KINKTOBER DAY 12: Sexting/ Filming
Bkdk highschool AU where Katsuki's the star jock and Izuku is the head cheerleader. Katsuki is built like a truck, with broad shoulders and a wide chest, whilst Izuku is small and lithe, with a sweet face and a big, round ass. Their rivalry+

is famous school-wide, and it's more unusual to see them getting along than it is to see them bickering about something totally irrelevant, like who should have the last carton of strawberry milk from the vending machine, or whether the answer is A or B. But when it comes to the+

pitch, their bickering takes on what can only be described as unresolved sexual tension. It goes from arguing about a mathematical formula to Katsuki flexing his muscles at the crowd with his eyes locked on Izuku, with Izuku kicking his leg up high enough that his skirt flutters+

up to reveal tantalising skin. Katsuki will grin and wink at Izuku, and Izuku will flash him a sweet smile, underpinned by the lust in his eyes.
"Dude, you two have been eye-fucking for how long now?" Kirishima quips after one particularly heated match.
"Yeah, you two should go +

get a room," Kirishima's dumbass boyfriend Kaminari joins in.
"Shut the fuck up, it's not like that," Katsuki says, taking a sip of his drink. Deku walks by at that moment, blowing him a kiss and exaggerating the swish of his wide hips as he disappears around the corner. +

Katsuki practically forgets how to drink, water spilling from his mouth as his jaw drops.
"Sure it isn't," Kaminari sniggers.
Izuku's doing his cooldown stretches when Uraraka asks him, "So, what's going on between you and Bakugou?"
"What do you mean?" Izuku says nonchalantly, +

touching his foot to his head and then kicking back into a graceful bridge position. He twirls out of it, careful not to exert himself too much as he slides into a split, leaning forward to rest his chin on his palms.
"The sexual tension! Do you honestly not see it?" Hagakure +

exclaims, from where she's sat in a butterfly position.
"W-What sexual tension?" Izuku blushes, flustered.
"Aha, there!" Mina points triumphantly, wiggling her finger. "You wouldn't be blushing unless you knew we were right!"
"I don't know what you're on about," Izuku defends, +

and Kacchan chooses that moment to walk into the sports hall, shirtless as he asks: "Hey extras, has anyone seen the coach?"
"Kacchan, put a shirt on!" Izuku cries, affronted.
"Oh shut up, nerd, you're into it," Kacchan jeers.
"You wish," Izuku retorts, eyes sparkling +

nevertheless.
"I don't need to wish when it's true," Kacchan throws back immediately.
"Well, then here you better be wishing on all the stars," Izuku grins, biting as his bottom him. He's still in splits and he wiggles his hips teasingly as Kacchan rakes his eyes over his body.+

Tsuyu clears her throat.
"I believe I heard one of your friends say this earlier," she says, holding the frog position whilst she talks, "but you two should really find a separate room and resolve this privately, not in front of an audience."
"Resolve /what/, frogface?" Kacchan +

huffs.
"The sexual tension!" the girls yell at the same time. Izuku wishes the ground would swallow him up, and if Kacchan's blushing face is anything to go by, he feels the same embarrassment. He leaves without even getting an answer to his question, and Izuku groans, sinking +

further into the ground.
He recovers by the time he gets home, flopping on his bed and opening Snapchat. He's got a few messages from people, none that he feels like opening. But then he notices the blue of a new chat from Kacchan, and his fingers move to click it before he can +

stop himself. Izuku sighs as he responds to Kacchan, wondering why some people think texting 'wyd' after not messaging in a month works. The conversation takes a weird turn almost immediately, and then when Izuku figures it out, he's left on read. Wow. It must have been one of+

Kacchan's friends. Izuku locks his phone and places it carefully on the nightstand. He really should change out of his cheerleader outfit, but as he runs his hands across his body, he notices how /good/ he looks in it today. No wonder Kacchan was staring. These moods are rare, +

moods where he actually feels attractive enough to want to /do/ something about it, like film it or something. And why not? He reaches for his phone, opening Snapchat again. He can take a few videos, a few pictures, save them to his private Memories, and then change. It's not +

like anyone will see it anyway. Izuku's pretty protective of his phone. He lies on his back, biting his lip with one hands pushing his crop top up so that he can pinch his own nipple. He angles the camera with the other hand and takes a few pics. His expression morphs from +

biting his lip to rolling his eyes back as he plays with his nipples. As he scrolls over the photos, he's filled with even more confidence. He looks /good/. He rolls over, spreading his legs and arching his back as he pushes his ass up in the too-small cheerleader outfit. He +

presses down on the record button, biting and licking his lips seductively towards the camera as he starts to twerk, shaking his big, round ass in his cheerleader skirt and watching it get buffeted upwards until it's hiked around his hips, green thong visible as he makes his fat+

ass cheeks clap. It's a skill of his known only amongst the cheerleaders: he's /amazing/ at twerking. Maybe it's because he has a big, wide ass, or because he's been practicing for years, but he can shake and jiggle and twerk like a pro. And the /sensation/ of skirt being unable+

to cover his ass, of his ass jiggling against itself... it /turns him on/, and he moans softly, arching his back further to give the camera a momentarily better view before he smiles with faux innocence and stops recording. He knows that no one is going to see the perfect video +

of him twerking, but he can't help but caption it with a 'you like it when I twerk my fat ass for you, don't you baby? '. He goes to save it when his mother knocks at the door. He yelps and drops his phone, hurriedly calling out, "One second, mom!"
"Oh no, don't worry about +

opening the door, honey," his mother responds. "I just wanted to let you know that dinner will be ready a little later today. You can snack on something if that'll help!"
"I-I think I'll be fine," Izuku calls through the door, sighing and picking up his phone once he hears his +

mother's receding footsteps. Has he lost the video? God, he hopes not. It was probably one of the best he's ever-
Kacchan
Delivered . 28s
Izuku whisper-screams, frantically clicking at it as if it will unsend. When that doesn't work, Izuku starts planning a way to steal+

Kacchan's phone. But as he's thinking, he sees the inevitable:
Kacchan
Opened. 7s
And then, when Izuku can't panic anymore, he sees:
Kacchan
New Snap. Just now
+

(The people watching my stream have heard me complain about the tweet limit enough, I will spare them this tweet - continuing in a few minutes! Just gonna make some tea and end the stream!!)

He opens it, holding his breath. Half of Kacchan's face is in shot, the rest of the photo focusing on his chest and arms in a black tank top. The caption reads, "Fuck, Deku, feeling ballsy today, aren't we? That ass looks delectable, I wanna see more". Izuku is about to respond +

with an awkward explanation of how he didn't actually mean to send the snap, only to notice Kacchan has sent another snap. It's a full shot of his face this time, with a cocky (and undeniably sexy) grin on his face. The caption here reads: "Unless you sent it accidentally, in +

which case I'm never gonna let you live it down, dumbass".
And Izuku isn't going to let /that/ happen. Besides, Kacchan seems genuinely... interested. He's lying to himself if he says that he hasn't been thirsting over the perfect blond for years. This is a unique opportunity. +

Why not take it?
He double taps Kacchan's name, raising the camera screen that pops up above his head so that Kacchan can glimpse his fat ass. He locks eyes with the camera and bounces his ass up and down so that sinks and pushes against the soft mattress, before captioning the +

video, "If you wanna see my delectable ass, I wanna see if the rumours are true about the size of your cock, Kacchan".
Kacchan responds in less than thirty seconds, with a video of him trailing the camera down until he reaches his boxers, cupping his clothed erection and toying +

with it so that he can see the outline of his cock. And fuck, the rumours were right. Izuku thought they might be exaggerating, but they're actually /understating/ how big it is. And /thick/ too, even through his underwear. Izuku moans quietly to himself as he watches the video +

a few times over before placing the camera behind him so that it has a clear view of Izuku's fat, around ass. The fabric of the pleated cheerleader skirt only covers half of it, and as Izuku starts to twerk, using a shortcut to records hands-free, it slides higher and higher +

until Izuku's big, smooth ass cheeks are exposed to the camera. His thong is swallowed between his thick ass cheeks, so he pulls it out, snapping it back against his ass where it digs into his thick cheeks. Captioning the video, "I wanna see more, Kacchan, that's not enough to +

get off to, is it?", he sends it, waiting for a response. A minute later, Kacchan still hasn't responded, and Izuku's starting to get nervous, when the purple message appears on his screen. He clicks on it to find a video of Katsuki, his big, thick dick in the foreground as he +

jerks himself off, sliding his hand up and down his heavy length.
"Fuck, baby," the caption reads. "I want that ass against my face, I wanna pound it into the mattress, I wanna squeeze it and spank it so goddamn much."
Izuku can feel himself leaking pre-cum against his lingerie +

as he sets the phone down again, having looped the video over and over again. Kacchan's so /hot/, a red flush on his face as he fucks into his hand. Izuku starts to record himself again, grabbing two handfuls of his ass and squeezing before dropping them and pushing his ass +

forward. He spanks his own ass over and over again, moaning as his cheeks clap against each other.
"Like this, Kacchan?" is all he says, but Kacchan responds with a video of him jerking his own dick even faster as he growls:
"Fuck, just like that, baby. You sound so slutty and +

gorgeous, whining and moaning for me like that. If you were here I'd make you fucking /scream/, you know that?"
The caption reads: "Finger yourself for me, Deku, I wanna see how slutty my princess is."
And when Kacchan sends him something like /that/, who is Izuku to say no? +

He slides his thong down halfway so that his ass bulges out, making it look even bigger than it already is (which is a feat, because everyone knows that Izuku's ass is /huge/). He grabs the lube, making a show of slicking his hands and drizzling some over his ass so that his +

fat ass cheeks are all shiny, before carefully spreading his ass. He presents his tight hole for Kacchan, bringing his ass closer to the camera as he pushes one finger in all the way. He whimpers as loud as he can without being heard by anyone at home, bouncing against his +

fingers as he fucks himself.
"I can take my fingers easily, Kacchan," he shakily taps out. "But it's the 10 inch dildo I have that you'd wanna see my big, fat ass bounce on."
Kacchan replies almost immediately this time, his face and delicious, wide chest in view as he says: +

"Deku, I swear to fuck, if you film you riding and cumming on that dildo, I'll come over and pound you into the mattress," Kacchan promises huskily. "I mean it, as /soon/ as I fucking have the video. Deal?"
Izuku's eyes widen. Kacchan? Fucking him? For real, with that dick of +

his? Izuku has never said yes to anything so quickly.
"Good," Kacchan types in response. "I'll be waiting then, gorgeous "
Izuku reaches for the dildo under his bed, moving to the camera app and turning his camera sideways so that it captures all of Izuku's sizeable ass. +

He places the dildo on the mattress, and clicks record. Making a show of stretching himself, he slides his fingers in and out easily, pumping lube into his ass and then squeezing his ass cheeks together so it dribbles out like cum. He spanks himself a few times, moaning +

shamelessly before pouring lube over the dildo and reaching back to stroke it, even though his hand can't quite make it around the whole girth of it. Once it's all slicked up, he raises his powerful thighs and lines the tip of it up with his hole... before /slamming/ down on it +

in one go. He arches his back, releasing a long, low moan as he takes the whole thing like a pro, his tiny stomach bulging from the size of it.
"Kacchan, it's so biiig," Izuku groans, panting heavily. He spanks his ass a few more times, rolling his eyes back and starting to +

swivel his hips. Once he's set a slow rhythm, he lifts himself up and pushes back down again, whimpering pathetically as he does. "Ohhh, it's stretching me so /much/, Kacchan, it feels so /goood/."
He pumps it in and out and in and out until he's bouncing on it properly, filthy +

sounds spilling from his lips as he twerks and shakes his ass on the thick dildo, fucking himself thoroughly. He throws his head back, mouth opening in a slutty pant as he spreads his legs wider and forces himself to go faster and faster.
"Mm, you love watching me twerk like a +

slut on this big, thick dildo," Izuku purrs, grabbing his ass and spreading his cheeks to show off to Kacchan as he continues to wreck himself, moving closer and closer to cumming. "Mmm, hurry up and come over so you can fuck me the way you should, Kacchan, I want it so /bad/!"+

He starts riding the dildo in earnest then, rolling his hips and switching the angle so that he ram into his prostate, fucking himself mercilessly. His eyes roll back properly, tongue lolling out as he drowns in pleasure.
"K-Ka-Kacchan, I-I'm gonna- I'm gonna- Kacchaaan, fuuck!"+

(Not today, tweet limit, not today, he's already orgasmed, leave him alone!)

He folds over himself, thighs shaking as he shoots long, white strips of cum all over his legs and pillow. He breathes heavily, reaching back to blow Kacchan his signature kiss before ending the video. Now that's orgasmed, he's starting to come to his senses, or rather... He's +

starting to doubt himself. But before he lets it take over, he opens their messages and sends the video. He can worry once it's done. Kacchan opens it, and Izuku worries his bottom lip, staring at the phone for a reply.
Kacchan saved a video to Camera Roll!
A purple +

video snap appears, and Izuku opens it frantically.
"Fuck, I'm saving that to watch every fucking time I'm horny," Kacchan says, sliding on his coat. "I'll be there in five. If you think you wrecked your ass with that dildo, oh princess... I'm gonna make sure you can't fucking +

/walk/."
"I'll be looking forward to it," Izuku whispers to himself as he types out the same thing as a text. When he hears the doorbell five minutes later, he can't help the smile that covers his face.
***
(Katsuki lives up to his promise, making Izuku cum over and over again +

the whole night. They have to be quiet, the same way they do when they fuck under the bleachers, the bathrooms, or empty classrooms, etc. every day after. They can't keep their hands off each other, whether it's cuddling or fucking or bickering. They're the perfect couple.)
