Sokka and that Goddamn Fucking Mouth

Summary:

Zuko thought he'd spend the afternoon in his living room with roommate Sokka, mindlessly scrolling through TikTok until when Sokka asks for pizza money, something in Zuko snaps.

That goddamn fucking mouth of Sokka's breaks Zuko, leaving him standing hard in their living room before retreating to his bedroom.

---

Sokka says something sexual and causes Zuko's brain to fry, the sexual tension is strong.

Notes:

Hi, welcome to my first smut fic. It started out as a fluff piece and then uhhh... Well now it's porn.

Based on a TikTok!

It's not beta read.

Work Text:

Zuko lays unceremoniously on their old couch that he's still pretty sure that Sokka found on the side of the road, his head propped up by one of the many squishmallows that reside in their living room. His one leg bent up to rest along the back of the couch while the other stretched across the cushions. With phone in hand, Zuko scrolls mindlessly through that clock app as Sokka liked to call it, catching up on the 37 videos that his best friend had sent him.

"Did you catch up yet?" Sokka asks from his place on the matching oversized chair. How he managed to find and bring home a matching set of roadside furniture, Zuko will never know. It took a week of Sokka continuously scrubbing the fabric before Zuko deemed it okay enough to let it grace his ass.

Though, he really can't complain much about where they get their furniture, both men strapped for cash and scrounge enough from their day jobs for the important things like rent, food, and of course, squishmallows.

"Jeez, no, not yet, you sent like 300." Zuko replies with a scowl.

"It was only 10 today, it's not my fault you let them pile up." Sokka says as he shifts and tosses his legs over the side of the chair, "and you have to watch all of them, they're important and I need you to see them."

"I'm pretty sure they're not that important." Zuko says, scrolling through a pausing on one with a duck in a coffee mug, "I mean okay, that one maybe, but I don't get all the gachapon ones you sent."

Sokka gasps and sits up in his chair un-bisexually with both feet planted on the hardwood floor that really ought to be swept. His hands brace the edge of the coffee table of equally mysterious origin as he leans forward to look at the audacity that is his best friend.

"How do you not get them? They're so fucking cute, like they're just so tiny, and little, and small, did you not see the one of the sad cat sitting on the bus bench? That little face, oh my goodness, buddy, it's my everything," Sokka starts on his ramble about the inherent cuteness of miniature items and the absurdity of some of the figurines.

The two lull back into their usual rhythm when they both aren't at one of their many jobs. Zuko had gotten home not too long ago from the Jasmine Dragon, bringing with him a matcha latte for himself and an iced sparkling yuzu water for Sokka. Both mostly drunken and not forgotten, leaving new water rings on the coffee table even though there's coasters just inches away.

"You wanna split a pizza?" Sokka asks, lowering his phone so he can peak out the window above him. The sun is lowering in the sky, the clouds painted a hue of pinks and oranges that Sokka says reminds him of a filet of salmon.

Zuko let's the phone fall out of his hand and on top his stomach for a moment as he thinks about Sokka's question. Only for his belly to grumble in response for him.

"I'll take that as a yes, I'll get the usual. You got cash?" Sokka asks.

Getting up from the couch, Zuko walks over to his bedroom where he had tossed his wallet when he changed out of his clothes that smelled too strongly of tea and coffee. With a cash in one hand and phone in the other, Zuko makes his way back to Sokka somehow not bumping into anything as his eyes remain on the phone.

"Here, this should be good right?" Zuko absentmindedly asks.

"Hey, look me in the eyes when you give me money, sweetheart," Sokka says as he takes Zuko's hand in his, drawing it back to grab the half folded bills.

Zuko's head snaps up at the response and eyes lock with those baby blues just in time to see Sokka wink and stuff the cash down his shirt. He remains locked where he stands even as Sokka turns to dial the local pizza place to put in their order.

With his head empty, Zuko becomes very aware of the rest of his body. There's a heat in his shoulders that travels up the back of his neck, a fluttering in his belly, a stiffness in his pants. This is not the first time they've flirted and teased each other, they do it all the time, it's what buddies do. Two guys just being pals and playing with one another.

Sokka was off limits though. To Zuko, that was his rule, don't fall in love with your best friend. A rule he'd broken it along time ago, even if he still denies. But he knows it. Toph knows it. Hell, even Katara and Aang know he's in love with Sokka.

Sokka raises an eyebrow at the Zuko that is just standing there with what he thinks is an annoyed look on his face. He waves at Zuko, the movement of his hand breaks him free and he manages to mouth that he'll be right back.

Making sure it doesn't look like he's desperately trying to hide a growing erection and seeking refuge, Zuko walks stiffly but quickly back to his bedroom. He manages to close the door quietly and flop on the bed that he had forgotten to make that morning. He softly screams into his pillow all his horny thoughts and frustrations.

But one thing remains to be dealt with and it only starts to ache more when he tries to will it away.

"Goddamn it, fucking Sokka, and that goddamn fucking mouth of his," Zuko grumbles to himself as he rolls over onto his back, one hand snaking it's way into his grey sweatpants.

He lifts his head up to look down at his pants before flopping back, groaning in additional frustration, there was no way Sokka could have not noticed it earlier. The grey sweatpants hides nothing, it only puts everything on display for everyone to see. These damn pants and their inability to leave things for the imagination, Zuko curses them as he lowers them down his hips.

After fishing for the bottle of lube from the nightstand, Zuko closes his eyes as he takes himself in one hand. He swipes his thumb over the slit that leaks with precum as he replays the scene over and over.

Sokka with those eyes that sparkle like crystals, as blue as the ocean, hell, they look like the universe with galaxies and stars and space dust, and it all makes his stomach flutter. Zuko thinks about those eyes on him, especially now, those eyes watching him as he touches himself to the thoughts of his best friend. Would he look at him in disgust? Maybe, if for once in his life he was lucky, those eyes would be blown wide with lust, want, desire.

His hand strokes fast up and down his length, trying to come quick before Sokka gets suspicious about where he's gone for so long. Zuko thinks of that goddamn fucking mouth, those lips pressed against his, his hands cradling Sokka's chest. He wonders what Sokka would feel like sitting on his dick, his cunt hot and soft as he rides him into oblivion.

Or better uses for that goddamn fucking mouth of his, the thought of those lips stretched around his dick sending Zuko flying high.

Fuck, fuck, fuuuuck, Zuko thinks as warmth pools in his lower belly and snaps, cum mixing with the lube that stickies his hand. Fuck his mouth.

Zuko lays momentarily clearheaded and blissed in his bed, cock going soft and hand a mess. It helps, the horny thoughts and sexual frustrations faded a bit, but it's not enough. It's never enough.

He wants to have Sokka pressed up against the wall as his fingers travel across the topography of his body, his lips tasting the hills and valleys. His fingers dipping into the dark wet crevice as he listens to the sounds that that mouth makes. Zuko wants to hear Sokka whine, hear him moan, call out his name dripping with the need for more.

He wants to have Sokka on that couch picked up from the side of the road. That tall beautiful man above him as he slowly takes Zuko into his cunt, eyes looking down at him before they slip behind eyelids shut in pleasure. Head snapped back in ecstasy while Zuko's fingers dig into his hips.

He wants Sokka in his bed, to be sandwiched between the wall his bed is shoved against and the warm body of his best friend. Laying there in a post coitus glow, heads in the clouds as limbs remain entangled and fingers lazily graze the soft skin beneath where they lay. Words spilling out in whispers as voices lost in the earlier pleasures and kisses pressed against cheeks, noses, foreheads.

Zuko shucks his boxers and pants back on and peels himself up and off the bed. He grabs a tissue from the near empty box that resides in his nightstand to wipe away any evidence from his hand. He tosses the tissue into the wastebin by his door and steps out into the short hallway, making his way into the single bathroom to wash up. He can't go into the living room smelling like sex and the shame of getting off to the thoughts of his long time best friend sucking him off.

Cleaned up, Zuko steps out of the hallway into the living room to see the pizza box already sitting open on the coffee table. He didn't realize he had been in his room for that long and hopes Sokka's brain is too focused on the food in front of him to question where he was.

"Ya good?" Sokka asks looking up from the slice he just grabbed.

Zuko plops down on the couch close to the pizza and Sokka and grabs a slice, his stomach rumbling at the smell of cheese, pepperoni, and grease.

"Yeah, I just felt like… uh… meditating," Zuko replies before taking a bite.

Sokka nods and gives him a thumbs up, "cool cool, thought I was gonna have to eat this whole thing by myself."

"You make it sound like a problem, I know you could eat this all in one sitting," Zuko scoffs.

"I'll have you know I'm a growing boy," Sokka gasps, "though, I should have ordered sausage on it, I'm in the mood for something meaty."

Zuko feels his cock twitch in response and tries to maintain his composure as he shoves the slice of pizza into his mouth. That goddamn fucking mouth of his.

"This is good though, so hot and saucy, I could fit the whole thing in my mouth," Sokka says, his eyes fluttering back in happiness as he bites down on another slice. "Oh, you got sauce on your face, let me get that."

Sokka reaches across the corner of the coffee table, his thumb wiping the glob of tomato sauce that painted Zuko's chin. Those stormy blue eyes stay locked with those golden double suns of Zuko's as brings his thumb back. He brings it to that goddamn fucking mouth and let's his tongue hang out, thumb gliding down it to lick up the sauce.

Something snaps in Zuko, his cock achingly hard again and all the noise in his head going silent. He's lost to his basic instincts, his desires, his body screaming and shouting to touch and to be touched.

There's a moment of stillness, Sokka's lips wrapped around his thumb and Zuko sitting with eyes wide and half eaten slice of pizza in hand. It's all in slow motion as Sokka pops his thumb out and the pizza slice finds it's way back into the box.

But as things feel slowed down, a battle of wills and desires and who will make the first move, it all comes crashing at full speed as Zuko finds himself straddling Sokka's lap and lips pressed against his. His hands cup around Sokka's jawline, Sokka's own grasping hard around his waist, greasy fingers making indents in his flesh.

"Fuck, fuck you, fuck this fucking mouth," Zuko manages to mutter out between sloppy kisses that taste like pepperoni and garlic, "fuck… can I fuck you?"

Sokka's hands have already pushed up Zuko's shirt over his back, the fabric bunching around his shoulders. Sokka is not one to waste time.

"I thought you'd never ask," Sokka responds, his hands snaking around front to give Zuko's pecs a squeeze before tugging the rest of his shirt over his head. "I thought I couldn't make it any more obvious that I've been wanting to jump your bones for months."

If Zuko was capable of rational thought in that moment, he would have probed into that, questioning whether he had been an idiot and oblivious this whole time. But Zuko was not a rational man capable of thinking beyond the desires of his body and heart.

He needs more, needs Sokka's hands on him, everywhere all over touching him in ways that makes him harder. They're all lips, tongues, clumsy and messy, teeth occasionally clashing against each other. Zuko break them apart momentarily only to kiss his way down Sokka's jaw and long his neck, nipping softly at his collarbone.

"Wait… wait, before we go on," Sokka says, pushing lightly at Zuko and bringing his face back up to meet his, "I ummm, I don't want my chest touched, not yet, and I call it a cunt or hole, oh cock, I like to call mine a cock."

Zuko tries to will enough power back into his brain to comprehend and nods, "got it, cock, cunt, no chest… Can I eat you out?"

"Oh? Big boy still hungry? Pizza wasn't enough?" Sokka says with a sly smile, "fuck though, yes, please."

Zuko rolls his eyes at Sokka's comment, nuzzling his face back into the crook of his neck and leaving little marks along his collarbone. One hand holds onto the soft side of Sokka's belly while the other skips his chest directly fumbling with getting past the top of his pants. His hand plunges down further once he's between fabric and skin, finding Sokka's cock with his fingers.

"Fuck, Zuko, yes," slips from that goddamn fucking mouth with moans sounding like the most beautiful sounds Zuko's ever heard. "Please."

Zuko's fingers dip further between the folds of his cunt, already wet and needing, Sokka's begging making his own cock harder than he's ever imagined it could be. He clamours out of Sokka's lap, his ass bumping into the coffee table that he pushes back to make room. It creaks, one of the legs sitting at a weird angle that threatens to snap. Zuko grabs Sokka by the hips, helping him shimmy forward on the chair while also tugging his pants down.

The sight of Sokka's legs spread wide open before him, his cunt on display dripping makes Zuko's mouth water. There are angels blowing trumpets in his head, his heart pounding in his chest like it'll break out of his rib cage. Zuko's fingers slide down his cock and over his folds, two fingers pausing so he can spread the lips apart. His own mouth hangs open as he's lost in the sight of it all.

"Earth to Zuko, babe, are you, ohhhh ohhh oh" Sokka begins to say, his words lost in a moan when Zuko leans forward and licks a stripe up Sokka and takes his cock between his lips. "oh babe, fuck."

A string of moans and exclamation of pleasure flow freely from that goddamn fucking mouth of his, Sokka's head leaning back against the chair and hands gripping the arm rest as Zuko make work between his legs. He feels his tongue flicking here and there, going broad at times to lick around his cock.

"Fuck, babe, are… oh fuck… are you spelling your name with fuck fuck, do that one again, with your tongue?" Sokka asks while he brings his hands to lace his fingers into Zuko's hair.

Zuko gives Sokka one broad lick before leaning back on his heels, his hand replacing his mouth as he teases him.

"You can tell? Sorry, I hope it's not stupid, I heard about it once and thought maybe…" Zuko stammers out, his cheeks flushed and face looking bashful.

Sokka tries to answer but the words get lost in his moan when Zuko slips a finger into his cunt. This man, he'll be the fucking death of him he swears. It's as if they switched places, the once teasing Sokka laying back melting into a puddle in Zuko's hands.

"No, it's hot as fuck, sweetheart," Sokka manages to get out through heavy breathes. "Do it again?"

Zuko smirks and leans back forward to etch his name into Sokka with his tongue, a second finger slipping into his hot wet cunt. His free hand makes its way from Sokka waist, down his thigh and sliding off so he can palm his own aching cock as he works Sokka closer and closer to the edge.

Curling his fingers inside Sokka sends him screaming as Zuko keeps the pace with his mouth on his cock. Sokka's thighs clamp around Zuko's head, his hands gripping his hair as wave after wave of electric pleasure comes crashing over him. His chest heaves up and down, his breath lost along with his head in the clouds.

Zuko leans back again on his heels once he manages to free his head, wiping his mouth with the back of his hand. Beauty lays before him, blissed out on the questionable chair. Sokka tries mumbling some words together, but they come out as a string of incoherent babble.

"What was that?" Zuko asks as he squeezes Sokka's knees.

Sokka lifts his head from the back of the chair, his usually sparkling sapphire replaced with dark and stormy blues.

"You. Me. Bedroom." Sokka manages to get out, "fuck me."

"I will in a minute," Zuko says, getting off his knees and stretching out the kink in his hip from sitting so long like that. "I was really that good?"

"You licked the life out of me. 10 out of 10, would do it again. Five stars."

Zuko helps Sokka to his feet and blushes, trying to figure out this feeling in his chest at Sokka's praise. His best friend came because of him, his legs wobbly, head loopy, a near fucked out mess because of him. He packs that a way for later and thinks about what a sight they might be. Two young men in their shabby (shabby chic as Sokka would call it) apartment, one pantless and breathing hard while the other missing a shirt half carries him to a bedroom.

The two men find themselves in Zuko's room, Sokka turns around in Zuko's arm to grab a hold of his biceps. He manages to catch Zuko by surprise, smacking their lips together as Sokka begins to rev the engines up again. Zuko wraps his arms around Sokka, pressing their bodies close together. His erection still hard and aching as it rubs against the fabric that keeps them apart.

Zuko slowly guides Sokka back to his bed, letting the man fall back onto the mattress. He grabs a hold of his waistband, shucking off his grey sweatpants and boxers off, his cock springing free. Sokka looks down at it with eyes as wide as they can go, the space between his legs growing wetter and pulsing with need. He climbs onto his knees on the bed, tossing his shirt off so all that remains is the sports bra with the folded bills still stuffed in there.

"Oh yeah, I forgot about that," Sokka says as he reaches a hand around the back of Zuko's neck, the other lacing his fingers around his weeping cock.

It takes a moment for Zuko to realize what Sokka was referring to, the sirens in his head going off screaming about the hand that's on his dick.

"You and your goddamn fucking mouth, that comment made me uh… I wasn't in here meditating earlier," Zuko finally managed to get out once his brain caught up with what Sokka said.

Sokka gives Zuko's cock a few strokes after swirling his thumb around the top, smirking, "oh babe, sweetheart, I know, I could hear you, the walls are pretty paper thin. What was it you had said, 'fuck Sokka, fuck his mouth'?"

He learns further in by Zuko's hearing ear and nips as it lightly before whispering, "well, why don't you, Big Boy?"

For a second time that evening, that goddamn fucking mouth makes something snap in Zuko as he finds himself pushing the younger man down on the mattress. He climbs onto the bed, finding a space between Sokka's legs that feels like home, like this space was meant for him. Rutting hips against hips, his cock rubbing against Sokka's as lips and tongues find themselves messy and sloppy. Zuko begins to move down Sokka's jaw and neck, this time on the unmarked side, nipping, biting, soothing with his tongue. He'll mark him up and down his neck and collarbones, little memories of their evening together.

"Fuck babe, get inside me already," Sokka begs, "I need, please… condom, you have condoms?"

Zuko licks at his latest hickey, trying to think whether he has any. He doesn't have visitors to his bed that often, the last was maybe 6 or 7 months ago when Jet was in town, so he doesn't usually keep a supply on hand.

Peeling his chest from Sokka's, he leans over towards his nightstand and throws up the drawer. Zuko rummages around the mess that he really ought to clean up and organize. He finds Jet's Zippo lighter, Haru's mustache balm, a sticky note with a drawing Sokka had given to him. Towards the back he finds a zip lock baggie with a couple of condoms and a leaflet from the local LGBT center. This must have been in there from earlier that summer when they went to the Pride parade. A fucking goodie bag.

Zuko grins as he pulls the baggie out and holds it up for Sokka to see.

"Ohh, wanna see something hot? I mean other than me, of course," Sokka asks, giving Zuko another wink.

Zuko isn't sure what could be hotter than this beautiful man naked beneath him, but he's curious and nods. Sokka pushes back a bit, getting Zuko to his knees as Sokka slides out slight from underneath him to a seat position. He takes the baggie from Zuko, fishing out one of the condoms. Ripping it open, he pops the condom out of the wrapper and slightly unrolls it before placing the tip of it between his lips.

Sokka shimmies forward, one hand holding the base of Zuko's cock while the other lines the condom on the top of the head. In one swift motion, Sokka pushes his mouth forward, lips stretching around his cock as he rolls the condom down his length. His tongue hot and flat against the underside causing Zuko to buckle his hips and sputters nonsense.

He would have come right then and there if it wasn't for the little ounce of strength he had keeping himself together.

Sokka pulls back, letting Zuko's dick fall out of his mouth with a pop. That goddamn fucking mouth.

"Hot wasn't it? It's a lot more fun with those flavored condoms," Sokka says, his hand letting go of the base to graze his balls.

"I will buy you any and every flavored condom you want if you do that again," Zuko sputters out.

"Ohh, I wonder if they make like a matcha flavor, so you know, it'll be tea-cock. Yeah? Get it? Tea-cock, peacock? But I guess I have a tea-cock, cause the T."

Zuko swiftly pushes Sokka down back against the mattress, his brain screaming with the need to fuck Sokka until he can't say stupid shit like this. He needs to be inside him, feel Sokka around his cock, hearing only moans and his names and not puns or teasings. Zuko finds his place again between Sokka's legs spread wide for him, his cock sliding up and down his wet cunt as smashes their lips together to shut him up.

Sokka spreads his thighs wide for Zuko, his lower legs wrapping around his waist to draw him in. Zuko doesn't spare another moment of teasing his hole, pushing in deliberately slow so he can feel the stretch around him, the hot warmth that encapsulates him, the moans that it draws out of Sokka.

It feels like nothing he's ever imagined before, it's better, mind-blowing, and when Zuko bottoms out, he pauses to rest his forehead against Sokka's. This is his best friend. This is his best friend in his bed with his cunt wrapped around his dick. It's beyond his brain's comprehension, all he knows is that this feels amazing, other worldly, Zuko is on a whole other planet at pleasures and needs that rack his body.

"Go, please," Sokka weakly mumbles, his fingers digging into Zuko's back at just the feeling of being stretched out. "Zu…Zuko."

Zuko pulls his hips back and thrusts forward, setting a slow pace at first that makes Sokka's eyes flutter then snap shut. The thoughts fall out of Zuko's head, replaced the urges to quicken his pace and the awareness of all the feelings of bliss around his body. The way Sokka's fingers dig and scratch into his back, Sokka's moans that sounds like a siren's song to his ears, the way Sokka's legs tighten around his middle. The way that Sokka just feels all around him. He's drunk on the man he thrusts in and out of, lost in how his nose scrunches up as he moans, the hickies that mix with freckles that dot his neck and shoulders, how beautiful his face looks right now.

And all because he's doing this to Sokka. Those are his hickies that he marked all over him, his name that spills out of that goddamn fucking mouth, his dick and hands and mouth giving Sokka this fucked out blissfull look.

Zuko adjusts Sokka's legs so they're thrown over his shoulder, angling the man below him up so he can thrust in deeper. Sokka moans out louder, even more when Zuko rubs his cock in circles. The pressure builds up in his soft belly threatening to plunge over the edge and the twinges of electricity shoot up his back.

"Zu.. zu… I'm gonna… fuck, I'm gonna come," Sokka moans, hands clenching at the pillow beneath his head.

Keeping at pace, Zuko fucks Sokka over the edge, watching as he throws his head back and thrashes as he continues his pace. The filth that comes out of that goddamn fucking mouth of his pushes him over, spilling into the condom with a few final thrusts before it becomes too much for either one of them.

Sokka's legs slip off of Zuko's shoulders, landing ungracefully on the bed. He makes a soft noise as Zuko gently pulls out of him, emptiness replaces where he had been stretched out. Zuko manages to have enough function left to take the condom off, tying it up before he tosses it over to the wastebin by the door. Though he misses.

Zuko flops down on top of Sokka, both men breathless, sweaty, sticky and riding out their highs. Sokka nudges Zuko a bit, the weight on him a bit too much for him to get his breath back. The older of the two rolls off onto his side, his back resting against the coolness of the wall. Zuko brings a hand up to push back the sweat drenches hair plastering Sokka's forehead, his heart enamoured by this beauty before him. He's what those old masters would have painted in their grand pieces of art, his skin glowing, the folds of his belly soft and leaving Zuko wanting to touch.

Sokka peaks an eye open to see Zuko looking at him with a look he's rarely seen, but a look that makes his heart skip a beat. He turns into his side, grabbing Zuko's hand and bringing it to his waist. He entangles their limbs, pressing their bodies together until Sokka doesn't know where he ends and Zuko begins.

"Do you wanna go get boba? I think I need some balls in my mouth," Sokka asks as he nuzzles his face in the crook of Zuko's neck, laughing as the rumbling he feels in Zuko's chest as he groans. That goddamn fucking mouth.
