#jongseobxreader

jongseob had tried to ignore you for over an hour. his glasses kept slipping down his nose from how many times he’d looked down at his workbook, only to be distracted again by the soft hum of your voice, your hand brushing too close to his thigh, your lazy giggles every time you caught him squirming. he had begged you. begged. to let him get through at least this one chapter. he had a physics quiz tomorrow. he needed this grade.

but you were no help.

you were wearing his hoodie, but nothing underneath. he could see the soft curve of your bare thighs where you sat across from him on the bed, feet tangled together. his pen had dropped somewhere near your knee. you’d made a show of picking it up. slow, stretching just enough for the hem to ride up and flash the pretty dip between your thighs. jongseob had choked, muttered a breathless “please, stop” that didn’t sound convincing at all.

you: “stop what?”

your voice was all syrup, all innocent cruelty. he looked up from the page, cheeks already red.

j: “you know what you’re doing…”

he did that thing again where he licked his lips and immediately regretted it. you watched him. your hand crept forward. fingers slipped up to where his lap was covered by a too-thin blanket.

you: “you’re so tense. i’m helping you relax.”

j: “i… i c-can’t focus if you-”

you crawled across the mattress until your face was in his neck, until your hand was curled around his cock through his sweats, rubbing slow just to hear the way he whimpered. jongseob was panting already, his eyes screwed shut behind his glasses. he looked so helpless. head tilted back, adam’s apple twitching, body trembling just from your palm. he always got like this when you teased him. but tonight he cracked.

your palm squeezed. his hips bucked. he grabbed your wrist.

j: “n-no. no more.”

you blinked. surprised by the edge in his tone, even more surprised when he pushed your hand away and shoved the book off the bed. he stared at you for a second, like he wasn’t sure he meant to do that, then swallowed hard.

j: “lay down.”

you tilted your head, smirking.

you: “are you mad at me?”

j: “yes. lay down.”

his voice, shaking.

your heart thudded. you obeyed. and for a second you thought he might crumble again. but he didn’t. jongseob took off his glasses and set them down like he was about to perform surgery. his hands were trembling as he hovered over you. he stared down at your body like he wasn’t allowed to touch it, like one wrong move would make you disappear.

then he touched you. slowly, cautiously. his palm on your stomach, dragging up to cup your chest under the hoodie. you gasped. he whimpered.

j: “i’m not supposed to… but you’re not letting me study… so…”

you didn’t even get the chance to tease him again. because suddenly he was kissing your neck, then lower, licking across your chest with shaky, eager breaths, mumbling little curses into your skin. your hoodie bunched up to your ribs. he slid down between your thighs, face red, hands gripping your hips like he needed permission.

j: “can i… can i taste you?”

you nodded. breathless. he licked his lips and dropped his head, burying it between your legs with a desperate moan like he’d needed this more than air. his tongue was clumsy at first. nervous, unsure. but he made up for it with how hungry he was. whining softly, mouth dragging over you again and again until your back arched.

you were tugging his hair before long, thighs trembling around his head. and still he didn’t stop. your teasing was long forgotten. jongseob was shaking, humping the mattress, fully red in the face while he licked you through your moans. you tried to pull him up, he refused.

j: “not until you cum. i… i want it. please…”

you came with his name tangled on your tongue, body writhing under his mouth. when he finally pulled away, his lips were wet, eyes glazed. you tugged him up by the hoodie strings and kissed him, catching your own taste on his tongue.

he moaned into your mouth. hips twitching against your thigh.

you: “you still mad?”

j: “i need to fuck you.”

jongseob whimpered. pulled your hips into his lap. and the studying was forgotten.

his hands were shaking so hard you almost took over for him. almost. but something in the way he looked at you made you still. like he needed to be the one to do this. like he’d finally snapped and couldn’t bear being teased anymore without giving something back. his fingers fumbled with the waistband of your shorts, pushing them down with a soft, breathless gasp when your thighs spread.

j: “i-i don’t know if i can do it right… just… tell me if i mess up.”

he was already hard, tenting his sweats, the head of his cock damp and obvious through the fabric. you could see how bad he wanted it, wanted you. and yet even now, he hesitated, hovering over your body like he was afraid he might break you.

you reached down and tugged at his waistband.

you: “take these off. you’re already leaking, seob.”

he whined softly, almost embarrassed, but obeyed. his sweats dropped, cock springing free. pretty and flushed, twitching from the pressure he’d built up all night. when he climbed between your thighs, he lined himself up, eyes locked to yours like he was waiting for you to stop him. you didn’t.

he pushed in with a shaky breath.

j: “f-fuck… it’s warm… you’re warm…”

his voice broke as he bottomed out, hips trembling above yours. you moaned under him, hands gripping his arms as he sank deeper, cock stretching you open inch by inch. he wasn’t rough. he didn’t know how to be rough, but he was hungry.

he started moving slowly. short thrusts, hips stuttering as he tried to keep control. you could feel how hard he was trying to hold back. biting his lip, forehead damp, little whimpers slipping through when your walls clenched.

you: “faster. don’t hold back, seob.”

j: “i-i can’t… i’ll cum too fast- fuck-”

but his hips picked up anyway. the slick sound of skin against skin filled the room, his cock dragging deep with each thrust. he leaned in, hiding his face in your neck. moaning every time you clenched around him, panting your name like a prayer.

j: “you feel so good, i c-can’t think- y-you kept teasing, i- mmph-”

you dug your nails into his back and rocked your hips up to meet him. he gasped, pace faltering.

you: “gonna cum already?”

j: “n-no- i mean- y-yeah- i’m trying not to- fuck, i can’t-”

he started shaking. the moment your walls clenched again, his whole body stiffened and he moaned so sweet and high in your ear. his cock throbbed as he spilled inside you, hips jerking through each pulse, breath ragged and broken.

j: “s-sorry- i didn’t last… i didn’t…”

you: “you didn’t even try to hold back, seobie.”

j: “i-i couldn’t help it. you were so tight. so warm. i… i c-can go again though. i’ll make you cum. just give me a second-”

he pulled out slowly, cock softening but still twitching. you felt the wetness leak down your thighs. he watched it with wide eyes, cheeks flushed, hands already fumbling to touch you again. this time with less hesitation.

j: “i-i wanna taste it… all of it… gonna make you cum with my mouth again, please-”

and just like that, nerdy, flustered jongseob had dropped back to his knees between your thighs. studying abandoned. quiz forgotten. only you in his mind now. his only subject, his favorite test.

this time it was different. messier. needier. his tongue lapped through the slick mix of you and him like he’d lost control of himself. moaning, licking, gasping when your hips bucked and your thighs tightened around his head. he didn’t slow down.

he growled into your pussy.

j: “keep your legs open. don’t move.”

his voice was muffled, low, soaked in heat and embarrassment and command. you gasped, already twitching under his tongue, barely able to handle how sloppy he was. his hands dug into your thighs, thumbs spreading you wider as he focused on your clit. sucking and flicking his tongue, messy and insistent.

you reached for his hair, but he caught your wrist and pinned it to the bed.

j: “let me do it. i’m not stopping until you cum.”

his mouth was everywhere. soft licks, sharp flicks, his lips wrapping around your clit just right. and every time your hips twitched, he pressed them back down like he was memorizing what made you squirm. his cock was still twitching, half-hard against the bed, drooling onto the sheets. but he didn’t care. not yet.

you: “seob- fuck- baby i’m-”

j: “cum. cum on my tongue, please.”

you broke with a gasp. hips jerking, body arching into his face as your orgasm hit, hot and blinding and so much after how long he’d teased you. he held you down through it, lapping up everything you gave him, moaning like he was getting off from your taste alone.

he didn’t stop until your legs were trembling. until your cunt twitched under his tongue, overstimulated and soaked. then he finally looked up. mouth and chin glossy, face flushed, eyes wild.

j: “did i… do okay?”

you nodded weakly. and he smiled, proud but still a little shy, crawling up your body to kiss you with his cum-slick lips.

j: “i think i wanna study like this from now on.”

you laughed breathlessly, pulling him back down.

you: “who knew nerds were so good with their tongues.”

j: “i’ll get better. i swear. just… let me try again later.”

you grinned. he already was.
