"One would think," a tongue flicks out to trace her clit, "All Might took on his protege for how good she tastes." All for One smiles, face hovering over Izuku's cunt.
"Shut up," she bites out, "shut up."
He trails a hand down her quivering thighs, using his heat-vision quirk to find her core, pressing a thumb there so he can feel the way she parts around his finger, already fucked open by his tongue.
"But look at how prettily you've laid yourself out for me," he answers.
He's right.
Deku's own arms are looped underneath her knees, holding her open for him so she's completely exposed. Silvery grey veins trace their way along her legs and arms—evidence of the parasitic quirk that allows him to control her with a mere thought. As they speak, the veins inch up her shoulders, her hips, creeping towards her core.
"You won't get away with this," Izuku says, then gasps as All for One's fingers curl upwards, rubbing against her just right.
"Oh, but I already am."
Izuku's stomach lurches as her arms and legs move against her will. All for One leans back with a sigh, and she crawls over to him, movements somewhat stiff and jerky. Her arms loop themselves around his neck, an ugly facsimile of a lover's embrace, and her belly clenches as her thighs begin to lower themselves. All for One's arm comes around her waist, pressing her against him until their faces are but an inch apart. His hands pinch at the fat lining her hips as he helps her lower herself onto his cock.
She can't help but gasp a little, lips parting and head dropping back as his cock breaches her, hot and heavy. Deep.
"That's it," All for One whispers, stroking his hand along her lower back, "just like that, baby girl."
The pace he sets for them is punishing. Izuku can feel her muscles burning, even if she can't control them herself. It's fast, frenzied, and she can't help but cry out when he reaches up to tug at her nipples, biting along her collarbone.
"Did All Might ever get a taste of this pussy?" He punctuates his words by squeezing her ass, kneading it and guiding her hips into a filthy grind, so that her clit rubs against him and slick noises fill the room.
"Nngh!" Izuku bites her tongue, willing herself to be quiet.
"I hope he did," All for One continues, conversationally. "You would enjoy that, wouldn't you? Look at how wet you are for me...I'm sure Nana taught him how to treat a woman right. Tell me, whose cock do you like better? Be honest, now."
She continues to bounce on his lap, hands gripping onto All for One's shoulders.
"Hnng...You make me— ah! — sick ," she spits. But she's blushing, the heat in her belly growing and warming her inside out. Her skin prickles under his large hands, which continue to explore her body.
"That's not what your body says," he chuckles.
"You'll never be as great as All Might," Izuku replies, vehemence and righteous anger lacing her tone. "You're just a relic of the past, an overgrown child who's angry the world forgot about him. Even with all of your power, you could never hope to match up to All Mi—"
Her words are cut off with a scream. All for One steadies her as her limbs stretch, fingers and elbows bending back at an impossible angle. The muscles of her quads bunch and knot as her legs snap straight, trembling as the force of her own muscles clenching overrides her body's limitations, putting pressure on all her bones and joints. Her muscles shriek , tearing themselves apart as they try to move in ways her body can't. The silvery veins crawl across her shoulders and chest, up her hips, pulsing with All for One's silent command.
And then she slumps, muscles shaking and burning from the strain.
"I think I have been too kind," All for One says. "My bad. A rookie mistake on my part. I apologize, how unprofessional of me."
He lifts her and drapes her limp, trembling body on the bed, then hovers over her.
She moans as her arms shift again, fingers reaching up to wrap around her own neck. He slips his cock back inside of her with a sigh, and resumes fucking her, one of her knees bent over his shoulder.
Before long her face is turning red, and she begins to choke, fingers squeezing and pressing down on her larynx. Her pussy clenches, and All for One groans. Her face steadily darkens, her eyes begin to glaze over. Her mouth moves soundlessly, the crushing pressure around her windpipe not allowing her to speak.
"Good girl," he whispers, and licks at her collarbone. Her pussy twitches. "That's much better, isn't it? You like it when Daddy fucks you, don't you?"
He has her move her legs so they're wrapped around his waist.
"I'm going to cum inside you. Feed you my seed. Breed you, fuck you until your body remembers nothing but the shape of my cock. Yeah, this is the cunt of a good, obedient bitch, isn't it?"
He leans down to whisper in her ear, brushing messy curls off of her forehead and caressing her puffy face.
"My pretty, little wife. I'll have you bear my children. See if anyone will care about you once you've become my whore. I'll fuck you so stupid you won't be able to remember what it's like to want anything other than this cock."
The virus continues to spread. The quirk-sense in All for One's brain tells him when it's reached her cunt, and he smiles viciously.
"Yeah, you'd like that, wouldn't you, Izuku? C'mon, baby girl. Come for me."
Her hands relax and she lets out a breathless cry as her entire body spasms with the intensity of her forced orgasm.
"Again."
Inexplicably, another wave of burning hot pleasure runs through her, and this time she really does cry out, hoarsely. Her walls spasm, the place where their bodies meet soaked in her juices, accentuating the sound of their fucking.
"I can do this as many times as I want. You cum for me when I want you to. And you'll take my seed whenever I give it to you. You're mine now, Izuku. This cunt is now my property."
Before long she's squirming, over-sensitive and tender from the multiple chain orgasms that All for One forces her through, tears leaking down her face. Her teeth tear through her lips as she bites them to hold back her need to plea , to beg him to stop.
She won't give him the satisfaction.
But she can't hold back the sob when his hips stutter to a stop, a low groan rumbling through his chest as he cums, fucking her through it, pushing his seed as deep inside her as possible.
"You take it so well, Izuku, see? Your body was made for this."
The virus has spread across her chest, up her neck, and past her belly button now.
"F-fuck you."
Suddenly her chest locks up and she gasps, only for her throat to lock up. All for One tenderly squeezes one of her breasts as he rolls the nipple of the other in his mouth, smiling as she seizes beneath him.
After five excruciating seconds, he restarts her heart and she gasps, lungs releasing.
"The best thing about this quirk," he says conversationally, "is the way it overrides both voluntary and involuntary processes. You understand my meaning, don't you?"
The silvery veins creep up her chin and face.
He leans back, lazily stroking his cock back to life, then runs a hand through her hair and has her crawl over him.
"I can even suppress your gag reflex."
She keeps her jaw clenched closed for as long as possible, but slowly control over the bottom half of her face slips away, and eventually All for One is weaving his fingers through her hair and lowering her mouth around his cock. He lazily thrusts up into the warmth, cock slipping in and out without resistance, delighting in the way she drools around him.
"You know, once the virus reaches your brain, I'll be able to control that, too. You'll be my cocksleeve. You won't even remember that you ever wanted to be anything else. You won't remember anything except the need to be bred over, and over, and over again, by me. "
Her eyes widen in panic, and he pulls her off so he can bring her face up to his.
"Did you think I was joking when I said you'd be mine, darling?"
All for One releases control over her face momentarily, just to listen to the way she begins to cry and sob. His cock twitches; he can just imagine the way her expression morphs into one of panic and desperation, the way her eyes must be filled with fear.
"Please," she says. "Please, no. Stop—I'll, I'll do what you want, just, please, don't do this, ple—"
Another orgasm wracks itself through her frame and her eyes roll back as she cries out, entire body quivering. She doesn't even notice that in that moment, All for One had returned her body to her.
The virus is creeping up her cheekbones now.
"Please," she says, again. "I'll do anything."
He lowers her onto her back, and resumes fucking her. It's a slow grind, less fucking and more of him relishing in the feeling of her warmth swallowing him.
"Anything?"
She continues crying.
"Anything."
"Then I want you to keep begging."
The bed starts to creak as his hips pick up their pace. Her hands are lying limp by her head, legs wrapped around his waist again. She's an image straight from a porn magazine, a wet dream. Her pussy oozes with slick, clenching down on him, hard.
"I'm begging you, please—I'll do what you want—anything—just, please, stop, stop it, stop— "
The virus has reached her hairline.
"I don't want this! Please! Please, daddy, please—"
Her face is a mess of snot, a blush riding high on her cheeks as she thrashes her head from side to side, toes curling and hands fisting in the sheets.
"Daddy, daddy please, this isn't what I want, I'll be good, I'll be so good—"
"What do you want, then, darling?"
"I want you to fuck me!" She screams. "Fuck me for real! Harder! Faster! Daddy, daddy please, my pussy is so hungry, so hungry for your cock, I can't take it anymore, fuck me, fuck me, fuckmefuckme fuckme—"
Her orgasm, this one not forced, crashes over her and her jaw drops open in an expression of pure ecstasy as she moans, long and low, back snapping into an impossible arch.
"Good girl," All for One says. "That's it. Just like that."
She sniffles.
"I was good?"
He pats her cheek, feeling for the way her mouth slackens and opens beneath his touch. Though he can't see it, the look in her eyes is vacant, lost.
"You were perfect. This is what you were meant to be. I'll breed you like livestock and make you my perfect, slutty little wife. How does that sound?"
She gives him a dazzlingly sincere smile.
"Thank you, daddy."
"It's no problem, sweetheart. No problem at all."
