My Hormonal Control Quirk

"Yer haven't slept at all...?"

Even though he wasn't in excellent form, Felix knew whose voice it was. Rumi still dressed in simple panties and a T-shirt, was looking at him through the hallway leading to the living room, where all his new research and analysis equipment had been installed. Unfortunately, all the apartment rooms were either bedrooms or bow rooms, so he had to set everything up behind the library that divided the vast living room in two.

"Been too long since I've been authorized to use this kind of equipment. Can't help myself," Felix replied, taking his eyes out of his microscope. "I spent the night analyzing the composition of your hormones to understand better how your quirk works and how to boost it appropriately."

"Thanks to the blood test from last time?" she yawned, opening the fridge to drink directly from the bottle.

"Yeah, that's more than enough for me to understand your metabolism," he muttered as he got up from his rotating chair to fetch something from the kitchen. "I've already prepared your carrot juice shaker. Here you go."

Mirko raised her eyebrows, then bowed her head slightly as a thank you. She still didn't understand how he would help her get stronger, but what was certain was that the commission hadn't told her everything about the quirk of the person with whom she was sharing an apartment for a month.

She would eventually discover the subtleties of this man, and even if her primary desire was to make him pay for the humiliation she had experienced during the match, smashing his skull against a wall would only bring her trouble. And he also took care of the cooking and the cleaning, she had almost nothing to do, at least for the moment... She was feeling bad for him, being used like this by the government... Maybe she could help him?

"Ya should have at least got some sleep," Mirko sighed as she sat on the couch and turned on the TV. "Ya're not going to keep up with me. It's not easy to do half as well as me in a race."

"Don't worry about me. I've got more than one trick up my sleeve, and even if I don't follow you, the important thing is that I run."

"It's not your little techniques from last time that's going to make you run faster than me, ya know," she snorted without looking at him. "And what did ya do to me too? That I'd like to know..."

"Oh? You really want to know that?" he smirked, passing behind the couch and touching the back of her head.

"What the fuck are you doing?!"

"I've already explained to you that one of the only ways I can boost or analyze your quirk is through the glands in your body. I start off with the gland in your head. No need to freak out. The commission told you everything already, anyway." he told her, aware that the commission hadn't told her the truth.

She lowered her head and crossed her arms again but let it happen. Her terrible temper was sometimes punctuated with lucidity. Otherwise, most of the time, she acted as if everything needed to be lived to the fullest; even when she was watching TV, she was spirited and full of energy.

—If the Commission hadn't falsified my quirk report, she would already be much more suspicious of me. It suits me quite well, actually.~

Felix touched the heroine's head, taking care to implement hormones directly into her hypothalamus while taking some meta-hormones from her. However, the legs, especially the feet, produce between 40% to 50% of all meta-hormones. Depending on the person, it can change a lot. For example, someone who creates explosions with their sweat will have around 90% of their meta-hormones produced in their sudoriparous glands. All glands produce small amounts of meta-hormones, but it's in small quantities.

For now, his main goal was to make her hornier than ever. Pheromones, hormones, touch, evocative talk... Because of that, from day one, he could hear her masturbating when she thought he was sleeping.

—She's just like a bundle of fluff and horniness.

Felix slipped his fingers behind the rabbit's ears, noticing once again that she was very sensitive in those places, and quickly returned to the back of her head, at the gap between her skull and her neck. He concentrated on Rumi and then on his quirk, knowing that the discovery he had made during the night would benefit him in following the development of the people he would be boosting.

[▲▼▲▼▲▼▲▼▲]

—Jesus... Next to her, my current statistics are terrible.

"You've finished touching me...?" she grunted, not deigning to turn around.

"It all depends on whether you really want me to stop or not, but from the little noises you were making, I'm not so sure."

Rumi turned to him and took Felix by the neck to strangle him "gently," pulling him over the couch and wrapping her right biceps around his neck, making him struggle to breathe.

"You like to get into trouble, don't ya?"

"My... head is touching your breasts... you should be careful, it... could make you come," he said, throwing a good dose of adrenaline through his bloodstream without using his system, which allowed him to get rid of her. "You have a really fucked up temper. I'm teasing you. No need to try to strangle me for the 6th time."

She stood up with a shrug and went off to get dressed without a smile, which was quite rare for her. Except that Felix knew very well that a woman who acts differently with you than with others is a woman who has an interest in you.

And he wasn't going to let this chance go by.

The hardest thing with Rumi would be to understand how she felt, what 99% of people were incapable of doing and getting through this shell of enthusiasm that she carried around with her outside of work. He had heard from the commission that she had never had any relationship because, in her own words, she saw no need for it.

Felix didn't see the problem in making her understand and appreciate the different uses of a relationship.

Still, the most challenging part wasn't just making her dependent on sex but making her dependent on his care. He didn't want to turn her into a puppet. Still, instead, he wanted to build the foundations of a harem that he had to build for his own good, so he had to make sure that the feelings she would have for him would be as sincere as possible, whether it was about sex, or trust and possible love.

—I'm also going to get ready for this morning's jog... She's not going to wait for me.

Moreover, all this would allow him to avoid any problem concerning a possible netorare.

Even when he still lived in Canada, he always ensured that the women around him only loved him, so there would be no suffering for him and the other guys, no betrayal, no pretense. With his power, it wasn't complicated to do; it just took time, once again. And assuming that his system would allow him to make hormone cocktails and boost them in the future, it will be even nicer to do.

"So, are you coming or not?" Rumi asked, jumping up and down in front of the front door.

"This time, you decided to wait for me, huh. What made you change your mind?"

"It's just more fun to run together. I've been doing it alone for six years, so--"

"You weren't thinking like that three days ago," he replied by giving her a tap on the shoulder. "Come on, don't look at me like that; you were the one who wanted to run, weren't you?"

"Yeah, I was the one who wanted to run! If you can keep up with me, we'll have a drink tonight with my own money!"

—You're taking a risk, my dear Rumi.

[Super-Hormones Modifier — None.]

[Stored Hormones & Pheromones: 12%.]

[▲▼▲▼▲▼▲▼▲]

—With only 12% of super-hormones stolen, I should be able to hold out for about 10 minutes without any problems... that's when it's gonna get tough-

Without waiting, the heroine hurried down the stairs and ran in a straight line. As every day, if he lost sight of her, he lost the "game," but this time, he had taken precautions. He jumped up and ran behind her.

Felix wasn't as fast, but he could keep up with her, even though his legs suffered from the alteration they had just undergone. Felix had begun to study super-hormones' actions on his body, but he still had to experiment before he could conclude... so that's exactly what he was doing. He was his own guinea pig.

—The advantage of following Miss Mirko is that I can see her ass through her leggings. Just thinking about what I will do soon with it...

Seeing that Felix managed to follow her, the heroine ran even faster. Felix even wondered if she was using her quirk too enthusiastically. Her competitive spirit would get her into trouble one day or another. They ran like that for a solid ten minutes.

The route they took should have taken at least half an hour, but with their current quirks, they could considerably reduce the time of any travel. This would be even more obvious if they could jump over the roofs of buildings and houses like Mirko did when doing her heroine job.

For once, he had managed to hold his own; mixing super-hormones with hormones turned out to be even more effective than he initially thought.

—The system considers that I won a "fight," eh... So she's going to have to pay for her round.

"Ya did it! It's almost a feat, ya know."

"Yep... We'll go and have a drink this evening, won't we?"

"Well... um... about that, I'd rather..."

"What? Miss Mirko, is there something the great heroine is afraid of? And she's not keeping her word?"

"Alright, alright! Don't start defying me! Let's see who can hold out the longest against alcohol!"

[00:19]

[In a deserted street near Felix's apartment.]

"Getting drunk after just one beer, I thought you'd be tougher," mocked the young man as he carried Rumi on his back, her whole body stuck to his. "That said, you're cute when you're like that. Much more feminine than when you're trying to strangle me."

"I'm resistant to... alcohol... That beer had 95% alcohol in it! I... already told ya that!"

"Of course, of course."

"99% alcohol, in fact!"

"Yes, yes." Felix sighed as he lifted Rumi up on his back, which only caused her to spread her legs and stick her to him even more.

"Awu~."

"Oh?" Felix chuckled. "What was that?"

"N-Nothing..."

"I'm going to lift you a bit more. You're going to hurt your back if you're like that," Felix added, lifting her up again to see if she'd still have the same reaction. And she had the same response. "Excuse me, Miss Mirko, but my back is getting wet, and I don't think it's "nothing."

"PEE!"

Rumi's cry startled him. Pee...? No, it didn't smell like that. It was something friskier, sweeter. Felix closed his eyelids after seeing his apartment building in the distance; it was time to play the game. He unleashed a cloud of sex pheromones with more potency than ever before, thanks to his system's support, and moved Rumi once again on his back.

The young woman's breathing became erratic in just about ten seconds as his back was no longer just wet but moist. He slid his hands over the two legs he was holding to carry her and sighed.

"It was a long day for me, between my sleepless night, this morning's race, this afternoon's training, and then this... I'm going to go straight to sleep."

Rumi simply squeezed her arms and legs tighter around Felix, who rejoiced at her reaction and began to climb the stairs leading up to his apartment. Every movement caused by the climb up the stairs only seemed to add more sexual tension to her, while Felix was just releasing pheromones as well as small bunched clusters of hormones.

He opened the door and set Rumi down by the hallway; however, even though she tried to stand, the jets of love juice that had wet her jeans explained why she couldn't stand.

And the alcohol in the beer she'd drunk two hours ago must have already been diluted in her blood.

—I think she's drunk on something else. I didn't let her breathe for three days, too; I even heard that it had influenced her work quality.~

Felix took the heroine in his arms and brought her to her bed, taking care to undress her so that she wouldn't get too hot during her "sleep".

Seeing that she couldn't even move normally anymore but that she wouldn't ask herself what she really wanted, the former inmate was about to play one of his favorite cards when taming a troublesome woman.

"Well... Good night Miss Mirko. See you tomorrow."

Before he even took a step, a hand came and grabbed his arm and pulled him away from the door. He came face to face with a blushing Rumi who still didn't dare to look him in the eye.

He thoughtlessly joined his lips to hers without his tongue to see if Rumi would do it on her own, but there seemed to be a vestige of ego even through all that arousal. He caressed her head as one would do with an animal, like with a rabbit, something she seemed to love even though she tried miserably to hide it.

He directed his hands towards her breasts and quickly massaged her through her shirt before stopping, causing her to shiver.

He broke the kiss and looked her in the eyes as soon as he saw that she wanted to say something.

"You piece of shit..."

"I would believe you if you would have resisted, but you didn't," Felix smiles as he approaches her again, touching the white furball in her ears with his lips before whispering. "Now, what do you want?"
