NOTE: don’t like, don’t read.

A lot of people find your relationship with your stepbrother cute. How could they not? He’s always so doting and protective like a real brother would be. In spite of being only slightly older, Heeseung takes on a very important role in your life. He constantly goes out of his way to take care of you, making sure you have anything you could possibly need.

Heeseung’s girlfriend never thought too much about the relationship between you two. It was natural that he took the naive college freshman under his wing and constantly had you by his side. Mina found it endearing, actually. The way he worried about you like a mother hen who wasn’t ready for her young chick to go into the world alone is adorable and a good sign. After dating so many inconsiderate losers, she thinks she’s finally chosen the right guy.

But somewhere along the way, Mina starts to grow tired of it. Time has gone by, and you’re no longer a naive freshman who can’t get around without her boyfriend’s help. Of course family is important, but it’s not like you’re entirely helpless. And yet, that’s exactly the way Heeseung acts. He’s always ready to drop everything when you need him. On several humiliating occasions, he’s even left her half naked on his bed just to go to you because you bought something you couldn’t figure out how to put together, or because you wanted to hang out with him.

It’s hard for Mina to admit that she’s a little jealous. Especially because it all seems so ridiculous. There’s no way her boyfriend actually wants you like that. But as time goes on, she thinks that maybe she’s not all that crazy. Especially with the affectionate way her boyfriend looks at you. Despite all this, Mina doesn’t say anything. At least, not until Heeseung starts to bring you along to what were meant to be dates.

“Babe, why do you keep bringing your stepsister? i thought we were going on a date?” It’s hard for her to not sound bitter and annoyed.

“Her roommate is going to visit her parents, and I don’t want Y/N to be alone.” His tone is kind and gentle like always, but it’s also firm and leaves no room for arguments.

What’s worse is that Mina can’t bring herself to hate or blame you. In a way, she understands why her boyfriend is always so concerned about you. You’re so nice and trusting that it would be way too easy for someone to take advantage of that. There’s also the fact that you’ve been more than willing to let them have some alone time, but Heeseung never lets you leave.

It’s all so strange and frustrating that Mina feels like she has to take matters into her own hands. So she does.

The key to Heeseung letting you go is getting you a boyfriend—or at least getting you to start dating. It’s easy enough to find a guy who’s interested in you. That’s never been a problem for you, and all it takes is her showing your picture to the cute guy in her communications class for her plan to fall into place. As luck would have it, you’re also into meeting the guy and going out with him.

Little did Mina know, setting you up with him would be a mistake that would cost her everything.

On the night you’re meant to meet up with her classmate, Mina excitedly goes to her boyfriend’s apartment. It’s been a long time since she got to be alone with Heeseung, and she was going to make the most of it.

She’s dressed in tiny tank top and a cute little skirt that Heeseung loves—it barely hides the lingerie she’s wearing underneath. Mina quietly lets herself into her boyfriend’s apartment using her spare key. Quietly, she tiptoes to his room only to find the door wide open. What she doesn’t expect is to find you sitting on his the edge of bed while Heeseung kneels in front of you.

Mina feels like a bucket of cold water has been dumped on her as his pretty hands rub your soft thighs. You look incredible, clad in a cute little dress with your makeup and hair done to perfection. It’s a mistake for Mina to keep watching, but she can’t find her voice at the moment.

“Seungie, what’s wrong?”

God, Mina hates that you call him that. Mostly because she can tell how much Heeseung likes it.

“Why didn’t you tell me you were going out to meet some guy?” Heeseung sounds almost venomous, but it’s like you don’t hear it. “Who is he? How’d you meet him?”

You tilt your head, pretty lips pulled down in a confused frown. “Didn’t Mina tell you? She set me up with a guy from her class. He’s really cute!”

A chill goes down Mina’s spine. She can see Heeseung’s back tense when you tell him how your date came to be. The air feels almost murderous as he gently squeezes your thighs.

It kills Heeseung that he was almost too late in stopping you from meeting some strange guy in the pretty little dress you have on. He softly rubs your thighs, eyes simmering with anger and desire he doesn’t care to hide. Not anymore.

“Oh, angel.” Your stepbrother murmurs, hands slowly trailing up to your thighs. “You know you’re my favorite girl, right?”

An unsuspecting smile graces your lips. “Yeah. And you’re my favorite guy.”

Heeseung hums in satisfaction as his fingers ghost the edges of your dress. He watches your eyebrows furrow, but you don’t say anything. As always, you have blind trust in your stepbrother. That’s all the indication he needs to get up and push you down on his bed. Heeseung hovers over you, loving how you’re staring up at him with sparkling, wide eyes. He swoops down to capture your lips in a searing kiss.

Your heart is racing in your chest as Heeseung forces his tongue into your mouth. Despite the initial shock, you quickly melt into the kiss. He swallows your moans, pulling you closer as he deepens the messy kiss. You mewl into his mouth, carding your fingers through his hair with desire you had never realized you had for him.

Meanwhile, Mina can only watch as her boyfriend kisses you with a passion that he clearly never felt for her. It feels like her heart is ripping in half as Heeseung begins to undress you. Tears well up in her eyes when he groans at the sight of the lingerie adorning your body. Mina can see how hard he is from where she’s standing, and the desire in his eyes is very different from the way he looks at her.

“Can’t believe you got all pretty for some other boy.” Heeseung spits as he starts to undress. “Were planning on letting him fuck you?”

You shake your head and go to speak, but you can’t when Heeseung roughly pulls off your lingerie then his own underwear. His cock is thick and big, possibly the biggest you’ve ever seen. It’s twitching and leaking as he looks at you with his dark eyes.

“W-We shouldn’t be doing this.” You whine as Heeseung shoves your thighs to your stomach and licks a broad stripe up your wet pussy.

Your stepbrother groans at your sweet taste, thrusting his tongue into your dripping hole. He laps up the juices leaking out of your slit, circling his tongue on your clit for good measure. The noise you let out is downright pornographic and pure music to Heeseung’s ears.

“Seungie!” You keen as you spread your legs and tangle your hands in his messy hair. “I– Fuck!”

Heeseung pulls back with a wet slurp to spread your cunt open with his big hands. “God. You have the prettiest pussy I’ve ever seen, angel. Just had to taste it.”

Each one of his words is like a dagger to Mina’s heart and confidence. Wet tears trickle down her face, but she doesn’t say anything as you pull on her boyfriend’s hair. Heeseung only moans and dives back into your slick cunt. He greedily laps up everything that drips out of you, sucking and kissing your clit.

“We shouldn’t be doing this, Hee.” You repeat through a needy mewl, making no attempt to stop him. In fact, you buck your pussy into his mouth as he sucks on your sensitive bud.

“Shh, angel.” Heeseung shushes as he flicks his tongue across your swollen bud. “Just relax and let me eat you out. Been wanting to do this for so long.”

Mina swallows thickly, the hurt slowly being replaced by something else. Her eyes grow bigger when she realizes which feeling is taking over. She shifts slightly, feeling a familiar wetness begin to pool in her panties. Mina feels sick that the sight of her boyfriend cheating on her can turn her on, and she thinks that she should leave right now and never return.

But she stays.

Mina licks her lips and continues to watch. Even she can’t help but think how hot you look, whimpering and writhing as Heeseung pushes your thighs apart so he can bury his face deeper in your pussy. He flicks his tongue, slowly descending until he’s lapping at your hole, slowly fucking the wet muscle in and out. Your eyes roll back as your stepbrother eats your pussy like it’s the best thing he’s ever tasted.

The sounds coming from your pussy and the way Heeseung messily eats you out has Mina’s own cunt clenching with need. She can feel her underwear start to stick to her cunt as she watches her boyfriend lap up your arousal like a starved man. Mina bites her lip, feeling sick and twisted for being turned on by your pretty moans.

Heeseung suddenly pulls away, but not before he slaps your thigh playfully. He goes to lay on his back all while wearing a filthy smirk. “Sit on my face.”

You bite your lip as a hot flash of arousal pulses through your body. Both your and Mina’s cunts throb at the suggestion. Heeseung sees your hesitation, but doesn’t back down.

“C’mon, baby. Be a good little stepsister and ride my fucking face.” He growls out with dark eyes.

With your pussy dripping, you crawl over to him and kneel over his face. Mina watches with heated eyes as you slowly lower your cunt on her boyfriend’s face. The heat in her stomach grows when she hears Heeseung groan in satisfaction.

“That’s it. I want your pretty pussy suffocating me.”

With that, your stepbrother grabs your hips and pulls your cunt down onto his face with a groan. Mewling quietly, you rub your cunt all over his mouth. Every time he moans or grunts, it sends little vibrations through your pussy. The delicious feeling has you grinding down on his tongue as you chase that feeling. Heeseung eagerly fucks his wet muscle into your hot cunt, already addicted to your sweet taste.

Mina swallows thickly when he sees Heeseung thrusting into the air as he eats you out. His cock is leaking and throbbing with need. Fuck. How she’d like to go and lick all that up, to have him fuck her mouth as he fucks you with his tongue. Mina rubs her thighs to soothe the growing ache in her pussy as she watches you ride Heeseung’s face.

Your eyes roll back when your stepbrother slaps your ass. A loud squeal spills from your lips as Heeseung keeps fucking his tongue up into your cunt. He grabs your ass and kneads it roughly. With one last groan and flick of his tongue, he sits up and takes you with him. The effortless display of strength turns both women on, one containing her moan while the other cries out as she’s pressed back into the mattress.

“Such a sweet little cunt.” Heeseung moans as he buries his face back into your dripping cunt. “Shit, Y/N. You’re fucking soaked down here.”

“Heeseung!” You cry out as he pries your thighs further apart. Your stepbrother shakes his head to grind his tongue against your sensitive cunt.

“Fuck, you have the hottest little pussy.” Heeseung lifts his head with a groan, lips shiny with your arousal. “Missed eating some good pussy. It’s been so long.”

Mina feels pathetic that her cunt throbs at his degrading words. She bites her lip, hands trailing up her thigh and to her soaked underwear. It’s so filthy and humiliating, but the ache in her pussy is getting to be too much. She slowly rubs circles on her covered cunt as she keeps watching her boyfriend cheat on her.

“Fuck, Seungie.” You mewl desperately. “S-Shouldn’t like having your face buried in my cunt.”

Heeseung smirks into your wetness. He gently circles his tongue on your clit, kissing it tenderly before he gently starts to nip at it with his teeth. Mina shoves her panties aside when you moan out in pleasure. Now she’s furiously rubbing at her bare pussy, wanting to see you cum on her boyfriend’s face.

“But you do, baby. You like me fucking you with my tongue, and I fucking love eating this sweet little pussy.”

Your hips buck up at the words, grinding your cunt against his mouth as you moan for him. Juices drip out of you lewdly, leaking down to your ass and onto Heeseung’s sheets. Your head is swimming with pleasure, and you have to remember that this is all so very wrong.

“You like that?” Heeseung teases you, loving how you’ve turned into putty in his hands. “Answer me, Y/N. Do you like your stepbrother telling you how much he loves tasting your juicy cunt?”

Your back arches when Heeseung sucks your puffy bud into his mouth. “God—yes! Feels so fucking good, Hee! Love having your mouth on my pussy.”

Heeseung growls, the vibrations making your cunt throb as he sucks and licks your swollen clit. Eager to have you cum on his tongue, he slips two fingers into your fluttering hole. Mina follows in suit, unable to take her eyes off the erotic sight of you getting ate out and fingered. Fuck. This was better than any porn she had ever watched. Her hand is dripping with her own arousal, and she can’t even feel disgusted anymore that she’s so turned on by the entire situation.

“Mmmh, shit, Hee.” You whine as the tips of his fingers brush against the gummy spot inside you. “You’re gonna make me cum.”

“Do it, baby. Cream all over my tongue.” He purrs in delight. “Be a good girl and cum for me.”

Heeseung flattens his tongue on your clit while his fingers grind into the spongy spot in your cunt. Your back arches off the bed, orgasm whiting out your thoughts as you cum around his long fingers.

Mina has to cover her mouth as Heeseung moans along with you. By now she’s shoved her fingers into her sopping pussy, the squelching sound is drowned out from the sounds coming from your own pussy. The filthy sight is driving her wild, and she’s so delirious with arousal that she wishes Heeseung would just fuck you already.

“You’re amazing, angel.” Your stepbrother praises with his fingers still buried knuckle deep in your pussy as he softly strokes your velvety walls. “So soft and wet. It makes me want to shove my dick into your tight little hole.”

Heeseung slowly pulls his fingers out of you, and you can only watched with a lidded gaze as he moves his body between your thighs. His cock is twitching and leaking as he grabs the base. He smacks his cock down on your slippery pussy, dragging his drooling tip up and down your slit slowly. Mina has to press her hand into her mouth harder to stifle her filthy moans. The sight of her boyfriend pressing his drooling cockhead into your soaking pussy is so hot she might just cum all over her fingers.

“S-Seungie—fuck. We shouldn’t.” You whimper as he leans forward and braces his arms by your head.

You and Mina both know you don’t really mean your words. It’s clear that you want your stepbrother to split you open on his big cock. That becomes obvious when you don’t try to stop him as he shoves his cock into your pussy until he bottoms out completely, balls pressing against your ass. Shuddering with pleasure, you scratch your nails up his arms as you sink into the bed.

“Pretty pussy was meant to take my cock.” Heeseung growls, already drunk on the feeling of your cunt wrapped around his dick. “Fuck. I know it’s wrong, baby, but I just couldn’t help myself. Your hot little cunt was just begging for my dick. Doesn’t it feel all nice and full having your pussy stuffed with your stepbrother’s big cock?"

Mina starts fucking herself harder when you nod desperately. Your hands go to tangle in his hair as you grind your hips up to meet his thrusts. “Yes! Fuck! Love my stepbrother’s cock stretching me open! Feels so fucking good, Hee!”

Mina knows better than anyone how good you must feel. Although, she imagines you feel must better than she ever did because from the way Heeseung’s fucking you, she can tell he’s doing it with much more enthusiasm and passion. Even his moans are more guttural and full of more pleasure than she’d ever heard. They’re deep as he pulls out until just his tip is spearing you open. Then, he pushes forward, thrusting his cock deep into your fluttering walls.

“That’s it. Tell me how good it feels.” Heeseung leans down, lips brushing against yours. “Don’t be shy, angel. Let me know how much you like this cock fucking you.”

You gasp wantonly and pull him down further to press your lips together. He groans and licks into your mouth easily, tongue slipping past your lips as his cock thrusts deep into your hot, wet cunt. Your hips buck up to meet his, loving how his dick rams into your sweet spot over and over until your sight is painted with pretty little stars.

“Fucking love it, Hee.” You moan between sloppy kisses. “God—I love your cock!”

The coil in Mina’s stomach is close to snapping. By now, her juices are dripping down to her wrist. Luckily, the lewd squelching and sound of skin slapping together drown out any noise she’s making. Heeseung is fucking you so hard and good that she can smell the musky scent of sex from where she’s standing. The erotic aroma turns her on even more, pussy clamping down on her fingers in desperate need of release.

“Tight little pussy feels so good.” Heeseung moans out between the quick pecks he’s giving you. “God, I love you, Y/N. So fucking much.”

Your heart races as Mina’s breaks all over again. It hurts, but somehow that just turns her on even more. She keeps fingering herself as tears pool in her eyes.

With a low moan, your pussy clamps down on Heeseung’s dick tightly as you go to eagerly kiss him. A soft I love you, too goes unnoticed by Mina, but not by your stepbrother. He groans into your mouth, cock throbbing inside you.

“Mmmh.” Heeseung hums against your lips before he trails wet kisses down your neck. “I love my gorgeous girl. That’s why this feels so good. Even your tight little pussy knows how much I love you.”

His gorgeous girl? Mina thinks deliriously, orgasm dangerously close. It’s something he never referred to her as.

You cry out loudly when Heeseung bites your neck and sucks the skin into his mouth. His hips rock against yours, balls smacking against your ass as his pelvis grinds down on your swollen clit.

“Seungie!” You whine in ecstasy. “I’m getting close.”

Your stepbrother doesn’t let up. In fact, his thrusts seem to get faster and rougher. His cock pistons in and out of your cunt, creating sloppy wet sounds as you get even wetter. His eyes are dark as he pulls back to look at you, all pretty squirming and trembling on his cock.

“Cum for me, baby. Cover my cock with your sweet cream so I can fill you up.” Heeseung pants. “Cum on my cock, angel.”

His teeth sink into your neck again, and it pushes you over the edge. Your hot cunt throbs as you squeeze down on his cock. Somehow your pussy only gets tighter and tighter as you get fucked through your orgasm. You tighten your legs around his waist until he can barely pull out, rutting his cock in short shallow thrusts as your climax starts to taper off.

“So fucking tight.” Heeseung hisses by your ear. “Shit, baby. Get ready. I’m about to creampie your cute little pussy. Fuck, fuck, fuck!”

With a strangled grunt, he buries his cock to the hilt and shoots his load deep inside your fluttering walls while your pussy softly milks him for every drop of his hot cum. Mina reaches her own climax when she sees her boyfriend cumming inside you. She has to stifle her moans as she trembles and shakes outside the room that’s filled with the smell and sounds of hot sex.

“You’re taking it so well, angel.” Heeseung kisses your jaw tenderly as his fat tip spurts rope after rope of his thick cum into your clenching heat. “Milking my cock like I knew you would.”

He grinds his hips down, cock pulsing as he finishes stuffing you full of his hot, sticky load. Your stepbrother fucks his cum inside a bit more before reluctantly pulling out. Heeseung’s cock throbs as he watches his seed drip from your messy pussy.

He licks his lips, heated gaze never leaving your body. “Let’s do it again.”

You don’t try to protest as your manhandles into a different position. Mina is still coming down from her high when she realizes her boyfriend is still hard and about to fuck you again. She knows she shouldn’t feel excited or aroused by the fact, but she does. Especially when your face is shoved into one of Heeseung’s pillows just before his big cock rails back into your needy pussy.

Heeseung starts fucking you so hard his headboard slams into the wall repeatedly. The harsh sound pairs well with the plop plop plop sound coming from your cunt.

“God, Y/N. You’re so fucking good for me.” Heeseung groans when you clench down on him.

You moan loudly, bouncing yourself back on his cock. “Fu-Fuck, Seungie. This is wrong. We s-shouldn’t be doing this.”

“I know.” Your stepbrother smacks your ass, not sounding the least bit remorseful. “It’s so dirty baby, but I couldn’t help myself. Had to get my dick wet using your pretty little pussy.”

“Mmmh!” You whine out mindlessly, face turned to the side with your ass raised in the air for Heeseung to fuck deeper into your wet hole. “Feels so fucking good!”

“Yeah, it does.” Heeseung’s laugh sounds almost mean as he speeds up his thrusts to fuck his cock harder into your sopping cunt. “Your cute little pussy is the best I’ve ever had.”

His words shouldn’t please you as much as they do, but those lewd words turn you on so much that you can’t stop your cunt from tightening around him as he keeps spearing into you like an animal in heat. They also shouldn’t turn on Heeseung’s girlfriend but that’s exactly what they do. She isn’t angry, only extremely aroused as your ass bounces back on your stepbrother’s pelvis.

“Fuck!” Heeseung groans, fucking his cock right into your g-spot. “You’re so fucking hot, angel.”

You are. So hot that Mina finds herself wishing she could eat Heeseung’s cum out of your pretty cunt. She just knows you taste good, and mixed with her boyfriend she’s sure you must taste even better.

“Seungie, please!” You cry out, dizzy with arousal.

“Shit.” He growls, slipping a hand underneath your hips to rub fast circles on your clit. “Gonna make you cream on my cock again.”

“Heeseung!” You squeal as he picks up his pace, ramming into your squelching pussy as he rubs soft circles into your swollen clit.

Your stepbrother shoves his cock deep into your cunt and grinds, making you squirm and whine as his dick rubs against the spongy spot in your pussy. Your hands twist in the sheets. He flicks and pinches your puffy clit. God, do you look good, and so does Heeseung. Mina is groping one of her tits while the other hand goes to play with her pussy again. Briefly, she thinks she wouldn’t mind having a video of you two fucking so she can watch it over and over again.

“Hee, I’m gonna cum.” You moan against the pillow.

“Do it, baby.” He encourages you, free hand coming down to slap your ass hard. “Cum all over my cock. Want to feel your hot cunt squeeze me.”

It’s not long before your orgasm hits. You’re screaming into your pillow as your cream coats Heeseung’s big cock. Your pussy clamps rhythmically around his dick. Mina can’t see you, but with the way your toes are curling she can tell your eyes are rolling to the back of your head in pure ecstasy.

“Oh, baby. You feel so fucking good.” Heeseung praises you. His hands move to slap your ass again, making you squeal and tighten again. “Fucking work your little pussy on my cock. Fuck. Need to fill you up again.”

“Want you to stuff me full.” You whine back at him, pussy fluttering at the thought of Heeseung’s cum filling your cunt again.

“Yeah?” Your stepbrother laughs, sounding way too delighted. “Want me to creampie your hot little cunt again?”

“Please!” You whine as Heeseung’s fingers slide over your hip to start working soft circles into your clit again. You writhe back on him, feeling yourself get even wetter at the filthy thought of him shooting his hot load inside you.

“Cum inside me, Hee.” You pant, mewling when his fingers rub your clit even faster. “Want it so bad. Want to feel it.”

“Oh, fuck.” Heeseung groans, hips snapping hard against your ass when he feels how tight you’ve gotten. “You ready, baby? Fucking take it. Take your stepbrother’s cum in your needy little cunt.”

You moan loudly when you feel his hot cum filling your pussy, stuffing you so full it drips out around his cock. Heeseung ruts his spent cock into your sloppy pussy as he pinches your clit, watching as your back arches as a fourth orgasm sweeps through you. You lazily fuck your cunt back into him, loving the feeling of his cum dripping out of you and coating your thighs.

Heeseung pulls out of your warm cunt with a low groan. He’s quick to pull you against his chest and lays you down with him. His face is buried in your hair, eyes closed in bliss as you both try to catch your breaths. You feel his smile in your hair as he cuddles you and murmurs sweet praises against your temple.

Through your drooping eyes, you catch sight of Mina. Her eyes widen when you two make eye contact. You can’t hide your smirk when you see that she was masturbating to the sight of Heeseung fucking you raw. Instead of saying anything, you give her a seductive wink. Mina clenches around her fingers because the wink is full of understanding and promises.

It’s clear that Heeseung was never hers, but maybe you wouldn’t mind sharing.
