"So, as you can see, we've got a bit of a situation on our hands. But I know how much you've always wanted Kacchan to become a Pro Hero. I figured I'd ask you first how we could best… remedy the situation."

Mitsuki Bakugo, mother of Katsuki Bakugo, is appropriately pale as she flips through Izuku Midoriya's notebook. Sat across from her, the young man does his absolute best not to fidget or squirm, just as he did his best to keep the tremor and stammer out of his voice while speaking just now. This whole situation… it was a bit of a risk he was taking, but at the same time, it felt like the only path forward for him.

Finally, the MILF seated across from him speaks up, her red eyes wide as she looks over the detailed journal he'd kept of her son's bullying for years and years.

"I-Izuku, this is…"

Smiling a wan smile, one that most certainly doesn't reach his eyes, Deku, as he's known to many, finishes for her when she trails off.

"Irrefutable? Unconscionable?"

A shiver runs down Mitsuki's spine, the Grade A MILF biting her lower lip in visible concern. And she SHOULD be concerned. As much as Deku had always been a Hero Fanatic, keeping notebooks and journals on both real heroes as well as hero concepts he'd come up with, he was also just a diligent notetaker in general.

Early on, in the days when Kacchan (Mitsuki's sun, Katsuki Bakugo) had first started bullying him, Deku hadn't even recognized it as bullying at the time, leading to a lack of evidence of those initial incidents. 'Luckily' for him, Kacchan certainly hadn't let up, and even Deku had been able to eventually get it through his thick skull that his former childhood friend had turned on him.

After that point, it'd just become… simple for Deku to record what Kacchan did to him and his things on a daily basis in one of his notebooks. Like a cross between a diary, scrapbook, and journal, the notebook that Kacchan's mom was reading right now was a damning piece of evidence in the years-long bullying campaign orchestrated by her son… and it was only one of several Deku had filled out.

There was no denying the proof right before her eyes. And there was no denying that Deku was now, finally, in a position to potentially ruin her son's future if he so chose to. Because, before Deku hadn't had much hope of anyone ever looking at his journals of evidence and doing something about them. If nothing else, maybe some small part of him thought he could get away with writing a tell-all autobiography about Kacchan once the other boy became a big damn Pro Hero, as his incredibly powerful quirk seemed to have him on track for.

But all of that had changed in recent works. Deku wasn't Quirkless anymore for one… and more than that, he'd passed the UA Entrance Exam and was about to be in the Pro Hero Class, right alongside Kacchan. For the first time in a long time, they were suddenly peers, and Deku's concerns and more importantly, his evidence of Kacchan's unheroic actions might just be enough to get the other boy thrown out of the course altogether.

"I-Izuku… what… w-what do you want?"

Now, the young man knew that Mitsuki Bakugo had just as great of a temper as her son. She was just better at controlling it, but back when he and Kacchan had still been the best of friends, Deku distinctly remembered a couple of times that the gorgeous older woman had blown her top at them, more specifically at Kacchan. The mother and son had a very loving relationship to be sure, but it could also be quite the fiery one.

Right now though, Mitsuki seemed to be holding in her temper, clutching at her skirt with both hands as she sets the journal down on the table between them, staring at it like it personally betrayed her, but more likely thinking of Kacchan and how much he'd fucked up. Deku though, had no desire to provoke Mitsuki's temper any more than need be. So, he goes with blatant honesty.

"I don't know. I want him to stop, of course. I like to think that will happen on its own though, once I prove myself at UA again and again. I'm not the Quirkless brat he can push around with impunity anymore, and he'll get that fast. Or he won't, and the teachers will smack him down, I suspect."

Deku pauses, cocking his head to the side, staring at Mitsuki for a long moment. Kacchan's mother… had always 'had it going on' as the saying went. The older woman was actually Deku's first crush, really, one that he couldn't say he'd ever even gotten over. Her quirk made it hard to forget her. Glycerin, it was called, and it gave her absolutely perfect skin. Despite being in her thirties, Kacchan's mom was still youthful and all around beautiful, looking as gorgeous as she'd been when Deku had first developed his crush years before.

"But stopping isn't enough. It doesn't make up for what he did to me."

"No… n-no it does not…"

Deku smiles and nods at Mitsuki's murmured words. He's glad that she agrees with her, because it means she might just be able to stomach what he's decided.

"I wanna get back at him, Mrs. Bakugo. But of course, I'm not the kind of boy who starts fights, and I have no intention of endangering my own position at UA. I wanna get back at him… and I figured you could help me do it."

Blinking, Mitsuki looks owlishly confused as she cocks her head to the side.

"I… I can assure you I'll punish him most severely for all of this! I-!"

Deku just cuts her off with a raised hand and a shake of his head.

"No. I mean, let's be honest, you're not a bad mother, Mrs. Bakugo. And yet, Kacchan has grown up spoiled and entitled all the same. Really, how much control do you have over him, at this point?"

Her shoulders slump in defeat, a telling sign that he's right on the money. Sensing a moment of weakness, Deku goes in for the kill, putting the next stage of his plan into motion.

"Do you want to make up for your son's crimes against me, Mrs. Bakugo? If you truly care, then you'll accept my simple request… and pay with your body."

That gets a jolt from the MILF, her red eyes widening as she stares at him, speechless. Deku has laid it all on the table now though, and he's using every single ounce of bravado and gumption he has not to shake or tremble. Sitting up straight, puffing out his chest, he stares right back at her, waiting for the inevitable blow up, waiting for her to kick him out of her home for daring to suggest such a thing.

If she does so, he's not entirely sure what he'll do next. He's still not entirely sure he's willing to go through with his threat towards Kacchan. The other boy has wanted to be a Pro Hero for so long, Deku isn't entirely confident he has it in him to destroy that dream. And yet… and yet, he's seriously done with Kacchan's bullshit. And he needs some sort of recompense before he can move on with his own life as a Pro Hero under the tutelage of All Might himself.

Kacchan was never going to offer any sort of recompense willingly, so that left it up to Deku to take it… by force.

When Mitsuki Bakugo's shoulders slump and she averts her gaze, a flash of triumph rushes through Deku. He knows he has her now.

"F-Fine… what… what do you want me to do to make up for my son's sins?"

A tad dramatic, but then, it was what it was, wasn't it? Licking his lips, Deku reaches out, and with a bit of his new quirk's power, enhances his strength enough to slide the coffee table between them out of the way one handed. He grins when Mitsuki's eyes widen a bit at the sight, her lips opening in a surprised little 'o'.

Splaying his legs apart, Deku leans back on the couch and gestures to the ground right in front of him.

"How about you get down on your knees and show me your breasts. I want you to use your mouth and tits to pleasure me… and then I'll be satisfied."

His words and tone sound heavily stilted and forced, even to his own ears. But if Mitsuki catches how out of his element Deku is right now, she doesn't say anything or try to capitalize on it. In fact, she seems lost in her own thoughts as she moves from her own seat to the floor, kneeling like he told her to and crawling over.

She won't look him in the eye, but even as she averts her gaze, kneeling between his legs, she reaches up and pulls down her top, exposing her gorgeous busty chest, clad in a bra. The bra goes next, and her tits are released, bouncing all over the place for a second before finally coming to a stop. They're perfectly, in Deku's humble opinion. They're everything he always fantasized about. Kacchan's mother was kneeling right in front of him with her tits out. Pinch him, he must be dreaming.

Knowing he wasn't, knowing this was real life and not fantasy, Deku hurries wets his lips with his tongue and gives another order.

"Take… take my cock out."

He sounds utterly breathless with excitement, but once again, Mitsuki doesn't seem to notice, instead doing as she's told. She reaches up and unbuttons and unzips his pants mechanically, before finally pulling his cock out of his boxers. A gasp leaves her lips, and Deku blinks as she goes wide-eyed at the sight of his dick.

"What? What is it? Is something wrong?"

This is the first time Deku has ever had a woman look at his dick before. And… it's also the only dick he's ever seen. So it's not like he has any way of knowing his cock is a total bitch breaker, big and fat and thick like so few are. Gazing at the massive member that so completely eclipse's her husband's own pecker, Mitsuki Bakugo can only stutter out the truth to the young man it belongs to.

"I-It's… it's so b-big…"

A flush of pride rushes through Deku at that, and he finds himself grinning dopily just a tad. Big cocks were good, right? Women loved big cocks…

"Put it… put it between your tits."

Almost as if in a trance, Mitsuki does as she's told. The Grade A MILF has a rack that just won't quit, and even her large mammaries barely wrap around Deku's impressive girth. The young man groans loudly even still, greatly enjoying his first pair of super soft, malleable breasts pushing against his oh so sensitive cock.

Still entranced, his bully's mom lowers her mouth to his cockhead, and takes it between her lips. As she slides her tits up and down his dick, Deku squirms on the couch, grabbing hold of the couch cushions for a moment before giving in to his instincts, which cause him to grab ahold of her hair. Gripping tightly at Mitsuki's wild, untamed ash-blonde hair, Deku hisses and yanks her down his length, forcing her to take the upper half of his dick into her mouth as the rest remains snug between her tits.

"Mmph! Mmmmph!"

"D-Don't stop, Mrs. Bakugo! You feel so good!"

Deku's groan seems to almost pacify the woman, placating her at least as he instinctively thrusts into her warm, wet mouth, sliding between her tits. Drool collects on her chin and saliva drips down between her breasts, all inside of her cleavage, making the passage slicker and slicker as she gags a little on the fat cockhead of his massive schlong.

"Hulghk… Hulghk… Hulghk…"

It's out of this world, the whole experience. Deku lets out another groan as he continues to half-fuck Kacchan's mom's face, pounding into her mouth and the very start of her throat while enjoying the combination titjob-blowjob very, very much. As new to this all as he is, he can't last long, but he does his best anyways. He doesn't want it to end, for one… and he also doesn't want to blow his load too soon.

Especially since, the longer it goes on, the more Mitsuki seems to get into it, the Grade A MILF slurping and sucking at his cock while sliding her drool-coated tits up and down his dick at a faster and faster pace.

But all good things come to an end, and Deku can feel his release threatening to overwhelm him. With a loud groan, he tips right over the edge, barely offering Kacchan's mother any warning as he yanks her head back off of his cock and proceeds to cum all over her face and chest.

"I'm cumming!"

In response, Mitsuki can do nothing but take it, flinching back as she ends up coated in white, hot seed. Deku's load is as big as his dick, more substantial than anything she's ever experienced before, and it leaves her dazed and confused, as well as glazed over with his spunk. In that moment, witnessing her state, Deku… does something perhaps a little questionable.

Taking out his phone, he quickly turns on the camera and takes a picture. Kacchan's mom doesn't even notice he has his phone out until he does so, the sound of the picture being taken pulling her out of her stupor. Finally, a bit of the famous Bakugo anger leaks through as she glares up at him, the effect somewhat ruined by his cum all over her face.

"Izuku Midoriya, what do you think you're doing?!"

Her tone and her anger might have been enough to make him quail in fear back when he was a little kid, but right now, right here? Deku feels like he's on top of the world, and he's not going to let her stop him.

"I'm doing whatever I want. Unless you want me to send my journals to the UA Principal. Or this photo to your husband."

Her anger is quickly replaced with worry and horror as Mitsuki blanches, the MILF taken aback by Deku's sudden aggression.

"Y-You said you'd be satisfied if I used my mouth and tits t-to pleasure you!"

Grinning, Deku pushes Mitsuki back and stands up, tucking his softening cock away for the time being and gathering up his things as she just kneels there, looking thoroughly messed up and bamboozled.

"I am satisfied… for today. See you soon, Mrs. Bakugo~"

And then, before she can gather herself for a reply or offer any sort of counter-offensive, Deku gets the fuck out of there. But he has every intention of following up. He has every intention of coming back for more. Kacchan's mom is going to be his personal fuck buddy for as long as he wants. THAT will be his ultimate revenge on his former friend turned bully.

So long as Mitsuki Bakugo belongs to him, Deku doesn't care what Kacchan does. He'll be the one on top.

-x-X-x-

"P-Please, don't… my husband is napping in the next room over… he could wake up and stumble upon us at any moment. You shouldn't even be here…"

Deku just scoffs at that, barely paying attention to what Mitsuki is saying as he sidles up behind her, practically pinning her to the kitchen counter. His hand is slipped under the waistband of her skirt and past her panties and ass crack, and he's sliding his fingers along her pussy lips from behind. THOSE, in stark contrast to her mouth, are a lot more honest with him.

After all, if she'd been so afraid of being caught, she could have just not answered the door in the first place. It'd been over a month now since Deku had started his subversion of Kacchan's mom. Both him and his former childhood friend had even started at UA at this point. Kacchan was an irritant to say the least, but ultimately, he'd been a lot less of a bother since Deku went ahead and showed the fact that he had a quirk of his own now, and not a half bad one at that.

But just because Kacchan had backed off a bit, didn't mean Deku was done toying with his mom. Using that photo from their first encounter, Deku had gone the distance. He'd effectively blackmailed Mrs. Bakugo into sex, losing his virginity to her in a somewhat embarrassing first time that was better left in the past.

Although, while he had cum faster than he would have liked, his big fat cock had made Mitsuki cum as well at least once beforehand, much to his surprise. In fact, it was her sudden orgasm that had caught him off guard and driven him over the edge.

Ever since, he'd grown bolder and bolder. It was impossible not to. For all that she complained and whined about what he was doing to her, it was obvious Mitsuki liked it. Even now, her pussy is drooling all over his fingers in anticipation. Rock hard himself and ready for action, Deku lets a low growl leave his lips as he slips into position properly behind Mitsuki, pushing her harder against the kitchen counter and causing her to squeak in distress.

"Cut the crap, you and I both know that you want this, bitch."

"What? I-!"

SMACK!

His hand comes down on her ass, causing her to squeak again and cover her mouth with her own hand in an attempt to keep her voice down. Grinning wickedly, perhaps just a little bit corrupted by the power he now has over his bully's mother, Deku wastes no time in hiking up Mitsuki's skirt over her wide hips and fat ass. She's got the perfect hourglass figure to go along with her youthful skin in his humble opinion. Her buttocks is just as big as her tits, and just as fun to grope and squeeze and play with.

As Mitsuki moans into the palm of her hand, Deku kneads her ass cheeks for a few moments through her panties, before yanking those down to her knees, exposing her shapely behind in its entirety and also showing off her glistening, dripping wet pussy lips as well. Pulling his own cock free of its confines is the work of a moment, but Deku doesn't immediately slip it in… not yet.

Instead, he places the cockhead of his apparently massive pecker against Mitsuki's slit and begins to slowly slide it up and down her cunt, rubbing against her clit for good measure. While NOT fucking her, he also reaches around and pulls down her top, yanking up her bra so he can grab her tits for good measure, giving them a good squeeze before pinching and tugging at her nipples.

Moaning and whimpering in equal measure, Mitsuki removes her hand from her mouth just long enough to try to weakly reprimand him.

"I-Izuku, you've become such a b-bad, bad boy…"

Snorting derisively, Deku rolls his eyes.

"If I'm a bad boy, what does that make you? A bad boy's bitch?"

A shudder runs down Mitsuki's spine, and despite the shake of her head that she gives him, he feels it as her pussy responds to his words. Despite trying to deny it, Deku knows by this point that Mitsuki LIKES being insulted like that, at least by him. Maybe it's because it's a fetish of hers, or maybe it's more personal and she feels like she deserves it for letting her son bully him for so many years.

Either way, the MILF gets tighter whenever he calls her a bitch, or a slut, or his own personal fuck toy. Of course, her tightness is wasted right now, what with his cock merely kissing her pussy lips, rather than thrusting away inside of her like they both want. Except, despite knowing she wants to get fucked, Deku has never heard Mitsuki ask for it. Today, he's decided, that's going to change.

Setting his phone up to record, he gives Mitsuki's ass cheeks another hefty squeeze.

"You want my cock, don't you? Your husband's can't compare, can it? Not anymore…"

"D-Don't say things like that, y-young man. Please…"

Grinning, Deku cocks his head to the side, alternating between molesting her tits and ass in equal measure, weakening her further as the conversation continues.

"But it's true. Look how wet you are for me. When was the last time you got this wet for your husband, huh?"

The way she shudders, the way her pussy lips clench and drool all over his cockhead, makes it clear he's right on the money. Leaning in close, Deku goes for the kill.

"Beg me for it. No one will ever know. I've kept all your other secrets, haven't I? Yours and Kacchan's…"

"P-Please don't bring up my son when you're about to fuck me…"

Scoffing, Deku pulls back a little, shrugging his shoulders as he straightens up.

"Who says I'm going to fuck you. Maybe I won't. Maybe I'll leave it at this for now."

That causes Mitsuki to stiffen, and Deku knows he has her. He smirks easily and waits, knowing that she'll break quite soon. Finally, the words come in a whisper.

"… Please…"

Leaning forward again, leaning over her and wrapping his arms around to play with her breasts, Deku hums questioningly.

"Please… what?"

Shivering, but knowing she's too far gone to pull back now, Mitsuki hangs her head and makes her confession as she begs for his cock.

"Please… I need it. I need your cock, Izuku. I need you to fuck me. Please… please fuck me."

He considers making her beg for it louder, but her husband waking up and interrupting them is a very real concern. Besides, holding the phone up, he stops the recording and then plays it back. Both of them listen as her voice, clear as day, repeats the words she just spoke. Mitsuki stiffens, but before she can raise a fuss over him creating even more blackmail to hold over her head, Deku thrusts forward.

Not prepared for it, she's clinging to the counter when he does so, rather than covering her own mouth. In the end, he has to wrap a hand around her head quite hastily, covering her mouth as a loud cry followed by a long wanton moan leaves the orgasming MILF's lips. Meanwhile, her pussy lips down below are gushing as she cums HARD and explosively around his pistoning cock, her legs shaking and her knees knocking together.

Grunting as he fucks her up against the kitchen counter, Deku grins when he feels her hips begin to push backwards into his thrusts. Hesitantly at first, but then with more conviction, more gusto. She wants it… she wants him. And she's finally acknowledging it, finally being honest with herself. Groaning into her ear, Deku hugs Kacchan's mom from behind and proceeds to plow her right there in a powerful standing fuck in the middle of her own kitchen.

She cums around his thrusting bitch breaker of a member time and time again, but Deku has a lot more experience now, and he's not going to tip over the edge because of some rapid fire MILF cunt clenching down hard around his dick. He fucks her right on through her numerous climaxes, eventually even transitioning her down to the floor.

Face down, ass up, Mitsuki Bakugo is fucked right there on the floor of her own kitchen, with Deku mounting her from above, even putting a foot on the back of her head and grinding her face into the floor as he does so. To be fair, the kitchen floor looks to be kept quite clean… but sure enough, given enough time, they make a mess of it, her pussy juices squirting all over the place and forming a puddle beneath her trembling, quivering, jiggling form.

Finally, Deku cums inside of her, filling Mitsuki with a nice, thick load of his seed. He's not thinking much about anything as he pulls out, figuring they're pretty much done for the day. He certainly doesn't want to stretch his welcome and risk waking up her husband. However, before he can even tuck his messy cock away into his pants, Mitsuki whips herself around.

Coming up from the floor, she moves so fast it almost looks like she's going to attack him. But no, what the broken MILF does instead is grab his cock with her hands and shove it between her breasts, giving him a titjob-blowjob clean-up combo reminiscent of their first time together as she swirls her tongue around his dick and wipes him off using her own body.

There's a lot more enthusiasm in her movements now, and as Deku looks down into the red eyes of his bully's mother, he knows he's succeeded. Mitsuki can't hide from what she truly is anymore… his fuck toy, his sex slave, even. She belongs to him now, mind, body, and soul… and they both know it. There's no coming back, not just because of the blackmail, but because he owns her. Because she knows she can't live without him anymore.

As if to prove it, Mitsuki looks up at him, seeming almost hopeful in her broken state.

"Am I… a-am I doing this right, sir?"

Mouth paradoxically dry and watering at the same time, Deku looks down at the gorgeous MILF he's made his bitch… and grins.

All according to plan.
