"Fwaahhhh," exhaled Naruto as he slid into the hot spring water.
Domestic life came with very different stresses than all-out-war for the fate of the world, but it was still important to find time for relaxation. Quiet time in the onsen was a real luxury these days.
"Oi, Kiba! Shower before getting in the bath!" Shikamaru barked, irate.
Well, "quiet" was always a relative term around Naruto's preferred crowd…
He, Shikamaru, Kiba, and Choji had come together to hang out. It was rare for them to all have the same afternoon off, so they tried to make the most of it whenever they could. The old "back of the class crew" from their Academy days. The other three hadn't exactly been Naruto's "friends" back then so much as "the other slackers who'd sometimes slack off together with him". Times had really changed since then. The young men he was sharing the onsen with now weren't just the back-of-the-class crew any more, they were his chosen family. They meant the world to Naruto. He had gone on dates and hooked up with all of them multiple times in the years since returning to Konoha with Jiraiya (mostly starting in the rebuilding period after Pain's attack), but it took the war for him to realise just how much all four really meant to him.
Naruto's life had been hard. Every good thing in it had been hard won, at heavy cost. He'd watched a lot of loved ones die.
There was no space in his life for anyone's prudish opinions about who he should share his love with.
He loved Shikamaru. Shikamaru was his rock; a source of stability in a life that tended towards the chaotic far too often. He was someone Naruto always knew he could rely on to bring order and a clear head to any situation.
He also loved Kiba. Naruto was chaotic, and a lot of the time, the dog-boy seemed like the only one who really got that and could match Naruto's energy. He was also a wild fuck. It turned out that a demon-fox and a dog-boy together would get up to a lot of kinky fun.
And he loved Choji. He somehow had the ability to bring life to a room, while also thriving on serenity. He was flexible — he had some of Kiba's fire, but more often that not it warmed rather than burned. He didn't have Shikamaru's problem-solving mindset, but he never failed to make Naruto feel safe; like everything would be okay.
Each of his relationships was unique and special. Shikamaru and Choji were both relaxing presences, albeit in different ways. Choji and Kiba both had boundless energy in the bedroom. Shikamaru and Kiba…well, they were like oil and water, but they both loved Naruto deeply, though they expressed it in different ways.
Polyamory wasn't exactly common in Konoha, but Naruto couldn't have cared less. Who knows, maybe they'd start a trend?
Once upon a time, Naruto was also head-over-heels for both Sakura and Sasuke, but that had all gotten…messy. Things had calmed down a lot between them since the end of the war, but that road was a dead end anyway. Sasuke really seemed to be straight after all, and he and Sakura were strictly monogamous. Fair enough.
Kiba returned from the shower, naked and dripping wet. Shikamaru seemed like he might try to kick up more fuss, since the dog-boy had obviously just quickly rinsed himself down rather than washing properly. But, he held his tongue. Kiba seemed clean enough.
Naruto drank in the view unabashedly. A sultry smile danced across his face as he ogled Kiba. Scratches, bite marks, bruises; Kiba was proudly displaying all the marks Naruto had left on his body during last night's tryst. In the sheets, they were fox and dog; two wild animals always wrestling for dominance.
Naruto's eyes wandered across his lover's body. Kiba was very much a "show"-er. His cock measured just under 6" soft, and it was thick. Naruto loved feeling the weight of it in his hand. Kiba was uncut, but with a naturally short (albeit loose) foreskin. About half of his head was exposed at all times. When he popped a boner, he barely gained 1" of length (of course, that still left him at a very respectable 7"), but that was enough to make the foreskin comfortably retract and reveal his full glans.
And Kiba was ripped. He was even more of a gym rat than Naruto, and was a fair rival for him in terms of pure hand-to-hand combat (of course, that was a very different story when chakra was factored in). Kiba had broad shoulders, strong arms, swollen pecs, and thigh muscles that could split a log. He was rightly proud of his body. Whenever Kiba won their contests for dominance, he would always make Naruto worship his muscles with his tongue and massage oil.
But last night, Naruto had been the dominant one, and there was a very specific prize he had wanted to claim.
Naruto liked to focus on one body part at a time to ravish. Sometimes it would be Kiba's hole. Naruto loved to rim, fuck, and sometimes even fist Kiba until his sphincter was puffy and gaping. Other times it would be his balls — those nights were a real challenge for Kiba.
But last night, it was his nipples. Naruto had spent hours pinching, sucking, biting, and generally abusing Kiba's succulent tits. Oh, they were so good.
For Kiba, the nipple focus was an extra special treat — they were possibly his favourite part of himself.
Kiba fit the stereotype of the gay bodybuilder through and through. His body was an erotic sculpture, crafted to inspire as much male lust as possible. Every sex characteristic was emphasised and exaggerated.
And so, Kiba believed that a big set of pecs should be capped with a proportionally large pair of nipples. For him, that meant thick eraser-tip nubs sticking out nearly an inch from wide, puffy areolae. Kiba had worked just as hard for those nipples as he had for his pecs and the rest of his well-honed body. He had a nipple training routine that he'd been sticking to religiously for years, mostly comprised of using clamps and powerful suction cups on them. The effect had been slow to set in, but over time he had completely transformed his nipples into the obscenities they were now.
No man ended up with tits like Kiba's as the result of genetics alone. He was a kinky freak, and every time he went topless, it was like waving a flag that advertised that fact. The unnaturally meaty nipples probably also scared away those who didn't share his aesthetic, but scaring people off was never something that Kiba gave a shit about.
And right now, they were even more prominent than usual. Whenever they got a good enough working over (like the treatment he received from Naruto the night before), Kiba's tits would appear even thicker and puffier for a little while. The colour was affected too. Normally medium brown in colour, they currently had a reddish-pink tint in addition. The ends were even more strongly coloured — practically purple. All in all, they had picked up a certain "used and abused" look.
Choji let out a low whistle.
"Phew, Kiba's tits look fucked. You must've done a real number on 'em, Naruto."
"Oh, did I ever," smirked Naruto, not looking away from Kiba's muscular chest.
"I keep telling ya' Choji, you should try it some time," replied Kiba. "You've got loads to work with there, you could get those guys pumped up as big as you like in no time."
Instinctively, Naruto and Shikamaru exchanged a meaningful glance and braced for a fight. Though they knew that Kiba's word choice of "loads to work with" was referring to the fact that Choji had by far the widest and softest areolae in the group (albeit with inverted nipples that normally hid below the surface), there was an obvious way to misinterpret it as being about Choji's physical size. Choji hated being called fat, and was sensitive to allusions towards his heavyset build.
But, it seemed they needn't have worried. Choji either understood what Kiba meant, or didn't even notice the potential double-meaning. He really had come a long way — just a few years ago, teenage Choji would have punched Kiba across the room for being so careless with his language. And in fact, he had done exactly that many times over the years they had known each other. Either way, he took Kiba's comment in his stride.
"Hah, maybe we should set a date then," Choji teased. "Then you can show me exactly what you want to do to them."
Kiba looked like he was about to respond positively, but after flashing his teasing smile Choji cut in again. "And besides, your puppy brain is so incorrigible, you'd probably just keep hounding me until I said yes anyway."
Choji knew exactly what he was doing. He might have gotten his own short fuse under control in recent times, but Kiba was as easily provoked as ever.
With a snarl and a heavy splash of spring water, Kiba was on top of Choji in a flash, gripping the other ninja's nipples firmly between thumb and forefinger. He kneaded the soft flesh purposefully, pinching the tips of Choji's inverted nipples through the surrounding tissue. Kiba dug his fingers in hard, trying to get a hold behind the hidden tip in an attempt to coax it out into the open.
"Uwahhhh," Choji moaned. Kiba's touch was firm and expert, and it felt fantastic.
"Who's hounding who?" Kiba breathed. "Why set a date when we're ready to go right now?"
Choji could only moan again in response. The pleasured sounds raised the masts of everyone present.
After just a few seconds of Kiba's ministrations, Choji's inverted nipples popped out into the world. On account of Choji's nipples and areola being much wider and generally larger that most other guys', the tips were also a bit fatter and stuck out further than was typical. They didn't come close to the prominence of Kiba's bullet nips, but were about as chunky as Naruto's nubs. Which was impressive, given the growth that Naruto's nipples had experienced as a result of Kiba's frequent abuse. Where Choji's nipples really stood out from his friends' was in their pale pink colour; several shades lighter than either Naruto or Kiba. Their barely pigmented colouration added to their impression of softness and sensitivity.
Right now, Kiba was most interested in the fact that their suppleness meant they were very easy to keep a firm grip on while tugging and twisting.
Which he was doing. Hard.
Kiba was trying his hardest to rough him up, but Choji was a tough customer. He even found it enjoyable. He smirked at Kiba, as though to say, "is that all?"
Choji stood up, forcing Kiba into a standing position along with him. To keep his grip on Choji's nipples, of course he would have to follow. The result was both of their hard cocks becoming exposed to the other two. The hot water had coaxed their heavy balls into hanging low in their sacks; they swung obscenely as the pair scuffled. Both thoroughly enjoyed the exhibitionism, and both Naruto and Shikamaru enjoyed the private show.
Kiba tried harder, tried to force a reaction out of Choji, but he didn't budge. His resilience was hot as fuck. The more Kiba tried, the more he thought Choji may actually be a match for him. He needed that. He needed someone to go all out against. The thought made him unbelievably horny.
"Choji…do me too…" Kiba begged. He felt a burning emptiness; his thick nubs were missing something important — hands, mouths, teeth, clamps, anything. The intense treatment he was dishing out on Choji had left his own chest feeling neglected, and in that moment he'd have given anything to satiate that desire.
Choji smiled victoriously. Kiba was too easy. "Thought you'd never ask."
When Choji took Kiba's tits firmly between thumb and forefinger and twisted, Kiba's deep, lustful groans instantly jumped up an octave or two. "Aaaoohhh! Ohhh fuck!"
"Oh fuck….ohhhh fuck, you fucking asked for it…" he growled. Kiba had lost control only for a brief moment, but he was going make damn sure to return the favour to Choji tenfold.
It was on.
"Ha, this brings back memories," commented Naruto. It was somehow nostalgic, watching his two friends/lovers at war like this, wrenching on each others nipples until one finally cried surrender. "It's just like titty twisters back at the Academy."
"Come to think of it, wasn't it always Kiba starting it back then too?" said Shikamaru.
"Obviously it was him, he's been nipple-obsessed since forever," snarked Choji. It was true, as well. Nipple twisters were a prank that Kiba had been suspiciously fond of in their youth.
Although, it may not have been wise of Choji to kick the hornet's nest like that.
"Grr, you shut up!" Kiba clamped down even harder on him, squeezing with all his strength.
"Ahhhhhhh!"
"Hey Naruto," Shikamaru called, "get over here. I know you wanna get some action too."
Shikamaru underscored his proposition by miming a pinching motion with his fingers, making it clear what kind of "action" he intended (if it wasn't already obvious).
Naruto wasn't at all inclined to turn him down. Shikamaru preferred more gentle play than Choji or Kiba, and that was exactly what he was in the mood for right now. Something relaxing, to complement the soothing hot water of the bath. He waded over to where Shikamaru was sitting, and sat down nestled between his legs with his back turned. In that position, Shikamaru could reach around to grope and massage Naruto's chest from behind while they both watched Choji and Kiba's titty twister war.
Naruto's nips were more perky and had thicker tips than the average guy, mostly thanks to to Kiba's influence. They didn't get worked anywhere near as hard or as often as Kiba's tits, but dating a nipple fetishist comes with some guaranteed side-effects. They had started off a very pale pink like Choji's, but over time (in fact, exactly since he and Kiba got together) they had darkened a bit. Now they appeared as more of a dusky reddish-pink, closer to Kiba's.
Meanwhile, Shikamaru was unique in the group for having pierced nipples. This made them exquisitely sensitive, and always perky. Just brushing against them accidentally would send a shiver down Shikamaru's spine. The piercings were no joke, either — at 6ga, or about 4mm in diameter, they had some real heft. It had taken him a long time to stretch up to such a large gauge, but it had been worth it. Shikamaru loved the look of the heavy metal embedded in his skin.
With that said, he was happy to keep his own nips uninvolved in the festivities for now. Shikamaru's pierced nipples needed a gentler touch on account of their much higher sensitivity, and something told him that his other friends were too horny to mind their strength. But with Naruto, he might manage to unwind a bit.
The sometimes-hyperactive blonde had wildly fluctuating energy levels. Sometimes he could match Kiba's chaos, and other times (like now), he was happier with the kind of slow relaxation that Shikamaru enjoyed.
Shikamaru continued his massage, kneading Naruto's tense pectoral muscles. He skirted around the nipples, teasing the blonde by never giving the direct stimulation he craved.
"Uwahhhh…"
Naruto liked nipple play, and he often liked diving right into the action. But he was in a hot spring, relaxing after a hard week. The slow buildup was a nice change. He could feel all the stress he had been unknowingly carrying melt away.
Meanwhile, Kiba and Choji were beginning to tire themselves out. Kiba had the handicap of his tits being raw and sensitive after their extended torment at Naruto's hands, but he was much better acclimated to such rough treatment than Choji. In the end, despite his best efforts it was Choji who reached his limit first.
"Okay okay, I give up! You win," Choji yielded.
"Heh, never mess with the master."
Despite the "contest" being meaningless and impromptu, Kiba couldn't help but acting self-satisfied after winning. It made a funny juxtaposition against his appearance, which he was predictably unbothered by. Specifically, how his huge nipples looked even more ravaged than before, thanks to the intense workout they had just received. They were more swollen, more reddish-purple, and the skin surrounding his areola was all inflamed from the pain and strain. Hell, never mind unbothered, he was proud of how they looked!
Choji's chest was in a similar situation, although a bit less extreme. The nubs did look a bit swollen, and they weren't retracting to their usual inverted state. The areola colour hadn't changed much, but the surrounding skin was even more red with inflammation than Kiba's was.
The pair finally sat down in the hot water with a satisfied "fwuahhhh" from each. Shikamaru watched them with amusement, while Naruto was relaxing with his eyes closed. Kiba and Choji had been fun to watch, but as Naruto became more relaxed and Shikamaru finally began playing with his nipples themselves, he lost interest in the scene before him in favour of enjoying the sensations he was receiving. Shikamaru's ministrations remained slow and teasing, but the direct pinching and twisting of Naruto's nipples was sending the blonde into a horny reverie.
"Oho, you guys got started too, huh?"
"You two numbskulls did put on a good show at least," said Shikamaru. Naruto remained non-responsive, content to ignore the discussion and enjoy his nipple massage.
"Low-energy is fine," reassured Choji. He sat down next to Shikamaru and hugged him. "That was meant to be the plan today, anyway."
"Not my fault my tits are irresistible," Kiba half-joked as he was sitting down. He had joined on the other side of Shikamaru, sitting intimately close and draping his arm around the other ninja's shoulder. "Yours aren't bad either," he teased, flicking Shikamaru's pierced nub lightly.
"Kiba…."
Before Kiba could start any fights with Shikamaru, a new voice spoke up from the other side of the room.
"You know, you guys should really not cause such a commotion in a public bathhouse. Anyone could walk in."
Naruto and his boyfriends all whipped their heads around simultaneously, not having noticed the newcomer enter the bath.
"Shino?! How long have you been sitting there?"
Shino Aburame's face remained expressionless as ever. Even while naked and submerged shoulder-deep in an onsen, he had kept his trademarked sunglasses on.
"What are you talking about? I've been here the entire time."
"Y'know, you really do creep me out sometimes, Shino…"
