“So, what if your charming pen pal turns out to look like Quasimodo?”
“I have his picture! Besides, it’s not like we’ll ever actually meet. He’s serving life.”
Your friend gaped at you, her eyes widening in disbelief.
The conversation had begun with your usual letter-writing ritual. What had once been a simple hobby had evolved into an infatuation with a man labeled as one of the world's most dangerous criminals. Despite his reputation, his letters had been nothing but kind, making your heart flutter with each new page. His picture revealed a ruggedly handsome man, his body adorned with tattoos that hinted at a dangerous past.
You had told your friend about him almost a year ago. Predictably, she responded with trepidation, urging you to choose a less notorious correspondent.
“He’s still a person,” you’d argue. “Even the most hated need love too. And what harm could he do if he never knows where I live, let alone what I look like?”
However, his latest request had unsettled you both. He wanted a picture of you, something to remember you by during lonely times. Your friend was livid when you mentioned it.
“You cannot send him a picture! What if he has friends on the outside? I refuse to become a target because of your bad decisions!”
You laughed it off, continuing to write a diplomatic yet affectionate refusal. Your friend, exasperated, finally sighed in defeat.
“Well, enjoy writing to the serial killer. I’m staying at my boyfriend’s place for a while. If he gets out and comes after you, call the police first, then me.”
You reassured her with a laugh, promising to be cautious. She hugged you tightly before leaving. Neither of you noticed the grey car parked across the street, its presence having become so familiar it was easily ignored.
The following evening, a knock at your door startled you. Expecting your friend, you were puzzled to find no one there. Just a box.
With a mix of excitement and dread, you approached the door. The box bore a note in handwriting you recognized instantly:
*Such a beautiful home. I thought you would enjoy a little gift from the other side…*
Your anxiety surged. You scanned the empty, unnaturally quiet street before retreating inside. The flickering streetlight across from your home seemed dimmer than usual, casting eerie shadows. A rustle in the bushes sent you scurrying back inside, locking the doors and setting the alarm with trembling hands.
The box sat ominously on your coffee table. Despite your curiosity, fear kept you from opening it. Instead, you holed up in your room, hoping sleep would come despite the dread gnawing at you.
In the dead of night, you jolted awake to the sound of metal scraping against metal. Someone was inside your home.
Determined not to fall into the typical horror trope of investigating, you stayed put. But then you heard it—footsteps, slow and deliberate, ascending the carpeted stairs.
Panic gripped you. Clutching the bat you kept in your closet, you listened as the intruder approached. The door across the hall creaked open, and you steeled yourself for the worst. But then you recognized the sounds—muffled giggles and a familiar voice.
Relief washed over you. Your friend had returned, and apparently brought her boyfriend. You set the bat down, heart still racing, and fell back into bed, the adrenaline finally giving way to exhaustion.
In the morning, you would face the box and the mysteries it held. For now, you allowed yourself to sink into the comfort of your bed, hoping that sleep would bring a respite from the turmoil of the past few days.
The morning light filtered through the curtains, casting a warm glow on your bedroom. Despite the terror of the previous night, you felt a strange sense of calm as you padded downstairs. The box still sat on the coffee table, its presence a reminder of the eerie note and the mystery it held.
Taking a deep breath, you sat on the couch and gingerly lifted the lid. Inside, nestled in a bed of luxurious velvet, was an object that took your breath away. It was a stunningly crafted necklace, the centerpiece a large, gleaming sapphire surrounded by intricate filigree work in white gold. The piece was elegant, expensive, and utterly out of place for something sent from a prison.
You lifted it gently, the gem catching the light and casting tiny rainbows across the room. For a moment, the sheer beauty of the necklace overshadowed your fear. How could something so exquisite come from a man behind bars?
Elated but wary, you turned the necklace over in your hands, inspecting every detail. It was flawless, and the craftsmanship was impeccable. This was no ordinary gift.
Your mind raced. How did he manage to send something so extravagant? More importantly, how did he know your address? You felt a shiver run down your spine as you recalled your friend's words: *“What if he has friends on the outside?”*
The realization hit you hard. He must have outside help. Someone capable of acquiring such a piece and delivering it to your doorstep. Your elation was quickly replaced by a deep sense of unease.
How long had he known where you lived? You thought back to the grey car that had been parked across the street. Was it connected? Had you been watched?
You set the necklace back in the box, hands trembling. The beauty of the gift now seemed tainted by the sinister implications. Your friend's warnings echoed in your mind: *“I am not going to die because of your bad decisions!”* You couldn’t ignore the danger any longer.
Reaching for your phone, you dialed your friend’s number. She answered on the third ring, her voice groggy with sleep.
“Hey, it’s me. You were right. We need to talk.”
Later that day, your friend arrived, her face a mix of concern and frustration. You showed her the necklace, and she gasped.
“This is... gorgeous. But it’s also terrifying. How did he send this?”
“I don’t know,” you admitted, your voice shaking. “And I don’t know how he found my address.”
She paced the room, glancing nervously out the window. “We need to call the police. This is beyond creepy.”
You nodded, knowing she was right. The thrill of your pen pal had turned into something dangerous, something that required more than just caution. As you picked up the phone to dial the authorities, you couldn’t shake the feeling of eyes on you, the sense of being watched. The beautiful necklace now felt like a heavy weight, a symbol of the peril you had unwittingly invited into your life.
As you waited for the police to arrive, you couldn’t help but wonder about the man who had written such kind letters. Was he truly as dangerous as they said, or was there more to the story? Either way, you knew you couldn’t continue the correspondence. The price of your curiosity had become too high, and your safety was worth far more than any thrill or beautiful gift.
A few weeks had passed, and your friend continued to stay with her boyfriend, feeling guilty for leaving you alone but too scared to return. She called you every day, ensuring you were unharmed and feeling as well as could be expected. The police had stationed an officer outside your house during those weeks, but with no further incidents, they eventually recalled the officer. They advised you to call if anything came up, assuring you they would do their best to keep you safe. You had downplayed the threat, omitting any mention of your pen pal. Had they known the full extent, they might have placed you under witness protection.
Unfortunately, the eerie calm was shattered today.
The grey car had returned, and this time, you could make out the driver. He bore a stark resemblance to the picture you had seen of your pen pal, the world’s most dangerous criminal, now sitting outside your home, watching and waiting. But for what? What did he plan to do once you were alone?
You couldn't call out from work again, needing to maintain some semblance of normalcy. Steeling yourself, you put on your best intimidating face and walked to your car, though you felt more like a deer caught in headlights. Ignoring the piercing, watchful eyes of the man was harder than you imagined, but you managed to get into your car and drive away.
You knew it was foolish to drive to work, thinking he might follow you, but if he knew your address, he likely knew where you worked. At least at work, you'd be surrounded by people and security personnel. If he tried anything—which you doubted he would in such a public setting—there would be help nearby.
The day dragged on, dread gnawing at you. Your focus was shattered, and your supervisor almost reprimanded you until they realized how shaken you were. They backed off, giving you space to regain your composure. HR knew something was seriously wrong but couldn’t disclose details to anyone else, offering you a temporary reprieve.
But this day was particularly harrowing, and you barely made it through. As the workday ended, you practically sprinted to your car, seeking the relative safety it offered while there were still people around.
Home was a different story.
You entered, not realizing the door had been unlocked until you were already in the living room. Shock, dread, and fear flooded you as you saw him there, seated on your sofa.
He was casually examining a picture of you with your friend, family, and your old pet. He looked content, as if he belonged there, as if he were truly at home.
Panic surged. You wondered what he could do to you in such close quarters. Thick walls muted sounds from neighboring homes; no one would hear you in time. You felt paralyzed, unsure of what to do if he made a move.
He shifted his position, dropping one leg and crossing the other, all the while holding your gaze. He took in your presence, the real you, not just the image he had studied. You were no longer a picture, but flesh and blood, standing before him.
“Nice to meet you, [Your Name].”
You had never told him your real name, only an alias. Somehow, he had discovered your true identity, just as he had found your address.
“I hope you don’t mind my intrusion. I couldn’t resist, especially after a month of silence from you. I noticed you called the police. I'm quite impressed that you managed to keep my presence in your life a secret.”
You trembled, tears starting to well in your eyes and trickle down your face.
“Ah, don’t cry. I’m not here to harm you. What I have in mind will be much more pleasurable. For both of us.”
His words chilled you to the core. The beauty of the necklace, the allure of his letters, all seemed like a distant dream compared to the present reality. You stood frozen, unable to move or speak, as he smiled at you, his intentions shrouded in menace and mystery.
“I-I…”
The tears began to slow, your breath evening out as a semblance of calm started to return. He watched you closely, giving you a moment to dry your face and find the words that had eluded you.
But silence persisted. Your thoughts were in disarray, still grappling with the reality of his sudden presence. He seemed to sense your inner turmoil, knowing you needed time to process the situation. As he approached, his imposing figure loomed over you, each step bringing him closer.
Realizing his intent, you instinctively retreated, but his long strides easily closed the distance. Your back met the cold, unyielding wall, trapping you. You wished you could tear it down, burrow into an indestructible sanctuary, and escape the nightmare your life had become.
His proximity was overwhelming, a blend of menace and fascination, as you stood frozen, unable to tear your gaze from his. The intensity of the moment hung heavy in the air, a storm of emotions threatening to consume you both.
He continued to close the distance, his presence suffocating yet electrifying. You could feel the heat radiating from his body as he drew nearer, until he was mere inches away. He raised his arms, placing his hands on the wall on either side of your head, effectively caging you in. The scent of him, a mix of cologne and something distinctly male, enveloped you.
"Is this what you like?" he asked, his voice a low, tantalizing murmur. His eyes bored into yours, searching for a reaction.
Your breath hitched, the proximity overwhelming your senses. The thrill of fear and an unexpected surge of excitement coursed through you, leaving you dizzy and unable to respond.
"Tell me," he continued, leaning in even closer, his lips brushing against your ear. "Is this what you've been waiting for?"
The intensity of his gaze, the warmth of his breath, and the sheer force of his presence made it hard to think, let alone speak. You were caught in a whirlwind of emotions, your mind a chaotic mix of fear, confusion, and a strange, unwelcome attraction. His dominance was intoxicating, leaving you both terrified and inexplicably drawn to him.
His hands remained on the wall, trapping you, as his eyes continued to hold yours captive. The room seemed to shrink around you, the air thick with unspoken tension. In that moment, you realized you were at his mercy, and the realization sent a shiver down your spine.
The intensity in his gaze didn't waver as he spoke again, his voice a silken whisper. "Why don't you show me around? I'd like to see more of your home."
Your heart pounded as you nodded, feeling compelled to comply. Slowly, he dropped his hands from the wall, giving you a semblance of freedom, though his presence still dominated the space. He gestured for you to lead the way.
With trembling steps, you walked towards the staircase, feeling his eyes on you, a constant reminder of the danger and allure he embodied. The transition from the living room to the upper floor was surreal, the normalcy of your home tainted by his dark presence. Each step up the stairs felt like a journey deeper into an inescapable labyrinth.
You reached the top of the stairs and paused, glancing back at him. His expression was unreadable, but a faint, almost predatory smile played at his lips. You hesitated for a moment before pushing open the door to your bedroom.
"This is my room," you said softly, stepping inside.
He followed, his tall frame filling the doorway before he moved to the center of the room. He looked around, taking in every detail. The room, once a sanctuary, now felt exposed and vulnerable.
"Show me more," he instructed, his voice firm yet oddly gentle.
You led him to the adjoining bathroom, your hands trembling as you opened the door. The bathroom was small but neat, the shower glistening under the overhead light. He inspected it briefly, then turned back to you, his eyes locking onto yours.
"This will do nicely," he said, his tone casual but with an undercurrent of something more.
Your mind raced, the reality of the situation pressing down on you. "What do you want from me?" you managed to ask, your voice barely above a whisper.
He stepped closer, reaching out to gently brush a stray lock of hair from your face. "For now, just your cooperation. Tonight is just the beginning. After the night's activities, I might need a place to clean up."
His words sent a shiver down your spine. The ambiguity of "activities" left your mind reeling with possibilities, each more terrifying than the last. You found yourself nodding, unable to do anything else.
"Good girl," he murmured, his hand lingering on your cheek. "Now, let's make the most of our evening together."
His touch was both reassuring and sinister, a stark reminder of the control he wielded over you. “Take this off…”
You were shocked, appalled even, at such a request from a man you barely knew, despite the intimacy of his letters, the truths he shared, his truth.
You hesitated, glancing up at him with a mix of trepidation and a spark of rebellion.
He smirked slightly, as if he had anticipated your resistance. His hand reached out, but you scurried backward, clutching onto what felt like the last vestiges of your dignity.
He wasn’t taking no for an answer, not from someone who had shown him such genuine kindness, such unguarded affection for the first time in decades.
It dawned on you just how monumental a mistake that kindness had been.
As you stood there, frozen in your shock, he moved swiftly. In an instant, he had closed the distance between you, his strong hands seizing your blouse. The fabric bunched under his grip, the force of his hold sending a jolt through you.
“Don’t fight it,” he murmured, his voice a velvet threat. “You and I both know this was inevitable.”
His words hung heavy in the air, mingling with the palpable tension that seemed to throb between you. His touch, firm and unyielding, ignited a tumult of emotions within you—fear, defiance, and a disturbing undercurrent of something you couldn’t quite name.
“You think you can just come into my life and—” your voice faltered, the defiance wavering under the weight of his gaze.
“I don’t think, I know,” he interrupted, his tone commanding and confident. His eyes, dark and intense, bore into yours. “You invited me in with every letter, every secret you shared. This connection we have—it’s real. And now, it’s time to face it.”
Your breath hitched as he pulled you closer, the proximity making your heart race. The air between you crackled with an undeniable energy, a mix of danger and an inexplicable pull that left you both terrified and entranced.
“You’ve got me all wrong,” you whispered, desperation creeping into your voice.
“No,” he replied, his grip tightening ever so slightly. “I’ve got you exactly where I want you.”
His words sent a shiver down your spine, the reality of your situation crashing over you. The walls of your sanctuary seemed to close in, the room shrinking as his presence dominated. You were caught in his web, and the more you struggled, the more entangled you became.
With a final, firm tug, he brought you even closer, his breath warm against your skin. “Let’s see how this night unfolds,” he murmured, a promise and a threat woven into his words.
In that moment, you realized there was no escape. You were his, for better or worse, and the night was just beginning.
His deft hands worked quickly, yet with a surprising gentleness, as he pulled at your blouse. He was careful, mindful of not tearing buttons or threads, his touch respectful in its slow haste to undress you. Each movement seemed deliberate, as if he were savoring the unveiling of your skin, as if he knew the value of each delicate inch.
Once your clothing lay discarded, you stood before him in just your bralette and panties, exposed yet somehow still veiled in mystery. His eyes roamed over you, taking in the sight of a woman—a vision of beauty that left him breathless. He drank in every curve, every line, every delicate feature, his gaze lingering on each detail as if committing them to memory.
He had seen countless women in his lifetime, but none had captivated him quite like you. There was something about you, something ineffable and intoxicating, that drew him in, leaving him hungry for more.
In that moment, as you stood there before him, vulnerable yet unyielding, he realized just how much he craved you. And he knew, with a certainty that bordered on obsession, that he would stop at nothing to possess you completely.
You knew that begging would likely be futile, so you chose silence instead, allowing your gaze to wander anywhere but at him and what he was doing. But he seemed to revel in being watched, his ego swelling as he unveiled each layer of your clothing.
His touch was insistent as his index finger and thumb grasped your chin, forcing your gaze to remain solely on him. You felt a surge of defiance rise within you, but it was quickly quelled by the intensity of his gaze.
With practiced ease, he removed your bra, followed by your panties. The air between you crackled with tension as he exposed you completely, and you couldn't help but feel exposed and vulnerable under his scrutiny.
A low groan escaped him, barely audible but unmistakable. It was a sound of longing, of desire unleashed after years of confinement. You realized then just how long it had been since he had seen a living, breathing woman, and the thought sent a shiver down your spine.
You stood there, naked and exposed, feeling his eyes on you like a physical touch. There was something primal in the way he looked at you, as though he were seeing you for the first time, drinking in every curve and contour of your body.
You tried to maintain some semblance of composure, but it was difficult under his relentless gaze. You felt stripped bare, not just of your clothing but of your defenses, your vulnerabilities laid bare before him.
As he stepped closer, the heat of his body enveloping you, you knew that there was no turning back. The night stretched out before you, a vast unknown filled with equal parts fear and fascination. And as he reached out to pull you closer, you couldn't help but wonder what other surprises lay in store.
Your cheek pressed into the cold, quartz floor of your bathroom, every nerve ending alive with sensation. You could feel the weight of him behind you, his eyes drinking in the sight of your rear pressing against his hips. His blazer, shirt, and pants had been discarded, leaving him in just his boxers. Despite the fabric that still separated your bodies, you felt everything from him—his warmth, his strength, his desire.
He had positioned you in a neat arch, your body stretched taut, every muscle straining against the confines of your own submission. His command was clear: remain still, hold that position until he was ready to take you further.
You obeyed, every fiber of your being thrumming with anticipation and fear. The cold floor beneath you was a stark contrast to the heat that radiated from him, and the sensation only heightened your awareness of every touch, every breath that brushed against your skin.
Time seemed to stand still as you waited, your body poised on the precipice of something unknown. You could hear the steady rhythm of your own heartbeat, a counterpoint to the electric tension that hung heavy in the air.
And then, without warning, his hands were on you, tracing the contours of your body with a touch that sent shivers down your spine. His fingers were skilled, mapping every curve and dip with a precision that left you breathless.
You felt him shift behind you, his body moving with a fluid grace that belied the strength coiled beneath his skin. You were afraid of the movement, wanting to look behind you to see what exactly he was doing. And when you felt the tip of him nearing your heat, you redacted the beautiful arch he helped you to create for him and tried to squirm away.
Before you knew it, he had your hair twisted in his hand, pressing your head painfully further against the floor, his breath fanning over your ear. “Move again… and I will crack your skull over this floor and with this treasure I’ll summon something worse than death for you.”
And then, with a suddenness that stole your breath away, he entered you, filling you completely with a single, powerful thrust.
The sensation was overwhelming, a flood of pleasure and pain that threatened to consume you. You bit back a gasp, your body trembling with the effort to remain still as he took you further, deeper into the abyss of his desire. He was much too large to enjoy, your stretched muscles struggling to comprehend the intrusion.
And as he moved within you, each thrust driving you closer to the edge of oblivion, you realized that there was no turning back. You were his, body and soul, caught in the grip of a passion that threatened to consume you both. And in that moment, as he claimed you as his own, you surrendered to the darkness that beckoned, knowing that there was no escape from the depths of his desire.
By the time he was finished, you had orgasmed nearly six times. The final was barely an orgasm, he had edged you and slapped your ass. Breathy laughs finding your ears and somehow you felt yourself able to share his laughter. Your cunt clenched against his twitching length, a feeling he relished in.
Just when you thought he was finished, he pushed your legs apart as far as they would go, nearly into a split, pressing himself further into you, impossibly deeper. Your eyes bulged, hips tightened and your cunt contracted against his deep-seated length once more, your cervix contracting and relaxing in slow bouts against his tip. He lifted your hips, allowing him a new arch, fresh angle, and an even deeper reach.
You wanted to sob, to beg him to stop, but you also wanted to see what he would do in this position.
He reached one hand in front, taking your neck into his possession and he pulled back just enough to keep you stationary and choke you slightly at the same time, the angle would do the rest.
And slowly, he pulled back, allowing just the tip to remain before he thrusts intensely inside of you, pressing against the spot he knew would drive you insane.
And you cursed him, screaming out all sorts of obscenities and lewd things as he continued to abuse the same spot. His girth squeezed in and out of you with much effort, the tightened feel of your cunt in this position was the one thing that kept him grounded, eyes drawn into a focus on your connected bodies.
He had cum so many times and this position had him dangerously close to blowing his load again, but he held back just enough. He wanted to cum with you again.
Increasing his speed, he pushed and pulled inside your pussy, watching as it sucked him and pushed him out simultaneously.
“S’kunaaaa… Fuuuccckkk! Pl-please!”
He knew what you were begging for, screaming out his name for. And he was so close to giving it to you. He had to give you what you wanted since you had been so obedient for him all night. He was nearing his end, bringing his free hand down to your clit and rubbing dangerous circles and odd shapes into it, nearly ritualistic in his methods and just he groaned his approval, you squirted. Full-body quakes erupting, your eyes rolling back into your head. Anyone watching the scene would have thought you were having a seizure.
But Sukuna knew. And you knew.
It was simply nirvana.
