Is it wrong to have a Harem System?

Haruhime's eyes widen as she looks at me like a beaten puppy, which triggered my mischievous nature.

I gave her a grin.

Seeing my grin she felt cold sweat dripping through her back.

"Nooooo…" – She screamed cutely as I placed her on my lap front on my chest.

She tried to cover her embarrassed face using her cute hands which I let her be, for now.

"You brought this to yourself." – I whispered on her ears in a teasing manner before I began licking her cute nipples while and at the same time thrusting my member inside her very depths.

Her eyes rolled feeling a foreign object penetrate her very depts without a warning.

She is still very sensitive.

She stopped covering her face as her hands moved to my back embracing me tightly trying to feel my warmth.

...

Kai and Haruhime continued to do it for the next 6 hours, nonstop.

Kai possessed infinite stamina while Haruhime was trained to have great stamina.

She even received an Extra Skill: Monstrous Stamina due to the Asian difficulty training she was put through.

They only stopped after they noticed the sunshine peeking through from the open window.

"Y-your a beast, Kai." – Those were Haruhime's last words before she shut her eyes closed, exhausted.

Kai just smiled.

Flicking his finger all the stains in the room disappear in an instant like nothing had happened.

He slowly and gently cleaned her body using a wet and warm towel for gentleman's sake before covering her naked body with a blanket and placing her in a comfortable position.

"Damn I know it will be good but not to this degree."

[Is it really that good.]

"Rafael-chan, are you curious?"

[…]

"Maybe next time my soul wouldn't be able to handle a manas right now, right."

[Yes…]

She replied in a shy voice.

I could tell that she's very dejected.

Unfortunately, we can't really do a thing about my soul until I reach Tensura Verse. Their isn't really any efficient method or item in the shop that will help my soul grow fast enough to my standard. And going to Tensura is also my dream.

For now I can only apologize to my partner as she needs to wait a bit longer.

Though I can probably allow her to inhabit a physical body.

Well, I probably need to introduce Rafael to Haruhime, and the earlier the better.

Women are quite scary if you hide too many things from them, the moment they got a wind of it you'll be in a lot of trouble just because you kept prolonging the inevitable.

...

I can feel two soft hands hugging my waist.

I looked down and saw the asleep Haruhime who has a gentle smile on her face.

Wait…

What…

I was shocked at the sight before my very eyes.

I panicked.

Haruhime's golden fur is turning bluish grey.

"Rafael-chan, what's going on?"

I quickly asked my trusted partner for an answer.

[Don't panic it's a normal occurrence.]

"Normal…"

I calmed down hearing Rafael's assurance.

[She's evolving into a higher species. You can open your system and read the effects of Harem Sub-System so you can understand better why this is happening to Haruhime.]

"Eh, I have a Harem Sub-System in my System that has it's own effects?"

I was once again surprised, I didn't think that I have something like that.

Well I've already suspected my Harem Sub-System to have effects but didn't really put it in my mind.

[…YEP…]

I opened my system interface and pressed the search icon before typing Harem.

…

…

After reading the effects of the Harem Sub-System I was gob smacked.

"Rafael-chan, How does this work, isn't 25% of my power absurd, wouldn't they become Tier 15 existence just from the boost they received from me."

[Don't worry, as that shouldn't be the case. You have two statuses. One is your Tier 17 while the other is your Tier 3. For your mortal spouses they'll received power from your Tier 3 status. And for your god spouses they'll received power from your Tier 17 status.]

"That's good, it be bad if they received a sudden burst of power. Sometimes power is a poison so earning it slowly is far better."

[*Cough* you're the one to talk.]

I ignored Rafael as I familiarized myself with the system interface.

It was usually Rafael-chan who does all the work when it comes to my system.

--- 6 hours later ---

//Haruhime POV//

I slowly opened my eyes I felt sore and numb all over my body mostly to my lower back in my butt.

Extending my hands trying to stretch my aching joints and muscles I notice that there's another presence beside me.

I quickly got up, my eyes searching for my weapon, but before I could do so it dawned upon me that there should be no one other than me and Kai that can enter this territory.

My eyes quickly shifted at the figure covered in a blanket.

Feeling an ever so familiar presence.

It was clearly Kai a 100%.

I tried to jump at him in joy but then memories of the night prior resurfaced in my mind.

My face immediately turned red.

I quickly grab the nearest thing beside me that can be used as a cover.

I was completely naked.

I was embarrassed.

My fingers crawl down to my vagina recalling the pleasure the night prior.

I was happy.

Very happy, though Kai is a beast.

My joy is overflowing recalling his rough yet soft touches.

My lust also seems to have subsided.

Finally I am accepted by someone and that someone is who I loved.

My savior, my hero.

But I felt conflicted inside.

Do I really deserve him.

Kai is someone amazing, too amazing to the point that I doubt if Kai is really a mortal.

The things he had showed me isn't something mere mortals shouldn't be able to do.

But I can't really asked him.

I am worried if I am intruding too deep.

I can't do nothing but wait for him to open up to me.

…

Sensing someone is eyeing him while he is asleep Kai slowly woke up. He didn't panic unlike Haruhime as his confident in his own barrier that protected the territory and he knew from the start that the one keenly eying him is no other than Haruhime.

Though the sign that gave her off is the tiny bit of lust coming from her gaze.

I opened my eyes.

She's slowly move back, though not out of fear but out of mischief.

She's trying to take advantage of me making it look like I've done something wrong.

I did done something wrong but you can't fool my girl.

Kukuku~

"Is something the matter, Haru-chan?" – I asked her, using the new nickname I came up with back in the demon slayer world.

"Haru-chan?"

She muttered in a baffled tone yet I can also tell that she's happy from the tone of her voice.

"You don't like the nickname I gave you. I'm hurt."

Kai disguised his voice. He makes it sound a bit dejected.

"N-no, I didn't mean it like that. I was just taken aback as you never once called other than my name."

Haruhime profusely shakes her head trying to appeal to Kai.

The positions have twitch.

I am really amazing, no woman can reign over me.

I wouldn't be a henpeck husband.

"Hahaha, don't worry I am just joking. Your too serious."

Kai let out a jovial laughter before Haruhime's reaction.

She didn't replied and just pout at the corner of the bed avoiding eye contact.

Kai shrugged the back of his head as he made use of his new [Unique Skill: Selfless State] he slowly sneaked behind the unsuspecting Haruhime erasing his presence completely.

He sent a breeze of cold air directly to her ears which prompted the poor girl to jump out of the bed in surprise due to the cold.

And as she landed Kai quickly caught her in a princess carrying a wide grin on his face.

He could see her ears twitching cutely, nonstop.

"What's had gotten into you? You should be careful." – Kai mused.

She didn't replied as she covered her face with both of her hands trying to hide her redden complexion.

Her ears are still twitching.

"Y-your so mean."

"Nah, sorry. It's just that, it felt good teasing you."

Saying so Kai gave Haruhime a gentle kiss on her forehead.

Kai carried Haruhime back to the bed and placed her small body gently atop the mattress.

"Haruhime…"

After placing her onto the bed Kai's called out her name, his tone a bit serious which prompted the little girl to take him seriously.

"Yes?" – She asked.

"You should've notice the changes happening inside and outside you."

"…huh…"

Haruhime was confused. She didn't get what Kai is implying.

She looks at Kai and sees where his eyes are she promptly shifts her attention to her tail. And there she saw it. Her once golden tail turned into glossy grayish blue.

"…"

She was surprised and was about to question him but Kai beat her into it.

"Due to our intercourse you've evolved into a higher species. Try thinking of the word STATUS."

She didn't get to respond as she just followed through Kai's suggestion.

'Status.' – She thought.
