This is a Canon!AU where Sasuke came back to Konoha because I just want Team 7 to be together. Sasuke is still an angsty little shit. He just came back after he killed Itachi, and Madara Uchiha isn't a threat (as far as they know...).
Summary: "Sasuke took a deep breath and tried to ignore his own disturbing libido. Now was not the time. Not that it was ever the time to seduce Naruto, but it especially wasn't now." Naruto is bit by a snake, and Sasuke sucks out the venom... and maybe other things. Shameless PWP, SasuNaru, Canon!AU
Sasuke held back a yawn for the millionth time as he jumped from branch to branch. Movement in his peripheral assured him Naruto was keeping pace with him. He's not a mother hen or anything. His teammate is an idiot and needs constant supervision.
Naruto caught Sasuke's eye as he glanced over. Sasuke averted his eyes and willed Naruto to keep his mouth shut. He was too tired to hear Naruto's rambling that only recently stopped.
"See something you like?" yelled Naruto, dangerously loud for a ninja.
Sasuke waited a moment before answering. He was working on his anger management issues. He hated to admit it, but he does have a tendency to get carried away in his emotions.
"Naruto," Sasuke spoke slowly, "keep your voice down. I'm only checking to see if you're still staring at my back."
It was a low blow, even Sasuke had to admit. Naruto has always felt like he was chasing Sasuke. Little did Naruto know, it was actually the other way around.
Sasuke was surprised when Naruto didn't immediately respond. He wasn't going to show weakness and look back though, not again.
"You're a bastard, you know that?" Naruto grumbled.
Sasuke did know. He also knew he was meanest to Naruto, another problem he was working on. It's not like Sasuke can tell Naruto that though. Naruto would tease him relentlessly, and his damn Uchiha pride couldn't take it.
They followed their old squad leader Kakashi in silence after that. Everyone was too tired from their mission to hold any conversations.
Kakashi didn't always come on missions with them, but Sakura was too busy working in medical with Tsunade. Naruto and Sasuke were back on the same team, but nobody trusted them to go on a mission by themselves. They had too much unresolved history as far as the village was concerned.
Their current mission was a touchy subject, and Sasuke was surprised their team was assigned to do it. It was to investigate an old lab likely left behind by Orochimaru.
Kakashi probably held himself accountable for Sasuke's defection to train with Orochimaru. They never talked about it, but Kakashi often talked to Sasuke without meeting his eyes. Sasuke thought his relationship with Naruto had suffered the most, but Naruto has actually been his anchor since his return.
The mission was fruitless. The suspected lab was destroyed; residuals of explosives and charred land were the only evidence of anything suspicious. It was so much travel for nothing.
Kakashi started to slow down, and Sasuke quickly matched his change in pace. Naruto ran past them, slow to react as usual.
"We're making camp over here. No complaining," Kakashi announced as Naruto groaned. If it were up to Naruto, they'd run back to Konoha without any breaks. His stamina was endless.
It was a good place to set up camp. They were close enough to Konoha that they could have a campfire without fear of discovery, and there was enough space for everyone to spread out. Naruto and Sasuke went to collect wood, while Kakashi set up the bedrolls and divvied up the food.
They ventured out into trees to find any dry wood despite the recent rain. Sasuke would rather work in silence, but he knew Naruto couldn't bear it. Sure enough, Naruto started blabbing on about nonsense by Sasuke's third stick. At least Naruto's incessant chatter distracted him from his own thoughts.
"...right, Sasuke?" Naruto asked, looking expectantly at him.
Sasuke hummed a noncommittal response, hoping it would satisfy him. Naruto nodded excitedly and continued talking. Everything was going well until he noticed Naruto had only one stick. He tried to leave it alone, but his patience was wearing thin after their long day.
"Idiot," Sasuke addressed Naruto impatiently, "how are you this bad at collecting sticks?"
Naruto blinked and looked over at the pile of sticks in Sasuke's arms.
"You cheated!" he accused, his eyes narrowing at Sasuke.
Sasuke threw his hands up in exasperation, dropping the sticks.
"How could I cheat at this?" he asked.
Naruto grinned and raced forward, shoving Sasuke to the ground as he grabbed at the fallen sticks.
"Like this," he replied smugly.
Sasuke narrowed his eyes. He could feel his sharingan activating, an involuntary response when he was annoyed. Naruto was challenging him to another stupid game, and he was rising to the bait. He didn't understand how Naruto could get under his skin like this. He never cared enough to acknowledge anyone else's annoying actions, but Naruto always knew how to get a response.
"See, now you're paying attention," Naruto started as he knelt down to pick up more fallen sticks, "I was trying to have a real heart-to-heart, you know, but you had that constipated look on your face when you- ow!" Naruto screamed, breaking out of his rant.
Sasuke saw a glimpse of movement, his sharingan honing onto a snake attached to Naruto's left inner thigh. Naruto dropped the few sticks he had proudly stolen as he registered what was happening. He froze with his hands out, a look of dumb terror on his face.
Sasuke rolled his eyes and leaned over to grab the snake. He carefully grabbed the snake by its head, putting pressure between the eyes and soft underside of its head to open its mouth and keep it from striking again.
The fangs slid out of Naruto's thigh. Sasuke observed the snake, ignoring Naruto's dramatic noises. When Naruto was truly injured, he pretended he was fine, so Sasuke ignored him for the moment.
That is until Sasuke realized what kind of snake he was holding. The snake was a deep purple, its head triangular with long, pointed fangs. Sasuke recognized the snake from Orochimaru's hideout. Its venom was deadly.
Sasuke looked from the snake to the wound. A little blood was soaking through the tiny holes in Naruto's jumpsuit. Sasuke knew he had to act quickly.
"Take off your clothes," Sasuke commanded, finally looking up at Naruto. Naruto's face was pale and sweaty. It's because he's panicking, Sasuke told himself. He's not dying.
This would normally mean death for Naruto, but Sasuke knew the Nine-Tails would keep Naruto from dying. Probably. He had to take countermeasures just in case.
Naruto stopped staring at the snake to glance at Sasuke, but his eyes kept flitting back to the snake.
"What? My clothes?" Naruto asked. He sounded disoriented, his speech already slurred by the venom's effects. This would get very complicated if Naruto fainted.
Sasuke stood up. In one fluid motion, Sasuke unsheathed his katana and sliced the snake in half. He felt a moment of guilt, but he was too worried about Naruto to dwell on it. He threw both halves of the snake far into the trees and sheathed his katana, comforted by the familiarity of its hold.
He turned back to Naruto. His blue eyes were glazed, his forehead beading with sweat. He was staring at Sasuke desperately. Sasuke paused for a moment, Naruto's look catching him off guard. Naruto looked... erotic.
Sasuke took a deep breath and tried to ignore his own disturbing libido. Now was not the time. Not that it was ever the time to seduce Naruto, but it especially wasn't now.
He knelt down facing Naruto and reached behind him for the zipper of his jumpsuit. Just as he started pulling the zipper down Naruto's back, Naruto's head leaned into Sasuke's shoulder.
"Sasuke," Naruto groaned softly. His breath was shallow, warmth spreading through Sasuke's shirt onto the skin of his shoulder. Sasuke braced his free hand against Naruto's shoulder and forced himself to keep pulling the zipper down. He tried not to think about the fact that he was undressing Naruto.
Once Sasuke unzipped Naruto's annoyingly orange jumpsuit, he cushioned Naruto's head with his hand as he laid Naruto onto the forest floor. Sasuke brushed Naruto's sweaty blonde hair away from his forehead and watched in fascination as Naruto pushed his head into Sasuke's hand. His eyes were barely open, still gazing up at him.
Sasuke swallowed and braced himself to strip Naruto. This was going to take a lot of willpower, something Sasuke did not usually have.
He pulled the jumpsuit over Naruto's shoulders and down his body, his fingers brushing against hot skin. Finally, Sasuke pulled Naruto's jumpsuit over his shoes and threw it off to the side.
He took a selfish moment to look at Naruto's body. Sasuke had seen Naruto naked plenty of times. They had to camp out and even bathe in the forest for some missions. Sasuke had never allowed himself to admire it though.
Naruto's body was tan and impressively toned, lean muscle curving over his arms and across his stomach, a small trail of blonde hair leading from the swirl of his black seal to the waistband of his boxers. Then, Sasuke eyed the embarrassing design of frogs on his boxers and remembered what he was supposed to be doing.
It was time to suck out the venom.
Sasuke wasn't sure how well this would work. Naruto was already being affected by the venom, which meant some of it had spread. He just didn't know what else to do.
Chastising himself for wasting time on his stupid crush, he curled his hands under Naruto's knees and lifted them up. He swallowed. Naruto was spread out and panting underneath him.
He imagined himself leaning in and slowly, gently brushing his lips against Naruto's. As Naruto gasped, Sasuke would catch his lower lip between his teeth and nibble the sensitive, pink skin teasingly. He would mouth along his chin and then down his jaw with light flicks of his tongue, driving Naruto crazy. He would grab Naruto's wrists and hold them above his head. Sasuke wanted complete control. Naruto would strain against him, refusing to be dominated, but Sasuke would show Naruto the pleasure of being completely consumed.
At this point, Sasuke was panting with Naruto. He decided that this must be karma. His imagination continued to play out this sexual fantasy as Sasuke leaned toward the two puncture wounds on Naruto's inner thigh. The skin looked so soft and sensitive.
Sasuke pulled Naruto's right leg over his shoulder and lifted his injured left leg higher. Sasuke's right hand slid along Naruto's uninjured thigh, the fabric of his boxers brushing against his knuckles. He leaned down and licked the blood from Naruto's wound, the metallic and salty taste of Naruto's blood filling his mouth. Naruto gasped.
Sasuke closed his lips around the puncture wounds carefully, the tenuous thread of his willpower wearing thin, and sucked. Hot blood bitter with venom filled his mouth, and Naruto's legs started squirming. Sasuke tightened his grip under Naruto's knee to keep him still.
He lifted his head from Naruto's thigh to spit out the poison and then leaned in for more. Sasuke would be lying if he said he wasn't trying to leave a bruise. He wanted to mark Naruto to remind him that they were this intimately close. It was only fair.
He kept sucking and spitting as Naruto's blood lost its bitter, numbing taste. Admittedly, it was hard to tell as Sasuke's mouth began to numb from the venom. Naruto was now moving with his whole body, presumably to get away from Sasuke's ruthless attack on his thigh.
Sasuke loved it. He didn't want to stop this torturous foreplay, now hopelessly aroused, but he knew most of the venom in that area was gone. He unlatched his wet, swollen lips and raised his head, eyeing the wound. It was clean of blood, shining wet and flushed pink against his tan skin. Sasuke hesitantly looked up to see if Naruto was conscious.
He froze at the sight. Naruto was gasping, supporting himself on his elbows, and looking down at Sasuke with hooded eyes. Thin trails of sweat ran down his neck over his chest. His erection was visible through his boxers.
"Sasuke," Naruto gasped, this time more desperate than dazed.
Sasuke closed his eyes for a moment and opened them again to make sure he wasn't hallucinating. Was he being affected by the venom? Naruto couldn't be as turned on by this as he was.
Sasuke slid the hand under Naruto's boxers higher and gently stroked his thumb against Naruto's inner thigh. Naruto closed his eyes and moaned. Sasuke leaned down and started sucking a new spot above his wound. He slowly trailed his mouth higher, Naruto's boxers scrunching up as Sasuke grew bolder.
"What do you want Naruto?" Sasuke asked breathlessly as he lifted his head again. His voice was so low and quiet, but Naruto picked up every word. Naruto reached his hand down and threaded his fingers through Sasuke's thick hair. His fingernails scraped gently against his scalp, and Sasuke's eyes drifted shut at the slow movement of Naruto's hands.
Then, Naruto gripped Sasuke's hair hard. Sasuke felt his hair pull and moaned at the rough feeling. Confused by his own reaction, he didn't fight Naruto's tight grip.
Naruto pulled tighter until Sasuke looked up at him. He felt hypnotized by his unwavering gaze. Since when was Naruto in control?
"Shut up and suck me," Naruto said simply. His tone was so forceful, so different from his usual carefree demeanor, and Sasuke realized how much he wanted Naruto to dominate him. He must be fucked in the head.
"Yes, sir," Sasuke replied. He meant to sound sarcastic or maybe defiant, but his weak voice only sounded obedient, reverent to his master. His master, Naruto. Dear God.
Still, his pride wasn't going to ruin this moment. He slid his fingers into the waistband of Naruto's boxers and tugged. Naruto lifted his hips off the ground so that Sasuke could finish undressing him.
Sasuke sat back on his heels and ran his eyes over Naruto's naked body. Only this time, he felt no shame because Naruto was watching him too. He was relieved to see Naruto's face was now flushed with color and his eyes were alert. The venom wasn't a concern anymore.
Sasuke didn't know he was holding back until he realized Naruto was going to be fine. All of his tension lifted as arousal completely took over. He could focus on his new mission now.
Sasuke smiled sweetly at Naruto, a smile Naruto found unnerving. He leaned in, like a snake eyeing its prey, to properly suck Naruto's cock.
Meanwhile...
Kakashi snacked on his granola bar as he leaned against a tree. Naruto and Sasuke never got anything done when they were alone together. He wondered if he should build the fire himself.
Naruto's scream suddenly echoed through the trees.
Shit. Kakashi lifted his mask over his mouth quickly as he activated his sharingan. He moved quietly through the trees toward Naruto's scream. He grabbed his kunai from the pouch around his thigh.
As he rounded another tree, Kakashi spotted Naruto and Sasuke on the ground. He started to run toward them until he realized that Sasuke's head was between Naruto's legs.
Kakashi was no stranger to fooling around, but he wasn't sure what he was looking at. Sasuke was making out with... Naruto's thigh? It looked odd and a little excessive for foreplay, but Kakashi shouldn't be seeing this anyway.
He returned to their campsite as quietly as possible, smiling under his mask. Sasuke finally found some positive motivation.
This is the first finished fanfiction that I've published. Honestly, I just love the 'suck the venom/poison' trope, and I was annoyed that I couldn't find a good one for NaruSasu. Now we have one. :)
