A/N: [EVERY CHARACTER IS MADE TO BE 18+]
-----------------------------
Tsunade sat behind her Hokage desk, her fingers drumming an erratic rhythm against the polished wood as her other hand fanned herself lazily. Sweat glistened across her ample cleavage, dripping in beads down to her abs. Her grey shirt, clinging tightly beneath the signature green jacket, had soaked through, faintly revealing the outline of her areolas and the erect points of her nipples. The humid summer air did her no favors, and she clicked her tongue in irritation at the lack of wind.
She sighed, glancing up from the paperwork stacked like little towers in front of her. With a tired wave of her hand, she muttered, "Ryoku, be a dear and get me a popsicle, it's incredibly hot today." As she pulled her damp shirt away from her chest, her nipples briefly slipped into view, glinting with sweat. Ryoku, who had been diligently standing off to the side, turned a violent shade of red the moment he caught the glimpse, jerking his head away with such speed it was a miracle he didn't give himself whiplash.
"A-at once, Lady Tsunade!" he stammered, already facing the door. He marched stiffly like a soldier under inspection, his body clearly trying to behave while his mind reeled.
The door shut with a soft thud behind him, and Tsunade's lips curled ever so slightly. Her hand wandered from the desk, skimming down her tight, toned stomach, and resting on a growing bulge that tented her damp blue pants. Fingers rubbed the shape idly. "He's cute…" she murmured, her voice low and amused.
Meanwhile, Ryoku stomped down the stairs of the Hokage mansion, every footstep fueled by a mixture of panic and shame. His face burned. 'Oh man... This job is really something… No wonder she previously had Shizune as her aide, it's so hard for men like me to take it…'
His internal complaints faded, only for insecurity to crawl back in. 'Man... I'm hardly one… I know an attack by Pain is coming in a year, but I'm not able to make any progress to get stronger. I'm just wasting this knowledge! I've been here for a month already!'
Clenching his fist in frustration, Ryoku quickened his pace, boots echoing off stone steps as he passed through the mansion gates into the streets of Konoha.
The city was alive with the midday crowd — merchants peddling fruit, kids chasing each other with wooden shuriken, shinobi chatting by food stands. Ryoku looked down, unable to meet their eyes. 'Some of these people are going to be dead because of me. Even if they return to life, that trauma of having their homes destroyed and seeing dead loved ones will still linger!'
His spiral of guilt was suddenly derailed by a flash of light. A bright blue screen materialized in front of him mid-step, cutting off his train of thought — and his movement. He didn't realize he'd stopped until he bumped shoulders with a passing man.
"Hey! Watch where you're going!" the older civilian barked before storming off in irritation.
Ryoku didn't hear him. His attention was locked on the floating screen, its glowing letters pulsing with clarity:
[Ryoku. Welcome to the Naruto World. This is a world me and my friends have made and we've chosen you after your unfortunate death. We've noticed you have the perfect… traits for this world.]
Ryoku, having long passed his shock threshold after a month of reincarnated life, calmly stepped aside and leaned against a wall to stay out of the way. "Traits? What do you mean by that? And you guys are the ones responsible for me being here? Why would you bring me to a place like this?!"
The text blinked out and was replaced with:
[Yes, we have brought you here, to give you another chance at life. It was either that or eternal nothingness. And about traits, if you haven't noticed already, this world is inhabited by futa's instead of your ordinary females. This means that every girl has a penis, as well as a pussy. Do you now understand why your traits align?]
Ryoku felt all the color drain from his face as memories — deeply personal and painfully embarrassing — resurfaced. Images of Futa Hentai magazines and secret bookmarked folders flashed in his mind. "N-no, you m-must have the w-wrong person!" he stuttered.
The system wasn't having it.
[Ryoku, we know everything about you. From your height of 175cm, your shoe size, and even the size of other… Things…]
His hands shot downward, shielding his crotch on instinct as he darted his eyes around. No one was looking. Slowly, reluctantly, he dropped his hands, exhaling in defeat. "Fine. You know me. So what do you want?!"
Though his voice was defiant, the humiliation still burned under his skin.
[We're aware of the upcoming calamities, from the Akatsuki, to Obito, to Madara and even Kaguya and beyond. As a result, we've decided to help you out.]
Ryoku's eyes narrowed, curiosity replacing some of the shame. "Continue…"
[We've assigned this Futa System to you. The more missions you complete assigned to you by the System, the more XP you gain, making you stronger. Certain missions will give you certain skills sometimes, and how powerful a skill is depends on how difficult the mission is.]
Excitement swelled in his chest. A grin broke through. "So… Hypothetically I could gain skills like Rasengan??"
[Yes.]
Ryoku clenched his fists in pure glee, ready to leap into the air — but the heat, and the sweat tracing down his face, snapped him back to reality. Lady Tsunade. The popsicle. The time.
"Shit!"
He bolted to the nearest corner store, grabbed the popsicle, threw down the money, and sprinted back to the mansion, narrowly avoiding — and occasionally colliding with — other pedestrians.
By the time he reached the top floor, he was winded but intact. Knocking on the office door, a sharp voice from within barked, "Enter!"
Tsunade sat on her desk, arms crossed, expression tight with annoyance. Her shirt was even more soaked now, nearly transparent. Her legs were spread without care for modesty, revealing the thick, sweaty bulge beneath.
Ryoku, catching a glimpse, nearly short-circuited. "S-sorry for being late, Lady Tsunade!" he blurted, eyes darting to the floor.
Tsunade's gaze was cold, a predator sizing up prey. "How do you intend to make up for this? I'm sure you do not want to be fired, do you?"
Ryoku's memories flashed — bugs, raw fish, sleeping under trees. "No, Lady Tsunade!" he said, quickly.
She didn't let up. "Then how will you make up for it?"
As if on cue, the screen blinked into existence again:
[MISSION]
[Offer to be spanked by Tsunade to make up for your error. Reward: 20XP and Rank Up to Genin!]
"What?! But I—" Ryoku stopped himself. She was waiting. His opportunity was waiting.
"What was that?" Tsunade said, eyes narrowing.
"Y-y-you…" he stumbled.
"Spit it out."
"YOU CAN SPANK ME!" he shouted.
A moment of silence. Then Tsunade blinked — once, slowly. Her expression morphed from surprise to something far more dangerous. A slow, wicked grin stretched across her lips. Her eyes gleamed.
"So be it then…"
Rising from her desk, she strode to her chair, her backside swaying hypnotically. Ryoku's eyes widened at the size and bounce of her ass, each movement exaggerated by sweat-slick skin and her tights pants.
She sat down, spread her legs, and tapped her thick thighs. "Come on now, we don't have all day."
