Seokmin clicks his tongue, this time slightly irritated, but it’s not exactly the type of reaction you’re used to getting from him. It’s lacking his usual energy.“So, does it mean that you would like to have one with me and another man?” he asks then, sounding surprisingly unsure as he absent-mindedly plays with the rings adorning his long fingers.It’s been ages since you heard that kind of tone in his voice, so you put your phone aside and turn towards him.“Depends. You know that I wouldn’t have sex with just anyone.”Seokmin nods slowly, his expression earnest as he patiently waits for you to continue.“I believe that there’s someone you already have in mind, otherwise you wouldn’t have asked me about it. So, who is it?”He smiles hearing your words, feeling pleased that you know him so well. His soft smile turns into a wistful one as he leans back against the sofa with a sigh.“Mingyu likes you, I think,” he carefully states, observing your reaction.“You think,” you repeat, rising a brow at him, not sure how to respond.“Well, no, I’ve chosen my words wrongly: I don’t just think that, I know that. The way he stares at you, the way he speaks about you – it all betrayed him quite a long time ago,” Seokmin quietly chuckles, ruffling his hair.“That unsure yet hopeful way of behaving around someone you’re interested in, you know? I used to act like that too, before I learned that you feel the same.”“But it’s not the case with Mingyu,” you say, knitting your brows slightly.“Yeah, I know.”“And you still want me to have sex with him?”“Well, it’s not exactly that I want you to have sex with him alone. Do you remember that conversation we had a few months ago about the possibility of someone from the outside joining us in the bed?”It takes you a moment to recall said conversation, but when you do, the realization comes to you immediately.“Back then, you said that you’d be interested in observing me having sex with another man, right?” you ask to confirm your assumptions.Seokmin nods as he leans forward, placing his elbows firmly on his knees.“Yes, I’d like to try that. Of course, your consent is an absolute priority – one word from you, and I’ll never speak about it again. However, if you were to agree, I’d rather see you with someone I know, someone I can put my trust into, rather than some stranger.”You nod, understanding where he’s coming from.“Also, I’d prefer to slightly modify my previous request: I don’t want to observe any more. Or rather, I’d prefer to not stay away for a whole time.”“Thus a threesome,” you muse, resting your chin on the palm of your hand.You’d have to think it over, of course, but his proposition definitely piqued your interest. There’s, however, one thing that niggles you.“For the starters, you should know that I’m not opposed to this idea. In fact, I find it highly arousing, however, would that be truly fine if he has feelings for me?”“It’ll be up to him to decide.”You turn your head towards him, not even trying to hide the surprise in your voice.“So you didn’t talk it through with him yet?”Seokmin shakes his head vigorously.“Like I said: your consent is my priority. Only if you agree first, I’m going to ask him about it.”“Sure,” you hum, already going over the proposal.“You know, I understand what you meant by saying that you’d feel uncomfortable if I were to have sex with a stranger. Even thinking about doing it with Mingyu feels different.”“Why?”“I guess I trust him. I can’t even imagine him hurting me, no matter the way. But there’s also something else.”You turn your body towards him before touching his cheek gently, the tips of your fingers caressing his cleanly shaved skin. He pushes his face into your hand in the answer, staring at you questioningly from under his long eyelashes.“I’m not going to lie to you: he’s handsome, exactly my type, in fact.”Both of you always try your best to be honest with each other, so you’re perfectly aware that your boyfriend is not indifferent to his best friend’s charm, however, there was never an occasion for you to tell him about your perspective. Not to mention that Seokmin has some issues with possessiveness and jealousy that he’s working on with your full support – you feel that in this case it’s even more important for him to know your exact thoughts on Mingyu. You don’t want anyone to end up hurt.“I might not love him in the slightest, but I can’t help but find him insanely attractive, Seokmin. I need you to know that, as I have no doubt that I’ll be highly aroused because of him, and I’d not try to hide it.”For a moment, he just stares at you in silence, before sighing.“Well, I’m also not going to lie, that I don’t feel jealousy right now. But I love you. I love you so much it sometimes hurts, and I know that I trust you no matter what,” he says, words spilling out of his mouth as fast as he can pronounce them.He’s staring up at you with such solemnity in his dark eyes that it takes your breath away for a moment.“I love you too,” you say without hesitation, and it’s his turn to be taken aback.You’re not really the type to express yourself with your words. Let alone confess your feelings in such straightforward way.“You love me?” he asks, as if not sure if he has heard you right.“Yeah, I’m surprised too.”Seokmin snickers, rolling his eyes, before turning his face slightly to the side to place a tender kiss on the palm of your hand. His stare drops to your lips mere seconds before you lean forward to connect them with his. He kisses you back eagerly, and for some time there’s nothing in this world beside his soft lips moving against yours. When you finally move away, both of you are slightly out of breath, but there are wide grins adorning your faces. Even without gaping at his beautifully flushed face, it takes you a moment to get a grip on yourself.“Now that I think about it, wouldn’t two men be too much to handle? How are you supposed to divide your attention between the two of us?” Seokmin asks after a few minutes of peaceful silence, curiosity evident in his voice.“Last time I checked, I had two hands,” you chuckle nonchalantly, resting your head on his shoulder.“You’re so cheeky, honestly,” Seokmin answers with a heavy sigh.“That’s why you love me,” you say, a smug expression appearing on your face.And then you rise your head to kiss him again.Opening your relationship, even if it’s only for a brief moment, it’s not a topic one could easily forget about, yet you manage to do so. Or at least manage to push it to the back of your mind – it’s not a burning issue by any means, and you have more important things to take care of in the meantime. It comes back to you one evening when Seokmin places down his cutlery and gives you a serious look.“I’ve talked with Mingyu a few days ago about that threesome idea, and today he told me that he’d like to join us.”Hearing that, you reach over the table to gently touch his hand.“Are you sure you’re okay with this?” you ask, entangling your fingers with his.“I know that you’ve told me countless times that you’re interested in the idea itself. But are you sure that you want me to have sex with him? Especially when he’s in love with me.”“You always ask such difficult questions,” Seokmin scoffs, rolling his eyes good-naturedly.“I don’t know how to explain that, really, I just know that I love you, and apparently this feeling is mutual. Call me an idiot blinded by love, but I highly doubt that he’s gonna come between us.”“Oh, that’s actually sweet,” you chuckle warmly, squeezing his hand.“Besides, while it’s not a secret that I too find Mingyu attractive, he simply cannot compete with you,” he says matter-of-factly, nonchalantly leaning back against his chair, but not letting go of your hand even for a moment.“And what’s better than two gorgeous people having sex in front of you?”“Tell me about it. Seeing you two, doing god-knows-what with your tongues and hands? I’m not sure if my heart can take it,” you huff out a laugh, shaking your head.“I can’t even begin to imagine that, I’m afraid I’m going to combust.”“Yeah, I know I’m insanely hot. But you can repeat that for me a few more times, I don’t mind.”You scoff at that, before a sinful though appears in your mind. With a smirk adorning your lips, you stand up and unhurriedly round the table.“I hope I won’t get a nasty burn then,” you say as you straddle his lap.His arms instinctively circle your waist, bringing you closer until your faces are mere millimetres apart.“You’re the only one that will be completely fine.”“I’ll have to take your word for that.”Later, neither of you will be able to recall who closed the gap first – before you knew it, you were kissing him as if your life depended on it. Not that you were the only one, as Seokmin’s lips moved against yours just as eagerly.“We should take it to the bedroom,” he murmurs between kisses, one of his hands already caressing your lower back under the jumper you’re wearing.“I don’t really feel like tidying up the whole kitchen after you tire me out to the limit, you know.”“Neither do I,” you laugh in the answer, your lips moving alongside his sharp jaw now.Seokmin stands up slowly, giving you time to firmly wrap your legs around his waist before he places one of his strong arms under your butt for a better support. You throw your arms around his neck, your fingers quickly finding their way into his thick locks.“Just don’t leave too many marks, I have a meeting tomorrow,” your boyfriend hums as he tries his best to divide his attention between walking towards the bedroom and kissing your neck.“Well,” you start nonchalantly, your fingers playing with the hair on the nape of his neck.“It seems that I must leave them in places that others can’t see.”You can feel his wide grin against your skin.“So it seems.”He doesn’t stop kissing you even when he puts you carefully on the bed, supporting himself with his elbows as he hovers above you. You pull him closer, letting him lay on top of you, your bodies pressed tightly against one another.“Seokmin,” you sigh happily as one of his hands slips under your jumper, the tips of his fingers outlining the shape of your breast before cupping it gently.His thumb brushes over your nipple a few times, waiting for it to harden, so he can roll it between his finger pads. Seokmin seems to be madly in love with your breast, practically showering them with affection every time he has a chance to see them or touch them.For a moment he stops kissing you, simply hiding his face in your neck as his hips start to move slowly but surely. Your breath becomes even heavier than before when you feel his hardening length pressing right against your centre, the friction driving you crazy.“I love to be surrounded by your scent, you know,” he groans lowly, the tip of his nose moving up and down your neck.“Yeah, I’ve already taken a notice when all my hoodies miraculously moved into your closet,” you choke out a laugh that turns into a whimper when he speeds up the tempo of his movements.Your legs tighten around his hips in desperate need to bring him closer.“Don’t tell me you don’t like it when I wear them. I won’t believe you.”“Of course I do,” you murmur, slipping your hands under his t-shirt.Your nails teasingly scratch the skin of his back, your hips moving along with his as you feel the pressure steadily building within your body. The fabric of your panties pleasantly rubs against your clit, causing you to buck your hips in search for friction.“In fact, my favourite outfit of yours consist of just my hoodie.”You push him away delicately, causing him to sit up. You follow right after him, your hands wandering over his thighs, brushing over his crotch as you kiss him.“So you can slap my naked ass whenever you want to?” Seokmin asks between kisses, the amusement clear in his voice.“I’d lie if I denied that fact.”You take of your pants swiftly, impatiently throwing them on the floor, and the panties follow soon after.“However, I also like to have your cock close at hand.”There’s a faint blush on his cheeks as he takes off his sweats, pulling them down his long legs along with the underwear. The dick in question presents itself proudly, the swollen head shiny from pre-cum that slowly rolls down his shaft all the way to the balls.“There’s nothing I like more than hearing those desperate noises you make when you’re on my mercy,” you hum as you carefully roll down his cock the condom you’ve taken from the night stand a moment ago.“We’ve matched perfectly then ‘cause I like being on your mercy,” he rasps, hungrily observing your hands that now wander teasingly close to his balls.You laugh in the answer, pushing him gently onto his back before you straddle his hips.“Hard to disagree, love,” you murmur, grabbing his shaft into your hand.For an agonizingly long moment for the both of you, you rub your pussy against it, coating the condom with your juices while teasing him all the same.“If you would be that kind, and finally put it in, I’d be grateful. Otherwise, I’m afraid I might simply turn us around, and put it in myself,” Seokmin says, looking up at you as his hands tenderly caress your sides.You only smile down at him, and take both of his hands into yours to place them firmly on your hips.“If you would be that kind,” you parrot back, raising a brow at him in amusement.“Thankfully for you, I like to think that I’m a very kind person.”With his hands supporting your weight now, you position the tip right in front of your entrance. As you start to slowly slide down his thick cock, Seokmin’s hips don’t move even for an inch, his fingers reassuringly drawing circles on your hipbones. From the countless conversations you had on this subject he knows very well that, because of the stretch, you need to take him in carefully, little by little, to not hurt yourself.“Everything fine?” he asks when you bottom out, his breath’s coming out short and fast.“Just a moment,” you answer, taking a few deep breaths yourself as you soothingly caress one of his hands.When you feel that you’re ready, you start to move: your hips rising slowly until only the head is still inside you, then fully taking him in once again. The tempo you set is slow at first, but with time you speed up, finding the rhythm that doesn’t weight your muscles too much.“You can move too, Seokmin,” you smile, leaning forward to press a kiss to his lips.He kisses you back, his hips starting to move as he tries to match the speed of your movements. You move together a little clumsily, but neither of you cares – your skin tingles from pleasure, from the affectionate touch of your lover, from the noises he makes. That’s what matters.It doesn’t take much time for your body to start shaking: it was a tiring day for you, and it’s clear that your muscles are finally losing their strength. You hide your face in his neck, quiet noises escaping your lips from time to time as you make love to your boyfriend. Sensing your fatigue, Seokmin turns you around so that now he’s the one on top.“You know, no matter the position, you always look gorgeous,” he chuckles, placing his weight on his forearms.“That goes without saying,” you answer cheekily as you pull his face closer and kiss him.As your legs embrace his hips, you can’t help but marvel over how cute he looks right now: his tangled locks plastered to his sweaty forehead, cheeks and neck deeply flushed, and a boyish smile adorning his handsome face. Not to mention the quiet grunts and sighs that sound suspiciously close to your name as his cock swiftly moves in and out of you, your muscles clenching deliciously.“I’m close,” he chokes out, hiding his face in your neck.His hips stutter slightly, movement losing its previous speed as he gets closer and closer to his orgasm. One of his hands slips between your sweaty bodies to rub your clit, causing you to moan softly right into his ear. He knows your body well, and he never hesitates to use that knowledge to make you see stars.“I love it when you tighten around me, Jesus,” Seokmin pants out mere moments before your orgasm hits you.Your nails rake down his back as the violent wave of pleasure crushes through your tired body, surely leaving marks on his unblemished skin. Seokmin seems to like it a lot, as he grunts out your name in surprise, clearly coming earlier than he expected it to happen. You can still feel his cock pulsating inside you, as you try to catch your breath, one of your hands finding its way into his tangled hair.“Honestly, I could’ve just fucked you on that kitchen table,” he murmurs sleepily into your ear.You caress his head with a quiet laugh.“Next time, love, next time.” Copyright © 2020-2022 by byzantiumshades.
