The Devil's Whisper in Naruto (SI/OC)

The salt water hit my skin like a thousand needles, but it was exactly what I needed. My blood had been running so hot I thought I might spontaneously combust right there in that tiny inn room.

"Eishin, what the hell?!" Naruto's voice cracked as he surfaced, spitting seawater and glaring at me with those blue eyes full of indignation. "You can't just grab people and throw them off cliffs!"

I treaded water easily, letting the cold waves wash over the tension coiled in every muscle. "Training exercise," I said simply, though we both knew that was bullshit. Sai emerged silently nearby; he didn't complain about everything like the blonde knucklehead.

I'd spotted them heading back toward the inn just as I'd stepped out of our room, and I could let them see my work in there.

Sakura was still sprawled face-down on the bed where I'd left her, drooling, unconscious, and thoroughly... compromised.

Her long pink hair had been a messy halo around her flushed face, shorts, and sheets darkened with evidence of just how responsive her innocent body had been to my ministrations.

Her uptight cunt was so swollen and sensitive, the soaked gusset molded to every tender contour like a second skin...

Fuck. The memory alone made my cock twitch even in the freezing water.

The way she'd tried so hard to muffle those sweet little moans under the pillow, how her hips had lifted off the mattress seeking more contact, the gradual way her thighs had fallen open as I'd worked her through the fabric... And that final moment when she'd completely lost control and gone crazy.

The fact that she was a squirter just like her mom didn't help—other families passed down kekkei genkai; this one passed down geysers.

No shinobi heritage, but clearly that household has a hidden of its own.

That aside, I should have known better. Virgin nerves combined with medical chakra and my admittedly skilled fingers?

Of course, she'd passed out.

Part of me felt a bit bad about pushing her inexperienced body that far. But the other part—the part that was rock hard despite the arctic temperature of this water—wanted nothing more than to march back up there and finish what I'd started.

But that would ruin everything.

Popping her cherry now, when she was unconscious and unprepared, would be sloppy. Satisfying in the moment, maybe, but it would complicate my carefully laid plans.

Besides, I'm no saint, but I wasn't that brand of bastard. The line must be drawn somewhere.

Also, I didn't just want to fuck Sakura Haruno— considering how perfectly I'd been conditioning her responses, I could've had that without breaking a sweat.

No, I wanted to own her completely. Mind, body, and that fiery spirit of hers.

And that required patience, I wasn't sure I possessed right now.

We trudged onto the rocky shore, water streaming from our clothes.

Naruto shook his blonde hair like a wet dog, grumbling under his breath about "crazy team leaders" and "unnecessary swimming lessons."

But then he stopped mid-complaint, his eyes widening as he rifled through his soaked backpack. He pulled out what had once been a carefully wrapped bento, now a soggy mess of cloth and ruined rice.

"EISHIN!" Naruto's voice cracked with genuine distress. "Look what you did! You perverted bastard!" He held up the dripping package like evidence of a war crime.

"Oh, sorry about that, Naruto," I said with a small smile, running a hand through my wet hair. "There's a restaurant in town—lunch is on me."

"We already ate," Sai interjected in that flat tone of his, wringing water from his crop top without any apparent concern for the ruined food.

"Tch, Tsunami-san made this specially for you and Sakura-chan as a thank you!" He pointed a finger. "She got up early and everything, and now it's completely ruined!"

Tsunami?

My mind was already spinning, though. Tsunami... Bridge-builder Tazuna's daughter-in-law. Inari's mother. From my past life memories, I could picture her clearly: gentle brown eyes, long dark hair, that soft maternal warmth that had made her such a perfect supporting character. Twice widowed, struggling to raise her son alone while her father-in-law chased his impossible dream.

But that was in the show, in this, the bridge builder was dead and she…..

I straightened, putting on my most contrite expression. "Then I definitely need to apologize to Tsunami-san in person."

The words tasted like justification, but my body was already responding to the possibility.

"You're being a smartass again." Naruto squinted at him, suspicious.

"Would I?" I coughed, then gave an exaggerated sigh and placed a hand on my chest. "I solemnly swear to deliver a heartfelt apology to the nice woman who entrusted us with soggy rice and motherly kindness."

My last shadow clone had reported that Inari spent near that merchant. Kid hardly left the man's side unless he was running errands. Barely visiting home and even with home close, he hadn't spent the night there. Instead, he rested where he was provided.

The kind of place where you sleep on crates and don't ask questions. The kind of job you take when you've got nowhere else to go.

Which meant right now, a beautiful, lonely widow was probably sitting in an empty house, thinking about kind strangers who'd protected her son.

Kind eyes. Tired smile.

The kind of woman who'd fall for a little warmth in the right places.

Dammit, I really was a piece of shit for thinking like this when I was this wound up. But the blaze in my blood hadn't subsided despite the freezing water, and my self-control was hanging by the thinnest of threads.

"Wait, hold on." Naruto's brow furrowed as he processed what I'd said. "How'd you know Tsunami-san's a mom? I never said anything about that."

His eyes narrowed, full of suspicion. Not the sharp kind, either—more like the slow-building kind you get when you find something weird in your food and wonder if it's just seasoning or a dead bug.

That's not the look you give your team leader, dude. You're hurting my feelings.

But, to be fair, he had every reason to doubt me. Especially with how I left his teammate and when I was currently carrying a very incriminating pair of his own mother's panties in my pocket.

Yeah.

Kushina's... panties.

Fuck.

It was not just the bento that was ruined.

Those panties had been my moral support. A physical tether to something wild and glorious. And now just soggy, slated silk.

Fucking fuck.

Yet, with all my sufferings, I still had no time to mourn.

I tried not to sigh, cursing my recklessness, I put on a smile, I didn't feel the least. "I'm just awesome like that," I said with a casual shrug, wringing water from my vest. Naruto was dumb as a brick sometimes, but he had instincts.

He didn't look impressed. Naruto crossed his arms and muttered, "More like creepy like that."

Sai chose that moment to chime in, voice even and clinical, like he was describing cloud formations.

"Eishin-san likely deduced it based on what you said earlier, Naruto," he explained to Naruto, gaze drifting somewhere to the left of both of us. "You mentioned that Tsunami-san was grateful. Gratitude implies something personal. Also, Eishin observed that you've grown close to Inari during the escort. That level of familiarity is usually earned through family ties. And finally…"

He paused thoughtfully.

"…Eishin-san is a jounin currently assigned to this investigation. Inari works closely with the merchant under scrutiny. He would logically be part of the inquiry."

Naruto blinked slowly, like his brain was buffering. Then he looked back at me, frown softening just enough to signal confusion over irritation.

"….Huh."

….Huh. I intoned him inwardly.

Eventually, I shrugged. "See? Awesome like that." I said, because I was not an idiot to refuse free credit.

He was not convinced.

"Right, well..." I cleared my throat, forcing my mind away from widowed mother and soggy undergarments. Duty first. "How's the shadow clone training going? Teamwork drills, coordination—any of that sticking yet?"

Sai opened his mouth to respond, but Naruto's face suddenly lit up with that particular brand of mischievous glee that made my stomach drop.

"Oh, speaking of training..." Naruto's grin stretched wide, practically vibrating with barely contained excitement. "I've been working on something special!"

It wasn't just…. It was that wild, toothy, gremlin expression Naruto got when he thought he was being clever.

"Lemme show you—"

A grin I was starting to dread.

"Naruto. No need." I took a step back. "There's really no need for a demonstration—"

"Nah," That grin widened. "It's cool, I promise…. you will like it. I've been perfecting this technique just for you."

"Naruto," Sai stepped forward with uncharacteristic urgency. "Perhaps this isn't the appropriate—"

"Harem Jutsu!"

When it cleared, five absolute bombshells stood where Naruto had been. Each one was tall, radiant, and somehow, infuriatingly, different in appeal.

A blonde with cascading waves, a brunette with smoldering dark eyes, a redhead with porcelain skin, a raven-haired beauty, and one with silver locks that caught the light like spun moonlight. They wore matching bikinis in various colors, the fabric clinging to curves that defied physics.

Perfect breasts strained against thin triangles of fabric, waists so narrow I could probably span them with my hands, legs that went on for miles, and necks so elegant they begged to be kissed. Every inch of exposed skin was flawless, sun-kissed perfection.

My brain short-circuited.

After that session with Sakura, my body was already a live wire. Now this visual feast was laid out before me like some kind of cosmic joke. My mouth went dry as my gaze involuntarily traced every curve, every line, the way the wet fabric clung—

But these weren't real women.

This was Naruto.

Male. Definitely, absolutely male underneath all that transformation chakra.

The rational part of my brain knew this. Screamed it, actually. But my body was responding to pure visual stimuli, and the contradiction was making my head spin. Beautiful feminine forms that were somehow still fundamentally him, and I liked women, actual women, not—

Fuck. I really shouldn't have taught him shadow clones.

They closed in fast.

Five bombshells circling like sharks scented blood—mine, apparently. Two hooked their arms around mine, pressing close enough I could feel their heat through my clothes. Their skin was soft, dangerously warm. Like a bath you didn't realize was too hot until you were already in.

"Eishin-sensei," purred the brunette on my left, her breath tickling my ear, voice laced with syrup and sin. Her fingers traced along my forearm. "You look so tense… Shouldn't a good student help his teacher relieve stress?"

Where the fuck did you hear to talk like that?!

The redhead on my right giggled, a sound like wind chimes. "Onii-san, you're all wet from the water. Let us help you dry off~"

That term of endearment didn't help. Not when she leaned in like that—hair brushing my jaw, lips barely a breath away from contact.

"Sensei's so strong..." Behind, silky hair brushed against my neck as another whispered. "We've been such bad students, haven't we?"

The silver-haired beauty stepped closer, running her hands down my chest. "Maybe we need some... private tutoring?"

And the blonde with familiar whisker marks tilted her head with mock innocence. "Onii-san, your heart is beating so fast. Are we making you nervous?"

Their skin was impossibly soft where they touched, warm and real despite everything my brain knew. The press of curves against my arms, the way their breasts brushed against me with every movement.

My body responded exactly as it had with any other woman, betraying every rational thought I tried to maintain.

"Looks like….." I drew in a heavy breath, my voice dropping to something dangerous, "You could use a bit of discipline as well."

They all gulped in unison. The blonde just giggled, trying to play it cool. "Oh no, what are you going to do to us, sensei?"

The brunette bit her lip. "We've been so naughty... maybe we need to be punished?"

"Please be gentle with us, onii-san," the redhead whispered. "Or not…"

….. why the fuck was he good at this?

I moved.

My fingers found the brunette's nipple through the thin fabric and pinched hard. She gasped, back arching as her eyes went wide, before dissolving in a puff of smoke with a breathless "Sensei's... so rough—!"

The redhead tried to step back but I caught her, my hand sliding down to grip her ass firmly. She moaned as I squeezed, her form trembling before she too vanished with a whispered "More..."

The silver-haired one barely had time to gasp before I wrapped my hand around her throat, I brushed my fingers down her spine, before tapping her lower back. "Onii-san, I—" She dissolved mid-sentence.

The raven-haired beauty met the same fate as my hand tangled in her hair, while I found her blossoming breast, plump and eager, fondling them hard enough to make her eyes flutter closed with a final, shuddering "Please..."

Only one remained. Naruko, the blonde with whisker marks, took a half-step back with genuine nervousness flickering in her blue eyes, though she still tried to maintain that sultry pose.

"…You wouldn't hurt a cute girl, would you, sensei?" she asked sweetly, voice trembling just enough to seem genuine. "Not one who just wants to be close?"

"Oh, I wonder," I said with a grin and a tent in my pants.
