------------------------------

With Tsunade's lewd, desperate expression, Ryoku didn't even need to hear her beg again. His body reacted on its own, his hands already fumbling at his belt, hurriedly unbuckling it. The thought of sticking his cock inside Tsunade's oversized, pillowy ass sent a torrent of blood south, giving him a raging erection in seconds.

For once, this wasn't just another lonely night with his hand and some filthy doujin. No, he was there in person now. The person in the comic he'd usually jack off to. It was a perfect, filthy full-circle moment. Breathing heavily from pure arousal, Ryoku dropped his pants, yanking down his boxers as his cock sprang free, standing proud. His hands instinctively returned to Tsunade's ass cheeks, sinking into the softness with reverence. "So soft…" he muttered to himself, almost breathlessly. Up close, it was even better than he'd imagined.

Tsunade's ass creased perfectly at the bottom, giving it that youthful, impossibly plump look. Her waist was thick, but her ass was even thicker—wide enough to dwarf Ryoku's hips. Every small squeeze sent ripples cascading across the heavy flesh like waves in water.

Tsunade, too stimulated to wait any longer, reached back and grabbed Ryoku's cock in her hand even as she continued her lazy strokes inside Koharu's stretched ass.

"Oh?" Tsunade said, her tone revealing her surprise. "Ryoku, you never told me—" She stopped mid-sentence, pressing his shaft against her forearm to measure its length properly. Her eyes went wide. "B-but this can't be… You of all people?!"

Tsunade felt… intimidated. Ryoku's cock was bigger than any dildo she'd dared to try. She was still a beginner when it came to dildos, but even browsing the shops, she hadn't seen anything quite like this. Not this thick.

Seeing her hesitation, Ryoku's heart raced faster. "She thinks I'm big?" he thought in disbelief, looking down at his cock. Six inches—seven on a good day. Scratching his head, he tilted it in confusion. 'She's doing all this drama over six inches? I was average back home. Maybe standards are different for boys in this world…' He couldn't explain Tsunade's reaction.

Tsunade was sweating now, a mixture of pressure and nerves. Feelings Ryoku understood too well since being transmigrated. "S-sorry, I'm j-just… I'm just unprepared!" she stammered, her usual confidence crumbling.

She was about to ask him to take it easy when Ryoku's palm cracked against her ass with a sharp "CLAP!" Her flesh reddened instantly beneath the force. The sound echoed through the humid, filthy room—startling even Koharu out of her lust-drunken stupor.

"Eeee!" Tsunade squealed, the sting from the slap mixing with her anxiety to make her shudder in anticipation. "Take it easy!" she pouted, her lips curling into something softer.

Ryoku smirked, enjoying her reaction, and rubbed her reddened cheek affectionately before planting a kiss on it. "If you want me to take it easy, you'll have to behave. You can do that, can't you?" he teased, the threat of an intense ass pounding hanging in the air between them.

Tsunade, too prideful to fully submit but smart enough to know when she'd lost, clicked her tongue. "Just get this over with, enough with the game—" Another sharp slap silenced her, this time on her opposite cheek. "Ouch!" she yelped, rubbing the sting away. "Ok fine. Please just… go easy." She submitted at last, lips pressed together, sweat rolling freely down her flushed face and into the deep valley of her cleavage.

Holding his six-inch "wonder" proudly with both hands for the first time, Ryoku guided his cock along the bumpy rim of Tsunade's anus, generously spreading precum as he traced slow, deliberate circles toward the center.

Before long, he arrived at the gateway between those two perfect globes. Pressing forward, he felt resistance. Tsunade's body fought back, her anus struggling to accept him. Glancing up, Ryoku caught her worried expression and, suddenly, it clicked.

'She's nervous, so her body's closing up. Same as any other hole—you can't exactly take care of business if you're tense. And this ain't any different. The backdoor stays locked if you don't relax.'

Resting his hand on her ass, Ryoku whispered calmly, "Tsunade, inhale deeply… and exhale. Try to relax. Calm your nerves." Tsunade obeyed without question. Slowly, her breathing evened out, her tense, nervous pumps into Koharu's ass growing smoother, deeper.

"Oohh yes, Tsunade, that's it…" Koharu moaned softly.

Ryoku tried again, pushing forward. This time, his cock slipped deeper, like unlocking doors one by one. Inch by inch, until… he stopped. He wasn't even fully inside. "Huh?" he muttered aloud, baffled.

Squinting from the pressure, Tsunade offered an answer. "Some of us futanari have very shallow anal pathways. We tend to be the ones doing all the fucking… while people like Koharu, with deeper ones, generally get fucked."

The revelation floored Ryoku. But whatever lesson Tsunade was teaching vanished as his attention shifted to the sensation of her insides hugging his cock—tight walls squeezing down on him. "Unhgh…" he grunted, caught off guard.

"Ahh…" Tsunade moaned softly, her body molding to his shape. It was the biggest she'd ever taken.

Ryoku let a slow string of saliva drip onto his shaft, adding extra lube to ease the motion. As Tsunade's tight ring adapted to his intrusion, he began to rock his hips back and forth—slow, careful thrusts to avoid hurting her.

"Mmhmmm, yes, right there… That's it…" Tsunade whispered, breathlessly.

The sight of the Hokage—submissive, bent over, taking it from behind—while Koharu was getting the same from her was enough to make Ryoku feel like he could die happy. Each thrust loosened her further, the squelch of saliva and precum filling the heavy silence between their moans.

Time passed in a haze of sweat and sound until Tsunade began moving with him, pushing back. "Yes… fuck me, my dear Ryoku… FUCK me good!" she cried, hips bucking against him. Ryoku didn't hold back, tugging her hair as her fat ass clapped against his thighs. "Plap, plap, plap."

The room was chaos. Liquid puddles stained the floor. The air hung thick with musk and heat. Not a single person present looked remotely fit to attend a Kage Summit. Tsunade's hair was a mess from all the tugging, her tits spilling from her top. Koharu's thighs gleamed with juices running freely down her legs. It was carnage.

Ryoku knew they were running out of time, but instinct had fully overtaken reason. He was in the moment, and nothing else mattered. Sliding his hand down beneath Tsunade's ass, just above her balls, he found her clit. Three fingers rubbed it in a circular motion, as he mercilessly drove his dick into her ass with greater force.

Tsunade bit down on her lip, her hips meeting Koharu's with brutal slaps. "UGHMMMG! RYOKU, YOU'RE GONNA MAKE ME CUMM!!" she screamed, legs trembling violently.

As if perfectly timed to catch Tsunade at her limit, the conference room door swung open just as her juices exploded everywhere—spraying past Ryoku, droplets landing squarely in front of someone that should've never seen what was going.

The Mizukage.
