1-B Arc starts today.
Also, I'm getting busier, unfortunately, that means I'll probably have to cut down from the usual 2100-2500 words to somewhere in between 1K-2K words
Izuku loved I-Island. The weather, the inventions, the heroes - And especially the women. And the women of I-Island loved Izuku. It was unfortunate for Melissa that unless she had him fly directly to where she was, there was going to be one group or another of I-Island inhabitants who were busy adding to its population.
But at the moment, Izuku was settling into his hotel room. Melissa liked to make the booty calls an event, had him being picked up, they would go out for a nice dinner, do something to enjoy on I-Island which was mostly checking out some cool new machine, then back to her lab to fuck her so hard she needed one of the various power suits to even walk for a while.
That said, it took time, which is why Izuku was having some R in his hotel room, starting with tossing his backpack aside, then just as casually tossing his carry on bag on the bed and unzipping it - Revealing the pint-size girl of his sister class, Kimori Kinoko in her mushroom-themed hero costume.
She panted heavily as she was let out for fresh air, the achy twitches in her limbs letting him know just how cramped and uncomfortable she was for the many hours of travel from stuffing her in there to actually getting here.
Before she could speak, he grabbed her by the top of her long, brown hair and pulled her down onto all fours. His rough, scarred hand was so large compared to her that he could probably fit her entire head between both of them, and she was so light that he could have pushed her around with a finger or two - But overwhelming her with the casual display was too good to pass on.
Then, he grabbed her from under her stomach like a medium-sized dog and picked her up, and without a moment longer of hesitation forced his cock down her throat, making her tight throat squeeze his cock and spasm while she gagged and choked.
"Don't sound so ungrateful, I know you must've been starving." He taunted. His grip on her became firm, and he started moving her back and forth on his cock like an onahole, just a tiny, fragile, weightless thing to jerk off with.
His cock pushed further than the back of her throat, clogging her airways so she couldn't even breathe through her nose as it abused her gag reflex, making her entire body convulse and squirm on his dick - Probably putting her consciousness in danger, but giving him a better squeeze, so it was something he was willing to risk, and pulling out left just as huge of a vaccuum inside her, letting her get out maybe a half or full breath before he dragged her body down again, burying his cock down into her body.
With how much Izuku's cock bullied her insides and forced it to compensate to take all of it, Izuku thought of her body more like a literal cocksleeve than anything. And believe him when he said she didn't do anything to deter that way of thinking - Case in point being how readily she allowed herself to get pushed into his traveling bag.
He decided to sit back on the bed, now bringing her up and down like a dumbbell on his dick, forcing her face-down to bob on it constantly while her ass was in the air and her limbs hung with no practical use in the situation she was stuck in.
Now, with Kimori acting as his cocksleeve, he started looking on his phone and scrolling through his messages. So many girls he was leaving high and dry for this trip, and they were already sending him "I miss you!" and "Come home soon!" Messages that ranged from subtle longing to unprompted nudes - Ochako even took it a step further and just sent a video of her masturbating while moaning his name.
Even Melissa took a picture of how she was going to look in tonight's lingerie after he pulled the dress off her, and he started pumping her on his dick faster in excitement. Then, he smirked as he got an idea and texted her that she was coming home with him for a threesome with Mei, just for the novelty of screwing his two support sluts at once.
Kimori's throat was strained and forced to take his cock without a hint of respite or mercy, only being able to get maybe a full breath every two thrusts, burning her chest as she struggled to keep herself awake - Although, if she was really so attached to being awake while being used, she would've been tapping out or focused on breathing, or even stop sucking him off instead, but did none of those things.
She went without panties, so her wet, hot pussy dripped her juices onto the ground while some of it just slid down her stomach, staining her hero costume and would likely ruin it if he kept her up here for long. Then again, she had that slutty parody version of her costume Izuku got her, so even if it was ruined, she wouldn't doubt Izuku would make Mei put the maintance\upgrades of her costume to the back of her To-do list just to have her prancing around in that slutty get-up for a while.
After a few moments she noticed Izuku was looking at her again and tossed his phone aside. With his now free hand, he reached over her and between her spread, dangling legs to toy with her pussy. It was less of fingering her to get her off, and more like spreading her pussy a bit and feeling her out, each small movement making her body shudder and twitch again, giving him more incitive to touch her to hear her gagged moans and feel her tremble.
"There we go. Nice and ready like a good cocksleeve." He said, before using both hands to finally pull her up and off his cock with a wet, lewd-sounding 'Pop!~'
He stood up and held his arms straight out, holding her like a doll and not even allowing her legs to touch the ground as she heaved and panted - More like a helpless fish out of water that couldn't move of her own accord than a person, much less a heroine in training.
"Hm… Oh right, I forgot to feed you. How about it? Would you rather eat, or-"
"Sex!" She answered instantly, having to close her mouth and suck in her drool. "Sex, s-sex right shrooming now, please!"
"Of course. I shouldn't have asked." Izuku said with a smirk. "Hey, make me two nice, big mushrooms with dense stalks."
Curiously, she spawned two mushrooms fitting the description of his demand and finched as he tore them from her palm. Then, he stuffed one in her mouth sideways, and after nibbling it, she realized it would probably take hours for her poor jaw to break through it - But more like days, considering how sore her jaw would get. It was almost like a steel bar.
"There. Since I know the only things coming out of your cocksleeve mouth is gonna be you begging for it harder. Don't worry, I'll have that front covered." He assured with a wink, making her blush even harder as he spun her around, making her face the wall while her ass was presented to him.
He had her bent over his thick, muscular arm like a towel, and she whimpered as she tried looking back - But got all the answers she needed when he pressed the butt of the stalk into her ass, steadily pushing it in as she bit on the stalk harder and squealed with pleasure, her pussy gushing and making her juices flow down her thigh.
Each little shove was delivered with sadistic glee, loving how she squirmed and kicked slightly as he forced her mushroom in her ass until the cap was pressing against her ass and potruding out like a rabbit tail. Satisfied, he gave her a quick spank to make her squeal with delight into her makeshift mushroom gag.
He grabbed her by both sides again and lowered her just enough to get his cock to press against her cunt, with her feet still a few inches off the ground as he started to press his own 'mushroom' to fill her last hole.
Izuku let out a small, relieved-sounding sigh as he pushed into her cunt, feeling her warm, hot pussy squeeze around his dick. She was too small to handle something as big as he was, but neither of them cared - It actually made it better, since Izuku got to enjoy an extra small, extra tight fucksleeve, and Kinoko got to enjoy being ravaged by a man in a way most other women could only dream of.
When he hilted inside her he could feel how much she strained to take him, each heartbeat vibrating her body around his cock as her organs were forced to shift around the presence of his cock. "I'll never get tired of you. You're way too tight and convenient to use, Kinoko." He said, bascially giving her lifelong tenure into his harem as he started to thrust while moving her body back and forth, treating her like a cocksleeve again.
The sound of rhythmic claps and smacking quickly drowned out the sound of her muffled moaning with his powerful hips smacking her ass, making the jiggling meat of her butt wobble and clap each time it came back.
"I'm lucky there's such quality meat in the hero course alone. Or at least, that's what I would say. But it's more like you're all lucky I'm here with you." He said as he started bouncing her harder, burying his cock into her undersized pussy with even greater force as she mewled and screamed with pleasure.
He spanked her again, covering most of her ass with a harsh red handprint as she yelped with pleasure and her back arched. She couldn't stop herself from quivering, from cumming, squealing, curling her toes - She couldn't stop herself from doing anything that Izuku wanted her to do.
If he wanted her to beg, she would, just like how she'd spread her legs, put on any uniform he said, take any position, use any toy, and complete any deprave task he told her to - Because while Kinoko was never the spiritual type, she was easily convinced Izuku was her soulmate: The most perfect, wonderful man to walk the Earth, and she was meant to be at his side forever. Except, if she were being honest, it was more like she was his soul bitch. He was the perfect master, and she was a useful servant meant to be under his heel.
All the evidence she needed was how incredible it felt when he slammed into her over and over again, hitting every sweet spot she had by hitting every spot she had, manhandling her tiny body, filling her nose with his perfect musk, making her swoon on command - She was a helpless Izuku-addict, through and through.
And she was certain her way of thinking wasn't at all being affected by the 'shrooms he was forcing her to knaw on, filling her mouth with the taste of her quickly produced toadstool.
Either way, it didn't matter. Being a perverted onahole and Izuku's sex slave felt too good to ever question, living to have sex over and over again, being conquered by his strength and and virility was so right that there was no other way to live!
She came again, and again soon after, her mind barely processing words or any concept more complicated than pleasure, letting Izuku do as he pleased with her body like she was his property, cumming like a pig for a period of time completely unknown to her until Izuku's pace suddenly hiked, and within moments he slammed her down onto his hips and began to cum, filling Kinoko's insides like she was a condom, making her stomach swell as if she were pregnant in nearly an instant before another pump came. And another, and another, and another.
Finally, Izuku sighed with relief again as he pulled Kinoko off and held her up by the hair instead of under her arms like a doll, letting her hang limply as she groaned with pleasure and pain, so out of it that the mushroom in her mouth could has easily fell out of her slacked jaw.
After a moment of looking her over, he leisurely tossed her across the bed like a towel and grabbed his phone. "Ah, look at the time… Alright, try to make yourself halfway decent when I get back. Melissa and I will need a decent towel for tonight."
And with that, he fixed himself and left Kinoko, drooling, plugged up, and twitching as the aftershocks of cumming so many times wracked her body and mind in equally destructive measure.
If you asked her, it was absolutely Shroomtastic.
