          Su-ho has been having dark fantasies... s@xual ones about his boyfriend, Si-eun. It’s not like every other s@xual fantasy, it’s...different from what others may like, and Su-ho isn’t into polygamous relationships but he did want to see Si-eun have sex with another guy...maybe even a threesome.Don’t get him wrong, he loves Si-eun just the way he is but it’s just that he wants to see Si-eun get absolutely wrecked by another guy. He wants to know what they’re comfortable with and push Si-eun to his limits, but Su-ho hasn’t got the courage to confront him about it.But then again, it was all in his head. Su-ho couldn’t go a day thinking about it though, he got hard every time he thought about how pretty Si-eun would look...how wrecked he would be. He bought a vibrator a few weeks ago, along with metal handcuffs and a lacy blindfold– it doesn’t cover much but Si-eun would look pretty with it on– but he never used any of it on Si-eun, he doesn’t know if Si-eun is into that sort of stuff. Su-ho’s been hiding it from him but he’s bound to find out, right? “Su-ho, what’s this?” Si-eun walked into the living room with Su-ho’s opened laptop in his hand. Earlier Su-ho let Si-eun use his laptop to do his homework but Si-eun accidentally clicked the tab close, upon entering the history, he saw all the things Su-ho searched.Both their hearts were pounding as Si-eun stood in front of him. Softly biting his lip, Si-eun looked at Su-ho with worried eyes. “Si-eun...”“Do you want to see other people?” Su-ho stood up quickly and shook his head.“No, that’s...I–”“Su-ho–” Si-eun voice cracked, Su-ho shut the laptop and placed it on the coffee table before hugging Si-eun.“Please, it’s not like that. I love you so much, I would never think of seeing anyone else.” Su-ho murmured, kissing his head, he ran his fingers through Si-eun hair, kissing the top of his head. “Please believe me...”“Then why...?” Si-eun looked up at Su-ho, who wiped his face, Su-ho frowned then gave him a small smile.Holding Si-eun still as they sat on the couch. He couldn’t bring himself to look Si-eun in his eyes because he felt disgusted...but he briefly wondered how much did Si-eun see. “What did you see?”“Just the stuff about...dating site, that’s all, why?” Si-eun asked, frowning in a way that made Su-ho heart hurt.“Nothing, I’m not interested in anyone else, or am I trying to see anyone...I should have been honest with you.” He said, sighing, he looking down his hand. Not looking at Si-eun face, he closed his eyes to explain. “Ever since we got together, I’ve been imagining another person with us, I’ve been having fantasies about it...”“A threesome?”“N-no, more like...them f@ck@ng you, I can’t help it, it’s arousing to me and for months now I’ve been wanting to see you like that...getting– you’re– I don’t know, Si-eun.” Si-eun was genuinely confused, he just stared at Su-ho. “That’s if you want to...if you’re comfortable, of course.”Si-eun turned his head and slowly pulled his hands away, he doesn’t know how that will work...he was confused and somewhat disgusted. “Are you sure?”“I’ve been thinking about it for a long time but...only if you want to.” He whispered, Si-eun nodded a bit, he smiled.“I need to think...I can’t–”“No, you don’t have to do it, I only thought about!”“Su-ho, I want you to be happy and I saw all those things and I’m not gonna be comfortable having sex with someone in front of you, did you think about that?"“I asked...Seong-je about it already.” Su-ho said, cautiously, Si-eun glared at him. “He–”“Seong-je is our friend...”Su-ho sighed. “I know, Si-eun, but I thought you’ll be comfortable with him and...I kinda like him too, for you.”“Like him?” Si-eun, raising a brow, Su-ho nodded.“As a friend...I like him for you.” Su-ho move closer Si-eun but he physically recoils. “But if you don’t want to it’s okay and I’ll tell Seong-je no, I won’t bring it up again.”“Su-ho, I need to think.” Si-eun sighed, wiping his hand over his face again.•“Happy birthday,” Si-eun grinned as he placed Su-ho’s birthday cake on the table, he stood next to Su-ho as he blew out his candle. He touches Su-ho hair behind his ears, Su-ho smiled up at him before he leaned down and kissed Su-ho. It’s been a month since their talk, but that doesn’t mean Si-eun has forgotten about it, he has been thinking about it and since it is Su-ho birthday– it doesn’t sound bad as long as he doesn’t have to do it again. He vaguely wonders why Su-ho wanted it anyways, Su-ho always said he was enough but he just had fantasies that only Si-eun can fulfill.There was a knocking at the door, Su-ho groaned making Si-eun smile. “Let’s ignore it, maybe they’ll go away.” He whispered, Si-eun shook his head, smiling wider.“I think it’s your birthday gift,”“I told you you didn’t have to get me anything,” Si-eun almost pouts.“I think you’ll like this one.” He said, he leans up and kisses Su-ho before going over to the door, he looked through the peep hole before opening the door. There stood Seong-je in all black, he was wearing a black jacket, black sweat pants and black sneakers, he gave Si-eun a smile.
Seong-je hugged him. “Hi,”“Hey, where’s Su-ho?” Si-eun bit his lip before intertwining their fingers, he turned and they both walked in the direction of the kitchen. “Hey,” Seong-je waved at Su-ho, who looked stunned to see him.“Your gift!” Si-eun almost bouncing in front of them as he clasped his hands in front of him, Su-ho stared at them, he thinks he just fell in love all over again.“Are you sure about this?” Su-ho asks, cautiously.“Yes, I am.” Si-eun said, nodding, they both looked at Seong-je. Before leaving for the bedroom, Su-ho gives Si-eun a tall glass of water. “Drink this.”“Go on,” Seong-je urges, his hand petting the back of Si-eun’s head as he puts the glass to his lips. Su-ho and Seong-je glance at each other, sharing a secret smile. Si-eun finishes, giving him the glass back. “Come. Don’t pee,” He whispers in Si-eun’s ear.He gasps a little. Don’t pee?“It’s not what you think.” Seong-je smirks, holding his hand out to Si-eun.“Trust me.” Su-ho looks so sexy and genial. How can Si-eun resist?“Okay.” Si-eun places both his hands in either of their hands, because quite simply, he’d trust them with his life. What have they got planned? His heart starts pounding in anticipation.Su-ho leads them into the bedroom. Su-ho releases Si-eun hand, pulls his T-shirt over his head, and tosses it onto a chair. He steps out of his shorts in one graceful move. He grasps Si-eun’s chin, pulling slightly so that Si-eun stops biting his lip and Su-ho runs thumb along his lower lip.“That’s better.” He turns and strides over to the dresser that houses his clothes. He produces two pairs of metal handcuffs and a lacy eye mask from the bottom drawer.Handcuffs! Si-eun glances quickly and nervously at the bed. Where the hell is he going to attach those? He turns and gazes steadily at Si-eun, his eyes dark and luminous.“This can be painful. They can cut your skin if you pull too hard.” He holds up one pair. “But I really want to use them on you now.”Holy f@ck. Si-eun mouth goes dry.“Here.” He stalks gracefully forward and hands Seong-je a set. “Do you want to try them first?”They feel solid, the metal cold. Vaguely, Si-eun hopes he never has to wear a pair of them for real. Su-ho is watching him intently.“Where are the keys?” Si-eun voice wavering.He holds out his palm, revealing a small metallic key. “This does both sets. In fact, all sets.”How many sets does he have?He strokes Si-eun’s cheek with his index finger, trailing it down to his mouth. He leans in as if to kiss him. “Do you want to play?” He says, his voice low, and everything in Si-eun’s body heads south as desire unfurls deep in his belly.“Yes,” he breathes.He smiles. “Good.” He plants a feather light kiss on Si-eun’s forehead. “We’re going to need a safe word.”What?“Stop won’t be enough because you will probably say that, but you won’t mean it.” Seong-je explains.Si-eun’s heart starts pounding. Sh@t...can he back out now?“It’s not gonna hurt. But it will be intense. Really intense, because I am not going to let you move. Okay?” Seong-je says, Su-ho nods, somewhat reassuring Si-eun.This sounds so hot. Si-eun’s breathing is too loud. F@ck, he’s panting already. Thank heavens this is Su-ho, otherwise this would be embarrassing.Si-eun’s eyes flick to Seong-je. When did he undress?“Okay.” His voice is barely audible.Seong-je smiles. “Choose a word, Si-eun.”Oh...“A safe word,” Su-ho says softly.“Red?” Si-eun says, panting.“Red?” Seong-je says, amused.“Yes.”He grins as he leans back to gaze down at Si-eun. “Lift up your arms.”Si-eun doess, and Seong-je grasps the hem of his shirt, lifts it over his head, and tosses it on the floor. He holds out his hand, and Su-ho gives him the handcuffs.He places both sets on the bedside table along with the blindfold and yanks the quilt off the bed, letting it fall to the floor.“Turn around.” Si-eun turns. “You smell nice,” Seong-je mutters and tugs on Si-eun’s hair. He gathers it into one hand and yanks gently so Si-eun step back against him. Against his chest. Against his erection. Si-eun gasps, glancing at Su-ho who is silently watching as Seong-je pulls Si-eun’s head to one side and kisses his neck.“You’re very obedient,” He murmurs in Si-eun’s ear, sending delicious shivers through him.“Yes,” Su-ho almost whispers, agreeing with Seong-je.“Hmm. What are we going to do with that?” Si-eun breathes as Seong-je squeezes his chest, never breaking eye contact with Su-ho. Seong-je’s soft languid kisses are driving him wild. He grins against Si-eun’s neck, he straightens. Taking Si-eun’s hair, he tugs gently and leans down to his ear.Before Si-eun has time to react, Seong-je is moving suddenly, grabbing him by the waist, sits down on the bed, and yanks him across his knee so that Si-eun feel his erection pressed against his belly. He smacks Si-eun’s ass once, hard. With a swift movement Si-eun is on his back on the bed, and Seong-je gazing down at Si-eun, his eyes molten. Si-eun is going to combust.“Do you know how beautiful you are?” He trails his fingertips up Si-eun’s thigh so that he tingles...everywhere. Without taking his eyes off of Si-eun, he gets up from the bed and gathers both sets of handcuffs. He grasps Si-eun’s left leg and snaps one cuff around his ankle.Lifting his right leg, Seong-je repeats the process so Si-eun have a pair of handcuffs attached to each ankle.“Give me your hand,” He orders and Si-eun complies immediately.He blinks at Seong-je then draw up his legs so they are bent in front of him on the bed, putting his arms down. Seong-je reaches down, lifts his chin, and plants a soft, wet kiss on Si-eun’s lips before slipping the blindfold over his eyes. Si-eun can see nothing, all he can hear is his own rapid breathing and the sound of Su-ho and Seong-je.“What’s the safe word, Si-eun?”“Red.”“Good.” Taking Si-eun’s left hand, he snaps a cuff around his wrist then repeats the process with his right. Si-eun’s left hand is tied to his left ankle, his right hand to the right ankle. He cannot straighten his legs. Holy f@ck.“Now,” Seong-je breathes, “I’m going to f@ck you till you scream.”What? All the air leaves Si-eun’s body.The cuffs tighten as Si-eun pulls against them. Su-ho is right...they cut into his skin almost to the point of pain...this feels weird—being trussed up and helpless— Seong-je pulls his ankles apart, and he groans.He kisses Si-eun’s inner thigh, and Si-eun wants to squirm beneath him, but he can’t. He has no purchase to move his hips. His feet are flat against the bed. He cannot move. Holy sh@t.“You’re going to have to absorb all the pleasure, Si-eun. No moving,” Su-ho murmurs as Seong-je crawls up Si-eun’s body, kissing him. Si-eun is naked and at his mercy. He kisses his belly, nipping his navel with his teeth.Si-eun sighs. This is going to be tough...Si-eun had no idea. Seong-je traces soft kisses and little bites up to his chest.“Shh,” He soothes. “You are so beautiful, Si-eun.”Si-eun groans, frustrated. Normally he’d be grinding his hips against Su-ho, responding to his touch with a rhythm of his own like every other time Su-ho f@ck@d him, but he cannot move. Si-eun moans, pulling on his restraints.The metal bites into his skin. Si-eun cries out. But he really doesn’t care.“You’ve been driving me crazy,” Seong-je whispers. “So, I am going to drive you crazy.” He’s resting on Si-eun now, his weight on his elbows as he pushes his lubed fingers into Si-eun, and he turns his attention to Si-eun’s nipples. Biting, sucking, and rolling his nipples between his fingers and thumbs. He doesn’t stop. It’s maddening. His erection pushes against Si-eun’s.“Su-ho,” Si-eun begs and feeling Seong-je’s triumphant smile against his skin.“Do you want c@m this way?” He murmurs against Si-eun nipple, causing it to harden some more. His fingers curling inside of Si-eun. “I can...” He suckles Si-eun hard, pleasure lancing from his chest directly to his groin. Si-eun pulls helplessly on the cuffs, swamped by the sensation.“Yes,” Si-eun whimpers.“Oh, baby, but that would be too easy.”“Please.”“Shh.” His teeth scrape Si-eun’s chin as he trails his lips to his mouth, and Si-eun gasps.He kisses Si-eun. His skilled tongue invades his mouth, tasting, exploring, dominating, but Si-eun’s tongue meets his challenge, writhing against his. He tastes of peppermint and Seong-je, and he smells so good. He grasps Si-eun’s chin, holding his head in place.“Still. I want you still,” He whispers against Si-eun’s mouth.“I want to see you, Su-ho.”“Oh no, Si-eun. You’ll feel more this way.” Su-ho calls out to him. And agonizingly slowly Seong-je flexes his hips and pushes partway into Si-eun. He would normally tilt hid pelvis up to meet Su-ho but he can’t move. Seong-je withdraws.“Seong-je, please.”“Again?” He teases, his voice hoarse.“Come on,”He pushes fractionally into Si-eun again then withdraws while kissing him, his fingers tugging at Si-eun’s nipple. It’s pleasure overload.“No!”“Do you want me, Si-eun?”“Yes,” Si-eun practically begs.“Tell me,” He murmurs, his breathing harsh, and he teases once more—in...and out.“I want you,” Si-eun whimpers, licking his lips. “Please.”Si-eun hears Seong-je’s soft sigh against his ear. He rears up and slams into Si-eun, who screams, tilting his head back, pulling on the restraints as Seong-je hits his prostate dead on, and he’s all sensation, everywhere—a sweet, sweet agony, and Si-eun cannot move. He stills then circles his hips, and the motion radiates deep inside Si-eun.“Look at you, such a f@ck@ng wh@r@.”“Seong-je, stop...” Si-eun moans softly.He circles deep inside Si-eun again, ignoring his plea, easing out slowly and then slamming into him again.“Say you’re a wh@r@,” He hisses, and Si-eun’s vaguely aware that it’s through gritted teeth.He cries out in an incoherent wail...this is too much.“Say it.”“Seong-je...”“Say it, Si-eun.” Su-ho pants, breathlessly.Seong-je slams into Si-eun again, thrusting so deep, and he’s building...the feeling is so intense—it swamps Si-eun, spiralling out from deep within his belly, to each limb, to each biting metal restraint.“I’m a wh@r@,” he cries out. “Please, Su-ho.”Seong-je and Su-ho groan loudly in unison and Seong-je thrusts deep, again and again, over and over, and Si-eun lost, trying to absorb the pleasure. It’s mind-blowing...body blowing...he longs to straighten his legs, to control his imminent @rg@sm, but he can’t...he’s helpless. He’s Su-ho’s, he’s Seong-je’s, just theirs, to do with as they will...tears spring to his eyes. This is too intense. Si-eun can’t stop him. He doesn’t want to stop him...he wants Su-ho...he wants...“That’s it,” Su-ho moans. “Feel it.”Sieun c@m on himself and Seong-je, again and again, squeezing round and round Seong-je’s c@ck, moaning loudly as his @rg@sm rips him apart, scorching through him like a wildfire, consuming everything. He’s wrung ragged, tears streaming down his face—his body left pulsing and shaking.And he’s aware that Seong-je kneels, still inside him, pulling him upright onto his lap. Seong-je clutches his head with one hand and his back with another, and he c@ms violently inside Si-eun while his insides continue to tremble with aftershocks.It’s draining, it’s exhausting, it’s hell...it’s heaven. It’s hedonism gone wild.Su-ho joins them on the bed, removing the cuffs before he tears off the blindfold and kisses Si-eun. He kisses his eyes, his nose, and his cheeks. He kisses away the tears, clutching Si-eun’s face in between his hands. Seong-je lays Si-eun on the bed, pulling out, Si-eun is barely recovered as Su-ho is flipping him over, pulling him up by his waist so he’s arched on the bed in front of him.“Ready?” He whispers.“Yes,” Si-eun mutters quietly, unsure of what he’s agreeing to, his mouth is dry. Su-ho runs another finger down to his ass and slips it inside Si-eun. F@ck, it’s his thumb. His other hand goes around and takes Si-eun’s c@ck in his hand and his fingers gently tease the tip. Si-eun moans...it feels...good. Despite the fact he’s already tired. Su-ho gently, while his fingers and thumb work their magic, pushes a cold plug slowly into Si-eun.“Su-ho,” Si-eun groans loudly at the unfamiliar sensation, his muscles protesting at the intrusion. Su-ho circles his thumb inside Si-eun and pushes the plug harder, and it slips in easily, and Si-eun doesn’t know if it’s because he was just f@ck@d by Seong-je or if he’s so turned on again, but his body seems to accept it. It’s heavy...and strange.“Tell me if I’m too rough. Understand?”“Yes,” Si-eun whispers again, and he slams into Si-eun and pulls Si-eun onto him at the same time, jolting the plug forward, deeper...“F@ck!” Si-eun cries out.Su-ho stills, his breathing harsher and Si-eun panting matches his. Si-eun tries to assimilate all the sensations: the delicious fullness of having both Su-ho and the b@tt plug inside him, the tantalizing feeling that he’s doing something forbidden, the erotic pleasure that spirals outward from deep within him. Su-ho pulls gently on the plug.Si-eun moans, and he hears Su-ho sharp intake of breath—a gasp of pure, unadulterated pleasure. It heats Si-eun’s blood. “Again?” Su-ho whispers.“Yes.”“Stay down,” He orders. He eases out of Si-eun and rams into him again.Si-eun wanted this. “Yes,” he hissed.And Su-ho picks up the pace, his breathing more laboured, matching Si-eun’s own as Su-ho thrashes into him.“Si-eun,” He gasps. He moves one of his hands from Si-eun’s hips and twists the plug again; tugging it slowly, pulling it out and pushing it back in. The feeling is indescribable, and Si-eun think he’s going to pass out on the bed. Su-ho never misses a beat as he takes Si-eun, again and again, moving strong and hard inside him, and Si-eun insides tightening and quivering.“Oh, f@ck, Su-ho.” Si-eun moans. This is going to rip him apart.“Yes,” Su-ho hisses.“Please,” Si-eun begs him and he doesn’t know what for—to stop, to never stop, to twist the plug again. Si-eun’s insides tightening around Su-ho’s c@ck and the plug.“That’s right,” He breathes, and he slaps Si-eun hard on his right cheek. “I want you to c@m, Si-eun, c@m for me,” he hits Si-eun again, harder, and Si-eun c@ms—again and again, and Su-ho gently pulls the plug out.Seong-je helps Si-eun to his hands before kissing him. “C@m for us, baby.” Si-eun’s face scrunches up in that way, his mouth open but no sound comes out, Seong-je kisses him again, encouraging him. “That’s it.”“Oh, f@ck,” Si-eun groans his head dropping, Seong-je continues to encourage him, Si-eun’s hands grip the pillow and duvet nearest as his body convulses. Su-ho press their bodies together, holding his hips tightly, which as definitely going to leave a mark on Si-eun’s body, as Seong-je holds Si-eun’s red lined wrists and Su-ho groans loudly on Sieun’s back, holding him still. Su-ho pulls out, he lies next to Si-eun, who collapsed moments before, Seong-je on the opposite side of him. Si-eun rolls over and looks at Su-ho. “Was I good?”“You did so good, you were amazing.” Su-ho praised, Si-eun sighed softly, Su-ho leans down and kisses him. Pulling away, he gave Su-ho a small smile before turning to Seong-je and kissing him as well. Longer than expected, Si-eun pulled away, placing his both his hands on either of the men in front of him heads, Su-ho hesitated for a moment.“Kiss him...” Si-eun urges, running his tongue over his top lip, Su-ho leans in and kisses Seong-je, short and hesitant. “More,”Seong-je laughs a little, putting his hand over Si-eun’s hand behind Su-ho’s head, pulling him in, kissing him roughly. Su-ho returned the energy, after all he was doing it for Si-eun, who couldn’t take his eyes off of them, his pupils dilating more than they already are. Seong-je lets out a grunt, Su-ho pulls away, smiling at Si-eun, who looks like he’s enjoying himself a bit too much. “Next time, we should try double penetration.”Si-eun’s eyes widened, he glances at Seong-je, who’s snickering to himself but silently agreeing. “You mean...”“He means, the both of us, at the same time, yes.”“I don’t know if I can...”“I think you can.”Si-eun shakes his head. “Su-ho,”“You’ll just need...”“Lots of prep,” Seong-je agrees once more, his eyes flicks to Su-ho, who’s already looking at him, a wicked gleam in his eyes.Si-eun snorts, his expression changes. “You’re joking...”“No. Not at all.” Si-eun doesn’t know if they’re joking or not. But he hopes it’s the latter, he doesn’t know if he’s up for it.'
