Pairing: Virgin!Eddie Munson x fem!tutor!reader

Summary: Eddie’s failing class, so you decide to offer two different styles of biology tuition, textbook-based and *ahem* practical.

W/C: something around 4k (I didn’t do a word count after editing, sorry)

CW: 🔞 18+ MDNI!, NSFW, PWP, smut with a story. Exhibitionism (f), mutual masturbation (m+f), swearing, innuendo, pet names, slight sub/dom dynamic, subtle size kink? Both Reader & Eddie are overage. No y/n. Reader’s appearance is not described, it can be whatever you like.

A/N: A cute little bit of biology lesson-based smut. I’m a sucker for virgin!Eddie and wanted to see if I could write him. Let me know how I did! 😄

My masterlist

You’ve had a crush on the guy in your Biology class since the beginning of the year when you first saw him ranting on a table in the cafeteria. There’s something about him that’s so different from the guys you’d usually go for. You run in completely different social circles, you with the academically-gifted ‘Brainy Bunch’ (an eye-rollingly terrible moniker coined by the we-think-we’re-so-clever jocks), and him with his nerdy friends. Despite this you find him unusual and intriguing, not to mention hot as all hell. You guess the ‘freak metalhead’ look doesn’t work for everyone, but his long hair and rebellious dark ink are certainly doing it for you. You really want to discover what’s underneath those layers of denim, leather and torn shirts, your imagination only able to go so far as you ponder his form late at night in your bed.

However, girls talk, and you’ve never heard of him being with any of them, or even speaking to all that many. For all his bravado and apparent confidence, you’re reasonably certain that Eddie Munson is still a virgin.

And for some reason this draws you to him even more.

You’re pretty sure you’ve caught Eddie checking out your ass as it’s perched on a high stool while he sits behind you in the biology lab. On days when you’re in this class you’ve started to wear your tightest jeans, and your shortest skirts (though if anyone asked you’d insist it was a coincidence).

Somehow you’ve become inexplicably clumsy (but only in this class, how odd…), often dropping your pencil and having to bend over to pick it up, occasionally chewing on the end in contemplation when you know he’s watching, much to the chagrin of your teacher.

“Never put anything in your mouth in the lab, you should all know better by now.”

You smirk at the innuendo in Eddie’s direction and he quickly looks away, ears exposed by his lab-regulation tied-back hair a little pink at the tips.

You also often ‘forget’ or ‘lose’ equipment, asking him if he’s got a spare, or could he please get you a replacement from the cupboards, which he’s always more than willing to do (giving you ample opportunities to observe his denim-clad ass as he does so).

“Damn, I seem to be one test tube short. Eddie, would you be a doll and get me one from the cupboard?”, crossing your legs and subtly ensuring the hem of your skirt rides up just a little more.

Eddie looks you up and down (result!) and agrees.

“Thanks, you really are my knight in shiny, um, leather?” You wince slightly at your clumsy comment, but he takes it in his stride, continuing the bit by replying,

“Here you go, your majesty”, bowing theatrically and presenting the glassware to you atop his forearm, making you grin.

In another lesson: “Shit, I tore my filter. Eddie, do you have a spare?”

“Anything for the Princess of Biology.”

He gives you a little smirk, and you feel your cheeks heat slightly. You can’t help gazing at his strong, ring-clad hands as he hands you the little circle of absorbent paper.

It becomes somewhat of a game, you playing the Princess and he the rescuing knight.

But for all your teasing you genuinely do actually want to help him pass the class. You don’t want him to have to repeat the year - you’ve seen him play at The Hideout and you know he’s meant for greater things.

It’s just biology, it can’t be any harder than what little you’ve picked up about that complicated game he plays, which seems to be all numbers, convoluted plots and organising “campaigns”, whatever they are. You’re sure he could pass if he’d just apply himself.

Or, perhaps, he just needs the right tutor…?

You’d broached it with your science teacher, offering to help ‘any students who were behind’ for extra credits. After he’d agreed you’d approached Eddie that same day, offering to come to his home and help him with his overdue assignments.

He was confused and skeptical at first, thinking this could all be some elaborate prank, but you were gentle and persuasive, and he’d agreed to pick you up later that day.

You’re sitting on his worn-out sofa, draped with a well loved but soft blanket. You’ve spent the last hour trying to get Eddie to understand cellular respiration (“Isn’t it just, like, breathing in and out?” “No, Eddie, this is cell biochemistry, it’s a bit more complicated than that”), but nothing you attempt seems to be working.

He’s despondent, won’t look at you, and seems resigned to his fate of never passing this particular subject, interjecting with statements like,

“Look, it’s just not going in.”

“I don’t know how to make it stick.”

“I don’t think I’ll get it, Princess, even if you beat it into me.”

The innuendo (accidental or not) is driving you crazy. As is Eddie’s lack of self belief.

You’d even tried explaining it by using D&D analogies.

“Think of the chemical reactions like individual characters interacting in groups. Like, if this particular troupe disband and some make allegiances with another, the group has different skills and attributes now, right?” But after a promising start even that doesn’t seem to hold his attention.

In fact, the more animated you get and closer you sit, the more distracted and fidgety he becomes, unwilling to engage fully with you and shifting uncomfortably.

You move further towards him on the sofa, determined to give it one last shot, and force him to make eye contact with you.

Their colour and depth surprises you as you look into them properly for the first time, noticing their rich, swirling chocolate and whiskey hues.

Your eyes briefly drop to his lips, the soft pink, plump, velvety pillows looking mightily enticing. God, they’re perfect.

Goosebumps rise on your arm as you feel his surprisingly soft curls tickle your shoulder.

Okay, you knew he was cute, but up close? Fucking hell…

You lean across your notes and over to the text book that’s on his other side. Your thighs are touching, and as you twist the side of your breast makes contact with his arm. If he looked slightly down and towards you he’d be able to see right down the neck of your tank top. You kind of hope he does.

Huffing, you prod at the book with your hand, hoping that the diagram on the page might make everything clearer. The movement makes your boobs jiggle a little.

You hadn’t noticed he’d stopped breathing and he suddenly lets out a huff of breath, covering it with a badly faked cough. His cheeks have flushed a light shade of pink.

So, you definitely weren’t imagining all that stuff in class.

Fuck it. You consider this might be the only opportunity you might get to do this, so decide to grab it. After all, academic tutelage was only part of your motivation to get him alone, and something you’ve been thinking about for a long time, one of the fantasies that keeps you up at night, pops into your head. One that would definitely get his attention. And if you can’t help his confidence academically, perhaps you can help with it somewhere else. Call it interpersonal tutelage…?

With as much nonchalance as you can muster, you say, “Um, maybe we should take a break. Y’know, relax a little?”

You scootch away to the end of the sofa, putting your back against the armrest and bringing your feet up onto the cushion in front of you. You grab a couple of throw cushions and slot them behind you, getting comfortable.

Eddie seems to relax a little too once you’ve moved away, but still looks uneasy.

God, are you really going to do this? What if he screams and runs away, or worse, tells his friends, or your classmates..? No, you’ve been thinking about this for far too long. Oh, fuck it x 2…

Feigning a stretch, you arch your back and place your hands at the back of your waist, pushing your chest, and breasts, upwards. Then you move them to the sides of your ribs, glancing over the sides of your boobs, seemingly-innocently pushing them together. You move a hand underneath one of your breasts, cupping it gently in the crook of your thumb and forefinger.

Eddie is still sitting tensely on the front edge of the sofa cushions, stealing sideways glances at you through the curtain of his hair.

“C’mon, Eddie, get comfy with me. It’ll help, I promise.”

Self-consciously, Eddie shifts himself and sits facing you, cross-legged, at the other end of the sofa. You give him a soft smile, which he returns with a slightly bashful one of his own, afterwards rolling his lips inwards between his teeth.

Okay, it’s now or never. Are you gonna be able to concentrate on this, Eddie?

You hum quietly, and almost closing your eyes you run a palm down your chest and over your belly. You drop one knee slightly out to the side, and run your hand down the inside of your thigh and back up it, eventually pushing your fingers between your thighs and cupping your mound with your palm.

You see Eddie’s eyes widen and hear a stifled choke.

Your hand moves to fully cup your breast, and you lightly trace your thumb over your hardening nipple whilst the hand between your legs begins to apply gentle pressure, making you inhale deeply.

Eddie watches you, agape, bringing his hands together and clasping one hand over the other in front of him, you surmise to disguise his burgeoning bulge.

You open your eyes a little, keeping them soft and half lidded, and gently smile in Eddie’s direction, ensuring he’s still watching you.

Using both hands to pop the button and lower the zipper on your jeans, you tease yourself by running the pretty elastic trim of your your panties between your fingertips, pulling it slightly away from you and letting it snap back onto your abdomen.

“Uh…”, he swallows hard, and you internally groan at the sight of his Adam’s apple bobbing in that delicious neck, “What’re you doing..?”

“What does it look like I’m doing, Eddie? I’m… relaxing…”

Sighing out the last word, you choose this moment to slip your hand down the front of your underwear, sliding over your mound and dipping just the tip of one finger between your folds, feeling the wetness that’s already pooled there. Your forehead furrows a little and you let out a quiet, contented hum.

Eddie’s eyes widen further and his eyebrows disappear completely under his bangs, and he sounds a little like he’s suffocating.

He tries to move further away from you along the sofa, unsuccessfully however as he’s wedged against the other armrest.

“Uh, I can, y’know, leave, or you could use my room, or, I can take you home, or, or-”

He’s babbling, and looking everywhere but at you. That’s not what you want at all, and you’re also concerned that he looks so uncomfortable.

“I can stop, if you want…”

He rushes out a reply, almost shouting the first syllable.

“N-NO! Um, no, it’s okay, really.”

“Okay, Eddie, stay right there. Keep your eyes on me, I wanna give you a show.”

He looks even more shocked, jaw dropping open, and you think he might bolt. But after a moment it’s clear that despite being full of anxiety, fear and self-consciousness, his curiosity, hormones and horniness are winning out, and he fixes his gaze on you.

He manages to squeak out, “Ok-aay…”

You lift your hips, using both hands to push your jeans and underwear down your legs until they reach your ankles. You slowly splay your knees, finally exposing yourself fully to Eddie’s gaze. One hand comes back to your breast, and you pinch your fabric-covered nipple between your thumb and forefinger.

He takes in the sight before him, the soft fur around your core, your wet folds glistening in the dim light of his living room, your sultry gaze, the peaks of your hardened nipples now visible through the thin fabric of your top.

He lets out a stuttering breath as his hips involuntarily shift underneath him, trying to find some friction.

“Jeezus fuck, Princess, are you tryin’a kill me?”

You try to think of something that might help relax him.

“If it helps you can imagine that we’re still studying. How about a quick lesson in female anatomy..?”

You move your hand down and with featherlight touches trace your fingertips around your pussy.

“Now, this whole area is my vulva.”

Eddie gulps.

Making a vertical line you trace your fingers over your wet lips.

“These are my labia.”

Eddie’s lips press together and he lets out a stammering hum, closing his eyes momentarily before snapping them back open so he doesn’t miss a thing.

“Are you paying attention, Eddie? This part is really important. This-,” you inhale sharply as you trail your wet fingers upwards and make contact, “This is where you’ll find my clit- fuck-”

It feels so delicious you almost don’t manage to finish your sentence, and you let out a long, low hum. Part of you doesn’t want to stop, but you’ve got more planned. Moving your fingers down again, you say,

“And this, here? This is my vagina…”

With a smile, you watch him stare as you dip a fingertip into your sopping hole, letting out a low moan as you gradually slip it inside of you.

“You know what the g-spot is, Eddie? I can show you where to find it, if you want me to…?”

You slide your finger in further, curling it towards your front wall, almost managing to tickle that certain spot within and letting out a loud groan.

At the other end of the sofa Eddie gasps an inhale, whimpering slightly, and you see him press the heel of his hand into his crotch. The combination of his sounds and actions is making you impossibly wetter - the boys you’ve been with before didn’t do much of either, and you didn’t know how much it turned you on.

You watch his face as he stares intently at your weeping centre as you slowly, so slowly move your finger in and out a few times.

“D’you think you’ll remember that, Eddie?”

“I promise I’ll fuckin’ try, Jesus Christ…”

He swallows again, exhaling heavily.

Deciding it’s time for the main event, you bring the hand that was squeezing your breast down your body, moving your fingertips to your clit and applying gentle pressure.

“I want you to see how wet you make me, Eddie. I want you to know how much I enjoy you watching my ass in biology class, how often I’ve thought about it when I’m alone. How much I like checking yours out in those oh-so tight jean- oh!”

A particularly exquisite circle followed by a firm press on your clit makes you moan out loud. The combination of both your hands has you close, closer than you imagined you’d be at this stage. It takes much longer when you’re by yourself, and you’re surprised and excited by just how much you’re enjoying having Eddie watch you.

Eddie’s fully gripping himself through his jeans now and is breathing heavily through his nose. He looks big, and you salivate at the thought.

You really want to see what he’s been hiding inside that tight denim.

“Show me, Eddie, I wanna see you.”

Hesitantly, never having experienced anything even close to this before, Eddie mumbles,

“You, uh…?”

“I wanna see you. Take out your cock. Let me see all of you, please.”

He’s rubbing himself, and you can see how strained his jeans are, a wet stain now visible in the dark fabric.

Slowly, eyes never leaving your face and looking for any tiny indication that you’re uncomfortable or have changed your mind, he slowly undoes his button and pulls down his zipper.

His languid pace is killing you, but in a good way; you realise he most likely has no idea what this is doing to you.

He rearranges the front of his jeans, opening the fly wide and leaving nothing but a thin layer of checkered cotton covering his member. The tent it’s creating is impressive.

He watches you stare and run your wet tongue over your bottom lip.

Letting out a nervous breath between pursed lips, he pushes one hand beneath the waistband of his boxers, using his thumb and two fingers to hold his cock at the base. Using his other hand he slowly, agonisingly slowly, pulls the fabric out and downwards, gradually exposing his full member to the lights of the room and to you.

You pause your own movements and spend a moment taking it in. It’s long, with an impressive girth - you briefly wonder whether he knows what he’s packing - and it’s the prettiest shade of pink you’ve ever seen. Lengthy, veined, slightly curved, and thick, so thick.

Eddie watches your expression for a moment. Satisfied that you’re not freaked or about to run away screaming, he brings the rest of his fingers to join the others, wrapping himself fully in his fist and squeezing gently, causing a little bead of precum to collect on the tip.

You take in the sight before you for a few moments, then utter, completely honestly, “Eddie, in case no one’s ever told you this, you have a really beautiful dick.”

His face and neck turn the second-prettiest shade of pink you’ve ever seen.

“No one’s ever told me that before, Princess.” Adding, almost in a whisper, “In fact, no one’s ever seen it.”

He chuckles lightly through that last sentence, embarrassed at what he’s just admitted. The ego boost of your comments has clearly given him some confidence though, as he adds with a slight smirk, a little breathy as he runs the pad of his thumb unhurriedly over his tip, “You, uh, really think so?”

Oh, so he likes me watching him too?

You can’t take your eyes off of it.

“I really do, Eddie. It’s so pretty.”

As if to confirm your statement you resume your hand movements, adding another finger and resuming circling your clit with the other. You notice that Eddie’s started moving too, his hand moving over himself in a deft gripping and twisting motion, his hips bucking up every now and again.

For a few moments neither of you say anything, the only sounds in the room your combined panting breaths and the lewd movements of wet skin.

Your clit is swollen and supremely sensitive, and, pushing in a little further, your fingers just tickle that exquisite spot within you.

You moan as you imagine it’s Eddie’s pretty cock inside you. That he’s leaning over you, thrusting into you, hitting that spot effortlessly. Maybe even talking to you, telling you how good your pussy feels, how well you’re taking him…

Suddenly your eyes roll back in your head and your mouth hangs open, a gutteral moan emerging from your chest as you get closer and closer.

Bringing your attention back to him you mumble, hurriedly,

“Jeezus Eddie, I’m gonna cum, you wanna see me cum?”

“Fuck, sweetheart, I’ve never wanted anything more in my entire fucking life.”

Eddie’s words come out in a spluttering rush and on his last word your breathing halts, your muscles lock and you cum, hard, clenching around your fingers and letting out an involuntary strangled scream.

Somewhere in the back of your fuzzy mind you think you hear Eddie let out a loud, “Holy shhhiiiit!”

You come down a little, opening your eyes and locking them with Eddie’s. You ride out your aftershocks, humming as you feel your fingers inside of you and your juices running down them. You eventually remove your fingers from your cunt, leaving its puffy wetness fully on display, and trace them around your lips and clit.

“F-fuck, Princess, that’s the hottest goddamn thing I’ve ever fuckin’ seen…”

Eddie’s red-faced and panting, his cock still very much standing to attention in his now vice-like grip, the tip an angry red and leaking copious amounts of precum. His eyes are blown dark, the chocolate rims almost completely obscured. His face and neck are flushed and he’s covered in a sheen of sweat, and he’s clenching his jaw, looking like he’s trying desperately not to bust.

“Are you ok over there, Eddie?”

“Shit, yeah, yes, I mean, fuck.”

Breathily, you ask him,

“Do you wanna cum?”

“Fuck yes, I just, I didn’t know whether you wanted me to.”

“Oh I do Eddie, I really do. It’s your turn now. You gonna cum for me? Please, let me see you lose it, show me everything you’ve got.”

He breathes out a loud sigh in what seems like relief. You like how good he’s being for you, learning yet more about yourself that you didn’t know before.

His fist speeds up as his other hand comes to hold his balls, deftly stroking and rolling the flesh. His brow furrows deeply and his lips clamp shut around a low moan. He’s staring intently at you, eyes flicking between your face and your still-dripping cunt.

Suddenly his expression turns to one resembling surprise, as his eyebrows lift and his mouth opens, a string of expletives leaving those perfect, plump lips,

“Fuck, fuck, Jeezus, motherf-, oh my-, fuckfuckfuuuck!”

His jaw drops as his abdomen contracts, and his eyes fix on your cunt as he jets hot ropes of white cum into the air and over his fist and t-shirt. There’s so much, and it seems never ending.

The sight is even better than you’d imagined it might be and your hips buck up into your hand, making you press your fingers into your clit again triggering another aftershock, and you find yourself moaning along with him.

For a few moments there’s more silence, aside from your panting and heavy breathing.

Eventually Eddie chuckles a little, and you huff a breath out through your nose with a smile on your face.

You’re both a sweaty, sticky mess, but neither of you care.

“Fuck, Eddie, that was…” You’re lost for words.

“Amazing? Incredible?” Seeing the grin plastered across Eddie’s face is easily as gratifying as all the other stuff you’ve done tonight.

You both giggle as Eddie says, “Fuck me, Princess, you’re definitely the best tutor I’ve ever had.”

Neither of you really want to move, but some cleanup is definitely necessary. Eddie takes the blanket from the sofa and throws it in the washer, cleaning up quickly in the bathroom, letting you know when it’s free and returning in a change of clothes, throwing the others in with the blanket.

As you both process what’s just transpired you share timid glances and half smiles.

You both sit on the sofa again as you start to pack up your notes and books. In another unforeseen realisation, you’re surprised at how much you’ve enjoyed Eddie’s company, and the warm feeling you get inside every time he looks at you is entirely unexpected.

You realise you’re gonna have to be the one to say something, and give Eddie a smirk.

“So, how about next time we do some practical revision on, maybe, male anatomy?”

He looks a little surprised, but certainly not unhappy at the suggestion that there might actually be a ‘next time’.

“You really wanna, uh, tutor me again?”

Nodding in the affirmative, you reply, “Oh yeah, I think we’ve both learned a lot this afternoon.”

Holding his gaze, you suggest,

“Same time next week..?”
