Of all people, it was Naruto who was affected first.
Sakura had assumed, like everyone else, that Kyuubi’s regeneration would heal Naruto of pretty much anything; proven by Sasuke’s chidori through his chest and poison on blades and wounds meant to kill mortal men. Naruto had survived everything without even the faintest scar and behind closed doors (and while very very drunk) Tsunade and Sakura had mused more than once what it would take to kill someone who healed from every wound.
They’d never considered that Kyuubi’s regeneration ability might exacerbate something instead of getting rid of it.
So it came as a bit of a shock that it was Naruto who showed signs of the poisoning first. But it also acted as a good warning sign to Sakura.
“Is it getting hotter out?” Naruto asked them as he tugged at the collar of his shirt, coat already splayed across the back of his seat.
“It’s not,” Sai said looking rather blandly amused, “Perhaps it’s the ten-steaming bowls of ramen you just inhaled?”
The ramen chef, some poor guy in this backwater little town, was staring at Naruto with something like awe and horror even as he prepared the eleventh bowl.
“Ramen does not betray me,” Naruto said solemnly, still tugging at his collar, “It’s just stupid hot out.”
“It’s summer,” Sasuke said flatly, “River Country is always hot in the summer.”
Naruto stuck his tongue out at him. Sakura eyed Naruto sideways, looking at the sweat beading on his forehead, and exchanged a glance with Kakashi. Kakashi gave her a deferential shrug.
“You didn’t touch anything in the base, did you?” Sakura asked Naruto suspiciously.
“No!” Naruto whined, “I’m not a little kid.”
They all side-eyed him and he whined again before turning back to the ramen. Sakura ran over what could have done this. They had been scouting an old abandoned base of Orochimaru’s that some poor village kids had run across. The hidden base and all it’s hidden skeletons. Anything of Orochimaru’s had long since been delegated as high A-rank or even S-rank in missions and Team Seven had jumped on board to go check out the old base that even Sasuke hadn’t been informed about in his time with Orochimaru.
Also the fact that they rarely all got sent out on missions together these days had made them jump to it. Something about all of them being on a team and sent out being ‘overkill’ and ‘overly threatening’.
They made a good team, Sakura though idly, they were just too good of a team what with all of them being stupid powerful.
Kakashi was being considered for Kage with Tsunade’s looming retirement, Naruto would be next in line obviously, but there were a few on the Council who had tried to push Sakura’s name forward what with having better habits than perpetual late porn-reading Kakashi and overexcited loud Naruto who avoided paperwork in a way that made Kakashi proud. Sasuke could have been a candidate for his strength if not for the whole, you know, betraying Konoha and trying to destroy it at one point thing. And Everyone knew Sai was being trained as an ANBU commander now that he wasn’t the creepy emotionless murder kid he had been before Team Seven.
And of course Sakura, apprentice to Tsunade in strength, medical jutsu, and running a village was of course a prime subject; the fact she could be polite and formal while running a hospital and the office was a plus. If Sakura had had dreams of Kageship she would have had no problem running for the office. But she’d been working under Tsunade in the office for long enough that she would gladly leave it to Naruto (the poor, poor fool).
All in all, Team Seven was called Team Overkill these days and they rarely got to go out on missions together. So they had all jumped to go do something like explore on of Orochimaru’s old bases.
Orochimaru had been as tricky as he was crazy though and his old bases were a death field for the unprepared. Sakura trusted Naruto hadn’t touched anything he wasn’t supposed to, but she wouldn’t have put it past Orochimaru to have had something silent, deadly, and airborne floating about in that dusty hole. Even slow acting poisons had various side affects she would recognize instantly though, and anything strong enough would have been obvious to at least one of her senses. So unless Naruto was picking up the flu (which, considering he never even got sick, was not likely), it must be something from the base.
Sakura leaned over, pretending to ask Kakashi something and rested a hand on the back of Naruto’s neck. He was hot. Really hot. No wonder he was sweating. Sakura’s mouth moved automatically in conversation even as she analyzed Naruto. He glanced at her and said something and she noticed the way his pupil was blown wide, the way his tongue kept darting out to lick his lip, the way there was a faint flush to his cheeks.
She knew something was really up when Naruto left his thirteenth bowl of ramen unfinished.
“Hey, can I talk to you a second?” he asked nonchalantly.
Sakura glanced at the team calmly. Sasuke was absent-mindedly shucking his cloak off and Sai had loosened his top, both seemed faintly distracted as they focused on their food. Kakashi’s book was gone as he watched her and Naruto openly. Sakura ran her tongue across her teeth and realized she was rather warm.
“Yeah,” she agreed standing.
They slipped out with a faint glance from Sai and Sasuke but no questioning looks. The retreated to a small alley and Naruto leaned against the cool shaded brick still tugging at his collar.
“Somethings wrong,” Naruto said matter-of-factly.
“Yeah,” Sakura said, distracted by the line of his throat.
Naruto had nice skin she realized inanely; skin kissed and perfectly tan. She wished she could get a tan that perfectly golden.
“I tried to ask Kurama what was up, if it was poison or something. He just laughed at me,” Naruto said, eyes a little lower than her face, “He’s still laughing. I’m kinda disturbed.”
“Hmm,” Sakura said thoughtfully, shifting in place as she realized her clothes were rather tight, clinging to her skin.
Naruto’s clothes were not tight and yet they still draped quite nicely across his body, and-
“Oh fuck,” Sakura breathed.
“Hmm?” Naruto asked, eyes half lidded, pupil blown wide.
His tongue darted out again and Sakura stared in a sort of fascinated horror.
“Are you aroused?” she asked faintly, “Cause I am.”
He stared at her for a long moment and then his hand slid down from his collar, following the lines of his body and Sakura couldn’t look away.
“Yeah,” Naruto groaned.
“We’ve been sex-pollened,” Sakura breathed, “Motherfucker."
“You know what, Orochimaru seems like the kind of guy to keep something like that,” Naruto said.
“Aphrodisiacs, concentrated in the air,” Sakura said, “Not a real poison so it didn’t set any of my triggers off, but something…”
“Kurama says,” Naruto said, cocking his head as his gaze went unfocused, “Says it’s mimicking a heat. For foxes I mean.”
“Shit,” Sakura said and realized her eyes were still on Naruto’s mouth, “Okay, we need a plan. I won’t be able to discover how to fight this before it kicks in. It already has I think and if it gets worse, I’m going to be too far gone to think straight.”
Someone walked past the alley laughing and they both looked over with a laser focus. A pretty civilian man was laughing with a woman, his head tossed back and his throat arching beautifully. Sakura resisted the urge to step forward and run her tongue up it.
“Shit. We’re going to be a danger,” Sakura swallowed, “We’re surrounded by civilians and if this is potent enough to get to a stage where we are rather mindlessly focused on sex…”
“Fuck,” Naruto agreed.
And then he moaned, panting harshly and shuddering as if something like heat had went straight up his spine. Sakura ran her tongue across her teeth and resisted the urge to slam Naruto into the alley wall with all her might.
“You get Sai and Sasuke, I’ll get Kakashi. We need to get clear of the town.”
“Sasuke and Sai,” Naruto breathed, the sound utterly pornographic.
But his gaze sharpened at the mention of the two men, focused and intent and Sakura consider the image he must be thinking of.
“Gods, they’ll look so good together,” Sakura moaned, thighs rubbing together.
Naruto’s grin was unholy.
“You get Kakashi,” he agreed, “I’ll get Sai and Sasuke.”
They hurried back to the ramen stand and Sakura could see Naruto losing control almost visibly. His walk devolved into a stalk, his eyes sharpening like a predator’s even as they blew wide. Every person that passed them drew their eyes, but they were ninja with a goal. Besides, how could these soft civilians compare to Sasuke and Sai and Kakashi .
They found Sai and Sasuke sitting in the same seats but now Sai had his hands tangled in Sasuke’s hair and Sasuke was dragging his teeth across Sai’s collar.
“Of course, you two repressed idiots have no immunity,” Sakura laughed even as she took in her fill of the view.
She was holding herself back by sheer will, but of course Sai and Sasuke had no practice with that. Naruto made a low growl, harsh and wanting, and Sakura wondered at the control she hadn’t known he possessed. Naruto had been hit first so that meant somehow, he was getting hit harder and faster by whatever this was, and yet he was holding himself back.
Sai and Sasuke jolted at the noise Naruto made but they barely had time to turn and look at him before Naruto had grabbed them both and flashed Sakura a lustful look before executing a perfect hirashin.
“Son of a bitch,” Sakura blinked yellow flashes away, “I didn’t realize he’d mastered that enough for passengers.”
Sakura paused and it took her a long, heat filled moment full of fantasies of Naruto and Sasuke and Sai falling together (all blond hair and tan skinned framed by white and black, god it would be so pretty) before she realized Kakashi wasn’t here. She looked around the tiny ramen stand and looked out the door. Kakashi wasn’t stupid, he had known something was up, had deferred to her, and yet…and yet he hadn’t waited for an answer. Which meant he worked out was happening just as quick as her, but instead of wasting time talking to Naruto he had… fled.
Naruto and Sakura had immediately known what was going to happen and sought out their team. Kakashi must have realized the track this was on and immediately fled his team.
“Tch, Sensei,” Sakura grumbled, “We’re not kids anymore.”
She put her nose to the ground (metaphorically) and tightened her gloves. Arousal heated her veins and Sakura held back a moan as she focused her whole body on the thought of hunting Kakashi down and pining him to the ground. She pictured the feel of his body against hers, grinding against her as she pinned him down. He was such a pretty man and she’d never gotten a chance to explore that line of possibility before, but now it made her body sing. She felt her lips spread in a wide grin and then she was off hunting.
.--.
Sakura found Kakashi in a back alley with a pretty civilian man back up against the wall. The man, almost still a boy she thought as she took in his face, didn’t seem to put out by how Kakashi was bracketing him. He seemed quite receptive, and Sakura almost felt bad as she prowled in to break them up.
“Get lost kid,” Sakura said not unkindly as she locked eyes with Kakashi.
The civilian looked between them, took in Sakura’s outfit, her headband and her blades, and was smart enough to get lost. Albeit, he did look back a bit longingly at Kakashi. Most would with his mask down and his pretty face on view.
“Sakura,” Kakashi said, voice a tad lower than usual but remarkably calm.
Sakura’s blood sang with it and she resisted the urge to lunge.
“You’d end up hurting him,” Sakura said pragmatically, “One little slip and you’d break his pretty little bones. And if the haze gets worst you might not even care.”
He was watching her like a wolf, eyes glinting in the light and the hint of fang bared.
“Why run Kakashi?’ she cooed, “It can’t be our ages, seeing as that young thing must have been a bit younger than us. Twenty if I’m being generous.”
“It’s not your age,” Kakashi said flatly but there was something dangerous in his voice.
“Oh?” Sakura asked stepping closer.
They circled one another almost like a dance. Sakura stepped closer, he stepped to the side. They didn’t look away from each other’s eyes. Sakura was wet and warm and she wanted to pin him down right here and now and ride him until he cried. But she could see Kakashi was more wolf than he let on and she’d have to win that right even with their blood boiling.
“Then what is it?” Sakura cajoled, feeling half crazed with want, “Do you only like boys?”
She ran a hand up her side, nearly moaned at the soft sensation that caused, cupping her own breast and letting out a breathy sigh.
“If I touch you…” Kakashi growled, trailing off, eyes sharp on her hands.
“If you touch me?” she asked.
“If I touch you, I’ll never stop,” Kakashi said sharply.
Then he lunged. His kunai hit hers in a scream of metal and they were off. Quick sharp blows, quick sharp retaliations. Sakura ducked, threw a kick, and he went with it, rolling around the foot and springing away.
They danced. Dangerous and thrilled and with blood boiling. Sakura felt crazed as she let the grin stretch her face till it hurt. She’d never been more aroused in her life as she threw herself at her former sensei, steel meeting steel. They didn’t touch at all, every meeting was between metal as they burst into the streets and over the heads of startled civilians.
When they hit the tree line the fight really started. Sakura threw a tree at Kakashi and he threw it right back with a doton jutsu.
“Are you going to fight me until I wear you enough to pin you down?” Sakura screamed with glee.
A water jutsu crashed down on her, but she had turned her skin to stone and braced herself. She came up soaking and grinning, throwing spears of rock at Kakashi.
Kakashi growled at her, a snarl that revealed his sharp canines. God he had a pretty face under that mask.
“I’m going to rip your clothes right off,” Sakura told him, “Then I’m going to hold you down and ride you until you scream. You’ll beg and beg and beg.”
“Not if I get you on the ground first,” Kakashi snarled, hands going for her throat like claws, “We’ll see who will be begging with my mouth on your cunt”.”
“Try me!” Sakura laughed, dodging the blow and throwing her heel at his face.
.--.
“Why can’t you be normal?” Naruto complained as he shoved a splintered log out of the way.
“What is normal?” Kakashi said groggily, face buried in his arms.
“Well it’s not fighting to the death before fucking yourselves stupid,” Naruto declared.
Sakura gave him a flat look from beside Kakashi where she was petting his flank. He was a damn hypocrite because she knew he would do the exact same thing.
“Where are Sasuke and Sai?”
“A bit off,” Naruto nodded in a direction, “They’re dead to the world. I wore them out.”
He gave a wide proud grin and Sakura gave him a thumbs up, he gave her one right back, both of them glowering proudly.
“We heard the fight,” he told her, “and then Sai mentioned something about how some animals eat their mates after sex so he insisted I come make sure you hadn’t ripped Kakashi’s throat out.”
“Did he really?” Sakura brayed with laughter.
“He was concerned,” Naruto grinned, “Said he hadn’t read anything about death matches before sex.”
“Tell him to piss off,” Sakura laughed, “We’re just fucked up enough that a good spar gets the blood going.”
“Needed a bit more than sex pollen?” Naruto teased.
“Fuck off, Naruto,” Kakashi said.
Naruto laughed but indeed fuck off back to the other two.
“He just wanted to check on us,” Sakura said, running a hand across Kakashi’s side.
Kakashi rolled over and reached out to pull her close. She felt his cock growing hard between them and grinned.
“Not all tired out then?” she asked throwing a leg over his hip.
“I said once I started touching you I wouldn’t stop,” he said as he kissed her.
