six months after yes, professor...

"C'mon baby, I'm hungry!"

You giggled, shaking your head at Hwang Hyunjin, your boyfriend of three months. He tended to be whiny and dramatic at times, especially when he got hangry. But since you'd been his friend since before you started dating, you'd known what to expect.

But today, you had a special plan. Because you weren't just hungry for pizza.

You and Hyunjin had started dating back in January, around three months after you'd officially met during your first semester of senior year. The two of you had really connected over your love for the arts, being two creative people suffering through their one and only math course of their college career. You'd truly come to care about him not only as a friend, but as a potential soulmate, too.

There was really nothing wrong with your relationship, and you had zero complaints about him as a partner. He was sweet and attentive, smart and thoughtful, and he always made time for you. He especially loved setting up cute dates, from painting classes to movie nights. He was also incredibly passionate, always wanting to be near you, whether it be just touching and cuddling, or full-blown makeouts. He constantly gave you butterflies, a warm feeling in your stomach. And it certainly didn't hurt that he was irresistibly sexy.

But there was one thing that had been weighing on your mind for the past month or so. Even though your relationship was strong, and the romantic and sexual chemistry was hot, sizzling even, you had always left each sexual encounter... wanting more.

Because no matter how hard Hyunjin tried, he just couldn't make you cum.

Of course, he was always very apologetic and embarrassed, which was incredibly endearing. And really, you didn't mind that you couldn't finish. He was totally okay with you touching yourself instead, especially if he got to watch. But c'mon, what girl didn't want to cum at the same time as their gorgeous art major boyfriend?

Because at the end of the day, you knew why you were struggling. Every time you came close, hanging on that precipice, begging your body to just release, like clockwork... a certain glasses-clad math professor in a sexy dark sweater would invade your mind. A professor who didn't even teach you anymore. But no matter how long it had been since you'd spoken to him, and no matter how hard you tried, you couldn't shake the thoughts.

But tonight, you were determined to break the cycle. Tonight, you were going to enact a plan: seduce Hyunjin, and have the best sex of your life.

"Okay, okay!" You decided to play along with your hungry boyfriend's complaints for now, following him into his apartment, and laughing all the way to the kitchen. "I wouldn't want my handsome man to starve, after a long day of studying."

He nodded furiously. "Yeah, since you forced me to work, I deserve food!"

You rolled your eyes, slapping his arm playfully. "So me wanting to help you pass English Lit is forceful, now? What about you making me study Art Comp — an elective, might I add — for three hours straight, huh?"

Smirking, he squeezed your hand tightly. "You're right, baby. You deserve to eat too."

But before you could reach for the pizza, Hyunjin's hands, which had been holding yours tightly the entire way back from the campus library, wrapped around your waist, and lifted you onto the kitchen counter. He stepped between your legs and leaned in, so you were mere inches apart. "But first, I'd like my appetizer." He grinned, a silent request.

Your heart leapt. Maybe he was feeling just as horny as you were. Wearing a cozy black cable-knit sweater over a white collared button-up shirt, paired with black slacks and brown loafers, he looked absolutely delicious. How were you expected to resist? You pressed a gentle kiss to his lips, taking his black-rimmed glasses and setting them on the counter so you could pull him closer.

He sighed happily against your mouth, and you brought your hands up to grip both sides of his face, pulling him to you. You melded together, tasting each other with a sweet, gentle passion. How could it be this early, and you were already experiencing such strong feelings for him? It just made your resolve to enact this plan even stronger.

Nipping your bottom lip playfully, he let go, carefully setting you back on the kitchen floor, but never releasing your hand. You wrapped an arm around his waist, curling into the warmth of his body. He smelled of clean laundry and wet paint, your favorite scent as of the past three months. When you breathed him in, a sense of calm blanketed your mind, and you smiled against him.

He kissed the top of your head as he served you a plate of pizza, then pulled a chair out and waited for you to sit, before settling in as well, grabbing a slice for himself. He took a bite, his free hand snaking down to your bare thigh and squeezing tight. The two of you ate in silence, your mind temporarily getting distracted by the need for food. The cheap cheese, the only thing you college students could afford, satisfied one of your cravings after a long day of studying. You closed your eyes and smiled, resting your head on his shoulder in contentment. He looked down and met your gaze, eyes filled with affection. "Was all that hard work worth it, baby?" he teased. "You look like you're in heaven."

You shrugged. "What? It's really good, don't you think?"

He chuckled, reaching out with a napkin to wipe some grease off the side of your face. "I just like seeing you happy. Oh, and I'm fucking starving! It makes even this crappy pizza taste amazing."

Wiping your mouth, you smiled in response. God, was he trying to tease you, by being the absolute best boyfriend in the world and wearing your absolute favorite outfit of his? It was time to get your plan rolling, because you wanted this man too damn badly.

Your hand came up, and you stroked his cheek gently. He closed his eyes, leaning into your touch. "You know Hyun, the pizza isn't the only thing that tastes amazing," you murmured, zeroing in on the splotch of pizza sauce on the edge of his lip. Leaning in, you licked it off, getting a taste of the tangy sauce, an intoxicating whiff of your boyfriend following it.

He visibly gulped, looking you up and down nervously. The back of his neck began to redden, but he grinned, trying to keep his cool. He was just too adorable when he got flustered, you thought with satisfaction.

You snatched up his hand and stood up. "You wanna find out what it is?" you asked coyly. "I hear that there's a very good boy who finished all his studies. I think he deserves something sweet as a reward."

Hyunjin's dark eyes lit up with excitement, and before you could react, he was standing up and snatching you into his arms bridal style, carrying you all the way to his bedroom.

"Hyun, you can't just take me away from my food like this!" you cried, playfully smacking his chest over and over. But you hid a smile against his shoulder. How did you know your plan would be so easy?

He smirked, tossing you onto the bed with just enough care so you wouldn't get hurt. "What? You said I would get a treat. If it's the treat I think it is, I would be a fool to dawdle." Then, he sat on the bed, and patted his lap. "Now, what were you saying about something being delicious and sweet, huh?"

"Okay, okay Mr. Impatient." You rolled your eyes. "But first, I want all this off." Motioning to his sweater and button-up combo, you grinned. "I wanna see how hot my boyfriend is."

"Oh really?" he inquired, brows raised. But without another word, he pulled his sweater over his head and unbuttoned his shirt, exposing his slim, yet distractingly toned body. He'd only gotten more muscular since you started dating. He'd always been mouth-wateringly sexy, but with those sinewy arms and defined abs, it was a panty-wetter for sure.

You bit your lip as you visually devoured him. Reaching your arms out to him, you fisted each side of his open shirt, and pulled him towards you. "Okay Mr. Hwang, it's time for your special reward."

He fell into your embrace readily, hands carding through your hair, as you wrapped your legs around his waist, tugging him as close as possible. You cupped his face in both hands, before dipping your head to his, and engaging in a deep, intimate kiss. His tongue slid into your mouth, and they tangled together messily as he nibbled on your bottom lip, causing you to whine against him, begging for more.

"Already so needy, baby?" he teased, eyes narrowing playfully. "I thought you were giving me a present, not the other way around."

You pouted, beginning to grind against him uncontrollably, desperately seeking the friction his clothed crotch gave you. "Did you think I was just going to give up?" you huffed. Before he could reply, you climbed off his lap, and pushed him into the mattress, sliding down his body and unfastening the button on his slacks, tugging them off, along with his boxers.

His semi-hard cock, flushed and pretty, sprang forth immediately, and you grasped him firmly in one hand, admiring him. All pink and long, with a vein down the middle. You knew he went especially crazy when you licked that spot...

Hyunjin watched you, curious eyes shadowed with arousal. "If this is my reward, can I request something?" he asked, his voice turned deep and husky at the mere prospect of you pleasuring him.

You shrugged, nodding. "Sure baby, you can request anything you want."

"Take your top off, yeah? I can't be the only one without my clothes on, and I want to see your gorgeous body."

You obediently pulled your shirt over your head, leaving you exposed in your lacy black bra. Although you hadn't dressed up outwardly, having been studying for hours, this was part of your plan. So naturally, you had to wow him with his favorite pair of lingerie.

And judging from the way Hyunjin's cock instantly began swelling against your palm, your plan was working. He whistled quietly at the sight, starting to thrust himself in and out of your hand, moaning at the sensation.

"Fuck baby, did you wear that pretty number just for me?" He clenched his jaw as he gazed at you, using both of his elbows to prop himself up so he could observe your skilled ministrations.

You smirked, now using both hands to stroke him up and down. "Is there anything wrong with wanting to look pretty for my man?" you asked demurely, before opening your mouth and licking a stripe down the length of his gorgeous cock, marveling at the salty flavor of his precum, which had started beading from the tip and onto your hand.

"Fuck, don't tease me, angel," Hyunjin gritted out, squeezing his eyes shut at the sensation. "Show me how good your mouth is."

Spurred on by your boyfriend's praise, you took him all the way, sucking with vigor as you bobbed your head up and down, saliva dripping onto his stomach. Kneeling on the bed, you arched your back higher, so he could get a nice view of your ass as you worked.

"Shit, yes, just like that baby, I-I'm gonna fucking bust," Hyunjin stammered through swollen lips, fighting between closing his eyes and the desire to stare at you. "Look at your sexy little ass, in the air just for me. You're so hot." Unable to control himself, his hips began jerking up and down at a faster pace, and you began choking on his cock, as he forced it down your throat.

"Yes Hyun, use me however you want," you gasped around him, using your hands to stroke the base, which was slick with spit and precum. "Fuck, you're so big, I want you inside me right now."

"Yeah? You want your boyfriend to fuck you silly?" he panted in desperation, sweat shining on his forehead. "Then get your cute ass up here."

You hustled to lay on the bed, and Hyunjin knelt above you, his cock still fully hard and pulsing with desire. Wrapping your legs around his waist, you pulled him close to you, inviting his cock to rest at the entrance of your pussy. You were so wet, you were soaking through the sheets below you, begging to be fucked.

"Shit, you're really making a mess down there, sweetheart," Hyunjin murmured reverently, sliding the pad of his thumb against your cunt, forcing a desperate whimper from your lips.

"I'm only wet for you, Hyun." You batted your eyelashes at him enticingly, rubbing your pussy against his cock, reveling in the sensation of him against your sensitive nerves. "Please, fuck me?"

"Ah shit," Hyunjin scrubbed a hand down his face, before using his arms to brace himself over you. "How could I say no, when you just gave me the best gift ever?"

"It's not finished yet," you breathed, as you lined his cock up with your entrance, and, pushing your legs against his back, pulled him flush against you.

Taking this as permission, Hyunjin thrusted into you in one harsh movement, until he was balls deep in your tight heat. The air was instantly filled with your and his desperate moans, as he picked up speed, and he was pounding in and out of you, aided by your raised hips and pretty whimpers.

"Yes baby, yes," he panted, the bed shaking and creaking as he fucked in and out of you impossibly faster, wet slapping sounds proof of your arousal. "You fit me so well, squeeze me so tight."

"Please Hyun, touch me," you gasped, sliding your hands into his hair and pulling desperately. This was what happened every time. You would get so close and beg him to touch you, or kiss your neck, or suck your nipples. And he would, every time. But...

"Of course, beautiful," Hyunjin's rough fingers slipped between your legs, as he began rubbing that bundle of nerves vigorously. "Are you close, baby? I think I'm gonna cum, but I want to finish together this time." His hips shook as he tried to stave off his approaching orgasm.

You whimpered against him, burying your face in his shoulder, breathing in his scent. Grinding yourself frantically against his fingers and cock, neither of which had slowed, you silently begged yourself to get there, just finish so you could have your first ever orgasm at the same time as your boyfriend.

"And from now on, you will call me Professor."

Fuck. You took a sharp inhale of breath, cunt tightening as those words, words which had admittedly haunted you for six months, suddenly invaded your brain. And they always did, every time you had sex with Hyunjin.

"Baby, baby, baby, I-I cant hold off any longer-" Hyunjin gasped, before his hips stuttered, jerking a few times, and he finished inside of you with a few choked shudders.

"I-I'm sorry," you whispered, as your orgasm faded, your mind still stuck on a certain math professor. One you hadn't so much as spoken to in months.

Hyunjin deflated at your words. He knew that you had never finished properly with him. You cared too much about him to lie. But it hurt you to see him like this. "I don't know what I'm doing wrong!"

You pressed a tender kiss to his cheek. "You're not doing anything wrong, babe. We'll figure it out."

But you were upset at yourself. Why was it that whenever you merely thought about Changbin in bed, you were immediately pulled out of whatever aroused state you were in, only thinking about him? Because... you'd never felt the way you had fucking him. Even if you had a perfect relationship with Hyunjin.

Had Changbin ruined all sex for you?

Or had you not gotten him out of your system yet?

—————————————

One week later...

You hustled down the hall towards your final class of the day, Advanced Syntax and Sentence Structure. It was one of your favorite courses, and you were always excited to attend.

But not today. No, today, you were in a terrible mood. You had been for the entire week.

Because all you could think about was the fact that you hadn't been able to properly orgasm for over three months. Was it too much to ask? To cum on your gorgeous boyfriend's cock? That was one of the many questions that had been circulating your brain during all waking hours. Along with, was this what having blue balls was like? If so, no wonder men got so touchy when they hadn't gotten laid.

But the real — and perhaps more disconcerting — conundrum was the fact that you couldn't stop comparing your sex life with Hyunjin to your past foray with Changbin. And even more infuriating still? You'd only slept with that gorgeous buff, domineering, smart man once. He was a little, but not too much, older. And yet, he seemed more mature, and seemed to understand a woman's body better than anyone your age. And potentially because of that, you couldn't stop thinking about that single day in his classroom.

And what you hated the most was that you would never get to be with him, ever again.

It wasn't that you didn't want to be with Hyunjin. Quite the opposite, in fact. You wanted to be with him for the long haul. You thought you could even see yourself falling in love with him. But as confident as he was, he wasn't as sexually experienced as some of your past partners. And certainly not as experienced as Changbin.

"He could learn a thing or two from him..." you muttered before you even realized what you'd said, eyes narrowed as you stared down at your shoes. You regretted that thought, wishing you could just banish your hot former professor from your mind.

But before you could second guess your thoughts any further, you ran headfirst into something. Something much too warm and solid.

—————————————

Changbin was overwhelmed.

It was the final month of the last semester, and finals were quickly approaching. He was teaching five courses, the maximum number of classes a professor could take on in a semester. At the time, he thought it would be a breeze. Now, he was dearly regretting that decision.

He pushed his glasses up the bridge of his nose when they slipped down, his gaze buried in his papers while he walked. On top of all his regular responsibilities, a fellow professor and friend had fallen ill, and asked Changbin to sub for their class. He was in the English building, heading there now. In one hand, he held the class's lecture, which he hadn't read. In the other was the Calculus 3000 tests he'd given last week, and had yet to grade, his briefcase around his forearm. He took any free moment to remove a bit of his workload.

Just as he was switching from his lecture to grading the test midair, the wind was knocked out of him, as something — or someone — ran headfirst into him.

"Ah shit!" Changbin grunted, his papers spilling to the floor in a messy heap. Dammit, that was going to take at least a half hour to sort through, he thought grumpily.

"Oh geez, I'm so sorry! God, what a mess of a day..."

Changbin finally looked away from his papers, and back at the person who had run into him. His heart was suddenly thudding out of his chest, tongue feeling wrong in his mouth. Because he would recognize that voice anywhere.

"M-Miss English Major," he croaked, his words broken and awkward. He could feel heat rising up his neck, as he took in the sight of you for the first time in almost five months.

He'd never stopped thinking about you, even after all this time. Whether he was at home alone with nothing but his hand (doing less than savory things), or just sitting in his classroom, exhausted (don't worry, he wouldn't taint that room without you), his thoughts couldn't help but drift back to you. Not only had you shown him what mind-blowingly amazing sex was, but you were also an incredible person. He'd told you the truth, months ago. He'd never met anyone like you. And he still hadn't. And if his body, especially late at night, was anything to go off of, he still wanted you, badly.

But while his memory of that single afternoon with you was clear as a freshly polished window, the intricate details of you had faded overtime. So seeing you now was a punch to the gut, one he would welcome, over and over again.

Because hell, you looked amazing. Even better than what his fantasies continually conjured up. The furrow between your eyebrows when you were distressed, the nape of your neck where a single freckle sat, or your addictive smell, one of orchids and new books.

And your body. He swallowed hard, that lump staying lodged in his throat, making it hard to breathe. Dressed in some kind of distressingly tight cropped t-shirt with the words "Cute Girls Club" written across the tits, he couldn't help but ogle you. Jesus, you were just walking around like that, for everyone to see? And you were doing this, while he sat oblivious, for months? He ground his teeth together in poorly pent-up frustration. How was he getting jealous over you, while you probably hadn't thought about him once? He should really get his shit together, and go to class.

But your eyes were his downfall. That gaze of yours flicked to his, filled with apology (why were you sorry, again?) and... something else. A darkness, one that wasn't there last he saw you. He frowned, all thoughts of abandoning you gone. He carefully studied your features, ones that he'd known so well, terrified that he might forget, or worse, never see again.

Was something wrong?

Your words from a few moments prior echoed in his mind. "God, what a mess of a day..." And upon closer inspection, there was a tension around your eyes, your mouth. Like it was a struggle just to smile.

"Professor Seo." You nodded at him, pulling your bottom lip into your mouth. That tempting, delicious mouth. Changbin tracked the movement hungrily. You averted your gaze, cheeks rosy, like you knew what he was doing. But the mere thought that he might have flustered you flooded him with a sense of relief and pride. But he could still see something was wearing on you.

"Are you okay?" He leaned down so his face was level with yours. Your eyes widened, and he had the urge to grab you, and hold you to him, just for the chance to feel your body again. How had he endured this long outside of your presence?

You shook your head, laughing weakly. "Oh, it's nothing. I wouldn't want to bother you with my stupid shit. Thank you though, Professor." And with that, you made to duck out of his way, and down the hall.

"Wait!" The word flew from his mouth accidentally, but he didn't regret it. Because you turned back around, that tired look still encasing your breathtaking qualities.

"Yes, Professor?" you asked softly. Just the sound of you saying those words brought back an entourage of memories, one that threatened to destroy him. His cock twitched in his pants, and he casually covered himself with his briefcase. Fuck, he could not be getting turned on in the middle of campus, right before class.

He paused. He hadn't thought of what else to say, he just knew that you couldn't leave, not again. "I know we haven't talked in awhile but... you can always tell me what's going on."

You stood there for a few seconds, pondering his offer. The two of you really had gotten to know each other over the semester you had taken his class. He hoped that you felt the same.

"I-it's nothing," you repeated, but there was a quaver of anger hidden in those words. "It's just stuff with my boyfriend. I'm just, well, I'm frustrated-"

But Changbin didn't hear anything past the word "boyfriend". His fists balled themselves at his sides, his breathing came fast and shallow, as he worked his jaw up and down so hard, he felt like his teeth might break. Red colored his vision.

So you had a boyfriend. Who the hell was he? Who had taken his girl from right under his nose? Hadn't the two of you connected like no one ever had? It had felt like soulmate shit, at least to him.

But he supposed he hadn't made another move on you, after your singular rendezvous. And no matter how absolutely incredible it had been, he couldn't expect you to wait around for months. And since you were his student, and he'd been very skittish about any kind of relationship with you before he'd snapped like a taut rubber band, he couldn't blame you if you thought he'd changed his mind again. Maybe even thought he regretted his decision to fuck you in the first place.

But that was so opposite from the truth, it made his chest hurt. He had to do something to rectify it. To get you back. Because you were his girl, weren't you? But what could he do?

"Who is it?" he seethed, voice much angrier than he meant it. But he was just so fucking pissed, and even a little humiliated, that he had his chance, and fumbled, horrifically.

You stared at him, stunned. "You know him," you began. "Hyunjin? We've been together for three months now."

"Oh, the Hwang boy," Changbin scoffed, internally begging his mouth to close, for the next words not to be uttered. But jealousy spurred him on. "Well, there's your problem. There's no way he's satisfying you."

Fuck, he groaned. That was sure to be the end, right? The end of this conversation, the end of a potential re-connection with you. You were going to cuss him out and walk away, never to be seen by him again. His jealousy probably just ruined something that could have been great.

But you didn't do any of that. You just gaped at him, open-mouthed and lost for words. "Well, I- y-you don't know anything!" you stammered, cheeks bright red. "W-why would you think that??"

Changbin paused, caught off guard. Was he... onto something? Was that Hwang boy not satisfying his queen? His beautiful, smart, creative English Major? Were you trying your best to be fulfilled, only for your boyfriend to fall short? Were you sexually frustrated? Yet another onslaught of dirty thoughts berated his mind, of you whimpering and begging your boyfriend to give you an orgasm, and every time, being denied.

That just wouldn't do. He set his jaw, eyes narrowed with misplaced anger. At you, for leaving him. And the Hwang boy, for taking the woman he was just starting to realize the depths of his feelings for. And that jealousy started to coil deep in his stomach, a viper, ready to strike at this golden opportunity.

No, Changbin, he inwardly warned himself. You can't say what you're thinking right now. That would be inappropriate, and grossly assuming that your feelings were anywhere near the same as his. You had a boyfriend, for fuck's sake. There was no way you wanted him anymore. It had been months ago. Things had changed.

He really should go.

"You know, if you're asking for advice... I recommend a more hands-on approach." Shut up Changbin, shut the fuck up.

But again, you didn't leave. Your eyes just flicked back and forth, and you chewed on your lower lip, like you were actually contemplating it.

After another painstaking ten seconds, you spoke. "Do you have a piece of paper?" you asked, eyes zeroing in on the humongous pile still on the floor.

"Oh! Uh, yeah of course!" Changbin practically fell to the ground, scrambling to pick up his papers, trying to look semi-put together while doing so. He snatched up a page from his lecture notes, trying not to let nerves and confusion take over his senses.

You slowly pulled a pen out from the inside of your shirt. Did you store pens in your bra? He salivated at the thought, and his cock stiffened in his pants once again. Dammit, how many times would he get a boner in a mere ten minutes spent around you?

When you realized he was staring, you swallowed. "Uh, English major things," you said hastily, before handing him the pen, face so flushed and pretty, he wished he could reach out and kiss it. When he stared at you dumbly, you added, "Write your number on it. I'll text you." You smiled nervously at him. "If you're serious about your offer, that is."

Changbin had never written anything faster in his entire life. You took the paper from his hand, and he swore you brushed your fingers against his on purpose. A cold sweat broke out across his body, sick satisfaction filling him.

Holy hell, what had he just gotten himself into?

—————————————

You'd always considered yourself to be a reasonably intelligent human being. But making rash decisions, fueled entirely by emotion? That was your fatal character flaw. And today was no different.

But how could any girl with eyes deny Seo Changbin, especially when he was looking sexy as hell in his usual sweater and slacks combo, paired with those glasses that made him look like a big, sexy nerd? His hair was all mussed, and he had heavy eye bags, probably due to lack of sleep and finals fast approaching. And something about that haggard, hardworking professor was your undoing.

And don't even get you started on when he practically started begging you to let him sleep with you one more time, as if he hadn't gotten enough the first time. Damn him for showing up at the same time that you were lusting after him!

So yeah, you were just going to blame this whole messy situation on Changbin. That made everything easier.

Well, not everything. You still had to find a way to breach the subject with your boyfriend.

Of course, you could just pretend that the conversation between you and Changbin never happened, and just go about your life with Hyunjin like normal. And a large part of you, the cowardly part, wanted to do just that.

But a much darker, hungrier side of you wanted this. Desperately. Possibly even needed it. It wasn't that you weren't absolutely obsessed with your boyfriend. Your desperation was, in part, because you were obsessed with him. You wanted this relationship to work so badly, that you were concocting insane ways to help him fully satisfy you.

Something as insane as asking your past hookup to teach Hyunjin how to pleasure you. Because oh, what a remarkable job he'd done at it. Your cheeks warmed at the thought.

Now, you were leaving campus after class, and heading to Hyunjin's apartment. He'd said he was making dinner tonight, and you were both excited and apprehensive to see the result. But the thing that was really stressing you out was deciding how to broach the conundrum you'd landed yourself in, which also happened to be a taboo topic.

You knocked on the door, and you heard a clatter of pots and pans come from within. But you knew you were truly nervous, because you couldn't even focus on the idea of Hyunjin's cooking chaos. You needed to get this conversation over with, now.

"Baby!" Hyunjin shoved the door open, a huge grin on his face. Something red was splattered across his nose, and a waft of tomato sauce emanated from inside. He grabbed your hand, and pulled you into the kitchen, where a pot of sauce was bubbling on the stove, next to some browned ground beef. He grinned, pointing at it proudly. "How does it look?? Amazing, right??"

You smiled, unable to hide your relief. Both at seeing him so happy, and the fact there was no visible mess, yet. "It looks delicious. Is it almost ready?"

He nodded. "The pasta is in the strainer over there, can you grab it for me?"

The two of you finished making dinner together, laughing and talking about how your day went. There was no way you could bring up your conversation with Changbin now, right? You didn't think you could bear to see that gorgeous smile of Hyunjin's slide off his face when he heard that you'd been lusting after another man. Your stomach turned over at the thought. No, you would wait until after dinner.

"As you know, I presented my second art final today!" Hyunjin was babbling, mouth full of spaghetti and meat sauce. "And I have to say, I think mine was one of the best. Not because it was a masterpiece or anything, but some of the others really sucked! Sorry, that sounds rude. They were uh... not good!"

You tried to stay engaged with his story, but your thoughts kept straying, attempting to put together a script of what to say when you inevitably had to confess.

"Baby? Baby? Babyyyy?"

You snapped back to reality. Hyunjin was waving his pasta-filled fork in front of your face, a pout on his lips.

"Ah! Sorry, what were you saying?" you asked, smiling innocently.

He frowned, jabbing the utensil in your face accusingly. "You weren't listening to me?? Babe, what's up? You always listen to all of my stories!"

"I know Hyun, I'm sorry." You reached out and took his hand. Yours was sweaty, so he was sure to know something was wrong. "Today was a... weird day."

He rubbed his thumb over the back of your hand, expression now one of concern. "Weird? How? Tell me!"

So you proceeded to explain how you'd run into Changbin, and relayed the conversation you'd had. Hyunjin knew about your history with Changbin, because you'd told him about it when you'd become close.

So far, he didn't seem to mind that Changbin had asked about your sex life. That was a start. But before you could tell him the insane proposition Changbin had made, you stopped short, cheeks reddening at the thought.

"And?" Hyunjin prompted. "I can tell there's more. After your history, he can't have just walked away."

"No, he didn't," you mumbled, steeling yourself for the big reveal. "He... well, he basically offered to help us out, if we needed it. You know, in bed. And I might have... asked him for his number." You covered your face, as you felt like melting on the spot.

Hyunjin sat next to you, the silence stretching painfully. Suddenly, a hand reached out and grabbed yours, squeezing tightly.

Stunned, you uncovered your eyes, chancing a peek at him. And Hyunjin was... smiling? At you? You took your hands away from your face entirely, gaping at him in surprise. You hadn't expected his reaction. What was his reaction?

"Don't leave me hanging here, Hyun," you managed, laughing shakily as you gripped his hand like a lifeline.

The hint of a smile curled into a full-on grin as he spoke. "You want to have a threesome with Professor Seo, baby?"

You groaned, face bright scarlet. "I-I don't know, I wanted to talk to you first! I haven't texted him, or anything. But..."

"But you haven't been able to cum with me," he prompted. "And... you did with him, right?"

You nodded imperceptibly, unable to utter a word.

"Do you still want to be with me?"

You jerked your head furiously. "Yes! Yes, always, Hyun. I've never connected with anyone more, and I care about you so much. I would only want to do this if you wanted to! I don't want you to think that-"

He laughed, shaking his head. "No I know baby, me too. I just wanted to make sure. Because... I've always thought it would be hot to see you with another guy. Did I ever think it would be my former math professor? Hell no. But if I could join too, then I would do anything to make you happy."

Your eyes widened further, and it felt like your heart was going to explode, as you stared, speechless, at your boyfriend. Was he saying what you thought he was saying? Did he... want to do this? Not just for you, but for his pleasure as well?

"S-so you're saying that-" you stumbled over your words.

Hyunjin leaned in, pressing a gentle kiss to your lips. "Go text him, baby."

Was Changbin making a dreadful mistake?

Standing outside the door of Hyunjin's — your current boyfriend's — apartment, a wave of self doubt threatened to crash over him. Had he completely screwed up agreeing to share a taken woman? He never thought he would find himself in a situation even close to this. He wouldn't do this for anyone.

But you were different. You were you. Creative and witty, passionate in a way he'd never before witnessed, in both life goals and in bed. And on top of it all, he'd connected with you on another level. And now, he couldn't get you out of his head. This would all be worth it to sleep with you one more time.

So he reached his hand up, and knocked on the door.

After a solid twenty seconds, where Changbin could hear nothing except the terrified thudding of his own heart, the door swung open, and... there you stood. Donning nothing but a white silk robe, and a crafty smile.

"Come in, Professor," you said, voice soft and sultry, words dripping like honey off your full, cherry-red lips.

Changbin gulped, following you into the living room, mouth dry. In the soft orange light and the mystery of the night, you looked so delectable, he wanted to pry your legs open and take you right there, on the brown leather couch.

"This is Hyunjin's apartment." You swept your arms around the space, flashing him a flirty grin that had his stomach clenching with desire. "Not that you'll be seeing much of it, outside of the bedroom."

Changbin closed his eyes, trying not to pop a blood vessel from the boner already growing in his pants. Taking a precursory look around, he was impressed with the aesthetic Hyunjin had managed to curate on a college student budget. A mix of artsy and chic, with a smattering of eclectic colors that somehow all harmonized with one another, it truly looked like a home. It was much cozier than Changbin's townhome, which featured a lone picture of him and his close friends at the beach last year, and one gray couch in the living room.

The abode of a true bachelor, he sighed to himself. If he ever wanted to invite you over, he would have to spruce it up, majorly.

The two of you entered the bedroom, where Hyunjin was sitting at a desk, tapping away on his phone like this was just your average evening. Did you do this often? The disturbing idea forced its way into his mind.

You smiled at him again, and the thought dissolved instantly. Hyunjin looked up, and immediately set his phone down, a look of apprehension and cautious excitement crossing his face. Was he just as nervous as Changbin?

"Well, since this is our first time doing anything like this," you began, answering his question, "Hyun and I just want to make sure that you're sure that you're comfortable, and you want to do this. A-and we wanted to let you know that we're open to anything, since you're helping us. Right, babe?" You cut a glance at Hyunjin.

The man nodded, swallowing thickly. "Yeah, I want to pleasure my girl. And... she said she had a great time with you before." He ducked his head.

"And he doesn't mind sharing me, for the night," you added quietly, blushing prettily.

Changbin bit his lip to keep from groaning aloud. Fuck, how did you know exactly how to turn him on?

"Well, if you two are comfortable, then so am I," he started, turning to you, his voice lowering an octave, deep and hoarse. "As long as you're willing to follow my instructions."

You immediately snapped to attention at his tone change, back going taut as a coiled spring. "Y-yes, Professor. Anything you want."

Hyunjin watched with dark eyes, as he ran a hand through his hair. "Fuck baby, I didn't know rough language turned you on so much. I like it."

"So, what's the real problem here?" Changbin asked, wondering exactly how much he could squeeze out of this little deal. "Is it him eating you out? The sex? Both?"

"It's not the sex itself," you paused, chewing your lower lip. "It's just that I can't cum. I-I don't know why, but I just can't get there."

Changbin nodded slowly. "Well, why don't we see what we're working with, huh?" He pointed at Hyunjin. "Show me how you eat her out."

You smiled at him, lip wobbling from nerves. "Before we start, I have a little surprise for you. For both of you."

Changbin watched, entranced, as you slowly removed your robe, body moving oh-so-sensually, revealing matching white and red lace lingerie that left nothing to the imagination. The lace across your perky breasts, the ribbons gracing your silky thighs, everything made his mouth water. You smiled, a sultry look, directly at Changbin, and he was instantly brought back to that day in his classroom, when he'd finally given in to the temptation to take you. That day had been a blur of hot red, as he blindly followed every urge he felt.

As he grabbed you around the waist and pushed you into the mattress, planting a hard, searing kiss to your awaiting lips, it felt even better than that day. You were no longer in your school clothes. You were dressed so pretty, all for him. And he would take anything you were willing to give.

And give you did. Wrapping your legs around his waist and pulling him closer, moaning so sexily against his lips, slipping your tongue into his mouth, you tasted of a desperation that he lapped up like syrup. Your hands slid into his hair and tugged, as the two of you explored one another like it was simultaneously the first time, and the one hundredth.

"I missed you, Professor," you whispered breathlessly, pupils blown wide as you finally broke the kiss. "I was scared you wouldn't agree to come tonight."

He grinned, releasing you and allowing Hyunjin to take his place. "I could never say no to another chance with you, beautiful."

Hyunjin knelt in front of you, licking his lips eagerly. "My irresistible baby," he crooned at you, pulling the white thong to the side and running his thumb through your already soaked cunt.

You whimpered, immediately becoming putty beneath your boyfriend's touch. Sliding a hand into Hyunjin's long, wavy hair, you tugged him closer, lip pulled between your teeth, waiting with baited breath. "Please Hyun, your tongue," you begged.

Changbin watched with reverence, trying to memorize every little reaction, every movement you made.

Hyunjin acquiesced to your pleas without question, shoving his head between your legs as he opened his mouth, latching onto your clit and sucking hard. His fingers worked in tandem with his tongue, as they both fucked in and out of you with abandon.

Your hips bucked against his ministrations, incoherent words of desperation spilling from your lips as you reached for Changbin, eyes watery and filled with need. A sheen of sweat already glistened across your forehead, and Changbin was at your side in an instant, pressing kisses against you, relishing the salty taste.

"You like that huh, sweetheart?" he growled, a deep rumble in his throat, as he moved his lips down your neck, across your collarbone, and to your breasts. "You like the feeling of your boyfriend eating your wet little pussy, while your professor sucks your nipples?"

You cried out, and Hyunjin only increased his movements in response, the wet squelching of your cunt mixing with your garbled moans. Changbin latched onto a raised nipple and sucked harshly, biting at them, and making you squirm with sensitivity beneath his grasp. Hyunjin continued to fuck his tongue in and out of you, his fingers stroking you desperately.

You gripped Changbin's arms, and he knew your orgasm was looming closer and closer. You squeezed your eyes shut, hands moving to his hair and pulling as you wrapped your legs around Hyunjin's head, entire body shaking violently.

"Y-yes, right there!" you pleaded, rocking your hips, hungry for more. Your gaze locked on Changbin, hot with lust, and his cock twitched in response. "Please, don't stop!"

Hyunjin moaned raggedly against you, sending vibrations shivering through your sensitive nerves. But no matter how hard he tried, no matter how amazing it felt, your orgasm... subsided. Disappeared. You whimpered softly, heart sinking.

"Did you cum, love?" Hyunjin asked after a moment. But he already knew the answer. You hesitated, then shook your head.

"It looked like you were really enjoying it," Changbin mused, pressing another kiss to your chest and standing up. "And not to be weird, but I think he was doing a good job."

"Do you like it when Professor Seo says mean things to you, baby?" Hyunjin interrupted, continuing to rub gentle circles against your soaked pussy. "Every time he said something mean, you practically gushed on my tongue."

You averted your gaze, cheeks red. But you nodded anyway. "Yes, I think... I think when he's mean to me, I get really turned on," you whispered, finally meeting Hyunjin's gaze. "I think it really pushes me over the edge."

Changbin nodded slowly, finally starting to understand. "Gorgeous?" he barked, and you stared at him with those wide, alluring eyes. He had to tear his gaze from yours to continue. "Hyunjin? You said you were willing to learn. Why don't you watch?" Changbin held his breath, hoping that Hyunjin wouldn't call him on his shit. Because if he was being honest, he wanted you to himself, just this once.

Hyunjin paused, glancing at you in askance. You nodded silently, sending him an encouraging smile. With a jerk of his head, he moved slightly off to the side, while also giving himself a good view of what was happening.

"I'm only doing it because my girlfriend wants this," Hyunjin warned. "And because I have no idea why she can't finish. I want to please her."

Changbin chuckled. "Of course. And I'm here to help." With that, he grabbed both of your legs and spread them wide, positioning his hips between yours, leaning down, and capturing your lips with his.

You moaned loudly against him, wrapping your legs tightly around his waist, and grinding your soaked pantie-clad pussy against his pants. "Can I take your shirt off, Professor?" you whispered breathlessly, fingers already tugging at the hem.

He nodded, the heat of embarrassment and pride climbing up his neck. He helped you remove his shirt, and then unbuckled his belt and pulled his pants off, sighing in relief. His cock had been pressing against the confines of his jeans since he arrived.

You rubbed your hand against his cock through his boxers, before expertly tugging them off, and stroking him to full hardness. He gritted his teeth so hard they hurt, his eyes shut tight as he tried to reign in some semblance of self control. He'd missed you so desperately, he ached.

"Don't tease me, you little slut," he ground out, hips rocking against your touch insistently.

"I'm not doing anything!" You blinked up at him, a devilish smile on your face, continuing to pump him, heavy in your hand. Fuck. His cock swelled further. You really were just a minx, weren't you?

"I'm warning you, kitten," he hissed, eyes narrowed. When you didn't stop, he grabbed both of your hands, and pinned them by the wrists over your head, ignoring your squeals of protest. "That's it, I told you," he spat, positioning himself outside your entrance, which was dripping onto the blankets.

"P-please Professor!" you gasped, panting with need. "Fuck me, please."

"You don't deserve it, spiting me like a whore," he snapped. But he was so fucking turned on, he couldn't tease you for long. With a strangled growl, he filled you with one thrust, knees buckling at the heavenly sensation of your tight heat enveloping him, like you were made to fit his length.

"God yes Professor, please fuck me faster." You clung to his arms, tears streaming down your face as you dug your heels into his back, pushing him deeper inside you.

He nearly choked on his words, stars winking across his vision, as he began pounding in and out of you, balls slapping your pussy, the bed rocking with the power of his movements. "Fuck yes, take it," he snarled. "You'll take everything I give you." Was this what heaven felt like? You were so warm, molded to him so perfectly. His hips snapped against yours, all that pent-up tension spurring him on as he gave you everything he'd fantasized about over all these months.

"O-oh yes, whatever you want Professor," you panted, warm cunt spasming around his rock hard cock. "Fuck, I think I'm gonna cum, please Professor, can I cum?" You reached your hand out to Hyunjin, and he immediately accepted, as you gazed pleadingly up at them both.

Without you having to ask, Changbin slid a hand down to your drenched, swollen clit. He rubbed fiercely until you were trembling against him, gasping in pleasure. Hyunjin watched, entranced, which sent a thrill of excitement zipping through Changbin, spurring him to pick up speed. God, you felt so fucking good. How had he spent this many months without indulging himself in your glorious body?

You clung to his muscular arms, sobbing and babbling his name incoherently, pussy contracting, hips shuddering. Changbin could feel his orgasm coming, but he staved it off. He couldn't finish already, in the first round. He was doing this for you and your pleasure.

"Cum for us, pretty girl," he commanded, punctuated with a harsh slap to your ass. "Cum like the slut you are."

You cried out, cunt so tight it felt like you were suffocating him. He couldn't breath, as you shook like a leaf, body taught, mouth opened in a wide "o". Your hand slid into his hair, tugging, as your hips shook and jerked uncontrollably.

"F-fuck Professor, Hyun!" And with a wail, you finally toppled over the long-awaited edge, clinging to both men as you fell apart around Changbin's pulsing cock.

He fucked you through it, gently stroking your clit, and reveling in your shivering, sweaty perfection, until you whimpered from overstimulation. He gently pulled out, and allowed Hyunjin to switch places, and hold you.

"Oh my god," you panted, curling into your boyfriend's arms, catching your breath. "That was- that was amazing."

"So what do you think, Hyunjin?" Changbin tried to act nonchalant, like he hadn't just had world-implodingly incredible sex. There was no way around it. He was addicted, and he needed more. But he had to stay true to his word, and give Hyunjin his turn. "Are you ready to try it yourself?"

Hyunjin paused, gazing down lovingly at you in a way that made Changbin's heart squeeze. "So, you like it when Professor Seo says mean things to you..." he said again. He slowly began removing his shirt, your eyes tracking him hungrily.

You nodded, cheeks still flushed with post-sex elation. "I don't know why, but I think it's really hot," you murmured.

Hyunjin brushed a strand of hair from your eyes. Then, he spoke.

"From now on, you will call me sir."

The atmosphere immediately changed, like all the oxygen was sucked out of the room. You stared at your boyfriend, usually such a sweet person, in shock. Changbin hid a laugh. Apparently, Hyunjin had caught onto the fact that you loved calling him "professor" in bed, and got turned on by the degrading nicknames and occasional spanking. But a single nickname wouldn't be enough to truly please you in bed. He would have to act the part, too.

But apparently, Changbin had no reason to be concerned.

"Climb on up here, and fuck me like the slut you are," Hyunjin demanded, slapping your ass, as he watched you expectantly.

"Y-yes sir!" You scrambled to follow his demands, eyes still huge with nervous excitement. You unzipped Hyunjn's pants, and helped him strip off his boxers, allowing his long, pretty cock to spring free. He tugged his shirt off, and you stared in awe at his muscled torso. Changbin smirked down at you in satisfaction. At the end of the day, you just wanted to be dominated.

"Okay angel, start grinding that wet little pussy all over him, okay?" Changbin instructed, wanting to see how you would react to him controlling the situation.

You whined, but nodded, spreading your legs and rubbing yourself all over your boyfriend, causing him to grit out a moan, eyes squeezed shut, as pleasure washed over him.

"And since she likes you to dominate her, maybe adjust her to where you want her, before fucking her," Changbin prodded Hyunjin, who immediately opened his eyes, and grabbed your hips with rough hands.

"Yeah, right there," Hyunjin hissed, pressing you harder against his length, which was aching between your slender thighs, as he moved you against him. "Be a good girl, and let me fuck you how I want."

Your lip wobbled, and you nodded, clinging to the threads of your desire. "Y-yes Hyun- I mean, sir. Please take me now."

Hyunjin's eyes flicked over to Changbin, who just eyed him intently. With that silent approval, Hyunjin lined himself up outside of your aching cunt, and drove himself home, filling you to the brim.

Instantaneously, the room was filled with a chorus of both of your moans. You gripped his slim arms tightly, leaving moon-shaped crescents on his skin, as his veins became more prominent beneath your hands. He growled raggedly against your ear and his hips snapped up against yours, power growing and growing, as you cried into his chest.

"Y-yes, fuck me harder!" you begged, tears wetting your lash line.

"What do you call me, my little slut?" Hyunjin ground out, possessive gaze burning a trail across your skin.

"S-sir, please!" you implored, pressing repeated kisses across his hard pecs. "More!"

"Touch her," Changbin ordered. "She's shaking like a little bitch, it'll make her fall apart around you."

Hyunjin reached a hand between your legs, rubbing rough circles across your aching clit, causing you to shudder and grind yourself needily against him.

"Be gentler, she'll get rug burn if you go much faster," Changbin snapped, and Hyunjin slowed down, stroking you with a tender touch.

"O-oh fuck, I think I'm close!" you gasped, chest wracked with sobs of pleasure as you bounced yourself on your boyfriend's cock, squeezing him so tight he struggled to breathe. "Please don't stop sir, please! Can I- can I cum-"

"Yes angel, cum on me like the whore you are," Hyunjin bit the shell of your earlobe, not relinquishing his relentlessly fast pace in and out of you.

You tumbled over the edge, mouth open on a soundless cry, nails digging deep into his arms, as you trembled around him so violently, he had to grip you hard to keep you stable, lights winking in front of your eyes as you reveled in the sensation of your boyfriend balls-deep inside you. Your pussy was made for him, made for Changbin. Made for the two of them. Small whines of Hyunjin's name were the only things to escape your kiss-swollen lips, as you rode out your high.

Hyunjin's hips stuttered as you came, the warmth and wetness of your perfect little pussy squeezing him so tight, milking him dry. He thrusted his hips messily in and out of you a couple more times, before spurting a load of white liquid into you, fucking the mix of both of your cum into your tired body.

You collapsed on top of him, a sweaty, but satisfied mess. "You-you-" you babbled softly, reaching up and running a hand through his hair adoringly. You glanced up at Changbin, a shy smile on your face.

Changbin grinned down at you, a bit uncomfortable. Should he still be here? "How was that, love?" he asked, voice a deep rasp.

"I-it was amazing Professor," you breathed, a look of wonder in your eyes. "Thank you."

Hyunjin glanced at Changbin, an uncertain look crossing his face. "Would you like to... join us?" he offered, glancing at you fleetingly. "I bet she'd enjoy it. You're down for another round, right angel?"

You turned around, having been kissing up and down Hyunjin's sweaty neck. You stared up at Changbin with a look that had his cock instantly springing to life, and a groan rising in his throat. "I would love for you to join, Professor," you breathed, presenting your ass to him like a dessert on a platter, smiling coquettishly at Hyunjin. You added, "I'm always ready, if it's with both of you."

"Well shit," Changbin growled, striding over, hands clenched at his sides. "How could I say no to that?"

You climbed back onto Hyunjin's lap and gripped his cock, already ready for a second round. You lined up his hard cock outside of your pussy, which was still dripping wet. You closed your eyes, biting your lower lip in anticipation, before slowly impaling yourself on his perfect length.

The two of you let out simultaneous moans of delight, as you began bouncing up and down on top of him, the slapping sounds filling the room, as you squealed and whimpered with tantalizing desire.

Hyunjin grabbed your ass, fucking you over and over on his length, moving you rapidly, in tune with his own pleasure. "Fuck, you're an eager little slut tonight, aren't you?" he hissed, eyes glazed over with unbridled ecstasy, as he drank in the sensation of your pussy clenching around him.

"Fuck me harder, sir!" you whined, hands pressing into his broad chest, as you looked back at Changbin, who was drinking in the sight before him with relish. "Professor, aren't you going to join in? I've always wanted a thick cock inside my ass."

A rumble vibrated inside his throat. From the sound of it, you'd never been fucked by two guys at the same time, and not at all in your ass. Maybe you'd even dreamed about it being him. And the mere idea of that had him seeking a bottle of lube, which sat on your nightstand, and starting to prep the two of you. His heart thudded in his chest, just thinking about how tight you would be.

"If my perfect babygirl wants me there, then I'm happy to oblige," he growled through the pleasure, and you shook your ass at him in response, as you continued to roll your hips against Hyunjin, teasing desperate moans and hitched breaths from his lips.

He began running his pointer finger against the puckered entrance, and you trembled beneath him, clenching around Hyunjin, who growled a curse.

"Relax, baby," Changbin crooned, inching his finger slowly inside of you. "I need to stretch you out before you can even hope to take me."

You choked on a gasp at the foreign sensation, trying to turn around and look. But Hyunjin gripped your jaw to keep you facing him, as he continued thrusting in and out of your pussy, his movements becoming sloppier by the second. So instead, you tangled your hands in your boyfriend's long hair, desperate, ragged sobs muffled by his chest, as he continued to have his way with you.

"Does that feel good, angel?" Hyunjin stroked the flawless skin of your back, as he snapped his hips up against yours, keeping a cruel pace despite the fact you'd gone boneless on top of him.

You let out a broken moan, nodding your head as you pressed feverish kisses to neck, and down his chest. Hyunjin shuddered at your touch, continuing to pound into your ruined cunt.

"Just like that, baby," Changbin praised, kneading the soft skin of your ass, as he gently removed his finger, and inched the tip of his cock past the tight ring of your hole. He trembled at the sensation, vision going foggy with pleasure as he rocked his hips further against you, until he was halfway inside.

"A-ah shit Bin- I mean, Professor!" you cried, clenching around him instinctively. "Fuck, you're huge."

"You'll take him, like the slut you are," Hyunjin barked, pulling your hair so you met his gaze. "I bet you like him stretching out your ass like that, huh?"

"I-I-" you stammered, face reddening. "Y-yes sir, I love it," you croaked, voice cracking, as pleasure threatened to overwhelm you.

"Tell him what you want," Hyunjin prompted, and you keened against him, arms wrapped around his neck as pleasure thrummed in your veins.

You slowly turned around to face Changbin, who swallowed hard. He was desperately trying to fend off his already incoming orgasm, but that fucked out look you were giving him was making it damn near impossible.

"Please go deeper, Professor," you whimpered, voice throatier and more strained than he'd ever heard. "Don't be gentle, I can take it."

"Fuck, kitten," Changbin uttered, steeling himself for the blinding pleasure that was sure to come. With that, he rolled his hips against your plush ass, and buried himself to the hilt in one harsh thrust.

The movement drove Hyunjin's cock even deeper inside of your aching pussy, causing the man to let out a surprised, guttural moan. He hit the soft spongy part inside of you that until now, only Changbin had found, and you were shuddering and begging for more, both from the foreign sensation of two men inside of you, and the euphoria of your boyfriend pleasuring you like he never had.

Fuck, this was going to kill him, was all that echoed through Changbin's muddled mind as he slammed in and out, lost in the suffocating tightness of you, the way you smelled, looked, sounded, as he destroyed you. Even as you clenched around him, he didn't let up his pace, pulling out all the way, only to drive himself home each time. No woman had affected him in the least. Now, he couldn't help but become drunk on your very essence.

"Sir, Professor, I think I'm close," you whimpered, words slurring together you writhed between them, pussy contracting around Hyunjin like a vice. "C-can I cum now?"

"I'm close too," Hyunjin wheezed, his hips jerking up and down uncontrollably, as he pulled you down for a messy kiss, full of tongue and teeth. "Cum with me baby."

"Professor, p-please cum inside me?" You shuddered against him, as he leaned down and nipped the shell of your ear, hot breath fanning against your cheek.

"Shit, I'm already about to bust," he growled, voice strained as he continued to hammer his pulsing cock in and out of you. But he was starting to lose control. You did this to him, made him go insane. "Are you proud of yourself, you little whore? Making me lose my composure like this? Having your professor cum inside you? Fill you up so well?"

"Oh my god, yes!" you wailed, your entire body arching against the two men who held you between them, tremors wracking your body in waves. Hyunjin was stroking your clit in messy circles, sucking on your neck as he murmured sweet nothings against your skin. "Fuck, you both feel so good, I-I'm gonna-"

And before you could finish your sentence, you let go for the last time, entire body quivering with the orgasm you'd been desperately waiting for, until tonight. You clutched Hyunjin's hair in your hands, back bowing into Changbin's shuddering hips, as you finished around both men, in a whimpering, spasming mess, crying incoherently, the only words Changbin could understand being "sir", "professor", and "please".

Hyunjin finished next, gasping out your name as he bullied his throbbing length into you with growing need, letting out soft moans and whines, those full lips devouring yours hungrily, as he fell apart, spilling his load inside of you, milky cum leaking from your pussy down your leg, and onto the blanket.

Changbin was the last to get there, as he gripped your slender waist so tightly in his rough hands, he thought he might break you. His balls contracted painfully, as he trembled above you, the sensation of you squeezing him as you came almost causing him to pass out. "Mine, mine mine," he repeated, harshly sucking the skin on your neck as you nearly collapsed underneath him. But he pulled you up, and held you flush against his chest, continuing to pound mercilessly in and out of you, grunting and growling into your soft hair. His hips twitched and jerked, and he came inside you, so hard he had to hold onto you for purchase.

The three of you collapsed onto the mattress, your tongue lolling from your mouth, completely fucked out, body still wracked with the shockwaves of the intense lovemaking. Hyunjin curled into you, becoming the little spoon, as he kissed the backs of your hands, murmuring praise upon praise.

"You did so good, pretty girl," he murmured adoringly, as you continued to play with his hair, kissing up and down his neck and giggling sleepily.

Changbin watched the two of them, a distinct sensation of discomfort washing over him. He'd done his job, which was helping your and Hyunjin's sex life. And now the two of you were clearly happy without him. He should probably see himself out.

But as he started to grab his clothes and get dressed, you rolled over to face him, a confused look on your face.

"Bin, where are you going?" you asked, voice hoarse with overuse. You looked as beautiful as ever, hair wild and messy, skin glowing after getting properly fucked by the two men you were obsessed with.

Changbin swallowed, forcing himself to be cordial. "I thought now that I did my job, I should leave."

You reached a hand out to him, a pleading smile lighting your face. You glanced at Hyunjin for approval, and he nodded. "What if I didn't want you to leave, Professor?"

Changbin smiled, cheeks warming. "Then I'd stay for as long as you like."
