MARK LEE IS an enigma.
And that’s your personal opinion by the way. Some would disagree but as a person who’s discovered (maybe unleashed is a better word) a different side of Mark— a completely different side— you were quite confident in your opinion.
And it shows in many different ways.
Dating him is a lot of work, you weren’t going to lie. It takes patience working around things for Mark. And completely understandable, given that he’s a full-blown idol that has the busiest and tightest schedule you’ve ever seen. To be honest, you couldn’t believe how much work he took head-on until you had started seeing him. And yet somehow, he made time for you.
It’s not the easiest to secretly date an idol and Mark makes it worth it. There’s a thrill as well, aside from the downfalls that of course come with hiding your romantic relationship. Which is another example of his that you’re fascinated with.
Like just yesterday, after dance practice, Mark had stolen a moment to go to the bathroom and you hopped out of the room a few minutes later. You were able to grab Mark’s hand in yours and lead him into an empty practice room where his cute, shy kisses were explored.
It’s incredibly adorable (and strangely arousing) having someone inexperienced to play with. It made sense, seeing as Mark had never had much time to particularly date during trainee period.
But that part is not what was complete mystery to you, it was that… Mark Lee was a little bit of a natural.
Like the way he nips at the skin of your lips, or when he gets enough confidence to drag his hands down your back, squeeze, and then pull you in closer by the apex of your thighs… You genuinely want to jump his bones whenever he does that.
Even with Mark voicing his inexperience, it’s well hidden as he grows more confident in his movements. You’ve learned to let him explore by himself instead of you directly giving him what you know you like in intimacy.
It’s all because you’re teaching me, noona, he says, but… you know better.
His intuition has gotten him pretty far in life. You feel that even though he was quite new to sex, this was just a new obstacle Mark was excited to explore more. Like right now as you straddle Mark’s lap in the empty studio, his hands deftly dragging their way up your sides with nails scratching, you certainly know better.
|—————|
The situation and time had presented themselves. Even though it was a little risky, you had managed to sneak into Mark's room after a long day of schedules. You were 99% sure the boys on the floor were dead asleep, it being five A.M. in the morning. The both of you direly needed release though.
It was bound to happen today, one way or another. The entire day, the two of you were wired up like horny teenagers, dying to touch one another. Mark was a little too obvious with his staring at work. You wouldn’t be surprised if one of your coworkers questioned the two of you a little.
This brings you to also want Mark to learn how to rein himself in a little. What better way on how to teach him how to be quiet and subtle while torturing the poor boy in his dorm?
It’s all heavy breathing between you two as you tilt your head to connect lips. Mark is bothered and you can by the bulge you’re sat upon. He thrusts up occasionally, wanting you to reciprocate the action but you’re resisting.
You’ve been waiting for Mark to beg for it. He was too fun. His reactions riled you up.
As you lick into his mouth once more, moaning weakly, Mark groans himself but a lot louder. His dark hair is all messed up, his shirt wrinkled from your tight grip, looking deliciously fucked out already from your touches.
“Shh…” You whisper, pulling back to place your palms behind you on Mark’s knees. Your shirt has quite a deep V-neck and it attracts Mark’s eyes shamelessly. You would’ve thought that by now, Mark wouldn’t stop blushing for such vulgar behavior, but he still looks away after, wide doe eyes looking at yours.
“You don’t want to wake up your hyungs, do you? You all have a very big day tomorrow.” You mutter, coming back in to pepper kisses on Mark’s jawline. The desire to suck love bites all down Mark’s pretty skin was tempting, but you knew it would get the boy into a lot of trouble very quickly.
Airy, shaking inhales and a tentative squeeze at your hips are all you get in response. Your eyes twinkle as you scoot closer to Mark’s hard-on, grinding sensually.
Mark bites his lip harshly, grip now tight. Blowing out a rough exhale, his voice is high and pleading.
“Please… don’t do that, noona. I won’t be able to be quiet if you do that.”
Your dominant hand begins to put in work, nails dragging through the trail of hair running down into Mark’s sweats. You grasp onto Mark’s boxers, pressing a thumb into his head’s slit. Mark bites his hand, a high wince of pleasure escaping his lips.
“I want to make you feel good… will you let me?” You blink slowly, alluring eyes set on Mark’s fucked out face.
“I don’t… I won’t be able to keep quiet—”
“Try your best, baby. Or do you want me to gag you?”
Mark moans at the suggestion, chest caving in at the thought. Getting off his lap, you turn around and slowly peel off your sleep shorts. You’re slightly surprised when Mark’s hand places itself on your right asscheek.
He grasps the meat, nervous but in fascination. He’s about to see pussy and your ass takes his attention.
Okay, information stored.
Crossing your arms as you grasp the hem of your shirt, you twist back around to rip off your top as well. His eyes roam your breasts without shame now, mouth open in awe. It’s like he’s not aware of his hands as they splay at your stomach, circling your belly button before rubbing fingertips up the valley of your breasts.
You let Mark explore a little as you sneak your panties down your legs, shaking them off and picking them up with your toes. Bunching the lace underwear, you hang it from your wrist and climb back onto Mark with a thigh between his own, the stiff fabric of his sweats rubbing on your swollen clit.
A quiet moan tears itself from your throat and Mark licks his lips at the sound, beginning to watch you grind yourself on him. He aids the movement of your hips, cupping beneath the underside of your right breast.
Guiding his hand to hold you, his larger palm envelops the tissue. You aid in squeezing your boob, getting in Mark’s ear to moan.
“You make me feel so good, Mark.” Mewling, you wrap your arms around him as he shivers. Desperately needing to feel more skin, you pull back and rip Mark’s hands off your breasts with determination, yanking at the shirt hiding Mark’s lean muscle from you.
The younger boy lets you do it, shyly looking away as you ogle. You’re careful to scratch down his chest and massage his abdomen. Mark jerks again from the confines of his pants, whining noisily into your hair.
You had forgotten about the piece of lace, dangling it between you two. Mark watches in rapture, his eyes glued to your mouth, all swole and deepened from his lips. I did that, he thinks proudly.
“Open up wide for me, baby.”
You pinch at his chin and Mark willingly opens his mouth, letting you stuff the fabric in. Just to test, you press your knee against Mark’s bulge and he groans, head thrown back.
A sudden rush of power runs over your skin and your fingers grip at Mark’s neck. Raking your teeth against the large vein that runs down his jugular, Mark wiggles below you, stringed-out.
“What a good boy…” You praise, brushing through his hair. Mark’s eyelashes flutter and you kiss at his eyelids before pulling at his crown roughly.
Mark moans past the lace and you smirk at his submissiveness. You could get used to it.
“Make a pretty little sound I think is too loud and no orgasm for you. Understood?”
He nods, eyes pleading as he grips your shoulders. Climbing off Mark once more, you settle on your knees, legs folded beneath you. He lifts his hips to help you take off his sweats. Mark begins to pull at his boxers too but your quick hands stop him.
“Let me.” Smugly, you lean closer and lick at his tip through the black cotton. The younger boy’s hand grabs at yours to the side and you allow it for his comfort. The way his bare chest rises up and down unsteadily for you forces a smirk to rise on your features. The thin sheen of sweat forming on the surface of Mark’s skin was appealing in this low lamplight.
You can tell he’s dying to beg more but doesn’t want to make any unnecessary sound, afraid to lose his chance of coming. It wasn’t like you were cruel; you would let Mark cum in the end but the game to get there was nice, no?
Digging your fingernails into his warm thighs, you breathe heavily on him, feeling the thick muscle beneath your palm tense.
“Relax baby. Just let me take care of you, huh?” You whisper, bringing your conjoined hands to your lips and kissing Mark’s knuckles. He nods, visibly slacking some and sighing heavily past your panties as his head throws back in pleasure.
Guiding Mark to lift his hips, you pull his boxers off slowly, letting it drag on. His cock jumps where it lays on his abdomen, excited for the tight cavern of your mouth to envelop him fully. Mark has had a fascination with your mouth from the beginning; sparks of joy came from licking and pulling at them with your teeth just to watch your toy squirm at the sight.
Doing exactly that, his eyes gravitate toward your wide eyes and curling lips, flying between the two. The amount of desire to just yank you down onto him burned in his bones but Mark resisted, knowing patience would get him there eventually.
Bringing two pads of your fingers to your tongue, you press down hard, letting saliva gather on your digits and then circle your clit once. You can’t help the way your face scrunches at the sensation, wanting to rub an orgasm out of yourself so badly. Mark watches with rapt attention, as your now soaking fingers brush down a vein on his cock.
His hips twist and turn, needing more stimulation. A small wince passes the fabric in his mouth and your sharp eyes glance up, warning just once with a glare.
Being careful with your teeth, you lean closer, taking Mark’s tip in and hollowing out the air in your mouth to suck harshly. He hisses past the gag, moaning deep and long as you push down farther, your flexing throat spasming around him.
Your tight swallow around his length pulls a groan from Mark and suddenly, you’re moving like an expert up and down on him, free hand going up and down on what you couldn’t reach. Mark untangles his hand from yours to brush at your hair but you deny him the opportunity, forcing poor him to keep his hands to himself. Trying to use it to his advantage, Mark tries to muffle himself more but it doesn’t really work.
The loudest moan of his yet yanks your head off his cock and Mark almost wants to cry at the loss of contact. He’s practically whimpering, wide doe eyes looking down at you in desperation but your jaw shifts in annoyance. He had been twisting and bucking the entire time you’ve been going down on him.
You straddle Mark’s lap rather aggressively, pulling your lace panties out his mouth. “Why don’t you know how to behave, baby?” You grind on Mark, his wet trip rubbing deliciously at your entrance. “What did I tell you, huh?”
Mark clenches at your hips tightly, not listening as he lifts at your center, so needy and eager to be in your pussy. You struggle to muffle his next sounds, palm slapping at his mouth as you lift yourself away from his longing thrusts up into you.
“Naughty…” You lean into his ear, hissing your disappointment, “Naughty boy…”
Climbing off to his side fully this time, your palms grasp Mark’s shoulders and roughly push him down on the bed. His back lands with a thump, one hand death-gripping the sheets beside his head. Mark’s occupied wrist is traveling up and down on his length and you dig your nails into them roughly, hoping he would let loose on his own but you were wrong.
Marks keeps going, barely even registering anything but your body as he focuses on your fingers wrapping his on his dick, your tits up in his face. You can’t help the arousal slicking your pussy either, thighs clenching as the small gasps escape Mark’s red, bitten lips.
You know you should stop him; force him to just sit back and let you pleasure yourself to completion but the absolute carnal desire to watch Mark make himself orgasm was stronger.
He’s completely out of his mind as the hand laid near his ear gathers around his throat, flexing when he squeezes and chokes himself. A rough, deep whisper of your name pasts Mark’s lips and you connect eyes as your thighs widen. Might as well give him a show.
Wrapping your own hand around your throat, you dip your fingers into your collarbone, around your nipples, and play. Licking your fingers again, you push at your abdomen and savor that pulsing feeling of your walls, aching for Mark to fill you up. You swear harshly and finally widen your lips for Mark to see. Slick drips from you and the younger boy exhales so roughly, it sounded like it winded him.
Mark’s wrist moves faster and you know he’s close as you quickly going down between his thighs to lick at his length. Your blood boils from how good Mark makes you feel, chest heating from how much you want Mark to cum.
Putting aside how much you ache to shove Mark’s dick in you, you suckle around Mark’s tight hold on his cock.
“Mark, cum, please.” Whining, you grasp his sides, mouth open wide as your eyes plead too.
Heaving, Mark nods rapidly, gaze glued to your face as he leans on one elbow, aiming into your ready mouth. Groan long and slow, he releases his seed into your mouth, pumping his length to watch it hit your lips and land on your pliant tongue.
Drool hangs from your chin and Mark breathlessly swipes at it, roughly yanking you closer to kiss. His tongue explores once more and you let him, appreciating Mark’s assertive and bold control of your body.
“Fuck, you’re so good to me, noona. So good.” Mark pulls apart to tell you, right hand cupping your chin and pinching for emphasis. His left hand is conveniently between your open legs and your elbows weaken when he brushes at your hard clit, begging to be touched and played with.
Your eyes close in pleasure, your mouth silently open and asking for more. Gently using your chin to guide your body to sit up, Mark runs his hands on every surface of skin he can touch, pulling at your hips to bring your chest closer to his awaiting mouth.
Still leaning on his left elbow, Mark breathes hot on your breasts before biting at your nipples. You cave in at the feeling, cradling Mark’s head and giving up your control.
“Fuck… Mark, I want you. Please…” It’s your turn to buck up into Mark’s hold, his fingers still playing with the sticky mess between your thighs.
“Should I…” Mark nervously looks up to you, blinking quick, “Can I eat you out?”
You don’t mean to moan so loud. You’re ignoring your own warnings. “Fuck, yes. Yes, yes, yes.”
Mark jumps up, slowly pushing you down and grasping at the underside of your knees to pull your body closer to the bed’s edge.
“I don’t know how to…” Mark whispers cautiously into the night. Smiling, you look down and grin at the look on his face.
“That’s okay. Just explore. Whatever I don’t like, I’ll tell you…”
Nodding seriously, his eyes concentrate on your core. Normally, you would start intensely blushing if someone were to be studying you this closely but it was Mark. He was treating you like a delicate experiment. It was quite adorable.
His endearing eyes latch onto yours once more before his puckered lips place a small kiss on your clit. Sighing, you close your eyes to focus on Mark’s pleasure.
“Do what feels right, baby.”
“Okay, noona.”
His roughened voice muttering that into the night sent vibrations straight to your core. Mark watches your wetness escape your pulsing hole in fascination. The pad of his pointer finger wipes at it, bringing it to his mouth. It’s not a bad taste, he thinks.
You almost want to scream in impatience but stop yourself. As if sensing it, Mark finally does something, asking first, “You’ll tell me if it hurts?”
“Yes. Yes, baby, please. I’m not fragile.”
Mark pushes his pointer finger up to the knuckle slowly, marveling at how your tight walls fight to keep his digit in. “Oh.”
You can’t help but breathlessly laugh at Mark’s meek noise, shifting to move his finger lightly. Mark gets the hint and diligently starts fucking his finger in and out, studying your expression closely. He brings his mouth to your clit, tonguing and flicking at it. You jerk at the sudden sensation, biting around your middle finger to stop a steady flow of moans.
“Do you like it, noona?”
Lightly, you let out a moan of approval, going down to snake your hands into Mark’s head of hair. “Another finger.”
Mark does as he’s told obediently, his middle finger soon joining beside his pointer. Wriggling at the pleasure, you dig your heel into Mark’s back. “Faster, please.”
High noises escape your mouth and you try your best to make them as small in volume as possible. Mark presses his entire tongue down on your swollen clit and you grind up into it, the texture driving you up the wall.
When his fingers slightly curl up at the change in position, you whine noisily. Mark presses into your walls as he learns quickly, drinking up the sounds he’s drawing from you. A seed of desire plants back into his abdomen as your breasts move at your eagerness, your hips bringing you back and forth on Mark’s fingers.
Mark slyly snakes his other hand away from your thighs and down to his twitching length again, amazed at how quickly you get him turned on.
It hasn’t even been that long but all Mark can think about is pressing his hips flush to yours, making your ankles hang off his shoulders and your body shake with his thrusts. Or maybe pull you to lay on your side and clasp your thighs together; fuck that tight space between them and come all over your pretty stomach. Or maybe… maybe… you’ll let him bend you over, press your cheek into the mattress and arch your back… guide his length into your pussy and watch his essence drip down onto his sheets.
Mark groans around your lips, sucking at your clit harshly. The vibration causes your muscles to spasm.
“Fuck, Mark… I’m about to cum…” You whine, tugging at Mark’s hair harshly. He gets much more eager, pushing his fingers in and out as far as he could go, faster, and faster. Rocking with his motions, you pull at Mark’s busy hand at his throbbing member to drag up your body and grasp at your neck.
With a good squeeze of your breasts and Mark’s sharp suckle of your clit, you reach completion. Gasps suck in air from your mouth, vision blurring in ecstasy as you turn your head, trying to block out your sounds.
You pull at Mark’s head and his moving hand, oversensitive now that you’ve come. Reluctantly, Mark lets go, climbing back on the bed to brush your hair away from your flustered face and rub at the skin of your trembling legs.
“Are you alright, noona?” Mark wonders, wide eyes imploring and traveling everywhere on your body.
Yanking him closer, you lick into his mouth and pull at Mark’s elbows for him to press onto you. He tries desperately to not let you know he’s hard again but fails in the end, jerking when his cock presses on your soft abdomen.
Mark swears around your mouth and you bite his bottom lip for it. Your heels run up and down Mark’s sweaty back, drawing him into grinding on you again. His tip catches at your entrance, both of you moaning against each other’s lips.
“How do you want me?” You whisper seductively, eyes low.
Mark buckles at your question, his fantasy coming to life as his elbows beside your face shake. Lightly, you push yourself up, the younger boy only able to savor the feeling of your breasts against his chest for a moment before you’re twisting yourself around. You back your hips up to hit Mark’s, his warm hands grasping at your waist.
“Noona…”
You look back at him, lashes fluttering as you nestle your hips closer. “You don’t want to?”
Widening your legs, you bring your fingers to grip his length lightly, inviting Mark closer.
“Shit…” Mark swears, hurriedly guiding his tip to your entrance. He enters slowly, hands tightening around your waist so hard, it hurts. His dull nails dig into you and you wince at both that and the way Mark’s girth stretches you out.
He bottoms, stilling and blowing cold air against your pretty back in trying exhales to control his breathing. A palm runs down your skin, swiping at your hair to watch your equally pretty face take him in so well.
“Move, Mark… fuck me, please…”
He doesn’t need to be told twice.
Pulling out almost all the way, Mark watches your slick cover his cock, lust circling in the pit of his stomach. It lights a fire in his veins, causing the surface of his skin to warm and his body to tense. He savors thrusting forward, loving the pliant way your walls accommodate Mark’s cock.
“You feel like heaven, fuck.” Grasping your hips tighter, Mark rocks you leisurely. He would appreciate this moment more if you weren’t forcing yourself to be so quiet.
“Feels so good, baby. So…” A moan climbs up involuntarily and you bring your mouth into the mattress, hoping it will dampen it.
Mark leaves you empty and whipping your head around, he’s brushing a hand through his hair, sitting back on his heels.
“What’s wrong?” You ask worriedly, turning to lay on your back.
Mark breathes out, a crinkly grin growing eventually. “Nothing, sorry. I just needed a breather. And…” He starts to hover on top of you, his weight comforting as Mark lays down. “I want to see your face.”
It’s not that often you’re flustered but you do become so, the combination of Mark’s smile and his comment forcing you to turn your face to the side.
Mark is proud of himself, lining up to bury inside once more and cupping the crook of your jaw. His lips peck yours once and your cheeks burn with heat, his loving attention too much to handle.
He jerks forward, saving the image of your fucked-out face in the back of his head for the future. Interlocking your fingers behind Mark’s neck, you bring him in closer, licking at the sweat on his skin.
He gasps when you squeeze tight around him, moaning softly into your collarbone. You moan, eyes rolling back as Mark goes harder. He starts slamming his cock into you, grip on your face so tight now.
His hips falter, grinding now as his speed becomes sporadic. Running your nails down Mark’s back, you coax his groan out again. This time he’s emptying himself inside your walls and you feel warm and comforted.
Slowly, he pulls out, shakily sitting down on his hunches. You’re both trying to catch your breaths but you stutter, arching when Mark widens your legs to watch his cum escape.
His eyes are glued to your cunt and your inner thighs clench at the lust they hold, pupils so dark they also swallow his beautiful irises.
Moaning tiredly, you tug at Mark’s arms. You’re cold now that you’re not so worked up. He’s willing in the movement, going to embrace you from behind and peck at the dots on your back.
“Don’t you want a towel to clean up, noona?”
Sighing in content, you lean back into Mark’s chest. “Yes, just give me a second.”
There’s only several seconds before Mark asks. “Was… was that okay? I don’t—”
“Baby… I promise when I say this. You did amazing.”
“Yeah?”
“You’re a quick learner.”
Mark leans on one elbow again, a little shaky. A grin is planted on his face as he tilts over you.
“Really?”
Giggling, you place a palm on his cheek and crinkle your eyes from smiling hard. “I promise, baby.”
Mark falls back into the pillows at that and you can feel his chest fall back down in relief.
“… You know what you need to work on though?”
There’s anxiety in your boyfriend’s voice as he answers. “Uh, yeah?”
Looking back, there’s a blank look on Mark’s face.
“Your noise level. Think your hyungs know we just fucked?”
“What I think is that you need to consider that for yourself, noona. Especially towards the end.”
“... I’ll bring that gag back, asshole.”
His Adam’s apple bobs and you chuckle as you head to the bathroom.
Chrysoprase had been a very quick learner when he arrived in Ankh-Morpork. He began with an important lesson: hitting people was thuggery. Paying other people to do the hitting on your behalf was good business.
