39 Chapter 39 : Testing Midnight's Enhanced Body

Yugen returned home, After taking a shower, he lay on his bed, his right hand extended, gazing at his palm in deep thought while reminiscing about the feeling of Setsuna's Oppai.

After that small accident, the two were in an awkward situation for a while, but Yugen didn't expect Setsuna to be the one to break the silence first. She pretended as if nothing had happened and told him to have another sparring round.

Yugen understood she was giving him a step down, so he agreed and decided to change his strategy from defense to attack.

He didn't care anymore about gathering kinetic energy. Instead, he showcased his strength to Setsuna. He created clones of his eyes and placed them in the sky to have a bird's-eye view. Then, he easily suppressed her split body parts and quickly found the place where her head was hiding.

Later, they changed their fighting method and decided to have a close-range fight.

Yugen's fighting skills were far ahead of Setsuna's, so he only dodged and gave some advice here and there. He taught her some tips on how to punch, kick, defend, etc...

It can be said that Setsuna was without a doubt the one who benefited the most from their sparring session, while Yugen, on the other hand, didn't learn anything new. well, At least he touched Setsuna's Oppai, received 5 lust points, and gathered some kinetic energy.

Anyway, he didn't have any high expectations from the beginning about improving his strength in this kind of sparring. For him, these levels of fights are just child's play. Only by fighting ruthless villains who won't show any mercy will his skills and strength improve.

The real objective behind Yugen accepting Setsuna's offer is to get close to her and seduce her into the harem.

Don't misunderstand him, it wasn't merely Setsuna's physical allure that attracted him. It was her unwavering spirit, her courage, and her relentless pursuit of self-improvement that stirred his admiration, not to mention that she had a great 'personality'!

...

Few hours later, Yugen as usual with nothing to do decided to learn some Mating skills to enrich his arsenal, he watched the TV in great concentration learning new sex positions.

"yawwwn~~ "

Yugen heard a yawn behind him, He glanced back and saw Nemuri emerging from her bedroom, releasing a long, contented yawn. She walked with an air of ease, her body unclothed, her breasts swaying softly with each step. As she stretched, she felt a rejuvenating sensation wash over her, as though she were shedding years. All the tensions in her muscles melted away, and the pains in her back, shoulders, and neck dissipated, as if her body had undergone a complete reset.

Nemuri glanced at the learning material Yugen was watching in disbelief.

"Yugen... I didn't expect you to be interested in this kind of content."

Her surprise stemmed from the fact that throughout their entire time together, she had never known him to show any inclination toward such forbidden films. She remembered discreetly eavesdropping on him behind closed doors, hoping to catch him engaging in typical teenage behavior. Even going as far as secretly checking his browser history, she was astonished to find that her younger brother had no interest in those things whatsoever.

She understood that invading his privacy was wrong, but she couldn't help herself. Yugen had been withdrawing into himself at that time, and she feared he might be harboring suicidal thoughts. Therefore, she felt compelled to monitor him in secret to prevent any potential catastrophe.

Yugen remained silent for a moment, his attention drawn to Nemuri's magnetic bosom.

Squinting slightly, he discerned a subtle change in their appearance.

"I'm just studying how to satisfy you in bed. Forget about me for now, babe," he finally responded. "I can't help but notice your oppai seems different. They're rounder, firmer, and even wider!"

Nemuri glanced down at her chest, initially unaware of any changes. But upon Yugen's observation, she noticed the transformation. Her once sagging breasts now appeared perky and more lifted, with a fuller, rounder shape.

Gently cupping her breasts and nodding in amazement, she exclaimed, "They've truly changed! Is this really my chest? Yugen, your quirk have worked wonders, It's like the perfect surgery!"

Yugen grinned mischievously, rising to his feet and approaching Nemuri. "I need to verify it. Let me feel for myself if the sensation has changed."

As Yugen reached out his sinful hand, ready to touch Nemuri's assets, she stepped back abruptly and swatted his hand away.

"Huh?!" Yugen was bewildered. Why did she reject his examination?

With her arms crossed beneath her chest, Nemuri looked at Yugen with a smirk before declaring, "Ara ara, Yugen. It seems you've forgotten your punishment. But don't worry, I have a good memory. For the next two days, we won't engage in any sexual activities."

Yugen's eyes widened in desperation as he pleaded "Please, babe, forgive me. I promise I won't force you again. This punishment is too harsh."

Nemuri remained resolute, her expression unwavering. "No, Yugen. It's crucial for you to learn restraint. you can't always act on impulse, especially when it comes to love. you must respect the well-being of your partners."

Seeing her determined look, He understood that he won't get any pussy snack today,

He said in disappointment, "Alright, I understand."

Witnessing his disappointment, Nemuri couldn't bear it. Stepping forward, she enveloped him in a hug, her words a soft whisper in his ear.

"It's all for your own good. You're destined for greatness as a hero. But if you're always led by your desires, you might stray and tread the path of a villain. As your elder sister, as your lover, I refuse to see you fall into such darkness."

Her heartfelt words, brimming with concern for his future, stirred a warm sensation within Yugen. He closed his eyes, taking in her scent as he tightened his embrace around her.

"I admit, I'm still immature and reckless. From now on, I'll heed your guidance. If I falter, please correct me," he vowed.

Nemuri breathed a sigh of relief. "Don't worry, my young hero. I'll ensure you grow rightly and walk the righteous path."

"I'm blessed to have you in my life," he confessed.

Yugen's sincere words touched her deeply.

For a moment, they basked in the tranquility of their embrace. Yet, Nemuri's peace was interrupted by a faint frown as she sensed Yugen's hand edging towards her ass. Despite her awareness, she chose not to disrupt the moment, allowing him to grab her ass he pleased.

A smile of contentment graced Yugen's lips.

(women, huh...)

few moments later, Yugen and Nemuri descended to the basement in order to put her enhanced body to the test.

Nemuri already wore a tight fitting dark purple workout cloths that perfectly accented her curves, she exuded an aura of confidence as she approached the first machine, which is a treadmill.

Yugen stood by, clipboard and pen in hand, ready to record her data, he said : "first let's test your speed and endurance, you must run as fast as possible for the longest period of time that you can."

Nemuri nodded in determination, her eyes focused ahead as she stepped onto the treadmill. With a press of a button, the machine whirred to life, its belt starting off at a moderate pace. As Nemuri found her rhythm, her strides gradually lengthened, her movements becoming fluid and efficient.

Yugen monitored the treadmill's display, steadily increasing the speed in small increments. With each adjustment, Nemuri's pace quickened, her muscles working in perfect harmony as she effortlessly adapted to the rising challenge.

As the speed reached an impressive 20 meters per second, Nemuri felt this speed is her limit, if yugen added more then she won't be able to run for a long time. Yugen saw her signal and didn't rise the speed anymore.

The wind whipped through her hair, her heart pounding in sync with her rapid footsteps. Yet despite the intense exertion, she maintained her composure, her breathing steady and controlled.

Yugen observed with satisfaction as Nemuri continued to run at this rapid pace, her endurance defying that of an ordinary human. Minutes turned into tens of minutes, yet she showed no signs of slowing down.

After a grueling 15 minutes, Yugen finally called out, "Babe, that's enough for now."

Nemuri slowed to a stop, her chest moving up and down, but a triumphant smile gracing her lips. "How did I do?" she asked.

Yugen approached, he gave her a towel and said. "You were incredible. Your speed and endurance have far surpassed what is considered ordinary. it's double that's of a world class peak quirkless athlete. and your endurance is really scary, i must hurry up enhance myself or else I won't be able to handle you."

Nemuri chuckled as she cleaned the sweet on her forehead and asked.

"what are we going to test next?"

Yugen replied : "the second test will focus on your strength, we will measure your lifting force, and punching force."

She nodded and impatiently urged Yugen to prepare the weights for her, she couldn't wait to see how much strength she gained.

Yugen smilled at her childish act and asked her : "by the way, how much you were able to lift in the past?"

Nemuri held her chin and recalled her last record, after pondering she replied : "I think my limit was 100 kg."

Yugen nodded then he arranged a 200 kg barbell for Nemuri to lift.

Nemrui lifted the barbell easily without breaking a sweet.

she glanced at yugen and said : "this weight is a piece of cake. "

she put down the barbell and immediately doubled the weight, the barbell now is weighing 400 kg.

This time, she felt a sense of challenge. But after taking a deep breath and channeling her strength, with a grunt, she successfully lifted the barbell.

Yugen, standing behind her was in shock. He hadn't expected that just a breakthrough into Tier 1 would result in such a significant increase in strength. At the same time, he looked forward to seeing how much his strength would improve. His foundation was stronger than Nemuri's; even before breaking into Tier 1, he could lift 350 kg. Therefore, he was bound to exceed her in strength.

"I feel I can do better." Nemuri muttered to herself, She felt that she was still a little bit far from her limit, so she added another 100 kg, preparing to lift the barbell weighing half a ton.

She squeezed every bit of her strength, her veins popping up as she let out a furious scream. The barbell was successfully lifted for a moment before she let it drop to the ground.

"500 KG...this is my current limit...my lifting force increased by 400 kg... Yugen, It seems we hadn't realized yet how much strong your love enhancement is!"

"as long as you had enough sex, you could produce batches of female All Mights!"

Yugen smiled and jotted down on his clipboard her data, lifting force : 500 kg.

After recording her lifting force, the two moved to test out the next element in strength which is the punching force.

Nemuri stood in front of a metal stand with a thick spring at its core, topped with a worn leather pad. On top of the pad existed a small red screen that indicate the punching force in kilograms.

This machine is used to measure the punching force, When you punch the pad, the force travels down your arm and into the spring. The stronger your punch, the more the spring compresses. By looking at the indicator, you can see how many kilograms of force you exerted.

Taking a deep breath, Nemuri raised her right fist. As she concentrated, a subtle tingling and heat enveloped her fist, causing her to unconsciously take a quick glance at it.

"Huh?"

Nemuri's jewel-like azure eyes blinked in surprise.

She noticed a faint mist-like aura materializing around her fist. She was certain it wasn't the result of sweat or body temperature, nor was it a problem with her eyes.

She also discovered that her forearms and entire body were wrapped in an almost imperceptible, thin layer of the same misty aura.

Yugen noticed her abnormality and asked, "What's going on?"

Nemuri looked at him, then put her delicate, soft fist in front of his face and asked, "Do you see any mist-like aura around my fist?"

Hearing this unexpected question, Yugen was taken aback for a moment. He carefully observed Nemuri's fist but didn't notice the aura she talked about.

He shook his head and replied after pondering, "I didn't see anything. Maybe it's a change caused by the love enhancement?"

Yugen rolled out the possibility of Nemuri hallucinating and guessed that she may have unlocked some new power.

'could it be that after breaking through tier 1, besides the evolution in quirk, We can acquire an ability similar to Nen, the ability to manipulate life energy?'

in order to verify his guess he inquired, "You said there's a mist-like aura surrounding your fist, right?"

"Not just my fist, but my entire body is wrapped in this aura it's just thin and insignificant. It's just that when I concentrate, ready to punch, the aura on my fist becomes thicker. Now, I've noticed that after losing my focus, it becomes thin again."

Yugen held his chin and analyzed her words.

"You're the only one who can see it, and it only appeared today. The difference between us is only the fact that you got a significant power-up in your body and quirk. If I'm not wrong, then you must have unlocked a new power, a power unrelated to quirks, purely based on the body. The love enhancement was the key."

He continued, "I guess that aura might be your life energy. I once watched an anime where it had a kind of power called Nen. The practitioners of Nen are able to manipulate their life energy, and the phenomenon is the same as you. Their aura always surrounds their bodies, which helps in boosting their all-around physical capabilities."

"according to that Anime, all living being have life energy, and it's constantly escaping our bodies like a steam gushing out of tea pot, that's why most people can't control it, only those who trained hard, practiced martial arts, meditation, etc...will be able to feel it, and keep it entangled around their bodies, once this step is achieved, they acquire a strength beyond ordinary human being, and once they master certain techniques they could even use their life energy to create special techniques and abilities that are even more abnormal than quirks, without forgetting the fact that Nen is also good at preserving youth!"

Yugen talked passionately about Hunter X Hunter anime power system, that was one of his favorite anime.

Nemuri's eyes lit up, just hearing these few words she already realized the potential of this power, if the guess of Yugen is right and they truly acquired a new power besides quirks, even if it was just a little bit similar, then the possibilities are endless.

"I'm afraid that reality will be different from animations, I think it's effect won't be that good, as long as it gave us a boost in our physical strength that's more than enough." Nemuri said.

Yugen nodded in agreement, this world is obviously different from Hunter x Hunter, maybe he could reference some techniques of using life energy from it, but developing Nen abilities seems a bit far reached, he had to try and see if it's possible, he said,

"Now, let's do an experiment to see if my guess is correct. Try not to channel your aura on your fist and see how much power you achieve. Then repeat it again, but try to focus and use the life energy. If your strength increases, then my guess is correct."

Nemuri nodded, without concentrating the Aura on her fist, she punched the machine's pad. 

"BANG!"

The machine trembled, the spring compressed, the numbers on the display screen rose from 0000 KG until they reached 512 kg.

Nemuri's eyes widened in shock, she couldn't believe it, she, a woman, with no strength type quirk, could punch half a ton!

Yugen wasn't surprised, this result is within his expectation, now he is curious how much strength her fist coated in aura will have.

Yugen jotted down the data and said, "Now enhance Your first with Life Energy."

Nemuri nodded, she concentrated all her strength on her right fist just like how she did previously, the aura around her right fist concentrated and becomes a little bit thicker.

"BANG!"

She let out a deafening punch that sent echoes in the basement, the numbers on the screen danced and the result appeared after a while.

"993 KG!" Nemuri jaws almost dropped, her mouth opened wide, if it wasn't for his punishment and shock, Yugen really want to seize the opportunity and stuff his meat inside it.

He looked at the almost one ton of force that Nemuri just punched out in shock.

'so strong! sure enough, just like Nen, using life energy can indeed augment physical capabilities!'

Yugen was ecstatic, the lust empowerment brought him a huge surprise, just breaking through a mere tier 1 already showed so many benefits, he can't wait for Nemuri to go work so he can 'wash his marrow' too.

Nemuri grinned menacingly and said with a snicker : "now now now, i don't need to use my quirk any more to put villains in sleep, this fist alone is more than enough."

she turned to Yugen and waved her fist, she smiled misheviously and said, : "if you dare to be disobedient again I'll spank your ass with my palm worthy 1 TON! you must listen to my words from now onward!"

Yugen looked at the inflated Nemuri speechlessly, His position as a man seems to be in danger, he needs to show her who is the man here!

"babe, arrogance is a big sin!" 

He shoved Nemuri aside, his muscles tensing as he clenched his fist, and with a determined force, he struck the machine's pad.

in this punch he add 50% of the impact he absorbed from Setsuna attacks.

"BANG!"

The impact echoed throughout the basement, causing the entire apparatus to shudder. The indicator numbers danced before settling on a number that left Nemuri stunned.

"1015 KG! this is ridiculous! you haven't used love enhancement yet?" Nemuri shouted in disbelief, Obviously Yugen hadn't used love enhancement yet, his quirk didn't evolve, and he certainly hadn't spent half an hour squatting in the toilet like her. So why was he stronger?

"Who's your daddy now?" Yugen didn't respond with words but instead seized Nemuri by her waist, drawing her close until their bodies pressed together.

seeing her astonished expression, a sense of satisfaction washed over Yugen. Thankfully, his acquisition of Impact Absorption had granted him a surplus of kinetic energy from Setsuna's attacks, otherwise, his punch wouldn't have surpassed 500 kilograms.

Yugen made a mental note: he couldn't allow Nemuri to surpass him in strength in the future. Her sadistic tendencies might emerge if she felt superior, and though she wouldn't harm him, he bet she might forcibly handcuff him in bed and insert some of her dragon dildos in his asshole, To avoid such a predicament, he needed to maintain his dominance.

"Have you become this strong already?" Nemuri inquired, her curiosity piqued. As she gazed into his violet eyes, memories of Yugen's relentless training over the years flooded her mind. Only now did she realize the fruits of his labor, feeling a pang of shame that she, as his elder sister, guardian, and lover, was weaker.

Yugen tenderly caressed her smooth cheek, a gentle smile playing on his lips. "Darling, there's no need to be surprised. I've been training for at least five years, building my strength. Boys are naturally stronger than girls, and the love enhancement I received the day when I awakened my Quirk boosted my strength significantly."

"Now, let's proceed to the next test: your reflexes," Yugen kissed her lips and declared after releasing her.

Next came the reflex test. Yugen activated a machine that launched tennis balls at incredible speeds from various angles. With lightning-fast reflexes, Nemuri effortlessly dodged each projectile, she anticipated each trajectory with uncanny accuracy. Yugen also added his own unique challenge, utilizing his quirk to summon a barrage of cloned body parts as projectiles. With a keen focus, Nemuri evaded each attack with ease, her reflexes honed to perfection as she deftly maneuvered through the onslaught.

...

After completing the physical tests, the duo returned upstairs, indulging in their favorite series while cuddling, cherishing the warmth of each other's embrace. Following dinner, Nemuri donned her hero costume and departed for work, leaving Yugen alone at home.

Entering his room, Yugen opened the window, shed his clothes, and headed directly to the bathroom, where he sat on the toilet.

"Finally I can breakthrough with a peace of mind, but before that..." 

Yugen retrieved Boa Hancock's panties from his pocket dimension, inhaling its scent and rubbing it with his dick while imagining himself having a threesome with boa Hancock and Nemuri.

Yugen stroke his dick quickly venting all the desire he accumulated when he was cuddling with Nemuri, his Bondagani was on the verge of exploding.

after releasing his anger, and entering the sage and desireless mode, Yugen was ready to attain Tier 1!

He couldn't wait to see what kind of change his quirk would undergo, and whether the life energy could be utilized akin to Nen, or if his Superpowers gained from the system, such as Infinity Bookmarking and its derivative ability, Impact Absorption, would unlock additional functions.

Yugen thought with anticipation that after breaking through Tier 1, he must find a worthy opponent to test his limits. He already had a suitable test subject in mind, none other than the Hero Killer, Stain!

----Author notes----

Brothers, give me some suggestions for Yugen's clonaportation's newly evolved abilities. Also, what kind of new functions could be added or unlocked from the infinity bookmarking and impact absorption powers?
