How to Teach your Dog a New Trick

Summary:

Goro Akechi, the student council president of Shujin Academy has his head filled with far too many responsibilities. But more than any of his duties, his thoughts were consumed by one person—his adorable underclassman, Ren Amamiya.

The shy, timid boy was like a sweet, obedient puppy to Goro, and the idea of having Ren all to himself, of breaking that innocent demeanor, thrilled him. Goro longed to ruin the sweet boy in ways only he could imagine.

What Goro didn’t realize, however, was that behind Ren’s quiet exterior lay a darker desire. Ren had his own plans—to ruin Goro, and to do it in the roughest way possible.

Goro really wants to get fucked by his kouhai, except his kouhai fucks him faster before Goro can act.

Chapter Text

The droplets hitting the window caused no impact on the student council president. He’s tenderly listening to the sound outside, papers were scattered in front of him in haphazard piles — expense reports, club funding requests, handwritten meeting notes scribbled hastily in blue ink. 

 

Goro’s pen moved in a fluid dance across the page. He yawned, propping his right hand against his cheek, while his eyes scanned the weather situation outside. 

 

To be honest, even the water crashing against the glass window was more interesting than the endless stacks of paperwork piled in front of him. Goro despised the position the school had forced upon him. He hated being the president. The constant need to maintain perfect grades, his image, and deal with the tiresome school administration was beyond exhausting, a weight that never seemed to lift. 

 

At least the role came with one perk — the freedom to skip classes without much need for explanation. The school seemed to look the other way as long as he was “occupied with official duties.” Goro could shut himself away in the student council room under the guise of “school work,” where he’d often steal a few precious minutes to catch up on his already messed up sleep schedule. 

 

Goro’s pen paused over the paper, his eyes drifting back to the window. The rain slid down the glass in thin, trembling lines. He wished, for a fleeting moment, that he could just disappear into that rain — let it wash him away, cleanse him of the suffocating weight of responsibility that had been pressed onto his shoulders ever since he had started this facade.

 

His fingers tightened around the pen, his knuckles pale against the dark wood of the desk. The role was a crown he had chosen to wear, but it felt more like a cage made of glass — fragile and transparent, threatening to shatter with the slightest misstep. To everyone else, he was the perfect picture of poise and diligence: a flawless leader, unshakeable in his resolve. He’d cultivated that image so carefully, like an artist working on a sculpture from stone, smoothing away every imperfection, every rough edge. But no one saw the cracks beneath the surface.

 

Goro felt the familiar twist of irritation curl in his chest, like a snake coiling tight around his lungs. This constant pressure to perform, to be more than just himself — it was a role he’d slipped into with a smile, but now it felt like chains he couldn’t take off. Every form, every signature was another stitch in a garment he didn’t want to wear. He was supposed to be perfect; his handwriting couldn’t falter, his decisions couldn’t waver, his smile couldn’t slip. He was the president, after all. He had chosen this, hadn’t he? 

 

Goro stretched his back, frustration making it impossible to concentrate on the paperwork before him. With an impatient sigh, he swept the remaining documents into his desk drawer, locking them away from prying eyes. Taking a deep breath, he allowed a soft smile to form on his lips before stepping outside the room. 

 

“Good morning, Akechi-kun!” a petite girl immediately called out, her cheeks flushed a delicate pink. She clutched her textbooks tightly to her chest, her eyes fixed on the floor, too nervous to meet Goro’s gaze. Goro returned her greeting with a polite smile. “Good morning. I’m afraid I don’t have time for idle chat,” he said with a nod.

 

The girl’s face briefly fell, but she quickly recovered with another smile. “O-Of course! I’m sorry, you must be busy,” she stammered. Goro offered a brief smile before moving past her.

 

The hallway was bustling with students, many of their eyes drawn to him. The girls whispered among themselves, their cheeks flushed with red, while some of the boys clenched their jaws in envy and others looked at him with admiration. The group of voices—whispers, gossip, and greetings—was nearly unbearable. Goro was so  irritated today. 

 

“Isn’t that the president?”

 

“Gods, he’s so hot. I want his number.”

 

“I heard he killed his own girlfriend!”

 

“I’m too nervous to speak to him.”

 

Goro’s hands clenched into fists at his sides, nails biting into his palms. His face felt hot, his breath coming quicker, and he kept his eyes fixed straight ahead, trying to will himself calm. Every glance felt like a weight pressing down on his shoulders, every word like a needle poking through his skin. The walls seemed to close in, the corridor narrowing with each step he took. Goro’s heartbeat was a wild, erratic rhythm now, his chest tightening with every whisper he pretended not to hear.

 

They see what they want to see, Goro told himself, trying to swallow the lump that had formed in his throat. A perfect president, a model student. 

 

Just a few more steps. Goro could feel the weight of their expectations pressing down on him, a thousand invisible hands pushing him deeper into the ground.

 

He reached the end of the hall, where the noise was quieter, the crowd thinner. His breath came in ragged gasps, his chest burning, but he kept moving. Goro couldn’t stop, couldn’t let them see. He was the president. He had to keep it together. Had to be perfect.

 

I’m fine, you’ve done this countless times before, Goro lied to himself, over and over like a mantra, as he finally pushed through the door and stepped into the cool, empty air outside. 

 

I’m fine. I have to be.



This doesn’t usually happen. Goro had grown accustomed to the attention, but even he had his limits. And right now–the voices– Goro is going to scream, he’s going to scream and everyone will whisper louder–

 

“Akechi-senpai?” The voice broke through his thoughts like a ripple across still water. Goro turned sharply and spotted his savior: a shy, timid boy with messy black hair and glasses that seemed slightly too big for his face. He stood a little shorter than Goro — not by much, but enough to be noticeable. Amamiya Ren .

 

Goro calmed himself down, taking a couple of deep breaths. He can’t mess this up. He’s just tired. 

 

His smile came naturally, without the usual effort of stretching his lips into the perfect mask. It felt… real, even to him. Ren’s fingers fidgeted nervously as he glanced to the side. 

 

“I… I came to return the book you borrowed me,” Ren stammered, his voice soft but steady. “I think the topic is really interesting. Maybe we could discuss it after school?”  

 

Goro’s smirk deepened at the attempt — was Ren asking him out? If it had been anyone else, he would have made up an excuse in an instant. But Ren wasn’t just anyone .

 

“That sounds delightful,” Goro replied smoothly, his smile widening. “I’ll make time for you in my schedule.”  

 

Ren’s cheeks flamed a brighter red, but he smiled back, his nervousness somehow endearing. “Great! Then… I’ll see you after school!” he managed, before hurrying off toward his class, casting one last glance back over his shoulder.

 

Goro watched him go, a familiar warmth spreading through his chest. 

 

After seeing him, Goro’s breathing had steadied. He felt calm. His heart was still racing, but not from panic. With renewed focus, he moved swiftly to his class, the earlier encounter with his beloved making him invincible to the whispers, gossip, and curious stares that usually clung to him like static in the air.

 

The lecture began, but Goro found it impossible to concentrate. How could he? He’d seen Amamiya today — Ren Amamiya. The thought of it alone sent a flutter of excitement through his chest. A smile tugged at his lips, refusing to fade. His underclassman was so precious, so irresistibly charming. The way Ren glanced at him, the shy comments, every little thing he did seemed flawless in Goro’s eyes.

 

His gaze drifted to the window, watching the rain trail down the glass in thin, winding rivers. He remembered another rainy day, not so long ago. Back then, it had rained too.

 


 

It was during Goro’s second year, when he’d been elected student council president for the second time. The title was meant to bring prestige, but it had brought him troubles instead. He’d been met with suspicion and distrust, the whispers and hateful glances of those who doubted him. 

 

So, Goro did what he always did best: he pretended. He pretended it didn’t bother him, that he couldn’t hear their hushed voices. He wore the mask of a perfect, untouchable student, and they devoured the performance like starving children.

 

But not Ren. Ren saw through the facade. Ren didn’t see the student council president, Akechi — he saw Goro .

 

It had been raining heavily that day, the downpour relentless, and Goro had realized with irritation that he’d forgotten his umbrella. The students around him, though close, kept their distance — too afraid to speak to him, too shy to approach. They hovered like a swarm of tiny, buzzing insects, always circling but never daring to come near.

 

“Um, excuse me… you don’t have an umbrella, right?” A voice spoke up beside him, hesitant but clear. Goro turned, expecting another admirer or someone ready to sneer, and instead found himself looking at an average student with messy black hair and a pair of dark glasses.

 

Goro forced his well-practiced smile, hiding the annoyance gnawing at him. “It’s fine. I don’t mind a little water,” he lied smoothly.

 

The boy studied him for a moment — he must have been a first-year, still young enough to be earnest, still brave enough to ask questions. Then, he turned his gaze slightly away, his voice soft but steady. “Are you… upset? I mean, it must be tough, with everyone talking about you. But… I don’t care about silly rumors. Here, take my umbrella.” He extended a simple black umbrella toward Goro, his hand trembling just slightly.

 

Goro blinked, taken aback. The boy's kindness was unexpected, disarming. He saw past his facade, straight through the mask. The rain fell harder, but for a moment, Goro didn’t mind the downpour at all.

 

Goro stared back for a few seconds, the boy’s words sinking in like stones in still water. His chest tightened, and his eyes widened. How did he…?

 

Before he could finish the thought, the boy interrupted, pushing the umbrella into Goro’s hand with a gentle insistence. “It’s okay to not be the president for once. I’m talking to Akechi-senpai, not President Akechi-senpai.”

 

And then, just like that, the boy turned and walked away, quickening his pace as the rain soaked his hair, droplets sliding down his glasses.

 

Goro watched him retreat, his eyes lingering on the figure until it disappeared into the curtain of rain. Slowly, he glanced down at the umbrella in his hand, feeling the cool metal of the handle against his skin. It’s okay to not be the president for once. I’m talking to Akechi-senpai, not President Akechi-senpai.

 

It was the first time… The first time anyone had noticed the cracks in his facade, the first time someone had seen past the mask he wore and spoken to the person beneath. The first time anyone had truly listened.

 

Goro’s grip tightened around the umbrella, his knuckles paling. 

 

Maybe, deep down, he’d been waiting for this — for someone to see him, too.

 


 

That had happened last year. After that unexpected encounter, Goro and Ren grew closer, a deep friendship blossoming between them. It didn’t take long for Goro to realize that Ren felt something more — an attraction that went beyond simple admiration. 

 

He had stumbled upon it by accident, passing by the restroom during class hours, when he overheard Ren's breathy, desperate gasps–he was stroking himself–and the unmistakable sound of his own name falling from Ren's lips, over and over again.

 

That same day, when Goro returned home, he’d found himself unable to resist. He had fingered himself with a desperation he hadn’t known he could feel, his fingers moving with such intensity that his body ached for days afterward.

 

Now, more than a year had passed since Goro acquired this gem. Goro’s little crush had grown into an almost obsessive fondness. Ren was simply irresistible — a perfect mix of shy and bold. At times, he was adorably hesitant, but when the moment called for it, he would transform into a teasing, playful troublemaker, effortlessly pulling reactions from Goro that he hadn’t known he was capable of.

 

Ren brought out something in him, something that felt wild and alive, something Goro hadn’t dared to acknowledge before.

 

If you asked Goro, he would compare Ren to a well-behaved dog—always wagging his tail around him, pathetically howling in delight whenever Goro agreed to spend time together. The sight filled Goro with a rush of excitement; it made him feel in control, and that was the thing he loved most of all.

 

He was a good boy, really. Loyal to Goro. He followed instructions well, always at his heels, always looking up with those wide, adoring eyes that seemed to ask, Am I doing this right? It was almost endearing how much Ren craved his attention—his praise. A little pat on the head, a word of encouragement, and he’d light up like the sun was shining just for him. So easy to control. So easy to leash. 

 

Ren was also clumsy, but there was something oddly adorable about it. Like a dog trying to carry a stick too big for its mouth. 

 

He liked that about him, though. Goro liked how the younger boy’s world seemed to revolve around him, how he would come running at the slightest call of his name. There was a certain satisfaction in knowing that with just one snap of his fingers, his loyal little dog would come bounding over, ready to serve, ready to please. His underclassman was like a well-trained pet, always there, always eager, always his.

 

But Goro couldn’t deny that there was a certain power in it, too—a certain pleasure in knowing that he could make those eager eyes cloud over with doubt or fear with just a single harsh word, that he could pull the leash tighter whenever he wanted. Make Ren choke and suffocate on his tears. Goro knew he was the center of his universe, and he liked it that way. Maybe he liked it a little too much.

 

Ren didn’t know it, of course. He didn’t know how much his every move, every breath, every wag of tail was being monitored, analyzed, judged. But that was okay. He didn’t need to know. As long as he stayed obedient, as long as he kept coming back, panting and hopeful, everything would be fine.

 


 

Class ended soon enough. Goro, with his aura of the perfect student, had a way of fading into the background for the teachers, giving him the freedom to drift in and out of his daydreams. The moment he stepped out of the classroom, he was confronted by the vice president, Makoto Niijima. She stood with her chin held high, her gaze locked directly onto his. Bold.

 

“Sorry to bother you, Akechi. I just wanted to discuss the funds for the upcoming trip,” she began. Goro nodded, making a show of listening while trying to not to ignore her.

 

But her voice quickly faded into a dull buzz as something caught his eye. Amamiya .

 

And he wasn’t alone. 

 

A tall, messy-haired blond was laughing and chatting with his pathetic dog. Ryuji Sakamoto—that was his name. One of the few students who didn’t bother to hide his distrust, always glaring and sneering at Goro from a distance.

 

And lately, Goro had noticed how much more often Amamiya and Ryuji were talking. Getting friendlier. Getting closer.

 

They’re just friends , he told himself. Calm down.

 

But he felt his chest tighten, the familiar stirrings of anger and jealousy creeping in again..

 

What was Ren doing? His loyal, eager pup was wagging his tail for someone else. No… Not like a pup. Like a dirty mutt.  

 

Goro’s eyes narrowed as he watched them—Ren’s head tilted slightly, his expression attentive, too interested. Ryuji laughed, and Ren laughed with him, the sound light and carefree. It grated on Goro’s nerves like nails on a chalkboard.

 

Goro felt a simmering anger bubble in his veins, mixing with something darker, something more primal. How dare he? How dare his dog look so pleased with anyone else? That wagging tail, that bright, eager gaze—it all belonged to him, didn’t it? Ren was his . Goro had trained him, molded him, made him feel that thrill of belonging. And now here he was, acting like a stray, showing that same stupid smile to someone else.

 

He hated it. The jealousy gnawed at him, clawed its way up his throat like parasyte. It wasn’t just irritation; it was a deep, burning possessiveness, a feeling that twisted his insides into knots. Ren should know better. Ren should understand where his loyalty lies, where he belonged. How quickly did dogs forget their masters when a new hand offered them a pat on the head? How easily did they wander when not kept on a short leash?

 

Goro clenched his jaw, fighting the urge to storm over there, to grab Ren by the collar, and remind him exactly where he stood—right by his side. He’d have to teach his pet a lesson, remind him that a good dog doesn’t stray. That excitement, that devotion—Goro wanted it all back, every bit of it, and he’d make sure he got it.

 

"Akechi-kun?" Makoto’s voice cut through his thoughts. Goro’s attention snapped back to her, and he quickly restored his polite smile. "Yes. I believe you’re more than capable of handling this, Niijima. Your plan sounds great; it has my approval," he replied, offering her a quick, dismissive smile before stepping past her. Makoto seemed momentarily taken aback by his abruptness but quickly moved on.

 

“Amamiya,” Goro called out, his voice smooth but firm. Ren’s head turned immediately, his eyes lighting up with that eager look that both pleased and disgusted Goro. Ryuji, beside him, shot Goro a wary glance, his smile vanishing in an instant.

 

“Ah, Akechi-senpai!” Ren greeted him cheerfully. How pathetic. His dog had licked someone else’s hand, and now he wanted to crawl back to Goro with a dirtied mouth.

 

"Hey, bro, I, uh… I got something to take care of. I’ll text you later," Ryuji quickly mumbled, casting one last heated glare at Goro before leaving. Ren nodded, turning his full attention to Goro with that same stupidly trusting look.

 

“Right. You said we would hang out, right? So—”

 

“I’m afraid something urgent has come up,” Goro interrupted smoothly, lying with ease. “Someone important to me has requested my time, so I must attend to them instead.”

 

He savored the immediate change in Ren’s expression—the way his smile faltered, his eyes flickering with confusion, and the corners of his mouth quivering, unsure of how to respond. Still, Ren forced a smile, his voice slightly strained. "I see, that’s fine! Don’t worry. I’ll just see you around," he replied, before quickly retreating.

 

Naughty dogs needed to be disciplined.

 


 

Goro’s footsteps echoed against the concrete sidewalk as he made his way home, each step heavier than the last, fueled by the simmering rage that clawed at his insides. His jaw was clenched so tightly it hurt, and he barely noticed the cold wind biting at his skin or the passing faces blurring around him. His mind was consumed by a single image: Ren, his so-called loyal dog, cheerfully whimpering for someone else.

 

He felt his anger flare up again, a white-hot flash behind his eyes. How could he? After everything, after all the time Goro had making him feel special, needed—how could Ren dare to let someone else into his little world? He could still see it so clearly: the way Ren had laughed, that soft, stupid smile plastered on his face, while that idiot Ryuji stood beside him, far too close.

 

Goro’s fists tightened at his sides, nails digging into his palms. Sakamoto. Of all people, it had to be him. That loud, obnoxious fool who barely knew how to keep his mouth shut and always looked at Goro with unmatched arrogance. And now, there he was, worming his way closer to Ren, to his Ren.

 

Goro hated it. Hated the idea that Ren’s attention—his precious, devoted attention—could so easily be divided, could be given to someone who hadn’t earned it, who didn’t deserve it. What kind of dog forgot its master so easily? What kind of pet ran off to sniff around someone else the moment they got a little attention?

 

His thoughts grew darker, more twisted. Maybe he hadn’t been strict enough. Maybe he’d been too lenient, too kind. Ren had gotten too comfortable, too sure of himself, too willing to wander. Goro felt a wave of fury crash through him. He had to remind Ren of his place, had to make him understand that there were consequences for disobedience.

 

Goro quickened his pace, his shoes hitting the ground with sharp, angry clicks. Ren needed to be reminded who held the leash. Goro wouldn’t let anyone else—least of all a fool like Sakamoto Ryuji—take what was his. He felt his lip curl into a sneer. If Ren thought he could just trot around, sniffing at others without repercussion, he was sorely mistaken.

 

He’ll learn. Goro thought, his eyes narrowing as he stared ahead, not really seeing the path in front of him. A punishment was in order. 

 

Because Ren was Goro’s until he would decide to put him down like sick dog.

 

______________



Another day passed, and Goro hadn’t seen Ren at all. According to what Niijima had told him, Ren had gotten himself into trouble this morning and was now in detention for assaulting a fellow classmate.

 

Apparently, no one knew exactly how the fight had started, so Ren had been sentenced to detention while the other student was handed a different punishment, helping other clubs after school. Conveniently, Goro had been given the task of supervising Ren this afternoon.

 

Pure coincidence, of course. It wasn’t as if Goro had paid a troublesome student to provoke Ren into throwing the first punch. And he certainly hadn’t burdened Niijima with an endless list of tasks to keep her occupied and out of the student council room. No, Goro hadn’t planned any of this. He has

 

It was around four in the afternoon when the door to the student council room creaked open.

 

“Good afternoon, Akechi-senpai…” Ren mumbled, nervously fidgeting with his fingers. A bandage was plastered across the bridge of his nose, his hair slightly disheveled, but otherwise, he looked unharmed.

 

“Nice to see you again, Amamiya. Although I wish it were under different circumstances,” Goro replied, his smile sweet but his eyes cold.

 

Ren chuckled awkwardly, scratching the back of his head before taking a seat. “Don’t mind me, I’ll just study,” he said quietly. Goro nodded, attempting to look interested in his paperwork, his eyes flickering with satisfaction as Ren turned his attention to his books. Once he was sure Ren was distracted, Goro silently moved to the door and locked it, ensuring they wouldn’t be interrupted.

 

Ren glanced up, confused, and Goro offered a calm smile. “You need to focus on studying, right?” 

 

“Yeah, but I’ve got this, so don’t w—”

 

“Let me help,” Goro interrupted smoothly, slipping closer to the desk. He took the seat right next to Ren, sitting just a little too close, their knees almost touching. Ren stiffened, his breathing hitching.

 

Good, Goro thought, watching him carefully. His precious pet looked nervous, uncertain, just the way he wanted him. He leaned in a bit closer, his voice a low murmur, “After all, it’s important that you learn your lesson.”

 

Ren’s fingers trembled slightly, and Goro’s smile widened. Naughty dog. He’d make sure Ren understood exactly who held the leash.

 

“Akechi-senpai, I wasn’t the one who started the—”

 

“Don’t worry, I know,” Goro cut him off. “You’re not the type to start fights.” His voice was calm, reassuring, and Ren seemed to relax, exhaling slowly as his eyes drifted back to the papers in front of him. But that wouldn’t do. Not at all.

 

“What’s this? Creative writing?” Goro asked, his tone light. Ren glanced up, a hint of nervousness in his eyes. “It’s for my literature class,” he replied quietly. 

 

Goro smiled, and placed his hand on Ren’s thigh. He felt the boy flinch under his touch, and it made his smile widen.

 

“Every good story has a plotline… a plot twist… a climax ,” Goro murmured, letting the last word hang seductively in the air as he leaned in closer, his breath hot against Ren’s ear. Ren’s breath hitched, and he stuttered, “Th-Thank you—I think I get it—”

 

But his words were cut short as Goro’s hand inched higher, creeping closer to where his thigh met his pelvis. Ren gulped audibly, his face flushed, his body trembling slightly. Goro’s fingers began to massage the fabric, and he felt Ren’s tent forming beneath the cloth. 

 

“Do you really?” Goro teased, his voice a low purr. “You have to pay attention. Go ahead, read this example story and find the mistakes in the text,” he commanded, pressing his body closer against Ren’s side.

 

Ren nodded, visibly shaking as his eyes flicked down to the paper. “The warmly lit room was—” His voice hitched again as Goro’s hand slid under his shirt, gloved fingers tracing the soft skin of his abdomen. “Continue,” Goro coaxed.

 

“It—It was, it was—” Ren’s voice faltered as Goro’s hand moved back lower, fingers brushing against the growing tent in his pants. “It was— ah—

 

A sudden knock echoed through the room, sharp and loud.

 

“Akechi, are you in there? I’m finished with my work,” Niijima’s voice called out from the hallway. Goro fought the urge to roll his eyes as he stood up, crossing the room to open the door. “Good job, Niijima. I was just supervising Amamiya-kun during his detention,” he replied smoothly.

 

Niijima nodded, glancing at the clock behind him. “I see. About that—apparently, the other boy confessed to starting the fight and wants to apologize to Amamiya-kun. So, he’s free from detention now.”

 

At her words, Ren shot up from his chair, knocking over his textbooks in his haste. His face was flushed, his breathing uneven, and his hands trembled slightly as he clumsily gathered his things. He looked disheveled, flustered, and more than a little panicked. “I-I have to get home, I’ll see you, Akechi-senpai,” he mumbled, slipping past Niijima with a clear bulge in his pants, fleeing down the hallway like a startled rabbit.

 

Goro couldn’t help the smirk that tugged at his lips as he watched Ren's hurried escape. How delightful. But just as he was about to leave himself, Niijima blocked his path, her expression stern.

 

“Akechi, don’t toy with our underclassmen,” she warned, her voice firm. “I know you’re responsible, and Ren Amamiya doesn’t deserve to be manipulated like that.”

 

Bitch. Who was she to interfere in his matters of discipline? What did she know about how to handle a misbehaving mutt like Ren?

 

Goro’s face remained calm, his polite smile never faltering. “I was simply supervising Amamiya-kun, Niijima. I’m not sure what you’re implying, but I do wish you a pleasant afternoon,” he replied, voice honeyed with innocence, before briskly walking past her, not sparing her a second glance.

 

He had other things to think about. He had more important matters to tend to. And Niijima would learn, just like everyone else, not to meddle in his affairs.

 


 

“With all due respect, I must apologize to everyone. Currently, our vice president is unable to attend school due to personal reasons. If you have any issues that need addressing, please direct them to Akechi Goro," Miss Kawakami announced. Her

exaggerated, sorrowful expression elicited a few sneers from students, but she carried on unbothered.

 

Ren frowned, puzzled. He had seen Niijima just the day before, looking perfectly fine. It must be a family matter–perhaps something serious enough to warrant a sudden leave.

 

Right. Just yesterday. When he had been alone with Akechi. The memory made Ren's cheeks flush with heat. Could Akechi have been... seducing him? The realization seemed impossible, but the memory of Akechi's touch, the way his hand had roamed, the whispered, provocative words in Ren’s ear–it all came flooding back.



Ren shivered at the thought. Since meeting Akechi, he'd never experienced such raging erection. The night before, as soon as he was home, he'd had an explosive orgasm, something he hadn't felt so strongly in a long time. Looking at the evidence on his hand, he felt something inside him snap. This wasn't how it was supposed to be.

 

It was meant to be inside Akechi, fuck him full of it. Fuck Akechi until he was a moaning mess. Akechi, he, who had clearly shown he wanted it as well. Ren had definitely been toyed with, and he wouldn't let it go. If Akechi wanted to play games, Ren was more than ready to play along. 

 

Two could play at this game, and Ren was determined to come out on top.

 


 

“Akechi-senpai!” A familiar voice called out behind Goro. He swiftly turned around, greeting Ren with a genuine smile, “Good afternoon,” he replied. Ren seemed a little out of breath, “The school’s over so–if, if you’re free, do you want to come over? I could make you some coffee and we can debate over the book we previously couldn’t.”

 

Goro mentally scoffed. Amamiya wanted him alone , at his home, huh? His little dog was getting a little too wild. How interesting.

 

“Of course, shall we head off?” Goro asked. Ren’s cheerful expression made him smirk. He was like a puppy after you had given it a treat.

 


 

The two of them stepped into a small coffee shop. From what Goro knew, Ren was staying under the care of a man named Sojiro Sakura, living in the attic above this very café. It wasn’t ideal for privacy, but it would do for now. Ren led him up a narrow staircase to a dusty attic. Though it seemed like the perfect den for a little mutt, it wouldn’t do for very long. Once Goro would have finally allowed his little pup to breed him, he’d make sure to keep him in his own apartment where he belonged.

 

“Sorry, you can sit here,” Ren said casually, gesturing to a worn-out couch. Goro nodded politely and took a seat. To his mild surprise, Ren sat directly next to him, their ankles brushing together. 

 

“Amamiya?” Goro asked, faking innocence and confusion.

 

Ren hesitated for a moment before explaining, “Ah, well… I read somewhere that if you’re closer to the person you’re talking to, it makes the conversation more honest.”

 

Of course. His little dog wasn’t planning anything mischievous—he simply wanted to spend time with him, pure and naive as always. Goro felt a small pang of disappointment but brushed it off. 

 

It’s fine. They were still alone. Ren was still his.

 

“I see,” Goro replied. “What did you wish to discuss specifically?”

 

Ren looked at him with an earnest expression. “Do you think the two main characters had sex at the end of the book?”

 

Goro nearly choked on his own breath. What kind of question was that? He scoffed. “Why are you asking me that? Did you want them to?”

 

Ren’s cheeks turned a shade redder, “I don’t know. I, uh…”

 

Goro seized the moment, his smile sharpening. “You don’t know much about this topic, do you?” The question seemed to catch Ren off guard; he blinked, looking genuinely puzzled.

 

“I shouldn’t really be discussing the topic of sex with you…” Ren muttered, his voice uncertain. Goro nodded, pretending to agree. “So, you’re just curious about what I know about intercourse, is that it? It wasn’t really about the book.”

 

Ren nodded again, his face flushed. “I just… I don’t think about these things much. My classmates often talk about stuff like this, but I’m always at a loss for what to say… So I hoped to ask for guidance, Akechi-senpai.”

 

Goro’s smile widened. How utterly delightful. His little puppy, so naive, so willing to be led. This was going to be fun. Ren was innocent, but Goro would never forget the lewd gasps he was making that day in the bathroom: roughly stroking himself while moaning Goro’s name over and over.

 

Let's make this even more interesting, Goro thought, a wicked smile curling on his lips.

 

With a sudden burst of force, Goro shoved Ren back against the couch, hard enough that the air rushed from his lungs. "Akechi-senp-" Ren started, but his words were abruptly cut off by Goro's hand clamping over his mouth. Without hesitation, Goro crawled on top of him, pinning him down. "Your caretaker is still downstairs, isn't he? Let your senpai teach you everything," Goro murmured, his tone dripping with false sweetness.

 

Ren gasped beneath him as Goro's fingers tugged his shirt up, revealing the smooth, untouched skin of his stomach. Goro traced his gloved fingers along the muscles, delighting in the way Ren shivered and squirmed beneath his touch.



"A-Ah, Akechi-senpai-Please, wait-" Ren stuttered, his voice a mix of pleading and need, but Goro had no intention of stopping. Not now. He finally had his little dog where he wanted him.

 

He gripped Ren's wrists, pinning them above his head with one hand, while his mouth descended to Ren's neck, kissing and biting with feral intensity. His knee pressed up between Ren's legs, rubbing against the obvious bulge in his pants, eliciting a deep moan from Ren's throat.

 

"I've seen the way you look at me, Amamiya," Goro whispered against his skin, his breath hot, "You want me, don't you? That question you asked... You wanted me to teach you, just like this." He sucked a bruise into Ren's pale skin, savoring the gasp that escaped Ren's lips, his hips grinding down almost involuntarily.

 

Ren was beyond words now, a mess of breathless sounds and desperate movements, his body trembling under Goro's touch. His hips bucked upwards, grinding against Goro's knee,

completely helpless and needy, like a dog in heat.



"I bet you've been dying to touch me, haven't you? Ever since we met, you've wanted to fuck me, am I right?" Goro's voice was low and teasing, every word dripping with cruel amusement as he watched Ren squirm and tremble beneath him.

 

"N-No... ah, ah -I did think that- ah , Akechi-senpai was attractive, but- gods -it wasn't just lust, I swear-" Ren's voice was breathless, broken by moans he could barely suppress. "I wanted to be near you, not just because of desire but because- mmh , you were more than just the president, you were so... interesting, so... I- fuck , please—"

 

Goro's eyes widened, darkening with hunger. He was going to devour his little puppy.

 

His hand traveled lower, grazing the waistband of Ren's pants, teasingly dipping just beneath the fabric. He felt the sharp intake of breath, heard the delicious little gasp Ren made as his fingers skimmed the sensitive skin-

 

"Ren! Come downstairs immediately!" A deep, commanding voice boomed from below.

 

Goro froze, his jaw tightening with frustration. So close. He could feel Ren stiffen beneath him, his eyes wide with panic. 

 

Goro reluctantly pulled away, releasing Ren from his grasp. Ren was a mess—his hair disheveled, shirt rumpled, his skin flushed a deep red, especially around his neck, which bore marks like he’d been mauled by something wild. Anyone with eyes could see exactly what had transpired.

 

Clearing his throat, Goro put on his sweetest, most innocent voice, his eyes fluttering with mock sincerity. “That was a wonderful discussion session, Amamiya-kun. I’ll see you at school tomorrow, won’t I?” 

 

He made a show of licking his lips as he stood, savoring the effect it had on Ren, who remained silent, still trembling with unspent desire, staring up at Goro like he was prey.

 

Internally, Goro was laughing. The thrill of having his little puppy so completely under his thumb, so easy to manipulate and tease, sent a shiver of satisfaction down his spine. Straightening his tie, he turned and began his descent downstairs.

 

“Ren, I told you to—” a man’s voice came from the bottom of the stairs, cutting off abruptly when Goro came into view. “Oh, you must be Akechi-san. I hope you don’t mind hanging out with my troublemaker,” the middle-aged man said, his tone a mix of apology and amusement.

 

Goro gave a polite smile, closing his eyes in that practiced, charming way of his. “Amamiya-kun is a very valuable debate partner, and a good friend,” he replied smoothly, every word laced with false politeness. Goro knew Ren was upstairs. Knew that he was listening. Goro made sure to loudly pronounce the word ‘Friend’. 

 

The man chuckled, nodding as he propped a hand on his hip. “I see. Well, then, I’ll see you around, Akechi-san.”

 

Goro smiled once more, a polite mask hiding the satisfaction curling inside him. As he walked away, he couldn't help but think how easy it was to tease his dog with a treat in his hand. Ren was like a starving mutt, clawing at Goro with the need to eat.

 


 

Goro sat alone in the student council room, the bright light reflecting the cheerfulness of his mood. Today, he felt especially content; yesterday had gone perfectly. He had finally managed to teach Ren a lesson. Amusingly, Ren had been avoiding him ever since, probably out of sheer embarrassment.

 

Goro's little pet was now thoroughly tamed. The marks on Ren's neck had sparked a flurry of whispers and gossip throughout the school; after all, the uniform didn't hide much.

 

As Goro continued his work, the door creaked open.

 

Without looking up from his papers, Goro spoke curtly, "I'm busy right now. Please come back later."

 

No response.

 

Irritation flickered across Goro’s face. He finally glanced up, prepared to send the intruder away with a thinly annoyed remark, but stopped short. It was Ren. His gaze was fixed on the floor, making it impossible for Goro to read his expression.

 

Goro's lips curled into a smirk as he watched Ren close the door behind him. "Good afternoon, Amamiya-kun," he teased. "Have you come for another discussion session?"

 

Silence hung in the air until Ren murmured something softly. "...up."

 

"What?"

 

Ren's voice was firmer this time. " Shut up. "

 

Before Goro could fully process the words, Ren strode over to his desk, looming over him.

 

"Amamiya?" Goro asked, his confusion evident. But he was stunned when Ren moved around the desk, grabbed him by the collar, and slammed him roughly against the wooden surface of his desk.

 

It happened too quickly for Goro to react. His chest was pressed against the wood, Ren’s weight pinning him down, holding him in place.

 

This position... it felt strangely familiar. It was like... a breeding position between dogs.



"I told you to shut up , whore," Ren hissed, effortlessly pinning Goro down with a single hand.

 

He slipped off his tie and swiftly wrapped it around Goro's wrists, binding them tightly together.

 

“Amamiya—what are you—" Goro's protest was cut short as two fingers were shoved into his mouth, Ren's other hand gripping his jaw with force. "What part of 'shut up' don't you understand?"

 

Goro's eyes widened in shock. Had Ren always been like this? The boy he knew was shy, almost timid-bold only in fleeting moments of their personal encounters. But this... This was

something else entirely. This was dominance.

 

And the realization sent a rush of heat through Goro's stomach.

 

Ren's hand wandered down, squeezing his ass, eliciting a moan from Goro. The fingers in his mouth thrust deeper, silencing him completely. 

 

"Look at you–so needy. I bet when I turn you around, you'll be hard and leaking, won't you? When I first met you, Goro, I thought you were some proper upperclassman. Turns out, you were just a pervert looking to lay your hands on me."

 

Goro squirmed, grinding his hips against the table. 

 

"Fuck... you were so special," Ren continued, his voice low and heated, "Your intelligence, your sharp mind... From the moment I met you, I wanted to fuck you. You were always so polite, so composed. It made me want to pin you down, to see that mask crack, to turn the perfect student into a whimpering mess beneath me." As he spoke, his hands moved to undo Goro's belt.

 

"And then, in detention, I realized what you did," Ren's voice grew darker, "I was shocked. Couldn't believe it. The perfect, polite president-just a desperate whore who wanted his lowerclassman to fuck him."

 

Goro whimpered around Ren's fingers, his body trembling with need. 

 

Gods, he was so hard.



"They say you're-fuck," Ren groaned, grinding his hips against Goro's boxers. "Friendly to most people here. Before I met you, were you desperately trying to get laid by your other underclassmen, hm?" His voice dripped with mockery as he spoke. Goro cried out, muffled by Ren's fingers, which were quickly pulled out of his mouth.

 

"Ah, ah, Ren-no-fuck, please, you're the only one. You're-ah-mine, mine, mine," Goro repeated, his hips bucking back in desperation, seeking friction. Ren moaned in response, enjoying the power he held over Goro as he laid him on his back across the table.

 

"I'm yours? That's right," Ren growled, his eyes dark with lust. "I'll prove it." In one swift motion, he tugged Goro's boxers down.



"Look at you," Ren sneered, his voice laced with venom as he wrapped his hand around Goro's length. "So hard and pathetic. All the girls drool over you, but your size? Not even that impressive." Goro choked on his own breath as Ren's fingers tightened around him.

 

"Fuck, you were made to be bred," Ren teased, stroking him faster. "Did you think you could satisfy a girl with this pathetic thing?" Goro shook his head frantically, overwhelmed by the intensity. He was too hard, too hot, everything felt too much.

 

"No, no, no, you're the only one- please, breed me," Goro gasped, his voice trembling with need.



Ren smirked, lowering his mouth to Goro's neck, biting down hard and sucking harshly, leaving marks as he went. "All the time I spent chasing after you," Ren murmured against his skin, licking the fresh bite marks. "It was almost like I was your dog."

 

Goro cried out, his body trembling as Ren's hand moved too fast for his comfort. The only lubricant was his own pre-come, and the rough friction

bordered on painful, yet it only made him want more. "Breed me like one, too -fuck!"

 

Ren's grin widened as Goro came, spilling over his hand. "Tell me, Goro," he said softly, watching the other's chest rise and fall in exhaustion. "Are you a virgin?"



For a moment, Goro was too breathless to respond. Then, slowly, he nodded, his face flushed.

Ren chuckled darkly. 

 

"Oh my, the all- too-friendly president, untouched? What an honor." His fingers slid over Goro's slickness, gathering up the release. "I'll make sure to mark you up properly-breed you into the shape of my cock, so you'll always remember who was your first."

 

With that, he lifted Goro's legs, the hunger in his eyes only growing.

 

"I-I've... fingered myself before," Goro admitted shyly, his voice barely above a whisper. Ren raised an eyebrow in surprise. "Oh?"

 

“I... I was thinking of you, so I—" Goro's confession was abruptly cut off by Ren's lips crashing into his, the kiss fierce and messy, filled with tongues and teeth. Neither of them had much experience, but the hunger in that kiss was unmistakable. It was like Goro had flipped a switch.

 

As their kiss deepened, Ren's hand drifted lower, a single finger circling Goro's entrance. Goro had done this enough times that the feeling of Ren's finger slipping inside sent a wave of warmth through him. It wasn't enough to make him hard again, but it was enough to make him whimper softly, his body clenching needily around Ren's

touch.



"Look at you," Ren murmured, voice low and taunting. "Sucking me in so greedily. How often did you fuck yourself thinking about me, hm? I should've bent you over the first time I saw you." He added a second finger, his other hand stroking Goro's semi-hard length.

 

"Ah, ah—often—every time we hung out -oh, Ren, please, please-" Goro's words tumbled out, desperate and pleading, unsure of what exactly he was begging for.

 

Ren laughed, his fingers scissoring harshly inside Goro, quickly finding that sweet spot that made Goro arch off the table with a sharp cry of pleasure. His cock throbbed to life again, almost aching for attention. Pathetic, Ren thought with a cruel smile.



After several minutes of relentless fingering, Ren pulled his fingers out with a wet squelch, earning an angry whine from Goro. He chuckled at the boy's neediness as he unfastened his belt, the tip of his cock teasing Goro's entrance. "Be a good boy while I breed you like the bitch you are," he growled, slowly pushing inside. Despite the teasing, he wasn't completely heartless -he let Goro adjust to his size.

 

Goro clung tightly to Ren's uniform, his body trembling as he cried and gasped for breath. Ren was bigger than he could've imagined, stretching him wide like a wild animal in heat.

 

"Shit, you're so tight. You're almost sucking me in," Ren groaned, his voice thick with arousal as he began thrusting slowly. "Is this what you wanted all along, huh?" 

 

Goro couldn't reply-he was too overwhelmed by the intense sensation of Ren moving inside him. That wouldn't do.



Ren slapped Goro's ass, the sharp sound cutting through the air. Goro cried out, his cock twitching in response. "What a little whore," Ren sneered. "Do you like it when I'm rough? Do you want me to breed you like a dog? Fill you up with my cum, make you carry my puppies, huh?” His words came out in heavy breaths, his pace quickening.

 

Goro trembled, his body shaking with the table beneath him. It was too much and not enough all at once. Ren's cock was hitting that perfect spot inside him, making his vision blur at the edges.

Ren slapped him again, harder this time. "Answer me."

 

"Yes, yes—ah! Fuck, please-breed me, fill me with your puppies, fuck—make me full of your cum!" Goro begged, his voice raw with desperation.



Ren moaned loudly, thrusting into Goro with reckless speed, on the verge of losing control. "I'll make you a mommy, yeah? Fill you up with my cum, make you give our puppies all your milk," Ren panted into Goro's ear, his breath hot against his skin.

 

"Yes, yes-ah, please, please-I want to be a mommy!" Goro cried, completely lost in the overwhelming pleasure.

 

With a final thrust, Ren came deep inside him, moaning as Goro's body clenched tightly around him, sending Goro over the edge as well. Their climaxes hit simultaneously, leaving both boys breathless and trembling. 

 

Ren slowly pulled out, his chest heaving as he took in the sight of Goro, completely fucked out.

 

Ren smirked to himself, mentally congratulating himself for lasting longer than most first-timers. But as he looked down at Goro's limp body, he couldn't

help but laugh softly.

 

Goro had passed out.

 


 

"You were such a fake jerk back then!" Ren teased, his voice muffled as he buried his face into the scent of his boyfriend's shampoo. 

 

"A jerk? How offensive, Amamiya," Goro replied with a smirk, his face pressed lazily into the pillow beneath him.

 

"Excuse me, what happened to 'Ren'? I've been balls deep inside you hundreds of times—use my first name properly!" Ren insisted. Goro let out a laugh, clearly just toying with him. It had been two years since they started dating, and their relationship had grown into something natural, something they both cherished. Ren had taught Goro how to truly live, how to break free from all the suffocating expectations.

 

"Yeah, yeah! You’re still a jerk," Ren continued, unable to resist pushing back. "You act all polite, but deep down you’re such a meanie. And you're definitely not polite in bed, not by any means—" Ren’s rant was cut short when Goro tossed a pillow into his face, causing both of them to burst out laughing.

 

It was domestic, it was comfortable. Outside the bedroom, Ren was soft, gentle—a good boy. And underneath the dominant façade, Goro knew Ren was still his eager little puppy. 

 

And Goro? He had learned how to discipline him, how to guide him—and Ren always responded with excellent results.

 

After all, a well-trained dog knows its master. And Goro was a very good master.
