nation. Soon after my coronation and the end of the war, I had gone back to traveling around the world- peace meetings, peace treaties, peace summits, peace everything. Peace was a lot of work.

Uncle Iroh has been gracious enough to fill in for me during my absence. I trust him more than anyone. And the traveling part had been nice- a part of me felt scared at the prospect of ruling the entire nation right off the bat and be separated from Aang, Katara, Sokka, Suki, and Toph. At least with this traveling thing, I had been able to take this peace thing one step at a time with each place I visited and still get to see my closest friends on a semi-regular basis.

Plus, it was important to me that I pay my respects and offer my apologies on behalf of the Fire Nation in person. Some things just can't be done via messenger hawk alone.

So now, all of us were reunited at the Palace, celebrating our safe journeys and I guess the official start of my claim to the throne (since I'd actually be sitting on it now).

Katara had found me, sipping on some wine as I surveyed the hall of guests. She had joked that I looked so serious for being at a party to which I could only grunt in reply.

Some habits die hard.

It was nice to be talking to Katara again. What with traveling and Fire Lord-ing, interactions with me were really touch-and-go. Katara was busy herself- she was studying medicine from all four nations, thinking up ways to improve her healing and global medicinal practices in general. Not to mention the fact that she was in constant communication with her father and Chief Arnook, helping the process of rebuilding the Southern and Northern Water Tribes, even though she wasn't even there. Hearing her talk about all the various projects she was involved in made my Fire Lord duties pale in comparison.

She giggled when I told her this. She then suggested that she show me my private office.

Oh, how it all seemed innocent at the time.

I agreed and the two of us downed the rest of our drinks and slipped out of the grand ballroom, everyone else too preoccupied with the festivities to notice.

It must have been the wine because suddenly it was all a great game trying to sneak into my own office. The two of us were having the time of our lives dodging guards and hiding behind pillars, using our stealth in what had felt like ages. When we finally reached my office and closed the door behind us, I felt giddy and lightheaded and not at all expected Katara to push me up against the door and begin rubbing the front of my pants.

Oh. Oh... what was happening? What-

My mind was screaming at me but my mouth just hung open. I must have looked like a fish out of water. My mind screamed even further when she brought a finger to her lips in a shushing motion and suddenly dropped to her knees, freed me from the confines of my pants and took me in her mouth, all in one fell swoop.

What. What. Oh my- oh- what-

I couldn't think. Words were not forming themselves right. Coherent thought quickly floated out the window as pure physical pleasure took over. It took all my willpower and then some to not thrust, to not grab her head. The feel of her tongue, her warm mouth around me was... amazing.

I stifled a moan in the back of my throat. There were guards just outside the door. I was also scared that if I made any noise, all of this would just disappear and it would all have been a dream. A wonderful amazing dream.

I chanced a look down and was met with the sight of Katara's mouth encircling me, her eyes looking up at me with a certain look that I know I will never forget until the day I die. I bit back a moan again, throwing my head back, away from the extremely erotic sight of Katara going down on me and doing delightfully wondrous things to me with her tongue. She let a soft moan, the sound reverberating around me inside of her mouth.

This was definitely not going to last long.

Uncle Iroh. Uncle Iroh naked. Uncle Iroh back at the hot springs-

All thoughts of Uncle Iroh immediately disappeared as complete pleasure overtook my body and all I saw was white light behind closed lids.I gasped, I sighed, I bit my tongue, I bit my lip, all to stop myself from crying out- from breaking our agreement.

When I was finally able to open my eyes, things started clicking into place in my mind and I felt a deep blush start to bloom up my neck and to my cheeks.

What just happened? What do I say?

No one had ever done that to me before. Also, I never would have expected Katara, of all people, to do what she just did. Was this the same girl who I had been talking about politics with not too long ago?

Katara stood up, casually dusting off her knees and discreetly wiping the corners of her mouth. I must have been gaping again because she smirked, an extremely devilish sort of smirk, and promptly closed my mouth with her finger underneath my chin. She slowly opened the door and peeked outside, seeing if the coast was clear.

She glanced back at me again, her blue eyes playful, the smirk still on her face, and just like that, she stepped out and was gone.

I sank to the floor as soon as the door clicked shut behind her, my legs finally buckling as my head processed everything that had just happened. After a few minutes, I finally stood up, pulled up my pants and rearranged my clothes to resemble something close to decent. As I walked back to the grand ballroom, my head whirled a million different scenarios a mile a minute. What was I going to say to her?

I was greeted enthusiastically by Uncle Iroh when I returned, only half-listening as he chattered on about so-and-so and how he had set up a meeting for me tomorrow and whatnot.

My eyes searched the room for her, finding her in a millisecond. She was laughing heartily in a group composed of Sokka, Suki and Toph.

She looked completely normal.

Like nothing had happened.

Like her mouth didn't just-

She must have felt my stare because she glanced up, caught my eye, and smiled that smile again.

My smile, I realized.

A goofy look must have sprung up on my face because the next thing I knew, Uncle was asking if I felt okay, pressing his hand against my forehead, expressing how I felt a bit warm.

Yeah, I was definitely warm.
