🕑 Added 2022-06-18 16:01:05 +0000 UTC“Your final exam grades are out - you all did really well! Thank you for making this such a great class, and I hope have a great break! If you see me around next semester, don't hesitate to say hi!" You cheerfully announce over the sound of the final bell of the college semester.
Many students cheer and wave as they leave, excited to finally be over with one more grueling period of their college years.
You sit down at your desk, similarly relieved that the days of grading papers and assignments were over for a while.
Too bad I still have research work over the summer, so I have to stay here. Hmm, maybe I'll find something interesting to do here in my free time.
You snap out of your thoughts as you see a girl approach you, clearly looking nervous.
"Hyoon? How can I help you?" You ask.
She doesn't give you her usual smile, and instead reveals a concerned disappointment.
"Sir, um..." She looks around, eyeing the few stragglers left in the classroom. "Can we talk privately?" She asks.
"Of course! Follow me to my office," you say beckoning to the back door.
You walk down the hall to your personal office and invite her in. She nervously checks the door to ensure it was closed.
"So..." You say as you sit down behind your desk and beckon her to take a seat opposite you. "What's the matter?"
"Well, you see, sir... the final grades came out... and... I'm... surprised," she slowly lets out.
You nod, having expected this conversation to happen. “Hyoon, I know it might be a bit of a shock to you. It was to me, too, since I know you're the top student in this class. I even made sure to go over your paper again - it's all graded correctly.”
She grimaces as her hopes get quickly shot down.
"But, I... my grade fell so far...! Is there any way I can make up for it?" She begs, clutching her hands to her chest.
"Hyoon... I'm sorry, but that's not how things work. Maybe if you were on the border of an A, I would consider it, but you're ending quite a few points below that," you recall, making her wince once more.
"…please, sir... i swear i'll do anything you want... i'll stay over the summer and help you with anything... i'll be your research assistant if you want..." She quietly mutters as she turns her head down, as if afraid of someone else hearing her.
Was her top shirt button always unbuttoned? It must have been like that before... right?
"Hyoon... what's so bad about one B?"
"I... I'm a perfect student. This isn't supposed to happen. If I get this B, I won't be on track to be the valedictorian anymore..."
Wow. She certainly has high aspirations. And I-
Your train of thought is cut off as she leans down, revealing her healthy cleavage through her partially unbuttoned shirt.
You shift in your chair as you drag your eyes away, but she remains in that position as she lowers her chin to rest on her hands.
"Sir, please... I'll do anything..." Her voice takes on a different tone, and your body starts to react. You shift again in your seat, but the stiffness in your pants remains uncomfortable.
"Hyoon... I think you should go. I..." Your mouth slowly hangs agape as her hands reach for her buttons and undoes one more, revealing a sliver more of her incredible package.
"Hyoon?"
"Yes?" She innocently replies.
"What are you doing?"
"It's just a little hot in here, isn't it?" She says, leaning over and pushing her breasts together.
"Uh... no, it feels just fine to me... Maybe even a little cold, actually..." You let out, getting the feeling that she wasn't listening to your words anymore.
"Hmm, maybe it's just me..." She says, biting her lip and staring up at you with piercingly sultry eyes.
She begins to undo the remaining buttons one by one, and you find it harder to look away. Her gorgeous, perky breasts start to become fully visible behind her translucent black bra, and she finishes unbuttoning, but keeps the shirt on.
"But if you're feeling cold, sir…” She slowly says.
She slowly starts to get on her knees, and she disappears underneath your desk until you feel her hand pressing up against your boner. "Maybe I could warm you up..."
"Hyoon... you could get expelled if you do this..." You warn her.
"Shhh... that'll only happen if you report me. And you won't... because I know you want this. You've wanted me the whole semester...." She says, her tone completely changing as she starts to eye your growing bulge.
Fuck... she's right. She's the hottest student I've ever laid eyes on... and she knows it.
You see her face beneath you, and you stifle a groan as her hands unzip your pants. You lift your hips up to let her strip you, and she gasps in admiration at your size.
"You've probably never done th-HMPH!" You bite back a moan as she dives onto your cock, smoothly taking in half of it as she settles down between your legs.
As she quickly uses her wet, warm mouth to smoothly slide up and down on you, you know it’s so wrong to be enjoying it this much, but it feels so right.
You squeeze the arms of your chair as she tucks back a strand of her hair and continues sucking, keeping eye contact with you as she sloppily begins slurping you down.
You stare in amazement at her ability as you feel her throat widen and allow you access to her wet heat.
Her sharp gaze turns you on even more, and you grab the back of her head and push her further onto you. She almost gags, but keeps going as she lets you drive yourself up into her mouth.
"Fuck... keep going, just like that..." You encourage her. "You gorgeous fucking slut... keep sucking..."
Her hands grip your thighs to try to brace herself, but you only increase the pace, already practically face-fucking her as she tries to bare it all.
"Look at how practiced you are... you've probably sucked off quite a few guys to get all your perfect grades, right?" You remark.
She hums and nods, making it perfectly clear that she had done so and had no qualms about it.
"No wonder you wore all those short skirts and low-cut tops to class... you wanted this. You're a filthy slut, you know that?" You say as she uses her hands in tandem with her tongue. Her lips start to turn redder, and you can feel her tongue gently pressuring your tip.
"Fuck, you're good..."
Three knocks sound at the door, and you snap up in surprise, barely composing yourself as another figure gently starts to open the door.
"Oh! Come in! But, um... stay right there!" You say, trying not to sound suspicious. The student enters, and while your hands remain above your desk, Hyoon unbuckles her bra and moves your cock from her mouth to between her breasts. You nearly go delirious from pleasure as you feel the warm, pillowy flesh surround your member as she begins pumping you, all while luckily hidden underneath your desk.
"Tina!" You exclaim, trying to keep your voice cool.
"Hi..." She responds, staying at the entrance, as per your request. "I wanted to talk to you... about my grade..."
"Oh! What... about them?"
"Well, I... I was going to pass your class... but the final pushed me below the passing grade, so I'll have to retake the class..." She grumbles out, seeming disappointed.
"Ah... I'm… ~oh, fuck~ sorry, Tina,” you blurt out as Hyoon begins gently kissing the tip of your shaft every time she pumps it up between her luscious mounds.
”Wait, what did you say?” She asks, confused.
“Um… I said I’m sorry about that, Tina…”
"Well... Is there anything I can do?" She asks hopefully.
Hyoon's titjob was making your hormones flare, and your eyes scan over Tina's fresh, petite body, wondering how she would feel bent over your desk, moaning as you fuck her raw from behind and-
"Sir? Are you ok? You look... red..." Tina says.
"Oh, yes, I'm fine. Um...Tina...?"
"Yes?"
"Why don't come over to this side of my desk?" You ask.
Hyoon's eyes widen as she hears your words, but you place one hand on the back of her head and pull her in, sheathing your cock inside her mouth.
"WHAT THE FUCK!?!" Tina yelps as she sees what was occurring underneath your desk, and she quickly backs away.
"Shh..." You quietly say, beckoning her forward. "Don't worry, she's here for the same reason you are..."
"Wha-!" Tina blinks, unsure how to process what she was seeing. "Sir! That's... you can't do this!"
"Oh, I'm not doing anything! I'm just helping her raise her grade..." You say, smiling. "And I could do the same for you, Tina..."
"But... Hyoon! You already have such a... high grade, don't you?" Tina asks, now paying attention to the girl on her knees.
"Well, it wasn't enough for a perfect girl like her..." You answer for her, running your fingers through her hair as she continues sucking you, now accepting her fate. "Perfect body, perfect face... all that's left are for her to earn her perfect grades."
"Bu-! Wha-!" Tina cries, still in shock at the sight.
"Tina..." You slowly call.
She refocuses as she hears her name, and she looks toward you.
"Come here..." You softly demand, stretching out your hand.
She hesitates as she sees where your eyes were gazing, but she slowly approaches, and she bites her lip as your hand reaches her jean shorts and unbuttons them.
You pull her zipper down, and her cheeks start to flush as her gaze fixates on the sight of Hyoon deepthroating and blowing you from below.
You reach your hand in, and meet her clit through her underwear, making her grasp onto your arm for support as she gasps in surprise.
"~OH~ ...oh my god..." She groans out, nearly bucking your hips as her body craves more.
"Hyoon, come up from there. You know what I want," you say, redirecting your attention.
You scoot your chair back, and the girl stands up, wiping a strand of saliva from her mouth and fixing her disheveled hair.
"Of course... Sir."
She quickly pulls down her skin-tight leggings and underwear, revealing a perfectly shaped slit that was already moist.
"Look how wet you are..." You smirk as she straddles you in your chair. "Who would've thought? Such a dirty girl... living inside that stunning body..."
Her thick thighs slowly settle down on either side of you, and you forcefully grasp them, reveling in the feeling of her smooth skin and immaculate curves, which you had only ever been able to watch from a distance.
But the true pleasure comes as she sits down on your cock, letting you feel her tight insides. She groans as you stretch her out, and places her hands around your neck before beginning to ride you. The gorgeous flesh of her ass starts to bounce against your hips with each thrust, and as your fingers reach into Tina's panties and start pushing inside her, both girls were now struggling to stifle their delight.
You wind your hand back and give Hyoon a sharp slap on her right ass cheek, watching as it hypnotically jiggled back and forth.
"Faster." You smack her on the other side, admiring how red the flesh became.
She bites her lip from the pain and increases her pace, now lifting her hips almost completely off of your cock before slamming them back down, giving you a whirlwind of pleasure as every inch of you disappears into her wet folds.
"Mmm, keep riding me, you horny fucking whore..."
"Oh, yes... fuck me... please... with your… FUCKING COCK! GOD, FUCK!" She pleads, finally giving in to the pleasure and blurting out the thoughts running through her mind.
Tina's thighs were starting to shake from your finger-fucking, and she sits down on your desk, fully removing her shorts and spreading her legs to give you better access. You push your finger even deeper, and gently curl them inside her, making her squeal and clutch the desk beneath her.
Hyoon's nails dig into your back as she starts to go even faster, and her breasts bounce erratically before you take one into your hand. You gently twist her nipple, making her cry out into your neck.
You continue rapidly pumping Tina's tight walls while Hyoon's eyes roll back in her head from the pleasure of your shaft bottoming out inside her.
She yells out obscenities and begs you for more, and you oblige, slamming her hips down onto you as you begin to feel your loins coiling tightly.
"Yes... take my cum, you slutty bitch..."
And in a rapid few seconds, you grab Hyoon's body and ravage it as forcefully as you can, pounding her insides as deeply as possible and taking every inch of her for your own pleasure before finally erupting inside her, giving her no warning before you climax deep within her.
She releases her loudest shriek yet as she cums, feeling your warmth penetrate her and your shaft pulsing inside her.
She collapses on you for a few more seconds, panting and feeling your seed pool within her.
Her hot breath blows onto your neck as she rests, before you gently pull her off and get her to stand up. Her body was now a leaking mess of unkempt hair, blurred makeup, reddened flesh, and a filled pussy, but she smiled nevertheless, content that she had gotten what she wanted.
Tina sighs in disappointment as you pull your fingers out of her, biting her lip in sexual frustration as she had gotten quite close to a release.
"Hyoon..." You finally pant out.
"Yes, sir?"
"Congrats..."
"Thank you for the A, Mr.-"
"The A?" You interject.
"...yes? The A? That was the deal, right?"
"I don't recall ever making a deal like that..." You slowly say, shrugging.
Her eyes widen, and she speaks very carefully.
"But you are... going to raise my grade... right?"
"...Eh, sure. By 1 point."
"1 point!"
"Yup. If you want more than that... I guess you'll have to come see me again soon...."
"But... it's summer break! I have to go home!"
"No, you don't. You offered to be my research assistant, didn't you? So... now you are. Except, you'll be assisting me in a different way..." You smile, already imagining all the fun you would have with her.
She gasps at the proposition.
"Sir! I..." Her voice trails off as she sees the resolute look on your face.
She reluctantly nods, knowing there was no other way out.
"Fine..." She groans, before standing up and pulling on her pants.
"Goodbye for now, my little assistant..." You wave as she fixes up her hair and storms out.
"Now, Tina..." You say.
"Sir, I'll be here over the summer..." She says, sounding more excited than you expected.
"Oh?"
"Yup. And I'll... be available... if you want to call me over... I can assist you too..." She mumbles out, blushing red.
"Tina...! I never knew you were like this..."
"Wha-! I'm... not like anything! I just... I want to pass this class, sir..."
"Hmm. Ok, fine. You can stay over too. But it's... only to pass the class, right? It's not because..." You gently start stroking your limp cock once more. "You want this... right?“
She conspicuously looks away and clears her throat.
"No, sir. I would never... never..."
You reach your hand toward her and pull your cheek toward you. Her skin tingles at your touch, and you surprise her by gently sticking your finger in her mouth.
She closes her lips around it and slowly sucks it, making you chuckle at her complete submissiveness.
"Oh, Tina... You innocent little harlot..."
You remove your finger, and she looks up at you once more.
"Alright, then. I guess I'll see you later... if I want to."
She nods and quickly rushes out, closing the door behind her.
You sigh, realizing for the first time what you had gotten yourself into.
Well, if I get fired for this, I might as well make the most of it...
