My Hormonal Control Quirk

His REM sleep was always filled with strange and lively dreams, induced by his brain activity thanks to a circadian cycle that he had managed to power-up since his teenage years. Besides being really restorative, his sleep allowed him to memorize things much more quickly and produce a lot of Growth Hormone, further strengthening him and making his skin much more healthy and resistant.

Despite this, his body and mind remained alert most of the time during the night, boosting his already almost animal instincts. Every strange noise and fluctuation was analyzed and processed by his brain, waking him up at the slightest suspicious sound. Even today, this ability had never deceived him; even with someone sleeping next to him or on rainy nights, he was rarely woken up by ambient noises, but only for example, by the sound of a door opening up or the sound of prison warden clothes approaching his room.

However, on this rainy morning, what woke him up wasn't the sound of rain hitting the window, nor the wind trying to rush through it, but a peculiar sensation that he experienced for the second time in less than 24 hours; a warm and comforting moisture engulfing his fifth member, trying to protect it from the cold morning, and accompanied with discreet suction noises.

—Well… It's not... really hard to know who's doing this.

Yet, what could he do more than just appreciate the pleasure? If he talked or acted now, given Kaoruko's indecisive temperament, she would probably freeze and stop her blowjob. And, hell, no one wants that to happen.

Felix's mind was still fuzzy and slow, even though it was his first-ever morning wood blowjob. Nevertheless, thankfully for Bubble Girl, it's a fantasy of his, and the testosterone in every man is way higher in the morning, so it also applied to Felix but with even more potency. This wasn't even a morning wood for him, but more of a morning titanium.

Most of the time, this feeling was unbearable for him, but he pushed forward anyway or tried to meditate to control himself even more. Self-control was a big part of his existence, and that was slowly sucking out his energy day after day. But what about having someone that helps you with that? His train of thought stopped soon after he felt Kaoruko hungrily loving lips slowly slide on his shaft, almost reaching his root, although she choked quietly on it as if she tried to train and discipline herself to be even better at this than she was now.

—The competitive spirit women strike again... You really don't want Rumi to be my favorite, huh. I will keep it to myself for now, but that's cute.~

Seeing that he moved a little in his "sleep" and that a shiver ran down his skin, she moved her dark-blue lips upward, taking care to go more gently when she caressed his glans before putting a kiss on it before gasping to try to get some air. After putting back part of the blanket on his torso, she buried her head below it and started kissing his stomach and crotch before licking his cock from top to bottom with eagerness as she began fantasizing about him and their relationship.

She wanted to be loved and know really well how to do that, and not only thanks to sex, but her worry was justified, every woman wants to feels loved by an man that can show dominance; this is in the genes, engraved in the brain for millennia, impossible to go against nature once nature showed you what a real mate is and should be. And this little spark of domination and submission she experienced already began to change her for the better. It was an unconscious mechanism but will come the day she will beg for it loud and clear.

Kaoruko's tongue slips past her glossy lips, tracing the veins on his cock with the same clumsiness Rumi displayed the night before. She then dragged her soft lips back up his dick and continued her loving act... She noticed his somewhat ragged breathing and his tense manhood; well, of course, HE didn't know, but she was working his masculine gear for more than half an hour, so yeah, he actually lasted really long even in his sleep.

The sidekick gagged a few times as she tried to increase the pace of her suction and come-and-goes; her technique was way better than Rumi's; she knew it because of the time the rabbit-girl needed to make him breathe like this. She unconsciously praised herself and tried to do even better, but before sucking him again, a few large spurts of sticky and sour cum flew into her mouth, making her gag again, further enticing the lusty smell of his pheromones. The first taste of freshly harvested baby batter took her by surprise... Was it tasty? She didn't know.

Remembering what her rival had done the previous night, she gulped with difficulty the white goo inside her mouth and pulled her messy and drooling lips from his cock, panting and sweating because of the effort this 30 minutes of blowjob required from her.

"I'd... better take a shower before he wakes up…" she whispered for herself, unaware of the truth.

As she took the same clothes as the day before, Felix looked at her ass with an urge to jump from his bed and take her from behind by surprise, but this wouldn't be a great idea; she doesn't seem to be this type of woman. Plus, if he could have her trust in addition to her desires, then he could also use her quirk and relationships to achieve his goal and love her in his own way.

Even for him, love is an essential part of life, but why with just one woman?

—Well, if the women are okay with it, it's not a problem.

Manipulative? Pernicious? Cheater? Maybe he was partially all of that; Felix himself wasn't sure how he felt about his own doing, sometimes feeling uneasy, then joyous about it. Despite boosting him, this was also the somehow strange power of hormones that influenced him on a daily basis, stimulating the chemical in his brain. Even if this moodiness was only in his mind and didn't transpire on his temperament, it sometimes forced him to question his choices and actions, balancing his way of thinking to not just be an alpha male thinking only with his dick.

And with his goal in mind, he never lost sight of the essential. After all, what's wrong with wanting to fix the issues of a society plagued by simps and other human miseries?

Quirks aren't the main issue; this is just a part of human evolution. Wanting to destroy or remove it like some American scientist tries is destroying a part of human biology, stealing what nature gave to humanity.

—And I think we already disrupted nature enough to let it do its job for once. Even if this is a virus, our bodies have grown to live with it, so we must evolve with it and learn how to overcome its harmful effect…

"Errh… So that's what post-nut clarity feels like, huh," he grumbled, sitting on the bed while the sound of water from the shower echoed through the corridor. He then switched his eyes past the window. "Guess today isn't a jogging one."

Even during the weekend, he put nice but simple clothing on even if he didn't plan to go out, knowing that women love men that aren't just nice-looking and sexy during the night or once every full moon, like a lot of people do without thinking about how it would badly harm their relationship or marriage in the long term. Well, it also depends on how your body is built, but this is another subject. Welp, don't feel too offended right here.

The living room seemed almost empty as he passed through it to wake up Rumi, but he finally witnessed that the sofa was already deserted by the rabbit-lady. The seats weren't warm anymore, revealing that she left the place quite a while ago and in a hurry judging by the cushions laid out on the ground and the carpet bent on itself. A note written in haste on a post-it was stuck on the coffee table, the only element present.

{I was called for an emergency, sorry to leave so early. See you later.}

Cold and swift. Like Rumi was with him in the first few days they lived together. But for her to act so abruptly, this emergency probably got on her nerves, probably something related to her job and the issues she has since they fought in the Underground Masquerade. Maybe giving her what she wanted the previous night could have been better for her, she would be calmer and more willing to work, but at least he has a way to keep her around him now.

Felix crumpled the paper, threw it in the wastebasket, and then prepared breakfast, the simplest one for him and Kaoruko. At only eight o'clock in the morning on a Saturday, they still had some time left to share together since, as a sidekick, she wasn't working during the weekend like most heroes. And he knew how to use this time effectively after he had already boosted the hormones produced by the ovaries last night. Despite being a sex beast, he knew how to keep a clear head. He had a bad feeling about what will come next, so it was better to keep Kaoruko close to him for her to feel some real affection and not just a desire to fuck him silly.

But for this to work, he also needed to never acknowledge the fact that one of the women he was with was a girlfriend; joking about it to provoke a reaction can be a great thing, but making some of them his girlfriend right now would be a bad idea. Suppose Kaoruko or whoever the fuck thinks she's dating him. In that case, the work is done without breaking a sweat because she will talk about it to her friends, further inflating her ego and increasing other women's curiosity.

A man who's said to be in a relationship, even without him saying it, is far more attractive for them. It's taboo, and like incest for men, a cheating relationship is a common women's fantasy, like: "He chose me and not his girlfriend, so that means I'm better than her. I deserve him more than she does.".

—Yeah… Ego is one of the most important things for a girl… even for the timidest ones.

He concluded after seeing Kaoruko enter the living room as her short ruffled hair flattened a bit on her head; her yellow irises fixed him for quite some time as she came to eat breakfast with him after turning on the TV.

"F-For how long have you been awake?" she asked with a fleeting gaze.

"I don't really know. Maybe ten minutes, I first thought I was alone after not seeing you or Rumi inside the house," he explained as he gave her some jam to put on her bread. "She received a call from someone and had to leave as soon as possible."

"O-Oh, really, so that's just the two of us." Kaoruko stuttered by crunching into her toast. "I never thought I would someday encounter the female rising star of our country… even more in this kind of situation…"

"Hahaha! Yeah, that also exceeded my expectations."

"Your expectations?" she interjected as her eyes widened. "What do you mean?"

"I wanted to spend time with you, but you also allowed Miss Mirko to come with us." he deftly said with a half-lie half-true statement. "By the way, on a score of 1 to 10, how would you rate our night performance?" Before he could have an answer, he got gently kicked and punched as her cheek became purple, showing once more her pretty face blushing. "I'm just joking, calm down-"

"Nine out of ten!"

"Not even ten out of ten?" he asked with a smile, trying to hide his surprise at her impromptu answer.

"You left me exhausted and all, and…" she said as her voice became more and more quieter. "And..."

"Yeah?"

"W-What if I get pregnant…? It wasn't a dangerous day, but..." she panicked, trying to put into word her worries. "My family, and-"

"I would give you my support; I'm the one who did this. But the choice is yours if you ever end up pregnant," Felix said with a reassuring smile; he already knew that she had a shallow risk of being pregnant since he managed to block the production of the luteinizing hormones in her body—hormones in charge of the ovulation—; but a small risk was still here. "If that ever happens, I will not run away if that's what you worry about."

"Despite all these nice words, you still made love to another woman… and you're planning to continue, I can feel it."

"Well, that will maybe sound a little harsh, but yes, I do not belong to you."

"So it's the same for me…?"

"The real question is, 'Do you really want another man than me in your life.'" he answered with a shrug after drinking his tea. "But yeah, I like you enough for wanting you to stay with me."

"W-Well… that's good to hear… but… I think you need to explain yourself… 'cause, isn't that hypocritical?"

"Yes, it is." Felix simply said by looking her straight in the eyes to penetrate her heart with his words. "But everyone is hypocritical. I want only the best, like everyone, and I don't feel like sharing my women… I don't want to end like my father. Drunk, amorphous, because of a lack of everything, beating his own child because he cannot face reality and make efforts to change. I want to be the complete opposite... So, if I can make you, Rumi, and other girls in the future happier and more fulfilled than with any other man, I will do it with no shame." he trustfully explained, knowing that in exchange for the trust he gives her by telling her a little about his past, Kaoruko will provide him with some in return. "Is that a good explanation to you?"

"Well… I… Umm…" Kaoruko stammered as her whole face turned purple, almost the same color as a blueberry.

"Plus, it's in our brains; men are polygamous creatures, and women hypergamous ones... I just want to create the perfect me, and the perfect you, the perfect Rumi or more ultimately several perfect women even if it requires me to be hypocritical."

"Y-You and your damn scientific explanations!"

Bubble Girl didn't expect to get such a detailed and honest answer, and especially her partner's gaze was locked on hers from the beginning. This isn't something Japanese people are used to. How could she respond to a man who knew what he wanted in his life and had a precise goal in mind...? She closed her eyelids and sighed to retrieve her calm, but Felix got up to get behind her and do the same thing he had already done several times to Rumi: a hormone boost and an analysis of her statistics, of course.

"Don't move, please. It's a painless process that I need to do to use my quirk on you and make you more powerful."

"Yeah... You already started this with me the first time, huh? Usagiyama-san also explained this to me yesterday afternoon... But… Is my body going to be altered because of this...?"

"Not immediately, but in the long term, your body will become more muscular, have better skin quality, be more enduring, etc. You'll also need less water and oxygen to exercise, cool stuff. But nothing harmful as long as I'm taking care of it properly."

"That will also make my quirk stronger?"

"Yes, the way to do it is by sex. So it's already good. I just need to do this, and your quirk will slowly grow more powerful and potent than before." he clarified by touching her neck. "Now, just tilt your head a little, so I can 'touch' the gland in the back of your head."

She obeyed and shuddered at the touch of the young man touching the hollow space between her nape and her skull.

—Somewhat frail, but with a quirk like that, you don't have to be all in strength. Well, at least I know what I need to focus on with her. Dexterity and maybe endurance so she can use her quirk with ease. Agility can also be a great thing.

As Felix sent his own hormones directly into Kaoruko's hypothalamus, he pressed unintentionally in his mind on the line: [Perks Analyser —> Kaoruko Awata]. As soon as the line got pressed, a second text box, one he didn't really expect or even knew existed, appeared like a flash inside his head, leaving him unsettled.

[Congratulation for taking her virginity — {+1000 EXP.}]

He stood there, motionless, like someone in cryostasis for several seconds, trying to process his mistakes. He didn't even try to explore every facet of his system, so, of course, things would be hard for him… He was just too focused on what he knew from his old system and didn't acknowledge the fact that maybe there was even more than what he believed.

—If only I fucking thought about this before, maybe fighting in this goddamn MMA tournament would have been easier… 1000 EXP… It's like the 4 first levels in one go. Well, at least now I know what to do. But in that case, I could also earn the same amount of EXP by opening Rumi's [Perk Analyzer]. That may be why my stats got boosted like this; in this case, I just need to press the [Level] button.

[▲▼▲▼▲▼▲▼▲]

—Well, well, well, that's come in handy… but I don't know how to trigger the arrival of one of these… perks.

"We're done with this, Kaoruko-chan."

"Thank you."

He sighed and patheaded Kaoruko, knowing it would make her uneasy… Even for him, she's way too cute when she blushes, her cheeks turning purple as her eyes try to find a way to escape the situation. But she didn't say anything and just turned to the carpet, seeing something on it. She bent down to pick up the letter and handed it back to Felix.

"We must have dropped it last night," she said, switching her eyes to the TV. "Better if you read it now; maybe it could be urgent."

Felix sighed as he remembered the letter, a strange "gift" from a woman he had only met once on her first day of work. How she had gotten his name, and address was still a mystery, but given the country's heroic network, she must have several ways of doing so, especially if she puts her feminine assets on display. He opened it or instead tore it up to not waste time and looked at the two pieces of paperwork in it.

A lot of writing, a lot of ink, almost giving him a headache.

Kaoruko was right; it was indeed from Mt. Lady, and at the bottom of the first page was inlaid the seal of her freshly created agency. Everything seemed almost too professional, formal to be anything good; even the smell of the paper was also too smooth. He unfolded the first sheet, but that was only some random shit about heroes' obligations and terms, yet, the second one catches his attention, and he started reading its contents with apprehension.

≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈

{Hello, Mr. Fortier.}

{The letter won't be long, and I take the liberty of not making it too professional since you seem to be quite the opposite of that. I have my reasons for thinking that you "manipulate" the people around you, and since I have been a victim of your quirk myself, I can easily understand why Mirko is following you. Since I've done my own little investigation regarding you, this is something I've witnessed.}

{The most disturbing thing about this was the fact that you lied about your quirk when we met a few weeks ago. Nobody was there on the roof of any building, this vigilante you talked about was just an excuse. Why does this? It all seems too suspicious to be ignored, and I might talk about it to the Hero Commission if you don't follow the order written below. And you don't want that to happen; these people will not let their heroes be manipulated by a gruesome man.}

{So you will come to my agency on Monday morning so that you and I can talk and come to an agreement. In my opinion, you didn't have a choice.}

{See you Monday.}

≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈

—Eh?~ This thot is way sharper than it seems.~ Too bad I have the Hero Commission and Kaoruko with me.~

——————————————

A/N — Hey î_î I would like to know your opinion on a possible new fan-fic (with smut stuff of course) as I will have much more time to write. It's just some idea for later, I'm planning on working on this story first and then do this. I already started to think about some different scenarios for each. But your idea and choice can help me going on the right path. Here the list:

—League of Legends. [A lot of waifu, world-building, power, etc. My preference for the moment. Amumu would be the MC.]

—Overwatch. [EZ Clap. We go AGANE.]

—Nier Automata. [Some nice ideas about this.]

—Berserk. [I mean... this one is a fuck*ng gamble.]
