Casper NSFW Headcanons

Casper NSFW Headcanons

I am not immune to the grim reaper babygirl even a little bit. These are more "first time" headcanons.

Mentions of male and female anatomy for MC/reader/you, dom reader, oral (giving and receiving), a lot of teasing/praising, and inexperienced Casper, topping and bottoming. Also, this gets fucking LONG. REALLY LONG. Honestly should've just written actual smut but the voices told me to write headcanons...

NSFW CONTENT BELOW CUT, 18+ MINORS DNI, RESPECT THE HONOUR SYSTEM

Since Casper has never fallen for a mortal before and is/was a workaholic, he’s inexperienced in all matters of intimacy, especially physical.

Like, if you’re not his first kiss then you haven’t kissed him yet levels of inexperienced.

The first thing you two do, after you’ve pushed him down on your bed with glee, is kiss. And it’s okay! He has really soft lips, and it’s a simple peck, so not a lot to mess up there.

It’s when you try to do deeper, longer kisses that his inexperience shows.

Should he be tilting his head more? Should he push more against you- oh god there’s your tongue, in his mouth, feeling around, does he do the same? Where does he put his hands? 

You have to really walk him through it and be patient about it. His tongue work is going to be awkward and sloppy, and you’re gonna bump teeth the first couple times, but he’ll eventually get the hang of it. 

You’ll also have to remind him that he’s allowed to pull away so he can breathe. His face is cute when red, but you don’t wanna see if it’s just as cute when it’s blue. (I mean, it’s not like it’ll kill him, but still...)

You’d be lying if you said you didn’t think his flushed face, wet lips, and panting were cute though. 

Hickies are fun. It’s super easy to leave teeth marks and suck bruises on his pale skin, and it’ll make him whimper as you do. Tease him about how flustered he is over a couple love bites, and he’ll get pouty and deny it. 

In fact, he’ll wanna mark you up as revenge, but he also just only learned how to kiss like ten minutes ago so he’s gotta learn how to give hickies too. He gets frustrated when he sucks on your skin but not enough to leave a lasting mark. That said, it is fun to do, and your skin is so soft against his tongue and lips, so he’ll keep trying. 

He sits back all smug over finally leaving a bruise, but his neck is covered in teeth marks and bruises. Please, please bully him about that. 

I need to stress this right now: you can tease and bully him as much as you want, do not degrade him.

The harshest name you can call him is a slut, but it has to be wrapped in praise (i.e. “such a good little slut…”). You could probably get away with calling him pathetic in the heat of the moment every now and again, but that is it. He will not react well to degradation. He wants and needs to be praised.

Play with his hair. Pull on it so you can tilt his head back and leave kisses all over his neck and jaw. Kiss up to his ear to tell him what a good boy he’s being, your sweet little reaper. He’ll melt right then and there. 

Constantly feeling you up, it’s both his attempt at teasing you (especially with his cold hands) but mostly just him trying to figure out what he’s doing. If you tell him he’s not allowed to touch you, then he’s gonna be white knuckling the sheets. 

Another easy way to get some really pretty noises out of him? Play with his chest and nipples, they’re very sensitive. 

He’s ashamed at how easy it is to get him hard. You don’t have to do that much. Just straddle him and make out with him for a bit, let him touch your body or play with his hair. You’ll feel him press against you in no time, and he’ll whine at the friction of his pants against his cock.

Just whatever you do, don’t touch it. Don’t feel it, don’t rub it, and absolutely do not grind against it. Not unless you want him to cream his pants immediately. (Let's be honest: you do.)

Actually, you won’t even need to touch him to make him cum. All your teasing, your kissing, touching, the warmth of your skin and smell of your shampoo and your hands running through his hair and the sound of your voice, it’s too much.

You’ll feel his hips jerk and back arch, and he’ll make the prettiest little noise you’ve ever heard. It’ll take you a moment to realize what’s happened, your eyes trailing down to see the wet spot where his cock is pressed up against his pants. 

When you do finally let his cock out, it’s rock hard, dripping precum, flushed a pretty shade of pink and has a patch of white hair at the base. He keeps it well maintained, which you shouldn’t be surprised by considering his thorough skincare routine. 

Any and all bravado is out the window the exact moment you touch his cock. Whatever insult or snarky comment he had on his mind or smug look on his face is immediately gone once he feels your fingers graze it. 

You can tease him as much as you want when he’s like this and he won’t do anything about it. Can’t do anything about it. He’ll be a whiny mess for you whether he wants to be or not, but in the moment, he doesn’t care as long as you touch him. 

It won’t take much to make him cum, just pump your hand up and down while you kiss and bite at his neck, and tell him about how cute he is right now, how good he is, how he can just relax because you’re gonna take such good care of him. 

The only reason he doesn’t immediately cum is because he’s masturbated to the thought of you before so he knows what it feels like, but his “self care” is nothing compared to you yourself actually touching him. 

He will immediately cum if you go down on him. With your hand it was one thing, but your mouth is so warm and wet and your tongue feels so good he can’t hold back. 

His hips will buck up reflexively, shoving himself deeper inside by accident as his cum shoots down your throat. He’ll babble apologies profusely for it but is immediately cut off by his own sobs when you keep going.

God it would be so fun to overstimulate him. He’d be crying, tears in his eyes, babbling about how it’s too much, it feels too good, and his body’s shivering and writhing because it doesn’t know if it wants to get away or if it wants more. 

Edging would also be fun, just to hear him whine and beg for you every time you brought him to the edge, only to slow down and pull back. He’s pleading with you to let him cum, please let him cum, he’ll be good, please. How can you say no to that face?

Since you’ve treated him so nicely, it’s only fair he returns the favour and goes down on you too, right? Right. 

You’ll have to talk him through it, how you like to be touched. Go ahead and grab his hair, use it to really guide him by pulling his face closer to your sex. If he’s not all mushy by that point, he’ll tease you about being needy for him (like he’s one to talk…).

Sucking cock is simple enough, though you can see in his eyes he’s a little nervous about it. He’ll slowly pump his hand up and down as a tester, gauging if you like what he’s doing and if he should go faster. He’ll then stick his tongue out and hesitantly lick the tip, and that surprised look on his face when you moan is to die for.

It’s enough of a push that he’ll take the tip in his mouth and lightly suck on it while stroking you, and every time you groan about how fucking good his mouth feels, it encourages him to take more of you in his mouth.

Be vocal with him, but most of all, be patient. Tell him what he’s doing right and what you want him to do, guide him by his hair if you wanna, but don’t expect him to be ready to deepthroat you yet. He’s still gotta work on that, so just savour the feelings he’s giving you now.

Let him know when you’re going to come, and more importantly, where, because otherwise he won’t know what to do. If you don’t wanna cum in his mouth, he’ll pull himself away and keep jerking you off until you cum. Try not to cum on his face, as tantalizing as the sight is. You can maybe get away with it once on purpose, or if it’s an accident.

Casper’s not a spitter, but he’s not a swallower? He actually doesn’t know what to do when you cum in his mouth. He’ll literally sit there with his mouth full and dick hard just staring at you until you either tell him to swallow or give him something to spit in. Call him a good boy when he swallows. Or if he doesn’t. Just call him a good boy either way.

It takes him some time to figure out how to eat you out right, but luckily for him it still feels really nice when he’s practicing. 

His fingering technique needs a little work, mostly because he’s very unsure of himself. One’s not enough, two looks and certainly sounds good on your end, does he need to add more, or will that hurt? He wants to make sure he’ll fit when he gets to the big finish, but three fingers feels excessive, unless you like that? Is he going too fast, too slow, too deep, not deep enough? Does he curl his fingers here? Oh, you squeezed his fingers just now, that means he’s doing something good, but what’s he doing?

Thank god for the clitoris. Finds it without you having to guide him because it’s literally at the top, it’d be harder not to find it. All you need to tell him is your preferred pace and he’ll rub at it with ease, taking immense pride at how quickly you fall apart with that dumb little smile. (Just ignore him grinding against the bedsheets or stroking his cock, he’s totally in control right now.)

Kinda like with giving head, he starts with little kitten licks to your clit before getting more confident as he listens to your moans and praises. He’ll especially love it if you push his face into you so he can suck and lick harder. He’ll groan against you unintentionally, but when he hears the sound you make at the vibrations of his mouth, he’ll latch onto your clit and start humming and sucking as hard as he can.

Loves the feeling of you cumming on his tongue. The way your hips buck up, the way you tighten your grip on his hair, grinding against his face, your juices slathered all over his lips and tongue, gods he’ll never get over it. He’ll clean you up with his tongue and sit up, trying to look smug, but he’s not fooling anyone with the flushed face, the hearts in his eyes, or the wet patch on the front of his pants.

He’ll think you’re weird if you wanna kiss him after he goes down on you, but quickly shuts up once you plant your lips on his. Your tongue in his mouth is a very compelling argument.

Now comes the part he’s been most excited and nervous for; actually being inside you.

You are taking the lead regardless, because he doesn’t know what to do. Well, he knows, but he’s not fully confident in his abilities.

Just lay him back, tell him all he has to do is relax. You’ll take such good care of him.

He is tense when he feels you straddling him, your bare sex rubbing up against his teasingly. He wants to tell you to get on with it already, but his mind is in a daze and the only thing he can focus on is telling himself not to cum yet, you haven’t even put it in.

He’s gripping your bed sheets or your hips as tight as he can when he feels you finally start to sink down on his cock. He can cover his mouth, grit his teeth, whatever, but you KNOW that boy is whimpering inch by inch.

It’s enough that once you actually make it to the base, he’s reduced to the most pitiful mess of a grim reaper, trying so hard to keep what little composure he has, and the two of you have hardly started?

He will not last long in this state. The feel of your tight warm walls hugging around him so tight, and the way you move up and down his length is too much for him to handle.

He’s sorta sensitive about how quickly he cums, so you have to be careful about how, when, and if you tease him about it. You can tease him when he creams his pants, so long as it’s along the lines of “you feel that good already?” 

When he cums prematurely inside you, be gentle with him, coo in his ear that it’s okay, it happens sometimes, you’re happy you make him feel so good, he’s being such a good boy for you.

And then you milk that poor boy for everything he’s worth. Watch his teary eyes roll back as his hips buck up to meet yours, shooting load after load until you’ve drained him of everything he’s got. He’ll be incoherent, sobbing and muttering “please please please” because it’s the only thing he’s able to say.

Hold his hand.

As if this google doc I’m writing in isn’t long enough, let’s talk pegging.

He’s going to be nervous about bottoming, he won’t even pretend he’s not. He doesn’t really know what he’s getting into, but he’s willing to try so long as you talk him through what you need to do.

In theory it’s all good, until he has your fingers thrusting into his hole, pressing into his sweet spot while you purr in his ear about all the things you’re going to do to him tonight. He really should have seen that coming considering it’s his Sunshine we’re talking about here, but he’s in too much pleasure to complain.

He’ll be too embarrassed to be face to face with you, so you suggest doing it from behind. Again, great in theory, until you have him face down ass up with your chest to his back. This position is arguably more embarrassing, but Casper is also stubborn and at least you can’t see his face.

Kiss all over his neck and shoulder blades and along his spine, it’ll make him shiver.

You have to take it really slow at first, of course. It’s his first time doing something like this, and you don’t wanna hurt him. Once you’ve slowly inched yourself to the base, give him a minute to get used to the fullness.

You’ll start slow and soft, but you don’t have to stay that way. In fact, he’ll love it if you start going faster, harder, deeper. He wants to feel you hit his prostate again and again, making him see stars every time you do.

You don’t even need to touch his cock, he’ll be falling apart anyways with the way you fuck him, but it’s so fun to overstimulate him anyways so go ahead, jerk him off while you do it.

He’ll try to muffle his sounds in the pillows. Sure, you can let him because it’s honestly really cute, but you can also pull him away by either tugging his hair or grabbing him by the jaw and lifting his head up. He’ll be a drooling, teary eyed mess, but he’s your teary eyed mess. Make sure you tell him that.

If you can, don’t be shy filling him up either. When he’s all fucked out, the feeling is absolutely addicting. Will probably get grumpy about the mess once he’s in a clearer headspace, but he’s also not gonna tell you to stop.

Oh, he’ll be nothing but mush when you two are done the deed. Not only is he too tired and blissed out to move, but he’ll be so cuddly and sweet, murmuring about how much he loves you and how good you are to him, for him. (He will vehemently deny he was that sappy once he’s snapped out of it though.)

Cuddles are absolutely mandatory post sex, he needs a little skin on skin time and to relish in the afterglow before the two of you get cleaned up.

It’s as you two are huddled together under the covers, about to fall asleep, that you hear Casper groggily mumble a little “thank you,” for treating him so well for his first time and showing him the ropes.

He’ll smirk at you and say that next time he’s going to use his knowledge against you, but both of you know that it doesn’t matter how experienced he is, it’s not gonna happen. 

You don’t get the chance to poke fun at him about it though, as he’s already fallen asleep. You kiss his forehead and cuddle up closer.
