Day 3 of Kinktober 2022

Summary: you get the bright idea to bring up double penetration to your two boyfriend's you don't regret it.

Props to my beta reader for today - @sasualblxd - thank you again bae <3

1,175 words.

The three of you are inseparable. Some would think you're connected at the hip. Even when Katsuki's going through it he's still got time and space for the two of you. And Kirishima would never turn down the chance to hang out no matter how he feels.

The rare, but passionate, and soft dynamic between the three of you is exactly what you needed, in all honesty. The vast difference in personalities balance eachother out, and the three of you are thick as thieves, like you're tuned into your own little frequency.

Most days are spent with the three of you sitting in your room, doing apprentice work or playing Mario kart, during which Katsuki would beat your ass and then proceed to lazer Eijirou without remorse. However, sometimes the air gets a little hot and heavy.

Katsuki straddles you with an expression of shock, his eyes big and wide as he lets his usual tough exterior drop.

"Are you-... Are you sure-?"

It's at this point that you want to hide away and pretend you never said anything, but Katsuki pries your hands away from your face as Eijirou tilts his head like a confused puppy. He turns his body in your direction and the mattress dips a little at the extra pressure, and you squeak as your face heats up even more.

"Yeah- I wanna... Try it."

You can tell that Eijirou is about a second away from fussing over you and telling you how shouldn't feel like you need to do this for them, but he's wrong. You want them both inside of you.

In the past you had stuck to cuckolding and voyeurism, and at the very most they would spit roast you, but they had never double stuffed you.

You can't help but drool at the thought. Katsuki sputters a little and it's one of your absolute favourite sights when he gets all flustered like this, his eyebrows furrowed just barely and his cheeks all red. His blush even dusts his collarbones.

The air is tense with a pregnant pause before Eijirou snaps. The idea just seems too good, and if you've said you wanted it, he'll stop at nothing to give it to you. And that's all it takes for Katsuki to warm up to the idea as well. Your two eager partners loom over you greedily, and their chuckles synchronise in a throaty chorus that has your thighs rubbing together and your underwear soaked.

"Huh... So you wanna take us both, yeah? Awful cocky of you to think you can handle that~"

Anticipation pools in your underwear until they're pulled to the side, peeling away from your pussy lips to make room for Katsuki's fingers under your skirt, already scissoring you open.

"Geez, so wet. We haven't even touched you yet."

Katsuki's voice is like dripping gold, rich and sultry as he eats up the sight of your drenched skin beneath him, and the second he flicks piercing red eyes to look up at your face, monitoring your reactions, you're a blubbering mess, your words escaping you amidst breathy moans.

"Hey now, don't forget about me, babe."

You can't even compose yourself enough to think of a response to his teasing, but you don't need to as he leans down to press a delicate kiss to your lips spiderman-style, his rough lips colliding with yours after a few more seconds.

The air in the room turns hot and already starts to smell like sex as you get lost in the haze of pleasure and lust, and your hands make their way to languidly play with Eijirou's loose hair, which falls down over your face and just barely reaches his shoulders.

Katsuki takes the liberty of pressing his tip against your cunt first, rubbing his pre against your clit and fucking around for a few seconds, but you're not necessarily mad. You're not even sure when he took his pants off but you're just glad they didn't settle who goes first by playing rock paper scissors again. Nothing could've ever prepared you for that, but after being given a tennis-ball sized lump on their heads, they've never repeated the offense.

Katsuki's cock twitches happily as he groans, not even bothering to lower his volume a little, and you wriggle at the stretch. It's really not too painful, given that he's quite girthy, and the sounds he makes are the real cherry on top.

Immense self-restraint is something the blonde prides himself on having, but even he can't resist a few weak thrusts before he starts to stretch you out with his fingers again. A deep breath is sucked into your greedy lungs as you finally part with Eijirou and he flashes you a toothy grin as you recover, before manoeuvring down to your hips and replacing Katsuki's fingers with his own.

Your shark-toothed boyfriend takes a little longer to prep you than Katsuki does on average, and especially now that he's about to try something so potentially painful, but you suffer in silence as your pussy clenches and your juices leak onto the sheets, and you practically cry in relief when he deems you stretched enough.

The room spins and it feels like your organs struggled to keep up with you as you're yanked up by a sweaty, impatient blonde, and God, you didn't even realise that Katsuki must have serious blueballs right now.

Kirishima's warm, hard as rock chest is firm against your back and your legs tremble with anticipation as you finally get what you've been begging for, and more stuttered gasps melt with your boyfriends' when you finally feel his cock pressing deep inside of you and rendering you breathless. Your cunt is stretched out perfectly over your partners, and it take everything in you not to cry as your eyes roll back.

They've never felt this kind of pleasure before. Each rub of their cocks against eachother sends pleasure straight to their brain as little hearts appear in their eyes while they leave sloppy, lustful kisses on your neck and shoulders. What's really fucking hot is how they tilt their heads to kiss eachother over your shoulder as you catch your breath again, exchanging tongues while your pussy throbs.

Their hips move in steady rhythm, your G-Spot never knowing peace while they pound you, groaning and panting as hot breath hits your neck, and if it weren't for the boys holding you up you would be a little puddle of goo right now.

Katsuki cums first, filling you up and pumping you full with his sperm, and it only brings Eijirou closer and closer as he fucks into your wet heat, the blonde's seed running over his head and leaking down his balls. He delivers one last punishing thrust as he reaches his orgasm, fucking it into you to ride it out before slowing to a stop, chest heaving with exertion.

The sheets are ruined and your thighs are covered in sweat and sperm and your own mess mixed together, making your thighs glisten and stick together slightly.

Day 11 of Kinktober 2022

Summary: Eijirou loves you so much, he just can’t help but fuck you stupid.

Props to my beta reader for today @lovinglyselfish - thank you for your amazing help! Drop 'em a follow! :)

515 words.

The majority of your night is spent pressed underneath your himbo boyfriend, Eijirou Kirishima, covered in sweat and out of breath. His hot, rock solid chest is pressed flush against your back as he fucks you raw, sharp teeth nipping and kissing at your neck and ear.

It’s like he’s in a daze, mumbling precious little “I love you”s and leaving evidence of his touch all over your neck and shoulders in the form of bite marks and dark hickeys that are sure to kick up quite the fuss in the morning. He fucks into you at a pace that has you aching all over, the rough slide of his dick against your pussy walls making even more of your slick drip down onto the sheets and run down his legs. He pants loudly and each quiet whimper that you hear from behind you has you squirming and clenching around him.

You’re so happy that he feels good, and that he wants nothing more than to be buried deep inside of you late in the night until the sun peeks through the slight gap in your curtains. It’s his favourite stress relief, to fuck you stupid like this.

Well defined hipbones, seemingly carved out of marble slam into your plush ass as he pistons his hips at a bruising pace. It’s been hours. Sweat drips down your brow and off the cupids bow of your lips, down to soak into the pillow, and you feel little droplets of what you assume is either sweat or your own juices running down the back of your thighs and pooling in the little dip at the back of your knees.

Exhaustion pulls at your heavy eyelids as your body is rocked forward with each powerful thrust, and you can’t think. Eijirou must’ve dumped his load inside of you without pause at least four times by now, but you lost count after the third hour. by your guess, you’ve been manoeuvred around the room and fucked on every possible surface for the last four and a half hours, and by now all you can do is moan like a pornstar and cry on your lovers cock.

You can feel him in your belly and you don’t even have the sense to be thankful that you’re on birth control. You want him to breed you full and keep you stuffed with his cum for the rest of your life. The only thing on your mind is him, and how good he makes you feel when he slams forward, pushing you into the bed and filling you up as yet another orgasm has you sobbing and biting your pillow, clenching around him and shaking almost violently. Your cunt spasms around Eijirou’s, now spent, cock and every movement from his end has you tightening so hard it’s almost painful. 

Oversensitivity has you closing your thighs and trembling, mass amounts of cum and slick leaking from around his quickly softening dick, nestled comfortably inside of you, and you can’t even think to be happy that now you can get some much needed rest.

Day 16 of Kinktober 2022

Summary: he's always been obsessed with your tits.

Props to my beta reader for today @sasualblxd - thank you for your amazing help!

556 words.

Kirishima Eijirou was a "tits over ass any day" kind of man. It seemed as if every ten seconds had him reaching up your shirt to manhandle one of his stressballs.

"They're just so... Squishy... -a-and soft-"

That's exactly what your boyfriend said when you asked why he was so enamoured with them. Once deep, scarlet hues are now reduced to a thin ring around wide pupils, and past swollen lips lie sharp teeth that you find yourself wanting embedded into your breasts.

You love his obsession with your breasts. You're proud of your body, the self love that you'd been teaching yourself rearing it's head and finding a way to the light. Although, Eijirou, the sweetheart that he is, just loves your breasts because they're yours.

He lays behind you on the couch while the TV plays a movie that neither of you are really paying all that much attention to. The light illuminates you both, setting the mood in the otherwise dark room, while Kirishima fondles your breast absent mindedly. He's just doing it for fun - just because it's there, really, but that doesn't explain the sudden twitch you feel at your lower back.

Oh.

"Hey babe, what's up?...

"I want-... I- I want-.… To fuck them..."

Sorry, what?

Surely he doesn't mean...

"You wanna fuck who, now?"

He just snorts and mumbles into the back of your neck, giving you goosebumps as you feel his chest rumble against your back.

"No, silly... I wanna fuck your tits..."

Huh. Well at least you're not stunned and confused anymore. Now your just stunned. The idea seems fun, and the thought does bring a familiar heat between your thighs. You just wonder what's brought this on.

In reality, he's always fantasized about fucking your tits. It's the very image that gets him off when you're not there to help him, but he's finally got the confidence to ask for it now.

"... Alright. I don't see why not~"

He's almost cries at the relief of not being rejected immediately, rolling on top of you before you can say anything against it. Suddenly, your chest is met with cold air as you're stripped of your shirt, your bare breasts being massaged and pushed together.

He just loves to squeeze and play with them, though he wastes no time unzipping his fly and pushing down his pants. His cock, already at full mast, is an angry red at the tip, leaking precum all over his hand while he moans and shivers, staring at your tits like a man hypnotised.

You slowly push your tits together for him, giving him a teasing smirk as he practically drools, too aroused to be his usual, gentlemanly self. In seconds, he's kneeling over you with a hungry look in his eyes, pressing his cock between the little valley between your breasts, groaning at the contact. Pleasure shoots up his spine as his head is flung back, his eyes tearing up and his hips rutting shakily.

Each time the little head peaks out from the top of your breasts you reward it with a lick, and he practically falls apart exactly like you wanted him to. He's never came so quickly in his life, but you don't mind even as your face and chest is smeared in his spend.

He almost faints.

A/n About mha but there's so many jjk characters I feel like would do this :3 so sorry for any errors.

Thinking about having a Pro-hero boyfriend that everyone loves, they adore him, he's just so sweet and kind yk?, literally would do anything to protect the civilians, helping people and saving them from villains. Practically risking his life every single day for others with a smile plastered on his face. Everyone looks at him with pure adoration and honor.

But behind closed doors when he's with you, he's not so nice and sweet when he has your body folded in a mating press, heavy balls slapping against your asshole as he's stabbing his cock into you in a reckless pace that has your cunt gushing and creaming all over his length, he makes sure that he's balls deep buried into your cunt to the hilt with every hard thrust. Every. Single. Time, when he's frustrated because of work, whether it's because a villain got away or he didn't get to save a civilian, he takes it all out on your poor cunt as soon he gets home, he doesn't waste a second. He doesn't even bother getting his hero costume completely off before he's rutting his hard cock into your tight hole, splitting it in two around him while he's stretching you apart.

He thrusts himself so fucking hard into you that he might almost break you one day because of how reckless he is with your poor little body, training and working out is a serious thing for him so him being so fucking bigger and stronger than you, even than a normal man is no surprise, matter a fact he practically has the body of a fucking Greek God so manhandling you into whatever fucking position he felt like bullying his cock into you in and fucking you stupid in, wasn’t that difficult for him at all.

He loves having his way with you, it's almost sadistic how he laughs and mocks you every time he has you blabbering a bunch of nonsense on his thick cock with fat tears leaking out your eyes, big strong arms flexing against you, displaying his ripped muscles while he's holding your body effortlessly as he's fucking you in full nelson, your pathetic little babbles and moans filling his ears as he's licking your tears away. Hell, he'd even have you screaming his Hero name while he has your filthy cunt making a mess all over his cock.

And Oh there's no words to describe how much he loves making you nervous and teasing you whether it's circling his thumb over your asshole, and poking it ever so slightly so he can hear the shifting of your moans, making you overthink that he's going to force his thumb inside of you, then he just chuckles and moves his thumb towards your clit to rub sloppy circles on the sensitive bud. Or whispering a bunch of nasty shit to your ear while he's ruining you because he knows how much that shit drives you crazy.

"Fucking hell I'm gonna ruin you, gonna reshape this cunt to the size of my cock so it could be perfect just for me, you get that? You belong to me".

"Such a good little cumslut f'me aren't ya baby? so fucking warm and tight for my cock".

"Fuckkk princess no one can fucking ruin this cunt like I can, your daddy's one of the best fucking heroes, only I can fuck you this good and stupid, yeah?"
