It was around the time when the world begins to dim.
Two high school students sat on a park bench, deep in conversation. To any passerby, they looked like an ordinary, affectionate couple.
"You know... there's this kid in my neighborhood I'm close with," the girl began.
Her name was Raika Kurusu. Even accounting for the bulk of her blazer and down jacket, her curvaceous figure was undeniably captivating. She had long, black hair that seemed to catch the starlight, and sharp yet large, striking eyes. Standing nearly 170cm tall, her long, beautiful legs were even more prominent as she sat.
The boy was Yuto Watanabe. He was about average height for a guy, but shorter than Raika. He gave off the impression of being "cute" rather than "cool." Yuto nodded, prompting her to continue.
"We usually just see each other at this park and play a bit, but the other day... he confessed to me."
Yuto looked at his girlfriend in surprise. A confession. To a young boy, an older girl like Raika would naturally be an object of admiration. Moreover, she was beautiful enough to be hit on at school despite having a boyfriend. It was, in a sense, inevitable.
"At first, I thought about turning him down, but... Yuto. You like it, don't you?"
"Like... what?"
Raika brushed off his question with a smile—a smile as beautiful as a masterpiece.
"You know exactly what I mean... 'NTR' ❤️"
Yuto was blindsided. His mind immediately flooded with images of his beloved Raika and this neighborhood boy in an intimate embrace. His reason screamed that this was wrong, that a line was being crossed, but his instincts whispered something entirely different. The thought spread through his body like a potent toxin.
"...Are you serious?"
"Oh? Since you didn't lead with a 'no,' I take it you're interested."
"Just answer me. Are you being serious?"
"I am. Totally serious. And what about you? This is a once-in-a-lifetime chance."
Raika watched with amusement as Yuto frowned, lost in thought.
The premise of their conversation was something Yuto had already admitted to: he had a fetish for NTR. Or rather, Raika had more or less forced him to confess his deepest desires just the week before. Yuto knew his tastes were twisted, but he hadn't expected Raika's devotion to him to go this far.
"This is incredibly risky," Yuto muttered.
"I know. But isn't that risk just the spice you crave?"
"I... I don't want to drag you into my fetishes, Raika."
"Yuto. I love you. I'm willing to do anything you want."
Looking at her serious expression, Yuto found himself thinking—out of place as it was—how beautiful she was. His precious girlfriend, being "taken" by another. Specifically, a child. A dark thrill rose within him. He realized then that this was his answer.
"...Alright."
"Good ❤️ I have a great plan in mind. You won't be disappointed ❤️"
"Sigh... Fine. But the moment it looks like we'll get caught, or if things get dangerous, we stop. I might even step in to stop it myself."
"It'll be fine. Just leave it to your girlfriend ❤️"
Despite a lingering sense of unease, Yuto felt a surge of anticipation. NTR—or in this case, "cuckolding"—was something he had only ever seen in fiction. Now, he was going to experience it with his own beautiful, charming, and desirable Raika.
"...Oh my ❤️ Are you getting hard just imagining it? ❤️" "Wait—!"
Before he knew it, Raika's fingers were tracing the "tent" in his pants. Yuto's hips twitched at the sweet stimulation.
"I'm so happy ❤️ What were you imagining? Having my breasts fondled? My butt touched? Or... me being taken? ❤️"
"R-Raika... stop, please... ❤️"
Raika's fingers moved with supple grace. Just a bit of friction at the tip was enough to bring Yuto to the brink.
"Hehe ❤️ You look like you're enjoying yourself, though ❤️"
"No... I can't... please... ❤️"
"Alright ❤️ I'll stop for now ❤️"
Raika gazed at the panting Yuto with affection. Then, as if remembering something, she leaned her lips close to his ear.
"Oh—I should mention. No masturbating ❤️"
"...What?"
Yuto gasped, his secret plan to take care of things once he got home instantly seen through.
"No sex, obviously, but that's off the table too."
"B-but why?"
"Because we want this 'NTR' to feel as good as possible, don't we? ❤️ I'll hold back too. Let's endure it together ❤️"
Her sadistic smile was, of course, a sign of her affection for him. Perhaps, much like Yuto's fetish, Raika had discovered her own taste for "dominating" him.
"...Understood. No masturbating, no sex, until you say so."
"Good. I won't either."
The two stared at each other for a moment as a cold gust of wind blew between them.
"I'll have things arranged by next week."
"A week... that's a long time."
"Hehe. It'll be over in a flash. Just wait patiently."
Under the cold night sky, they left the park hand-in-hand. Since they were childhood friends living nearby, they felt a pang of reluctance to part. They walked home, the warmth of each other's hands the only heat they felt, wishing it would never end.
After school, Yuto Watanabe remained in the classroom alone. Most of his friends were at club activities or had already gone home, but he stayed behind to tackle his winter break homework.
With the end of the year approaching, the teachers had been uncharacteristically enthusiastic about assigning work. While Yuto felt a flash of irritation at the sheer volume, he worked with unprecedented intensity. He hoped that by focusing, he could push the excitement from his mind.
The talk of NTR at the park had left him in a state of constant arousal. If he let his mind wander for even a second, the mere thought was enough to make him want to touch himself. He poured all that pent-up energy into his studies, trying to find some release.
"It should be time soon..."
He muttered to himself, his face visibly worn with exhaustion. Then, with divine timing, his phone vibrated. He scrambled to check it. It was a message from Raika—the first in a week.
[Can you come to the park now?]
His heart hammered against his ribs, the pulse vibrating through his entire body. Crumpling his worksheets as he hurriedly packed his bag, Yuto sprinted out of the classroom. He typed a reply as he ran.
[on my way]
He didn't even have the presence of mind to fix his typos. He dashed toward the park at full speed, his lungs burning from the dry winter air, but he was too focused to care.
[im here. where are u]
Ping.
[The meeting hut. Enter through the back.]
Following Raika's instructions, Yuto turned toward the "meeting hut" on the west side of the park. It was little more than a small prefab shack. It had been built as a foundation for a proper community center, but the plan fell through, leaving only the shack behind.
Inside, it was about six tatami mats wide, containing only a bed, a desk, and a chair. It was occasionally used for first aid if someone got hurt. The "back entrance" wasn't the main door-window in front, but a door hidden behind a set of shelves on the opposite side.
Yuto entered quietly. Sensing someone inside, he hid between the shelves, completely concealed by a blue tarp. He peeked through a gap.
"—Hey... isn't it time yet? You're the one who invited me, Raika-san."
Yuto looked toward the source of the high-pitched voice—a boy who hadn't hit puberty yet. He had short-cropped black hair and a cute, childish face. He was short, barely reaching Raika's waist, and wore a black tracksuit. He likely just came from a sports club.
"Hehe. Just wait a little longer. I need to get ready—oh ❤️"
Raika, sitting on a chair next to the bed, soothed the boy as he swung his legs impatiently. Her eyes drifted from her phone to meet Yuto's. With a smirk, she looked back down at her screen.
Yuto realized she was about to message him and quickly silenced his notifications.
[Looks like you're here.]
[Yeah. I'm ready.]
[Ready for your girlfriend to be taken? ❤️]
[P-please...]
[It's fine ❤️ You worked hard this past week. Consider your ban lifted ❤️]
Raika wore that same sadistic smile. Yuto knew it was the signal—the act was about to begin. Between the run and the anticipation, his breath was ragged. He felt the blood rushing to his groin. Everything he had desired was about to happen right before his eyes.
"Sorry to keep you waiting, Leo."
"Ah! You done with your business?"
"Yes. Sorry about that."
"It's okay! Because...!"
Leo, the young boy, was visibly nervous, his eyes fixated on Raika's voluptuous body. Even at his age, the way he breathed heavily as he stared at her was undeniably primal.
"—Because you get to do whatever you want with me ❤️"
"Ah! Y-yeah!"
"You should be happy, Leo ❤️ You get to enjoy a body that men would kill to touch while you're still so young ❤️ You're incredibly lucky ❤️"
"I know! I know!" "...Enough talk, then ❤️"
Raika began by pulling off her blazer. Her chest, strained against the fabric of her white shirt, seemed to surge forward. Perhaps she was nervous too; her shirt was slightly damp with sweat, making her purple bra visible beneath.
She undid the buttons one by one, and her breasts—trapped until now—finally spilled out with a heavy bounce. Even in front of a boy who wasn't her boyfriend, she didn't hesitate. Only her bra remained. Since it was a front-clasp type, the final barrier was easily discarded by her own hands.
"The grand unveiling... ❤️"
The sight was breathtaking—pale, firm, and youthful skin that could only be appreciated at this age. Her large, pink areolas were perfectly proportional to her size, with prominent nipples standing at attention.
"So this is Raika-san's... ❤️ They're huge... ❤️"
"Hehe. Want to touch? ❤️"
"Yeah! ❤️"
Leo knelt on the bed behind Raika as she sat back. He reached around with his small hands and began kneading her breasts like dough—squeezing, mashing, and prodding them without any real technique. The sensation seemed fresh to Raika, as a sweet moan escaped her lips.
"Wow... ❤️ They're so soft... ❤️"
"Ah... hnn... ❤️"
"I've never felt anything like this... ❤️"
"Is that so... ❤️ ...Haa... ❤️"
"They're heavy, but I don't get tired of it. I want to touch them forever... ❤️"
"...Nn... Ah ❤️ Leo ❤️ I can't believe... ❤️ this is your... first time... ❤️"
Every time Leo's fingers brushed her nipples, Raika flinched. Noticing this, the boy quickly learned, increasing the stimulation to the tips.
"What cup size are you, Raika-san?"
"Nn... ❤️ I think... they're an L-cup."
"What?! A, B, C... that's way too big... ❤️"
"Ah, hah... ❤️ Don't squeeze so hard all of a sudden... ❤️"
Leo hugged Raika from behind, crushing her breasts with his arms. The sudden, intense pressure elicited a louder cry than before.
"I can't let you have all the fun. It's my turn to play... ❤️"
Raika turned around to face Leo. Stared down by her sculpted, beautiful face, Leo's face turned bright red. As if waiting for that moment, Raika pressed her plump lips against his. Then, true to her word, she began a thorough exploration of his mouth.
The sounds of their wet, intense kissing—squelching and slurping—were enough to make anyone lose their mind. Yuto was stunned.
He had never been kissed like that by her. Watching her give such a deep, passionate kiss to someone else—to Leo—sparked a flash of jealousy. But even that was instantly converted into fuel for his excitement.
"Mwah... ❤️ Slurp... ❤️ —Pah! ❤️"
"Haa... huff... huff... ❤️"
"Phew... ❤️ How was that?"
"The... best... ❤️❤️"
Seeing Leo's dazed expression, Raika tucked a strand of hair behind her ear, looking satisfied.
"I see, I see ❤️ Now... shall we try touching this? ❤️"
"Ah! Raika-san! ❤️❤️ It feels so good! ❤️❤️"
"Hehe. Your pants are already soaked with pre-cum ❤️ You're such a naughty boy, Leo ❤️"
Raika reached for Leo's pants and pulled them down. And then—
"Wait... what...? ❤️"
To the shock of both Raika and Yuto, Leo was not "small" by any means. His member, fully erect from Raika's kiss, was larger than Yuto's—larger, in fact, than most adults. It was a massive presence that seemed completely out of place on his small frame.
"You were hiding a weapon like this, Leo...? ❤️"
"Huff... huff... ❤️ Raika... san... ❤️"
"I suppose asking what you want would be pointless ❤️"
"Yeah! ❤️ I can't... hold back anymore! ❤️"
"Fine, fine ❤️ Here—"
Raika let her voluptuous body fall back onto the bed. She was naked from the waist up, with only her skirt and black tights remaining below. As if mocking that thin defense, she spread her legs into an 'M' shape, flaunting her most private area to the boy.
"—Want to try... using my pussy... ? ❤️"
Raika's panties were already soaked through; the purple fabric had darkened with her own arousal. Seeing his girlfriend so turned on made Yuto's heart ache, yet he couldn't look away. Before he knew it, Leo had rolled a condom onto his oversized member—apparently, Raika had brought them along.
"Hah... hah... ❤️ Pussy... Raika-san's pussy... ❤️"
"I guess it's a good thing I bought the large size by mistake... ❤️"
"Can I?! Is it okay now?! ❤️"
Leo approached her with the eyes of a predator. Raika sighed in resignation.
"Yes, you ca—AAAAH?! ❤️❤️"
Before she could even finish her sentence, Leo lunged. With a wet squelch, he buried himself deep inside her. The impact forced a sound out of Raika that Yuto had never heard before.
"Ugh... ooh... ❤️ It feels so good... ❤️❤️"
"Wait... ❤️ I told you... not to go in... so hard... ❤️ ...Nn! ❤️ Not... like... th-thaaaat! ❤️"
"It's so tight! Raika-san, your pussy is so tight! ❤️"
"Shut up... ❤️ You were a virgin until a second ago... ❤️"
"Oh! That's right! I'm not a virgin anymore! ❤️"
Emboldened by that realization, Leo began to thrust. What started as clumsy, hesitant movements quickly evolved into something much more intense.
"Ngh... uuuh... ❤️ Nn... ❤️ Nn... ❤️"
"Raika-san! Raika-san! Raika-san! ❤️❤️"
The rhythm accelerated. Leo leaned down to suckle on Raika's large breasts, the wet sounds of his nursing filling the room.
"Nn... ❤️ Oh... ❤️ Oh... ❤️ Leo... ❤️ You're... so good at this... ❤️ Ah... ❤️"
"Hah... hah... ❤️ Breasts... they're delicious... ❤️"
"Are you... even... listening... AAAAAH! ❤️❤️"
As the wet slapping sounds grew louder, Leo seemed to find his stride, while Raika was overwhelmed by wave after wave of pleasure.
"Ngh! ❤️ I'm coming! I'm coming! I'm... ooh! ❤️ Ooooh! ❤️ Ahh... ❤️ Leo... Leo... ❤️"
Hearing her call his name in the throes of climax, Leo realized for the first time just how much he was dominating her.
"Yes! Raika-san! ❤️"
"Ooh... ❤️ ...Your... cock... ❤️ It's going to... make me go again... ❤️ No... wait... ❤️"
"What is it? ❤️"
"It feels... ❤️ ...Too good... ❤️ I can't... oh! ❤️ Oh! ❤️ No... ah! ❤️ I'm going... I'm going again! ❤️❤️"
Watching from the shadows, Yuto was mesmerized. He had never heard her moan like this. Seeing her brought to such a state by another male—that was the ultimate thrill of NTR.
Leo stopped for a moment, pulling out with a wet sound. He looked at Raika's dazed face and spoke.
"I want to do it from behind now. ❤️"
"Huff... huff... ❤️ From... behind...?"
"Yeah! I want to see your butt while I do it! ❤️"
"...Doggy style, then. Hold on."
Raika rolled onto her stomach, revealing a rear that was just as impressive as her chest. Yuto felt a pang of regret that he had never noticed just how erotic her silhouette was from this angle.
".... ❤️"
"...The silence is a bit embarrassing, you know."
"It's so hot!!! ❤️"
"I-is it...? Well, good for you ❤️ And now...?"
She wiggled her hips, teasingly bumping them against his member.
"—You're not done yet, are you? ❤️ Le~o ❤️"
Thud... Squish...
"AAAAAH! ❤️❤️ ...Ah... I'm coming... oh... ❤️❤️"
Just the act of him re-entering her from behind was enough to send Raika over the edge again.
"It feels even tighter from here! This is amazing! ❤️" "Oh! ❤️ Hah... ❤️ Oh... ❤️ Oh... ❤️ Oh... ❤️"
Raika was now making purely primal sounds. Satisfied, Leo began to hammer away. The sound of their bodies colliding was deafening, and Raika was lost in a continuous peak of pleasure.
"Ooh! ❤️ Oh! ❤️ Oh! ❤️ Oh... ❤️"
Leo thrust with animalistic instinct. Every time Raika moaned, it only drove him to push harder.
"... ❤️ ... ❤️ ... ❤️"
Eventually, Raika's voice began to trail off, but Leo didn't stop.
"Nn... ❤️ ...I'm coming... ❤️ Nn... ❤️ Haaah! ❤️❤️"
Seeing her climax again only fueled Leo's fire. He wrapped his arms around her waist, pulling her closer to drive himself as deep as possible. They both knew the end was near.
"Wait, Leo, stop... AAAAAH! ❤️❤️❤️"
Slap! Squish! Thud!
Leo could no longer contain himself. He slammed his hips against her with more force than ever, ignoring Raika's desperate protests as he bottomed out against her cervix over and over.
The pressure in his loins reached the breaking point. Leo focused entirely on the sensation of release.
"...Aaah... ❤️ ... ❤️ ...Oh... ❤️ ...Oh... ❤️" "I'm coming! It's coming, Raika-san! I'm letting it all out! ❤️❤️" "Oh... ❤️"
Leo pressed himself deep against her cervix. Even through the condom, the intent was clear: he was going to leave his mark on the most precious part of her.
"Hmph... HAAAH! ❤️❤️ ...AAAAAAAGH! ❤️❤️❤️"
An explosion of pleasure surged from Leo, and the sensation seemed to spark a sympathetic reaction in Raika.
Squirt... Gush... Splatter...
"Nn... OOOOH! ❤️❤️ ...I'M GOING... ❤️❤️ Ooooh... ❤️ ...Nn! ❤️ Ah... ❤️ AAAAAH! ❤️❤️ ...Ooh... ❤️"
Raika's body arched, her spine stiffening. She tried to scramble away, but Leo's grip on her waist held her firm as he emptied himself deep inside the condom.
In the shadows, Yuto felt a warm, sticky sensation in his own pants. He had reached his limit at the exact same moment. It was the most intense release he had ever experienced.
"Huff... ❤️❤️ Huff... ❤️❤️ ...Heh... heh... heh... ❤️"
The moment Leo released her waist and pulled out with a wet pop, Raika collapsed. She looked like a broken doll, her reason completely obliterated by the sheer intensity of the pleasure. Her body continued to twitch in small spasms.
"Nn... hah... ❤️ ...Oh... ❤️ ...Aaah... ❤️"
"Raika-san ❤️ That was... the best ❤️ I'm all empty... ❤️"
"... ❤️ ... ❤️ ... ❤️"
Leo stood up slowly, leaving the still-shaking Raika on all fours. His member swayed heavily, the condom filled with a significant amount of white fluid.
"...Haa... ❤️ Nn... ❤️ ...Leo, come here... ❤️"
Raika rolled onto her back and beckoned Leo. Then, she began to take him into her mouth. It was a "cleanup" fellatio—something even Yuto had never experienced. The fact that she was so devotedly cleaning up after such an intense session with another boy only fueled Yuto's sense of inferiority—and his excitement.
"Mmm... ❤️ Gulp... ❤️ Slurp... ❤️"
Raika licked every inch of him, from the base to the tip, cleaning away every trace of the encounter. She seemed to savor it, while Leo looked down at her with a smug, triumphant grin.
"Mwah... ❤️ ...Haa... ❤️❤️"
After finishing, Raika opened her mouth to show him she had swallowed everything. Leo's eyes widened in delight, and he pulled her into a tight hug.
"Raika-san! ❤️"
"What is it, Leo? ❤️"
"I love you... ❤️ I really, really love you... ❤️"
"Ahaha ❤️ I see. I like you too, Leo ❤️"
Even though her words sounded like she was just humoring a child, Yuto felt the weight of being "replaced." Something inside him snapped.
Leo checked his phone and hurriedly began to dress. It seemed his time was up.
"Ah, crap! I gotta get home!"
"I see. It's that time already. Be careful on your way back."
"Yeah! ...Oh, one last thing!"
Leo leaned in and gave Raika a quick kiss on the lips.
"...I'm serious about loving you."
With that, Leo ran out. Yuto held his breath, waiting for the footsteps to fade into the distance before taking a deep breath.
"Haa... —!"
His pocket vibrated. He looked at his phone.
[Did you enjoy the show?]
He looked up toward the center of the room.
"Hehe ❤️"
There stood Raika, completely naked. Her black hair was a mess, and her skin was glistening with sweat. Her breathing was still ragged, her cheeks flushed, and her eyes moist.
To anyone, she looked exactly like what she was: a woman who had just been thoroughly enjoyed. And the one who had done it wasn't Yuto, her boyfriend, but a boy named Leo. Yuto was speechless.
"—Look, Yuto ❤️"
"W-what...?"
"Leo's cock went all the way in to here ❤️"
She placed her finger a few centimeters above her navel, silently praising the boy's size. Realizing that the boy had reached depths that he himself couldn't, Yuto felt a flare of jealousy.
"Ah... ugh..."
"You've never seen me lose control like that, have you? ❤️"
"Guh... ❤️"
"I know, I know ❤️ After all... Leo's was much bigger than yours, wasn't it? ❤️"
Faced with her uncharacteristic sadism, Yuto felt a mix of crushing humiliation and soaring arousal.
"Hehe. Did you hate it? Or were you satisfied too?"
"..."
"I'm doing this because I want to see you this excited, Yuto."
"...I was... excited... ❤️"
"Good ❤️ That's my boyfriend for you ❤️"
"...Raika, about that—"
Yuto hesitated. Raika tilted her head curiously. The words that followed would change their relationship forever.
"—Can we... do it again?"
Raika gave him a wicked grin.
"Of course. We'll be doing this plenty more ❤️ My little pervert boyfriend ❤️"
Yuto felt his member twitch again. Whether the emotion swelling in his heart was joy at the thought of repeating this thrill or a growing sense of regret, even he didn't know.
The winter air outside the prefab shack was biting, a stark, clinical contrast to the sweltering, musky atmosphere they had just left behind. Inside that cramped six-tatami space, the scent of sex—heavy, salt-tinged, and unmistakable—still hung in the air like a physical weight.
Yuto finally stepped out from behind the blue tarp, his legs feeling heavy and uncoordinated, as if the ground beneath him had shifted its axis.
He looked at Raika. She hadn't moved to dress herself yet; she stood there in the dim, flickering light of the single overhead bulb, her skin pale and shimmering with a fine sheen of sweat.
Her chest still heaved with the aftershocks of a climax he hadn't provided. She looked like a woman who had been thoroughly conquered, a masterpiece of disheveled elegance, and the sight sent a fresh, agonizing jolt of electricity through Yuto's spine.
"Come here, Yuto," she beckoned. Her voice was low, honeyed with a husky edge that vibrated in the small room.
He obeyed, moving toward her like a moth drawn to a flame that had already scorched him. When he reached her, she didn't offer a comforting hug or the chaste kiss of a girlfriend. Instead, she reached out, took his trembling hand, and pressed it firmly against her lower abdomen—right where she had indicated the boy's staggering length had reached.
"Can you feel it?" she whispered, her eyes locking onto his with a terrifying intensity. "The heat he left inside me? It's still pulsing. He was so... aggressive, Yuto. So raw. It's a different world from the way you touch me."
Yuto flinched, the words stinging like a physical lash. Yet, he didn't pull away. This was the poison his psyche had demanded, the bitter medicine of his own twisted desires.
"I... I saw. Everything," Yuto managed to choke out, his voice cracking.
"I know you did. I could feel your eyes on me the whole time," she said, a small, triumphant smile tugging at the corners of her lips.
"It made me even wetter, knowing my boyfriend was watching me be taken by a boy who's barely hit his growth spurt. He's going to be a monster when he grows up, Yuto. He didn't even care that I was older. He just wanted to claim me. To breed me."
The Walk into the Cold
They eventually dressed in a heavy, loaded silence. Raika smoothed her skirt and adjusted her blazer with a practiced grace, though the faint scent of Leo still clung to her skin. They slipped out of the 'meeting hut,' the rusted door creaking a lonely farewell, and stepped back into the quiet, frozen streets of their neighborhood.
The walk home was surreal. The world looked the same—the same cracked pavement, the same glowing vending machines, the same suburban houses—but everything felt fundamentally altered. Yuto walked a half-step behind her, his eyes constantly drifting to the sway of her hips. He kept visualizing the boy's hands there, kneading that soft flesh.
The physical distance between them felt like a vast canyon, yet they were bound tighter than ever by the secret they now shared. The streetlights cast long, distorted shadows ahead of them, stretching their figures until they looked like giants in the dark.
"Are you okay?" Raika asked softly, breaking the silence. The sadistic edge in her voice had softened into a grounded, almost maternal curiosity.
"I don't know," Yuto admitted, his breath hitching in the freezing air.
"I feel... empty. But also like I'm waiting for something. Like the world has lost its color, and the only thing that's bright is... what happened back there."
Raika stopped walking, standing beneath a flickering streetlight that hummed with a low-frequency buzz. She reached up and cupped Yuto's cheek, her thumb tracing the line of his lower lip. Her touch was cold from the wind, but her eyes were burning.
"That's the 'crossover,' Yuto," she said, her voice a soothing velvet. "You've stepped over the threshold. There's no going back to a 'normal' relationship now. Every time I kiss you from now on, you'll wonder if I've kissed Leo that day. Every time we're together, you'll be thinking about how much bigger he was, how much deeper he went."
"And you?" Yuto looked at her, searching for a trace of guilt that wasn't there. "Do you... do you actually like him? Are you going to leave me for a kid?"
Raika laughed, a melodic sound that felt like a serrated blade across his heart.
"I love you, Yuto. Never forget that. But Leo... Leo provides a specific kind of thrill. He's raw, untainted by the 'rules' of being a boyfriend. When he's inside me, he's just a male claiming a female. And seeing that destroy you and excite you at the same time? That's my new favorite drug."
The Lingering Heat
They reached the fork in the road where their paths to their respective houses diverged. Usually, this was where they would share a sweet, lingering goodbye. Tonight, the air was heavy with the unspoken.
"I'll message you," Raika said, her eyes glinting with a mischievous light. She leaned in, her lips brushing against his ear. "Don't try to wash the image away tonight, Yuto. Let it simmer. I want you to be starving for more."
She turned and walked away, her silhouette disappearing into the darkness of the neighborhood. Yuto stood there for a long time, his hands shoved deep into his pockets, clutching his phone as if it were a lifeline.
When he finally got home, he skipped dinner and went straight to his room. He lay on his bed, staring at the ceiling in the dark. The 'ban' on sex and masturbation had been lifted, but he found he couldn't bring himself to touch himself. The image of Raika—his Raika—arching her back under the weight of that boy was too dominant, too overwhelming.
He fell into a fitful sleep, only to be jolted awake by the buzz of his phone on the nightstand. It was 2:00 AM.
He expected a message from Raika. Instead, it was an unknown number. He swiped the screen, his heart hammering against his ribs.
Unknown: Raika-san told me I could message you. She said you liked watching. I'm meeting her at her house tomorrow after practice. Her parents are out. You should come over.
Yuto's blood ran cold, then surged with a heat so intense it made his head spin. The boy—Leo—wasn't just taking his girlfriend; he was inviting the 'witness' back to the sanctuary of Raika's own bedroom.
The game hadn't just begun. It was evolving into something far more dangerous.
