MHA: Degenerate Izuku - The Incubus System

A/N: The [Dormant Quirk Pill] is meant to be used on Quirkless people, but should I change it so that it unlocks another quirk for a person who swallows it if they already have a quirk? If yes, should there be the usual consequences of 'Reduced Life Span', which can be negated with MC's Longevity Pills anyway?

1. Yes, anyone can swallow it

2. No, keep it for the quirkless

"Fuck. Me." Ikumi repeated in a stern tone, bringing her face closer to Izuku's, "Don't make me repeat myself a third time..." She lowered her gaze to his lips, her face inching closer and closer until Izuku placed his hands on her shoulders and firmly pushed her away from him, keeping his hands on her for stabilisation

"You're going a bit fast, no? We haven't even had dinner together yet" Izuku countered sarcastically, releasing his hold on her after a few seconds, 'Is this enough?' He wondered as he looked at the system message in front of him

[Side Quest: The Self Cockblock]

[Objective: Reject Ikumi Honjo's Advances]

[Rewards: Maturity Pill, +5,000 LP, +5 SP]

[Failure: Leaks of the user being a proclaimed 'Sexual Harasser']

As a male, Izuku did not want to fall victim to being framed as a rapist, or trafficker, or anything in fact, 'It seems she's not done yet' He noted to himself as the quest was yet to be completed even though he's already rejected her.

"Come on~..." Ikumi brushed her shoulders with her hand in mild disgust, taking a few steps towards Izuku as she pressed up against Izuku's body, "Nobody has to know..." She murmured seductively in his ear, raising a finger to her shirt as she pulled it down a little, revealing more of her cleavage. If he actually tried, Izuku was sure he'd be able to see her nipples with how far down they were

'If I get hard, I die... if I get hard, Inko dies... If I get hard, Mitsuki dies... if I get hard-' Izuku closed his eyes momentarily, repeating a mantra to himself to prevent himself from getting hard as hell from Ikumi's provocative actions, 'If I get hard, I'll be framed!' His eyes snapped open, pushing the girl away once more while also lifting up her shirt by pinching it up by her shoulders

"Any lower, and you'll get frostbites... I should get going now-" Izuku began to turn away, needing to go to the Nurse's Office where he would assist Chisato, when he suddenly felt himself falling backwards. Although he could have caught himself and Ikumi with his [Telekinesis], the horny male in him wanted to see where this was going, 'I'm gonna get the biggest blue-balls... until I get home' Fortunately, he's got women to satisfy him at home

"What're you doing?" Izuku questioned, laying on the grassy floor (which he was very thankful for) with his neck craned up a little to prevent the crushing of Umbria. He looked up at Ikumi who licked her brown glossy lips for sex appeal, seating herself on Izuku's abs as she arched her back slightly and began running her hands up his body, "I know you want this..." She whispered with a low groan, winding her hips a little as her hands were now on Izuku's shoulders

"Get off me" Izuku said calmly, grabbing Ikumi's wrists which halted her movements. She shook her head, attempting to fight out of his grip, "Get off me, please?" He asked with a pinch of kindness, 'I swear to God, if this hot and sexy bitch doesn't get off me I'll-'

"Ikumi-Chan?" Suddenly, the voice of Camie entered their ears, causing them to turn their heads to see the girl looking at the odd scene, "And... the new kid?" The pitch of her voice raised slightly in shock of what she was seeing

"Tch!" Kissing her teeth, Ikumi began to get off of Izuku, "Stay away from Camie, or else" She threatened before walking over to the girl with a large smile on her face, "Camie-chan~ I've been waiting for you!" Ikumi voiced cheerfully, wrapping her arm around Camie's while secretly glaring at Izuku who pat the dust off his clothes

"Izuku Midoriya's the name, not 'new kid'" Izuku corrected Camie with a light chuckle, walking over to her with a raised arm, "It's nice to meet ya, properly this time...?" He said with a wink, causing Camie to clear her throat in embarrassment at the memory of Izuku holding her waist

She raised her hand and shook Izuku's, "Camie Utsushimi- Kya!-" Camie jumped as she abruptly began to get pushed by Ikumi, "Yes yes, it's nice for everyone to meet each other, now let's get going or we'll miss our bus, Camie-Chan~" And so, Ikumi fled the scene, forcing Camie to go with her

"Wow, what a bitch, right?" Izuku asked as Umbria made her way out of his shirt, popping her little head from under his chin, "Gyow-Gyow~" She nodded in agreement, some smoke coming out of her nostrils in a cartoon-like manner, "Oh well, at least I gained some nice things from that interaction" Izuku smiled as he looked at the system pop-ups in front of him

[Camie Utsushimi: Loyalty - 0. Love - 3. Lust - 5] [Camie Utsushimi, a 3rd-year student of Kijimi Junior High with many rumours about her, is an unexperienced virgin who's never had an interest in boys, let alone a boyfriend. The user, however, is the first person to catch her eye much to her own surprise. Unfortunately, she has no time to think about getting a boyfriend as she's trying to become a hero while taking care of her little brother at the same time]

[Camie Utsushimi's Sexual Preferences/Kinks: Submissive, Vanilla]

[Camie Utsushimi's Weaknesses: Sensitive Everywhere]

'That's... wow, I was not expecting that' Izuku's eyes widened a little in surprise, expecting Camie to be a little more kinky, 'Vanilla's cute though' He thought with a smile, moving over to Ikumi's 

[Ikumi Honjo: Loyalty - 0. Love - -5. Lust - 10] [Ikumi Honjo, a 3rd-year student at Kijimi Junior High and Camie Utsushimi's best friend, is a girl with a strong hate for males due to her bad past of cheaters and playboys. Although, as much as she hates to admit it, she does deem the user as 'attractive', this only fuels her dislike as she views the user as a 'Playboy' who has bad intentions with her best friend, Camie Utsushimi, who she believes is starting to catch feelings for the user]

[Ikumi Honjo's Sexual Preferences/Kinks: BDSM, Humiliation, Exhibitionism, Cosplay, Roleplay, Blindfolds and Gagging]

[Ikumi Honjo's Weaknesses: Throat/Neck, Ass, Tits, Thighs, Ears, Legs]

"..." Izuku and Umbria looked down, "Hey!" To prevent traumatising the demon-dragon, Izuku quickly covered her eyes and started doing breathing exercises to calm his erection down, "Gyoo!" With a huff, Umbria began to nibble on Izuku's finger which tickled a little. Fortunately, by the time he lowered his finger, his boner went down so it was all god, "Gyow..." Umbria pouted, which Izuku chose to ignore, 'How kinky... I like it' He gave a mental thumbs-up

He then looked over the "Bad past of cheaters and playboys" part. After seeing that, he thought about giving her SOME leeway with how she acts, but, 'Just 'coz you got cheated on once or twice doesn't mean every guy's automatically a piece of shit, dumb bitch' He shook his head, deciding to move on to his actual rewards

[Side Quest: The Self Cockblock - COMPLETE!]

[Objective: Reject Ikumi Honjo's Advances - COMPLETE]

[Rewards: Maturity Pill, +5,000 LP, +5 SP] He claimed the rewards, [SP: 1 -> 6], [LP: 6,646 -> 11,646]  the pill going to his inventory with its description being:

[Maturity Pill - A pill that, when swallowed, causes a person's body to mature into their prime. Caution: Only works on people below the age of 21], "Huhh~..." Izuku nodded slowly in satisfaction, "Not bad~ Not bad at all~" He then looked at his other completed quest

[Secret Quest Complete!]

[Secret Quest: Gotta Complete 'Em All!]

[Objective: Complete 20 Quests!]

[Rewards: +20 SP, +20,000 LP, Longevity Pill (200 Years)] With his rewards claimed, [SP: 6 -> 26], [LP: 11,646 -> 31,646] Izuku decided to open his inventory and count up how many years he now had total with all the [Longevity Pills] in his inventory

4x [Longevity Pills (25 Years)] + 2x [Longevity Pill (100 Years)] + 4x [Longevity Pill (200 Years)] adds up to a grand total of 1,100 Years! As much as he would like to keep saving the pills and not use them, after taking a look at Umbria's 10,000+ years, his greed got the better of him as he consumed two of his [Longevity Pills (200 Years)] which bumped up his longevity/lifespan from 160 to 560

With everything done and dusted, Izuku began to head to where he actually needed to be: The Nurse's Office

.

.

.

*Knock Knock* After knocking a few times to alarm Chisato of his arrival, Izuku slid the door open to see the woman sat at her desk, completely focused on something. So focused, in fact, that she stuck her tongue out from the side of her mouth, 'Cute' The boy thought as he made his way over to her, looking over her shoulder to see what she was so focused on

'...Nevermind, fuck that' Seeing it was a whole bunch of science-y stuff, Izuku instantly turned his head away in disinterest. If there was a subject he both hated and was extremely bad at in both his past and present life, it was science - in particular, Biology and Chemistry. He was fine with physics as it was more on the maths side, which he was good at.

'Well~ That was the case previously, until I got a system that allows me to purchase skills to make me good at a bunch of stuff, including scie-' Looking at the prices, Izuku couldn't help but slump in defeat as each science subject cost 10,000 LP, 'I'm not about to waste all the LP I have right now on science of all things, maybe once I have more I'll purchase it'

A minute passed, and Chisato's concentration did not falter in the slightest. In fact, she seemed to be even more locked in in whatever she was doing. Because of this, Izuku decided to walk around the Nurse's Office and start snooping a little, opening and closing drawers, looking all over the beds, "Ew-" He grimaced after noticing a small white stain on one of the beds, 'Save it for when you're home' He shook his head, appalled, 'Or at least do it into a tissue, so it doesn't get on the damn sheets!'

"HAA~! DONE!" A few minutes later, Chisato cheered celebratorily, her desirable body flopping backwards into her seat as she loudly exhaled in exhaustion, resting her eyes as cocked her head back, sweat dripping down her forehead, "With what?" Her eyes snapped open, the sight of Izuku's face towering over her, looking down at her with a warm smile, coming into view

"KYAA!-" She squealed in fright, not expecting to be jump-scared by one of the students of the school. However, due to her relaxed position, Chisato's chair began to topple over, bringing her down with it towards Izuku. She attempted to catch herself, her heart skipping a beat as her hand barely missed the desk in front of her

*BANG!* 

"Ogghhhh~" Chisato groaned, 'The floor's surprisingly soft, yet hard...' Slowly opening her eyes, revealing their green colour, it came as a surprise to the teacher to see her student directly under her, "Oh! Are you okay?!" She asked concerningly, seemingly forgetting to get up as she grabbed Izuku's face in worry

"All good!" He answered, giving the teacher a thumbs-up, "And you? Sorry for scaring you, I didn't expect it to end up like..." Izuku lowered his gaze, Chisato following his eyes to see him looking directly at her large breasts which almost popped out of her shirt, "This..." He said quietly, unable to avert his eyes due to the perfect breasts in front of him

"Eyes up, I'm your teacher" With puffed cheeks, Chisato reprimanded the boy by flicking his forehead with her middle finger, "Ow!" She winced weakly, blowing her fingernail, "What's your forehead made out of?" She questioned, STILL unmoving from their position

"My head needs to be able to hold my humungous brain, of course it's strong" Izuku responded with a playful smirk, tapping his index finger on the side of his head to emphasis the fact he was talking about his brain

"Right~-" Chisato rolled her eyes, flicking his forehead once again, which she instantly regretted, "Ow!" She cried, taking a look at her finger once more to see the nail bleeding slightly, much to her and Izuku's concerned surprise

Instantly, the two got up from their position, Chisato walking over to the sink where she rinsed the blood with the tap water. Meanwhile, Izuku opened the cupboard with the plasters, and grabbed a few as he was unsure of which one was the right size for the injury, "Here" He handed the plasters over to her, Chisato drying her nail before wrapping a plaster around it

"Thank you, my little apprentice~" Chisato complimented, looking pleased as she raised her hand and began patting Izuku's head, '...' Unsure of how to react, the boy simply let it happen - after all, the woman was beautiful AND older.

"So, what should I do?" Once everything was calm, Izuku, sat beside Chisato at her desk on a low chair next to her taller one, asked sheepishly, wanting to get his 'School Service' over and done with as quick as possible

"I'll show you" Moving a strand of her over her ear, Chisato leant forward, keeping her hand near her ear to prevent the strand from falling in front of her face, "What you need to do is..." She began to give him instructions, but Izuku was barely able to focus on her words. Rather, he was more focused on the two melons dangling right in front of his face

'This... This is gonna be a tough School Service'

.

.

.

"Thanks for the help, apprentice-chan~ See you tomorrow!" Chisato waved at Izuku from her desk, who stood at the door and was about to leave after spending 2 hours in the Nurse's Office, "See you tomorrow, Hasegaw-"

Chisato frowned, "No~ What did I say for you to call me...?" She questioned with a raised brow, her arms crossed underneath her chest

With a fed-up sigh, 'I just wanna go home... any longer, and I might burst' He thought, referring to the little brother which was threatening to burst any second, "See you tomorrow, Chisato" He corrected with a small wave, sliding the door shut behind him as he walked out of the school

After checking his surroundings, Izuku ran into a quiet and dark alleyway where he took out Umbria from inside his shirt and placed her on top of his head before flying home with his [Incubus Wings] and newly-obtained information, 'I forgot to do this the last few times I saw her'

[Chisato Hasegawa: Loyalty - 5. Love - 10. Lust - 50] [Chisato Hasegawa, the School Nurse of Kijimi Junior High, loves the idea of having an 'Apprenticeship', especially one as 'Adorable' as the User. She views the user's age as an unfortunate case - "If only he was older and not my student, I'd love to have a... taste of him". Then again, the taboo of doing something with a student of hers has been tempting her thoughts for a while]

[Chisato Hasegawa's Sexual Preferences/Kinks: S&M, Breast-Play, Anal, Roleplay]

[Chisato Hasegawa's Weaknesses: Breasts, Throat/Neck, Hymen, Armpits] Izuku blinked, 'Armpits... what an interesting(?) weakness. And hymen? Is she a virgin...? Nah, no way!'

Landing at a rooftop near his house, Izuku retracted his wings before making his way down the house and walking the short minute to his place, [MP: 4,870 -> 870/4,900]. Activating his [Incubus Link], Izuku was relieved to see Inko and Mitsuki together in their room (His room became the 'Master Room', where they all stayed. Inko's room remained unchanged, but it was more of a 'Guest Room' now)

He silently entered the house, wanting to surprise them until- *Knock Knock Knock Knock* With a low groan, Izuku turned around and opened the door, "Hello-" As soon as he did, a pair of hands barged their way through and hardly gripped the collar of shirt

"YOU BASTAR-" The pair of hands were revealed to belong to Katsuki Bakugo, who entered Izuku's house with an infuriated look on his twisted face. Thankfully, like a good pet owner, Izuku chose to calm him by strongly slapping his face, *Slap!* The connection was crispy, and it would definitely leave a mark

Katsuki barely remained conscious, stumbling a little before catching himself. This little time, however, allowed Izuku to easily free himself as he calmly looked at the angered Katsuki, "WHA-!" The explosive boy raised his arm and went to swing at Izuku, who casually blocked the attack with his arm, raised his free hand, and proceeded to slap the other side of Katsuki's face which sent him back a few steps, saved by the closed door

"Nice, now you're matching" Izuku mocked with a toothy grin, pointing at his cheeks which only annoyed Katsuki further, who was barely able to prevent himself from going unconscious, his willpower fueling him - There was also the doorknob, which Katsuki held for balance

"You-!" Persistently, Katsuki opened his mouth once more

"Haa..." But Izuku wasn't going to entertain it for much longer. With a tired sigh, Izuku stepped forward and grabbed Katsuki's face, his strong hand over Katsuki's muted mouth, "Mmngh!" He winced weakly as his feet left the ground, having been raised up in the air by Izuku who pinned him up against the wall, slamming his head a little which caused his vision to go blurry

"Look at you, 'Ka-Chan'..." Izuku snickered, "Ohhh, how the might have fallen, ay?" He chuckled manically to himself, causing Katsuki to glare at him, unable to fight back in his weakened state, "Hey now, is that any way to look at your new daddy" He smirked, "Katsuki-chan~"

Wanting to peer into his mind, Izuku activated his [Mind Reading] ability for 3 seconds, which was all~ he~ needed.

'I'll kill you I'll kill you I'll kill you-' He kept on repeating to himself, much to Izuku's entertainment. However, that wasn't the best part

With the last second he had of his [Mind Reading] ability, Izuku heard 'How could that old hag leave her family for this shitty bastard!?' Causing him to cackle devilishly as he took out a pill from his inventory, lowering his hand a little to open up some space for his mouth to forcefully open with his fingers

"I can show you what your mother left her own family for..." With a [Gender Swap Pill] in hand, Izuku opened up Katsuki's mouth and threw it into his mouth, forcing him to swallow it by giving him a smacking or two whenever he tried to spit it out

Like a transformation in a magical girl show, Katsuki's body began to slowly change one-by-one, starting from his legs before going up his body, ending with his hair and face. Replacing Katsuki was a slightly shorter, beautiful girl with sharper and prettier red eyes; smooth and soft skin; and long blonde hair magically tired up into a spiky ponytail. Unfortunately, her body was very underdeveloped due to age... but that wasn't a problem, as Izuku took out the [Maturity Pill] from his inventory and forcefully fed it to the girl once more, slowly transforming her into her prime form, which only made her 10x more attractive, and her ass and breasts much larger and in perfect shape [Images]

"Wh-What did you do to me!?" She squealed in shock, Izuku not yet finished as he looked the girl in the eye and activated his [Incubus Eye]'s Hypnosis ability, "You've always been a girl, all the way from birth... isn't that right, Katsumi Bakugo?", [MP: 270 -> 222/4,900] He cancelled his ability's hypnosis, Katsumi energetically replying

"Of course I have, you bastard, now let-!" Her high-pitched voice was silenced once more by Izuku's hand, who sighed in relief, 'Thank god that worked. It would be weird if she had the body of a girl, but the mind of a guy' He turned back his attention to Katsumi, looking directly into her blood-red eyes before activating the [Incubus Eye]'s ability to maximise her pleasure, as well as her stats which read

[Katsumi Bakugo: Loyalty - -30. Love - -30. Lust - 70] [Katsumi Bakugo, originally Katsuki Bakugo, was previously best friends with the user until she grew an unusually large hatred for the user. She believes that the user is the reason her family split, which only multiplied her hatred. Though, currently, she's starting to feel conflicted due to the position she's in making her extremely horny]

[Katsuki Bakugo's Sexual Preferences/Kinks: Submissive, Gagging, CNC, Humiliation, Praise]

[Katsumi Bakugo's Weaknesses: Nipples, Throat/Neck, Ass, Arms]

He then read a system notification which had popped up after feeding Katsumi the pill,

[Main Quest: Mind Breaker]

[Main Objective: Break the mind of Katsumi Bakugo]

[Bonus Objective: Get Katsumi Bakugo to admit her true feelings without the use of any Active Skills]

[Rewards: To be decided...]

[Bonus Rewards: +20,000 LP, +25 SP, Awakened Explosion Quirk Pill, 2x Random Skills]

[Failure of Bonus Objective: Constant Disobedience of Katsumi Bakugo (Caution: Extremely Annoying)]

-----

A/N: Some may be uncomfortable with the next chapter, so I suggest not reading it if you're uncomfortable with 1. Gender-Bending, 2. Extremely Rough/Revenge Sex, 3. Rape-y Sex/Mind-Breaking Sex.

These reason I made those Katsumi's Kinks is to make it seems as less rape-y as possible to make myself more comfortable writing the next chapter lol (More comfortable with writing a 'CNC' scene than a Rape scene, obviously)

Thanks for Reading

Hope you enjoyed the chapter
