a/n: heyy!! this is my first post here, so I'm a bit nervous, but I hope you all like it. any feedback is welcome, I'd really appreciate it <3 happy reading.
You walk into the lecture hall on your first day of the semester and choose a seat near the exit because you’re not expecting anything special from an Advanced Ethics class—until the door opens and Professor Park walks in.
He looks almost too young to be a professor, yet he carries an intriguing air of authority. The moment he begins to speak, introducing the course in a low, calm voice, you’re instantly hooked. Something deep in your stomach twists with sudden heat.
You spend the entire class staring at him, barely able to take any notes. He doesn’t smile once during the introductory lecture, and there’s something magnetic about it. He doesn’t seem to care about being liked by his students—he’s simply there, doing his job with strict discipline.
You’ve never been attracted to a professor before, but there’s something about him that captivates you instantly. Maybe it’s the way his biceps flex when he gestures while explaining something, or the fact that he seems almost too cold and professional.
By the end of the class, you feel an intense wave of jealousy over the measured praise he gave to other students. You want him to praise you. You want him to notice you. You want to be his favorite student.
Later that same day, back in your dorm, you make your first diary entry about Professor Park:
"Today I met Professor Park and my God, he’s so attractive. The way his thick eyebrows furrow when he’s explaining something… it honestly got me a little wet. I’m going to try to get his attention in the next classes."
You start sitting in the front row from that day forward, taking real notes and listening attentively to everything Professor Park says.
Throughout the week, you write more entries in your diary:
"God, the way his voice drops when he’s explaining something… I keep imagining him using that same low tone while he tells me exactly what to do on my knees. His hands look so big, with those long fingers. I wonder how they would feel gripping my hips or squeezing my thighs…"
"I want him to bend me over the desk after everyone leaves, lift my skirt, and fuck me hard. I’d stay so quiet for him… or maybe he’d fuck me even harder if I moaned his name out loud? Either way, I just want his cock to stretch me open."
By the end of the first week, he already knows your name because you answer a question correctly in class, where he simply replies with a neutral "Correct," but it’s enough to make your stomach flip.
Still, you want more. Knowing your name isn’t enough — you need all of his attention. So you decide to try something new in the second week.
────────
You wake up earlier to put extra effort into your makeup and outfit. For your first attempt, you go for something natural — soft mascara, a light blush, and a touch of lip gloss. You pair it with a blouse with a subtle neckline and a medium-length skirt that falls just at your knees.
Sitting in the front row, you raise your hand several times, making intelligent and well-thought-out comments because you actually studied for it. When you do, you receive a "Good point" from him, accompanied by a small approving smile. It’s enough to make your heart race.
In the next class, you try a bolder look — eyeliner, a proper lipstick instead of gloss, and a bit of contouring. He glances at you during the lecture, but he doesn’t compliment you. His expression remains neutral. When you make another smart comment, he simply nods. The conclusion is clear: he prefers the natural look, so that’s what you stick with.
Now it’s time to experiment with clothing. The following day, you wear a revealing outfit — a blouse cut low enough to show your collarbones and a shorter skirt that reveals your thighs. Professor Park’s eyes linger a little longer on your cleavage and bare thighs. It’s not obvious, but you notice. Cleavage and shorter skirts seem to work better, so you start leaning into that.
You keep pushing yourself — spending hours studying, pouring everything into every assignment, arriving early to class in hopes of catching a moment alone with him, craving his praise like it’s oxygen. With each passing class, your blouses get tighter and your skirts get shorter, exactly the way he seems to like.
Your efforts are paying off. His compliments come more frequently now — "Well argued" and "You captured the theme perfectly" — making you press your thighs together under the desk.
During one lecture, you participate actively, offering solid arguments and sharp answers, earning even more praise from Professor Park. When the class ends, he stops beside your seat. His gaze drops to your breasts for half a second before returning to your face.
"You’re showing great improvement," he says.
It’s enough to leave you soaked.
That night, your diary entry is filled with need:
"He looked at my tits today. He really looked. God, I want him to praise me while he wraps his arms around me and squeezes me so tight I can barely breathe. I’d call him Daddy so easily — actually, that’s what I’m calling him from now on. I want to be Daddy’s favorite. I’d let him fuck my ass if that’s what it takes to be his good girl."
────────
After your morning class, you’re walking down the corridor when you spot him near the faculty offices, carrying a tall stack of papers and wearing glasses. Now you have a new fantasy — getting fucked by him while he’s wearing those frames.
You quicken your pace, pretending to be focused on something on your phone, and then "accidentally" drop your notebook right in front of him. "Oh no…"
You quickly drop to your knees, letting your short skirt ride up even higher. The view you give him is perfect: you on your knees, looking up with a submissive gaze, lips slightly parted, your breasts nearly spilling out of your low-cut blouse.
His crotch is right in front of your face. The fabric of his pants stretches tightly over the heavy outline of his bulge, the thickness clearly visible. This is exactly what you would see if you were sucking his cock. The fantasy of pulling that thick cock out and taking him down your throat while looking up at him with innocent eyes makes you shiver.
Professor Park makes no effort to help you up. He towers over you, his thick eyebrows furrowed in a rare expression of surprise on his usually neutral face. "Are you alright?" he asks.
Your eyes travel from the bulge right in front of you up to his face. You pick up the notebook and look up again from that perfect blowjob angle, whispering softly, "Yes, Professor. I’m just so clumsy sometimes."
For half a second, his gaze drops — taking in your glossy lips so close to his groin, the way your skirt has ridden up, and how your breasts look even more prominent from this angle. He clears his throat and forces his attention back to your face. "Be more careful next time."
You smile sweetly and finally stand up, tugging your skirt down even though it barely covers anything. "Thank you, Professor Park."
Your panties are soaked and your mouth is watering, the image of his bulge so close to your lips still burned into your mind.
He gives you one last lingering look before walking past you. If he had stayed even a second longer, you might have noticed the growing, hardening bulge in his pants.
That afternoon, you write in your diary:
"Holy fuck, I was literally on my knees right in front of him, exactly like I would be if I were sucking his cock. I wanted him to pull it out, grab my hair, and make me take every inch of that heavy length down my throat. I’m so wet just remembering how tall he looked standing over me. Please, Daddy… notice how desperate your good girl is."
────────
As the students begin to leave when the class ends, you deliberately take your time packing your things, hoping for another interaction with Professor Park. It works. He starts walking toward your seat and stops beside it.
"Miss, stay after for a moment," he says.
"Yes, sir," you reply. Your mind immediately wanders — imagining him locking the door, bending you over the desk, his strong arms pinning you down while his cock finally stretches you open as he calls you his "good girl."
Once the last students are gone, you walk up to him on shaky legs, your panties soaked and your nipples hard, clearly visible through the thin fabric of your tank top.
"Yes, Professor?" Your voice is soft and innocent, but your heart is pounding as hard as your clit. Please, touch me. Fuck me right here. I’ve been such a good girl for you, Daddy. The words echo loudly in your head.
His eyes meet yours before slowly drifting down, scanning you from head to toe. "I’ve noticed how much you’ve improved this semester, so I was wondering if you’d be willing to help one of the students who’s struggling. Sharing notes or a few short tutoring sessions would help a lot."
The disappointment hits you like a punch. You’re standing here dressed for him, dripping wet and trembling with need, and he’s asking you for academic favors. No locked door. No biceps wrapped around your throat while he fucks you hard. Just tutoring another student. "Of course, Professor Park. I’d be happy to help."
He gives a small nod. "Thank you. I’ll email you the details. Keep up the excellent work."
You linger for a few more seconds, hoping he’ll say something else, but he simply turns his attention back to the papers on his desk — clearly dismissing you.
While waiting for the email he mentioned, you write in your diary:
"He asked me to stay after class and I swore this was finally going to happen — that he was going to fuck me mercilessly on his desk, choking me between his biceps and calling me his good little girl, his desperate pet. But nothing happened and fuck, it’s driving me insane. I’m dressing like a slut for him and he still stays so cold and professional. Luckily, I don’t give up easily."
────────
You arrive early and take your usual seat in the front row. As soon as the lecture begins, you pull a cherry lollipop from your bag, unwrap it slowly, and bring it to your mouth. At first it looks innocent — but you make sure it’s anything but.
You suck on it gently at first, your tongue swirling around the shiny red head, then take it deeper, hollowing your cheeks slightly. Your eyes stay locked on him the entire time — watching the way his muscular arms move as he explains the material, the serious tone of his voice, and the way his thick eyebrows furrow in concentration.
Every time he turns toward your direction, you push the lollipop in and out between your lips in slow, suggestive movements, imagining it’s his cock instead. He pauses mid-sentence for half a second as his gaze fixes on your mouth, then smiles — flashing those sharp canines. Holy fuck. Your pussy throbs at the sight.
Feeling bold, you don’t stop. You lick the lollipop from base to tip with long, wet strokes of your tongue. Every time his eyes meet yours, you suck it deep while keeping eye contact.
When the lecture ends and most students leave, he looks straight at you while you’re still sucking on the lollipop and packing your things. "Miss, a word, please."
You stand up quickly and walk over to him, pulling the lollipop out slowly with a wet pop as you reach his desk. Your lips are glossy and shiny as you smile sweetly. "Yes, Professor?" You slip the lollipop back into your mouth while you wait for him to speak.
This time he doesn’t even try to hide it. His gaze drops to your glistening lips, then to your breasts — your hard nipples clearly visible through the thin tank top, no bra as usual. "Your latest essay was…" His eyes finally return to yours, a small mischievous smile playing on his lips. "Incredible."
"Thank you, Professor," you reply softly, matching his mischievous smile. "I’ve been working really hard to be your best student."
He nods. "Good. Keep it up and you’ll certainly become my favorite."
You give the lollipop one final slow lick while looking him straight in the eyes, then turn to leave, swaying your hips in those tiny shorts. You can feel his gaze burning into you the entire way out.
That night, you write in your diary:
"Fuck, the way he stared at my mouth while I was sucking that lollipop… I bet he was imagining how my lips would look wrapped around his cock. I wanted him to grab my hair and shove himself down my throat right there in front of everyone. Daddy looked so tense today, but he still praised my academic effort again. I feel like I’m getting so close to finally making him snap."
────────
The class starts as usual, with you sitting in the front row, paying close attention to Professor Park’s lecture as he discusses the topics in that controlled, precise tone.
In the middle of the lecture, Ni-ki — the guy you’ve been tutoring — leans over from the seat next to you and whispers in your ear, "Hey, are we meeting again today?"
You smile at him and nod, leaning in closer on purpose because you know Professor Park is watching. "Yeah, already missing me, Nishimura?"
Ni-ki stays close, chatting quietly with you while the class continues. You smile widely and laugh at everything he says — he’s so funny and goofy. "We can review that part after class if you want," you say sweetly, loud enough for Professor Park to hear.
Sunghoon’s reaction is subtle but noticeable. His jaw clenches, one thick eyebrow lifting for half a second as he watches the two of you. He pauses mid-sentence when he catches Ni-ki staring at your breasts, then continues with a noticeably deeper, colder voice. When his eyes meet yours again, there’s something different in them. Jealousy.
"Concentrate, please," he says to the entire class, but his gaze is locked directly on you.
After class, when most students have left, you stay behind, pretending to organize your notes. Professor Park walks over to your seat and stops right beside you, towering over you with his arms crossed over his chest. His biceps strain against the sleeves of his shirt.
"Miss… I appreciate you helping Ni-ki, but I’d prefer if tutoring sessions stayed professional and outside of my lecture time."
You look up at him with feigned innocence, biting your lower lip. "I’m sorry, Professor. I was just trying to help like you asked… I really want to be useful to you."
Those words make his cock twitch inside his pants.
"That’s fine, as long as it doesn’t interfere with your performance," he replies. "You’re one of my best students. I’d hate to see that change." He lingers for a second longer, staring at you, before stepping back.
"One of." That’s not enough. You want to be his favorite. The only one.
That day, you write:
"He was jealous today, it was so obvious. Daddy didn’t like me giving attention to another guy and fuck, that’s so hot — it left me soaked. I wanted him to snap right there, drag me to his office, put me on all fours and fuck me stupid. I need him to claim me, ruin me, remind me who I belong to. Please, Professor Park."
────────
Another class ends. This time, you don’t wait for everyone to leave so you can have a brief moment alone with Professor Park. In a rush to meet your friends at a nearby café, you end up forgetting your notebook on the desk — the one filled with all your filthy thoughts about him.
Professor Park is packing up his things when he notices the forgotten notebook on the seat where you sat during class. He picks it up, planning to return it to you next lecture, but decides to open it first to check for a name — just to make sure it’s yours. His eyes scan the first page, then the next, and the next.
"Today I met Professor Park and my God, he’s so attractive…"
"I want him to bend me over the desk after everyone leaves, lift my skirt, and fuck me hard."
"I want to be Daddy’s favorite. I’d let him fuck my ass if that’s what it takes to be his good girl."
"I wanted him to grab my hair and shove himself down my throat right there in front of everyone."
He freezes, jaw clenched tight, every muscle in his body tense as he keeps reading. Page after page of your explicit fantasies — the way you teased him with the lollipop, dropped to your knees in front of him, wore shorter and shorter skirts with tighter blouses, all of it deliberately done to provoke him.
With every new entry, his cock grows harder, throbbing painfully against the confines of his pants.
You only realize you forgot the notebook when you’re already halfway across campus. Panic floods through you instantly — every filthy thought, every "Daddy," every explicit fantasy is written in there. Your stomach twists at the thought of someone finding it and reading everything. You run back to the lecture hall as fast as you can.
When you arrive, the door is slightly ajar. Peeking inside, you see that Professor Park is still there.
Breathless, you push the door open. His eyes lock onto yours the second you step inside. The air feels thick, heavier than ever. His gaze is different now — darker, more intense, hungry. In that same instant, you know you’re fucked.
"You forgot this," he says in a low, serious voice. A cruel smile plays on his lips as he holds the notebook out toward you, but he doesn’t let go when you try to take it.
"Interesting reading…" He flips through the pages again and reads one of the entries out loud. "Please, Daddy… notice how desperate your good girl is." Then he lets out a low, mocking laugh — clearly amused by how desperate you sounded in those notes.
Your face burns with shame. The words get stuck in your throat. What excuse could you possibly give when everything is written so explicitly? "Professor… I—"
He closes the notebook with a sharp snap and pins you with a piercing stare that makes your entire body shiver. "We’ll discuss this later. In private."
He finally releases the notebook. The moment it’s in your hands, you turn and flee as fast as your trembling legs can carry you.
The rest of the day is pure torture. You can barely sleep that night, your mind racing with every possible consequence — and every possible thing he might do to you.
Later that evening, your phone vibrates with an email from him.
My office. Thursday, 4:30 PM. We need to discuss the contents of your notebook.
— Sunghoon Park.
On Thursday, you spend the entire day getting ready. You wear the tightest tank top you own — thin enough that your hard, needy nipples are clearly visible — paired with the shortest skirt you’ve ever worn, one that barely covers the curve of your ass.
At exactly 4:30 PM, you knock on his office door, your heart pounding so hard you feel dizzy.
"Come in," he says from inside.
You open the door slowly. There he is, leaning against his desk with his arms crossed over his broad chest, jaw clenched, a malicious smile on his lips and a hungry look in his eyes as they rake over your body from head to toe. The cold, professional mask he always wore in class is gone, replaced by something much darker.
"Lock the door and sit down," he orders, leaving no room for argument.
You obey with trembling hands, locking the door before sitting down, pressing your thighs together. You can already feel your panties getting wet. For a few long seconds, he just stares at you, his gaze lingering on your hard nipples straining against the thin fabric.
When his eyes finally meet yours, he speaks. "You wrote about wanting me to bend you over this desk. About my arms suffocating you. About calling me Daddy. About dressing like a desperate little slut just to get my attention."
You feel exposed, vulnerable, and shamefully aroused, your pussy throbbing.
"I didn’t… I mean, I—" The words die in your throat as he steps closer, towering over you.
"Do you have any idea how difficult it’s been to stay professional?" he growls. "Watching you in class every day in those tiny skirts and tight tops. Reading how badly you want me to claim you."
Before you can respond, he grabs your waist and lifts you effortlessly onto his desk. His hands grip your thighs, spreading them so he can step between them.
"Professor Park…" you whimper, your voice trembling with need and nervousness.
He kneels in front of you, eyes locked on yours as he pushes your skirt up and pulls your panties to the side, exposing your needy, dripping wet pussy. The first touch of his hot tongue against your folds makes you gasp sharply.
"Oh God—" you moan, gripping the edge of the desk.
Sunghoon eats you out like a starving man — with long, slow licks from your entrance to your clit, then sucking hard on the swollen bundle of nerves. Two long fingers slide deep inside you, curling perfectly to stroke that sensitive spot while his tongue works relentlessly.
"Sunghoon, fuck— that feels so good," you whimper, tangling your fingers in his hair. "I’ve waited so long for this…"
He growls against your pussy when he hears you moan his name so casually. The vibration sends shivers through your entire body. His fingers pump faster and deeper as he sucks your clit into his mouth. The pressure builds quickly until you cum hard, thighs trembling around his head, loud moans ripping from your throat as you soak his chin and the desk beneath you.
When he finally stands up, his lips are glistening with your juices. He’s breathing heavily, the massive bulge in his pants straining painfully against the fabric.
"Please, Daddy…" You spread your legs even wider, eyes glassy with tears of frustration and pleasure. "I need your cock. Please, fuck me."
Sunghoon steps forward, pressing his clothed erection firmly against your soaked entrance and rubbing slowly. You moan softly, rolling your hips against him desperately, chasing more friction, but he pulls away again.
"I’m not reckless enough to fuck you in my office," he groans, clearly fighting for control. "No matter how badly I want to bury myself inside this needy little pussy."
You let out a pathetic whine, eyes pleading. He leans in close, gripping your jaw firmly with one hand.
"Tonight. My apartment. 8 PM. If you want me to fuck you properly." He pauses, his voice low and dark. "I’ll send you an email with the address."
────────
You arrive at his building exactly at 8 PM, wearing the sluttiest outfit you own. Your pussy is already dripping down your thighs by the time you knock on the door.
Sunghoon opens the door dressed differently from usual — a simple black shirt and gray sweatpants that do nothing to hide the thick, heavy outline of his hard cock.
"Come in," He orders and you obey, the door closing behind you with a heavy click.
The second you step inside, his reserved professor mask finally shatters and he snaps.
He grabs you by the waist and slams you against the wall, his grip so strong it will definitely leave bruises. "You have no fucking idea what you’ve done to me," he growls, pressing his erection hard against your stomach. "Reading page after page of you begging to be my little whore. Calling me Daddy while thinking about my cock."
You moan, arching into him desperately. "Please… I need it. I’ve needed your cock for so long."
He spins you around and bends you roughly over the back of the couch. Your tiny skirt rides up, exposing your bare, dripping pussy — you didn’t even bother wearing panties. His large hand comes down hard on your ass, making you cry out.
"Look at this desperate little cunt," he says, stroking the spot he just spanked. "Dripping all over my floor." Two thick fingers slide through your folds and push deep inside you without warning. You scream, pushing back against his hand as he fingers you hard, curling his fingers against that sweet spot while his thumb circles your swollen clit.
"You’re tighter than I imagined," he groans, pumping faster. "All those weeks teasing me in those tiny skirts and tight tops… you’re going to take every inch of Daddy’s cock tonight."
You’re already a sobbing, dripping mess. "Yes, Daddy, please fuck me."
He pulls his fingers out, yanks your top up to free your breasts, and spins you around to face him. Before you can say anything, his mouth crashes against yours in a hungry, demanding, almost desperate kiss — his tongue pushing past your lips to claim you completely.
You melt into him, moaning into his mouth while grinding against his hard cock. When he finally pulls back, your lips are swollen and you’re panting.
He walks you backward toward the bedroom, still kissing you between steps, until the back of your knees hit the bed. Sunghoon throws you onto your back, pulls off his shirt, and shoves down his sweatpants — finally freeing his cock that springs out, thick and rock hard with pulsing veins along the shaft. Your mouth waters at the sight.
He climbs on top of you, grabs your thighs and spreads them wide. Without any ceremony, he lines up and thrusts deep inside you in one brutal stroke, burying himself to the hilt in your soaked pussy. "Fuck, you’re so goddamn tight."
Then he starts fucking you hard — deep, merciless thrusts that make the bed creak and his heavy balls slap against your ass with every stroke.
You’re completely lost in it, moaning like a whore because he’s so big and the stretch is overwhelming. "Your cock is so big… you’re stretching me so good."
He leans down and kisses you again, swallowing your moans as he pounds into you. His muscular body pins you to the mattress, his heat and weight dominating you the best way possible.
"You’re mine now," he growls against your lips. "My perfect little pet. This pussy belongs to me now."
Sunghoon presses one hand firmly on your lower belly and starts fucking you with slow but incredibly deep strokes. His cock is so long and buried so deep that you can clearly see the bulge moving under your skin with every thrust.
"I can literally see my cock bulging your tiny stomach. Feel that?" He thrusts harder, pressing down so you can feel the head of his cock pushing against his hand through your body.
You nod, sobbing with pleasure, tears streaming down your cheeks. "Yes, I feel it. You’re ruining my pussy, Daddy. I’m so full."
"My cock is bigger than your little womb can handle… but you’re still taking every inch like a good girl," he groans, almost hypnotized.
"Please, don’t stop," you beg desperately, voice breaking. He fucks you even deeper, one hand still pressing on the bulge in your stomach while the other pins your wrists above your head.
The pressure becomes unbearable until you can’t hold back anymore. You cum hard, screaming as your pussy clenches violently around his cock, squirting while he keeps fucking you through it. The sight and feeling push him over the edge too. He buries himself as deep as your body allows and fills you with thick, hot ropes of cum, groaning loudly as he empties himself inside you.
He slowly pulls out of you, his cock glistening with the mixture of both your cum. You’re panting, legs still trembling from the intense orgasm, when suddenly he flips you onto your stomach without warning. He grabs your hips and pulls your ass up, putting you on all fours.
"Arch your back," he orders. "I want to fuck you like the desperate little pet you are."
You obey immediately, arching your back deeply and presenting your wet, swollen pussy to him. This position leaves you completely at his mercy as his tall, muscular frame towers behind you.
He leans over you, one hand sliding down your spine until he grabs the back of your neck, pulling you up so your back is pressed against his chest. With the other hand, he turns your head to the side and kisses you deeply. His tongue invades your mouth, claiming every inch while his thick cock teases between your ass cheeks.
You moan into the kiss, melting under him. "Daddy… fuck me harder," you beg breathlessly against his lips.
He kisses you even more aggressively, biting your lower lip before pulling back just enough to look into your eyes. "Open your mouth."
You obey without hesitation, sliding your tongue out slightly. Sunghoon leans over you and spits directly into your open mouth — a thick string of saliva landing on your tongue.
You moan pathetically and swallow it all. "Thank you, Daddy…"
"Good girl," he praises with a wide smile, then spits into your mouth again. "Now take my cock."
He pushes you back down onto the mattress, grips your hips with both large hands, and thrusts into you with one brutal stroke. The new angle lets him bury every thick inch even deeper, stretching your tight pussy to its limit.
"Fuck!" you cry out, fingers gripping the sheets. "You’re so deep like this… Oh my God."
Sunghoon starts fucking you hard, his hips slamming against your ass with loud, wet slaps that push your body forward with every thrust. His thick cock rubs against your cervix and every sensitive spot inside you — the obscene sound of your soaked pussy getting fucked filling the room.
He keeps one hand on the back of your neck, pressing your face into the mattress while the other spanks your ass hard in time with his thrusts, leaving red marks on your skin. "Take it," he groans. "This is what you wanted, isn’t it? To be fucked like a bitch in heat by your professor."
"Yes, yes, Daddy." you moan loudly, pushing your hips back desperately to meet his rhythm. "Fuck me harder… I love being your little slut."
He leans over you again, chest pressed against your back, and continues pounding into you mercilessly. Every thrust makes your ass ripple and your tits bounce beneath you.
Sunghoon reaches around and grabs one of your breasts roughly, pinching your nipple without slowing his punishing pace — his heavy balls slapping against your clit with every stroke.
"You’re so fucking tight like this," he growls against your ear, biting your shoulder. "This tiny pussy was made for my cock."
You’re sobbing with pleasure, completely lost in how deep and hard his huge cock is fucking you. "I’m gonna cum. Sunghoon, please... can I cum?" you beg, voice breaking.
He slaps your ass hard again, making you squirm under him. "Cum on my cock like a good girl."
You scream into the mattress as your inner walls clench violently around him, the orgasm hitting you violently. He doesn’t slow down — he fucks you straight through it, chasing his own release.
Until he buries himself to the hilt and fills you with another huge load, pumping rope after thick rope of hot cum deep inside your pussy in heavy spasms.
You’re still trembling and leaking his cum when he pulls out and suddenly flips you onto your back so he can look at your ruined body and flushed, wrecked expression. "On your knees," he commands, his voice low and rough.
You obey instantly, like you always do. Sunghoon reaches over to the nightstand where he keeps his satin ties and grabs a couple. "Hands behind your back, pet." He ties your wrists securely behind you and then binds your ankles, leaving you completely helpless on the bed.
The silk bites into your skin just tight enough to make you fully at his mercy. When you test the restraints and realize you can’t escape, a needy moan escapes you.
"Look at you…" he says, slowly stroking his cock, which is already rock hard again. "All tied up and dripping for me. Exactly how a desperate little slut should be.:
You whimper, your pussy clenching around nothing. "Daddy, please..."
He lets out a cruel laugh, then grabs you by the hair and drags you off the bed to the large full-length mirror on the bedroom wall. He positions you on your knees right in front of it, facing your own reflection. "Eyes open," he whispers into your ear. "Watch what I do to you."
You stare at the obscene image in the mirror: your wrists and ankles bound, your skirt bunched uselessly around your waist, tits exposed, and your face flushed with lust.
Sunghoon kneels behind you, his muscular body making yours look tiny. He yanks your head back by the hair and thrusts into you with one brutal stroke, burying his cock to the hilt.
He starts fucking you hard, deep and punishing thrusts that jolt your bound body forward. His biceps flex as he grips your hips, pulling you back onto his cock with every stroke. The mirror shows everything — your tits bouncing, your face twisted in pleasure, and his body dominating you from behind.
"Fuck, look how well your tight little pussy takes me," he groans. One hand wraps around your throat while the other arm snakes around your upper body. He pulls you back against his chest, smothering you between those massive biceps while he keeps thrusting. Your vision starts to blur from the overwhelming pleasure as you gasp for air, forced to watch yourself being destroyed in the mirror.
Sunghoon unties your ankles and in one smooth motion stands up, lifting your body like you weigh nothing. He presses you against the mirror, your tits and cheek smashing against the cold glass as he enters you from behind again.
The mirror fogs up with your hot breath while he fucks you relentlessly. "You teased me for weeks," he growls in your ear, one hand still gripping your throat. "Now you get to watch yourself get fucked like the whore you are." His hips slam against your ass with loud, wet smacks, his cock driving incredibly deep in this standing position.
You cum hard, screaming as your pussy squirts around his cock and your legs shake violently, but he doesn’t stop. He pulls out, spins you around, and lifts you onto his cock, impaling you completely again. His strong arms do all the work, bouncing your bound body up and down on his thick shaft.
"Beg for it," he demands.
"Please, Daddy, cum inside me again," you sob desperately. "Fill your good girl up… I need it so bad."
He buries himself to the hilt one final time and floods your pussy with another massive load, pumping rope after thick rope of hot cum until it overflows around his cock and drips down your ass.
Still buried deep inside you, he carries you back to the bed and sits you up on the edge of it, standing in front of you. "Open that pretty mouth. Time to clean Daddy’s cock and get your throat fucked."
He doesn’t wait for you to do it. He simply grabs your hair and slaps his cum-covered cock against your tongue a few times before shoving it straight down your throat. You gag hard, your eyes watering instantly as he forces his thick length past your gag reflex.
"That’s it, swallow it all, you filthy little cocksucker," he groans, starting to thrust deep and steady.
You gag and drool uncontrollably, thick strings of saliva running down your chin and dripping onto your tits and thighs. Glk- glk- glk. The obscene sounds fill the room as he fucks your face mercilessly.
You pull against the restraints around your wrists, trying to escape while moaning around his cock. When he pulls out briefly to let you breathe, you gasp desperately. "I’m your dirty little whore, Daddy."
He groans and thrusts back in, fucking your throat harder and faster while holding you in place. Tears stream down your face, but you keep looking up at him submissively. Finally, with a deep groan, he buries himself to the hilt and cums straight down your throat. You swallow every drop like the good girl you are, coughing and gasping for air when he finally pulls out.
Sunghoon releases the restraints from your wrists and sits on the edge of the bed, his cock still hard and glistening, slapping against his stomach. He pulls you onto his lap, gripping your hips possessively. "Get on top, baby," he says, his voice low and rough. "I want to watch you ride Daddy’s cock."
Even though you’re trembling and completely wrecked, you obey. You straddle him, align his cock with your soaked entrance, and sink down slowly, moaning loudly as he stretches you open again. "Fuck… Daddy, you’re so deep like this," you moan, bottoming out with a shaky breath.
Sunghoon leans back slightly, supporting himself on his hands, his thick dark eyebrows furrowed as he watches you. One large hand immediately slides up to your breast, squeezing it hard while his thumb brushes over your sensitive nipple. "Ride me. Show me how badly you wanted this."
You start moving, rolling your hips and bouncing on his cock. He slaps your ass hard. SMACK. the sharp sound echoing as your flesh jiggles. "Faster," he demands, slapping the other cheek even harder. "Don’t be shy. Fuck yourself on me like you wrote in that dirty little notebook."
You ride him harder, your tits bouncing wildly in front of his face. He leans forward and catches one nipple in his mouth, sucking hard while his other hand keeps spanking and groping your ass, occasionally spreading your cheeks so he can feel how tightly you’re stretched around him.
"Oh my God, Sunghoon!" you moan loudly, head falling back. "Your cock feels so good… I love your cock. Please, spank my ass harder!"
His big hand comes down again and again, turning your ass red while his other hand kneads and pinches your breasts, rolling your nipples between his fingers. The mix of pain and pleasure makes your pussy clench around him.
"Look at you… bouncing on your professor’s cock like a whore. These pretty tits are mine." He squeezes them together, burying his face between them, biting and sucking marks into your soft skin.
You’re losing control, riding him relentlessly while grinding your clit against his pelvis with every bounce. "I’m gonna cum, please. Can I cum?" you beg.
He slaps your ass one more time, hard enough to make you scream, then grips your hips tightly and starts thrusting up to meet you. "Cum," he growls against your chest. "Cream all over Daddy’s cock."
You scream loudly, your body shaking violently as your pussy clenches and squirts around his thick shaft. Sunghoon doesn’t stop — he keeps fucking you through your orgasm, spanking your ass and playing with your bouncing tits until he groans deeply and buries himself inside you, pumping another thick load into your already overflowing pussy.
Sunghoon gently rubs your wrists and ankles before lifting your trembling body along with his and carrying you in his arms to the bathroom.
Under the hot streams of water, he presses your body against the tiles, pinning you there. "Can you take one more? Just one more for me, hm? I know you can, baby…"
You nod quickly. "I can."
He lifts one of your legs, lines himself up, and slides back into your sore, dripping pussy. The water cascades over both of you as he fucks you deep and steady, one thick arm wrapped loosely around your throat from behind while his other hand gropes your breasts and rubs your clit.
"You’re such a messy little whore, but so good for me," he whispers in your ear, thrusting harder. "Still leaking my cum down your thighs."
"Yes, I’m yours," you whimper, pushing back against him. "Fill me again, please. Breed me. I want to be yours forever, Daddy."
He pins you harder against the wall until you cum again, moaning his name. With one final deep thrust, he groans and releases inside you once more, making the mixture of cum and water run down your legs.
Sunghoon turns off the water, dries you carefully, and kisses every mark he left on your body. He carries you back to the bed and pulls you into his arms, cuddling you against his chest.
"You were incredible tonight," he murmurs softly, stroking your hair. "Such a good girl for Daddy. You took everything so well."
You nuzzle into him, your voice low and exhausted. "Thank you, Daddy… I loved every second. I’m yours now."
He massages your sore wrists, thighs, and neck with gentle, careful hands, then brings you water and holds the glass while you drink. He cleans between your legs again with a warm cloth, kissing your forehead the whole time.
"Stay here with me," he whispers, wrapping you in those strong arms. "Rest, baby."
You fall asleep feeling safe and warm in his arms, completely owned, satisfied, and already dreaming about the next time.

You wake up slowly, your body sore and marked — your thighs sticky with dried cum, your throat still a little raw. You smile to yourself like a lovestruck idiot, then slip out of bed wearing one of his dress shirts that you stole from the chair in the room.
You walk toward the kitchen, following the smell of fresh coffee. He’s standing at the counter, so you quietly approach from behind and wrap your arms around his waist, pressing your cheek against his back.
"Good morning…" you murmur, kissing his back softly. "Thank you for last night. I can still feel you everywhere."
Sunghoon doesn’t turn around immediately. He stays still for a moment, then lets out a low, cold laugh that makes your stomach twist.
He finally turns, wearing that same reserved, stern expression he used during lectures as he looks at you like you’re something both pathetic and mildly amusing.
"You’re already acting clingy?" he says, his voice low and cruel. "One night of getting your holes ruined and you think you can play housewife?"
Your cheeks burn, but you still try to be sweet, pressing your body against his and rubbing your hard nipples against his chest.
"Sorry… I just feel so close to you right now," you whisper softly, looking up at him with big, adoring eyes. "I love being your good girl."
He reaches out and grabs your chin roughly, forcing your head back with a firm, almost painful grip. "Look at you," he says mockingly. "So desperate and sweet in the morning. You were screaming like a whore last night, begging Daddy to fill your insides with cum… and now you’re cuddling up to me like a lost puppy?"
Before you can respond, he releases your chin and turns back to the counter as if you don’t even deserve his attention. But you keep trying, stepping forward again and wrapping your arms around him from behind. "Please, Sunghoon… I really like you. It’s not just the sex—"
"Enough," he interrupts sharply. He turns again, grabs you by the waist, and easily lifts you onto the kitchen counter, spreading your legs. The shirt rides up, exposing your bare, still-swollen pussy. "You’re not going to play sweet and domestic after writing page after page about wanting to be my personal cum dump."
"But… I want to make you happy," you say softly, your voice trembling.
He leans in close, trapping you on the counter. "Then stay quiet and keep that little cunt ready for whenever I want it," he says coldly. "Sweetness doesn’t suit a desperate pet like you. Now spread your legs wider and stop pretending you’re anything more than my dirty little secret."
He delivers a hard, cruel slap directly to your clit, making you gasp. Then he steps back, leaving you sitting there exposed, dripping, and aching on the counter while he casually drinks his coffee.
