Kinktober Day 1 - Aftercare | Ryuji Matsuyama x F!Reader

Kinktober 2025 Masterlist

Content Warning: Discussions of sex (nothing explicit), Ryuji considers eating you out to be part of his aftercare routine, implied age gap (Professor sleeping with one of his college students), insecurities from both sides, Ryuji is kind of absolutely smitten and incredibly obsessed with you (and you are pretty smitten right back), probably curse words since I have no chill; this is the fluffiest and tamest piece you will read in all of October so please enjoy

I won't tell anyone what or what not to do, but please interact responsibly ✨️

A/N – This is set prior to Ryuji’s car accident, and in my mind, this particular Reader is the student that offers to be injected with the drug to have a near-death experience for him. Ultimately she'll die, and be a catalyst for the accident in the first place. I may expand on this Reader and particular (heavily insane once his beloved is gone) version of Ryuji in other drabbles or stories!

You watched as raindrops slid down the classroom window, tracing uneven paths against the glass. The professor’s voice faded into the background, nothing more than a dull hum, as your thoughts wandered to the one person who had unexpectedly consumed your mind over the last few weeks.

It had started with curiosity. You’d always been the one to think past the surface, to dig deeper into subjects most people skimmed over. That restless need to know more was what led you to discover a paper written by Ryuji Matsuyama. The first line alone had hooked you. He had written about questions you’d wrestled with for years, ideas that felt like they had been plucked straight from the corners of your mind.

That discovery was one of the reasons you chose this university, because you’d learned he was teaching here. The very first chance you got, you approached him after class.

“I read your paper. It was fascinating.”

“You’re interested in mental illness?” he asked, hardly glancing up as he shoved his notes into his bag.

“Not exactly” you replied. “I meant the part where you wrote that stimulating a section of the temporal lobe can trigger near-death experiences.”

That made him pause. For the first time, he looked at you properly.

“You’re the only one here who’s ever brought that up.”

And just like that, you had his attention.

What began as quick conversations after class soon became a ritual. You stayed behind almost every day, tossing ideas back and forth until he finally suggested meeting in his lab from time to time. You hadn’t hesitated, only a fool would have said no.

Now, sitting in another lecture you barely heard, your mind drifted again. The thought of the lab, of the conversations waiting for you with Professor Ryuji Matsuyama, filled you with a quiet thrill.

The bell finally rang, pulling you out of your drifting thoughts like a jolt back into reality. Relief washed over you, you didn’t even bother pretending to listen to the professor anymore. You swept your notebooks into your bag with quick, practiced movements, eager to escape the monotony of the classroom.

It was already past six. Your stomach growled in protest, reminding you of the hours you had gone without eating. On your way to the lab, you decided to make a quick detour to the snack distributor near the stairwell. You hovered in front of the machine for a moment, scanning its limited choices under the harsh fluorescent light. After some indecision, you tapped in a number and watched the bag tumble down into the tray with a hollow thud. You bent slightly, fingers just brushing the wrapper, when a voice suddenly called your name.

You turned, startled, the familiar sound cutting through the quiet corridor. Standing there with a grin was Kenji.

“Hey” you greeted with a small wave, straightening as you retrieved your snack. Kenji was a classmate of yours, and more importantly, your partner for Ryuji’s final assignment. He was easy to be around, a little clumsy, but genuine in a way that made people naturally comfortable.

“Heading home already?” he asked as he approached.

You shook your head. “Not yet. I was planning on studying in the library before leaving.”

That was only half-true. Your evenings didn’t really belong to the library anymore, not when you had somewhere far more intriguing to be. While your meetings with Ryuji weren’t forbidden, not exactly, you both seemed to understand the unspoken rule of keeping them private. Whatever was growing between those quiet conversations in the lab, it was yours alone.

Kenji didn’t press. He just nodded and said “Then I’ll walk you there. I was heading that way anyway.”

The two of you fell into step, trading easy jokes and small laughter as the corridors thinned of students. By the time you reached the library, the halls were nearly empty, the quiet of early evening settling over the campus.

“This is me” you said, pausing at the library entrance.

Kenji gave a half-smile. “Don’t study too hard. See you tomorrow?”

“Yeah” you nodded, returning the smile before watching him walk off down the hall.

As soon as his figure disappeared around the corner, you turned to the right. The library’s heavy wooden doors stayed behind you as your feet carried you toward the lab instead. A faint nervous excitement hummed beneath your skin, like it always did.

The lab door opened with its usual creak, spilling a sliver of light into the dim corridor. Inside, the fluorescent lamps overhead had been left off, only a desk lamp glowing faintly somewhere deeper inside the room. The shadows stretched across the tables and glass cabinets, giving the place a hushed, almost secretive atmosphere, which made you assume Ryuji hadn’t arrived yet.

You slipped further inside, the door clicking shut softly behind you. From your bag, you pulled out the white blouse you kept just for these visits, slipping it on over your clothes. A ritual by now, it felt almost symbolic, as though putting on that blouse set you apart from the rest of your student life. You reached up to tie your hair, movements casual, your mind already rehearsing what questions you might bring up tonight.

Then you flinched.

At the edge of your vision, you noticed a figure seated at one of the desks. The faint scratching sound of a pen against paper reached your ears, so subtle you hadn’t noticed it at first.

Ryuji’s eyes met yours across the dim lab, the glint of the desk lamp reflecting in his gaze.

You let out a soft chuckle, trying to ease the tension clinging faintly to the air. “You scared me.” you admitted, exhaling.

Ryuji leaned back slightly in his chair, pen still in his hand. “The lights are out” he explained simply, nodding toward the dark ceiling fixtures. “For tonight, desk lamps will have to do.”

You gave a small sigh and nodded in understanding, the pale glow of the lamp casting both of your faces in an amber haze. Pulling the rest of your hair into a quick knot, you walked toward him and slipped into the chair beside his. His notes lay scattered in neat disorder across the table, ink marks, underlined words, diagrams that looked sharp and meticulous. You leaned a little, curiosity tugging at you.

“Have you been thinking about anything new?” you asked, eyes flicking from the papers to his profile.

But his gaze didn’t land on you. Instead, his eyes moved restlessly, shifting from the microscope to the notebook, from the pages back to the lenses, only occasionally darting in your direction before sliding away again. There was something deliberate in the way he avoided meeting your stare, but you didn’t press. At least, you tried not to.

“Can I see ?” you asked after a beat, nodding toward the microscope.

He didn’t hesitate, just leaned his chair back a little, leaving room for you. You turned the eyepiece gently, lowering your face until the world narrowed into the circular field of the lens. The familiar branching lines and structures came into focus, and you recognized it almost instantly.

“Wait, this is one of the subjects for the final assignment, isn’t it?”

Ryuji’s voice came quietly, almost matter-of-fact. “It is.”

A smile tugged at your lips, and you pulled back slightly from the microscope. “Then I’d better get an A on this after everything,” you teased, trying to bring some levity into the dim-lit atmosphere.

He gave a faint breath, not quite a laugh. “If you were doing it alone, there’s no doubt you’d get an A.” He paused, eyes lingering on his notes before adding, “That’s why it’s important to choose a good partner.”

Something in his tone, too sharp, too pointed, made you still. The air between you seemed to shift. Slowly, you leaned back into your chair, turning your head to look at him properly. His gaze was finally fixed on you, steady and unflinching, almost heavy with an intensity that made your stomach dip.

For a moment, neither of you said anything.

Then, as though nothing had happened, he reached forward and replaced the plate beneath the microscope, his movements smooth, calculated. He bent slightly to peer back through the lens, leaving you to blink the weight of his stare off your skin.

“My partner’s Kenji” you said after a beat, forcing the words into the quiet. “He’s actually a really good student—”

“He failed the first test last week.” Ryuji cut in abruptly, his voice low but edged. The interruption was so quick, so decisive, it felt as though he’d been waiting to say it.

The silence that followed pressed down heavier than the shadows of the lab.

You tried to smooth the edge of his words with a light tone. “The test was really hard, though. I mean, half the class looked like they were drowning—”

Ryuji didn’t let you finish.

“You got an A” he said flatly, not even looking at you as he stacked his papers into a neat pile. “And the class average was an 80. It wasn’t hard.”

You blinked at him, caught off guard by the sharpness. You pushed back gently, trying to defend Kenji.

“Okay, but a first test doesn’t mean much. It’s the beginning of the semester, people are still adjusting—”

Again, he cut you off.

“If he spent his time with you wisely instead of laughing around, he probably would’ve passed.”

The sentence landed like ice water down your spine. The tone of it, the dismissal, the cold finality in his voice, it made you freeze in your seat. His gaze flicked up at you then, just for a moment, a piercing look that felt too heavy, too sharp, before he dropped it back down to his notes.

Silence stretched out between the two of you, thick and suffocating. The soft hum of the desk lamp was the only sound that filled the lab. You opened your mouth to speak, to maybe shift the atmosphere back to something lighter, but nothing came out. The weight of his words had shut you down.

Ryuji exhaled, long and tired, as though whatever thread of patience he had left had worn thin. He began gathering his notes with precise movements, stacking and sliding pages into his bag, the click of his pen echoing too loud in the stillness.

“I have a lot to do,” he said, voice lower now, though not softer. “I need to get home early.”

You sat there, dumbfounded, watching him. His behavior was so unlike him, so distant, so curt. This wasn’t the man who stayed after class to hear your thoughts, who leaned in when you spoke like your words carried gravity. It felt like you were staring at a stranger wearing his face.

He stood, grabbing his bag, stuffing it with his notes. Something panicked sparked in you, if you let him leave like this, you weren’t sure what would happen between you after tonight.

“Wait” you blurted, your hand darting forward before you could stop yourself.

Your fingers landed on his, stilling his movements as he slid the last folder into his bag. The warmth of his skin under your palm made your pulse skip, and for a second, he froze, too, his posture rigid. The world seemed to contract around that single point of contact.

Then reality crashed over you. Heat flooded your cheeks, and you recoiled, snatching your hand back as though you’d touched a flame.

“I—sorry,” you stammered, your voice quiet, breaking the silence like brittle glass.

He didn’t say anything for a long while, and the silence pressed down on you like a weight. His hand lingered on his bag. Then finally, his voice broke through, low and measured.

“You shouldn’t do that.”

The words weren’t sharp like earlier, but they weren’t soft either. They carried something heavier, a weight that slid down your spine and made your chest tighten. You lowered your gaze instantly, the sting of embarrassment settling in. You had acted before thinking, reaching out like that, breaking a line that should’ve never been crossed.

But before the shame could sink too deep, Ryuji sighed. You heard the faint rustle of his bag as he let it fall back onto the desk, his posture shifting. When you looked up, his eyes were on you at last, steady and unwavering. He exhaled slowly, as though the words that followed had been coiled inside him for too long.

“You’re smarter than the rest of them” he said. His voice wasn’t clinical now, not the detached tone of a professor. “Braver, too. That’s why you caught my attention.”

Your lips parted, breath stalling as the weight of his admission pressed into you.

“You should stay with people who share your interests,” he went on, the intensity of his gaze pinning you in place. “Otherwise you’ll waste your potential.”

Something in your chest twisted. Your whole body went still, your eyes lifting to his. A dozen questions burned in your throat, but none of them could take shape. The air between you was thick with things unspoken.

And then, quietly, you asked, “Do you mean yourself?”

The question cracked the silence like glass.

Ryuji scoffed, shaking his head, though his expression gave nothing away. “I’m your professor, not your partner.”

The dismissal stung, but before you could react, he added, almost reluctantly, “Do what you want. But I’m warning you.” His voice was low, deliberate, like a shadow curling around the edges of his words.

He reached for his bag again, shifting his weight as though ready to leave. But you moved before he could step past you.

“Wait.”

Your voice came out firmer than you expected as you pushed off the desk, stepping into his path. He stopped short, standing directly in front of you now, only inches of space separating you. His height forced you to tilt your chin up, your pulse loud in your ears.

He didn’t move, didn’t step back, just looked down at you with that same unreadable expression.

“You really don’t have to worry about Kenji” you said softly “He’s just my partner. If he struggles with the material, I'll be there to help him.”

Ryuji’s expression didn’t change at first, but you caught the flicker of something in his eyes. A shift, quick and raw, before it was shuttered again.

You went on, unaware of the storm tightening around him. “As you said, I'm smart, so a few private sessions at the library will get us an A.”

That was it, the last thread of his restraint snapped.

The bag slipped from his shoulder, hitting the floor with a dull, heavy sound that startled you into stillness. Before you could even ask what was wrong, his hand was on your jaw, the grip firm, tilting your face upward.

And then his mouth was on yours.

It wasn’t careful or measured, nothing like the precise man who lived in his notes and microscopes. It was forceful, searing, as though every unspoken thing inside him had been set on fire and you were the only way to put it out.

Your back hit the bookshelf hard, his body caging you in, his hand holding your face as though he was afraid you’d vanish if he let go. His kiss was fierce, demanding, almost angry, yet underneath it all there was a raw yearning that made your knees weak.

The moment his lips touched yours, everything you had told yourself about Ryuji being untouchable, distant, impossible, everything you had forced yourself to believe, shattered.

You melted into the kiss instinctively. Your hands lifted, fingers tangling in the back of his shirt almost without thinking, drawn to the heat and intensity of him.

When you responded fully, leaning into him, letting yourself be consumed by the kiss, he moved without hesitation. One hand slid under your knees while the other gripped your back, lifting you off your feet effortlessly.

Your breath hitched in surprise, but he didn’t pause. He carried you toward the lab desk, sweeping the notes off the desk in one quick, careless motion, sending them fluttering to the floor as he lifted you onto the surface.

He hovered above you, the desk lamp casting stark shadows across his face, highlighting the intensity in his eyes. His lips left yours for just a fraction of a second, enough for you to catch your breath, before pressing back with the same urgent, commanding force.

Your hands rested on his shoulders, trying to anchor yourself against the storm of feeling that had erupted between you.

As he pulled back slightly, leaving a trail of feather-light kisses along the curve of your neck, a slow, triumphant smirk spread across your lips. You had him exactly where you wanted, just as you had from the very moment you first read his paper. From that first line, you had known him, passionate, brilliant, untouchable… and perfect.

He was more than just desire ; he was restraint and discipline, a respected professor, and that made breaking him far from easy. But that's where Kenji came in handy. You had nothing against him, he was kind, funny, easy to be around, but he didn’t share the obsessions, the depth of conversation, the intensity you shared with Ryuji. With Kenji, there were limits. With Ryuji, there were no limits you weren’t willing to explore.

Your gaze drifted to the lab window now covered by curtains, hiding the food distributor across the hall from which you had seen Ryuji standing earlier before you came, watching people pass by with that quiet, calculating look.

When, at that moment, Kenji’s voice called out behind you, you’d felt a spark of wicked amusement. You’d turned, putting on your widest, most disarming smile, knowing Ryuji would see every gesture, every laugh. You’d played your part perfectly, subtle and teasing, planting a seed that would rattle him just enough.

Over the past few lab sessions, you had noticed the small, deliberate ways he had let his control slip, lingering touches that brushed against your skin, words that carried double meanings, gazes that followed you longer than propriety demanded. You had recognized the signs, calculated them, and known this would be the tipping point. Kenji had been the perfect catalyst, innocently oblivious, just enough to provoke the storm that had been building beneath Ryuji’s composed exterior.

And now here you were. His lips moved lower, tracing your neck, your shirt partially unbuttoned, exposing skin that had been shielded from the world until now. His hands were bold, daring, sliding under your skirt, tracing upward across your thighs with a possessive urgency that made your breath hitch. Every touch, every press of his lips against your skin, pulled you deeper into him, intoxicated and dizzy with desire.

You wanted him entirely, just as he wanted you entirely. The boundary between student and professor had dissolved, leaving only two people locked in the same fevered hunger, feeding off each other’s intensity. You moved instinctively, arching slightly as his hands explored, letting yourself be claimed by the man who had always fascinated you, the man who had challenged your mind and now your body.

You were one with him. Every stolen touch, every sharp gasp, every racing heartbeat drew you closer to a truth you had known all along : that this moment, this surrender, was exactly what you had been building toward since the moment you first read his paper. The rest of the world fell away. Kenji, the assignments, the lectures, they were all just background noise to the storm that existed between you and Ryuji, and nothing else mattered.

This was the culmination, the game you had been playing from the very beginning, and that you won.

(Pt1 of 4-5)

You stood next to Rei as the smoke cleared. Arisu’s plan had just led the group to success once again. Everyone reaching to take off the mask and preparing to head to the next cart. 

“There's another train coming!” you had heard someone scream from a distance. It was faint, mostly covered by the loud sound of the train.

You turned your head back to see Arisu staring at something-or someone on the otherside of the train, eyes wide in what seemed like horror..? 

“ARISU!” someone screamed from the train across from you guys. 'Wait- another train?' you thought. Everyone's heads turned to see who had screamed and where it came from.

The woman who had screamed out was trying to reach Arisu, arm extended forward as she clutched the doorframe.

Arisu quickly tried to reach out as well, but the distance was to wide.

Both you and Rei moved towards Arisu for a better view of the commotion. The two of you hanging onto the handles of the train, trying not to fall out.

You and Rei had been together since the first game. You were like the elder sister she had always wished for while she was the younger sister you had always wanted.

From what you could see, the woman reaching towards Arisu had short hair and was dressed in a white shirt; She had almost perfectly matched the description Arisu had given of his wife and looked like the woman in the tape the police showed you after your husband had gone missing. Usagi.

Authorities questioned the possibility of an affair between the two. You tried to defend him, but the evidence was overwhelming, both having gone missing together at a hotel, and Ryuji having a rather concerning obsession with her.

You looked over to see the rest of the group on Usagi's team. Your eyes scanned everyone on that train until they landed on a familiar face who was already staring at you with their eyes blown open. You felt yourself freeze entirely as you stared at them.

It was Ryuji, your husband, the man who promised to never leave you and to love you in sickness or in health, like you did for him.

For some reason, he was out of his wheelchair and lying on the floor of the cart. Your head started to race with concern, and your heart rate sped up the more you two stared at each other. 

Rei turned to you as she had noticed you freeze, “You ok onee?” she asked with her eyebrows furrowed. You just absentmindedly nodded before realizing the trains were being split, and both Usagi and Arisu could injure themselves gravely.

You didn't even process your quick movement as you launched to pull Arisu away from the cart's door. Ryuji doing the same with Usagi. 

Your head pounded from the noise, your stomach doing what felt like backflips from all the shit happening around you. 

Both teams watched each other from farther and farther away as the trains rushed towards different locations. Soon, the two trains were cut off entirely by walls, and the noise quieted. You tried to catch your breath as Rei laid her head on your shoulder.

“She was with a guy,” Tetsu spoke, “Hey!” Sachiko discouraged before hitting his shoulder lightly like a mother telling her kid to knock it off.

Your heart dropped at that sentence. Your wedding ring suddenly feeling heavy. Could he really have been cheating?

Deadly Curriculum

It was a quiet afternoon. You play with your pencil, quietly zoning out from your professor’s teaching. Could the Borderlands actually exist? Why are games played to survive? Who else believes in it?

Your internal questioning was shortly stopped once the bell rang, signaling that class was over. However, you had more important things to do than attend your seminar class.

You had read your professor’s research about near-death experiences; it fascinated you. Where did he get this information from? Did he experience it himself? Was it after his car accident?

Ryuji Matsuyama was his name. After the death of his student, no one really wanted to be near him. They believed he was insane, that he shouldn’t have been allowed to continue teaching. Yet, here he was. Standing in front of you, only focused on gathering his papers.

“Excuse me, Mr. Matsuyama,” you say softly. “I have a few questions.”

“Regarding what,” he states, continuing to shuffle his papers.

“Regarding your research on near-death experiences and the Borderlands,” you assert.

Ryuji Matsuyama stops shuffling his papers. It’s as if his whole world stopped, because it basically did. Someone being interested in his work instead of avoiding him? Another student at that?

He looks up at you. This causes you to falter a bit. His eyes were dark and looked void of everything and anything. His stone cold face left you wondering if you said something wrong or if you piqued his interest.

“Why do you care. I barely know your name and you probably know about my last interaction with a student. Nothing for me to share with you. You’re dismissed,” he asserts.

You watch as Mr. Matsuyama wheels himself out the door, turning his back without a single ounce of hesitation.

“Asshole,” you exclaim. You thought he wanted someone to ask about his research, let alone show a ounce of interest in it. Yet, here you were. Alone. The quiet. Empty. Nothing. Your questions would never be answered; or so you thought.

As Ryuji wheeled himself out, it took every part of him to not drag you to his office and share all of his research, including interviews with survivors, to you. He didn’t want this to be another accident. Another loss of a student. Another suicide mission. Another failure. Another part of himself loss to the void of nothingness.

A few days later as you sit in class, you stare at Mr. Matsuyama intensely. You refused to let your questions go unanswered. After the death of your sister from the Shibuya meteorite incident, you’ve been wondering about what happened in her last moments. After your research on the Shibuya incident, you saw an article about the “Borderlands”. What did it all mean?

Once you entered Shushikan University after your last year in high school, you’ve spent the last four years researching about the border between life and death. Who knew that you’d learn about your psychiatry professor’s research spanning years? You wanted—needed, to know what happened in that one minute your sister’s heart stopped, leading to her passing.

Zoning out once again, the bell’s ringing wakes you up. Once you realize you’ve been unintentionally staring at your professor, your gaze was met with reciprocation from your professor.

His eyes: Dark. Void. Nothing. Lonliness. Curiosity. Desire. You were determined to find out the truth; opening Pandora’s Box once and for all.

As Ryuji wheels himself out, you follow behind him.

“Professor!!”, you exclaim. “I need to know, and I need to know now!”

“Know what,” he said nonchalantly.

“You know.”

“Do I?”

“What. are. the. Borderlands,” you assert.

Ryuji Matsuyama wheels himself around to face you. He looks at you up and down, internally contemplating whether or not he should risk it all again and tell you. But the again, what is there to risk anymore?

“Follow me. Now,” he states as he turns around and wheels himself to his office.

You quickly follow behind, not knowing that this would be the beginning of a dark end.

As you enter his office, you are quickly greeted by stacks of papers and post-its, illustrating his deep devotion to his work.

You look around, simply gazing over articles and documents on near-death experiences and the afterlife. Ryuji gestures for you to join him at his desk, and you oblige.

“These are all the documents of survivors from the Shibuya meteorite incident, the one place where multiple people must’ve experienced the Borderlands. Here are interview clips too,” he states.

You skim through the survivors, immediately recognizing two of them: Ryohei Arisu and Yuzuha Usagi. They were the two people your professor was speaking to in the lobby.

“Do they remember anything that’s happened?”, you ask.

“Arisu doesn’t. Usagi…” Ryuji abruptly stops. You notice his interest in Usagi, believing that she must remind him of his dead student.

“There’s a ‘seminar’ coming up. It’s at the Koto Side Office on Tuesday. If you want to have a near-death experience, I’ll pick you up to take you,” he says.

Ryuji stares at you intensely. A hint of worry glides across his face, yet you do not notice. “This is your chance to back out. Because once we attend, there’s no going back.”

“I need to know what happened to my sister. I must experience the Borderlands. I can’t continue to live my life in solitude. No one understands. If it means dying, then I must die,” you assert.

Ryuji slightly grins, looking away as he takes a sigh, then looks back at you. You’ve piqued his interest, not just academically, but personally. A professor taking interest in his student? Despicable. Yet, you were basically offering yourself right up to him. You admired him. Besides your curiosity, you wanted him. His mysterious persona, his cool and collectiveness, it drew you in.

“Professor…”, you say softly. “Before we attend the ‘seminar’ and potentially die, do you think we could go out for drinks sometime?”

Ryuji Matsuyama looks up at you with interest. “Please, just call me Ryuji. If we’re going to basically kill ourselves we should call each other on a first name basis,” he states.

“Right, okay,” you say.

“But yes. I would like to have a drink with you,” he states.

You both stare at each other. Gazing into one another’s soul hoping to find something that says back away. Yet, to no avail.

It’s no secret that you’ve had interest in Ryuji. Ever since your first year attending Shushikan University, you’ve seen him around. Whether he was walking, or now wheeling. Being an assistant of the psyciatry department, you saw him around all the time. Did you speak to him very often? No. Only when you wanted to know what was for lunch, which to your dismay, he often said, “I don’t know.”

But being that he became your professor for your third and now last year attending the university, you were attracted to him even more.

Three days later, you decide to meet up with Ryuji for drinks. A celebration, yet final moment between the two of you, considering that the “seminar” would take place the next day.

As you walk into the bar, you spot Ryuji sitting at a corner table, already placing orders for drinks and meals.

“Hey professor. Sorry, I mean Ryuji,” you say in embarrassment.

“That’s alright. It’ll take time. Call me whatever feels comfortable,” he states as he takes a shot of alcohol.

“‘Seminar’ is tomorrow. Might as well spend our last potential moments with good thoughts in mind, no?” He says, watching you as you take off your jacket.

Ryuji takes a deep sigh in. He clenches his fist under the table. Waiting. Watching. Wanting. Needing.

“I agree. I just… never thought I’d get so close to finding out the truth of what happened to my sister. What she went through in the Borderlands…” You whisper.

Ryuji looks down at the table, then up at you again.

You feel his gaze. He always knew how to make deep eye contact. It made you feel vulnerable, so very vulnerable.

“What’s wrong?” He asks.

“Your eyes. Sir, they make me feel shy.” You manage to mutter out.

“Oh? Is that so?” He whispers, continuing to watch you, but now it seems his gaze intensifies.

You try your best to keep up, you really do. But because of his curiosity of your character, or his pervertedness—because you really can’t tell—you decide to look up at him slowly, finally reaching the eye contact he waited for. He longed for.

So, is this how you ended up in his office? Watching him take off his shirt, leaving his bare muscular figure on show? Is this how you ended up on his lap, kissing him with hunger as his hands reached for your waist? Maybe. Or maybe it’s because you’re just a really perverted person who finds Ryuji Matsuyama hot. Perchance.

You kiss Ryuji with passionate hunger as he returns the favor. You hold his neck, tongues connecting as you taste the shots of alcohol he had earlier. It was all dizzying, so mind-inducing.

He pulls back from the kiss, the look of hunger and lust now fills his eyes.

“Do you have any idea? Any idea how much I was holding back?” He says.

“Do you know how many times I’ve fucked my hand imagining you doing it for me? If I knew you were this much of a whore for your professor I would’ve fucked you in front of everyone quickly. I need to meet your needs don’t I?” He groans at that last sentence.

You are stunned. Completely stunned. Your own hot professor wanted you this whole time? Must be a dream.

“I need it, so badly. Please.” Your voice cracks in desperation.

“Bounce on my cock while you look at me. Now.” He demands with such nonchalantness.

“Y-yes, Ryuji.”

“It’s professor. Be a good student and show me how bad you’ve wanted this.”

You unzipp his pants. His eyes never leaves yours as you unzip your pants as well, disregarding them on the floor.

You get on top of Ryuji, sinking down onto his length as you whimper in the delightful stretch.

Your professor may have been average size, but he was wide, wider than anything you’ve ever had.

“Please. Professor. S’ big. I c-cant.” You mewl.

“Take it all. How can you survive in the Borderlands if you can’t even take all of my cock? I’m starting to think you’re not meant for this.” He slyly remarks.

You begin to move up, then slam back down on his length as you cry out in the stimulation. Ryuji lets out a small groan, with a grin of satisfaction.

You begin bouncing up and down on his cock, your eyes never leaving his. The sounds of your slick fills the office. A ring of your cream coating the base of his cock.

Ryuji’s hands begin to hold your thighs, forcing you to bounce even harder as you moan in pure delight.

“G-gonna take it all right? Be so good f’me.” He whispers, covering up his small whimper of pleasure.

You hear this, and grin. Your stone-cold professor just whimpered?

You hold his throat, slamming up and down on him, feeling his cock twitch inside of your warm walls.

“Gonna use you for my pleasure, professor. Take what I want for m’self, yeah?” You whisper in his ear.

Ryuji’s eyes falter onto your boobs spilling out your tank top. He whimpers in response, realizing that you cracked him open. Poor thing, he just really wanted love.

You can feel yourself getting closer and closer to your climax, and you’re sure he can feel it too by the way you squeeze on his cock.

You slam onto him three times more, leading to you cumming on his cock as he fills you up with his seed. You rest your head onto his shoulder as you catch your breath.

As you look up at him, you see a hint of softness in his eyes.

“That was really good. T-thank you.” He mutters.

“Who said I was done?” You answer back.

Ryuji has a confused look on his face as you get off him to then sit on his office desk.

“I want more. How can I be ready professor if you don’t give me more?”

Ryuji chuckles, as he wheels himself towards your legs.

He licks a stripe up to your puffy clit. Ryuji eating his own mess out of you? Atrocious, yet not to you. Not to him either.

He holds your legs open, with ease. All of the push-ups he’s done has really helped. He sucks on your clit as he uses two fingers to fuck your pussy. His seed acting as lube makes it easy for his fingers to slide in and out, causing erotic sounds of your pussy doing most of the talking.

“You’re so eager, yeah?” He says as he whimpers into your cunt.

You realize he’s not actually talking to you, rather your pussy as his lips indulge in licking and sucking on your clit, his eyes never leaving yours as he watches what makes you write in pleasure.

As he sits back up, mouth covered in your slick and his seed, you can see the evident effects you made on him again.

You straddle his lap again, catching him by surprise. You bring your hand up to his mouth, waiting for him to spit. He catches on, yet spits on his cock instead of your hand.

You slap him for that, as he groans in pain yet pleasure. His bad, he thought he’d make the job easier for you.

He watches as you use one hand to stroke his length, stroking from tip to the base, with one hand in his mouth. If he knew his student was this much of a whore, he would’ve called you to his office ages ago.

You stroke up and down his length, playing with his balls as you press on that one sensitive spot at the underside of his tip. He moans because of this, eyes rolling in the back of his head as he holds your waist.

You begin to rub circles on this sensitive spot, watching as pre-cum spills out the small slit and slides down to his balls.

“You like that, don’t you professor?”

He nods, drool spilling out his mouth as you fasten your pace on his length. He begins to moan louder, watching you as you play with him. He likes that.

You stroke for a few more times before his cum spills out, soaking his balls and your hand. His moans louder and more higher pitched than before as his mouth widens from the pleasure.

Ryuji catches his breath, slightly grinning as he kisses you passionately. His eyes are still dark, yet more cunning as he watches you lick his cum from your hand.

You help each other clean up, putting your clothes back on as you reach for the door.

“Wait. If we do end up passing the Borderlands, would you like to… formally continue our relationship. Maybe even more?” He asks.

“Yeah, I would love that.” You smile and nod.

You both know that Ryuji has no intention of returning to your world, considering his obsession with death and what happens after. Yet, you both like to hope. Pretend at least. Maybe once you both enter the Borderlands, there’ll be something in someway to draw you both closer as you relish in your last moments before death draws Ryuji closer.

Who knows, maybe you’ll join him on the other side.
