Steve awoke the next day with an excited grin. Today was the first step in their devious plan, the beginning of unraveling Natsuki’s carefully crafted facade. As planned, he handed Yuri the manga ‘Gushing over Magical Girl’, relishing in dark amusement as she discreetly slid it into Natsuki’s bag.
For the next two weeks, they behaved like nothing unusual was happening. During the day, Yuri and Steve continued their daily routines, engaging in mundane conversations and seemingly innocent activities. But when night fell, they shed their disguises and delved into the depths of depravity with increasingly twisted games of passion. The Literature Club meetings provided a convenient cover, allowing them to discuss mainstream literature while their minds buzzed with forbidden desires.
Even as Monika waxed about Fforde and Sayori lost herself in Pratchett’s Discworld, Steve kept a watchful eye on Natsuki. He noticed the subtle changes, the telltale signs that the poison was taking hold. Her initial annoyance gave way to a newfound openness, though he detected a feverish quality to her interactions now. Glassy stares, flushed cheeks, heavy breaths… all signs of the inner battle raging within her mind.
His clincher came when he caught her rubbing her thighs together while perusing one of those magic girl manga. A sly smile tugged at his lips. She was ready. Oh, so ready.
He whispered to Yuri, “Tonight, my dear. Invite Natsuki over for some pretense or another. The real fun is about to begin.”
Yuri’s heart pounded in her chest as she listened to Steve’s hushed instructions. It was finally happening, the culmination of their carefully orchestrated plans. After weeks of manipulation, Natsuki was ready to be lured in. The corrupting influence of the manga had taken root in her mind, and now it was all coming to fruition.
As the time for the Literature Club meeting grew near, Yuri discreetly observed Natsuki, fixating on the flush of her cheeks and the glazed look in her eyes. There was a frenzied intensity to her actions now, an evident restlessness that spoke volumes.
When the meeting ended, Yuri approached Natsuki with feigned casualness. “Hey, Nats? I was wondering if you wanted to come over tonight. My parents are out of town, and I could use some company.” Her tone was light and airy, concealing the dark excitement coursing through her veins.
Natsuki hesitated briefly, nibbling on her bottom lip as she glanced at the manga in her bag. The internal struggle was palpable, her body vibrating with indecision. But then something seemed to snap – a decision made, a line crossed. “I…sure, I can come over.” Natsuki’s voice quivered slightly.
Yuri smirked with anticipation. “Perfect. I’ll see you tonight, then.”
As she walked home, Yuri was practically buzzing with excitement. Every step brought her closer to Natsuki, closer to the moment when they would unleash her deepest desires. She could hardly contain herself, eager to see how Natsuki would react and crumble under the weight of her repressed lust.

Later that evening, at Yuri’s apartment, Steve turned to her with a sly grin. “It’s showtime. Our guest will be here soon, and I can’t wait to see her transformation. Yuri, my dear, it’s time for you to take center stage.” He chuckled darkly. “You’ll be the vulnerable magical girl desperate for our guest’s attention.” His eyes roamed over her authentic and perfect costume.
Gathering some items, he expertly bound Yuri’s limbs, stripping away her freedom. The familiar motions brought a smug smile to her lips – they had done this dance before. When he finished, Yuri was sprawled out on the couch like a tempting invitation, exuding an aura of artificial vulnerability.
“When she arrives, just greet her and welcome her inside. Then let nature take its course.” Steve placed a whip beside her, setting the stage for their guest’s performance. “We both know how much you enjoy what she does to you. But pretend to resist at first. Put on a show.” He gave her one last fiery kiss before disappearing into the adjacent room, leaving Yuri ready to play her role as the main attraction. The night was young and full of forbidden possibilities.
Yuri’s breath caught in her throat, her blood singing with anticipation. This was it – the moment they had been building up towards. The edge where Natsuki’s innocence would crumble and her darkest desires would be dragged into the light.
As the doorbell rang, Yuri called out with a practiced expression of wide-eyed innocence, “Come in, Natsuki!”
The door creaked open, and Natsuki stood there. “H-hey, Yuri. Thanks for inviting me over.” Her voice trembled as her hands fidgeted with her skirt.
“Of course, Natsuki! I’m so glad you’re here.” Yuri’s tone oozed with sweetness, entirely at odds with the gleam in her eyes. “I have something special planned for us tonight. A surprise of sorts.”
Natsuki walked into the living room and was taken aback by the scene in front of her – Yuri lying on the couch in a revealing magical girl outfit bound by ropes. Yuri watched intently as Natsuki’s face showed a mix of shock, confusion, and hunger. The hunger quickly overtook her other emotions, causing her pupils to dilate as she took a hesitant step forward.
“N-Natsuki…” Yuri stuttered, trying to inject fear into her voice. “W-what are you doing?” But Natsuki kept advancing, a predator stalking her prey, and Yuri could only lie in wait, quivering with perverse delight.
Steve watched with satisfaction from his hiding spot as Natsuki’s true nature emerged. She pounced on Yuri with ferocity from years of suppressed desires and denial. In Natsuki’s world, there was only one focus – the sight of Yuri bound and vulnerable, an innocent figure begging to be devoured. A primal urge stirred within her, and her hands shook as they roamed over Yuri’s body, mapping every curve and contour of the alluring magical girl before her.
Yuri gasped at Natsuki’s touch, feeling shivers run down her spine in response. She shook her head and squeezed her legs tightly together, pretending to resist. But her body betrayed her eager arousal: stiff nipples and a wet spot forming between her tights.
Natsuki buried her face between Yuri’s breasts, taking in her scent and feeling dizzy with desire. Her hands grew bolder, slipping beneath the thin fabric of Yuri’s outfit to explore the warm flesh underneath. “Yuri…” she moaned almost pleadingly, unable to fully articulate the depths of her hunger. So instead, she let her actions speak for her, groping and pinching the helpless body before her, and Yuri’s delicious writhing only inflamed Natsuki’s lust further.
Lost in a haze of twisted bliss, Natsuki barely registered the sound of approaching footsteps behind her – Steve emerging from the shadows. His dark chuckle sent shivers through her body. Walking over to Natsuki with a smirk, Steve tossed her a condescending smile. “Having fun there, Natsuki? Why don’t you try this, hmm?” He taunted as he handed her the whip.
Sitting down on the couch next to Yuri, he rolled her onto her stomach, exposing her tight rear as an enticing target for Natsuki’s newly awakened sadistic urges. “Go on then, show her what you’ve got,” Steve growled as he unzipped his pants and pushed his cock towards Yuri’s face, forcing it into her mouth.
Natsuki’s heart raced as she took the whip in hand, caressing its leather braids with reverence. In her grip, it pulsed with dark promise. With a tentative flick of her wrist, she tested its weight, the crack of leather echoing through the room like cries of angels in Natsuki’s ears.
Emboldened by Steve’s cruel encouragement, Natsuki moved to hover over Yuri’s bound form, drinking at the sight of her acquiescent body. The lewd display of Yuri’s upturned ass and quivering flesh urged Natsuki to unleash her pent-up desires. With a snap of her wrist, she delivered the first strike with the whip – a loud pop that left a crimson welt in its wake. The mark indicated possession and sent a thrill through Natsuki. Realizing the power she held in her hands, she fell into a brutal rhythm, painting Yuri’s backside with stripes of raw red.
Yuri’s cries echoed in response to each lash, her voice muffled by Steve’s cock between her lips. Tears flowed down her cheeks, a mixture of pain and pleasure overwhelming her senses. Natsuki, lost in a haze of desire, couldn’t help but notice Steve assertively gripping Yuri’s head and thrusting into her mouth without mercy, only fueling Natsuki’s own desires even further.
With one last strike, Natsuki threw the whip aside and knelt between Yuri’s legs. She traced the marks left behind on Yuri’s skin, marveling at the trembling form before her. Her fingers trailed down to the slick folds between Yuri’s legs, tasting the evidence of her arousal. Slipping two fingers inside, Natsuki began a slow, deep delve into Yuri, reveling in the tight clench of her walls around the intrusion.
Steve observed with delight as Natsuki fingered Yuri’s wet cunt, eagerly savoring every moan and cry that escaped from her lips. He pulled his throbbing cock out of Yuri’s mouth, leaving her gasping and drooling on the sofa. He sauntered Natsuki, towering over her crouched figure.
“You’re doing wonderfully, Natsuki. Yuri is all yours now. Take her to new heights of pleasure,” he purred, placing his hand over hers. Guiding her frantic movements deeper, he urged her to push past any limits until her entire fist was buried inside Yuri’s quivering hole, the wet squelches serving as a soundtrack to their debauched performance. The walls of Yuri’s inner core yielded like warm butter around Natsuki’s hand with each forceful thrust. Pushing herself beyond any boundaries of decency or control, Natsuki could feel Yuri’s anguished cries and excited moans reverberating through her arm. Each one a bitter melody of pain and pleasure, yet she couldn’t stop.
Satisfied with Natsuki’s progress, Steve stepped behind her, pulling down her skirt and panties before holding his pulsating cock onto her dripping slit. With a primal grunt, he drove himself deep inside her, pushing her face-first into Yuri’s twisting body, pulling her out of her thoughts and into a state of primal fear and arousal. She let out a cry that mixed pain with ecstasy as he thrust himself deep within her trembling body. Pinned between Steve and Yuri, their bodies moving in an almost grotesque dance of agony and ecstasy, Natsuki felt every point of contact – the slick slide of skin against skin, the ache of strained muscles, and the pounding of three hearts in a chaotic rhythm. She was at the center of a storm, a whirlwind created by her actions.
Yuri’s moans and Steve’s grunts filled the air like a macabre soundtrack to their debauched waltz. Natsuki writhed against them, caught up in the chaos, feeling every thrust of Steve’s relentless cock driving her further into depravity. At the same time, Yuri’s walls clenched around her hand, silently begging for more.
She knew there was no turning back from this level of corruption; it was her destiny, her proper form – a puppet dancing on strings pulled by lust and perversion, forever enslaved to the twisted desires of those around her and her own. And although she couldn’t deny the depths of darkness she had sunk to, she reveled in it, intoxicated by the forbidden power surging through her veins.
For a while, all that could be heard in the room was the wet noise of flesh slapping against flesh and their passionate cries. Yuri was lost in an agonizing ecstasy, driven higher and higher by Natsuki’s relentless fisting. Natsuki herself was consumed by desire, switching between being dominated and dominant. Their voices rose in harmony as they raced towards release.
“Come!” Steve roared as he thrust one final time into Natsuki. He spilled his sinful seed deep inside her, filling her with his essence. Natsuki and Yuri screamed together as they reached their climax, creating a symphony of pleasure that echoed off the walls.
Exhausted and satiated, they collapsed into a tangle of limbs and sweat. The scent of sex hung heavily in the air, a constant reminder of their sinful union. As Steve looked upon the two bodies before him, he felt a sense of satisfaction—another triumph in his campaign of corruption, another soul claimed by the darkness.
But he knew this was just the beginning; with Yuri and Natsuki now fully aware and freed by their twisted desires, it would only be a matter of time before Monika and Sayori also fell under his spell.
*
Steve released Yuri from her bonds and pulled both girls into his arms. “Yuri, Natsuki, tell me how you feel?”
As she lay amongst the tangle of limbs and through the haze of post-orgasmic bliss, Natsuki became aware of a new truth – she was changed, transformed by the depths of depravity she had embraced. There was no going back to the innocent girl she once was; there was only moving forward as a willing fellow to her most primal desires.
Lifting her chin with defiant pride, Natsuki found her voice, her words spilling forth in breathless confession: “I feel … alive. Like I’ve been reborn in the crucible of sin. Every part of me aches to explore the depths of depravity, to wallow in the filth of my corruption.”
Yuri, likewise, roused from her stupor, amber eyes glazed with the aftershocks of rapture. She turned to Natsuki, a reverent smile gracing her lips as she caressed her flushed cheek: “You were amazing, Natsuki. Your touch sent me spiraling to the heavens, an exquisite mingling of pleasure and pain.”
Natsuki’s heart soared at Yuri’s words, and a sense of belonging and purpose suffused her very being. Together, they had transcended the shackles of societal norms. With Steve’s guiding hand, she knew there was no limit to the depraved delights that awaited them.
Steve’s triumphant smile sent shivers down the girls’ spines as he pulled them close and pressed his lips against theirs. They clung to him, basking in the aftermath of their forbidden bliss, their bodies still trembling with pleasure.
“Excellent work, my depraved girls,” he purred, his voice a sinister caress. “You have shown great potential for sin, and I intend to see it fully realized. But our work is not yet finished.”
Releasing them from his embrace, he strolled over to the window and gazed out at the slumbering town below. His eyes narrowed as he plotted their next move, and the cogs of malevolence turned in his mind.
“Sayori will be the next one to fall,” he declared, reveling in the room’s anticipation. “Behind her sweet, innocent facade lies a deep well of repressed desires just waiting to be unleashed. And unleash we will them.”
He turned back to Yuri and Natsuki with a question. “I have some ideas on how to break through her wholesome exterior and let her true nature emerge. But I am curious to hear your thoughts as well. What are her weaknesses, and how can we exploit them?”
Natsuki’s heart raced at the mention of Sayori, a mix of excitement and dread swirling in her stomach. The thought of putting her friend through the same twisted initiation she went through filled her with a twisted thrill, even as guilt tugged at her conscience. But the lure of watching Sayori’s descent into debauchery was too strong, drowning out any lingering feelings of remorse.
Natsuki mused, “Sayori’s weakness is her desire to make everyone happy and feel like she belongs with her friends. If we frame our actions as necessary for the growth and strengthening of our friendship, she will do anything to please us. We can use her need for approval against her, leading her toward increasingly sinful acts.”
Yuri nodded in agreement, a glint of hunger in her eyes that matched Natsuki’s. Together, they brainstormed ideas with growing enthusiasm, their voices rising excitedly as they painted a vivid picture of Sayori’s downfall. Steve listened intently, a smile playing on his lips as he reveled in their twisted plans.
By the time they were finished, a detailed plan for corrupting Sayori lay before them, a carefully crafted map to shatter her innocence. Natsuki’s heart raced with anticipation, fueled by the adrenaline of their devious collaboration. She knew she should feel guilty for betraying her friend’s trust, but all she felt was a perverse sense of pride and an insatiable hunger to see their plans come to fruition.
Steve raised an eyebrow, impressed by the girls’ devious plan. It aligned perfectly with his wicked intentions. “That’s clever,” he said, his voice tinged with approval. “Exploiting Sayori’s desire to please is a foolproof strategy. And with her naivete, it will be even easier to manipulate her. And since we’re the Literature Club, we’ll execute our plot with a book: ‘Blue Moon Rising’ by Simon R. Green. It starts with a prince and a talking unicorn saving a princess from a dragon. Perfect for Sayori, no? The story turns darker later, but that won’t matter. Green’s writing style is light and humorous, just like the Pratchett novel Sayori is currently reading. She’ll enjoy it on the surface.”
After a dramatic pause, he continued, “But Green is skilled at incorporating subtle innuendos and hidden meanings. Where others may use five sentences to convey a message, he does it in one – but the reader must interpret between the lines and use their imagination. Not exactly Sayori’s strong suit.”
He met the girls’ eager gazes. “We’ll invite Sayori for a sleepover and read this book together. She’ll laugh at the unicorn’s jokes and root for the prince. But we’ll dig deeper, analyzing the underlying messages and symbolism. Sayori will feel left out, struggling to understand everything as her mind tries to keep up. Eventually, she’ll shut down and go into autopilot.”
A smile curved his lips as he revealed their final act. “And that’s when we’ll put on our sexual performance. Desperate to fit in, Sayori will instinctively join in with us. And then she’ll be ours.”
Natsuki felt a thrill run through her body as she absorbed Steve’s plan’s devious details. It was perfectly tailored to exploit Sayori’s naivete and desire to please. She could already imagine her friend’s confusion, followed by the realization of their true intentions – and finally, her surrender into the twisted pleasure they were offering.
Natsuki grinned widely, “I’m ready. Sayori won’t know what hit her until she’s fully immersed in sin. This is going to be the most deliciously devilish sleepover ever.”
Beside her, Yuri nodded in agreement. She had been positively glowing since their initiation, reveling in the chance to corrupt another unsuspecting soul. Dark fantasies of molding Sayori into a sex-crazed slut like herself danced through her mind, each one more depraved than the last.
“If we’re going to make Sayori ours,” Yuri purred with a low and secretive voice, “we need to push her boundaries from the start. We can use some of the techniques we’ve learned – shocking her with raw sexuality, then guiding her through the haze of pleasure towards corruption.”
Natsuki’s breath quickened at the thought, her pulse racing with memories of her intense initiation. “Agreed. We should have some toys and tools ready, anything that will keep Sayori off balance and obedient to her own and our desires. By the time we’re done with her, she’ll be addicted to depravity and begging for more.”
Their minds were already spinning with possibilities, scheming to lead Sayori down the same dark path they had walked. The thought of sharing this twisted pleasure with their friend and witnessing the complete destruction of her innocence sent a surge of excitement through their veins. Unable to contain themselves any longer, Yuri and Natsuki reached out for Steve and pulled him back onto the couch with sultry smiles. The night was still young, and there were plenty more depraved activities for them to explore together.
