Hentai System in a Hentai World

"Don't you know us? My name is Hasewaga Haru" - Haru said.

Haru was literally a loli, she looked like a primary school girl, maybe a little taller, however, her appearance was that of a beautiful woman, long hair, tied in a ponytail and silver in color, blue eyes, she was wearing the academy uniform and a lab coat.

"It's unbelievable that there's someone who doesn't know us, anyway, my name is Hasewaga Aki" - Aki said.

Aki looked just like her sister, only her hair was short and bob-style, but other than that, they were wearing the exact same clothes.

"It's a pleasure to meet you both, my name is Ichinose Haruto" – I introduced myself.

The girls blushed for a moment, but they quickly recovered.

"Ehem, whatever, is it true that you don't know who we are?" - Haru asked.

"... Hmm, I don't want to be rude, but should I know you?" – I asked without understanding.

Seriously, in hentai I know they were clever, but apart from that, are they famous in this school or something?

But Haru and Aki were surprised, was there really anyone who didn't know them? Where did this boy come from, from the medieval or something like that?

"Hello, Haruto, thank you for coming" – said a voice suddenly.

It was Sena, which had come out of a door, it could be the bathroom or something.

"Don't worry, I've come because I promised to you" - I said with a smile.

"Sena! how is it possible that this guy doesn't know us?" – Aki asked blankly.

"That's right! where did you get this boyfriend?" – Haru asked curiously.

Hey, that's kind of cruel.

"Don't blame Haruto, he's not very interested in those things" - Sena said without giving it any importance.

"But anyone with a modicum of knowledge would know who we are!" – said Aki.

"That's right!" - said Haru.

"Sorry for interrupting your conversation, but could someone explain to me who they are?" - I asked.

Enough of the mystery, I want answers.

"Oh, I'll explain, they are, even if they don't look like it, those two are ones of the smartest people on the planet, maybe the smartest" - Sena said.

Hearing that, I went blank while Aki and Haru put a proud expression on their faces.

"Are you sure that's true, Sena? They don't look like that" - I said without thinking.

"How rude!" - they both said.

"Hehe, a lot of people said them something similar, let me summarize it for you..." – Sena said.

Then she briefly explained her story, apparently, the reason why this world was a little more advanced than mine despite being in the year 2015, it was them, Haru and Aki were two of the smartest people on the planet who invented not only smartphones, but also computers, chips... etc. In addition, they also invented spme of the medicines that make our lives so much easier, in short, they were extremely famous on this planet.

But then you may ask, what do two people like these girls do here, in a Japanese school? The reason is quite simple, Aki and Haru had been offered jobs in numerous universities in different countries, even intelligence organizations in many countries had tried to recruit them, but they refused because, according to them, they did not want to have limited freedom, they wanted to be free and they wanted to enjoy their school life. Although they may not look like it, they are both 16 years old.

No matter how they tried, no one managed to convince them and, in the end, they stayed at this school, which by the way was one of the most prestigious schools in Japan, Aki and Haru decided to stay here because Sena was their childhood friend, there wasn't another reason.

Not only that, but for having both of them here, the Japanese government gave to the school a huge amount of money, and the school gave both girls a laboratory with very advanced equipment to do all kinds of experiments, and obviously they didn't need to attend class.

"That's their whole story" - Sena said.

"Now that you know, you can't help but praise us like everyone else" - Aki said proudly.

"That's right" - Haru said.

"Well, it's true that they're awesome, but why did you call me here?" - I asked with curiosity.

Yes, I was surprised, but I'm not going to lavish them like everyone else does.

"Rude!" - they both said.

"Hehe, let them to tell you" – Sena said with a smile.

"Ok, can you tell me why you want me here?" – I asked.

"Ehem, you see, even though we have made some very common medicines, our knowledge about medicine falters compared to doctors and the real professional" - Haru said.

"That's right, that's why Haru and I set out to study medicine, so that we could develop new medicines to help people" - Aki said.

"Well, good luck with your studies, but that doesn't answer my question" - I said.

"You're a little impatient, you see, we've already studied the entire syllabus and with the knowledge we've acquired, we've managed to create a medicine that will give you an increase in strength, agility and endurance for 24 hours and without side effects" - said Aki.

"I see, but what does that have to do with me?" – I asked without understanding.

"Hearing this, you may think things like, 'How can you afford to get that product to market?' Or things like, 'If the wrong people find out, they'll do really bad things with that'" - Haru said, ignoring my question.

Well, now that she says it, it's true, but at the moment I don't care too much.

"You don't have to worry about that, this product is something we've developed as an experiment, but even if it works, we won't sell on the market, it's just to check it if we have talent to create more useful things" - Aki said.

"Wait, does that mean you want to use me as a guinea pig?" - I asked.

I see, its purpose was the same as hentai, so I guess it will have the same effects, I guess...

"That's right, but not for free, we'll pay you a lot of money if you try it" - Haru said.

Then, Aki took out a small jar from her robe and give it to me.

"Drink this, don't worry about the side effects, we're 99% sure there won't be any" - Aki said.

Damn, I don't want to do this, but... Seeing their bodies and the mission, I have no choice... Please make it the same as the hentai, please don't kill me.

"Ok, I'll do it" - I nodded.

"Go ahead" - Haru said.

Then I removed the cap from the jar and drank it.

The truth is that its flavor was quite good, it tasted strawberry.

Seeing that Haruto had swallowed his medicine, the three girls looked intently at Haruto for some change, but nothing happened.

"It looks like you've been a failure..." - Aki sighed.

However, at that moment, the voice of the system echoed in my head.

[Attention, the host has ingested a medicine that increases all his stats by 3 points, however, it has an aphrodisiac effect, the host is advised to remove the effect of the aphrodisiac or it could be harmful to his body!]

"Wait, I feel something, I feel the energy surging into my body, I feel... Good" - I said.

The girls seemed to rejoice, however, the next moment, my face flushed, I started panting, my arousal grew by the minute, and my cock got harder than a rock.

"What?" - said Haru and Aki in surprise.

"Wow, it was actually an aphrodisiac" - Sena said a little astonished.

"My body feels... good" - I said as I gasped.

But my reasoning was slowly fading away.

"We seem to fail" - Aki said.

"We'll have to start from the beginning" - Haru sighed.

They were about to leave, but Sena stopped them.

"I'm afraid that now that you've caused this, you're going to have to fix it" - Sena said.

"What? He's your boyfriend, just fuck him" - Aki said.

"I could, but do you think I can do it alone?" - asked Sena.

They looked at Haruto and it was indeed impossible for her to do it alone.

"Ok, we'll do it" - Haru said.

"It can't be that hard" - Aki said.

What they both didn't know was that after that day, they would never be the same again.
