Chapter 1: The Incubus System

"Ugh..." In the bathtub of the Midoriya Household lay a groaning young boy with a rounded face framed by a short mop of fluffy dark-green hair turned wet from the water he was soaked in, "Where... am I?" The boy grasped his pained head, weakly opening his large eyes which revealed his irises to be the same colour as his hair

Years of memories flooded into his aching head, joining with those of his past life as Cole Luiz, an 18-year old boy from Europe who had died after edging for hours and finally ejaculating to a doujin of an anime known as 'My Hero Academia' - which was the world he now inhabited in as none other than the main character: Izuku Midoriya

"My head..." Slowly, as the memories reached their end, the banging in his head lightened until they were fully gone, "What an embarrassing death" Izuku silently cried as he imagined his parents entering his room to find him dead, his little brother out in the open for the world to see, 'At least I'm not there to witness it'

With a sigh of relief, he lifted himself up and got out of the bathtub, grabbing his new body's nearby towel to dry himself with, starting by running the towel through his hair once before letting it naturally dry and moving down to the rest of his body

While wiping his back with a calm expression, Izuku's body jolted and his eyebrows lifted themselves up in shock at the sudden holographic words that had appeared in front him that read:

"[...User has been bounded with The Incubus System, congratulations!]?" He read, a sceptical look on his face, 'Reincarnating as the Main Character, and then receiving a System as my Golden Finger... this sounds too good to be true' He thought cautiously, new words appearing in the process

[The Incubus System requires the user to commit sexual acts to maximise your potential]

[There are 5 Main Functions of The Incubus System: Status, Skills, Quests, Shop, and Inventory] [Would you like a brief description of each function? Y/N] With a thought, Izuku accepted the offer of their descriptions

[Status - Reveals to the user his status which shows his information and stats]

[Skills - Shows the user all the skills he owns]

[Quests - Shows the list the user gains from the system, earning rewards by completing them]

[Shop - A shop with LP as its currency, where the user is able to purchase a variety of items, skills, and more]

[Inventory - An infinite space in the system which holds item's placed in there by the user]

[To finish the tutorial of the system, open the user's 'Status' and then open the 'Inventory' once the user is done reading through all his information]

Based off his knowledge of fictional works in his past life, Izuku figured that to open his Status, he simply had to think of the word 'Status' and, as expected, it had opened

[Race: Human]

[MP: 100/100]

[Strength: 2]

[Dexterity: 3]

[Vitality: 4]

[Intelligence: 10]

[Charm: 4]

[SP: 0]

[LP: 0]

--

He then focused on each section, hoping for more information similar to the descriptions of the System's functions. Fortunately, it worked which put a smile on Izuku's face. Name, Age, Race, Level/Exp, HP, and MP were self explanatory

[Strength - Strength and Durability]

[Dexterity - Agility, Reflexes, etc]

[Vitality - Stamina and Health]

[Intelligence - Smartness, Mana, Memory, etc]

[Charm - Looks, Height, Charisma]

[SP - Stat Points, used to increase stats]

[LP - Lust Points, used in the shop and other places in the system]

Looking at this body's starts, Izuku was rather disappointed to say the least, 'Seriously, why didn't this guy at least go gym or something after finding out he was quirkless - whether he was bullied or not, that doesn't give him an excuse to be lazy' He complained internally, disliking that part of Izuku Midoriya

"Though, I must say..." He mumbled to himself, bringing his hand up to his face as he rubbed his chin in thought and rubbed his imaginary long, white beard, "This system kinda suits me" He chuckled lightly at his statement, reminiscing all of the doujins he read in his past life before sighing, "Haaa... I'm such a horny bastard" He admitted, as much as he didn't want to

Having looked at his status, Izuku then thought about opening his 'Inventory' which had many rows and columns of blank boxes, except for the first box which had a wrapped present as its icon, [The tutorial has ended, have a gift to start off your lustful journey! Good luck!]

'This system seems rather jolly... very suspicious' He was cautious, but he also wasn't one to complain as he excitedly summoned the mystery box out of his inventory, looking at the gift in his hands like a little boy waiting impatiently to open his Christmas gifts.

[Open 'Mystery Box'? Y/N] He opened it, the box floating out of his hands and stopping in the air in front of him, shaking for a few seconds before a loud *Pop!* sounded, illusionary confetti coming out of the box, 5 icons rising from there.

The first icon resembled a pink potion; the second, '10,000'; the third, '20'; the fourth, an ancient book with a question mark on it; and last but not least, another box with a question mark on it, [Claim Rewards? Y/N]

Claiming the rewards, the first 3 boxes of the inventory was replaced with the potion and two mysterious items, [User has gained 10,000LP!] [User has gained 20SP!] were two of his five rewards

Focusing his mind on the potion, he summoned it out of his inventory and it appeared in his hand, a pink liquid swirling around in the glass bottle that read [Race Changing Potion: A potion which changes the drinker's race to Incubus]

"Woah..." Raising the glass up high, he began twirling the bottle as he watched the liquid that looked surprisingly delicious move around. Suddenly, as he went to open up the bottle and drink the liquid inside it, a woman's nearby shout could be heard

"Izuku, are you okay!?" Izuku recognised the owner of the voice as this body's mother, "You've been in there for a long time!" She sounded concerned, considering the fact Izuku was in there for over an hour. Judging by the volume and clearness of her words, she was right outside the door of the bathroom

Throwing the potion back in the inventory to be safe, Izuku replied while going back to drying himself, "I'm alright, Kaa-san! Just drying myself off now!" The boy cringed at his acting, attempting to resemble and act how the original Izuku would

(A/N: Should I use japanese honorifics like 'Kaa-san', or just stick to 'Mom' and others)

With a sigh of relief, Inko spoke loudly in a gentle tone, "That's good... don't be too long, dinner's going to be finished in a few minutes, okay!?" She informed him, Izuku smiling as he would kill for some food right now, if his rumbling stomach didn't give away how hungry he was already

"Okay! I'm nearly finished!" Izuku shouted back, rushing to dry himself off, eyeing his fresh PJs hung on the door knob of the bathroom.

Once he was done with drying himself off, he put putting his clothes on aside as he re-opened his inventory and took out the [Race Changing Potion]. Taking off the cork, Izuku brought the opened glass bottle up to his nose and gave it a quick sniff, "Smells... good, surprisingly"

The face that it smelled good made it easier for him to drink it, which he did, his body getting hot as if a heated stove was swallowed by him, "A-Agh..." He clutched his stomach, running to sit on the toilet seat as the feeling in his stomach was like he was about to have the worst diarrhoea of both his lives.

His body began to crack and ache, the pain launching him off his seat as he swiftly grabbed a dry towel and threw it in his mouth to muffle his screams.

Minutes which felt like hours passed, and the pain and hot feeling had finally subsided. Getting up with a bit of struggle, Izuku widened his eyes as he noticed he was currently looking at a higher tile on the bathroom wall than a few minutes ago, "I've... gotten taller" He gasped, jogging over to the sink which had a mirror which allowed him to see his sexy reflection

"Goddamn, I'm hot!" He exclaimed narcissistically, but it would be difficult for someone to disagree with him. Replacing Izuku's previous looks was a taller boy with a face more handsome and cute than before. His fluffy hair had grown longer and more straight, part of his green hair getting lighter. On his freshly sculpted face, a diamond mark formed on his forehead, and his green eyes became much more dazzling and beautiful, red markings around his eye. He was the splitting image of Xiao from Genshin Impact, except more child-like and with charming green eyes rather than Xiao's yellow/orange eyes [Images]

Izuku was previously 5ft2 (157cm), but currently he was around 5ft4 possibly 5ft5 (Around 162-165cm), so a few inches which made a good difference as 2/3 inches was quite big, 'Very big' He nodded

He then looked down, "Wow!" He almost jumped back in shock at the python in between his legs, 'And it's not even hard, it's soft!' With this new change, all that was left to do is check his 'Status' as there was definitely a change

[Name: Izuku Midoriya]

[Age: 13] 

[Race: Human -> Incubus]

[Level: 1] (Exp: 0/100%)

[HP: 100/100 -> 750/750]

[MP: 100/100 -> 750/750]

[Strength: 2 -> 12]

[Intelligence: 10 -> 25]

[Charm: 4 -> 24]

[SP: 0 -> 20]

[LP: 0 -> 10,000]

[New skills have been gained!] The system notified him, so he opened his 'Skills' tab next after smirking at his new and good improvement

[Indomitable Willpower (Passive) - The user has an unnaturally strong will which enables them to endure great physical pain and psychological trauma, possessing an extreme amount of perseverance and will refuse to surrender no matter how many difficulties they may face through sheer will.

[Golden Fingers Lv. MAX (Active) - Grants the user, when activated, godly fingers that bring maximum pleasure from the slightest touch by the user]

Though he had to admit the skills were pretty good, he wondered, "Why the hell are there essays for descriptions?"

Curious to find out more of his change, he was saddened to hear Inko calling out to him, "DINNER'S READY!"

With a kiss of his teeth, Izuku put on his PJs, but he took off his shirt as it was too tight on his grown body, and he ignored the clear tent on his pants threatening to burst as he carefully tucked it down his leg. Walking down the stairs shirtless, his eyes bulged in sudden realisation, 'Shit! How am I gonna explain this?' Thinking on the spot, he opening up the system's 'Shop'

[Search...]

[Items]

[Skills]

[Pills]

Pressing on the Search option, he searched for an '[Acting]' skill which he typed into the bar, an option for an [Acting] skill popping up

[Acting Lv. 1 (Active) - When activated, the user's acting improves which makes his words and actions much more convincing the higher the level] [Cost: 1,000 LP]

Unsure if 1,000 LP was expensive, he brought the skill anyway [Acting Lv. 1 Purchased! -1,000 LP] and walked into the kitchen to see Inko's back to him as she finished preparing her and Izuku's plates of food, his eyes glancing down to her buttocks as he lowered himself onto his seat.

'Damn... what a nice ass!' He licked his lips lustfully, her ass much more plump and juicy as a result of the chub Inko gained over the years as a result of her depression of her thinking of herself as a failure of a mother due to Izuku coming out as quirkless, feeling as if she was the reason his dreams of having a strong quirk like his neighbour and friend Katsuki Bakugo being shattered.

Though she was more chubbier than her skinny self years ago, she was much less big-boned than her canon appearance. Her face had a bit of fat, which simply made her look malnourished, and all the food she ate had appeared to gone down to her ass. Although he was unable to see it currently, Izuku knew it had equally gone to her breasts as well.

Images of him approaching Inko from behind and taking off her apron and clothes excited him, a little too much as his snake grew little by little and was on the verge of ripping his pants in two, 'Jesus... I wanna fuck her so bad' The fact he was this body's mother didn't matter to him. After all, his mindset was 'She's Izuku Midoriya's mother, not Cole Luiz's'

[A new mission has been given!] Taking his eyes off of Inko, he looked at the system notification and opened it

[Main Quest: Mother-Fucker! Part 1]

[Type: Chain]

[Objective: Have sex with Inko Midoriya]

[Rewards: Random Skill, 2 Levels, +15 SP, +5,000 LP, and 2nd part of the chain quest]

[P.S. As this is the user's first quest, rewards have been slightly boosted]

"And~ Done!" Having finished setting up the plates, Inko picked them up and turned around, noticing Izuku's drastic change almost instantly, "I... Izuku?"

Looking down at the table, a smirk appeared on Izuku's charming face as he activated his [Acting] skill, "Yes, Kaa-san?" Lifting his head with a slight tilt to the side, Izuku gave Inko a warm and soothing smile

'May Act 1... begin!'
