Chapter Text
Felix was the pinnacle of the “golden child”. Always kind, always caring, always an amazing student and son. Everyone loved him. He had that type of charm. However perfect he seemed, Felix was completely fucked. An angel with insatiable lust and need. And he was tangled up with his teacher, Professor Seo.
The much older mathematics teacher that Felix had been fantasising about since the beginning of highschool. He was the hot topic among Felix's entire grade, nearly half the girls had childish crushes over him which disgusted Felix. Professor Seo was worth so much more than some school girl crush. He was worth something more serious, more mature.
Felix spent all of his classes staring at Professor Seo with piercing eyes that caught the older man's attention many times. But Felix being a straight A student had no reason to be spending extra time with him. It never stopped him from walking up to Professor Seos desk and bending over to ask him questions or calling him over to his desk so he could take in the vision of his teacher leaning over him, leaving him in shadow. At this point he was talking up more of Professor Seos time than the kids that actually needed his help.
One day after class he called Felix before he left out the door. “Felix, could you stay behind for a second?” Felix’s face flushed as he tried to bury his growing smile. “Of course Professor.” Professor Seo gestured to the spot right in front of his desk and Felix sat down with his legs crossed, his pleated skirt slightly riding up.
“I’ve been noticing a strange pattern with your work in class lately Felix. Your tests are flawless but you keep asking me questions about the material and if you know the material well enough to get 100% on the test then there is no reason for you to be asking me for help.” He paused and looked down at Felix while he leaned back in his chair. “So I think it’s valid for me to ask, are you cheating on your tests Felix?” Felix bit his lip, batting his eyelashes before answering.
“I’m sorry Mr. Seo. I’m not cheating on the tests, I understand the material perfectly.. I just can’t help but want to talk to you.”, “Well that’s nice Felix, however I have other students that need my help so I have to spread my time evenly.”, “But I do need your help Mr. Seo…” he raised an eyebrow at Felix's remark. “How do you mean Felix?” Felix stood up and walked over to Professor Seo and leaned against his desk beside his chair. “I just can’t focus in class… I want you so badly” he Reached for Professor Seos tie and fiddled with the end of it between his fingers.
“F-Felix.. I appreciate your honesty but this is highly inappropriate.” he grabbed Felix's much smaller hand and pulled it away. “You’re my student. I’m your teacher. Any relationship between us should stick to those titles and despite that I’m much older than you, most likely older than your father.” Felix rolled his eyes and knelt down between Professor Seos trembling thighs.
He ran his slender hands up and down with heated intention. “I can keep a secret you know… and I’m very aware of how old you are, it’s kind of hot…”, “Felix!” Professor Seo demanded and grabbed his wrists, looking at him with stern eyes. “This is not appropriate. I need this to stop right now.”, “You need to but I bet you don’t want this to stop.” Professor Seos eyes widened. “I’m right aren’t I?”
The grip on his wrists loosened and this time Felix took a seat on Professor Seos lap, wrapping his arms around his neck. “I see how embarrassed you get when you catch me looking at you… you must know what I’m thinking.” He chuckled. And despite the apprehension Professor Seo talked with his hands were slowly snaking around the thin waist of the young boy on his lap.
“Do you think I’m pretty Mr. Seo?” he nearly choked on the harsh swallow at Felix’s question. “I.. I can’t answer that..”, “Of course you can.” Felix nuzzled his nose into Professor Seos neck, the hot breath sending chills up and down his back. “There’s nothing wrong with thinking I’m pretty.”, “There are plenty of reasons I shouldn’t be thinking that Felix.”, “But do you?” Silence fell across the room, squeezed out from the overwhelming tension.
“You know you haven't moved me off your lap yet…” Felix whispered. Professor Seos grip on Felix’s waist tightened. “Can I kiss you Mr. Seo?” He nodded slowly and Felix smiled in response as he leaned forward and placed a small kiss on the older man's lips, relishing in the further tightening on his waist. Professor Seo exhaled, letting out a small “fuck…”. “You seemed to enjoy that… what do you think Mr. Seo?”, “You’re so pretty…” Felix smiled and gave the man another small kiss. “Do you want me to stay longer..?”, “You shouldn’t…”, “Do you want me to stay?”, “Yes…”, “Take me to your office.”
They stood up and Professor Seo took his hand and led Felix to his office at the back of the room, locking the door once they were both inside. “Sit down.” he demanded, referring to the small couch beside the desk. Felix sat down, squeezing his thighs together while he licked his lips. “What do you want me to do Mr. Seo?” He double checked the door before looking back to Felix, the burning debate in his mind clearly reflected in his dark eyes. “What.. what would you do?”, “Anything for you…”,
“Then get on your knees.” The switch between the kind teacher he knew and this new dominating personality made Felix's head spin. He softly got onto his knees and looked up at his teacher through his eyelashes. Professor Seo walked towards him and cupped Felix’s chubby cheek, brushing his thumb along his beautiful freckles.
“God you’re gorgeous…”, “You think so?”, “Yes.. You look even better like this.” he pressed his thumb to Felix’s lips as his desires began to take over. “I think you’ve spent too much time talking.. Why don’t you use that mouth of yours for something else hm?” Felix nodded and began undoing Professor Seos dress pants. He took the throbbing member out, licking his lips while staring at it. He was so big, just like Felix thought.
In the back of Felix's mind he wondered if he’d be able to take the whole thing. Professor Seo interrupted his thinking, carding a big hand through Felix’s blonde hair to hold it out of his face. “Get to work.” Felix smiled and took the tip in his mouth, licking around the head. The man above him hissed through his teeth as Felix sunk down more and more.
“Have you done this before Felix..?” he popped off the man's cock for a second, still keeping the head near his lips. “A few times for some ex boyfriends..”, “How big were they?”, “No where close to you… you’re so big” Professor Seo smirked and signalled for Felix to continue. “You’re very good at this darling. I should keep you under my desk, make you suck me off during school hours so everyone can see what a slut you are.”
Felix moaned at the thought, he had fantasised about it so many times. Getting up during class to go down on his professor so all the pathetic girls who had a crush on Professor Seo knew he was the only one that could have him. He went down further until the man held him down as he came down his throat.
“Fuck.. you’re so good at that.” Felix opened his mouth to display the cum on his tongue before he swallowed as Professor Seo smiled at him. “You won’t tell anyone about this right darling?”, “Yes… I won’t tell anyone.” Professor Seo sat down at his desk and pulled Felix onto his lap. “So you’ll be my little secret?” Felix moaned in response. “Want that so badly… wanna be Mr. Seos' little pet.”
he smirked at that answer and kissed Felix one more time, still tasting the slightly bitter taste from the younger's lips. “As much as I’d love to keep you here it’s late, both of us need to go home.”, “You’re going to go back to your family? Are you going to let your wife touch you…? I’d be so much better than her you know.” Professor Seo chuckled as he lightly pinched Felix's cheeks as he frowned.
“Don’t frown darling. No, I won't be doing anything with her tonight, not when all I could do now is think about you.”, “Was I better than your wife Mr. Seo?”, “Yes you were.. You were so good for me.” Felix preened at the compliment. “When can I come see you again?”, “How about you stay after class at the end of the week? Maybe we can do a bit more then.” Felix smiled and kissed him on the cheek before getting off his lap, grabbing his stuff and leaving his office. “I’ll see you then Mr. Seo.” he winked and left.
When he got home his dad was in the kitchen cooking dinner. “Are you home Felix?”, “yes dad!”, “What took you so long? I’m almost done dinner I thought you were gonna miss it.”, “Sorry daddy Jisungie needed help with some work.” he walked into the kitchen and sat down at the table right as Chan brought in dinner, setting it infront of Felix and kissing him on the top of his head. “You’re such a sweetheart huh? Always helping everyone.”,
“Learned it from you daddy.” Felix smiled. They ate dinner in peace and then Felix went up to his room, flopping onto his bed. He undressed into his underwear and wiggled under the blankets and pulled out his phone. He scrolled through his school's social media account until he found a picture he was very familiar with. It was taken during track and field day,
Professor Seo was one of the teacher volunteers for the day and his look had all of his fangirls and Felix swooning. He was wearing a light grey tank top that showed off his strong arms and gave a small glance at his amazing chest muscles. It had been hot that day so his hair was a bit damp with sweat causing his curly hair to slightly straighten and stick to his forehead.
Felix could imagine he looked the same when the man came out of the shower with a small towel hanging low on his waist. He reached his hand between his legs, feeling himself while thinking about how Professor Seos cock felt in his mouth, he could imagine taking it in his pussy, letting his teacher fuck him so deep. It didn’t take long until Felix came, his head falling back onto his pillow with a loud sigh.
Felix spent the rest of the week waiting for his scheduled time with Professor Seo and to him it seemed like forever. Even if he wouldn’t be staying after class until the end of the week, that didn’t stop him from teasing his teacher every day.
Felix was partial to wearing skirts, it got him plenty of attention which he loved but overall they were just pretty and fun to wear. Professor Seo seemed to think they were pretty too. During class Felix would notice him staring, raking his eyes up and down longingly. Knowing this Felix always made a show when he wore a skirt in front of Professor Seo.
He’d constantly get up from his seat to walk around the room, giving Professor Seo a full view of his legs and the skirt that barely covered his ass. Or he’d drop his pen so he could bend over and show off his panties that peaked out from under the skirt. Professor Seo was so easy to read, he spent almost all class sitting at his desk instead of standing at the front of the class like he usually did. Anybody would wonder why he was doing this, if he was hiding something but Felix knew exactly why.
Finally it was the last day of class before the weekend and as everyone was leaving Felix was called into Professor Seos office. Felix said goodbye to his friends and skipped his way to the office. When he closed the door
Professor Seo was already sitting at his desk, this time Felix noticed the framed photo of Professor Seo, his wife and kids was put face down on the desk, the gesture made Felix proud. “What did you want to see me about Mr. Seo?” Felix joked. Mr. Seo signalled him to come around to the other side of the desk and Felix followed his instruction and took his place on the man's lap.
“You’ve been impossible the entire week you minx. Do you know all the trouble you put me through?”, “I just wanted to get your attention Mr. Seo..”, “Oh you definitely got my attention darling. But I’d prefer you didn’t do it in the middle of class.” His big hands found their way to Felix’s plump ass, reaching under the short skirt and squeezing it gently. Felix moaned and rested his head in the crook of Professor Seos neck.
“Are you going to punish me then Mr. Seo?”, “No dear. Maybe if you keep behaving like this but you didn’t know any better did you? You’re just so needy right?” Felix nodded and left a small kiss on the older man's neck. “I won’t punish you this time but if you keep misbehaving I’ll have to.” Felix started slowly grinding on his lap to get a small taste of friction until he was stopped and held down by Professor Seo. “What did I just say dear? You have to behave for me.”,
“Sorry… I’m just so horny Mr. Seo…”, “I know darling, I’ve kept you waiting so long you must be so needy right?”, “Yeah.. Please touch me already.” Felix let out a small gasp when he was picked up and brought over to the couch, now laying on his back while Professor Seo began to pull down his skirt. “Such pretty panties dear, I saw you trying to show them off to me earlier today. They’re cute but I’d prefer them off.” He pulled them the rest of the way down revealing Felix’s pussy that was already beginning to leak. “Well then… you didn’t tell me you had a pussy darling.” Felix hid his face behind his hands.
“Do you like it..?”, “Of course dear, it’s such a pretty little cunt.”, “It’s s-so empty… need you in me please..”, “Calm down–” he cooed. “I’ll make you full in just a minute.” He walked over to his desk to grab a condom out of the drawer. “You're gonna use a condom?”, “Of course I am Felix–” he ran his hands through his dark hair pushing it back and out of his face. “You do understand I can’t fuck you raw right dear? As much as I want to, if something happened it would be a big problem.”,
“I know…” Felix looked down and frowned. Professor Seo hooked a finger under his chin and lifted his head to meet his gaze. “Don’t be upset darling, maybe someday we can do it without a condom.”, “Really?”, “Sure.. and I’ll fill you up as many times as you want.” Felix smiled and kissed him on the cheek.
“Now can you hurry.. Want you inside.” Professor Seo chuckled. “I know.. Do you think you can take me right now or do I need to work you open?”, “N-no.. fingered myself in the bathroom before class.”, “Did you now?”, “d-didn’t want to wait..” The answer pleased his teacher and he pushed in nice and slow making Felix feel every inch.
Professor Seo was definitely the biggest Felix had ever had, it nearly broke him but it felt amazing. “Fuck… you’re so tight. I thought you weren’t a virgin.”, “m’ not… just wanted to be good for you…”, “Such a sweet little slut. Now relax and let me fuck you dear.”
The pace started off slow, Professor Seo moved with so much intention and passion and it made Felix feel so wanted. There were moments when his hips jerked telling Felix he desperately wanted to move faster. “Y-you can go faster.. I can take it.”, “Darling I’ve been waiting all week to fuck you, I’m going to take my time. Fuck you so much without letting you cum until you beg me to let you finish.”
Felix whimpered in response. Professor Seo could sense a bit of annoyance that he denied to go faster so to compromise when he pulled out he’d plunge back in hard and quick. Felix screamed at the pleasure. “Darling you’ll have to quiet down.”, “S-sorry.. Just feel so good~”, “I know dear but no one can catch us.” So he brought his hand up to Felix's mouth.
“Open.” Felix obeyed and took Professor Seos thumb into his mouth, sucking and licking around it. The screams of pleasure now quelled to softer moans. “Such a good slut, always listening to me. You act like such a brat until I start touching you.” He leaned forward and latched onto Felix’s collarbone and left soft kisses along his shoulders.
Felix was on the very edge of cumming, the multiple sensations and the thought that he was currently fucking his teacher that was twenty-seven years older than him was overstimulating. “Mr. S-Seo~ please let me cum! It’s too much I wanna cum.”, “You already want to cum darling? I’ve only just started.”, “I can c-cum again! I promise, please please please let me cum..”
This time Professor Seo took pity on Felix, going back to slow and intentful thrusts while continuing to lightly mark up his neck and rub his clit. “You’ll have to cum again if I let you this time alright?”, “Y-yes! Yes yes yes I’ll cum again, make me cum again please Mr. Seo…” The end of his sentence dragged out in to a long high pitched moan as he came around Mr. Seos cock.
The fucking didn’t stop, he kept thrusting Felix through even further overstimulation. He keened as his eyes rolled back and his hands gripped the arm of the couch. “You’re taking me so well darling, how’re you feeling?”, “S-so.. so good.. Mr. Seo feels so good in my pussy~”, “So cockdumb.. Want Mr. Seo to keep fucking you dear? Make you cum again?”,
“Pleassseee~ please Mr. Seo… Wan’ you to make me cum again.” He began picking up the pace in both his thrusts and the speed he rubbed Felix's worn out clit. Tears ran down Felix’s freckled cheeks leaving pale streaks among the red that spread across his face. “You look so beautiful right now. So pretty and fucked out if only you could see yourself.” Professor Seo looked on in amazement until he had an idea.
He pulled out his phone and took a video while he fucked into Felix, catching both the beautiful sight and all of Felix’s whiny moans. “Such a pretty slut. Tell Mr. Seo how you’re feeling darling~”, “S-so good~ you fuck me so so good, wan’ you to fuck me all the time.” Felix hiccuped through his sentence. “Yeah? You want me to fuck your pretty cunt more?”, “Never wan’ you to pull out, j-just stay in me until you ah~ fuck me again.”,
“That’s what you want dear? You’ll be so messy, your pussy is already so sloppy.”, “y-yes~ want Mr. Seo to make my pussy sloppy, I-I’m so fucking wet for you all the time.” The man above him started getting progressively louder, growling through his teeth. “Fuck.. I’m gonna cum darling, your pussy feels so good.”, “yes cum! Please cum Mr. Seo, wan’ all your cum in my pussy please~” he gave one last thrust as deep as he could and filled the condom to the brim just as Felix was cuming the second time, spasming around his cock as he felt the extra pressure.
They stilled as they rode out the intense pleasure. Breathing into each other as Professor Seo locked Felix in a heated makeout, eating all of the sweet moans that fell from his students lips. After a while he pulled out, tied the condom and threw it out.
He stopped the recording and put his phone back in his pocket. “Felix dear, are you with me?” Felix took a bit to gather his breath back and answer. “Y-yeah… so tired.”, “Just lay back and I’ll get you cleaned up ok?” Felix let out an exhale but suddenly gasped, slapping his hand to his mouth as Professor Seo dove down and licked up all of Felix’s wetness.
“Ah~ Mr. Seo… I’m so s-sensitive.”, “I know darling, just lay back and let me help.” Felix's moaning was nearly uncontrollable. The soft muscle against his overstimulated folds sending him into a type of overshock. “You taste as sweet as you look dear, God I’m so lucky to have you hm?” Professor Seo wiped the excess from the corners of his mouth and dried the rest of Felix off with a few tissues.
“Do you think you can stand Felix?”, “I-I can try..”, “Ok go slowly, I know I was a bit harsh earlier.” He helped Felix get dressed again, luckily any marks he might have left weren’t visible as long as Felix had his shirt on. “How do you get home Felix?”, “I usually walk home, my house isn’t that far away.”, “You’re still pretty weak, I’ll drive you home today ok?” heat rose to Felix's cheeks as he smiled. “Thank you Mr. Seo.”
They got into Professor Seos car, Felix curling up in the comfortable seat nearly half asleep and Mr. Seo pulling out of the driveway. Felix gave him directions and they headed out. “You know I had a really good time Mr. Seo..”, “Yeah? I’m glad darling, you were very good for me.”, “I wish I could see you more often… instead of just at school.”
The air turned thick with tension as Professor Seo pondered. “Trust me darling I would love to see you more, I’m just not sure how safe it would be…”, “I know.. And you’re wife and all that.” Felix stared out the window. His attention was brought back by Mr. Seos strong hand squeezing his thigh.
“Maybe when I have a day off I can take you somewhere. Maybe the next town over. How does that sound?” Felix bit his lip trying to conceal his bright smile. “You’d do that for me Mr. Seo?”, “I’d do a lot of things for you dear.” They sat through the rest of the drive in silence while Felix fixated on the older man's hand rubbing up and down his thigh. “I’ll have to drop you off a little bit away from your house just to be safe alright?”,
“That’s fine, I’m feeling a lot better now.” He stopped the car and unlocked the doors. “Are you sure you’ll be able to walk for the rest of the way?”, “I’m sure–” Felix leaned forward and gave Professor Seo one last deep kiss before he grabbed his bag and got out of the car. “Thank you for driving me home.”, “Anything for you darling.” They smiled at each other and then he drove off.
His dad was sitting in the living room when he got home. “Hey kiddo, I was wondering when you’d get home. Were you helping Jisung again?”, “Mhm, what’re you watching?”, “Just a movie, wanna come sit with me?”, “Of course daddy.” Felix took off his shoes and sat down cuddled up next to his father. “How was school?”, “So fun, class was really good today.”, “Well I’m glad my boy is doing so well.”
Chan smiled down at him and stroked his son's soft hair making Felix purr. Later that night Felix stayed up late silently touching himself thinking about his time with Professor Seo. And when he fell asleep he dreamt of the promise he made him. Being able to go out in public with him, showing everyone how much he loved him. He wanted it all so badly. Suddenly he was woken up by a buzz from his phone. A video sent from an unknown number. The message read:
Hey Darling, you looked so pretty today. Can’t wait to taste you again.
The video linked underneath had the thumbnail of Felix with his legs spread and Professor Seos thick cock deep inside of him. He ducked under his covers and watched the video on the lowest volume. Professor Seo was right, he did look pretty. He texted back:
Thank you so much Mr. Seo~ I’ll be thinking about you all night…
Then he changed the contact name to Mr. Seo🩷 before turning his phone off and going back to sleep.
