First Time?

Request : Sooo..If we already had "Virgin! Sans x Seductive! Reader", then what about Underlust Sans x Virgin! Reader? (Would love reader to be really shy and oblivious, thank you ♡)

A/N : Gender neutral reader, AFAB anatomy & human reader. Kept the reader shy and oblivious but not 100% innocent, I had fun with this one. I love my boy Ace 💜 might be more sweet than some other oneshots due to the prompt but rest assured it's plenty filthy still Some kinks included : Praise kink (i'm a basic bitch for it leave me alone), minor degradation, lots of dirty talk, some overstimulaton, creampie, biting, brief talk of breeding and impregnation

"How far do you wanna go with this exactly?"

He breaks away from the kiss, purring seductively in your ear. His hands giving your hips a playful squeeze, you straddling him on his lap. Your face was completely flushed, you felt like you were gonna pass out from overheating. Thankfully your voice doesn't fail you as you squeak out a, "All the way."

Eyebrows (bone brows?) raise all the way, interest piqued even more than it already was. "And you're sure about that?"

"Y-Yeah I just uh-" you forced yourself to keep talking despite your flustered state, "C-Can you? I mean, do you...have...?"

A snort leaves him, "Hun, it's part of my profession, I have some junk in the trunk yeah. Buuut you be surprised how many clients want all bone to bone."

You would have laughed if you didn't want to mentally scream at yourself for wording the question so poorly, "I-I know that! I mean- ugh-" by pure impulse you shove your face into the fluff surrounding his vest, groaning into it as he just chuckles at you. But allows you a brief moment to compose yourself, "I know it was probably possible but like....I never got an explanation on like....what you have or how it works? For monsters I mean- I don't know what parts people normally have-"

The way you were trying to ask in aroundabout way if he had a cock or a pussy was adorable, your timidness regarding this was endearing but he can't stop the ever so slightly sinister smirk forming on his face as he goes to play with your hair. "It's all magic hun, it allows me to form a type of eco body. Really it can be whatever I want, I have can breasts, pussy, dick, tentacles, I could make my entire body covered in it but the jist of it is more magic, requires more energy. More elaborate the request, means more magic which means more energy."

It's all basic, a little bare bones if you will of an explanation but it got the point across.

However he proceeds to grind against you not long after that statement, something warm and hard pressing against your core that makes you gasp. "But by default we form whatever's more comfortable for us personally."

A cock in his case, but he's experimented with plenty of other things before.

You shudder at the feeling, warmth spreading through your core and you felt like you might melt. Body instinctively squirming against his own.

"....so you sure you wanna go all the way with this?"

Honestly you were a little nervous, but nerves or not too damn aroused to think about taking it back. You nod, "Y-Yeah, I trust you...I..." you bite your lip to suppress a little moan, your hips of their own accord trying to rub against his own but it did indeed get across what you were trying to say. I want you.

It renders him silent for a moment, it's not that he doesn't want to, far from it. However...he's fully aware that for him this is the hundredth time (stars above probably more than that he doesn't really keep count anymore) but for you it's your first time and the fact you wanna spend it with him- there's a fuzzy feeling somewhere in his rib cage.

"Alright then,"

Just like that, you found yourself flipped around and pressed against the cushion of the mattress. Sans placing himself in-between your legs, you further feel his erection press against you as it seems to further stir to attention. You barely stifle a groan and Sans doesn't even try to hide the lewd sound that comes out of his mouth.

You were always so easy to fluster, the way your face would just light up anytime he did the bare minimum of flirting and how you just melted into his touch, it invokes a more dominant side of him. And with you underneath him like this, suddenly he feels like a wolf that's been starving for ages and you're a full course meal just laid out for him.

As tempting as it is to start right away, he's taking his time. He'll enjoy himself no matter what, but the same can't be said for you. This is uncharted water and there's no need to rock the boat too much, but you'll be getting wet either way.

"You're tense, relax," his hands give your hips another firm squeeze before his hands trail up to grope your chest, "Nothing you don't want is going to happen,"

You hated how easily you squirmed underneath his touch, how sensitive you were, it was embarrassing even if Sans found each and every little reaction utterly adorable. "I-I'm not worried about you doing anything, I- I- don't wanna do anything wrong, I-"

"Well, don't worry, you don't gotta do anything you don't want.....you'll make a cute little pillow princess," he purrs, hands still wandering and squeezing whatever he could find. "You're gonna be such a cute little cocksleeve,"

His voice shifts to more of a purr, his cock twitching at your reaction but he reels himself in enough to notice it's not one hundred percent a positive reaction, "Too far?"

"Ah...a little? No? I mean-" it aroused you way more than you thought it would, dirty thoughts flood your mind as you can't tell if you want him to keep talking like that or try something else. "Dial it back a bit? Just like by one I mean.....I-I kinda liked it?"

He hums, honestly there is a sense of fun to this, getting to figure out what's a no and a yes. His own little puzzle to solve, his brother would probably be proud. "Got it, okay with me getting these clothes of ya? Don't worry I'll be careful, you always looked good with this shirt."

You didn't trust your voice but you nodded and you tremble as you feel those boney digits run over your skin, working wonders as your shirt is removed. You closing your eyes as your chest was now completely bare to him, your face was impossibly hot like you were sick with a severe fever but in a good way? You didn't want it to stop but it was overwhelming nonetheless.

"Relax honey, I got you." he hummed, hands going down to your pants. "Just listen to me....alright?"

Seems like he wanted some response given how he stopped his hands from undressing you further, you nod. "O-Okay.."

"See, normally I'd set up the safe word and all that jazz, but let's figure out what your limits are before we test them. So, literally all you have to say is no and I'll stop, and you can stop it for any reason, especially if it hurts. Let all your reactions come naturally, listen to your body, got it, hun?"

The tender care he treats you mixed the warmth you feel in your crouch and the heat radiating from his pelvis makes for an intoxicating feeling, "G-Got it,"

"Good, now...." Your pants start to come undone, you don't realize how hot it was down there until the chill air hits your pussy. Pants pealed off, his digits unhooking around your underwear. "Answer a few questions for me..." it's painfully clear how wet you are, especially as the final garment is removed.

"Have you ever touched yourself?"

You swallowed dryly, a wave of embarrassment hitting you as you speak up. "Y-Yeah."

"Speak up hun,"

"Yeah." you said more clearly, trying to look at the ceiling or anything but Sans right now but it's easier said than done.

"How so? Tell me what you to yourself."

"Um...sometimes....I try and finger myself...I don't get good enough friction, I really just rub my clit...." you felt like you might actually die right now, your mental HP taking several hits.

"Like.....this?" A finger is dipped between your folds, caressing them gently and the moan you made further added to your internal shame.

"Y-Yeah." he keeps doing that, slow rolls over your clit that make you nearly see stars. It shouldn't surprise you how good he is at this, but each spark of pleasure makes you jolt. A lower whimper escaping from you.

"I got cha' baby I got cha' remember you can back out whenever you need to." he keeps his tone calm and collected but God damn does having you like this made him impossibly hard. His free hand undoes his impossibly tight pants, wrangling his cock free so he can get some relief as well. Hand wrapping around the vibrant purple shaft, starting to stroke himself.

Your eyes widen a bit as you catch glimpses of his cock but can only rasp out another moan as he pinches your nub.

"What do you think about when you touch yourself?" he asks, tongue rolling out of his mouth, twisting sinisterly. "Anyone? Anything?"

"I-I think about...you..." your huffed out, another low sound following it as he spreads your legs to further expose you.

"Me? Doing what? This?" he asks, fingers now trailing down deeper to circle around your entrance. Applying the bare minimum of pressure as he's truly trying to figure how tight you'll be. "Or something else?"

"T-This....touching me.....f-filling me up with your-" A singer finger is pushed in, you gasp loudly. Them being trailed in and out to tenderly massage your inner walls.

"With what? Tell me baby,"

"Y-Your cock-" you moan lewdly, his finger curling to make your cunt clench around him. "To be f-fucked by you."

"Yeah? You want this?" you look down to see him other hand stroking away at his magical formed member. You can't help but marvel at it, the shape and color was vaguely what you expected but the glow It gave off was a surprise. Then there was just how veiny it was. Your insides clench down tighter around his finger, something you know he noticed from his giggle.

"Yeah..." you admit dumbly, it was true after all. Especially with all the work he put into riling you up. "P-Please...?"

God, he can feel the small amount of precum released from his shaft at those words. Another strong wave of magic ripples through him, compelling him to force the length of his cock to something bigger. Absolutely fill you and wreck you, break that tight hot cunt, but it's a thought stored away for another day.

For as turned on as he was right now, you were coming (ha) first. Sans reminded himself of his own words, let's see what the limits are before we try to test said limits. Which is why he keeps his length at large but manageable. He can change it if need be.

"All you had to do was ask sweetie, you're always so good to me after all." another purr, hands on your hips as he starts to line himself up to your entrance. "This can hurt a bit hun, but it shouldn't hurt a lot. Just relax, tell me if it's too much." you feel the head of his cock brush against you. First he flips it through your wet folds, a moan leaving as it brushes against your clit.

He huffs, eyes going a bit hazy as he coats yourself with your arousal before positioning himself again. The way he smiled at you was so sweet yet so devious.

"Ready?

"R-Ready!"

You didn't know if you could wait anymore, which thankfully you didn't. He started to push his hips forward, entering inside you bit by bit. You moan loudly, filling him sink deeper into you. Claiming your tight virgin hole. He groans himself, eyes glowing as drool starts to trickle down his chin.

"Oh fuck," he rasps out, "Good lord hun, tryin' to milk me dry already? You really did want my cock huh? You feel so fuckin' good, oh, so fuckin' good. Feel how perfectly you wrap around me, you dirty fuckin' thing."

Walls clench down impossibly tighter at those words, drinking in every ounce of what he has to give you completely. You moan his name out loudly, a kiss his placed on your neck and you close your eyes again for a bit.

"Good, good, good, so fuckin' good. You almost got me all in ya, sweetheart. Ooooh, this pretty pussy is so tight and you're doing so good," he coos repeatedly, adding to your arousal basically baptizing his shaft at this rate. The pressure you feel as he sinks deeper into you is something else, the magic that sparks from his member is likewise further urges you on. The gasp you make when he's completely hilted inside you was painfully lewd.

This was nothing compared to your various fantasies, all those nights with your flushed face buried into a pillow as you touched yourself imagining how he'd take you and nothing even compared. He stopped, something you were more than grateful for you already feel yourself about to cum and while it would stroke his ego (and more) you felt the shame in just how easy it was.

"Okay, hun?"

You force himself to answer the question, your hips subconsciously grinding against the phallic shape inside you. "Y-Yeah, I- fuck-"

"You close?" his tone is genuine but the natural smugness is there.

"Yeah....s-sorry-"

"Ah-ah," he chastises playfully, "Nothing to apologize for hun, let it happen.....look at me,"

Eyes open, how long had you had them closed? You weren't sure, it was getting hard to keep track when they shut and when they opened, but right now your eyes solely focus on his own. Once you do, he starts to move and you moan loudly. One of his hands caress your cheek, cupping your face as if to prevent you from looking away while the other is back on your hip. His smile is sinful as always but there's something soft in his expression, outright loving about it.

"We're gonna experience this together, let yourself go. Let me feel you cum," he mutters, keeping his thrusts at a steady pace and you feel yourself getting closer and closer to the edge. The thing that finally does it when he kisses you, it started out tender but his tongue quickly dives into your mouth. And your orgasm hits you like a freight train.

You would have screamed if your mouth wasn't muffled by his own. He pulls away from it, hips still thrusting through your orgasm and his voice rasps out a loud "FUCK!"

A bit of self control is lost here, his pace increases and it absolutely overwhelms your senses. A squirmy wriggling mess underneath him as he keeps drilling into you, filthy praises leaving his mouth. "Good, fuck, so good for me! God fucking damn babe, so good, so perfecttt-"

It he keeps this up your might just cum again, your senses getting kicked into overdrive. Eyes rolling to the back of your head followed back a loud yelp as the head of his rock positions right against your sweet spot, which of course he notced.

"You good? We can stop whenever you want we can-" a groan leaves him, raising your hips up higher allowing him to hit your g-spot with each thrust and you feel like you're seeing stars. You almost consider telling him to stop or slow down a bit but you really don't want him to. You simply cry his name out in ecstasy.

"Oh baby," he purrs, nearly growls. Going to place a kiss to your neck, but it turns into a full blown nibble. He would have apologized but the moan you make indicates that he should keep doing it and he does, neck and shoulders being painted with hickies and his smeared lipstick. His tongue even trailed over a few of them.

He's nearly as far gone as you are, his thrusts are all instinct and they get rougher and rougher. Which you don't even mind, fully ready to accept the fact that you probably won't even be able to walk tomorrow probably won't be able to for the next week. Another whimper leaves you as an orgasm starts to build again, but this time you certainly aren't alone.

"G-Gonna let me cum inside you pretty baby? Can't get ya pregnant- not yet anyway, hggnh!" he's fighting to regain control of himself but your insides are wrapped around him so perfectly. Almost as if inviting him to keep going, to absolutely fill you over again and again.

And you do.

"Y-Yes! Yes please, Sans, please-" you honestly don't even care if he does actually knock you up despite his reassurance otherwise. You want him and you're so fucking close-

There's something akin to a growl leaving him again, deciding to throw his full strength into his last couple of thrusts and it sends you screaming as you clench down on his cock again. He groans loudly, fully sheathing himself inside you as he unloads, the magic from his cock glowing violently to the point you can make out the outline of it inside you. Especially as he pumps his seed deep within you.

Everything goes silent for a bit, the two of you both panting heavily with the smell of sex fresh in the air. After a bit he teasingly thrusts his cock forward again making you squeal, "Sans!" you know he's not actually attempting another round just getting a kick outta playing with your overstimulated cunt. The bastard chuckling all the while.

"Gonna pull out, you alright hun? Might have gotten a little carried away toward the end there," a hint of remorse as he sees the state you were in, inching his cock carefully out of you.

"I'm fine...that was....that was incredible, you're in incredible I..." you have trouble regaining those words, trembling as he pulls out and you feel his cum trickle out of you. "Did...I...?"

"Do I gotta keep saying it? You were perfect sweetheart," he teasingly pokes your forehead, before sitting up properly to pull you into his arms. "How about a bath, eh?"

Your face is still stupidly flushed and you nuzzle into the crook of his neck as he picks you up. "You'll be joining me....right?"

He chuckles, but he can't hide the fondness in his tone. "Sure, I made ya a messy, I can help clean ya up."
