Ch 15 Day 35-37 R18

(4751 words) (No proof reading for this chapter.)

- Day 35 -

After evolving yesterday, I don't feel like there is anything I need to do, nor do I want to do anything. So, for the entirety of Day 35, I just relaxed and spent time with my girls.

I did have to go deliver food to my captives, but other than that, I did zero work today.

- Day 36 -

Today, when I woke up, I decided to do some work. I just didn't know what that work should be.

I ate breakfast with everyone, then I ended up sitting outside and began thinking of what I could do. I watched on the sidelines as the girls trained together a little.

Eris in particular was having a fun time swinging her halberd around, demonstrating great proficiency and slicing through a tree with ease.

Watching her do this actually gave me a good idea of what I could do. Standing up, I called over all of the girls who were monsters and they gathered.

"What is it, Rou?" Kanami asked me with a cute smile.

I used Telekinesis to pull her towards me and kissed, then put her in my lap and started stroking her head while she giggled.

"I was wondering if you all would like me to use a skill on you, which will make you similar to a human? You will be able to have the Job system like humans and still be able to evolve."

"Will that make us stronger?" Tilting her head, Asue asked.

"Yes, it will. So, what do you say?"

After I asked them, I remained silent and waited for them to decide. Once they had given it some thought, they all nodded and accepted the offer.

So, standing up, I went to them one by one and used the [Humanization] on them. Like with Eris, they all began glowing and then turned human. Though, they weren't all that different to be honest...

The only difference, was that their ear lost their points and their skin changed to either caucasian, milky white, tanned or dark-skinned.

Not gonna lie, I think some of them looked better like this. Probably because of my previous human mindset.

The girls all looked over their appearance and most seemed happy with it, though not all of them.

"Hey, Rou? Is it possible to undo this?" Zadiris was looking at her hands and frowning, along with Basdia.

"Try willing to change back."

Nodding, they tried doing what he said and successfully turned back to their previous appearance.

"There you go."

Seeing their skin change to normal, they both sighed in relief.

...

After getting humanised, the girls went off and started training again, getting their own Job classes.

Unfortunately for me, this meant I was left with nothing to do again.

Sitting on the ground again, I started messing around with my element, creating little creatures and making them fight each other. Mostly pitting opposing elements against each other. Fire vs Water. Earth vs Air. Holy vs Demonic. You get the idea.

It was while I was doing this that I figured out what I could do, so I dispelled all the creatures and jumped to my feet.

Tapping the ground with my foot, I formed a cage out of earth and got into a running position.

With the firing of an imaginary starting gun, I sprinted off into the forest. Using my speed and senses, I went around and abducted a dozen horned rabbits, before returning and dumping them in the earth cage.

I began smiling like an evil scientist.

"Let the experiments begin!"

Putting my hand forward, I started releasing my Demonic energy and directed it towards the test subjects. Being bathed in the red and black Demonic energy, the subjects began writhing on the ground.

As they all suffered from the poisonous energy, time slowly ticked by.

After five minutes, one of the subjects died. Blood and a black liquid began pouring from all of its orifices, and it shrivelled up like a mummy.

In the following minutes, three more suffered the same fate.

By the ten minute mark, the remaining eight subjects began showing signs of mutation. Changes in body proportions. The appearance of extra limbs and eyes. And the unfortunate formation of pus filled boils. Each subject presented a different mutation.

A few minutes after they began mutating, the subjects that presented the most bizarre mutations, such as excessive growth of a limb or spewing acid that injured them, unfortunately died.

I was left with three surviving subject at the forty minute mark. I separated them and observed them individually.

Subject #1 - The subject has strengthened hind legs and increased aggression. The horn on its head has also become incredibly sharp. A successful experiment.

Subject #2 - The subject has grown to a metre and spikes have formed all over its body. Unfortunately, the spikes have formed in places that restricted movement and stabbed into its own body. Although the subject is stable, I deem it a failure.

Subject #3 - The subject has become a complete aberration. It has lost its fur and grown mismatched body proportions. The spin protrudes from its back and it appears incapable of movement. All in all, a complete failure.

I decided to wait another ten minutes for anymore changes to occur and Subject #3 began enlarging.

Seeing that the subject appeared as if it was about explode, I used [Solid Barrier] on it. And it was just in time, because a few seconds later and it did infact explode.

The barrier contained the explosion and then disappeared, letting an acidic steam into the air. Like I said before, a complete failure.

I looked at the two remaining subject and frowned. Only one out of twelve can be considered a successful, which feels kind of ridiculous. I mean, I didn't really want an army of Demon Horned Rabbits, but it still sucks.

The only thing I can think of to increase the odds of success, is to use [Holy Energy] to counter the effects of [Demonic Energy], but I theorise that they would end up fighting each other and kill the subject. I suppose I could use healing of prayer magic, but then it is a matter of figuring out ratio's and timing. So many variables are involved.

Sighing, I went over to Subject #2 and punched it in the head, killing it instantly. Though, when I did so, I noticed that it was quite tough and would be decent for making it into armour.

I skinned the Demon rabbit and used my upgraded [Absorption], [Great Devourer] on the meat. A black tornado shot out from my hand and consumed all the dead subjects whole. ( A/N: Tensura. Gluttony Skill.)

[You Have Acquired The Skills [Spike Generation] and [Poison Body]]

... Needless to say, but I'm not going to be letting the girls eat the meat of Demon's.

I looked at Subject #1 and wondered what I should do with it. It was still aggressive and didn't seem too useful...

Shrugging, I got rid of the earth cage and Subject #1 instantly jumped at me with a surprising speed. It tried to pierce straight through my chest, but I caught it before it reached me.

Holding it by the scruff of its neck, I smirked at it.

"Feisty little one, aren't you."

The Demon Rabbit swung its body and kicked me in the face. My smirk turned into an evil smile.

"Oh-hohoho~ I'm gonna make you pay for that!"

I was going to torture it, but realised that I didn't know where to start. With it being a rabbit and all...

To make it easier, I decided to just use [Humanization] on it. I can torture a human easily.

Using my skill, a bright light was generated and my Demon Rabbit evolved into... A hot, dark-skinned, red eyed, white haired, bunny eared and tailed girl.

Staring at the bunny girl as she struggled in my grip, an idea came into my mind and my smile grew bigger.

While holding the bunny girl, she continously growled and kicked at me. Using [Telekinesis] and [Spider Thread's], I tied the bunny girls arms behind her back with rope like threads, bending her legs and tying her ankles to her thighs. I also tied up her breasts and gagged her.

She tried to bite through her gag and break out of the restraints, but couldn't.

I flipped her on to her front, putting her in a doggy style position and then raising the ground below her, so that her butt was at the level of my crotch.

Going directly behind her, I started rubbing her vagina using my right hand. Her pussy quickly became wet, so I stuck a finger inside and started producing an aphrodisiac inside her, causing her to start moaning with a flushed face.

I removed my finger and gave it a lick, then spanked her ass, exhibiting a loud moan from her as she came.

Grinning, I undid my pants and whipped out my throbbing cock. Rubbing the gland against her soaked pussy and luring myself with her juices, before smashing my hips against her round and soft ass.

Ignoring the trickle of blood, I started thrusting mercilessly, creating slapping sounds each time my hips hit her ass.

I don't know whether or not it was because of the aphrodisiac, but she was cumming like crazy and her vaginal walls were clamping down on me like a vice.

Usually, I am quite careful when I'm fucking the others, but with this bunny bitch, I didn't care to be so gentle. She kicked me and needs to be punished. If she survives, I'll keep her, but she can die for all I care.

Strange... I don't remember being so vicious... Oh well, I have a bunny hitch to fuck to death, so I'll think about it some other time.

Constantly thrusting into her pussy, she was moaning like a bitch in heat. Because she was feeling more pleasure than pain, I pushed her head into the ground and slammed into her, piercing into her womb.

The ground below her cracked and she released a muffled scream. However, if the waterfall of love juice was any indicator, it was a scream of pleasure.

I was slightly irritated, but what can I do about her being a masochistic slut... I just decided to continue thrusting, and thanks to the tightness of her pussy, soon came inside her.

Obviously, I wasn't about to stop though. I pulled my dick out, only for her womb to come with it, refusing to let go.

Grabbing her womb, I started moving my hand back and forth, using her womb like a fleshlight.

She actually seemed to enjoy it a lot, but so did I. Rather than stopping, I sped up my hand movement.

To increase the reaction from her, I used [Electrokinesis] through my dick and shocked her as I slammed it inside her, putting her womb back inside her.

This was apparently enough to even 'shock' her, as her whole body stiffened and spasmed uncontrollably. Her eyes rolled into the back of her head and her teeth clenched so much that she bit through her gag.

"YYYEEEEEESSSSHHHHHHH!!!" Screaming loudly, her pussy got even tighter and I came inside her again as she repeatedly orgasmed into unconsciousness.

After a minute or two, her body relaxed and I was able to free myself from her wombs grip, without tearing it off.

With my dick out in the open, I quickly concealed it again, this time in her ass.

The first thought that entered my mind upon sticking it in? DAAAYYUM!!!

Her asshole felt even better than her pussy and she seemed to feel the same, as she unconsciously moved her hips and leaked her juices.

I started thrusting and enjoying her sweet little ass to the fullest. This was still supposed to be a punishment though, so with an evil laugh, I made dick bigger while inside her.

Making my dick as big as one of those monster dildo's you see in porn, you could see it in her stomach.

Finally, I gained a negative response from the bunny bitch, as she began foaming from her mouth and her eyes were white. Wild bunny bitch fainted... Ha!

Not concerning myself with her safety, I just focused on enjoying myself.

Thrusting into her nonstop, I soon arrived at my climax again, this time filling her ass with my seed.

That didn't mean I was gonna stop though. No, instead, I upped the speed of my thrusting and pounded her even hard. I wanted to keep things interesting though, so I started changing my dick in different ways.

Forming bumps and rings, I gave my dick properties only dildo's and other sex toys would have. I also made different parts more sensitive for more pleasure.

Groaning from the new sensation, I started fucking her ass even faster, momentarily going in and out of quick time, letting me have moments of pure ecstasy that I was had hyper awareness of.

Due to the sensitivity increase, I started cumming extremely fast and in quick succession of the previous one.

I ended up cumming so much that it started to overflow. The only problem, was that my dick was too big to let it spill out, so it went the only way it could and caused bunny bitch to start vomiting my sperm.

Honestly, it was kind of... Really fucking funny!!

I'd have never seen this kind of shit in my old life.

Anyways, after making spew sperm from her mouth, I'd had enough. It is hard to keep fucking someone while laughing.

Returning my dick to its normal size, I stepped away, easily removing my dick from her gaping asshole. My cum literally pooled inside her.

Smiling at my work, I fixed my clothes, then I undid the bindings and lifted her with telekinesis, taking her into the base and dumping her in a spare room.

Leaving the spare room and entering the lounge area, I was met by my lovely mother, Serana. She had her hands on her hips like she was going to reprimanded me.

I smirked at her, walked over and grabbed her chin.

"What's wrong? Feeling jealous?"

"What is the meaning of this!? Who is she and why did you treat her like that!?" She swatted my hand away and glared at me.

With an amused smile, I stared her down for a moment, before letting her win and shrugging my shoulds without a care in the world.

"She was just one of my experiments and needed to be punished. As for why? Don't know, don't care. I was already violent, this is just a step up."

I then sped behind her and hugged her body, placing a hand on one of her tits, while the other was on her stomach and slowly moving down.

"But, don't worry. I would never treat any of you like that, unless you asked me to."

Serana moaned slightly and blushed, as she felt a tingle in her lower regions. But, she managed to control herself and lightly slapped the hand moving to said region.

"W-well, what are you going to do with her?" Coughing lightly, she tried to seem serious, but the blushing and lust was giving her away.

I continued groping her breast, playing with her protruding nipple through her shirt, as I answered.

"If she lives, I will keep her as my own, like the rest of you. But, if she dies, then so be it. I won't cry over it."

As I said that, Illia surprisingly came up behind me, hugging me with her breast press against my back and her head on my shoulder as she blew into my ear.

"Aww~ Does that mean you would cry for us?" She playfully said and rubbed her chest into my back.

I looked at her from the corner of my eye.

"Who know? Maybe I will, maybe I won't. But, I can tell you this, I'll start a slaughter for taking what belongs to me!"

"Aw, how cold~ I guess we're just things that you don't want others to break." She closed her eyes with mock sadness.

Amused, I kissed her beautiful pink lips, before speaking to her.

"Don't worry about that. I truly do love you all. Not that I understand why or how that came to be, but I do."

Illia, Serana and all the others smiled happily when they heard me say this. Illia even gave me a kiss, before separating and smiling lustfully, slipping her hand into my pants and saying. "Why don't you show us how much you love us then~?"

Letting go of Serana, who was panting from my groping and grinding her butt against be, I moved back a little.

Illia let go of me and walked around, before getting on her knees and lowering my pant, releasing my hard cock and hitting her chin.

She panted with lust and push her face against my cock, taking deep breaths and saying. "Your dick reeks of sperm and that girl~!"

I place my right hand on her head and grinned.

"Are you complaining~?"

She stuck her tongue out and ran it from the base to the tip of my penis, before saying. "Nope!" And then swallowing the full length of my dick in one go and bobbing her head energetically.

At this point, Serana had given into her lust and stripped. She came over to left side and pulled my face to hers, immediately kissing me.

I wrapped my arm around her and grabbed her ass, kneading it like dough.

Illia was taking my dick deep into her throat and skillfully using her tongue, wrapping it around the shaft as she sucker on it thirstfully.

I decided to give her what she was working so hard for and came, shooting it down her thought, but with such an amount that it also filles her mouth and made her cheeks puff out like squirrel.

She audibly swallowed my cum and moved her head back until just the gland of my dick, and started slurping on it like a straw, trying to get every drop of cum she could.

When she was done, Illia removed herself from my cock and showing me her empty mouth while sticking her tongue out.

"Thanks for the meal~" She licked her lips while seductively smiling.

Standing up, Illia lifted her dress and revealed her drenched pussy. She got close to me and lifted one of her legs up, showing impressive flexibility and balance, while using her fingers to spread her vagina.

"Now, how about desert~?" She barely had to ask, before grabbed her and easily inserted by dick into her lovely pussy.

Like that, the rest of the girls also got in the mood and stripped, before coming over to us, starting an orgy that lasted well into the night.

- Day 37 -

Today's the day bitch's! Dungeon day!!

When I woke up, I went to the kitchen and started making breakfast. Though, because I was excited for going to Velvet's dungeon, I accidentally got carried away and made too much.

Placing all the food on the table, I made my way back to the bedroom to go get the girls. I checked on the bunny and found her still unconscious, so I shrugged and left.

I woke my girls and we went and ate the breakfast I prepared.

After eating, I went down into the mine, being joined Asue. While we were down there, we were flirting a lot and that lead to having some quick anal sex. Her moans probably reached all the way to the others.

The sex was fun, but it wasn't why we're down there, so after a short break, we got back to work.

...

A little while later, we broke through a wall and found a well lit hallway. It was moments after that, that a small golem creature came our way, the long awaited Returner.

I never understood why Kanata called her a Carbuncle, when a Carbuncle is a rabbit like creature...

When she saw us, she initially panicked, but after staring at me and Asue for a moment, she seem relieved and flew over to us.

"Please, help me!" She fell midair, but I caught her and started healing her.

"Calm down. Why don't you explain what's wrong first?"

I didn't want to seem suspicious by knowing everything, so I had to ask her.

"Ah! Yes, apologies." She calmed and seemingly took a breath. "My name is Returner. I was created by my master, the great Sorcerer Velvet, to over see the dungeon he created, which just so happens to be connected to your mine."

"Okay, so what is the problem?"

I tried to steer the conversation where I want it to go.

"You see, humans have invaded the dungeon and want to take my masters treasures..." She said and looked down sadly. "Along with the jewel on my head, which is extremely valuable..."

"And why are you trusting us?"

I raised an eyebrow inquisitively.

"Because you are not humans, and my master only hated humans" She said with a polite smile.

"How do you know? We look human."

I was actually curious about this.

"I have an appraisal skill. Initially, I did think you were humans, but then I used my skill." She explained to me, before becoming serious and bowing down. "Please, I know I have no right to ask this, but as a final request... I ask that you stop the human invaders, and you can have all of my masters treasures."

Hearing her request, Asue jumped into the conversation with concern. "What do you mean, "last request"?"

Returner smiled sadly and responded. "While I appreciate your attempts to heal me, I'm afraid my core has been damaged and I won't survive much longer."

Hearing this made Asue distraught, as she grabbed on to my arm and tearfully looked at me. "Rou, isn't there something you can do?"

I smile and petted her head to make her calm down and reassured her.

"Don't worry, I got it."

Without wasting a second, I used [Humanization] on Returner and she turned into a beautiful, light blue haired girl with brown eyes.

I then used all of my healing abilities on her, just to make sure she was healed.

Returner was totally confused, having no idea of how this was possible. Picking her and Asue up, I decided to take them out of the mine, because Returner had no clothes on.

When we got there, I got Returner introduced and clothed, then explained the situation to them. None of the human girls wanted to get involved with the matter, so it was me and the rest that went down to the dungeon to deal with the human intruders.

...

It wasn't long before we found the humans and rather than talk to them, I summoned up Force Edge and cut through a guy dressed like an assassin. This is where I found out, there was a lot more power behind the sword than I thought, as a slash flew through the air and sliced apart the other humans as well.

Apparently, it was just not strong enough to cut through Demonic Ice.

I rubbed the back of my neck uncomfortably.

"Well... That was underwhelming..."

The girls didn't seem to care about that and simply marveled at my power.

Sighing, I put my hand forward and Devoured just the bodies of the humans.

[You Have Acquired [Job: Assassin], [Job: Crusader], [Job: Guardian], [Job: High Wizard], [Job: Enchanter]

[You Have Acquired The Skills [Quick Thinking], [Parallel Thinking], [Riding], [Shortened Incantation], [Chivalry], [Intuition], [Conceal Presence]]

[You Have Acquired [Demigod of War]'s Divine Protection]

[You Have Acquired [Demigod of Compass@#$-ERROR------ Your Demonic Nature Has Corrupted The [Demigod of Compassion] Into The [Demigod of Callousness]]

"..."

"Pfft..."

I started to laugh, but tried to hold it.

"Pfft-Haha-HAHAHAHAHA!!!"

I couldn't hold it, it was just too funny! I corrupted a fucking Demigod!

"HAHAHAHAHAH!!!"

I fell to the floor and held my stomach while laughing like a mad-man.

The girls were understandably confused, seeing me suddenly start laughing without a cause. They looked at each other, not know what to do, until Kanami shrugged and walked over, tapping on my shoulder.

"Um... Rou? Why are you laughing?" She asked me with some concern.

"Hahaha... Oh-"

I wiped away some tears I had, from how hard I was laughing.

"I just corrupted a Demigod is all."

When I said that, most of them didn't even understand what that meant, but Zadiris and Returner understood just how ridiculous it was.

I finished wiping my eyes and stood up while dusting myself off, though I was still sniggering to myself.

Going over to the piles of clothes, I picked up a ring that conceals the wearers status and a bag that has a dimensional storage. I, of course, Devoured them and got the alerts.

[You Have Acquired The Skills [Conceal Status] and [Interdimentional Storage]]

[[Interdimension Storage] Has Been Integrated Into [Great Devourer], Creating Subskill [Internal Storage]]

[Internal Storage - Gives the users body an infinite storage capable of holding whatever the user desires, whether it be living or not.]

A good skill is always nice to have. I decided to test it out by storing the adventures equipment. It was basically the same as Devouring them, but without actually wanting to destroy them.

I looked at Returner and smiled.

"Well, that's done. How about we go to the treasury?"

Returner nodded while staring at me with admiration.

"Y-yes! Please, follow me" She said and started leading the way.

We followed behind her and Asue happily skipped beside me. I chuckled and stroked her head, which she enjoyed a lot.

...

With Returner guiding us, we quickly arrived at the treasury, where the girls help gather all the artifacts in one spot and then stored it all away.

Once I had plundered the place, I held my hand out towards the mummified body of Velvet and Devoured him, along with everything on him. Meaning the artificial super arm.

[You Have Acquired The [God of Magic's] Blessing]

[You Have Acquired The Skills [Magic God's Wisdom], [Magic Immunity], [All Magic Affinity], [All Elemental Magic], [Dungeon Creation Proficiency], [Item Creation Proficiency], [Spirit Magic], [Space Magic], [Time Magic], [Life Magic], [Death Magic], [Arm Blast], [Spell Blast], [Attribute Echo], [Connection] And [Self-Evolution]]

And I am now God!!!

Just kidding, but I am even more OP than I was.

It might seem stupid or weird to have Devoured the arm, considering I could of given it to Serana, but why do that, when I can just make a new on for her. Plus, I really wanted that [Self-Evolution] skill for myself, it seems useful.

With our business here concluded, I ran and destroyed the entrance to the dungeon, before returning to the girls. We then made our way back to the mine and I destroyed the entrance to the dungeon from there as well.

The whole time, we had to drag a dazed Returned around with us. When we arrived back at the bases lounge, I sat Returner down and she finally regain clarity.

"Ah- What?" She looked around in confusion, before jumping up in a panic. "Sorry! Thank you so much, but I have to return to managing Master Velvet's dungeon."

She was about to leave, but I used my telekinesis and sat her down again.

"Easy there. There is no need to go back to the dungeon."

"But, I must. It was my mission from Master Velvet." She looked at me, seemingly disturbed.

"There isn't anything left to protect, so you're free now."

Although I told her she is free, she just seemed uncomfortable.

"Or... I can be your new Master~?"

I grinned at her. She seemed surprised to hear this, but then looked happy.

"If you will have me, then I will gladly serve you Master!" She excitedly exclaimed and bowed to me.

I laughed and raise her up.

"Then it's settled. But just so you know, you don't have to bow or call me 'master'. You can call me Rou or Rogue."

"Understood, Master Rou!" She smiled cheerfully.

I went over to her and stroked her head a little.

...

After looting the dungeon, I decided just for the rest of the day and play with my new magic a bit, before going to bed and introducing Returner to a whole new world of pleasure.

(Honestly, I'm kind of stumped on what to do from here, so I think I'll take a break and come back when I have a plan.)
