Author's Note: This is shamefully and shamelessly ripped off from Boku to Nottori Villain Nakademia over on nhentai.
I was literally sitting in my room, watching some Senza on YouTube, when the idea to rip off and plagiarise a popular piece of work came to me, while also adding my own spin to it to flesh it out and jazz like that.
If I get enough pushback from you guys I'll take it down, don't worry, I'm not a complete asshole.
Midoriya Izuku (Deku), Yaoyorozu Momo (Creati), and Uraraka Ochaco (Uravity) were patrolling the city in their hero costumes, chatting happily while also being vigilant. Midoriya was in the center of the walk, with a girl on each side of him. It was a slow day, to be honest, with not much happening.
"No, Episodes IV to VI are the best!" Uraraka argued animatedly, making chopping motions like their dear class president.
"I'm not saying they're aren't! I'm just saying I to III have their good moments, such as the light saber fights you don't get to see in the golden trilogy," Izuku countered.
"Aren't we supposed to be, you know, patrolling?" Yaomomo asked with a good natured sigh, a fond smile on her face at having friends.
What a novelty, right?
"We are! Right, Deku?!" Ochaco nudged her crush on his arm.
"We are, but there's not much—"
"Somebody! Please help!" a male voice cried out from a nearby alleyway.
"You were saying?" Yaoyorozu deadpanned before she and Uraraka rushed in, leaving Midoriya behind before he figuratively kicked himself and went in after them. The inside of the alleyway was a big outer area filled with trash cans and a weird purple spill on the ground nearby his two classmates. They, rightfully, were confused when they saw no one calling for help. Scratching their heads, Uraraka and Yaoyorozu were going to say something, anything, before the purple spill morphed itself into a humanoid shape and enwrapped the two with it's slime. The humanoid slime was roughly over six feet tall and didn't have a face, only a black circle that kind of resembled a fingerprint. "Ah! Midoriya, help!"
"Ha ha ha!" the slime, which was of course a villain, laughed, suspending the two heroes in training in the air with its slime. It was covering them all over, molesting their sensitive areas as it trapped them.
"Eww, gross! Deku, I'm sorry!" Uravity apologized as she tried clawing off the villain that was holding her up by the throat.
"I was too careless…" Creati forlornly stated as she thrashed against her restraints.
"Who are you?! And let go of my friends, villain!" Deku questioned and demanded, getting into a fighting stance, brave despite the circumstances.
"Why should I tell you, of all people?" the villain questioned, never ceasing his sexual assault on his friends. "Hmm, these bodies will do nicely."
"I don't know much about his quirk, but maybe it can make itself elastic? Or harden…? I have to help them escape…" Midoriya thought within his racing mind.
"Deku! Don't worry about us, just fight!" Uraraka encouraged, straining against her slimy restraints.
"Yeah, beat his butt, Midoriya!" Momo seconded, biting down on the foul-tasting slime to no avail, it not working.
"What, so you have that kind of relationship?" the slime villain questioned and, if he had a face, smiled cruelly. "Fine, that gives me an idea," he ominously told them as his slime began crawling through the females' ears. "That'll be the perfect hiding place."
Without being able to help, Izuku watched helplessly as his friends got violated in, strangely enough, their ears. Their faces turned began blushing and their saliva production began to ramp up, drooling heavily.
"What is this?! It's inside my head!" Uraraka yelped out, the liquid pouring in by the handful through both ears.
"Something's pushing inside…!" Yaoyorozu yelled, in the same boat as her friend.
Something inside of Midoriya, to this day he didn't know what, told him to just watch, to not try something, anything. He watched as his friends got…well, he didn't know what at the time.
"My head…going blank…" his crush weakly told him, struggling less and less the more purple slime entered her ears.
"My memories…over-written…" Momo just as weakly got out, the both of them going slack in the villain's grasp after most of the body was gone. They were lowered to the ground onto their feet as the last of the slime that composed the villain was gone, slithering away inside of his friends' ears. They stood there, uncomprehendingly, before they seemingly rebooted, blinking away the fuzziness.
The first thing Uraraka did when she had all her faculties was grasp her D-Cup tits, manhandling them and massaging them with eagerness. "Oh! This body is so soft! Oops, I should probably speak like her!" she remarked as she continued to play with her boobs.
"What is happening?" was the first thought that came through Midoriya's mind.
"So you're called Momo!" Yaoyorozu told herself (or was it to Ochaco?), grabbing fistfuls of her ample ass. "A good girl that loves her parents~"
"This one too loves her parents! Ochaco is so sensitive!"
"And this one's quirk will be really useful."
"Could this be…?! They were taken over?!" Izuku realized with dawning horror.
"For a couple of heroes, these bodies are so indecent!" Uraraka playfully began playing with Yaoyorozu's tits, exposing the hardened nipples and areola.
"Jeez, you're embarrassing me!" the vice president moaned out, a smile on both their faces.
For a hormonal teenage to see two of his sexy classmates acting so wantonly, it should've been a dream come true (especially for Mineta)…
But it wasn't.
"R…Release both of them!" Midoriya ordered, an unsure look on his face. Immediately "Yaoyorozu" and "Uraraka" looked deadly serious as they stopped playing with each other, their mouths in a straight line as they assessed him. They looked to each other, silently communicating.
"Of course!" the possessed Uraraka exclaimed, sending out her hands to her side, palms facing the male hero student. "I will release them as soon as I'm done enjoying their bodies!" she clarified.
"What?! You can't do that!"
"Yes I can!" she giggled cruelly. "And of course, I'm counting on you to keep quiet about this…" The villain using Uraraka then smiled evilly, her face contorting in ways that Midoriya couldn't even fathom as she then said, "Because if you don't I might even commit suicide~"
Izuku's eyes widened as his stomach curled in on itself. Uraraka, his crush and longtime friend, killing herself? It was unimaginable, unthinkable.
"I could make so many things to harm myself and others with Yaomomo's quirk, it's not even funny!" Yaoyorozu joined in as she chuckled, squishing her breasts against his left arm. It felt so nice and soft, soft enough that if a pillow was made out of it it'd surely go out of stock.
The weight of their words weighed heavily on his mind as they let the silence stretch on.
"Just kidding! I believe in you, Deku. I just like having sex, killing isn't really my forte," Uraraka clarified as she then too squished her breasts against his right arm. The two of them then began dragging him out of the alleyway, into the light and hustle and bustle of the pedestrians.
"There was no villain, it was a completely uneventful patrol, right, Midoriya?" Yaoyorozu asked him, but her tone was completely unaligned with what she was saying. No, the tone she used was a "telling" one, as if ordering him.
"Yeah, what Yaomomo said! There was no villain, it was all completely uneventful, Deku," Uraraka reinforced, nuzzling into his arm.
"Calm down, Izuku, calm down. There's still a chance…if I can tell a teacher," he thought to himself, blushing hard at the close proximity of his two friends.
"Can anyone tell me the answer for number 43?" their teacher, Aizawa Shouta (Eraserhead), asked at the front of the classroom, holding a book in his right hand. It was the next day, and frustratingly enough the villain was playing his part as a spy damn-near perfectly. The pro hero looked around the room and chose a student, "Uraraka, go for it."
"Yes, the answer is that under duress a civilian is allowed to use their quirk if forced to by a villain!" the girl enthusiastically replied, raising a hand cutely at her desk.
Midoriya clenched up his hands under his desk as he heard his "friend" say that.
"Perfect, good job. For number 44—"
"It's letter B, sir! 'Vigilante use is only applied to those who unlawfully use their quirk,' Aizawa-sensei!" Yaoyorozu butted in, raising a pencil from her desk. "Does that mean quirkless vigilantes aren't a thing?"
"Yaoyorozu, while I appreciate your participation please wait until I call on you. And to answer your question, legally there are no quirkless vigilantes, as that'd be, legally, an oxymoron."
Midoriya wanted to hurl, hearing/seeing his friends act so convincingly.
The bell for the end of the day rung and Aizawa-sensei closed his book, "All right, everyone. School's over, get some rest and make sure I don't see you anytime soon," he drawled out, going to his desk to sort something out.
"Aizawa-sensei, I need to speak to you about—"
"Deku! I need your help with something," Uraraka interrupted him, grabbing his right hand while having a cute expression on her face.
"Me too, Midoriya. Bye Iida, bye everyone!" Yaoyorozu joined in, taking his left hand. She and Ochaco then lead him right out the door, leaving behind their backpacks. They dragged him through the halls, an angry look on their faces as they threw him into an oversized broom closet. "Are you trying to kill these two girls, Midoriya?!" Yaomomo questioned hotly, closing the door loudly behind her and Uraraka.
"Yeah, what Yaomomo said! What gives?" Uravity asked, much calmer than the other girl, somehow, even though they were the same person. Idly Midoriya wondered if he spilt his consciousness when he took over his friends.
"What gives? What gives?! You've taken over my friends and you want me to act normal?! What the hell—"
Yaoyorozu materialized a bowie knife with her hand and held it against her neck, drawing bright crimson blood.
"Lower your voice, Deku, or Yaomomo here is going to have an 'accident,'" Uraraka airquoted. "Is it too much to pretend things are normal, Deku?" she asked, swiping away a cobweb nearby her. "Maybe you need incentive? Yaomomo, what do you think?"
"He hasn't been a very good boy," the vice prez pointed out, withdrawing the knife and letting it clatter to the ground. "But I think if we positively reinforce him then things will go smoother."
"You wanna do it or should I?"
"Eh, you do it."
"Okay!" Uraraka loudly-whispered as she began to fish out her crush's cock.
"Eep!" He was startled, surprised at what was happening.
"Keep it down, Deku, it's just a handjob," Ochaco told him, finally taking out his cock which was massive, even in an unaroused state. "Jeez, I've totally scored a hunk. Do you see this man meat, Yaomomo?" she asked as she began to pump him rhythmically, seeing his dick get even more impressive, the tip all red and engorged with blood.
"I do and I'm so jelly, Uraraka!" Yaoyorozu agreed, her mouth literally salivating at his penis.
Midoriya began to moan at the heavenly feeling that was tending to his cock. The fingers were silky soft and had extra texture from the pads at the end of her fingertips for her quirk. His precum was coming down in droves and lathering her hands with the sticky substance, providing lube. He didn't last longer than two minutes before he felt his orgasm approaching, "I'm gonna cum!"
"Sssh!" they both whispered to him.
"Sorry! I mean, I'm gonna cum," he whispered. Midoriya came soon after all over his crush's hand, covering it with his creamy white seed.
"Jeez, you cum a lot. I like that in a man," Ochaco sinfully whispered as she licked the remnants of his cum off her fingers, offering some to Yaoyorozu, who gratefully licked it off her hand.
The scene was utterly erotic and made his cock stand tall and proud.
"No no, Deku! You don't get another freebie," Uraraka tutted as she put the underwear and pants back over his erection, which was uncomfortable for Izuku. "Actually, I have a better idea," she grinned evilly as purple slime began to come out of Uraraka's head and raced quickly to Midoriya. He was unable to stop or move at all to avoid it as it entered his ears, but only a little. Izuku felt something slot inside his head, a foreign entity presenting itself.
"The hell did you do to me?" Midoriya questioned, clutching his head as he felt all wrong.
"My transformation-type quirk, Possession, only works on women, but since I can't possess you, I'll just monitor you instead, keep your mouth shut," the villain possessing Uraraka explained. "If you so much as try to tell anyone about me, that little piece of me will start squirming inside your head, and I don't need to tell you what will happen," the brown-haired girl warned. Yaoyorozu left the room with a smile on her face, with Uraraka about to leave. "Be a good boy, Deku, and stay quiet, okay?"
He was left alone in the closet, wondering what the fuck even happened. Midoriya shook his head, about to text his heroics teacher about what was happening when, before he could even think about doing that, he was given a migraine from hell that made him fall to the floor in pain. He clutched his head in pain, it feeling never-ending, before it stopped.
A warning, Izuku imagined; a taste of what disobedience will bring.
He was truly and utterly fucked, wasn't he?
