The Hokage Tower's private training chamber was supposed to be off-limits after hours.
Tsunade had made that rule herself—decades ago.
Tonight, the rule was being spectacularly broken.
She leaned back against the wide desk at the far end of the room, arms crossed beneath her massive chest, the deep red haori slipping off one shoulder to reveal the black silk top that strained against her curves.
Golden hair cascaded wild and loose.
Amber eyes narrowed, watching Naruto like a predator sizing up prey.
"You've been busy, brat," she said, voice low and smoky. "Konan. Hinata. Sakura. Word travels fast when you leave chakra signatures that scream 'Nine-Tails rut' all over the village."
Naruto stood in the center of the room, shirt already discarded somewhere near the door.
Sweat glistened on his skin from the light spar they'd just finished—or pretended to finish.
The orange glow in his eyes hadn't faded; if anything, it burned brighter now.
"You jealous, Granny Tsunade?" he asked with that infuriating grin.
Her eyebrow twitched.
"Call me that again and I'll shatter every bone in your body."
She pushed off the desk and stalked toward him, hips swaying with deliberate menace.
When she reached him she grabbed his chin—hard—tilting his face up to meet her gaze.
"But I'm not jealous," she murmured. "I'm **curious**.
The boy who used to trip over his own feet is now fucking his way through the strongest kunoichi alive… and still has energy left over.
Impressive."
Naruto's grin turned feral.
He caught her wrist, not pulling away—just holding.
The heat of his palm seared her skin.
"Then let me show you how impressive."
Tsunade laughed—dark, throaty, dangerous.
She shoved him backward until his back hit the padded wall.
Then she followed, pressing her body flush against his, breasts crushing against his chest.
"You think you can handle me, kid?"
Her hand slid down, palming the thick bulge straining against his pants. "I've broken men twice your size."
Naruto groaned low when she squeezed.
"I'm not most men."
He flipped their positions in a blur—hands pinning her wrists above her head against the wall.
She could break free in an instant.
She didn't.
Instead she arched into him, grinding her hips slowly, deliberately.
"Then prove it," she challenged. "Fuck the Fifth Hokage like you mean it."
Clothes came off in a frenzy.
Her haori hit the floor.
The silk top followed—ripped at the seams because Naruto's patience had officially ended.
Tsunade's breasts spilled free, heavy and perfect, nipples already peaked from the cool air and anticipation.
Naruto's mouth found one instantly—sucking hard, teeth grazing just enough to make her hiss in pleasure.
His other hand kneaded the opposite breast, rough and possessive.
Tsunade's head fell back against the wall, fingers tangling in his blond hair.
"Fuck—yes, like that—"
He dropped lower, kissing and biting a trail down her toned stomach until he reached the waistband of her pants.
Yanked them down along with her panties in one motion.
She was soaked—glistening, swollen, ready.
Naruto didn't tease.
He hooked one of her legs over his shoulder, spread her open with his thumbs, and buried his tongue inside her.
Tsunade cursed loudly—filthy, unrestrained.
Her hips bucked against his face as he devoured her: long, flat licks, then fast flicks over her clit, then sucking hard until her thighs trembled.
She came fast and hard—back arching, nails scraping his scalp, a throaty moan echoing off the walls.
Naruto stood, wiping his mouth with the back of his hand, eyes blazing orange.
"Not done yet."
He spun her around, bent her over the desk—ass up, breasts pressed flat against the wood.
She braced on her forearms, looking back at him with a challenging smirk.
"Do your worst, brat."
He lined up and thrust in—deep, brutal, all the way to the hilt in one stroke.
Tsunade's eyes rolled back, mouth falling open in a silent scream of pleasure.
"Fuck—**so big**—"
Naruto didn't let up.
He fucked her like he was trying to imprint himself into her soul—hard, relentless snaps of his hips that made the desk creak dangerously.
Each thrust drove her forward, breasts bouncing wildly, skin slapping against skin.
Tsunade pushed back to meet him, meeting every stroke with equal force.
"Harder—damn it—**wreck me**!"
He reached around, fingers finding her clit again—rubbing fast, merciless circles while he pounded into her.
She shattered a second time—walls clamping down so tight he nearly lost control right then.
Naruto growled, pace turning erratic.
"Gonna fill you up, Tsunade-sama—"
"Do it," she gasped. "Mark me—claim your damn teacher—"
He slammed home one final time and came with a roar—hot, thick pulses flooding deep inside her while she milked him dry, trembling through the aftershocks.
They stayed like that for long moments—panting, sweat-slicked, connected.
Finally Tsunade laughed—breathless, satisfied.
"You pass… for now."
Naruto pulled out slowly, watching his release drip down her thighs with dark satisfaction.
He leaned over her back, kissing the nape of her neck.
"Still think I'm just a brat?"
She turned her head, smirking despite the flush on her cheeks.
"I think… you're dangerous.
And I think the storm's only getting started."
Outside, thunder rolled again—louder, hungrier.
Somewhere in Konoha, more kunoichi were beginning to feel the pull.
**To be continued…**
(Next tease: First group scene? Ino catches wind and crashes the party? Or maybe Temari arrives from Suna with her own demands?)
