Guide to tamming vilanesses-Chapter 66: System evolution

"You really like having sex, master," Lilel commented, landing on the man’s chest right after Yumemi fainted.

Even after all that action he wasn’t tired at all. On the contrary, Shin felt his body filled with energy. It was probably because he had leveled up once again, reaching level 8 of his taming system.

Shin adjusted his position on the bed, settling into a more comfortable posture. Glancing to his side, he saw Yumemi fast asleep, her breathing slow and steady.

From the way she was curled up and completely unbothered by the world, she probably wouldn’t be waking up anytime soon.

"So, tell me everything," Shin turned his attention to the little fairy.

"Very well," Lilel smiled and made several system screens appear before Shin’s eyes. "As you can see, I’m able to administer your system for you."

The fairy then proudly explained that it wasn’t just about control, she could actually alter them. For example, she could fuse two skills together, upgrade existing ones, and under the right circumstances, even create entirely new skills.

"But first, you should check out your levels," she said.

[Taming System – Level 8]

{Active Skills:}

<Love Zone>

[Activation cooldown: Once per month.]

[Effect (Radius: 5m): Intensifies pre-existing attraction in female targets. Lowers inhibitions and subtly alters perception of normative behavior. All intimate acts performed within the zone yield bonus experience points.]

<Love Essence>

[Activation cooldown: A one-week period without ejaculation is required to infuse the semen with the effect.]

[Effect (Vector: Ingestion): Infuses biological matter with potent psychoactive properties. Upon consumption, it induces a temporary "Infatuation" state for 24 hours. Target exhibits unwavering devotion and pleasure-seeking behavior toward the user.

Note: High mental resistance may negate the effect.]

<Desire Aura>

[Effect (Passive): User constantly emits a low-frequency pheromonal signal. Increases the baseline attractiveness and receptivity of nearby females. Prolonged exposure gradually lowers resistance to romantic or suggestive dialogue.]

[Tutorial Mission: Conquer Hearts]

[Objective: Increase relationship depth, engage in romantic encounters, or establish sexual connections with female targets.]

"As you can see, I did a lot of work. I gathered the best versions of all your skills."

"That’s really impressive," Shin murmured, too shocked to say much more.

He recognized the abilities displayed before him. In the game, those were skills he could only acquire through special missions.

Besides, thanks to the <Love Zone>, Shin was almost level 10. At that level, he would unlock a very important skill.

"And what are the conditions for you to upgrade a skill? And to create a new one?" Shin asked.

"Well, I can create new skills by analyzing things. But I can’t analyze other people’s skills yet. I would need access to their systems..."

"Well, that would be impossible—" Shin stopped himself mid-sentence. Actually, it wasn’t impossible.

Right now, he didn’t have the skills or resources for that. But giving Lilel access to someone else’s system was feasible under the right circumstances. There was no way to do it with an enemy, but with an ally who agreed to it, there were possibilities.

"That will be very helpful in the future. And what about upgrading skills? How does that work?"

"Well, I use my own skill, <Analyze>. After understanding the structure of a skill, I can recode it into its best version. It’s like I’m reprogramming your system."

"I imagine once it’s at its best version, you can’t improve it anymore, right?"

"Yeah, but I can still fuse them. For example, you just gained <Desire Aura>. If you want, I could destroy that skill and infuse its effects into <Love Zone>. There would be advantages and disadvantages to that."

Shin thought for a moment. Lilel wasn’t sure what the final result would be. She could analyze it, but only after the analysis would she know the outcome of the fusion.

For now, since Shin had only a small number of skills, he decided to keep them as they were.

Finally, his eyes turned back to another system screen before him.

[Secondary System Perfect Soldier — level 3] 𝒻𝓇𝑒𝘦𝘸𝑒𝒷𝓃ℴ𝑣𝘦𝑙.𝒸ℴ𝘮

{Active Skills:}

<Soldier’s Will>

[Effect: Combat output scales inversely with user survivability. The greater the immediate threat to life, the greater the boost to all offensive parameters.]

<Master of Weapons>

[Effect: Any weapon wielded by the user performs beyond its standard specifications. Bonuses apply to both proficiency/mastery and raw attack power.]

<Combat Adaptation>

[Effect: Accelerates physical conditioning outcomes. Metabolic activity increases during exertion, optimizing caloric expenditure. Muscle protein synthesis is enhanced. Post-training recovery time is reduced.]

[Tutorial Mission: Exemplar Behavior]

[Objective: Engage in combat and secure victory. Undergo rigorous physical training. Maintain absolute discipline as a soldier should.]

<Combat Adaptation> would be extremely useful, but overall, it was just as Shin expected. Still, there was something he really needed to know.

"Then... what exactly are you?" he asked Lilel.

"Honestly, I don’t know," the fairy answered, floating lazily around him. Then she landed on his shoulder, reclining against his cheek.

She remembered how she had temporarily possessed the little girl during the fight. At that moment, she had felt overwhelmingly powerful. For a brief second, she could use multiple skills at once.

But then the connection was severed, and she was limited again to a single skill: <Analyze>.

"I tried to <Analyze> myself and discovered that I’m not your system. I’m a god-grade item. Apparently, I contain your secondary system, my own powers... and two souls."

Shin blinked, stunned. That was a lot to process.

To begin with, there shouldn’t be any item capable of granting someone a secondary system. However, god-grade items were exceptions to common sense.

In the game, there were only four items of that rank, and each possessed absurdly powerful abilities.

"However, I don’t know anything beyond that," she added with a yawn.

After analyzing so many things, Lilel admitted she was exhausted. Her glow dimmed slightly as her wings fluttered weakly.

"I’m... really tired..."

She curled up against Shin’s chest, her tiny body resting over his heart.

Shin exhaled slowly, the weight of everything settling in his mind. They could investigate more later.

Within minutes, both of them were asleep.

〇〇〇

Yumemi woke up slowly.

And soon, all the memories of what she had done came rushing back to her mind.

She was feeling her cunt burning with desire. Meanwhile, her cheeks burned with embarrassment over everything that had happened. She couldn’t believe she had cried like that and ruined everyone’s fun.

Yumemi buried her face in the pillow, raising her hips in the process.

"I can’t believe what I did!" she shouted, though the pillow muffled her voice.

The commotion woke up her brother, drawing his attention. As he slowly opened his eyes, the first thing he saw was his sister’s perfectly round ass. Her panties were completely incapable of containing her curves.

Little by little, the delicate fabric was absorbed, wedging itself between her ass cheeks. Her underwear seemed to turn into a thong.

Shin stood up, then landed a firm slap on that perfect ass in one fluid motion.

"If you don’t want me telling everyone about your pervy pictures, you better let me taste that little cunt of yours." He said, knowing that this was the perfect dirty talk to get her soaked.

’Do you want to fuck again, user?’ Lilel asked, landing on his huge cock with a smug smile. ’Well, it’s good, just so you know, all this sex is helping you lose weight, so keep going.’

Shin ignored the little fairy, and groped his sister’s ass without shame. Her tender flesh molded to his touch.

It took Yumemi a solid three seconds to understand what was happening. But soon she was all horny and pressing her ass against his hand.

A hot wave spread to the core of her body. Her cunt was so eager for that.

"No!" she screamed, getting into character. "I won’t do it!"

"You sure about that?" Shin asked with a threatening tone and gave her ass another hard slap.

It was just a regular slap, but the fact that her brother was threatening her made it so erotic. Yumemi could feel her ass burning, where Shin had left a visible mark in the shape of his hand.

She got so turned on that she couldn’t help arching her back, accentuating her ass even more.

"Looks like your body’s a lot more honest, slut!" Shin said harshly.

He moved quickly, easily tearing the delicate fabric of his sister’s panties. It was impossible to contain a smug smile seeing her little pink cunt so wet and ready to take his cock.

Her lust was skyrocketing, but she wanted to keep the act going.

"I won’t let you do it! Go away! I hate you, big bro!" she screamed, but her body told a different story.

Yumemi made no move to cover herself. She kept her ass high, her horny cunt on full display.

"It’s not like you have a choice," Shin said ruthlessly, forcefully getting into her bed and pressing her down.

The girl was considerably weaker than him, so even if she tried, her resistance would be futile. But she didn’t even try.

"If you don’t want your life ruined, shut up!" Shin said roughly, forcing her to turn her body around.

Now they could finally see each other face to face, and Yumemi’s heart skipped a beat.

Seeing her brother’s powerful eyes while they were role playing made everything so much more real. Her nipples stiffened against her shirt, almost poking holes through it.

"Your life is in my hands, do you understand?" he asked with a rough tone.

"Ye... Yes, I understand..." she said, trying to act scared, but she couldn’t stop smiling.

She was more than happy to be with her big bro forever. She would be his plaything, his little slut sister.

And she was eager for that.

"Then, if you don’t want the pictures out, you better obey my every command."

"Yes, onii-chan," she said with such a submissive tone that Shin’s cock throbbed hard.

"For the rest of your life, you’ll do as I command to protect your secret."

"Yes! Yes! Yes!" Yumemi said in what almost sounded like a moan.

Shin hadn’t even put his cock inside her yet, but she was so horny. Her cunt desperately clenched around nothing.

"What do the two of you think you’re doing at my house?"

At that moment, a voice drew their attention.

Shin looked up and saw Eva wearing nothing but lingerie, her body resting against the doorframe. Her eyes glimmered with horniness.

Shin glanced down at Yumemi, still bent over with her ass exposed. A slow smile spread across his face.

"You’re going to accept to be part of my harem, Yumemi. If you don’t do it, I will tell your secret to everyone."

Yumemi’s cheeks flushed deeper. She pouted, crossing her arms cutely, but after a moment she sighed in defeat.

"I can’t do anything... I can’t avoid it. I just have to obey my Oni-chan forever," she murmured.

Shin turned his gaze back to Eva. "You heard her. Join us."

Eva didn’t hesitate. She crossed the room in seconds, capturing Shin’s lips in a passionate kiss. When they finally broke apart, both women looked at him with identical expressions of need.

"Please," Yumemi whispered, her earlier embarrassment melting into want. "Fuck your horny little sister."

"You better give your cock to me first," Eva chimed in, her scary eyes prompting Shin to choose her first.
