Summary: Kyuhyun's twin sister, Jihyun, goes a little too far when trying to seduce Kyuhyun's latest love interest, Sungmin.
A/N: there will be TWO versions, not just one.



The buzz of the cafeteria was deafening in Kyuhyun’s ears as he watched his boyfriend, Lee Sungmin and his twin sister, Jihyun talk from across the room. It’s been five months since Sungmin said yes to Kyuhyun and he couldn’t be any happier than he has been for the past five months.

Kyuhyun was in love to say the least, but who wouldn’t be in love with Sungmin?

Kyuhyun’s eyes ghosted over his boyfriend with his teeth digging into his lower lip to rid the tender smile fighting to make its way known.

First, he started at the thick, glossy burgundy locks that were the envy of every girl. Next was his round, rich, dark brown eyes that had a certain indefinable glint to them - enthralling and sensual, with a stroke of mischief, to the smooth, ample cheeks that would give the older a naïve, youthful demeanor whenever he would smile, the sultry, M-shaped lips with his insatiable silky feel, etc.

Appearance wasn’t the only thing Kyuhyun was in love with. Unlike Kyuhyun, Sungmin was bashful, compassionate, charming, docile, friendly, a complete saint. He was active, captain of the martial arts team, yet he never ran out of time for the younger. He was smart, straight A’s and in the top two percent along with Kyuhyun. He volunteered at the local orphanage and tended to drag Kyuhyun along. Instead of helping out like Kyuhyun was supposed to, he would primarily admire the way Sungmin interacted with the kids, always smiling and laughing, making Kyuhyun’s heart skip a beat when he would glance over at the younger with that tender smile and melting glance.

In total, Kyuhyun thought Sungmin was perfect, but so did everyone else…including his twin sister.

Kyuhyun’s eyes narrowed at the sight of Jihyun’s hand resting on Sungmin’s thigh underneath the table. He wasn’t stupid, he saw all the flirting which Sungmin seemed oblivious to. Kyuhyun didn’t say anything, resorting to only glares and hoping Jihyun would stop this act, but she hasn’t stopped for the past 17 years.

Since they were young, the two shared everything - clothes, responsibilities, friends…crushes. Kyuhyun knew he was gay since he was young, merely eight years old when he found himself crushing on the popular boy in the class, Siwon. Naturally, he told his younger twin sister. Later that week he found the two kissing behind the slide. Jihyun told him Siwon kissed her and of course, he believed her.

His next crush was two years later - none of the boys were really that appealing to the eyes to Kyuhyun - on a guy named Jongwoon, a transfer student who was a little wonky in the head. Nonetheless, Kyuhyun liked him and told Jihyun. A month later, he watched with a thumping heart as Jongwoon strode up to him and Jihyun with a rose, only to try and muffle his cries in the boys bathroom later as Jongwoon handed Jihyun the rose and kissed her on the cheek, missing the slight smirk on the younger’s face as he rushed off before tears could spill.

The trend sustained, but the discoveries got worse and worse until he caught her and his latest ex having sex in the showers in the locker room.

Now, he was with Sungmin and he’ll be damned if he was going to let Jihyun snatch this one away from him.

With that determination, Kyuhyun strode over to the table where Sungmin was skimming the cafeteria, seemingly searching for him while Jihyun tried to gain his attention. The older twin cleared his throat before dropping his tray in the space between the two.

“Kyu! I was just looking for you, what took you so long?” Sungmin’s lower lip jutted out as he scooted over to make room.

Kyuhyun chuckled before leaning down to give the older’s lips a brief kiss. A faint dust of pink spread across the older’s cheek before he looked down, glancing shyly at the younger.

“Just admiring the view,” Kyuhyun winked before tucking into his meal.

Sungmin’s blush deepened as he playfully smacked the other’s arm. Both of them temporarily forgot the presence of the youngest on the opposite side of Kyuhyun as they talked about school - more like Kyuhyun ranting on the “slow, dim-witted” population of the school (about 99.98% of the school, including teachers) while Sungmin listened with an amused look in his eyes and a fond smile on his lips.

Jihyun scowled at being forgotten as she pushed around the food on her plate. She wasn’t sure if Sungmin was playing hard to get or was just plain stupid in seeing her advances. Usually they’d succumb by now seeing as it’s been five months since she’s started her task of seducing Sungmin, but no such luck.

I will get you Lee Sungmin, Jihyun ruminated before pushing herself up and walking out the cafeteria.



Despite how he looked, Sungmin was anything, but naïve.

Though at first, the seemingly innocent touches didn’t register in his head as flirting, time passed and it dawned on him what exactly those touches and whispers in his ear implied. Concerned about how Kyuhyun would react against his sister (or the slight chance that he accuse Sungmin of lying and trying to seduce his sister), Sungmin kept his facade of naïveté.

Kyuhyun was something else, Sungmin figured long before they started dating. His soon-to-be infatuation started the second a gangly, disarrayed freshman stumbled into his Calculus class with his black, crinkly disheveled hair and glasses nearly falling off of his thick nose. When said boy made his way to sit next to Sungmin and turned to say hi only to immediately drop his jaw, he knew it was going to be a good year.

Kyuhyun introduced himself to Sungmin on the second day together with a deep flush on his cheeks. Sungmin giggled and asked if he was talking to his crotch or him.

A year passed with the two growing closer and closer every day. Sungmin often threw pick-up lines at the younger, giggling every time Kyuhyun would slightly flail and sometimes find himself looking up at the older from the floor.

Summer soon came and Sungmin grew worried when Kyuhyun hadn’t spoken a word to him for the past two weeks only to be informed the younger was in the country side of Korea without internet or signal until the day before school started.

The next time Sungmin saw Kyuhyun had his breath hitching as he watched the younger enter the school. Long gone was the stick-thin, awkward teenager that Sungmin knew since the first day he saw Kyuhyun. What he was staring at was a lean, long(er)-limbed young adult with wavy, thick locks covering his forehead and the tips of his ears along with a new wardrobe. No more slacks with the sweater vest (though he did admit that he would miss the attire). Instead Kyuhyun adorned a deep, grey, thin v-neck showing off his newly defined muscles and that glorious neck, black skinny jeans that hugged his bottom-half in the all the right places and black boots. His thick lips were stretched into a smirk as he strode over to Sungmin with a single rose in his hand.

He was a completely different person with this confident aurora…well almost completely different, Sungmin thought as he watched the younger trip over his own foot in front of Sungmin.

Sungmin giggled as he peered down at the flushed Kyuhyun holding the rose high in the air. The older plucked the rose from his fingers and helped the younger up. Kyuhyun, familiar stutter and all, timidly asked Sungmin to be his boyfriend in which he answered with his lips.

Sungmin giggled as he thought back to the shocked expression on Kyuhyun’s face after the peck. He still couldn’t get over the fact that Kyuhyun choose him. The third-year palmed his cheeks and shook his head as squeals escaped his mouth. The thought of Kyuhyun being his sent tingles all over his body and to this day his heart pounded when he locked eyes with the younger.

A vibrate near his thigh shook him out of his thoughts as he glanced down at the glowing screen of his phone. It was a text from Kyuhyun.

From: Kyu-kyu♥
To: Minnie-ah~
I have a surprise for you, come over quick~!

A wide grin stretched on Sungmin’s face as he jumped up and hurriedly put on his shoes, barely putting on his jacket as he raced out the door.



Sungmin arrived at the Cho household, pausing at the entrance of the drive way. Kyuhyun…was just past that door and up the stairs. A grin spread on his face as he headed up the steps and knocked on the door. A minute passed before he could hear the lock turn and the door slowly opened. Jihyun poked her head out and smiled before opening the door all the way and greeting the other.

Sungmin smiled politely before raising an eyebrow at her attire. The younger adorned a black, silk short robe with white slippers and her hair was carefully styled, curled to perfection with light make-up.

“Are you heading out?” Sungmin asked as he shrugged off his jacket and kicked off his shoes.

Jihyun nodded and took Sungmin’s jacket, fingers subtly sliding over the others.

“Kyuhyun’s out right now, he said he would be right back. You can wait upstairs in our room.”

Sungmin bowed in thanks before striding up the stairs, two steps at a time. He glanced back only to find Jihyun right on his tail.

“I think I can find your room by myself.” Sungmin chuckled nervously, glancing at the girl before turning towards the twin’s shared room.

Jihyun laughed before rolling her eyes, slapping the others arm lightly.

“Silly, I know that. I just need to get something from there.”

Sungmin shrugged at the excuse and opened the door, stepping inside before sitting on the edge of Kyuhyun’s bed. His eyes followed Jihyun as she looked around the room, pouting. She stomped her foot before turning to Sungmin and her eyes brightening.

“Oppa~! Do you think you could help me?”

Sungmin raised an eyebrow in question, inquiring her to continue.

“Can you tell me how my outfit looks?”

Jihyun sounded so innocent that he agreed. Jihyun told him to close his eyes and he obeyed. He could hear her robe falling to the floor and the sound of shuffling.

“Okay, open them.”

Sungmin’s eyes slowly opened, only to squeak in shock at the sight before him.

Jihyun stood not even a foot away in black, lace lingerie. A sheer merrywidow hugged all her curves in the right place with satin bows running down the middle and completed with a lace trim and garters connected to black stockings. Her breasts were jutting from the seemingly too small built-in bra - they, her breasts, were a little big for her small body type, but that’s what probably attracted a lot of men to her. Her skin was hairless and pale, another one of her main features that allured men into her traps.

Sungmin was too shocked to notice Jihyun maneuver into his lap, hips grinding down onto his. A smirk made way on her face when she noticed he wasn’t moving. Her hands sought his as she nuzzled his neck, nipping at the flesh. Once her hands found purchase of his, she placed them on the sides of her hips, massaging the back of his palms with her fingers before pushing them up and front to cup her breasts.

Sungmin snapped out of his trance once a moan slipped past her lips. His hands that were previously massaging her breasts (courtesy of Jihyun playing puppet) were now pushing the girl back harshly, fury spelled clearly in his posture as he stood up.

“What in the actual fuck do you think you’re doing?!”



Kyuhyun grunted as he shifted the grocery bags from one position to another, groaning when it didn’t seem to help a bit.

“Stupid Jihyun giving me a stupidly long list of stupid groceries to buy, stupid,” Kyuhyun hissed, sighing in relief when he could see his house coming up.

It was an hour ago when Jihyun shoved a long list of supplies and food they supposedly needed and forced him to go out and get them. Kyuhyun spent most of his time cursing her than actually looking for the groceries. Some of the stuff they didn’t even sell in Korea! Kyuhyun ‘tsk’ed’ at his sister as he climbed the steps up to the front door.

After he settled down the bags, he opened the door incase Jihyun forgot to lock it behind him, which she apparently did seeing as the door swung up. Kyuhyun moaned as he picked up the bags once more and traveled to the kitchen before throwing them onto the island, wincing at the sound of glass clinking together.

“What in the actual fuck do you think you’re doing?!”

Kyuhyun jumped at the sound of Sungmin’s voice and frantically spun around, looking for the other.

“I’m sorry! I won’t throw groceries around again! Don’t hurt me Minnie!” Kyuhyun cried as he threw his arms over his head, preparing to be hit.

“Get away from me!”

Kyuhyun raised an eyebrow before peeking from behind his elbows and seeing Sungmin was no where around.

“I’m fucking going insane. Now I’m hearing Sungmin everywhere.”

“Stop!”

Kyuhyun jumped as a loud band sounded throughout the whole house and proceeded to run up the stairs.

“Min?!”

“Oh come on Oppa! Kyuhyun doesn’t have to know, we both know you like me more,” Kyuhyun’s eyebrows furrowed at the response.

Is that Jihyun?

Anger boiled through Kyuhyun and he was prepared to stomp his way into that room and rip her hair out for trying once again to steal his boyfriend.

“No. I don’t like you…at all. You’ve been playing this little game with your brother for who knows how long, torturing him by stealing every single love interest, but you’re not going to steal me away from him. Why? Because I love him. LOVE~! He’s smarter than you, he has a better personality, and he’s a hella lot sexier than you - Kyuhyun smirked and nodded in agreement - Cho Kyuhyun will always be the one for me and he will always be better than you."

Kyuhyun’s heart pounded in his chest as he wrapped his fingers around the door knob and pushed the door open. Two eyes moved to the door, one filled with momentary anger then utter love and the other in pure fear.

Kyuhyun ignored his younger twin as he slowly walked up to Sungmin and cupped his cheeks with his hands.

“Is that true?” Kyuhyun whispered, eyes glistening with adoration.

Sungmin giggled and nodded, looking up at the younger from underneath his eyelashes.

Kyuhyun swooped down and captured the others lips in a passionate lip-lock, forgetting all about his twin sister who was currently picking up her robe and high-tailing it out of there. Sungmin smiled against his lips before pressing harder into him, deepening the kiss.

Kyuhyun groaned as Sungmin tugged on his lower lip and peppering light kisses on face.

“I love you Sungmin, so much,” Kyuhyun whispered as he leaned down and pressed his lips against the others shoulder.

Sungmin sighed in bliss as Kyuhyun traveled across his shoulder and up his neck to his lips once again.

“I love you too,” the older murmured against his lips as he let himself be walked backwards until his back was pressed against the door.

Hands caressed each other’s bodies before slowly plucking clothes off one by one. By the time Sungmin was completely naked, Kyuhyun was left with his pants unbuttoned and Sungmin’s hand underneath, massaging the younger’s member.

Kyuhyun let his head fall forward against the others shoulder, hot breaths fanning across his skin. Sungmin traveled down his chest with his lips sliding across bare skin, stopping briefly to tug on his nipples with his teeth. He gave a tentative lick before continuing down, letting his tongue trail down the younger’s abdomen and dip into his navel. Now on his knees with Kyuhyun’s palms pressing against the wall, he eyed the trail of hair, lightly brushing it with his finger before licking a stripe up.

The younger groaned, letting his forehead hit the wall as his eyes watched Sungmin kneel between his legs, back flat against the wall. He lets his hands rest on the younger’s waist before dipping his fingers underneath the elastic band, pulling it back and letting it pop against Kyuhyun’s skin. Said man hissed in frustration as Sungmin teased him, winking up at him before pulling both the pants and the boxers down in one swift tug.

Kyuhyun’s member sprung against his stomach, leaving a dot of pre-cum right below his navel. Sungmin leaned his head forward, lapping up at the dot while simultaneously flicking his tongue against Kyuhyun’s slit. A gasp was heard above him, but he was more focused on gaining more of those breathless responses.

Sungmin wrapped his fingers around the younger’s shaft, creating a firm grip before pulling the member down and taking it into his mouth. Kyuhyun’s knees slightly buckled at the pleasure, but he was able to hold himself up. Sungmin’s mouth was damp, hot, and sucking him in. The older pulled back, running his tongue flat as he leaned back before moving back in.

Kyuhyun’s hips snapped forward, gagging Sungmin for a second before he pulls back and runs his fingers through the older’s hair in apology. Sungmin gave a reassuring smile before sliding back up and sneaking his tongue into Kyuhyun’s mouth. Kyuhyun suppressed a shudder at the taste of his own pre-cum on his tongue as his hands slid to either side of the older’s hips and tugged him closer.

“How do you want me to take you?” Kyuhyun asked as he kissed his way across Sungmin’s cheek to the tip of his ear, flicking his tongue against the lobe at the end of his sentence.

Sungmin mewled at the possibilities, but there was one prominent idea in his head at the moment.

“I want you to take me against the door and to make me scream. I want Jihyun to hear how much I belong to you,” Sungmin murmured against Kyuhyun’s neck as he peppered small kisses across his shoulder.

Kyuhyun couldn’t have been more in love with Sungmin at the moment.

Kyuhyun pulled away from the older to collect the lube from his shoe box in the closet before making his way back to find Sungmin slowly sliding his hand up and down his leaking shaft.

“Can’t wait for me babe?” Kyuhyun teased, a smirk pulling against his lips as he swatted away Sungmin’s hand.

“Having your cock so near me, but not in me is making me crazy,” Sungmin giggled before turning around and wiggling his butt at Kyuhyun.

Said man didn’t hesitate to slap the flawless masterpiece known as Sungmin’s ass. Sungmin knew Kyuhyun had a special fascination with his ass and would love to tease the younger by bending over whenever he could or running his hands up his backside as he looked at himself in the mirror - it would simply drive Kyuhyun crazy. Kyuhyun would’ve spent more time playing with the man’s ass, but he was nearing his end (of sanity).

“Shit Min, if you keep this up, I’m going to be finished before we even start,” Kyuhyun groaned against the older’s shoulder blade as his fingers lingered on his ass.

Sungmin sighed at the slight sensation before a groan slipped through his lips at the finger prodding his entrance, teasingly slipping in the tip before pulling out and circling.

“I’m gonna be done soon if you don’t hurry up and get in me,” Sungmin whined, pressing his face against the wall and butt against Kyuhyun.

Kyuhyun gave a small hump to tease before pushing the first finger in and quickly the second.

The younger’s pride swelled at every sound escaping the older as he scissored his entrance before curling the two fingers. Another finger joined and soon enough Kyuhyun deemed him ready for the real thing.

“God, you look so beautiful,” Kyuhyun chuckled against Sungmin’s cheek while slowly pushing in.

“Yes, because I look so beautiful with a cock in my ass,” Sungmin breathily laughed as he slowly adjusted.

“You do, but only with mine,” Kyuhyun grinned, wiggling his eyebrows when Sungmin looked back at him and rolled his eyes.

"Just shut up and fuck me.”

Not a second later, Kyuhyun pulled back and snapped his hips forward into Sungmin, slamming the older into the door. There wasn’t a doubt that Jihyun couldn’t hear them with the way Sungmin screamed, maybe even the neighbors.

“Shit, Kyu,” Sungmin moaned as each thrust resulted in him banging against the bedroom door, “I love the way you feel inside me, so big.”

Kyuhyun gritted his teeth; his hands griping onto Sungmin’s hips like his life depended on it.

The younger jerked at the sound of a high-pitched keening sound coming from his boyfriend after a particular thrust.

“No,” Sungmin cried, pushing himself against the younger, “do that again!”

Kyuhyun thrusted again and smirked when Sungmin keened once more.

“Mm, do you like that?” Kyuhyun teased, slowing down and starting to shallowly thrust.

Sungmin let out a sob of frustration, pushing himself back against Kyuhyun in attempt to hit that spot again.

“Do you Minnie?” Kyuhyun whispered near the older’s ear, nipping at the skin right beside his jaw while rolling his hips painstakingly slow.

Sungmin frantically nodded, eyes clenched shut and jaw slack as he panted, trying to breathe properly as wave after wave of pleasure hit him. Sungmin could feel the pressure build up in his lower abdomen and he knew Kyuhyun could tell.

“Cum for me Ming-ah, I want you to cum for me.”

With one last thrust, Sungmin shoots his load against the door with a whimper and Kyuhyun inside Sungmin with a grunt and a faint, throaty moan of Sungmin’s name.

Before Sungmin’s legs could fall out from under him, the younger snaked his arms around his waist and guided the older to the bed before the two of them lied down, Kyuhyun’s head propped against pillows with Sungmin between his legs, back to chest.

Sungmin twisted around in Kyuhyun’s arms and pressed a chaste kiss against Kyuhyun’s lips.

“You know I love you right? You and only you,” Sungmin whispered before placing his head against his bare, glistening chest and listening to the younger’s steady heartbeat.

“I know…I trust you. It’s Jihyun I don’t trust,” Kyuhyun scowled while unconsciously wrapping a stand of Sungmin’s hair around his finger over and over again.

“Maybe…she’s jealous? Not of you, but of me. Have you been paying much attention to her?”

Kyuhyun twisted his lips in thought. Had he been paying much attention to the younger twin? He thought so. He even felt that they spent more than enough time together. They shared a room for goodness sake!

“She needs her own boyfriend…or girlfriend. Whatever way she swings.”

Sungmin laughed incredulously before snuggling more into Kyuhyun’s arms.

“I love you Kyuhyun,” Sungmin murmured before drifting off to sleep.

“I love you too Sungmin…and no one will take you away from me.”
