Sai was staring at him again. Naruto could feel his eyes on his back as he shucked
his clothes.

“Quit it, Sai.”

“I’m not doing anything,” came the highly amused
reply.

Naruto huffed as he dropped his clothes into the basket and grabbed a towel.
“You’re staring at me.”

“Is that wrong?”

Naruto wrapped the towel around his privates before he turned around to glare at
Sai, who was already lounging in the men’s side of the hot spring. “It’s creepy.”

“But not wrong,” Sai insisted with that same lifeless smile he always
wore. “It’s in the book I read.”

“Look,” Naruto said as he stepped past Sai and deeper into the water,
submerging himself until the water lapped against his golden-tanned shoulders, “I don’t care what those stupid books tell you, stop looking at me like that.”

“Like what?” Sai inquired.

Naruto wouldn’t have bothered to answer if Sai hadn’t sounded so
Kami-damned honest. He settled on the far side of the spring—the only place he was willing to be when he had this sort of conversation with a now shrouded and misty-outline of
Sai—before he answered.

“Like you’re raping me with your eyes.” Naruto dunked his head
and straightened just as quickly. He shook his head, throwing a shower of water that marked a half-circle around his position against a large rock he rested his back against.

Sai was silent for a moment before he said, “Ah. I understand
Naruto.”

“You do?” Naruto said, relieved that this wasn’t going to be a
drawn-out conversation about Sai’s awkward social etiquette. Those never ended well.

“I do. The book mentioned something about this as well.” Sai’s
outline became larger and a moment later he appeared out of the foggy heat. “I shall endeavour to be more sensitive to your concerns. It’s what friends do, after
all.”

“Thanks,” Naruto said, eyeing him warily. Bad things always happened
when Sai started talking about “friends”.

“Indeed, I hadn’t realized you were ashamed to show your penis in
public.” Naruto froze as Sai’s smile widened. “The book also mentioned these sorts of complexes are usually the result of an episode in early childhood. Did you have a bad
experience in the public baths as a boy; perhaps the other boys made fun of the size of your penis, and you have since become highly aware of your own inadequacies compared to your other male
peers?”

“Sai…” Naruto growled. He flexed his hands underwater, imagining
them wrapped around his pale neck.

“Perhaps this is also the source of your rivalry with Sasuke? Not only is he
stronger than you, but his dick is bigger too?”

“That is IT!” Naruto snapped. He stood, exposing his chest and pointed
accusingly at Sai. “It’s always penis-this, penis-that with you! I’m fucking sick of it! Why don’t you put up or shut up?”

“Put up or shut up?” Sai tilted his head curiously. “I’m
afraid I’m not familiar with that expression.”

“I’m saying,” Naruto said slowly for his benefit, “that if
you want to fucking keep insinuating I’ve got a small dick, you better have something bigger between your own fucking legs.”

“I understand,” said Sai solemnly, his face losing its
smile.

“F-fine. Then…” Naruto was a bit at a loss as how exactly they
were going to proceed. Ideas always sounded better in his head until he said them out-loud.

“One moment Naruto,” Sai said, holding up a hand. “While I
understand and sympathize with your determination to settle who has the bigger penis, I have no reason to play along.”

“Huh?”

“I’m saying,” said Sai in a manner that mimicked Naruto’s
earlier patronizing tone, “that unless we make this a bet with forfeits, I have no reason to humour you.”

Naruto’s forehead wrinkled as he lost a bit of his steam.
“Forfeits?”

“Indeed. For instance, should your penis prove larger, your forfeit shall be
that I shall no longer be able to call you a dickless runt. That’s your condition, correct?”

“I guess.”

“Good.” Sai still wasn’t smiling. It was possibly even creepier
than when he was smiling. “Then to satisfy your curiosity you won’t mind if the loser gives the winner a blowjob…will you?”

“What?” Naruto sat abruptly again.
“Gross!”

“Well, no-one’s forcing you. We can always just call the whole
thing off.” Naruto had started nodding furiously when Sai continued in his uncaring as ever voice. “Of course…that would mean you’re not too confident about your chances
of winning.”

Naruto sputtered for a second, red in the face, until he regained his wits.
“You win either way! And if I win…I still lose!”

Sai blinked then frowned. “You consider getting a free blowjob as
losing?” He seemed honestly baffled.

“I’m not into that sort of thing!” Naruto hissed at
him.

Sai shrugged. “You’ve never gotten a blowjob from an ugly bint before?
Just close your eyes. You can’t tell the difference. Unless—you’ve never had a blowjob before?”

Naruto glared at Sai and tried to will away the deluge of images and sounds his
comment recalled to his mind’s eye; bloated painted lips, pink fingernails, whispers of sweet nothing, filthy smell of sweat and urine, rough calloused fingers, assuring coos muttered
cruelly into his ear.

“I have,” Naruto managed a moment after swallowing the
unpleasant acidic sensation that was trying to migrate up his throat. When Sai tilted his head curiously Naruto decided to elaborate. “Ero-Sennin thought it would be a great idea on my
sixteenth to get me roaring drunk and then buy a prostitute to keep me occupied for the evening.”

“Was she ugly?”

“No.”

“Then she bit your dick or something?” Sai asked.

“No!” Naruto protested again.

“Then why do you seem to have some kind of aversion to a
blowjob?”

“I don’t have an aversion,” Naruto muttered and chose to
watch the small bonsai trees lining the bamboo wall separating the men and women’s baths instead of meeting Sai’s dark eyes. “You’re a guy. That’s all. It’s
nothing personal.”

Sai hummed to himself thoughtfully. “I always thought Eggplant was gross when
I first saw it cooked in a stir fry.”

Naruto couldn’t help but snap his head back at the abrupt segue into
nonsense. “What?”

“It smelled funny and got all brown and shrivelled. But I ate it in the end.
I forced it into my mouth because as a matter of fact I couldn’t honestly say it tasted nasty until I tried it. Turned out it was really good. It’s in our nature to learn by
experiencing—that’s what all the books I read keep telling me. I don’t think this is any different. It’s not like you’ve done anything with another guy, have
you?”

Naruto swallowed and licked his lips nervously, avoiding Sai’s eyes once
again. They reminded him too much of Sasuke’s sometimes.

“You have.” He was surprised, but not disbelieving.
“When?”

It would have been so easy to just tell him it was none of his business and leave
it at that. But when Naruto opened his mouth to tell him off he reconsidered. He took a short breath and began:

“You know I was off training with the Toad-sage Jiraiaya?” Sai
confirmed the statement with a nod. “Well…Jiraiya wasn’t just training me to get stronger…he was also training me in his mastery.”

“It is a little well-known fact that Jiraiya’s true mastery is not that
of sealing or ninjutsu, but rather his espionage and stealth abilities,” Sai confirmed. “While ROOT is aware of his talents, they remain mostly undocumented and are considered
somewhat legendary. You are very fortunate in that respect, to have such a talented teacher.”

“Yeah,” said Naruto bitterly. “Jiraiya’s method of teaching
isn’t like most teachers though. He prefers his students to fuck-up first, and then he explains what went wrong and suggests how to do it better. It sucks sometimes…but it works I
guess. He trained the Fourth, after all.

He took a deep breath, stalling to try and organize the tale in his mind.
“Late in the fall we ended up in a small dump of a town out west. Muddy streets, battered shacks for houses, whores with more fleas than the roving packs of dogs – it was the nastiest
place I’ve ever seen. The hamlet was being terrorized by a group of Ronin and their commander who had set up shop and decided to use the local population as their own personal slave-pen.
The provincial Magistrate didn’t have the troops to deal with the situation so he hired two roaming ninja to deal with the situation permanently. Jiraiya thought this would be a good
way to test what I’d learned from him so far. So he ordered me to infiltrate his troops and assassinate the commander and his lieutenants.

“While we were roaming around the countryside I had been studying how various
kinds of people acted and practicing imitating them—even ero-sennin has trouble picking me out of a crowd with I have my henge active. I thought this would be a perfect opportunity to use
that knowledge. The easiest way to infiltrate would have been a quick A.D.R. one of the lieutenants – uh…you know what that means, right?” Sai was ROOT. He should.

“Assassinate. Dispose. Replace.” Sai drudged the term from his memory.
“That technique isn’t considered effective if you can’t mimic a target’s mannerism effectively. There aren’t many ninja who have sufficient skill to do
that.”

“I could have if I’d had the chance. But they were always escorted by
no less than fifteen men. And when I say escorted, I mean everywhere. They even left the toilet stalls open while they crapped.” Naruto made a face. “I decided to replace one of the
male geisha whose only job up to that point had been to entertain the commander and his men with his poetry recitals and dance of the fans.

“What I hadn’t counted on,” said Naruto with great
self-deprecation, “was that the Commander had fallen desperately in love with the young man I was replacing. And apparently he had chosen the night of my infiltration to…consummate
his affections in front of his men.” Naruto’s laugh was ragged. “Ero-Sennin said to always plan for the worst when infiltrating. Looking back, I wish I’d taken his advice
a bit more seriously.”

Naruto slumped a bit, relieved that there was no pity or condescension lurking
behind Sai’s unwavering obsidian gaze.

“It was unpleasant?”

“Getting molested in front of a bunch of horny sociopaths? Yeah…you
could say that.”

“But you accomplished your mission?” Sai pressed.

“After he…finished…he took me back to his private room
to…go the rest of the distance. It’s strange. I always thought I’d have trouble killing a man in cold blood, you know? Someone I didn’t know that had to die just because
I had orders that condemned him. I thought I’d choke. But it was easy. I ripped his throat out before he could get any further and I enjoyed watching him drown in his own blood. I
was so juiced on Kyuubi’s chakra at that point I wasn’t thinking about anything else except to erase the filthy humiliation I’d just endured.” Naruto leaned back and
rubbed his eyes tiredly. “I then went one-by-one to each of his lieutenant’s rooms, seduced my way inside, and tore them to shreds until nothing recognizable was left. When I got to
the last one, him I left alive. He was so scared of me he pissed his pants, got on his knees and everything, kissed my blood-stained feet and wept for mercy. And so I told him he was commander
now, and if he didn’t want to end up disassembled like his friends, he’d disband his army, leave, and never return.

“I never told Jiraiya what happened,” Naruto continued absently. Water
flowed from his cupped hands and dribbled back into the pool. “Didn’t want him to think any less of me. I’d whored my way inside and got the job done. I felt like a monster. He
didn’t ask either. When I came back covered in blood he just nodded and told me “good job”. That was it. Started letting me do more solo missions after that too.

“The worst part…the worst part is…sometimes I can feel the
Kyūbi get excited. He got exited at the prospect of sex…and I got the feeling he liked the blood part even more. And when Kyūbi feels something very strongly…I have
trouble separating my own feelings and staying myself.”

“So…every time I’ve propositioned you before…that
was what you were thinking of,” said Sai thoughtfully.

“I said it wasn’t personal, didn’t I?” Naruto grouched
half-heartedly. “I just get the creeps thinking about that sort of stuff. It hurts. I have no idea why anyone would want to do that with another guy for
fun.”

“But you can at least admit that your perspective on the matter may be a
bit…skewed.”

“Maybe,” Naruto admitted grudgingly. “Doesn’t change how I
feel.”

“Maybe not.” Sai fell silent and was obviously deep in
thought.

Naruto shut his eyes, lost in his own thoughts as the heat and moisture lulled his
senses and loosened muscles tense from training. It wasn’t like he dwelled on the past. Sometimes something someone said or did would remind him—but never enough to disturb him. Sai
and his propositions however, seemed to bring out the worst of the memories.

“It’s a lot like rotten eggplant,” Sai said eventually, breaking
the comfortable silence. Naruto pried an eye open but said nothing. “What would have happened I wonder, if I’d chosen a rotten eggplant instead of a fresh one for my little taste
experiment?”

Naruto felt a smile tugging on his lips. “You’d probably avoid fried
eggplant like Kakashi avoids green-spandex and bowl-haircuts.”

“But if I’d told you the story about how bad fried eggplant tastes,
you’d probably want to correct me – or at least point out that maybe I’d cooked it wrong…or fried a bad batch.”

“Nah. I’d tell you to forget stir fry because it tastes way better in
some kinds of ramen,” he corrected.

Sai smiled this time; a real honest to Kami smile – eyes open and showing a
glimpse of bright-white teeth. “Then may I do the same for you?”

His face scrunched as he lost Sai’s train of thought.
“What?”

“You may not know this, but sexual relations between male shinobi are
actually quite common in Konoha; especially so in the Special Forces like ANBU where missions can last for months and the only people you can trust are members of your squad. And while it
isn’t advertized widely, having a sexual outlet actually improves mental stability in high-stress situations.” Sai ignored Naruto’s blank look of surprise and continued.
“You might remember my book and my friend in it? Growing up in the ROOT system, the bonds between two young males was fostered and common-practice because the resulting shinobi developed
faster and with greater mental fortitude than Shinobi without such bonds. I can get you copies of some of the studies performed in ROOT if it interests you.

“The point I’m trying to make is that many people find such things not
only beneficial, but pleasurable. It’s like anything else in life—sex can be wielded as a weapon, as punishment; just as easily as a reward, for pleasure. You’ve only
experienced one side of it. I’d be happy to show you the other if you’ll let me.”

Naruto squirmed uncomfortably under Sai’s earnest offer. “I don’t
know Sai—”

“Unless of course you’re afraid I’ll laugh at the size of your
penis, dickless.” Sai’s smile broke into a really freaky-looking leer.

“SAI!” Naruto yelled. His stomach lurched as Sai’s hands
slipped under the water, running down his chest to presumably fondle his—

Cheeks hot, Naruto forced himself to look away. If he hadn’t been thankful
for the obscuring steam before, he sure was now.

“The books I’ve been reading have all emphasized one particular
point.” Sai said, his voice hitching as his hand continued to work on himself. “They all say that the only way to become successful in life is to never give up. When the horse tosses
you from its back, the only way to keep moving forward is to get back on its back and try again. Unless you’re afraid.”

“I’m not afr – will you cut that out?” The water
disturbed by Sai’s ministrations was lapping at Naruto’s chest—preventing him from successfully ignoring what was going on a few feet from his position just under the surface of
the water.

Sai considered this for a moment, and then complied. He inched forward studying
Naruto’s face intensely. “May I touch you?” he asked, bluntly, irreverently, in the only way Sai ever seemed to speak during times where normal people would be
embarrassed…or at least properly modest.

“Sai—”

Naruto tensed as Sai’s hands, underwater, made contact with his knees, and
tugged on them gently, his dark eyes asking permission. Naruto licked his lips nervously. His eyes darted from Sai’s earnest arousal, which seemed doubly large and distorted by the water,
back to his face and associated smile.

Naruto was the smallest span away from telling him off. The simple act of Sai
touching his knees brought back the deluge of images and sounds that were not his most pleasant memories.

It’s just Sai, Naruto reminded himself sternly as he tried to blink half-remembered memories away. Why the fuck would I be afraid of Sai?

“-ruto? Naruto?” Sai repeated, his hands had meandered gently between
the small gap his thighs made. The towel he still had tied around his waist obscured the rest.

I can do this, Naruto told himself. He forced the steel wires his leg muscles had been imitating to relax; Sai’s hands did the rest. Sai moved closer, his
long-fingered hands gliding up and under his towel as he filled the now empty space between his legs.

The proximity of another warm and willing body sent blood shooting downwards. He
jerked and bit his lips to withhold curses as Sai’s hands finally reached their ultimate target and the spongy half-arousal was gently tugged to attention, tenting the small
towel.

“Hmm,” Sai hummed appreciatively. His gentle and firm touch wandering
up and down the shaft. His thumb fingered the head and slit, making Naruto choke out a semi whine-moan; his other hand slid over his balls and cupped them as if weighing them and sizing them up.
“For such a shrimp you have a disproportionately large set of hardware, Naru-chan. If girls knew about this they’d throw themselves at you. And fanboys would be begging you for five
minutes in a closet to worship you properly.”

Naruto swore loudly. “D-don’t call me that.” He wasn’t sure
when he had moved his hands, but his fingers were digging into the pale flesh around Sai’s collar-bone; his mind couldn’t decide if it was to push him away or keep him from moving
away. He could feel the hum of Kyūbi’s desire in the back of his mind—urging him to do all sorts of unspeakable and perverted things to the black-haired shinobi groping him.
“Dumb…pansy…name.”

Sai paused and tugged the towel free of the small knot holding it in place around
Naruto’s waist; hampered by the water his aroused cock sprang free, the painfully purple head clearing the surface of the water to rest against his flesh just above his belly-button.
Sai’s hands moved past the arousal in front of him and smoothed their way up his tense and ripped abdominal muscles until they came up and under his arms and cupped his neck, thumbs rubbed
his pulse points affectionately.

“Scared yet?” Sai asked. Naruto, through the burning haze of lust tried
to glare. He let his arms fall warily to Sai’s narrow, defined hips.

Control, his mind whispered. “What are you doing?”

“I’m going to make you feel good,” Sai decided with absolute
certainty. “But if you want me to stop, tell me. And I’ll stop. I promise I won’t do anything you don’t like. If you need to stop, we stop.” Naruto supposed Sai
thought he was sending him a reassuring smile, but in the position they were it came off more of a perverted leer.

Naruto’s tongue darted out to lick dry lips again as he contemplated what Sai
had planned; Sai’s eyes followed the motion with eyes of a hawk. Through his hands, Naruto felt Sai’s entire body pulse with a mix of arousal and restraint.

Sai released his neck, fingers lingering on his cheeks briefly. He guided
Naruto’s hands back up to his neck as he pressed closer. “It’s easier if you keep your hands here,” Sai explained as he manoeuvred his own hands into the water to latch
onto Naruto’s hips.

Sai’s entire body pressed forward until his own arousal made contact with
Naruto’s. Naruto kept his eyes from closing through sheer will, unable to look away from the slightly glazed look Sai’s eyes had suddenly taken on and the hiss of bliss that escaped
his lips. The pressure on his hips released as Sai slipped forward, friction setting off a jolt of pleasure, and his arms slipped up and wrapped them up from his lower back to clutch the rippling
muscles of his back, cradling him close until he was cheek to cheek, and Naruto had to wrap his own arms around Sai’s neck.

Sai’s breath was hot on his neck as he rocked his hips forward, grinding his
erection against his own. Naruto panted and wrapped his own legs up and around Sai, urging him down and pressing back up against the solid heat above him.

Sai’s motions turned frantic, his hips thrusting back and forth creating a
delicious friction that was sending a never ending pulse of pleasure from between Naruto’s legs up his spine. Naruto clutched harder panting almost in time to Sai’s harsh breathing.
All Naruto could smell was Sai’s scent—rich ink and something sweeter—nothing like the sour smell of BO and sake he’d come to associate with sex and men.

Their combined motions sent small waves crashing up around the rock Naruto was
half-resting against, spraying them both as their bodies writhed in pleasurable harmony arousals sliding together; hips pumping; soft grunts and moans. A keening sound was the only warning Naruto
had before Sai’s penis was jerking against his own as he came, Naruto gave in as he felt the unnatural warmth of his essence spattering against his flesh and released the impossible tension
in his groin with a loud incoherent roar.

He blacked out briefly, because when he came too Sai was nuzzling his neck with his
nose. Naruto tightened his arms feeling a bit lost and not wanting Sai to pull away to read anything into his expression.

“You should have taken that bet, Naru-chan. Although, if you beg nicely I
might consider it.” Sai’s lips pressed gently into his pulse point. “A big cock like yours deserves a bit of worship, neh?”

Naruto let out a shuddering breath and decided that didn’t deserve a response
when his cock was already hardening again in reflection of Sai’s own arousal.

The black-haired shinobi gently reached up and detached Naruto’s arms,
watching amused as said blond-haired man fell back against the rock without releasing his legs. Naruto squeezed his eyes closed and arched his back as Sai moved down his body, his mouth latching
on to a nipple and sucking hard. As Naruto let out an incoherent scream Sai wrapped his hands under his ass and shifted him up higher onto the sloping face of the rock, exposing his dick
to his wandering mouth.

Naruto couldn’t breathe at all when the hot moist heat of Sai’s mouth
and tongue teased his shaft and head briefly before Sai pried Naruto’s cock off his stomach and swallowed a good portion of it into his mouth and throat. He couldn’t help the blissful
moan of sweet agony that rumbled from his chest, nor the jerk of his hips as he tried to get more of that impossible warmth around himself.

He had never thought the picture Sai made, lips stretch around his hot flesh, head
bobbing up and down to wet sucking sounds, would be a picture he could ever find erotic. But it was. Especially when he looked up and moaned around Naruto’s cock. His balls
tightened impossibly at the image.

Sai pulled off, pumping with his free hands as he kissed the head and let his
tongue find and slip briefly into the slit stretched by the heavy arousal in front of him extracting the pre-cum within greedily. Naruto’s hands were gripping the rock beneath him so he
didn’t slip off. He watched through eyes half-lidded as Sai pulled back completely and stood, his erection bobbing proudly beneath a trimmed patch of black pubic-hair as it cleared the
water.

“Sai?” Naruto asked worriedly as his legs slipped back into the water
from where they had hooked around his back, suddenly realizing how vulnerable a position he was in. “What—”

“Relax. It’s the opposite of what you’re thinking.” Sai
spat on his index and middle fingers reached back while he fondled himself and—

Naruto had to look away, relieved and nervous and embarrassed all at the same time.
He had no idea how someone would voluntarily stick something back there. But if the moans where anything to go by, Sai didn’t mind at all.

“I may be experienced with this sort of thing. But it’ll hurt if I
don’t prepare myself first.”

“Uh…oh.” He bit his lips as his own entrance throbbed at the
thought with phantom pain. Naruto’s erection began to droop as guilt tamped his lust. “Sai…you don’t have to…just to prove a point…”

“I want to. It’ll feel good, for both of us. Please trust me on
this Naruto.”

Naruto sat up awkwardly, trying to look anywhere but at the now moaning and
slightly hunched Sai, whose fingers had disappeared behind him while he panted and ministered to his own arousal.

“Doesn’t it hurt?”

Sai paused to spit on his fingers again before he returned them to his behind. He
shook his head when he looked up. “No. It’s a bit uncomfortable for a while, but the muscle stretches easily enough. It’s like any other muscle in your body. If you stretch it
properly before a workout, you won’t strain it.”

Naruto blushed and muttered, “some workout.”

“You’re a bit biased. Your first time was forced and probably without
any preparation, right?”

He tensed and nodded shortly—unwilling to elaborate or dwell on his first
experience with a man.

“Here, switch places with me. You might as well do some of the work.”
Sai said, motioning him to stand, which he did. Sai took his place, but only put his hands on the surface of the rock as he bent over, exposing his rear to a now brightly blushing
Naruto.

“There’s…no hair,” said he dumbly, unable to look away
from the glimpse of pink flesh between the compact globes of Sai’s smooth arse.

“I’ve always thought having hair down there is silly. When you crap and
then wipe yourself, all you’re doing it mushing it into the hair down there. When there’s no hair its no much easier and quicker to clean.” He looked back and wiggled his hips
playfully. “Sexier this way, too.”

“If you say so,” Naruto replied dubiously. “Um…so what am
I doing here?”

“Wet your finger in your mouth, then stick it in.” At Naruto’s
continued sceptical look he rolled his eyes. “I’m not going to break. Just…get comfortable with the idea that sticking something back there isn’t going to break
me.”

Naruto stuck his right index finger into his mouth, getting it soaked with saliva.
He tentatively moved his other hand to touch the sculpted flesh of the tight muscle before him and was almost startled when Sai moaned and pushed back against the hand. “Hurry up,” he
urged.

Naruto removed his finger from his mouth and positioned it against the exposed
rosebud that was already damp and leaking a bit of Sai’s earlier preparation. He pushed forward, submerging his finger slowly, pausing when the muscle around his finger contracted and
Sai’s head fell limply to the sound of a groan. Sai abruptly pushed back all the way to his knuckles, sinking the finger completely inside.

It was tight, Naruto noted, but went in easily enough. It felt soft and silken and
hot inside Sai.

“Mmm, now take it out and this time put in two and try to stretch it
gently.”

Naruto throat bobbed as he followed instructions wetting his middle finger as well
this time. Sai wiggled as Naruto eased his fingers inside again all the way.

“Touch me, too.”

Naruto hesitated before steeling himself and reached around to wrap his fingers
around Sai’s flagging erection. Every time he moved his fingers to stretch the impossibly tight opening, Sai’s erection would throb as his muscles clenched. And while his erection
wasn’t straining anymore, it was leaking an obscene amount of precum all over Naruto hand.

“—three. Put three in.” Sai ordered brokenly.

“You’re hurting,” Naruto noted, upset as he withdrew his fingers.
“I knew this was a bad idea.”

“I’m not—”

“You are, you’re not as excited anymore.”

“It’s going to soften either way for a while,” Sai explained a
bit impatiently. “You’re touching my prostate directly, or close to it, so the feeling gets intense enough that my body starts to focus back there rather than up
here. It feels good. Trust me.”

Naruto frowned but wet his ring finger and his other two, squeezed them together,
and eased them in as instructed. Sai hissed for a moment and tensed at the large intruder, but let out a quick breath and pushed back a moment later. Naruto continued to massage the spongy flesh
in his hands as he stretched his three fingers open where they were buried.

“That’s fine,” Sai panted eventually. “I’m good and
ready. Just—get it as wet with your saliva as you can before you put it in…and go slow.”

“Sai—”

“Stop being a chicken, I want your cock inside me, okay? You’re not
forcing me, and I’m not doing this to make a point. I want you to fucking stick your dick in me and fuck me. Get it?” Sai sounded incredibly aggravated for some reason.

Naruto grimaced as he looked down at his own erection, only half-hard and drooping
between his legs. He knew this hurt. He knew because it had happened to him. He spat on his hand and worked himself back to a more tensile state. He leaned over and spat again, coating his
head and working it down and around his still malleable shaft.

He move forward and positioned his arousal, tip just brushing Sai’s opening.
The brief contact of flesh made Sai urge him on by pushing back, missing impaling himself when the still floppy flesh didn’t quite have the necessary rigidity to breach without a helping
hand. Naruto winced and muttered a brief prayer to the kami before he aligned himself with his hand and slowly pushed forward.

The spongy flesh of his head spread Sai’s opening obscenely as it
entered. And it only worsened as Naruto’s mind processed the burning and moist heat and crushing pressure that engulfed him. Blood surged into his erection eliciting a low cry of surprise
from beneath. The proportion of his shaft to Sai’s tight rear seemed impossibly unbalanced. Sai shuffled his legs wider which made Naruto grab his waist tightly, fearing he would topple
over and rip something open. Sai just moaned from his position and arched his back as he adjusted to his massive intruder wiggling his rear in a way that made Naruto want to blow his load
prematurely.

Obviously and vocally impatient, Sai shoved backwards, burying the head and several
more inches of Naruto into him before Naruto could react. The increase in pressure only served to made him harder and he let out a hiss of compressed air forced from his lungs as razor-sharp
pleasure raced and thrummed through his veins.

“Fuck.” Sai moaned. “Oh fuck you’re big. Don’t move.
Let me adjust.”

Naruto instantly obeyed, terrified of hurting Sai even as his entire body began
vibrating with the ill concealed urge to shove his length into that wonderfully warm and breathlessly tight cavern. He could practically feel Kyūbi in his mind as he suddenly became all too
interested in the proceedings playing out in the real world. Naruto tried valiantly but ultimately failed to stop the surge of the vicious red chakra that poured into his system from the seal.
His chest rumbled with a growl he couldn’t check as his canines ripped into his lower-lip, drawing blood; fingers cramped as his nails thickened and sprouted claws in their place. The worst
was his cock and balls, where the chakra seemed to pool and amplify his lust until there was only his cock, his balls, and the moaning thing spread in erotic submission before him. He was only
vaguely aware of Sai pushing back against him, urging him on once again as he shoved forward inexorably, holding Sai in place as he squirmed as he was filled past overflow and beyond. Until he
had crammed every turgid inch into that warm sucking hole and his blond pubes pressed tightly against the pale shapely flesh of Sai’s cheeks.

Naruto tore his mind viciously back from the brink of instincts that did not belong
to him. Panting harshly he forced himself to stop even as he wanted to start pounding back and forth until the burning in his groin ceased and the warm body beneath him begged him for mercy, even
as all his nerves fired from his cock right up his spine to flare pain and pleasure behind his eyes. Even then he stopped.

“S-sai?” He half demanded half requested in a voice more animal
than human.

“Shit, so full.” A full blooded moan vibrated the body stuck on his
cock then. Naruto whimpered as his dick hardened that fraction more, until it felt more like steel and close to bursting. “Okay…fuck. Just…just fuck me.”

What thin rein he had on his lust shattered. He pulled back, sucking friction
making a delicious counterpoint, and slammed back in. He held Sai’s hips steady as his flesh began to beat a tempo with every piston of his hips. He was vaguely aware of Sai’s vocal
wails and begging for more, and harder, and faster; but juiced as he was on Kyūbi’s chakra, it remained only a vague consideration, second to satiating the burning acid pooling in his
veins. He slammed into Sai again and again. The thick scent of musk and arousal soon muted the salt and soapy smells of the bath, doubly so when Sai burst into the water again, unable to hold
back any longer under the unflagging battering of his prostate. Then he just held on for the rest of the ride, keening and panting and begging with every thrust.

Naruto lost track of time in his lusty haze of flesh and warmth and aural sounds of
arousal. The tension in his groin built and built until he couldn’t stand it any more. One last thrust, deep, rooting himself into Sai and he came with a primal roar that echoed to and fro
among water and rock long after his lungs exhausted themselves. He could feel the cum leaving his shaft and gushing into Sai. It felt like it went on forever.

When he finally came back to himself he was still planted. Sai’s arms
trembled where they braced himself against the rock; his essence, the remains of his multiple orgasms, dotted the water pooled around his legs.

Guilt hit him like a sledge as he slowly pulled his flaccid cock from Sai’s
rear. White leavings immediately gushed from the gaping hole that he had left of Sai’s ass. He nearly cried with relief when there was no red-tint to the liquid. No sign of tearing. The
muscle winked at him as Sai tensed momentarily and let out a long tired sigh.

Naruto grabbed him and helped him stand, only for his own shaky legs to collapse
under him taking Sai with him. He pulled Sai into his lap as he settled heavily on the shallow ledge meant for sitting. “Fuck…are you alright? Sai?”

Sai just flopped backwards, resting his head on Naruto’s shoulder, his breath
coming in panting heaves.

“Sai?” Naruto tried again, nervously.

He tilted his head into Naruto’s neck, which preceded his entire body
twisting until he repositioned himself, legs straddling Naruto’s, his face never truly leaving Naruto’s neck.

“Sai?”

“Mmmm – shut up.” Sai mumbled as he lazily leaned back and
wrapped his arms around Naruto’s neck. “I’m trying to enjoy my hard-earned afterglow in peace.”

With only enough time to blink and start a sigh of relief before he was interrupted
when Sai leaned forward and brushed their lips together. It didn’t stop there. Sai tilted his head and hummed with deep satisfaction as he pressed another lazy kiss into Naruto’s
unresisting mouth.

It seemed a small thing, kissing Sai, after where he’d just stuck his dick.
Naruto anchored Sai onto his lap by wrapping his arms around his waist. Sai was strangely affectionate as he made liberal use of his tongue to tempt Naruto’s out to play. It didn’t
last long as Sai eventually broke the contact and rested his head once more in the crook of Naruto’s neck.

“So, good huh?” Sai said, sounding inordinately smug even through his
exhaustion.

“I thought I’d hurt you,” Naruto muttered guiltily, his hands
absently playing up the plane of his back. It terrified him that he’d been so close to losing control. It was always dangerous when Kyūbi came out to play when he was having sex.
Strangely, that only seemed to happen when his partner was male. But it wasn’t like he’d had a big enough sample to make that determination final. He had a feeling though that Kyubi
was totally into the whole domination thing.

“I’ll be a bit tender tomorrow,” Sai said slowly, “but it
didn’t hurt. It was the best fuck I’ve had in a long time.”

Muscles Naruto hadn’t known were tense, relaxed. “Thanks, Sai.”
Naruto muttered into his hair. “Does this mean you’re going to stop calling me dickless now?”

“And share a secret I’d rather keep all to me, myself, and my sore
ass?” Sai hummed contemplatively. “I’ll have to give that some more thought.”

“Whatever.”

“And while I’m thinking about that,” Sai said slowly,
deliberately smug in his delivery, “you can think up what you’re going to tell Sakura in the morning.”

Every muscle in his body tensed. “What are you talking
about?”

“Maybe you forgot but, Naruto, this here is an open air bath. And she
was soaking on the woman’s side before you came in which means she just heard every growl, every moan, and – every – single – word – we –
said.”

Naruto’s mind went blank.

Sometime later Sai snapped his fingers. “Stallion. Yeah. Suitably cheesy,
descriptive, and no-one except me will take it literally. In fact, everyone will probably just think I’m making fun of you. Yeah. Stallion. What do you think?”

“Naruto?”

“…Naruto?”

“Konoha to Naru-chaaaaan? Are you there?”

A longer pause. His sigh, when it came, was long, low, and morose. “I wonder
if this is what a kid feels like when he breaks his first toy.”
