#computer science assignment assignment help

the faint scent of his woody cologne mixed with the smell of old ramen lingered in the air. outside the window, the university campus was quiet under the late night haze, most students already asleep or cramming elsewhere

heeseung sat on the edge of his bed wearing nothing but a loose black t-shirt, his long legs spread wide. his dark hair was messy from nervously running his fingers through it, and a deep flush already colored his sharp cheekbones

his cock stood hard and flushed against his stomach, the silver piercings catching the lamplight — six evenly spaced barbells running neatly along the sensitive underside from just below the head down toward the base. he looked equal parts nervous and eager, exactly the way you loved him in these moments

your arrangement hadn’t started out this intensely. you first met heeseung during freshman orientation week nearly two years ago. he was the quiet, tall guy in oversized hoodies who sat in the back row of the intro programming lab

when your code kept throwing errors on the simplest “Hello World” assignment, he leaned over without a word and fixed it in under thirty seconds with a few keystrokes and a shy smile. “It’s the semicolon,” he’d murmured

that small act of kindness turned into regular study sessions in the library, late night snack runs to the 24-hour convenience store, and long conversations about everything from anime to the absurdity of group projects

heeseung was sweet in that unassuming way —smart, a little socially awkward, always willing to help debug your code or explain complex concepts until they made sense. you became close friends fast

the tension built gradually lingering eye contact during movie nights in his dorm, his hand brushing yours a second too long when passing notes, the way he’d stare at your lips when you laughed. neither of you acknowledged it until last semester after brutal midterms

you’d both gotten drunk on cheap soju in this very room, celebrating the end of exams. one tipsy confession about feeling stressed and touch starved led to a heated kiss, then clumsy hands sliding under clothes

heeseung had been surprisingly vocal that night —whimpering, begging, letting you take complete control as you rode him. The sex was mind blowing, and something shifted

the next morning, awkward but honest, you suggested keeping it casual friends with benefits. stress relief with no strings, no jealousy, just two close friends helping each other feel good. he agreed immediately, cheeks pink, admitting he’d wanted you for months

what neither of you expected was how perfectly submissive he became with you. and then there were the piercings.

heeseung had gotten the jacob’s ladder on a stupid freshman dare after losing a bet during orientation games six silver barbells. they healed well, and though he never told anyone else, he quickly learned just how hypersensitive they made him.

the first time you discovered them, he came embarrassingly fast from just a few strokes of your tongue. ever since, these private sessions revolved heavily around them. he trusted you completely —enough to let go and become the whiny, needy version of himself that no one else ever saw.

tonight, after weeks of OS project stress, he needed this badly. “we’ve been doing this for months,” he murmured, voice already breathy, “and I still get so nervous it’s embarrassing how fast I lose it every time you use your mouth.”

you smiled, kneeling between his thighs and running your palms up the tense muscles. “you don’t have to hold back with me just let go hmm.”

you started slow, pressing open mouthed kisses along his inner thighs, sucking lightly until faint red marks appeared. heeseung shivered, soft gasps escaping him. when your breath finally ghosted over his cock, it twitched hard, a bead of precum sliding down toward the top piercing.

your tongue dragged flat and slow from the very base of his shaft upward.

the first piercing met your warm tongue. you pressed firmly against the smooth silver barbell, feeling it shift and roll against the thick vein underneath. heeseung jolted violently, hips bucking forward as a sharp whine tore from his throat.

“Ah—! fuck that lowest one always feels so deep,” he gasped. “the metal’s cooler than your tongue… the contrast—ahh—”

you hummed and licked it again, slower, dragging the flat of your tongue back and forth over the barbell multiple times. each pass made his thighs tremble.

you moved to the second piercing, flicking the little ball at the end with the tip of your tongue before pressing down hard, trapping the metal against sensitive skin.

heeseung’s hand flew to your hair, fingers threading in but not pulling. “oh god… please, more like that it sends these little shocks straight up my spine.”

by the third barbell, his breathing was ragged. you swirled your tongue around it in tight circles, then sucked gently on the skin beside it so the piercing pressed inward. his moans grew higher, whinier. “right there — your tongue is so wet and warm on them I can’t — I can’t stay still—”

you wrapped your fingers around the base, thumb gently rubbing the lowest piercing while your mouth focused higher. taking the flushed head between your lips, you immediately attacked the fourth barbell. you flicked it rapidly, then dragged your tongue heavily over it, feeling every ridge and bump of the metal.

heeseung’s head fell back, exposing his throat as a long, broken moan filled the room. “fuck— that one’s so sensitive you’re killing me please don’t stop I need it.”

his hips rolled involuntarily, pushing another inch into your mouth. you relaxed your throat and took him deeper, letting the fifth piercing slide across your tongue. you pressed the barbell firmly upward, rubbing it side to side while hollowing your cheeks.

a string of desperate whimpers spilled from him. “ah—ahh— i’m sorry, I keep thrusting— it just feels too good your mouth is so hot and wet around my piercings ”

you pulled back slightly, letting his cock rest on your tongue as you looked up at him. his eyes were glassy, cheeks burning red, lips parted. “be a good boy and let me enjoy every single one,” you whispered.he nodded frantically. “I’ll be good I promise I’m yours tonight just please keep playing with them.”

you sank down again, taking him deeper than before. this time you dragged your tongue in one long, luxurious, torturously slow stroke from the lowest barbell all the way to the top. each of the six silver barbells clicked and rolled against your tongue one by one. heeseung’s entire body shuddered hard, thighs clamping around your shoulders before he forced them wider again.

“oh my god— every single one i feel all of them it’s too much— too intense—” his voice cracked into a whine as you repeated the motion, faster this time, flicking each piercing on the way up and pressing on the way down.

you focused intensely on the uppermost barbell, the most sensitive one just under the head. you swirled your tongue around it relentlessly, flicking the silver ball, then sucking lightly so the bar pressed firmly into the bundle of nerves. heeseung’s hips jerked sharply, pushing his cock deeper into your throat as his control slipped completely.

“I’m— I’m already so close— fuck, I’m sorry— your tongue on that one destroys me every time—!”

you didn’t let up. you sucked harder, tongue working that top piercing in tight, fast circles while your hand stroked the base, thumb rubbing the lower bars. heeseung’s whines turned into desperate, broken sobs of pleasure. his fingers tightened in your hair, hips making small, helpless thrusts as he chased the sensation.

“I can’t hold it— I’m gonna cum— please— I’m so sorry it’s so fast—!”

his first orgasm hit him like a wave. he came with a loud, cracked moan, thick pulses flooding your throat as his whole body shook uncontrollably. you swallowed around him, still flicking your tongue gently over the piercings through every twitch and aftershock. even after he finished, his cock stayed rock hard, oversensitive and leaking.

heeseung panted heavily, looking down with teary eyes. “I did it again came so embarrassingly fast. we’ve been fuck buddies for so long and I still can’t last when you play with my ladder like that.”

you licked your lips and dragged your tongue slowly over the entire underside again, pressing every barbell. he yelped, oversensitive and squirming. “too much—ahh! it’s too sensitive right after— but fuck, don’t stop please keep going.”

you took him back into your mouth, gentler but no less thorough. this round you savored each piercing individually. you spent long moments licking and sucking on the third barbell, then the fourth, humming so the vibrations traveled through the metal straight into his nerves. heeseung was deep in subspace now— whiny, pliant, and vocal.

“your tongue feels so perfect on them every flick makes my brain melt i love being like this for you just your needy boy.”

you edged him for what felt like forever — bringing him close, then pulling back to kiss his thighs or lick slowly along the sides. every time you returned to the ladder, his reactions grew stronger.

when you finally took him all the way down again, nose pressed to his pelvis so every single piercing rested against your tongue at once, and swallowed repeatedly, massaging them all together, heeseung broke.

“fuck— yes— im close again— please let me cum in your mouth i’ll be so good—”

his second orgasm crashed through him even harder. he cried out your name, back arching off the bed, hips stuttering as he spilled down your throat once more. tears slipped down his temples from the intensity.

you kept him in your mouth through the aftershocks, licking softly until he was trembling and whimpering. then you climbed into his lap. heeseung immediately wrapped his arms around you, burying his flushed face in your neck, clinging tightly.

“im sorry I’m such a quick shot,” he mumbled shyly against your skin. “the piercings make everything feel ten times stronger but I love how you take care of me.”

you stroked his hair and kissed his temple. “you’re perfect like this so pretty and whiny when you fall apart.” after twenty minutes of soft cuddling, whispered talk about classes, and gentle touches, he grew hard again between your bodies. he peeked up at you, eyes needy and hopeful.

“can we do one more round?” he asked softly. “I want to feel your tongue on every barbell again please?”

you kissed him deeply and slid back down between his legs. this final round was the most intense and drawn out yet.

you worshipped his jacob’s ladder with absolute focus — long, wet licks up and down the entire row, sucking on each individual barbell until he was shaking, flicking them rapidly, then pressing them firmly with the flat of your tongue.

you deepthroated him repeatedly, letting the full length of the ladder slide over your tongue while you swallowed and hummed. heeseung was a complete mess — sweaty, voice hoarse from moaning, tears of pleasure streaming down his face as he begged incoherently.

“please— your tongue on the top one again— im so close— I need it— im yours, just yours—”

when you finally let him cum the third time, focusing hard on that uppermost piercing while stroking him firmly, heeseung came with a wrecked, sobbing moan. his body went limp, cock twitching weakly as the last pulses spilled over your tongue.

you cleaned him gently with soft licks, then climbed up to hold him. heeseung curled into you immediately, nuzzling against your chest, pressing lazy kisses wherever he could reach.

“thank you,” he whispered, voice completely raw. “for being my friend for this for knowing exactly how to make me lose my mind. I don’t know what I’d do without our nights like this.”

you stayed tangled together in his small bed, the scattered textbooks long forgotten on the floor. the campus outside remained peacefully unaware of how beautifully your favorite submissive friend fell apart — whiny, sensitive, and completely yours behind closed doors.

01 GENERAL HEADCANONS

college!luke would go to a college far away from his hometown; i think he would prefer to go to a college in a city even though he hates how busy it is 24/7. the noise becomes the calm to him.

i think he'd either be a computer science major, an international relations major, or a management major. it is genuinely just from the vibe he gives off (and also his interests/talents).

we have established as a community that luke castellan is a fratboy so of course i had to mention it again!

i don't think he'd be the type to sleep in class, but i do think he'd skip classes from time to time just because he can and he already read up on the lesson for that class, so why go?

i think he'd be into collegiate debate. we all know that canon luke literally fought for his ideals and to be heard by those who oppose him, so he would definitely thrive in debate tourneys.

aside from debate, luke is also the type to be part of student council. he has good leadership skills and manages stuff well and responsibly; i think this is just his after-school environment.

if not student council, i think he'd be the head of certain projects going on in his organizations.

luke is the type to randomly crash into his friends' dorms / condominiums during the day when he has free periods. sure, he has his frat house, but why would he pass on the opportunity to bother his dear friends?

he hates seeing student vloggers on campus. he sees a lot of them around, recording with their cameras or their phones while walking across campus or sometimes even in spaces like the library. it irks him that he can't have peace in his campus sometimes because as much as he loves attention, he'd rather not have his face recorded in the background and posted online.

frequent frat party attender!

despite that though, i believe he also frequents the campus library and coffee shops to study. he allots an ample amount of time to get his readings & assignments done before he goes off to party.

during group works, luke would always unconsciously assert himself as the group leader, trying to task with everyone and ask for updates.

he recites a lot during class; he doesn't get conscious about how many times he had risen his hand either, he just wants to yap about the topic!

has a solid friend group that have been together since freshmen year (they broke the freshmen fg curse!). i think luke likes to keep his inner circle small and tight even if he knows a lot of people.

frequently suggests to go to the beach or to an amusement park during summer breaks

02 SFW HEADCANONS

you and college!luke have actually met a lot of times on campus, but you never really fully acknowledged each other outside of normal interactions.

you saw each other in the student council room, during debate training, and were even classmates during one of your required core classes (it was math, you both struggled...)

however, you guys weren't properly linked until a frat party—his own's!

contrary to popular belief (on fratboys), luke actually eases into the relationship slowly; he doesn't force it.

he took you out on three dates before he even tried to make a proper move like holding your hand; despite it all, he really is just a loser.

he's (obviously) the one who asks you to be his girlfriend, but he phrased it as: can i be your boyfriend? because he wants to be yours oh so bad...

he had his frat brothers help him set up a picnic for the two of you!

ok dating college!luke meant receiving flowers very often. at your dorm, during your first class of the day, when you guys have date nights. it doesn't matter! he will always bring you your favorite flowers, but he always makes sure that they're a different bouquet/assortment.

he is clingy as fuck. he can't go a day without cuddling with you, or kissing your neck or lips, or holding your hand. its safe to say that luke loves having you over at the frat house and would even walk you to class the next morning. HE LOVES INTERTWINING HIS FINGERS W YOURS !!!

he loves it when you wear his hoodies (especially to class!) it makes him feel like he's with you

you guys have frequent study dates that were either a) his proposals or b) a compromise bc you need to study but he won't leave you alone

most people believe luke castellan to be nonchalant, but no he is actually just as much of a yapper. when you guys go on dates or spend your vacant periods together, luke talks nonstop about the events happening within his clubs / frat, and often complains about the work he has to do too.

of course he never forgets to ask about your day too !!! in fact, knowing about your day is one of the highlights of his own.

i mentioned he was clingy, but he also just loves kissing you and that's a separate thing. he loves kissing your face / cheeks, your fingers, your knuckles, your neck, and your shoulder (anywhere honestly! as long as its you). luke tends to do it when he's especially stressed with school work and / or touch starved because he was unable to see you as often as he usually does.

college!luke loves hugging you from behind. since you guys are in a big campus and don't expect to see each other at all times, there have been multiple times where he sneaks up behind you and hugs you from the back. he doesn't let you go!

03 NSFW HEADCANONS

college!luke has a very high sex drive. with the college stress, plus his own internal issues, plus a really hot gf? yeah, he is very motivated to say the least. so, don't be surprised when you're simply lounging in your dorm, relaxing, watching an episode of your favorite show, and he suddenly barges into the room asking to cuddle with you! next think yk, your clothes are on the floor and he's right on top of you.

he's usually the dominant one, but he doesn't shy away from subbing for you, especially if you ask him to. one simple "can i be on top this time?" and he's already lying down for you.

when he's the sub, he is very, very whiny. if you stop bouncing on him and cockblock him? he's gone. he'll whine, thrash, and pout at you to let him cum. he'll even whine when you pull away from a long, hot makeout session that he did not intend to end so abruptly.

when he's the dom, he could go either rough or gentle, depending on the mood.

if he's stressed, riled up, or maybe even jealous? he'll have you in a mating press for hours on end, thrusting into you with fervor while kissing your lips until they're swollen. he'll cum in you a few times, too (only if you tell him you're on the pill though!). he'll look at your disheveled face while fucking into you, "fuck, you feel me inside you? can anyone else make you feel this good? didn't think so."

if he's feeling sensual; maybe he misses you, or he just wants to show you how much he truly loves you (or wants to worship you), he'll go slow. luke would take his time trying to make you feel special, and this is usually when he eats you out the most! that would be followed with slow yet hard thrusts filled with intent. "i love you, my pretty girl—a-ah, fuck you feel so good around me."

speaking of eating you out, college!luke is the sweetest munch ever! he isn't the biggest fan of p in v quickies, but he would never turn down eating you out for a quick 5 minutes. it could be a break in between your classes, and he'll have you sprawled on your bed, whining and mewling while he carefully eats you out. "pretty pussy... god, you taste so good, babe."

he gets hard from just eating you out too.

college!luke is a tits guy. he loves massaging your breasts when you guys are cuddling or when he's eating you out. he'd play with and pinch your nipples before sucking on them as if they'd draw milk. then he'd leave hickeys all over them. sometimes, he'd just squeeze them or hold them when you two are alone together (and ofc you let him). he does all of this while looking straight at you with his big, gorgeous, brown doe eyes like you're the most beautiful thing he'd ever laid his eyes on (you are). its a way of worshipping you (at least to him). "so soft, babe..."

college!luke who loves giving and receiving hickeys. the two of you would be making out, you on top of him, straddling his lap, and he'd suddenly break away from the kiss just to start attacking your neck. he'd suck very slowly, relishing the taste and softness of your skin before he leaves the red spot, licking and kissing it. then he'll plant another, then another one, then another one...

he particularly leaves a lot of hickeys when he gets jealous. maybe he saw you talking to some guy, maybe one tried to flirt with you. doesn't matter. he'll leave angry red and purple marks all over your neck and chest, whispering "mine" after every single one.

sometimes, you're the one who gives him hickeys, and he absolutely basks in it. he'll tilt his head a lot more to give you room and would whine or groan when you sucked hard on a spot.

college!luke who adores fingering you. he usually does it when you guys are lying down, cuddling. his hand would snake its way down, and when you don't stop him, he'll continue down to massage your pussy. he'd circle your clit while he kisses your neck, then he'd dip down your folds and let two fingers enter your hole. the cute noises you make motivate him further until you eventually cum on his fingers.

he licks his fingers clean before kissing you!

college!luke who loves it when he knows you're wearing lingerie on beneath your clothes. it turns him on that he knows what's going on under there whereas nobody else does. it gets him giddy thinking that he'll be taking your clothes off later to reap his reward.

college!luke who doesn't care if you wear anything too revealing in public. he'll even show you off! just know that when you guys get home (either to your dorm or his frat house), you'll be down for a good fuck.

he loves it when you wear his clothes. they look bigger on you yet it genuinely gets him hard. same goes when your perfume stays on his clothes. just the sight (or smell) of you turns him on he is that down bad.
