asking the boy you’ve known nearly your entire life to teach you how to have sex isn’t weird, right...? right?

caleb has taught you a lot of things over the years.

he taught you how to drive a car in the shopping mall’s parking lot, how to cheat at card games, how to avoid burning the house down by letting him cook for you instead, how to sneak underneath the turnstiles on the subway to avoid fees.

he’s reliable and sturdy and a little reckless, but also patient and nonjudgmental— creating the idea in your idea that he’s kind of all-knowing, that whenever you don’t know something caleb does, that whenever you need help, you turn to no one else but him. which is precisely why you’re standing outside the door of his bedroom right now, hand lifted to knock on it.

because surely, asking caleb to teach you how to give a blowjob falls somewhere underneath that category too, right?

it’s one of those rare moments when the two of you are off work at the same time. caleb, on annual leave for the next two weeks and you, taking out a handful of unused vacation days to spend time with your favorite person in the world. it’s like old times again, when you can simply walk down the hall and hear his laugh drifting from underneath the door as he plays some stupid video game with college buddies.

thinking of the old days is exactly why you’re hesitating at the door. there’s too much shared history between the two of you, too much to lose if this goes badly, if you’ve been reading him wrong all along and he doesn’t want the same thing. there’s no way you can march in there and ask the boy you were raised with teach you how to—

“door’s open, pipsqueak,” caleb calls, somehow knowing you’re there because of course he does. you used to complain that he must’ve secretly implanted a tracker in your arm because he always knows your whereabouts, which made games like hide and seek with him impossible.

knowing it’s too late to play it off, you walk inside his room, greeted by his devastatingly gorgeous grin. “hey, you. lemme guess— the fridge is empty? no? lightbulb in your room need changing again? huh… or did you just miss me?”

“uh,” you mumble, shifting your toes in the soft carpet of the rug in the middle of his room. “not exactly. i was just wondering if you had time to talk and— … you’re not wearing a shirt.”

you realize how dumb you sound as you point it out, it’s just that your brain short-circuits, turning into a syrupy mess at the sight of caleb without a shirt on, his dog tags resting against bare skin. you’ve seen him like this before, of course— but not since he up and left, gallivanting off into the world to become a hotshot military pilot.

he’s always been nice to look at when you think he isn’t paying attention, but god he’s pretty. your eyes blink almost in disbelief as you take in his broad, muscular form that did not exist while he was a cadet in basic training. your gaze can’t help but snag on the ripple of his abs, or the thatch of brown hair trailing from his navel to disappear beneath his gray sweats. he swivels in his stupid gaming chair, smiling at you with his stupid face—

“uh, yeah?” caleb laughs, forehead creasing in confusion like you shouldn’t be surprised and really, you shouldn’t. caleb is like a furnace, blood running hot even in the middle of winter. “gran’s got the heat turned up to max again. it’s like she wants to kill me.”

“yeah, right,” you shake your head, laughing skittishly. “sorry. i’ve got a fan you can borrow, if you want.”

“thanks,” he says, magenta eyes dragging over your form suspiciously, taking in the way you’re standing in the middle of his room fidgeting like a leaf in the wind, hands white-knuckling the hem of the oversized shirt you’re wearing, knees knocking together all nervous and cute. he frowns, leaning forward with his elbows on his knees to give you his full attention in that heart-stuttering way he often does.

“what’s with you? not that i’m not glad to see you, but… did something happen? did someone do something to you?”

“no, no— nothing like that,” you hurry to reassure, voice cracking on the last word as your cheeks begin to burn in embarrassment, trying to find the words to say what you need to without crashing and burning. swallowing around a lump in your throat, you glance at the paused screen of caleb’s game before blurting out—

“can you teach me how to give a blowjob?”

caleb immediately chokes.

a lesson on what not to do.

the overclocked fans on caleb’s gaming rig whirs in a soft hum, the neon lights in his room flickering crimson streaks over his handsome face in the dark. he wonders if it’s post traumatic stress or prolonged exposure to cosmic radiation in the sky forcing him to hallucinate. obviously, he’s got too many marbles in one jar and not enough in the other because there is no way he’s heard you correctly.

slowly, he removes his headset. “come again?”

“i’m awful at it, ge,” you exclaim, throwing your hands up in exasperation. in fact, you don’t know if you’re awful at it or not because you’ve never tried. you’ve been too busy waiting on the man in front of you to stop torturing you both, but caleb doesn’t need to know that. “you see, i’m dating this guy, right? and we’ve been hitting it off well. i can tell he wants to take it to the next level, but i’ve never… and you— you’re good at everything, so i just thought…”

“thought i would give you lessons,” he finishes for you, his voice deepening to a rougher edge that makes you shiver. “so you can suck your boyfriend better. do i have it right?”

“y-yeah…”

“since when do you even have a boyfriend? you didn’t tell me anything,” he says, doing nothing to mask the disappointment in his voice.

“uh, we’ve… been seeing each other for a couple of weeks?” you fumble, shifting from foot to foot uncomfortably. “i didn’t want to say anything yet. in case it didn’t work out.”

“so you want to learn how to suck dick for a guy you’ve known for a couple of weeks?” he counters, a muscle in his jaw twitching. he’s got no right to feel jealousy, not when he’s wasted so much time attempting to be one thing in your life when you clearly wanted something else. he’s got no right, but the thought of you on your knees for someone else, someone that isn’t him, makes his blood boil enough that he already knows what his answer will be.

however, you’re already backing up towards the door, about to make a quick retreat. your plan was horrible, shame burning your skin like a brand. “what am i saying? oh my god, you’re right it’s stupid and wrong and gross. can we please just forget i even came in here—”

he lets you ramble for an excruciatingly long time, then he pushes out of his gaming chair and grins down at you like you just asked him to make a quick run to the convenience store. he stretches his arms above his head. “let’s do it.”

“w-what?”

you didn’t expect to get this far, honestly. you expected caleb to laugh at you, ruffle your hair, and call you ridiculous. but instead, he’s already striding to his door, thumb flicking the lock with a decisive click. when he turns, his expression makes your breath hitch— those unusual purple eyes molten, staring straight through you.

“first thing’s first, we need to lay down some ground rules, soldier,” caleb tells you playfully, stepping closer until your breasts brush against his midsection. his hand lifts, tucking a lock of hair behind your ear. “if you need to back out at any moment, you say so. no guy’s pleasure is worth your discomfort. and if i hear his name, whatever it is…” he pauses, eyes narrowing. “this stops. understood?”

you nod eagerly, fighting your smile as his scent envelopes you. he smells like spearmint gum, your shampoo that he’s been stealing since the two of you have been back at the house, and a hint of sweat from the stifling air in the room.

“use your words, pipsqueak.”

“y-yeah, i get it.”

his smirk is all teeth. “good girl.”

caleb guides you over to his bed, sitting down on the edge. his big hands reach for you, circling your hips and pulling you towards him until you’re standing in between his spread thighs.

“alright, my little student,” he jokes. “you wanna get him all riled up before the main event so start with something small like… a kiss,” he murmurs, eyes lifting to glance at your mouth as his finger traces the hinge of your jaw. “you do know how to kiss, don’t you?”

“of course i know how to kiss,” you grumble.

caleb nods and then curls his hand around the nape of your neck, pulling you down to his level. you lean with the pressure, slotting your hands in the junction between his neck and shoulder, sliding them up until you cup the underside of his jaw. then, you’re kissing him— kissing caleb, the boy who used to patch up your scraped knees with cute band-aids, who let you crawl into his bed after nightmares, who pretends he hasn’t thought about kissing you, about making you his, for years.

the kiss is messy, desperate and hungry, decades of pent up feelings behind it. a string of saliva keeps your mouths linked together whenever you pull back for air and when caleb’s tongue swipes across your bottom lip, you whimper and part your lips to let him in, body melting against his front until your weight’s toppling him back onto his elbows, hitching your leg over his waist to crawl on top of him.

his grip on your waist tightens, gently pushing you to stand once more. “this is feeling less like a lesson, and more like you just wanting to do this with me,” he teases, making heat flare across your cheeks.

caleb guides your hand to the waistband of his sweatpants, the heat radiating through the fabric searing your palm. breath hitching, you begin to sink to the floor in front of him but his hand shoots out to stop your descent with a breathy laugh. “no no no, c’mere. you’re gonna hurt your knees down there.”

backing up, he moves until he’s lounging against the headboard, impossibly long legs stretched out on either side of your sweet figure.

“still wanna do this?” he asks, lifting a brow. when you nod, he continues to speak, voice gravelly, “take it out then.”

your fingers fumble with the drawstring a bit, struggling to undo the military knot caleb’s tied there, but you manage eventually. peeling back the waistband of his sweatpants to free his cock.

you should’ve known it would be just as pretty as the rest of him— it’s the biggest one (the only one) you’ve seen in person. he’s thicker than he is long, flushed dusky pink with veins that make your cunt clench with the desperate need to feel them dragging along your inner walls. his adam’s apple bobs as he swallows, watching you reach for it, nearly sobbing when your hand wraps around him.

“fuck—!” his hips jerk and stutter in shock, hand shoving yours away with a quickness. you frown and bite your lip, retracting your grip as if you’ve been burned.

“oh no,” you rush out, moving back to sit on top of your hands like a scolded kindergartener. “did i do something bad? did i hurt you, cal?”

caleb’s chest heaves, breath punching out of his lungs rapidly, eyes squeezed shut as he tries to slow the speed of his heart down. he’s dreamt about you touching him like this for ages, and the image of your dainty hand nervously wrapping around his cock will be seared into his brain for the rest of his life. you crawl back towards him slowly, seriously worried. “caleb?”

“i’m fine, pip,” he sucks in another breath, then opens his eyes to look at you. “didn’t mean to scare you. you didn’t do anything bad, you just surprised me. go ahead, touch me again.”

“if you’re sure,” you mumble, then hesitantly circle your fingers around caleb’s shaft again. he’s ready for it this time, hot against your palm when you give him an experimental squeeze, making caleb hiss through clenched teeth. “how’s that?”

“a bit tighter,” he instructs, palm closing over yours to adjust your grip. you squeeze him tight, and the hitch of his breath makes you squirm, stickiness gathering between your thighs at the sound. “don’t just squeeze, guys like it when you stroke. base to tip— no, don’t yank it like a fucking joystick, pip. god.”

his protest makes you burst out in giggles before caleb is shushing you with a severe look, his purple eyes narrowed. sucking your plump lower lip in between your teeth to keep from smiling, you nod at him with an exaggeratedly focused look.

“wet your palm,” he tells you, rolling his eyes at your wrinkled nose. “getting a handjob from a dry hand hurts, it’s like sandpaper.”

“are you saying i have dry hands, caleb? i moisturize daily, unlike you,” you whine out, but you listen to him anyway— you’re a good student, after all, and you don’t want to do anything that’ll make caleb want to stop. you lick your palm a few times, eyes on caleb the entire time.

the next time you touch him is with a spit-slicked grip, dragging your hand up and down his cock in an inexperienced, sloppy rub that should feel uncomfortable, but caleb eats it up— hips jerking involuntarily, pearls of watery precum already beginning to leak from the slit of his cock. your gaze is transfixed on it, a little greedy too, watching it stain your knuckles with each stroke.

it’s that same greediness that makes you lean down and brush your lips against the head of his cock, cherry tongue lolling out to tentatively taste the salt-bitter precum beading there. caleb’s hips immediately kick upward in a desperate twitch, but he forces them still, knuckles ashen where they reach down to grip the sheets.

“easy,” he rasps, voice fraying at the edges. his thumb strokes your cheek briefly. “just the tip first, okay? don’t go trying to swallow me down or anything.”

you do what he’s taught you so far; flatten your tongue, swirl it around the head— like that, fuck— press it hard against the thick, sensitive vein running along caleb’s underside, then repeat. every time, you’re rewarded with caleb brushing your hair back, murmuring soft praises, or your personal favorite— his deep, almost nasal groan, the hard planes of his abdomen flexing underneath the heady heat of your tongue.

it’s intoxicating, watching him fall apart like this— exactly what you wanted when you walked into his room. you want to pass his class with honors, please him even more, so you drop your mouth open a little more and suck him in deeper.

too deep.

the thick ridge of his head nudges against your uvula, tears springing to your eyes almost immediately. little startled chokes cough from your throat as you pull off caleb’s cock, bands of saliva stringing from his tip to your mouth in a way that should be gross, but you don’t care one bit, too busy trying to catch your breath.

“shh, shh— breathe,” caleb soothes, eyes darkening with something perilously close to reverence and pride. “through your nose, slowly. you can’t force it, that’s why you keep choking. when you’re ready, try again.”

you let caleb thumb away your tears like he’s done countless times before and when you’re ready, when you’ve had enough air to breathe, you let him guide you back onto his damp cock. eager, swollen lips bringing him in against your cheeks in a hot, branding suction that twists his insides up.

he’s supposed to be teaching you, showing you the ropes so you can please your stupid boyfriend, but you barely even need it— god, you’re so good at this without even trying. how can he focus on teaching when he��s got all of his focus pointed towards trying not to shoot his load down the back of your throat like some inconsiderate asshole?

he can barely look down at you because every time he does, your teary eyes glance up at him through thick lashes with an expression that begs for praise. he knows if you didn’t have a mouth stuffed full of his cock, you’d be asking him am i doing it right, ge?

his thighs tremble, eyes lidded as you finally find a steady pace— mouth bobbing up and down, spit bubbling at the base of his cock where you’re starting to make a mess on him.

and when your hands dip down into his sweatpants, cupping his balls in your soft hand, caleb’s vision whites out, his climax rushing to the front at a rapid pace. before he can cum, though, he takes two fingers and pushes at your forehead, hauling you off his cock with a wet slurp. his chest heaves, dripping beads of sweat that glow in the haze of the neon lighting in his room.

he looks wrecked, and you fight your triumphant smile, schooling it into something unsure and pliant, batting your eyelashes. “did i… did i do it wrong?”

“fuck, no,” his chuckle is hoarse and ruined, calloused thumbs swiping spit from your chin as he gazes up at you meaningfully with those hooded eyes. “just don’t wanna cum down your throat.”

“o-oh.”

the implication makes arousal bubble low in your belly, thighs squeezing together in need. caleb tracks the movement, nostrils flaring as he grins knowingly. “yeah, you don’t want that either, do you, pipsqueak?”

for a while, the two of you just stare at each other in disbelief. you don’t know how to tell caleb that you’d take him in any form he’s offering himself in, pining after him long enough that it’s painful. nothing you ever did got his attention, not in the way you truly wanted. he’s protective and possessive in all the right ways, but he’d never make the first move.

he’ll never come out and admit that he wants to spread you out on his bed and fuck you dumb, mark you as his so nobody else can have you. it took you coming to him to even get this far, so you might as well take matters into your own hands once more.

“teach me the rest, ge?”

the rest.

caleb releases a pained groan at your words and you think he’s going to refuse you, but then he’s flipping your positions, pushing you down onto the mattress with ease. he makes quick work of his sweatpants, shoving them down the rest of the way. then, he wrestles your panties off your hips and tosses them somewhere across the room.

“look at you,” he whispers, pushing your shirt up— his cock leaking a bead of precum at the sight of your pretty tits. he reaches forward, toying with your puffy nipples, grinning at the sound of your soft whimper.

“c-caleb.”

“you drive me fuckin’ crazy, you get that?” the confession comes out sounding suspiciously like a whine. he gazes down at you like you’re water and he’s a man lost deep in the desert, dying of thirst. “you’re the prettiest girl in the whole wide world. look at these cute tits, just begging for me to touch them. and—”

his big hands sink into the fleshy part of your upper thighs, opening them to get his first exclusive look at your pussy. his thumb parts your folds, spreading one side apart to watch the way your entrance twitches. caleb dips one finger into your cunt and could fucking cry at how warm and tight you feel. “fuck, you’re so wet. is this all ’cause of me?”

“d-don’t look at it so shamelessly, you pervert,” you scold him, squirming back and forth in his hold as you try to snap your thighs shut. “stop teasing me or i’ll hit you. this is embarrassing!”

“why not?” he tilts his head, giving you that boyish grin that makes your heart stop. “after i’m done with you, it’ll be mine anyway. my pretty pussy. my girl.”

you huff and drive your fist into his shoulder before folding your arms over your breasts, lower lip stuck out in an unhappy pout. caleb winces, though mirth still shines amongst the nebulas in his eyes. he leans down to kiss your pout away, chuckling in amusement. “okay, okay, don’t hurt me. i’ll give you what you want.”

and then, he’s wrapping a hand around the base of himself, kissing your clit with the leaking tip of his cock before rubbing it up and down your slit. he coats himself in your wetness before he finally notches against your entrance and slowly pushes.

the pressure makes air stutter out of your chest, blunt and unyielding. he immediately notices your struggle and drops forward on his elbows, caging you safely in his embrace. he kisses the corners of your eyelids, licking away stray tears.

“i hate hurting you like this,” he whispers in your ear, hips drawing back and crawling forward again. you gasp, eyes falling shut, and he shushes you once more. slides a hand down to play with your clit to distract you, which only makes you clench up around him. his jaw is clenched tight enough to shatter the bone, hand fisted in the sheets next to your head. “shh— relax and let me in. it’ll feel good in a second.”

“i-i don’t know if i can,” you say, trying to force your body to accept him, but when he sinks in those first few inches, you whimper and dig your nails into his biceps. “y-you’re so big, gege.”

“f-fuck, don’t—” caleb grunts and his fingers grip the soft sides of your belly, holding your body to his like a lifeline. “don’t call me that right now. i might cum. i’m gonna put the rest in, okay? be a good girl for me and take it. i-i can’t wait any longer.”

he draws out and presses forward all the way in, burying himself to the hilt inside your sweet pussy. his gaze drops to where you’re split obscenely around him, cunt fluttering in protest at the stretch and a ragged groan tears from his throat. it takes every ounce of willpower the military beat into him not to cream himself right then and there.

“c-caleb!”

you whine as caleb retreats slightly, only to surge back in, fucking a little deeper this time. the weight of his cock stretching you out borders on cruel, but you would die before you ask him to stop, your walls squeezing him in a vice grip. it takes a few trials and errors (“keep your hips down, pipsqueak” and “i don't know, maybe a little to the l— fuck, right there oh my god”) but eventually, caleb builds up a good rhythm, the cool metal of his dog tags pooling in the valley of your breasts as he fucks you with deep, steady strokes; bottoming out each time with a guttural groan.

“fuck— stop clenching so much i’m gonna lose my mind,” his breath scalds your neck, teeth grazing your pulse as he fucks a little faster. “so fucking good. that’s it, baby. you’re doing so good. taking every inch of me like this.”

he’s right, it is so fucking good— no, it’s better. your nails scrape against caleb’s back. shivering at the hot pleasure singeing your nerve endings each time he fucks into you. it doesn’t take long for pressure to gather in your lower belly, a band waiting to snap.

you can’t help but wriggle a hand between the two of your bodies and circle a trembling middle finger around your swollen clit. “nngh, you feel so fucking good, cal.”

“a-are you- god, that’s so hot,” he grunts, glancing down at the way you’re toying with your clit and it turns him on so much he’s speeding up, cock pistoning in and out of you, his thrusts deepening until he’s nearly kissing your cervix, he’s in so deep, your thighs slamming against his hips as you try to close your legs when the head of his cock brushes right up against your sweet spot, creating starbursts behind your eyelids.

“oh god, cal— i-i can’t!”

caleb’s grin is feral, grinding deep to press into that swollen spot inside you relentlessly. “knew i’d find it,” then his fingers joining yours and it’s so much better than your own, two digits rubbing quick circles into your sensitive clit. you’re a babbling mess at this point, the pleasure too much to keep up with. “can you cum for me? can you let me feel it? please? i’ll never ask you for another thing if you give me one right here, right now.”

what are you supposed to do, deny him? you couldn’t even if you tried, not with the heat in your belly full to bursting, needing an escape.

“’m gonna c-cum for you, ge, just for you,” you sob.

caleb has seen many versions of you over the years— grumpy and pillow-marked in the morning with syrup stains on your shirt at the breakfast table, covered in sand and sun-kissed at the beach, screaming at him to do something about the jellyfish sting on your leg, in sleek black dresses at the military balls you attended as his plus one that made all his comrades stop and stare. but you’ve never looked prettier than you do right now. his dog tags between your breasts, your creamy pussy fluttering around his cock, and your pretty face twisted in pleasure as you’re about to cum for him.

he hopes that when he dies, he’ll go out with this image in his brain.

those big doe eyes of yours roll back into your head, hands frantically pushing at his abdomen as if he’s trying to escape the overwhelming friction of his cock. you cum hard, thighs trembling, vision winking out. wet droplets of tears stream down your cheeks as white heat washes over your body, the pleasure bleeding through your limbs like wildfire.

seeing you like this, what is caleb supposed to do? not follow you? he’s been holding his own orgasm back since you barged into his room in one of his shirts, begging to be taught how to suck a cock. there’s no way he can last through seeing— through feeling— you cum around him. his rhythm fractures almost immediately and he knows he’s on thin ice, fraying at the edges.

“gonna cum,” he grits out, voice mangled. “fuck, i’m gonna cum. where do you want it?”

you don’t waste a second, babbling out the answer desperately, “i-inside, ge, cum inside me. give it to me please i want it so bad i’ll do anything!”

that’s all it takes.

one more sloppy thrust and he cums right after you, his hands gripping your hips hard enough to bruise, holding you still. he breathes choppy, ruined moans into your neck as he pumps his release deep inside your cunt before he collapses against you, damp chest heaving against yours, giving a few more weak thrusts of his hips as his climax ebbs.

you don’t know how long the two of you lay there, struggling to catch your breaths. you’re satisfied and pliant as putty underneath caleb, unable to move from his heavy embrace. he’s a wall of solid muscle, one that is pressing you into the mattress. “caleb, you’re heavy.”

“gimme a minute here, pipsqueak,” caleb chuckles breathlessly against your sweaty skin, pressing a wet kiss to your neck. “i just had the best sex of my life and can’t catch my breath.”

you begin to smile in pride, but then your eyes narrow as his words register through the fucked out haze clouding your brain. “wait, you were having sex before this?” you ask, jealousy bubbling up in your chest. “was it that one sergeant? the one who kept giving you lovey dovey eyes at the DAA gala?”

“mmm, nope,” he answers almost immediately, kissing your lips quickly to placate you, making your heart swell big and bright for the boy on top of you. “chill. saved myself all this time for you.”

your heart begins racing stupidly fast at that. “sap,” you tease, before an idea pops in your head and you reach for your phone tossed haphazardly on caleb’s bedside table.

caleb’s grip on you tightens as he notices you reach for it, a dark cloud shuttering his loving expression. “what are you doing?” he demands, the venom in his tone startling you a bit. “texting him already? that eager to try out what i just taught you?”

you frown in confusion until you remember the excuse you used upon coming into caleb’s room. wow, the boy you’re in love with is an idiot. giggling, you lean up and press a sweet kiss to his cheek before opening the camera on your phone and snapping a quick selfie of the two of you.

“no, you big dummy, i’m taking a pic of us losing our virginities together so i can add it to our photo album,” you explain simply, grinning. “and there was never any boyfriend, i made him up.”
