a tall, broad-shouldered, bespectacled mess who tries so hard not to stare when you walk out of the shower with just a towel slung around your waist.
jake is in his usual corner — completely hunched over his desk, noise-canceling headphones pushed back, hoodie sleeves rolled up to the elbows as he types frantically on his laptop. glasses fogged slightly. cheeks red. you pretend not to notice how quickly he snaps his gaze back to the screen when he sees you.
but you do notice. you always do.
he’s been like this since the start of the semester. nerdy. awkward. painfully polite. so uptight you could probably bounce a coin off his clenched ass if you tried. he’s got this huge brain, top of every single class, straight-laced lab ta vibes… and zero experience with actual people. especially not when it comes to you.
and jake is obsessed with you. not in a creepy way. well, not really. but it’s there — the way his breath catches when your hands brush, how his gaze lingers on your mouth when you laugh, how he gets impossibly quiet whenever you’re shirtless. you could tease him about it. maybe you should’ve. but the thing is… it’s cute.
even now, typing some ungodly long report, he’s chewing the inside of his cheek, one foot tapping nervously. his sweatpants are pulled tight over thick thighs, and the outline of his cock — long, half-hard, resting toward his left leg — is dangerously obvious. jake doesn’t even notice. or maybe he does.
you cross the room slowly, towel still low on your hips, hair damp, skin warm from the steam of the shower. jake stiffens when you approach, pretending to still focus on whatever he was doing on his laptop.
“hey, jakey,” you say, leaning over his chair just enough to let your voice graze his ear. “whatcha working on?”
he turns slightly, eyes wide behind thick glasses.
“o-oh. just a—uh—coding lab. neural network simulation. i’m, um, adjusting the weight—of—” his voice catches when your fingers brush his shoulder. “—of the bias layers to fit the parameters.”
“i have no idea what any of that means.”
jake lets out a nervous laugh, way too quick and too high to hide his tension.
he looks up at you. his lips part, like he wants to say something else. you watch his throat bob as he swallows.
you tilt your head, your smile softening. “you good?”
jake’s eyes drop to your chest, then quickly dips lower before snapping back to your face.
“yeah. i mean. y-yeah. totally good. fine. great.”
“you sure?” you lean in a little more. you can literally feel the heat coming off his face. “you’ve been acting kinda weird lately.”
jake bites his lip. then, all at once, he blurts it out.
“i think about you when i—when i touch myself.”
the silence in the room stretches for a second too long.
his eyes go round. “shit. i didn’t—i wasn’t—i didn’t mean to say that. forget it. forget i said anything, oh my god—”
but your hand closes gently over his shoulder, grounding him. your voice is low, even. “jake.”
“jake,” you say again, firmer. “look at me.”
he does — slowly. his cheeks are blazing, lips trembling a little, but his eyes finally meet yours. and fuck. he looks so vulnerable. so desperate. so hot.
you step between his legs, and his breath hitches. jake sits completely still, as if paralyzed. you run a hand through your damp hair, then let the towel slip an inch lower, just to see what he’ll do.
jake’s pupils are blown wide.
“you think about me?” you ask. “when you’re alone?”
his voice is barely audible. “all the time.”
“yeah?” you glance down, and sure enough, the bulge in his sweatpants is fully hard now, pushing up toward his waistband. “you do more than think, huh?”
jake’s breath comes quick. “i—i’ve never…”
that makes you pause. “never?”
“i’m a virgin,” he says, voice cracking. “i’ve never done anything with anyone. i j-just… i always wanted it to be you. i know that sounds s-stupid—fuck—it’s so stupid—”
you lean down, whisper close to his ear. “no, jake. it’s so fucking hot.”
the sound he makes is somewhere between a gasp and a whimper. his hands curl into the sides of his chair, knuckles white. you place a hand on his knee and feel how tense he is — trembling, barely keeping it together.
“i’ve wanted to do this for a while,” you murmur. “but i didn’t want to push. didn’t know if you could handle it.”
jake lets out a shaky laugh. “i-i don’t think i can. i think i might cum if you just keep talking.”
you smirk. “that’s kinda the point.”
you slowly kneel between his legs, eyes locked on his, and rest your palms on his thighs. the heat coming off him is absolutely insane. his breath is ragged, chest rising and falling in shallow bursts.
“can i?” you ask, voice soft but deliberate. “touch you?”
jake nods so fast it’s almost funny.
“please. please touch me.”
you reach for the waistband of his sweatpants with deliberate slowness. he lifts his hips obediently, eager, desperate. and when you pull them down…
he’s big. like, obscenely big. so long, so thick, so veiny, flushed red at the tip and already leaking.
no wonder he’s been so pent up. that thing must be a curse and a blessing all in one. and the way he looks down at you with his eyes wide open, lips parted, hair a little messy — it’s like he’s waiting for a miracle.
“oh my god, jake,” you mutter, wrapping your hand around the base. he shudders. “how do you even walk around with this thing?”
jake groans, head falling back slightly. “d-don’t—don’t say stuff like that.”
you stroke once, slowly, and jake’s hips jerk. his hands fly to grip the arms of his chair, and his mouth falls open with the prettiest little moan.
“f-fuck—your hand feels so good—oh my god—”
you lean in, licking a stripe from base to tip. his entire body jerks.
“gonna show you what it really feels like,” you murmur, voice low, just before your lips close around the head.
jake completely loses it.
the moan that rips out of him is completely unfiltered, like it tears straight from his chest. his hips try to buck up into your mouth, but your hands are already gripping his thighs, holding him down. his cock twitches against your tongue — thick, pulsing, leaking steadily.
you take him deeper, inch by inch, but there’s no way you’re fitting all of it. he’s just too big. your jaw is already straining, lips stretched wide around him, and you’ve barely taken half before your throat tightens.
jake looks down, panicked, breathless.
“wait—shit—are you okay? d-does it hurt? i didn’t mean—fuck—you don’t have to—”
you pull off just long enough to pant, “jake. shut up.”
and you swallow him again. just as much as you can take.
the sounds coming out of him are filthy — desperate little whimpers and stuttered gasps. one of his hands leaves the armrest and shakily touches your hair, like he’s afraid to grip too hard. you glance up, and the look on his face is wrecked — glasses slipping down, mouth open, pupils blown wide with awe.
“holy shit—you look so good—fuck, you’re perfect—your mouth is so warm—i c-can’t believe this is happening—”
you hum around him, and the vibration makes his thighs jerk under your hands. you start to stroke what your mouth can’t reach, twisting your wrist just right, and he chokes on another moan.
“you’re gonna kill me,” he babbles, voice cracking. “i’m—i’m so serious, i’ve imagined this so many times, but this is—this is better—s-so much better—fuck, your lips—your tongue—”
you swirl your tongue around the head again, tasting the salty smear of pre-cum. he’s leaking like crazy now, and you swallow greedily, giving him soft, wet, messy kisses along the underside.
“i’m not gonna last,” he gasps. “i’m—i can’t—i’m sorry—i c-can’t—”
his voice is pitched high, barely hanging on. you glance up again, letting saliva drip down your chin, and damn, he’s so close. his abs are trembling, cock twitching against your tongue, flushed all the way to his ears. you want to break him. you want to watch him fall apart.
you tighten your grip, suck hard around the head, and murmur, “do it. cum for me, jake.”
he makes a choked sound — somewhere between a sob and a scream — and then he’s spilling into your mouth with a full-body shudder.
“f-fuck—oh god—i’m cumming—i’m—fuck—”
it’s so much. hot, thick spurts fill your mouth before you can even register it. you moan around him, swallowing everything he gives you, and jake completely falls apart — trembling, panting, babbling nonsense.
“oh my god—you swallowed—you’re swallowing—fuck—i didn’t mean—i didn’t even warn you—i—”
you pull off with a wet pop, wipe your mouth with the back of your hand, then look him right in the eyes as you swallow the last of it. his pupils dilate like he’s never seen anything sexier in his life.
“i can’t believe you just did that,” he murmur, completely shell-shocked. “you’re insane. you’re—oh my god.”
you lean up, straddling his lap before he can fully catch his breath. his dick twitches against your stomach, still half-hard despite just blowing his load.
“you okay?” you ask, brushing sweaty strands from his forehead.
jake nods, lips parted. “y-yeah. i mean—no. i think i’m dead. this is heaven, right?”
you just grin and answer with a kiss.
his lips are hot and soft, pliant under yours. you press in, firm and hungry, and jake kisses back like he’s starving. his hands finally grip your waist, fingers trembling, and he moans into your mouth — low and needy.
he can taste himself on your tongue. you know he can. his whole body stiffens, but he doesn’t pull away. no — if anything, he kisses you deeper, hungrier, desperate to keep feeling you, to stay in this moment.
you roll your hips against him gently, and he whines into your mouth.
“you taste so good,” you whisper against his lips. “so fucking good, jake.”
“i-i don’t deserve this,” he breathes. “you’re unreal. you’re like a—a dream. like a fantasy i made up in a lab. fuck. fuck. i—i wanna touch you. i wanna worship you—please, let me—”
you kiss him again, slower this time. letting him feel the weight of it. letting him breathe you in.
“you can,” you murmur. “you will. but not all at once.”
jake nods, dazed, lips kiss-swollen.
“y-yeah. i—i wanna make you feel good too. let me. please. i wanna—i wanna put my mouth on you. i wanna taste you like you tasted me. i’ll do anything—”
you chuckle softly, stroking his cheek. “we’ve got time. just relax. you’re not done yet.”
you glance down at his cock, already hardening again.
“yeah,” you say with a smirk. “oh.”
jake blinks up at you like you’ve rewritten the laws of physics in front of him. “i didn’t even know i could—fuck—how am i already hard again?”
you smirk, grinding down just enough to feel the heat of him against you. “maybe your stupidly huge cock has a mind of its own.”
he lets out a whine. an actual, honest-to-god whine.
“i—i want to be inside you,” he stammers, voice high and shaky. “i mean—only if you want that—i’ve never—i don’t know what i’m doing—but i want it. so bad. please.”
the desperation in his voice makes your chest throb.
you lean down, pressing your forehead to his. “i want it too. i want you, jake.”
he lets out a breathless little sound, like his brain short-circuited. “oh my god.”
you kiss him, slow and deep. then you’re standing up, tugging off your towel and walking backward toward the bed — eyes locked on his. he follows like he’s in a trance, sweatpants hanging low, hard cock bobbing heavy between his legs. he looks huge. almost too huge.
you crawl onto the bed, spreading your legs, resting back on your elbows.
jake stops at the edge of the mattress, frozen. his glasses are sliding down again, and he doesn’t even fix them.
“holy shit,” he whispers, staring. “you’re so perfect.”
you raise an eyebrow. “come here, jake.”
he climbs onto the bed — awkwardly at first, like he’s not sure where to put his hands — but when you guide him between your legs and pull him into another kiss, he melts instantly. moaning into your mouth, hips jerking forward just enough to make your breath hitch.
you reach between you, wrap a hand around his cock again, and fuck — he’s harder than before.
“you’re still gonna fit?” he asks breathlessly, as you swipe your thumb over the tip, smearing the pre-cum.
you grin. “you’re gonna make it fit.”
“we need lube,” he blurts, suddenly panicked. “oh god—i didn’t think—we can’t do this dry—i-i’m not gonna hurt you, i swear—”
you reach into the drawer beside the bed and toss him a bottle. “chill. i’ve done this before, remember?”
jake’s hands shake as he uncaps the bottle. “i’ve read about prep. like—i studied diagrams. online. but i’ve never actually—fuck, i’m so nervous—”
“jake,” you cut in gently, grabbing his wrist. “it’s okay. i’ll talk you through it.”
his eyes soften. “you’re so calm. so fucking sexy. you don’t even understand what you’re doing to me—”
“you’re literally about to fuck me,” you laugh. “so yeah, i think i do.”
he blushes hard, but doesn’t argue.
you spread your legs wider, curling your knees up a bit, and nod toward the bottle in his hand.
“fingers first. two to start.”
jake gulps. “y-yes. okay. got it.”
he slicks his fingers with more than enough lube, then settles between your legs again, eyes flicking between your face and your hole like he’s trying to memorize the physics of it.
you exhale slowly. “go on.”
the first touch is tentative — barely there, almost sacred. then one thick, slightly shaky finger pushes in, and the sound jake makes is not normal. it’s like his entire soul just left his body.
“you’re so tight,” he breathes. “warm—oh my god—you’re gripping me so hard already.”
“you’ve barely even started,” you whisper, lip caught between your teeth. “keep going.”
he nods furiously, slips another finger in, and starts working you open in slow, steady strokes. every movement is careful but needy — like he’s caught between worship and instinct. his glasses fog up again, and he doesn’t care.
“feels so good,” you murmur. “you’re doing perfect.”
jake groans. “i can’t believe this. your body—your sounds—i don’t know how i’m supposed to—function—”
you chuckle, then moan softly when his fingers curl just right. “you’re doing so good, jake.”
that literally ruins him.
“you can’t—say things like that,” he pants, lips brushing your jaw. “i’ll cum again just from hearing you say my name—fuck. i’m already—i need you.”
he pulls his fingers out slowly, lubes up his cock with a trembling hand, and lines himself up. the head of it is flushed dark, slick, huge, nudging against your hole.
“this might stretch,” you murmur, gripping the back of his neck, voice low and steady. “but i want it. i want you.”
jake’s eyes are locked on yours. “tell me if i go too fast.”
“just go slow. let me take you.”
the stretch is immediate. that wide head presses past your rim, thick and insistent, and your whole body tenses from the burn.
“f-fuck,” you groan slightly, head falling back. “god, you’re so big—jake—”
jake moans like he’s being electrocuted.
“you sound so hot. holy fuck—you’re taking me—you’re really—oh my god.”
he keeps pushing in, inch by inch, his jaw slack with awe.
“you feel—insane. so warm. so tight. you’re pulling me in like you were made just for me—”
your eyes flutter, breath catching with every slow, measured thrust deeper. “fuck. jake—feels so good—stretching me so wide—”
jake’s hips are trembling, his whole body braced as he finally bottoms out. fully inside you. deep and full.
“are you okay?” he whispers, staring at your face like you’re holy.
you nod, voice raw. “yeah. god, jake. you’re so big.”
jake lets out the prettiest, most pathetic moan you’ve ever heard — soft and high, like he’s trying not to cry from how overwhelmed he is.
“you look so good like this,” he pants. “you’re swallowing me—your hole is literally—fuck—i’m never gonna forget this. never.”
he pulls out halfway, then pushes back in slow. you gasp, nails dragging down his back. the friction, the pressure — it’s just so perfect.
and jake is completely gone.
“can’t believe i’m fucking you,” he babbles. “you’re so tight—so hot—i can feel your heartbeat around my cock—fuck. you’re clenching every time i talk—are you into this? are you into my voice? am i really doing it for you?”
“you’re doing so good,” you groan. “fucking me like it’s the only thing you’ve ever known—keep going—jake.”
he starts to thrust faster — not pounding, but with a rhythm that’s shockingly good for a first timer. deep, grinding, hitting the spot just right. your back arches, jaw dropping, and jake loses it.
“that sound—fuck, that sound you just made—do it again. please. please make that noise again—”
he buries his face against your neck, hips snapping harder now, cock dragging perfectly over your prostate with every stroke.
“your body’s unreal. you’re taking me so fucking well. you’re my dream. i could fuck you forever—oh my god—please let me.”
you kiss him, hard and open-mouthed, moaning into him as your legs lock around his waist and you grind up to meet his every thrust.
jake lets out a whimper — a genuine, needy sound — and does exactly what you ask.
he snaps his hips forward with a new kind of rhythm — rougher, deeper, completely fucking unhinged. his glasses are fogged, sliding halfway off his face, sweat clinging to his neck. he braces one hand next to your head, the other gripping your thigh as he drives into you like he’s trying to live inside your body.
“f-fuck, you feel so good,” jake pants, voice thin and wrecked. “taking me so well—how are you taking all of me—you’re fucking perfect—”
each thrust hits deep. you can feel the ridge of his cock drag over your prostate again and again, making your legs twitch uncontrollably around his waist.
and you can’t even talk. you can just moan — messy, choked sounds — and the second you do, jake nearly folds in half on top of you.
“those sounds—those fucking sounds,” he whines. “i c-can’t—i’m obsessed with them—please don’t stop—please keep making them—”
you claw at his back, eyes rolling, mouth open. “you’re so deep, jake—fuck—you’re splitting me open—”
he shudders. “say my name again. please. i’ll do anything. just—please—”
“jake,” you gasp. “jake, please, i’m gonna—fuck, i’m gonna cum—”
“inside,” he begs suddenly, voice cracking, desperate. “let me—please, please let me cum inside—i need it—i need it, oh my god—please, you feel so good—i wanna fill you up—i’ll be good—i’ll be so good—please—”
you nod, barely able to speak. “do it—do it, cum inside me, jake—”
with a broken moan, jake buries himself deep and cums, cock pulsing violently as he unloads inside you. the first spurt is hot and thick — then the second, and third — so much, it leaks out around him almost instantly.
your orgasm crashes into you a heartbeat later — explosive, blinding — you clamp around him and scream, your whole body shaking as you cum, crying out his name like it’s the only word you know.
“fuck—” jake cries, voice warping with the force of it. “you’re squeezing me—oh god—i can feel you—i felt your orgasm—you’re so fucking beautiful—holy shit—”
you’re both panting, soaked in sweat, bodies locked together. but jake doesn’t stop.
he keeps moving inside you with slow, shallow thrusts, overstimulated but helpless, still so hard inside you. his cock twitches again and again with every movement.
“i’m sorry—i can’t stop—i don’t wanna stop—you’re just—fuck, you’re milking me—i want to stay inside you forever—please—”
you’re crying. literally crying. you don’t even realize until jake kisses your cheek and tastes the salt.
“oh my god,” he whispers, pulling back just enough to look at you. his voice is all tremble and panic. “did i hurt you? are you okay? shit—shit, did i—”
“no,” you breathe, shaking, eyes still fluttering. “i’m okay. i’m just—jake—it was too good—fuck—”
jake cups your face, fingers trembling. “you cried from pleasure? holy fuck. that was me? i did that to you?”
you nod, half-laughing, half-gasping. “yeah. you did.”
and he kisses you again — slow, reverent, lips trembling against yours as his cock finally starts to soften inside you. you’re still stretched, still full of him, his cum dripping from between your cheeks. but you don’t want him to move. no, not yet.
jake’s arms wrap around you, his whole body shaking with adrenaline.
“i love you,” he whispers before he can stop himself. “i mean—i know that’s insane—but i—i literally love everything about you—i think i’ve loved you for a while—i just—fuck—fuck.”
you kiss his jaw gently, even as your body trembles beneath his. “we’ll talk. in a minute. just… stay. stay in me a little longer.”
jake nods softly, voice small and wrecked. “okay. yeah. i can do that.”
he buries his face in your neck, still breathing like he just ran a marathon, still inside you, still holding you like you’re the most fragile, precious thing he’s ever touched.
he doesn’t move for a while. just breathes — deep, shaky, warm against your skin. you’re trembling a little underneath him, your muscles twitching from the overstimulation, the stretch, the sheer intensity of it all. you can still feel him inside you — not just the heat of his body, but the fullness, the weight, the mess.
jake finally lifts his head just enough to see your face. his glasses are still crooked. his hair’s a complete wreck. and his expression is the most adorably panicked thing you’ve ever seen.
“oh my god,” he says in a hushed, horrified voice. “i broke you.”
you blink at him, dazed. “what?”
he sits up a little, still buried inside, and gestures at your whole body. “you’re shaking. like—full-body tremors. that’s not normal, right? did i damage your spine? are you having a seizure? oh god, did i hit something important?”
you start laughing — weak, breathless, but real.
“what?!” his voice is rising. “you’re literally crying two minutes ago and now you’re vibrating like a haunted vending machine—that’s not okay!”
you reach up and tug him down by the collar.
he blinks hard. “you’re… sure? because i swear to god, i’ll study anatomy until i pass out—i’ll get a certification, i’ll call a nurse hotline—”
you kiss his chin. “you just fucked me senseless. i think i’m allowed to tremble a little.”
he blushes all the way down his chest. “oh. right. that.”
then he looks down, suddenly remembering he’s still inside you, and his entire face combusts.
“oh my god i’m still in you.”
“yeah,” you murmur, lips curving. “kinda like it, actually.”
jake stares at you with wide, stunned eyes. “you’re teasing me. after what i just did to you?”
you grin. “especially after what you just did to me.”
he makes a strangled sound, then slowly — carefully — pulls out. you both groan, the sensation too much, too raw, and the moment he slips free, the mess starts dripping down your thighs and onto the sheets.
jake gapes. “oh. my. god.”
you raise an eyebrow. “wanna grab a towel, professor?”
“i think we need six towels. maybe even a mop. possibly a hazmat suit—”
he scrambles out of bed — pantsless, still a little dazed — and returns with a warm, wet cloth. he kneels between your legs and gently starts cleaning you up with a level of concentration usually reserved for defusing bombs.
“you’re being very… precise,” you tease.
“i’m documenting,” he mutters. “i mean—not in a weird way—just mentally. so i never forget how perfect your body is. ever.”
you snort. “you’re such a nerd.”
jake pauses. “but i’m your nerd, right?”
you look at him — jake is completely flushed, sweaty, wiping your inner thighs with shaking hands — and feel your chest squeeze.
“yeah,” you say softly. “you are.”
he exhales shakily, like that meant more to him than the sex. “okay. good. cool. i’m gonna pass out.”
you laugh as he finishes cleaning you, tosses the towel somewhere vaguely off the bed, and crawls back in beside you. you expect him to just collapse, but instead, he pulls you close, wraps both arms around your waist, and starts kissing every inch of your body within reach.
your collarbones. your chest. your jaw. even your shoulder blade, like he just wants his mouth on your skin, somewhere.
“i really love you,” he murmurs between kisses. “i know i said that too soon. and weirdly. and i literally begged to cum inside you while saying it, which is, like… not ideal timing. but i mean it. i’ve never wanted anyone the way i want you.”
you’re quiet for a second, fingertips tracing the curve of his back. finally, “i love you too.”
jake freezes. then pulls back to look you in the eyes, stunned.
you nod. “kinda been driving myself insane wanting you. watching you walk around in those stupid cardigans and jeans and glasses like you’re not the hottest loser i’ve ever seen.”
jake’s face goes red. he buries his head in your chest immediately. “shut up. you’re lying.”
you kiss the top of his head. “i’m not.”
he’s quiet for a second. then, muffled against your chest :
“so… does this mean we’re boyfriends now?”
jake looks up. eyes wide. lips pink and swollen.
“i’ve wanted to be since week one of living with you.”
you grin. “then yeah. we are.”
jake beams. “best. experiment. ever.”
you both dissolve into laughter, tangled in each other, exhausted and blissed out.
