Vol 4 Chapter 56: Shin vs. Nina ☆

Previously on the story:

Shin had fallen into the trap set by the Alraune, Aster, and was driven into a lustful frenzy.

Following Aster’s command to “attack any village woman,” Shin lost control. However, instead of turning on the elves or his companions, he directed his instincts toward the monster before him. Acting purely on impulse, he relentlessly assaulted Aster’s breasts.

Overwhelmed by the human’s unexpected lust and the unfamiliar sensations of pleasure coursing through her body, Aster climaxed repeatedly until her consciousness faded into a blissful void.

◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇

Time passed.

Even after Aster had passed out from the overwhelming pleasure, Shin continued his relentless assault. Her unconscious body would occasionally twitch and jerk, as though trapped in a vivid, erotic nightmare.

The endless cycle of torment was broken only by a voice calling from the distance.

“Found you! Hey, Shin! Are you okay—wait, what the hell are you doing?!”

The voice belonged to Nina, the thief known as White Lightning. Her hair, with strands resembling twitching cat ears, bristled when she caught sight of Shin clinging to the Alraune’s chest. It rose as though on edge, almost like a warning signal.

Nina had been playing with the village children when their worries drew her here.

“Hey, hey! Shin onii-chan and Kaguya onee-chan are late, huh?”

It had been a while since Shin left, followed soon after by Kaguya. Concerned by how long they were gone, one of the children spoke up. Nina agreed it was unusual, and her mind raced, piecing everything together.

“Those two… They’re sneaking off to mess around, aren’t they!”

She imagined Kaguya leading Shin somewhere deep in the forest, out of sight, to give him her undivided attention. Nina herself would do the same if she were in Kaguya’s position—tease Shin until he made that sweet, helpless face.

“Good grief, those two… Fine. Hey, Alice! I’m gonna go bring Shin and Kaguya back, so watch the kids for me! And you brats, you’d better listen to your little nee-chan!”

“Okay!”
“Alice-chan, let’s play!”
“See you later!”

“Stop calling me ‘little’!” Alice pleaded, but Nina just flashed a mischievous grin, waved at them, and took off running.

She sprinted through the village, cloak fluttering and her chest bouncing.

“Heh, if they thought they could have fun without me, they’re wrong! Maybe I’ll tell Lena and see how they like that.”

She used her thief’s Detection Skill as she headed into the forest.

Before long, she found something far from her initial assumption.

“What the… is this…?”

It wasn’t Shin and Kaguya fooling around—it was an unsettling sight: several elf women lying unconscious, breathing steadily, and Kaguya tending to each one.

“H-hey… Kaguya?! What happened here?”

At first, Nina wondered if Kaguya had gone wild and attacked all these elf women herself, but she shook her head.

Kaguya, who was usually calm, spoke quickly, her composure fraying at the edges. She explained that the elves had been hit with an aphrodisiac mist, causing them to turn on Shin. Kaguya managed to knock them out with sleeping medicine, and Shin took off after the enemy.

“You’re kidding… This is still inside the village, right? Are these elves gonna be okay?”

Kaguya nodded.

“They’re safe, but I can’t leave them like this, so please go help Shin-sama. Take this—it might help if anything happens!”

Nina gripped the item Kaguya handed her.

“Got it. I’ll go!”

Shin was strong—she repeated that to herself as she ran off. Still, if the enemy was a woman, and if she had a big chest…

Worry gnawed at Nina’s thoughts, and she sped up. She cared about Shin—not just as a comrade, but as someone dear to her.

Eventually, she arrived at a bizarre scene: Shin pressing his face to the chest of a green monster—an Alraune.

At first glance, Nina thought Shin was being attacked. Yet it quickly became clear the Alraune was the one on the receiving end. Her eyes were rolled back, drool dripped from her mouth, and with every movement Shin made against her body, her head lolled lifelessly. She was clearly unconscious.

It looked as though Shin—who was always so passive—was now the one assaulting a woman.

“W-what the hell is going on here…?”

At least Shin seemed unharmed. But as relief settled in, Nina felt an uncomfortable, swirling emotion rise in her chest.

“Hey, Shin! Kaguya’s worried, so hurry up and get back!”

Her tone was slightly sharper than usual, tinged with frustration and something closer to misdirected anger. Her words reached Shin, as his head twitched slightly in response.

Without a word, he slowly lifted his face away from the Alraune’s chest. Moving with deliberate slowness, as if to tease, he turned his head toward Nina.

Nina found herself at a loss for words as she took in Shin’s appearance.

The gentle, timid smile he always wore was gone. His eyes were vacant, his mouth slack like a beast ready to devour its prey, and drool dripped from his lips.

He was aroused—so much so that he’d lost himself entirely. Remembering Kaguya’s explanation about the aphrodisiac mist, Nina quickly understood what had happened.

Then Shin’s gaze fixed on her. The Alraune had seemingly lost its appeal, and now he stared at Nina, someone important to him, with the hungry eyes of a predator locking onto its prey.

Under the weight of his uncharacteristic gaze, Nina stammered, “S-Shin?”

In response, Shin’s slackened mouth moved slowly.

“B-boobs… Boobies…♡”

It was a pitiful, beastly roar—if one could even call it that. Hearing it, Nina made up her mind.

“Oh… so that’s how it’s gonna be, huh?”

She muttered under her breath, raising her arms in preparation. A solid punch should knock him back to his senses. Maybe it would even dispel some of the frustration that had been gnawing at her since she saw him clinging to the Alraune.

Shin, in contrast, let his arms dangle loosely, exhaling steadily. He didn’t even bother taking a proper stance. His gaze, however, was fixed directly on Nina—more precisely, on the chest barely concealed by her skimpy tube top.

Without hesitation, he dug his heels into the ground and charged.

“H-he’s fast?! Damn it, you’re serious!”

The sound of Shin cutting through the air as he sprinted straight at her sent a chill down Nina’s spine. His speed, enhanced by support magic, was so extreme that even Nina, a thief renowned for her agility, could barely keep up with her eyes.

In the blink of an eye, he was upon her, his hands spread wide and ready to grope. Shocked by his raw power, Nina leapt to the right at the last possible moment, narrowly dodging his charge.

“Ugh! Damn it! A swordsman who’s faster than a thief? That’s just unfair!”

She rolled across the ground to absorb the impact and scrambled to her feet. Her frustration spilled from her lips as she glanced at where Shin landed.

Shin’s feet hit the ground hard, carving deep furrows into the earth as he skidded to a stop. The gouges left behind bore testament to his strength and speed.

Sweat dripping from her forehead, Nina realized just how wide the gap in their abilities was. She muttered bitterly, “I can’t win… can I?”

Though she often played the fool, Nina’s sharp instincts as a thief rarely failed her. Behind her carefree facade lay a pragmatic mind, keenly aware of reality. Her instincts screamed that there was no way she could win a physical confrontation against Shin.

“…Boobs… Boobies…♡”

Shin didn’t gloat or show any pride as he turned back toward her. He simply muttered nonsensically, his body swaying as if drawn by an invisible thread.

“…You’re right—I can’t beat you in a fight.”

If this were a battle of swords or magic, Shin would dominate completely. Nina wouldn’t have stood a chance—she would’ve been too busy running for her life to even counterattack.

But…

“…But when it comes to this kind of fight, I’m not losing to you. Not a chance.♡”

Her voice dripped with confidence as she spoke.

Then, with a soft tapun♡, she tugged down the already minimal fabric of her tube top, revealing her full, voluptuous breasts.

Her bare chest jiggled provocatively, funyun♡, as she swayed them from side to side, teasing him further.

“Mugyu♡… Tapun♡… Funyun♡…”

Tanned skin and supple breasts. The pink tips adorning them were as enticing as ripe fruit, exuding a charm that whispered sweetly to a man’s primal instincts. She shamelessly flaunted them, letting them bounce as she wore a lascivious smile.

“Hey there♡ Look at this♡ It’s your favorite bouncy, jiggly boobs♡ I’m not running, so… come and get them♡”

Nina swayed her chest, letting it jiggle enticingly, as though performing a seductive dance to lure Shin.

These were the breasts etched into Shin’s very instincts.

Breasts that had defeated him time and time again, rendering him helplessly pleasured.

Softness, warmth, elasticity—the miraculous blend of sensations that made them an undeniable wonder of the human body.

“B-boobs… B-boobs…”

“That’s right, boobs♡ Come on now, walk nice and slow toward me. Step to the rhythm of the jiggle~♡ One-two, one-two♡”

Shin, utterly fixated, approached in a trance-like state, his breath heavy. The swiftness and precision of his earlier movements were gone, replaced by a slow, unsteady gait as he inched toward the enticing fruit before him.

“That’s it, good boy♡ Just like that… these are the boobs you love so much♡”

Shin’s strength, his reasoning—none of it mattered. He was moving purely on instinct, and Nina had found the one way to control him.

Step by step, like a child learning to walk, Shin made his way closer until he stood directly before Nina, breathing heavily through his nose.

He was close enough to touch her, and his thoughts were entirely consumed by the breasts before him. All he wanted was to bury his face in them, to knead and squeeze them to his heart’s content.

Nina tilted her head at a playful angle, her eyes narrowing seductively as she smiled.

Her fingers moved deftly, squeezing, pressing, and emphasizing the lusciousness of her chest, drawing Shin’s gaze even deeper into her trap.

Finally, she whispered sweetly, “Pa-fu-pa-fu… let’s do it♡”

“Boobiiieeesss♡”

With a primal scream, Shin lunged forward, his face sinking into her ample chest with a soft pafun♡ and munyun♡.

The force of his embrace nearly toppled Nina, but she braced herself, catching him with her smaller frame and holding him steady.

Shin buried his face deeper, his lips and tongue exploring, his muffled sounds of pleasure filling the air. He moved against her chest with the same fervor he’d shown with the Alraune.

“Mmh♡ Squirm all you want—but once I’ve got you, there’s no getting away♡”

With a mischievous smirk, Nina tightened her grip, pulling his head firmly into her chest with just her right arm.

The pressure blocked his airways, making it difficult for him to breathe. Nina knew that if she applied too much force, Shin’s enhanced strength could break free. Instead, she focused on keeping it natural, letting her soft breasts steal his attention and gradually deprive him of air.

While doing so, her left arm moved discreetly, preparing for the final blow.

“Sorry, Shin… but playtime’s over. You lose♡”

Funyun♡ With a gentle parting motion, Nina’s breasts released Shin’s face momentarily.

Seizing the brief opening, she emptied the contents of a small vial—Kaguya’s sleeping potion—directly into his face as he took a deep breath. Then, she quickly pressed her chest against him again.

Shin’s body twitched violently as if overwhelmed by the pleasure, then went limp. His weight fell entirely on Nina.

“Whoa—ouch! Geez, you’re so heavy…”

She winced as she fell backward, her body pinned under Shin’s.

Shin, with his face nestled against her chest, no longer posed any threat. His breathing was soft and steady, and his eyes were closed in peaceful slumber.

Nina sighed in relief, stroking Shin’s hair while staring at the vial in her hand—the sleeping potion Kaguya had entrusted to her.

“Use this—inside is a sleeping potion I’ve prepared myself. If anything happens to Shin-sama, please use it!”

Although she had timed it perfectly, Nina couldn’t help but feel uneasy.

“Seriously, though… isn’t this stuff way too strong? What kind of ninja even makes something like this…?”

Relieved but slightly intimidated by Kaguya’s ingenuity, Nina allowed herself a moment to catch her breath.
