'Smolbutmighty'. The cam boy's screen name doesn't make sense to Katsuki (who doesn't see how an AM reference can be sexy) until he actually clicks on the stream. The cam boy is petite, so much smaller than him, but his ass and the dildo he rides... both of them are /huge/. +

Katsuki's arrived too late, as the green-haired twink bounces wildly on the dildo, driving himself to a whimpering orgasm as his small dick leaks with cum. The lewd expression on his face as he cums has already convinced Katsuki to look into this cam boy, but when the petite man+

announces that next time, they'll be in for a special surprise, Katsuki is sold. There's still the issue of his erection when the stream ends, so he clicks on the cam boy's profile. 'Midoriya Izuku, aka smolbutmighty'. There are a number of videos, ranging from him riding +

various dildos (that he's all given names to, the nerd) to twerking in lingerie. But Katsuki settles for a piece in a maid outfit, the too-small skirt riding halfway up...uh, Deku, was it? Katsuki can't be assed looking it up... the skirt riding halfway up Deku's fat ass as he +

pushes the wide butt plug in, whining softly as he takes the whole thing. It's easily the size of Katsuki's fist, but Deku takes it like his ass was /made/ for it. So, Deku likes it big, huh? Katsuki grips the base of his thick cock and starts stroking up and down the length of+

it, wondering how the pretty cam boy would react if he saw Katsuki's dick. Nah, scratch that, he wonders how Deku would react if he sat that big ass on his lap and fucked him until he screamed. The thought has him stroking himself harder as the recorded Deku on screen grinds +

his ass against a pillow, pushing the butt plug further up his ass. And fuck, on top of that, the sweet-faced cam boy has a fucking /filthy/ mouth. "Oh, hnn, yeah, just like that," he moans, the frills of his skirt framing his ass as his stockings strain around his thick +

thighs as he rides the pillow at a fast pace, "ohh, fuck, fuck, I wish someone would /fuck/ me and /fill/ me up with their big, /thick/, cock, ohhhh-! Yesss, it feels so /good/, I bet you can't stop, ahh, staring at m-my ass in a tiny skirt, r-right? Bet you'd l-love to slap my+

big, /fat/, ass, ohhh, bet you'd love to grab m-my hi-hips and /fuuuck mee/, o-ohh..."
He slaps his own ass as he rides the pillow even faster, and Katsuki gulps as he picks up the pace himself, stroking his cock and imagining all the dirty things that Deku's moaning about. +

Usually, it takes four or five videos to bring Katsuki to an orgasm, but with Deku, he cums even before the recorded cam boy does himself. Deku's definitely a new favourite, and Katsuki decides that he'll join Deku's Patreon if he likes the upcoming video. He checks out the +

cam boy's YouTube channel in the meantime, surprised to find out that Deku runs a pretty popular theory channel. It's evidently not as profitable as Deku's porn account, which has millions of subscribers, but it's doing pretty well, and Katsuki discovers a different side of Deku+

on it. The Deku he meets on the theory channel is witty, funny and sweet as well as cheeky, but most of all, he's insanely intelligent, and Katsuki thanks whoever's out there for Deku making the decision to go into porn alongside his usual hobbies. Because fuck, Deku's just his +

type. It's insane that he's found someone so damn perfect. The only thing better would be actually meeting the cam boy, but he knows that's impossible. He's happy with this, and he's full of anticipation as he lays down on his bed on Saturday night, his laptop open in front of +

him. He's one of the very first people on the stream, so he's there when Deku introduces what he promises will be an amazing night.
"I've got it all set up," he says, wearing a modest hoodie, "and you can only see my torso right now, but I'm sure all of you will /love/ the +

outfit I've chosen. As soon as a few more people arrive, I'll show you the thing I've set up, but I think I should start by getting rid of this hoodie and revealing my clothes... But I might need some motivation, if you know what I mean."
'take that hoodie off, baby, i'm sure +

ur feeling warm', an anonymous user writes. *ANON TIPPED $40.*
Deku giggles.
"Thanks!" he says, small hands curling around the hem as he stretches and pulls the hoodie off to reveal a white bra and a frilly collar. He pulls some strings behind him too, and bunny ears pop up too.+

Tips begin to pour in steadily, but it's not until another user types in, 'stand up and show us your beautiful big ass' (*ANON TIPPED $80*) that Deku blows a kiss and stands up, revealing a tiny white skirt to match the top piece. It doesn't even attempt to cover his ass, laying+

over his flaring hips, accompanied by a thong that disappears between Deku's thick ass cheeks. He shakes his ass playfully before sitting back down and giving the camera a sultry smile. "Let's /really/ get started, okay?" +
[the outfit: https://cdn.shopify.com/s/files/1/2417/6849/products/bunny-scout-lingerie-set-blue-lace-bow-rabbit-crop-tops-intimate-wear-ddlg-playground-522_600x.jpg?v=1590284301]

He reaches forwards and tilts the camera towards the side of his bed, and Katsuki's breath catches in his throat. A fucking machine. And not just /any/ fucking machine. A fucking machine with an 11-inch dildo attached to it. If tips were pouring in before, Deku's practically +

drowning them as he sits on his bed, explaining the product as he absentmindedly rubs his hands over the little bra. "So, most of you recognise this as a fucking machine, but this has two extra functions: extreme mode, where it'll absolutely /pound/ my ass, and cum mode, where +

it'll fill me with cum until I say stop. And because I bought this for all of you, /you/ can determine when it stops filling me up. But I'll explain that more in a bit. For now... I've prepped my ass, but I think I should prep the dildo. Should I use my hand or my mouth?" +

'Use your mouth, precious', izukulove6900 types. *ANON TIPPED $80*.
"Mm, mouth it is," Deku nods, smiling almost innocently. He gets on his knees in front of the dildo, taking it in both of his hands and leaning down to guide it to his mouth. The way his lips stretch to wrap +

around it has Katsuki pulling out his dick and beginning to stroke. Deku takes more and more of it down his throat, until he's /somehow/ taking the /whole damn thing/ like it's natural to him. He moans as he bobs up and down, coating the huge dildo in a thick layer off spit +

before he finally pulls off it, spit dripping down his chin as he swipes it off with a thumb whilst staring seductively at the camera. Deku could be anywhere across the world, and yet Katsuki feels his gaze pierce him. /Fuck/, what he'd give to fuck the perfect little pornstar. +

But here it is: the main event. Deku turns around and gets on all fours so that the dildo lies on top of his thick ass. Katsuki could stare at it all damn day. It's so perfectly round, firm and toned. He wants to grab handfuls of it, he wants to slap it, he wants to see it +

(hey google: how do you stab the tweet limit)

(continuing immediately, I'm not even at the good part after the fucking machine goddamnit)

jiggle as he fucks him, but for now he'll have to settle for watching as Deku slowly starts to take the dildo. He pants softly, his mouth falling open of its own accord as he rocks back and forth, more and more disappearing into his wet, open hole as he moans. Katsuki's seen +

recorded videos of him doing the exact same thing, but seeing it in real time just makes it even more impressive. His ass wobbles as he takes the enormous cock like a pro, and Katsuki has never been more turned on in his life, but he can't cum now, as much as he wants to as he +

watches Deku's ass swallow up all eleven inches. At last, it's all in, and Deku whines as the money rolls in.
"O-Ohh, it's so big, but I want more," Deku gasps out. "I'm such a /slut/, aren't I? But it feels so, so gooo/. Should I turn the machine on? See how good it really is?"+

'Fuck yeah, baby, go for it.' *ANON TIPPED $80*.
'Oh, good boy, you can do it!' *ANON TIPPED $100*.
Deku chuckles breathlessly.
"I think I need a little more motivation than that," he hums, and Katsuki, who's been waiting anxiously for Deku to just get /fucked/ already, finds +

his hands flying across the keyboard before he realises what he's doing.
'You don't need shit, you greedy little slut, I bet you can't wait to be pounded like you deserve to be. Just get the hell on with it.' *KINGKATSUKI TIPPED $250*.
Deku blinks, caught off-guard, before a +

smile slips onto his face.
"Oh hmm, looks like I've got myself a sugar daddy," he winks. "But King Katsuki... I think /Kacchan/ sounds better, don't you? So whatever you say, /Kacchan/."
He turns the machine on, true to his word, but it's obviously on the lowest setting. Katsuki+

can hardly believe that the cam boy acknowledged him, let alone gave him a stupid, /provocative/ nickname, so he's sure as fuck going to push his luck.
'Cheeky little slut, aren't you? Bet all the bastards here tell you how good you are, and how well you're doing, hah? Yeah, +

well I'm not buying that bullshit. You're a pathetic whore, you know that? Flashing that gorgeous big ass at us and doing nothing with us. Show me what you're made of, /Deku/, go straight to the highest setting'. *KINGKATSUKI TIPPED $350*.
Deku bites his lip and moans softly as +

(alright, I'm gonna scream, my mother appeared behind me as I'm not at uni at the moment and I jumped out of my soul and closed the tab, and now my progress is GONE, but I'll be hopping right back on it bear with me)

he reads the message. Katsuki knows it's a /real/ moan, not something for show. He's been watching a lot of Deku's videos the past few days and he's discovered that Deku must like being degraded. So that's exactly what he'll do.
"Whatever you want, Kacchan," Deku breathes, +

pausing for a moment before closing his eyes and flipping a switch. The machine hums as it comes to life, the leisurely pace picking up to something relentless as it goes faster and faster and /faster/. Deku's ass jiggles and shakes uncontrollably as he's ploughed without mercy,+

his tiny little skirt being buffeted up by the action. Katsuki could stare at it all day, but fuck, it turns him on so much. He loves how firm it is, he loves how round it is, he loves how big and fat it is. Katsuki has always been an ass man, but everything pales in comparison +

to this. Deku has the best ass Katsuki has ever seen. Watching it bounce on the enormous dildo has him reaching a hand back to his trousers and stroking vigorously, Deku's moans filling the room from the laptop as his eyes roll back and drool drips down his chin.
"K-Kacchan, oh+

fuuuck, I wanna move, I wanna grind back against it, I want it to fill me up with so much cum that I can barely move, Kacchan, /please, please, please/!"
Katsuki obliges him, telling him how good his ass looks now that it's finally being put to good use, how much of a worthless +

slut he is, and then finally, how much he wants to see Deku shake his ass against the fuck machine. He tips generously, drowning out everyone else's meagre offerings. Deku's more than happy to listen, and as erotic it was seeing Deku's ass bounce involuntarily against the thick +

dildo, it's even more satisfying seeing him shake his fat ass against the machine and moan Katsuki's name. It's like he has his own private show, and it's honestly the best stream he's ever been a part of. Obviously, it's not a private show, and Deku does take a break to indulge+

his other viewers, but Katsuki can see in his eyes how much he wants Katsuki's instructions, especially after he cums and Katsuki tells him to /keep fucking going, we're not here for you, slut/. And then it comes to the point where Deku slows the dildo down and says, panting, +

"Mmm, I don't know about all of you, but I want to try out the cum option, now that I've tried out the extreme option-" Katsuki had come himself during the extreme option, because Deku had looked /so fucking delectable "-so this is how it works. You start tipping, it starts +

filling me. If the tips stop, even for a moment, the machine stops, and we're done for the night. Make sense? Because I'm ready when all of you lovely people are... especially you, Kacchan."
Katsuki grins. Deku's gonna regret challenging him like that.
The tips start off at $80,+

and after turning the speed up, Deku presses the cum option, crying out as the dildo starts to eject artificial cum. Fifteen seconds later, the tips are still rolling in, and Deku's whimpering, telling his viewers how he wants to be filled up /even more/, he wants it spilling +

from his slutty ass, dripping down his thick thighs. At forty five seconds, the cum is steadily dripping down his thick thighs as promised, and Katsuki hopes that Deku is starting to realise his mistake. As much money as he's making, he's starting to /really/ fill, an honest +

whimper escaping his mouth as he says, "O-okay, everyone, th-that's enough, any more and it'll sh-show, ohhh, mmm, fuck, why does it feel so /hot/?"
'Because you know you wanna be filled up until it's empty,' Katsuki types. *KINGKATSUKI TIPPED $500.*
"N-No, please," Deku begs, +

hands moving to his stomach. Katsuki follows his small hands to see, to his delight, that it really /is/ showing. Katsuki takes a morbid pride in seeing big things filling Deku's tiny body, and he keeps the money rolling. In the end, Deku's tummy ends up rounded when the +

fucking machine finally empties. He's made a /fuckload/ of money from Katsuki alone, let alone from everyone combined.
"Mmm, you guys really went /Plus Ultra/, didn't you?" Deku giggles drowsily, lying on his side as he says his farewells to the camera. "I'd ask you all if you +

liked your surprise, but I /know/ you did, haha. If you really want to show your appreciation though, you can hop over to my Patreon or my OnlyFans, or maybe even my YouTube channel! Anyway, thank you, either way. I love all of you, know that?" He babbles on sentimentally for a +

little more, something Katsuki finds strangely endearing (usually he'd have clicked off by now), before saying goodbye and ending the stream. Katsuki's about to go straight to his Patreon and OnlyFans (how did he not hear about the second one sooner!?) when... a message pops up +

in the corner. Katsuki freezes.
*(1) NEW PRIVATE MESSAGE FROM: SMOLBUTMIGHTY*
Hands shaking, Katsuki clicks on it, half expecting clickbait. Instead, he sees:
SBM - Hiya, Kacchan! Thanks for all your support tonight

(I'm going to continue writing in about half an hour or so, I need a break I hope you all like it so far, I know it's super self indulgent sorry for any mistakes too!)

Katsuki types out a careful response.
KK - s'nothing, u looked hot af
SBM - all thanks to your dirty talk you're really good at it, you know
KK - oh yeah? ur damn right i am
SBM - I've never offered this to anyone before but... would you like a private show? Just us two? +

Katsuki would be over the /fucking moon/ for one, but he's not gonna let that on so easily.
KK - u asking 4 more money?
SBM - omg no, that's not what I meant at all!! You just... know how to turn me on. It's hard to find someone like that. You can say no, of course! I understand+

that you might not be comfortable.
KK - chill, i'd be down 4 it
SBM - Really!? Yay!
KK - how do u know i'm not some old creepy dude tho
SBM - ...well, I don't know how you look so I can pretend you're hot
KK - you know, i can do u one better
SBM - How?
KK - video chat+

me. U put on ur private show for me, and I'll give u something good to look at.
SBM - That's a high opinion you habe of yourself. You think I'd be turned on?
*KINGKATSUKI HAS SENT A PHOTO*
The photo is a full bodu shot of him in the mirror, wearing clothes bc he respects that+

Deku might not want an unsolicited dick pic.
KK - my dick is as good as i look, promise
SBM - fkfkfkgkkfdkskskg how are you literally perfect!? I accept, we'll video chat. Is there anything you want me to prepare?
Katsuki's mind automatically flits to an old video of Deku's. +

It's one that hasn't got a lot of views, probably because Deku was just starting out. In it, he forces trousers three sizes too small over his lingerie clad ass, then proceeds to do everything from pole dancing to gymnastics to twerking to burst the seams. Once they break, he +

rips them open further and sinks down onto his usual big size of dildo, fucking himself to orgasm. It's Katsuki's absolute favourite video, and he hates the fact there's only one like it.
KK - i want u to gey everything u need to recreate ur 'Showing You Just How Big My Ass Is' +

video
SBM - I like you even more now I loved making that video, I'd be more than happy to recreate it! Is tomorrow at ten p.m. okay?
Katsuki smiles.
KK - fuck yeah
SBM - See you then, Kacchan~
KK - likewise deku
***
Katsuki jerks off five times before their set time just+

thinking about how fucking hot it's gonna be. He's set aside a ton of cash for Deku on a separate card, even though he knows that Deku's in it for more than the money. He's a real slut who wants to cum as hard as he can. And just like last time, Katsuki's gonna give it to him.+

Katsuki gets hard even as he's setting up the webcam. Sure, it's nothing professional like Deku's setup, but it'll do well enough. The video chat starts off innocently enough, with both of them chatting for a while. Deku doesn't shut up about how "gorgeous" Katsuki is, so +

Katsuki keeps telling Deku how perfectly pretty he is. They flirt like teenagers, and it finally gets to a point where Deku holds up a bag and says, "I got yoga pants four sizes too small instead of three, I hope you don't mind..."
"Your ass is going to hate you," Katsuki snorts+

before adding, "I only mind that you haven't put them on yet, Deku."
His hand moves to the keyboard.
*KINGKATSUKI TIPPED $400*.
"K-Kacchan, don't throw your money around like that!" Deku flails, so Katsuki tips him another $150. "That's it, I'm turning payments off!" +

"So this is a free show?" Katsuki grins. Deku matches his grin.
"Oh, you'll be paying with that mouth and body of yours, I'm sure," Deku purrs, before turning around so that Katsuki has a clear shot of Deku's ass in tiny green lace lingerie. He bends down and easily pulls the +

yoga pants up to his knees. The problem occurs when he reaches his thick thighs. He tugs at them, bouncing his legs from side to side to pull them further up slowly.
"Mm, yeah baby, keep going," Katsuki encourages. "Tell me how it feels, tell me just how big your ass is." +

Deku's reached the bottom of his ass now, but the yoga pants are firmly stuck, digging into the round fat of Deku's big ass as he struggles to pull them up.
"Hnn, Kacchan, they're too /tight/ for my big fat ass, I don't think I can do it..."
"Yes you can, baby," he croons, hands+

reaching automatically for his keyboard though he can't tip. Then he realises something, pulling down his trousers so that he's left in his boxers. "Look back at the screen, look how hard you're making me."
Deku looks back over his shoulder and bites his lip, eyes wide. +

"K-Kacchan,y-you look so /thick/, I wanna see all of it," Deku pleads, his ass bouncing as he tries to pull the fabric up further.
"I'll show you if you get those yoga pants on," Katsuki promises. A glint of determination appears in Deku's eyes as he jumps a little, ass bouncing+

even more as he shimmies the pants over the widest part of his ass. Finally, /finally/ they're on, the hem dipping into a curve as the pants strain to hold all of Deku's fat ass. Katsuki pushes his boxers down to reveal his big, throbbing dick, and Deku /moans/ when he sees it. +

"Hnn, Kacchan, I wish I was there so you could bounce me on your huge cock, it looks so /delicious/," Deku whines as Katsuki begins to stroke it leisurely.
"Oh yeah, you /know/ I'd fuck you into oblivion," Katsuki boasts. "But for now, I'm already missing your big, slutty ass. +

Get rid of those yoga pants, would you?"
"My pleasure," Deku grins, shifting the camera so a pole is visible in the background. He stands in front of it with his ass facing Katsuki, and Katsuki knows that Deku will tesse him before he actually tries to tear the seams. But when +

Deku starts twerking like /that/, Katsuki doesn't care, his hand gripping his dick and stroking it faster as he watches the show. Deku makes his ass cheeks clap even in the tight pants, his own hands grabbing and slapping his thick ass as it jiggles and shakes.
"Mm, you like +

that, Kacchan? Like seeing me twerk like a little whore so that I can break through these pants and fuck myself for you? You look like you're addicted to my ass, the way you stroke your huge cock, Kacchan..."
He leans forwards teasingly so that a few holes begin to rip along the+

seams, exposing some of his smooth skin, before he giggles and moves to the pole, pressing his ass against that instead. The pole wedges itself between Deku's fat ass cheeks and Katsuki is glued to the screen as he begins to stroke harder. He's already close, and they're not +

even halfway through. He's screwed, but he can't stop himself when Deku grinds his ass against the pole and winks at Kacchan.
"You look like you wanna see my ass already," Deku teases.
"Fuck yeah," Katsuki says, unashamed. "I wanna hear you talk about how good it feels when +

you split your seams because your ass is just /too damn big/ for those shitty yoga pants to hold. Do it, Deku."
Deku moves in front of the pole again and spreads his legs apart, massaging his ass with his small hands as he says, "I bet you could treat me right, Kacchan..." +

(Okay so I said I'd finish it today but I have to get up in five hours so I'll finish it tomorrow, haha thank you for sticking with me for this long, I hope it's good! As always, sorry for any mistakes I love you all!)
