Chapter 3: He Needs This

It's been a while since Zuko had seen his old friends. Although… this isn't exactly the circumstance he imagined they'd be meeting. In the corner of their rather large living room, Katara and Aang sit with their eyes glued to their rather unexpected visitor.

Zuko coughs to ease the tension. "Uh… Hey guys?"

Katara is the first to speak. "No offense Zuko, but… What are you doing here?"

Aang glares daggers at the Fire Lord. He and Zuko didn't leave on good terms during their last field trip… "Yeah, Zuko." He starts stiffly, "What are you doing here?"

Okay Zuko should have expected this. The last time the both of them went on an expedition, Zuko kept moaning Katara's name in his sleep. What? It's not like he can control his dreams… Or thoughts… Or late nigh fantasies he uses when he's al- You know what? screw it, Zuko's had the hots for Katara since he was a teenager, why is it a big deal?… Okay maybe the fact that he was moaning the name of his companions wife, wasn't exactly helpful. Right, anyways… "I was just in the neighborhood…" That was a lie.

Katara looks up at the firebender with an incredulous look on her face, "Zuko… You live two continents away… and you have two suitcases in your hands. But that's not even the weirdest part." She pauses. "You literally barged in here, completely disregarded me and Aang and went straight to our children and said 'Wanna ride a dragon?' and then said dragon took off to La knows where. And you just came in here saying 'what's for dinner?'"

Zuko scratches his head sheepishly. Yeah that was probably not the best move. "So uh-"

"Where's our children Zuko?" Katara asks sternly with her hands on her hips.

"They're fine! Just with Uncle. They're going to be spending some time on Ember Island for a few days."

Aang continues to stare furiously at Zuko, not saying anything.

Katara Stares at the Fire Lord in Shock. "You… WHAT? DAYS?"

"It's necessary, I don't want the kids to see."

That got Aangs attention. "See what?"

Here goes nothing. "I need to fuck Katara."

Katara spits out the drink she poured out of nowhere and starts coughing. "Here?"

Aang clenches his fists. "Yeah! How cou- Wait? did you just say 'here'?"

The waterbender pretends to cough. "Did I say here? I meant why?"

Zuko sighs, "Look I need an Heir and I don't want to fuck Mai. Agni! Please don't make me fuck Mai. She's such a bitch. Oh. My. Gods. I can't even get it up to her. But Katara. You. I've always been able to get it up for you. Agni, the amount of nights I've imagined it was you instead of Mai… Aang can attest to that."

Aang stares shell shocked. "How dare you?" He starts to get up, but a hand on his lap stops him

"Aang… He needs this."

"Katar-"

"Aang HE NEEDS THIS." She points to a very sad looking Zuko, "look at how he's suffering."

"Yeah Aang don't be Dick!… I mean… I'm really sad. Help…"

Katara walks over to her old friend and rubs her fingers along his thigh. "Don't worry Zuko, I'm going to make you feel so much better… I'll never turn my back on people who need me."

Zuko groans. "Fuck! I love it when you talk dirty to me…" He strokes her cheek and she purrs. "Remember that night on the beach. When we almost… You know…"

She blushes at the memory. The two of them sparring until he fell on top of her, effectively pinning her to the ground. She can remember everything. The impressive length of his cock pressing into her slick heat… That was the closest she ever got to an orgasm… "Oh yes" She gasps. "I remember. Do you remember that night in the palace when we told Aang we were 'having a meeting?'"

Aang stares at his wife gaping like a fish, as she slides her breast bindings away from her chest.

Zuko stares at her chest with hunger. Never before has he seen anything more perfect. His cock seems to agree as it aches to find friction. Shaking his head to refocus, he can see Aang staring at them with shock and smirks. Without further hesitation he dives in an latches on to her breast, while looking straight into the air benders eyes. He hears the moans coming from above him and feels hands frantically trying to undo his shirt.

"Oh! Zuko." Katara has never felt so wonderful in her life. But she wants more. Frantically she slips her hand under the waistband of her lovers pants and wraps her hand around his cock. She has to stop herself from yelping at the size. Never in her life has she felt something so warm, thick, long and hard. Aang's was… Alright? But Zuko… La she doesn't know if she'll be able to walk after this. Or if she even wants to…

Zuko stills. Feeling her hands on him is the most wonderful thing he's felt in his life. Agni! He needs more. without warning he grabs onto her ass and moves her to straddle his hips. he hears her yelp of surprise. But that yelp quickly becomes a moan as he grinds into her wet center. He smirks as he feels how ready she is for him. He moves to her hear and nips at the lobe before whispering. "You're so wet Katara. Does he make you feel like this? Or is it just me?"

Katara arches her back at his words. "It's you! Just you!"

Aang wants to move but he can't all he can do is stare as his wife moves off Zuko's hips and takes his member into her mouth… She only does that for him on his birthday! Oh shit… He's gonna lose her isn't he?

"Shit! Katara!" Zuko groans. The scrolls were right. Water benders give the best head. She must be controlling her saliva because. "Agni." Watching as her head bops up and down his shaft is the most erotic sight he's ever seen. That is until she look up at him with lust filled eyes and moans against him… If he doesn't fuck her. He's going to lose his mind.

Katara continues her ministrations, taking him in as far as she can. She controls her gag reflex and takes him into her throat and sucks.

"Shit! Katara, if I'm not inside you in the next few seconds I'm going to lose it." That seemed to get her attention. Because no more than a second later she's completely bare and sinking on to him with a silent scream. As he grips her hips for dear life. "Fuck…" He pants.

La! Katara can feel her insides expand to accommodate the monster attempting to fit in her tight cunt. She lets out a scratchy moan as he hits the spot she only ever thought of as a myth. Aang never got anywhere near that place and Zuko is doing it without even trying. And tears start leaking from her eyes because, fuck… There's no going back from this. This feeling. The closeness, is unlike anything she's every felt, and its mind shattering.

Zuko's cock feels like its being milked from the inside out. Is this what it means to fit with someone so perfectly? He knew she'd be tight… She's married to Aang after all, and he knows what the avatars packing… But she's not just "tight" she's tight, and soft, and wet, and- "Perfect." He mutters. His eyes are half lidded in pleasure and he can faintly hear the harsh pants coming from the goddess above him before instinct guides them, and they start to move. "Katara!"

Katara starts riding him for all he's worth, because La! she needs him to hit that spot and, "Oh! Yes! Right there!" That seems to be the only encouragement he needs because suddenly he's ramming into her with a mind numbing speed. She has to do her best to keep up. "Zuko!"

The feel of her wet delicate folds, the screams of his name almost take him over the edge… if only he didn't just render something important. "Shit." He pants as he continues to thrust into her. "I… Forgot a… condom"

Aang balks. "Condom? You said you need an Hei-"

She snarls, "AANG!" I told you!" She Gasps as Zuko continues to hit her spot. "HE. NEEDS. THIS!" She says in between thrusts. "Why are you still her- Oh fuck!"

Zuko grunts, "We're doing… Fuck, Katara! A practice run." It's almost over, he can feel it in his balls as they tighten with his inevitable release. And judging by the way his water bender is thrashing and moaning above him, she's close too.

Aang gives up and leaves, He never thought, it would take this long… It only takes him thirty seconds. At least it sounds like she's not enjoying herself. Sex is never supposed to be loud It never was with him, so that must mean Zuko was bad at it… Yeah! That's why it's taking so long, he just cant beat the Avatar! Ha!

Zuko watches as the annoying Airbender finally leaves, and finally brings his mouth to his lover as they finally reach their release. Together, they swallow each others moans and hold onto each there for dear life as they come down from their joined high.

Katara is the one to break the kiss. She needs to breath! La, that was the best experience she's ever had in her life. And she gets to have more of them… Until she gets pregnant… Maybe during to help with her hormones… Maybe after, to help with postpartum… Maybe for as long as she damn well pleases! It seems the Fire bender has the same Idea, because when she looks down, she can see his cocky grin but his eyes have something else…

"Hey." He says peacefully.

"Hey." She smiles at him before running her hand through his hair and towards his scar. He leans into her touch and purrs.

"We're doing that again right?"

"Oh! Definitely!"

Five Days later

"Oh! Zuko!" Katara screams from the other room as she reaches her third release. It's been the best five days of her life. After the first four times. Aang decided he was going to just stay in the guest house for a couple of days. Katara was more than fine with that, as she got Zuko all to herself, and they christened, every. Single. Room. Zuko, she found out, was an absolute animal. But she was more than willing to be his prey… Until she decided it was his turn to be hers. Together they learned each others bodies inside and out. She never knew someone could use their mouth 'down there.' But she was coming to realize that, it was one of- if not is Zuko's favorite thing to do.

Zuko's been in heaven. He never thought he'd actually get Katara to agree to carry his child. Let alone get her to agree to sleep with him. This was better than he ever imagined. Looking at the smiling waterbender next to him, he's quick to pull her close and cuddle her to his chest. They've gotten close. Close enough to be considered lovers. But he knows this is just a fantasy they'll have to break at some point for reality.

"Zuko?" Katara sighs.

"Yes?" He can hear the sorrow in her voice.

"What are we going to do?"

He sighs, and turn over onto his back "What do you want to do?"

"I…" She blushes "I want to keep doing this." She says truthfully.

Zuko stills. She wants to keep being like this? This has to be a dream… "What do you mean by 'like this?' Do you just want to keep fucking? Or…"

Katara's face becomes redder. "I love the sex, but… what I meant… was the closeness. I… like being like this… With you."

His heart feels like it's going to give out. "I like this too…" He turns to face her while taking her hand in his.

Bumi and Kya walk into their home and call out "Mommy? Daddy?" Together, they walk in with a bunch of souvenirs in their hands and a smiling iroh behind them.

Iroh notices the furniture is completely disorganized and some even broken… What happened here? Iroh had no Idea why his Nephew demanded that he take care of Master Katara's children, but he loved them as if they were his own grandchildren… Not like his Nephew was going to give him some anytime soon. And it was a shame Zuko didn't go after her when he had the chance, they would have made beautiful babies. But that's not what should be on his mind. Because something seems off… Suddenly a crash can be heard from the other room.

"Shit! I forgot they'd be coming back today." Zuko says in hushed panic.

Katara hastily puts on her clothes, not bothering to check if they're even on right. "I'll take care of this. Stay here."

"Kya! Bumi!" Katara looks at her two children frantic to act normal. And not as if Zuko was just pounding into her with all his might…

Iroh raises an eyebrow at the water bender appearance. Her hair is a mess, she's wearing her dress backwards, and her shoes are on the wrong feet. and looks completely out of breath. Iroh's not completely sure, but he thinks he heard his nephew. But that would mean…

Bumi looks at his mother with confusion. "Mommy, why are your clothes on backwards?"

"Yeah." Kya continues, "And why did Uncle Zuko, tell us you were going to be riding his dragon before we left?"

Katara's face pales and can see Iroh has the same reaction as she does, because neither of them know how to respond.

"Because, kids" Zuko comes out from the other room fully dressed. "I have a very special dragon only your mommy can ride." He winks and Katara nearly faints.

Iroh's jaw hangs open at the realization of just exactly what Zuko and Katara had been doing for the past few days. But then his face softens and his shock turns into glee. "Am I getting Grand-babies?"

Zuko chokes on the water he just so happened to be drinking. "Um well…"

Katara smirks. "If all goes according to plan…"

Now it was Zuko's turn to blush. But Iroh's smile just grew wider. So what the Master Katara and his nephew were having an affair? He was finally getting some Grand-babies!

Bumi looks up to his mom with concern. "Uh… Mom? Why is dad crying on our front porch?"
