Mutagen

The Succubus and Incubus Races were Demons dreaded by many because of their ability to charm people and drain their vitality for consumption.

A person whose vitality was absorbed would likely have a shorter life span, become sickly, and die from illnesses in the worst cases. That was why humans, a race that had short life spans, were afraid of these lust-invoking demons.

However, while humans feared them, it was different in the Demon Realm, the darker depths of the Spirit Dimension.

In the place where most Demon Races resided, the Succubus and Incubus Races were among the weaker ones. They did not have the physical or magical strength of other demons. That was one of the reasons why their race could never be independent and was always under the rule of someone stronger.

If they were not under someone\'s protection, the worst things could happen. After all, among the Demon Races, the Succubus and Incubus Races possessed the beauty that other races did not have. It was not hard to imagine what things their race would undergo in a place where the only law was someone\'s strength.

And hearing those unsettling noises behind the closed door in front of her, Il\'vella could not help but feel afraid.

What if Mark planned to do something like that from the start? What if that was the reason he brought her back?

She did not know what to think of it.

Yes, she was used as a bargain and became Luserio\'s woman. It was not all because she wanted to do so, but it was her task. It was her mission. And even if that was the case, just by standing beside Luserio, she had freedom and luxury. Unless everything fell, no one could threaten her.

Unfortunately, the plan failed. Moreover, most of the Demons in the Kingdom of Black Duendes died. No, they got massacred than just dying.

And now, would she become a slave for pleasure?

While those negative thoughts stormed her mind, she heard an audible sigh from in front of her. That was when Il\'vella realized that Mark was already looking at her with an annoyed expression.

"Don\'t think about unnecessary things. I already said earlier. Behave, and nothing will happen to you. Are you not listening?"

"Y-yes, sorry."

Il\'vella replied.

"What is behind the door is not what you think. Take a look."

Mark said as he opened the door.

Immediately, the unpleasant whiff entered their noses. It was a smell that was not unfamiliar to a Succubus like Il\'vella. However, the scent was too strong and seemed to have a very potent effect on increasing someone\'s vigor. Even of Il\'vella, just a single sniff and her face already turned bright red.

Il\'vella\'s body started to feel hot. Of course, she knew why. She tried to contain it in. However, it was too potent for her.

That was when she flinched as someone\'s touch on her shoulder stimulated the effects of the scent on her body. She was about to lose it.

But then, a strange sensation entered her body from that hand. That comfortable sensation made her release a seductive moan as the effect of the scent vanished from her body. Il\'vella could not help but fall on the floor with her legs weakened.

"Can you stop that?"

Mark asked, totally annoyed.

"I-I-I\'m sorry!!!"

Il\'vella panicked. She also noticed that Mark was not letting go of her shoulder.

"I didn\'t expect that it will have a stronger effect on you. Odel and Aephelia can still handle it." Mark said, not minding the smell that was entering his nose. "I\'ll hold onto your shoulder for now so you won\'t get affected too much. Let\'s go in."

Il\'vella struggled to stand up a little. Her legs were a bit numb. And to frankly say, a bit wet in between. That was a Succubus for you.

After they entered the door, the moans continued from inside. Even the squishing sound was now audible.

As Il\'vella peered inside, she could not help but feel surprised.

There, a woman was present, sitting in the corner of the room, busy poking her insides with her sticky fingers. As the woman saw someone enter the room, she raised her head. Her hand was not stopping, though. However, as she saw that it was Mark that entered, a male, the woman stood up and tried to charge towards Mark.

Unfortunately for the woman, a chain attached her right foot and to the wall stopped her. With a weakened growl, her face planted unto the floor. Even so, she did not stop. She tried to tug into the chains, trying to approach Mark with high sexual vigor. However, the chains on her foot were not just for show. She could tear down normal ones in a jiff, and thus, the ones on her foot were several times thicker and sturdier.

This woman was no other than Vem. She was one of the raiders that attacked them back in Perpetual Help University and were one of the subjects of Mark\'s experiments together with her companions, Gifre and Logan. The result turned her into a lustful failed Mutator.

Mark approached Vem, lowering his body to touch her head. Vem caught his hand, though, and tried to lick his fingers. As she did that, Mark raised his two fingers and...

...Poked Vem\'s eyes.

Vem was jolted by the pain and let go of Mark\'s hand. Covering her painful eyes with her hands, she growled and rolled on the floor.

That was when Mark grabbed her head and put her to sleep. As she had fallen asleep, the scent that was coming from her also stopped, allowing Il\'vella to come closer.

The Succubus could not help but become curious at the woman that seemed to be the embodiment of lust because of her behavior.

"Is she what you want to show me?"

Il\'vella asked, poking on Vem\'s face. She could not help but look at Vem\'s body. Her body was covered with armor at some parts, but her perky chest and strangely shaved under was exposed.

"That\'s right."

Mark said as he picked up Vem and laid her on the barely used bed.

Il\'vella saw that happen and felt strange that she could not detect any sign of lust or arousal from Mark. He was basically holding onto a creature begging to be used, after all.

"Just what are you thinking?"

Mark turned as Il\'vella was not responding.

"N-nothing!"

She hastily replied and approached Vem once more.

"Um... Can I take a look at her first?"

Il\'vella asked.

"Go on." Mark made way. "That\'s what I brought you here for."

Il\'vella took a last look at Mark before concentrating on Vem.

And to say, Il\'vella herself was curious about this woman. In fact, she could sense something familiar with Vem.

Il\'vella held unto Vem. Her right hand was on the latter\'s forehead, while the left was on Vem\'s lower abdomen.

Mark watched the scene, unsure about what Il\'vella was doing. What he could tell do was that Il\'vella seemed to be injecting her magical energy into Vem\'s body.

"This..."

Il\'vella muttered with surprise. She then stood up and faced Mark.

"How is it?"

Mark asked.

"Can I ask something first?"

Il\'vella replied with another question.

"You can," Mark replied. "But whether I will answer, depends on your question."

"This woman. What happened to her?"

Such a simple question. There was no reason for Mark to not answer. As such, he told her what happened. Mark started about Mutators and Failed ones, to his experiment, creating the current Vem. Of course, he did not forget to say that they were enemies that tried to attack his group first.

Il\'vella could not help but look away from Mark after hearing what he did to Vem. She was even more scared to become his enemy now.

"I already told you what happened." Mark did not seem to care about her reaction. "Now, tell me what you found out."

Il\'vella took a deep breath as she looked at Mark and started to explain.

"I\'m not really an expert at this kind of stuff, so I\'m not too sure. But I think... This woman might have a Succubus blood on her."

Il\'vella\'s words confirmed Mark\'s suspicion about Vem. Although he told her about Mutators, he did not mention anything about Mutagen mutating people in certain aspects because of their family\'s bloodline. For Il\'vella to say it, albeit being unsure, it was already a concrete assessment.

"Um... There is another thing." Il\'vella added. "This woman had the perfect body for a Succubus. If she really had Succubus blood, she might have come from the lineage of the ancient Succubus."

"You say ancient." Mark frowned. "They don\'t exist anymore?"

To that question, Il\'vella lowered her shoulder with a sigh.

"As far as I know, they are already gone. You can say that they are our pure blood ancestors. Right now, us Succubus did not have any purebloods anymore."

"It\'s not like our lineage got mixed or something. It could not be helped considering our nature. However, that is not the reason why our purebloods got extinct."

At this point, Il\'vella sat down on Vem\'s bed, lifting her arm.

"You see this?" Il\'vella pointed at Vem\'s exposed skin and lined up her own arm beside it. "Our purebloods had lighter skin. Mine is darker because I\'m not a pureblood. Even the Succubus Races from other countries don\'t have this light skin at all. Also, that smell coming from her body, its a trait of our purebloods. That, however, caused them to become favorite slaves. They were hunted down and caught, turning into toys of other races. But into entertainment establishments for the rest of their lives."

And then, Il\'vella looked at Vem with a sad look.

"I\'m surprised that I\'m able to meet a possible pureblood. Unfortunately, you broke her mind already."

"Don\'t say it that way." Mark shrugged. "That\'s way out of context."

To say that he broke her mind. Although Il\'vella could not understand what was wrong with what she said, Mark was disturbed by it.

"Then, this will be your job."

Mark smiled.

"Job?"

Il\'vella asked, confused.

"That\'s right. Your job. I can\'t have you staying here without doing anything, right? Besides, only a Succubus knows what another Succubus needs. About the aphrodisiac she emits, well lend you some equipment to deal with that."

"That\'s..."

Il\'vella was quite unsure. After that insane display of Vem earlier, it would be questionable if she would be confident about it.

"You can do it." Mark urged. "Aside from her insatiable lust, she\'s not harming anyone. We already had one of her kind running about in the base and getting schooled properly. So if you are lucky and managed to teach her, you might have a pureblood in your race in the future."

Mark\'s words made Il\'vella gulp. Her race having a pureblood once more. It was a great temptation.

As there was nothing to do here anymore, Mark and Il\'vella left the sleeping Vem. Il\'vella still needed time to think about it and Mark was not in a hurry.

However, before they stepped out of the chambers, Il\'vella made up her mind.

"Um, Sir."

"So, you wanted to take care of her?"

Mark said, without looking back.

Il\'vella was quite surprised as Mark seemed to have known before she could say anything. It was not the first time. Earlier, she noticed that it seemed that Mark had the ability to read her mind.

Even so, it did not matter. She already decided.

"Yes. I\'ll do it. But... Will I really be safe here?"

"Don\'t worry. As long as you behave and do your job properly, you will be fine here."

And there, Mark secured another caretaker for one of his experiment subjects.

Mark tasked Joleen in briefing Il\'vella of things around the base and to bring her into the place she would stay in the future.

"I wonder if Il\'vella can turn Vem into someone like Karla."

Mark murmured as he watched Joleen take Il\'vella away excitedly.

"In any case, there was nothing much to worry about in the base for now. I better prepare for tomorrow."
