Heroine who just got to earth

[Quest: Beg Eiji Seiya to take off his pants and play with his little brother. (Make him satisfied with your body)

Reward: A photo album of your little sister, Sona Sitri from the original work (This is a photo album that shows 200 photos of your sister in various outfits and poses that you'll love.)

Time limit: Must start 30 seconds from now. (If you are late, the quest will be considered failed and the system will automatically let your sister know that you secretly steal her panties a few times every month.

There is also a little extra information that you also like to sniff her panties before going to bed.

The choice is yours, host).

The choice is in her hands? She sees no choice at all!

These are the quests and threats that the system gives her.

If he could, Serafall wanted to freeze this so-called system woman with her "Celsius Cross Trigger". However, she unfortunately knew that she could not do anything about the other party.

She could only accept!

She had to complete the quest because otherwise she dreaded to think of what expression Sona would make after knowing what her older sister did.

The things about the girl's cosplay photos that she had hidden were fine, Sona had just confiscated them and wasn't too mad at her back then.

But what about the "few" panties she had secretly hidden in her secret room? Serafall was afraid that Sona would feel very disgusted with her.

Although Sona already knew her affection for her, she had no idea how deeply she felt for her to do such a perverted thing with her panties.

This... This is so bad!

Serafall didn't really hate doing quests and was even excited about the rewards she would get later. She was curious as to what Sona's photos of her original work looked like. The original work? After eavesdropping on Eiji's inner voice all this time, she knew those photos must be photos that Sona had never taken in this world: but photos from her own franchise!

Actually she didn't care where the photos came from, she was just curious and excited to see photos of Sona in various outfits.

But in order to get those pictures, a siscon like herself was willing to throw away her Demon King's last dignity and kneel down while letting a man fuck her mouth.

And that was still done on the stairs leading to the school roof where someone could have seen her embarrassing moment.

Even so, it was still very quiet up there so far, just the two of them. Serafall was trying to do it as fast as possible, but slowly she was also actually starting to enjoy the taste of cock inside her mouth.

The things about the reward system and younger sister were also pushed out of her mind. Now she was only thinking about the penis!

A man's penis!

Eiji's big, long and throbbing penis in the mouth, which made the feeling of humiliation in her heart subside replaced by pleasure.

Ah! So this is what a man's penis feels like!

In just under 3 minutes, Serafall felt that her panties were wet, she had already orgasmed just because of the stimulation provided by Eiji's cock that clogged her throat.

Serafall felt like vomiting because of its length and girth, but that painful feeling actually made her orgasm faster than masturbating while thinking about her sister.

Serafall felt addicted to this feeling.

Feeling Eiji's hands holding her head and even grabbing her hair impolitely. Serafall was not angry, she was even more excited and let the boy move her head back and forth as he pleased.

"Serafall... No, Onee-chan. I cum."

Glancing up, she saw the look of pleasure on the boy's face. Serafall who heard that boy calling her "Onee-chan" in this situation again orgasmed.

"Hnnm~!"

With her mouth gagged, she let out a submerged moan accompanied by an obscene wet sound as hot liquid began to flood her throat.

Serafall widened her eyes, this was her first time drinking a man's cum and she was surprised it tasted different than she imagined.

This flavor... Isn't this strawberry flavored?!

The last of the disgust in her heart gone, she willingly swallowed the sperm that Eiji kept shooting in her mouth. She almost vomited because there was so much of it, but she managed to swallow it all in the end.

"Good Onee-chan... Good job, you didn't spill any."

Serafall for the first time saw Eiji smiling gently, stroking her head and even complimenting her. There was a happy feeling that swelled in her heart, she narrowed her eyes and saw the boy's fondness for her increase.

[Favorability: 55]

What?! Although it had increased a lot, but Serafall was a little disappointed because what she had done so far was still not enough to make Eiji really like her.

She had the urge to make Eiji like her as much as possible!

She wanted Eiji to look at her with that kind of gaze more and praise her more!

This time not because of her younger sister, but because she just wanted to do it.

One of the Demon Kings, a woman who could be compared to the "Strongest Queen" and one of the strongest women in the underworld, Serafall Leviathan currently had a very lewd and dirty expression without her realizing it.

Feeling the still hard penis in her mouth, Serafall moved her tongue and started licking the penis again like a popsicle. Eiji still wasn't satisfied and she wasn't satisfied either, she wanted to taste more of the boy's cum!

Eiji also began to move his head again, Serafall was very happy and ignored the quest success notification from the system.

However...

*Pop*

Instead of continuing, Eiji took his penis out of her mouth. Serafall looked at the still very hard penis reluctantly, she turned her gaze to Eiji who was looking down on her.

"Eiji-chan~ Why? You're not satisfied yet, right? Let's continue, okay? Onee-chan will make you feel better~"

Eiji was still smiling but he shook his head while putting his little brother back into his nest. "Sorry Onee-chan, but recess is over. I have to go back to class soon."

At this moment, the school bell had indeed rung.

The sound of footsteps of the students going down from the roof also began to be heard. Serafall pouted, but she panicked and hurriedly got up while straightening her clothes. She also wiped the little white liquid left on her lips and licked it quickly.

[Serafall, I did not expect you to be so lewd. I don't know why you suddenly begged me to do that. But that's good, you're not as bad as I thought.]

Serafall smiled brightly at this, she clenched her small fists and thought it would be great if she made Eiji like her more and accept her as his woman!

Right now Serafall even wanted to let Eiji take her virginity and she was excited to know how good sex really was. But she had to be disappointed because at this time some students were already walking past them, some of them were also looking at the two curiously.

"Onee-chan, I'm going back to class now. Why don't you visit the student council? Don't you also want to visit Sona?"

"Un, I'll go there!"

Eiji didn't stay any longer, he and Serafall skipped lunch. Neither of them were hungry, and actually both of them were quite full, especially Serafall whose stomach was already filled with a lot of high-protein milk.

Cough, after the two parted ways in the corridor. Serafall looked at Eiji's back who was getting further and further dazed.

Remembering the things they did before, her face felt hot.

[Host, your quest is complete. You did it! Would you like to claim your reward now?]

"Yes?" To be honest Serafall had almost forgotten about the existence of the system, she just answered subconsciously.

[Ding! Congratulations host, you have successfully completed the quest from the system. Destiny child, Eiji Seiya is satisfied with your service. His liking for you has also increased.]

[The reward has been transferred! Your sister's photo album from the original work. Take this.]

A thick book suddenly appeared in Serafall's hand, her eyes lit up, Sona's photo album! She looked around, she skipped going to the student council office to visit Sona and directly teleported to the underworld.

Inside her bedroom.

Serafall jumped onto the bed and opened the photo album to confirm whether the system was deceiving her.

But no, it was completely real! Inside the album, Serafall could see many photos of Sona wearing various outfits such as maid uniforms, cat ears, nun uniforms, sheer dresses, and many other outfits. Sona also struck funny poses and even made expressions that she saw for the first time.

"So cute!"

"Kyaa~! My Sona-chan!"

"Hehehe this is really a treasure! Oh! Oh! And there are many others!"

Serafall was excited, yet strangely that was all. If it was her before, she was sure that right now she could not hold back the saliva that spilled out of her mouth at the sight of Sona who appeared cute and sexy.

But now? She was just smiling and actually she was not as excited as usual.

Serafall was confused, what was wrong with her? She gotten an exclusive photo album that contained many pictures of her younger sister. She should be so excited! But now, now...the things she did with Eiji before flashed through her mind.

Precisely Eiji's penis and it felt like, just thinking about this, Serafall was drooling.

...

Eiji was in a good mood at the moment. He attended classes as usual, studying with Lala, Yui, Haruna and the others even though the lessons of high school students were not that useful for a person who had graduated high school like himself in his previous life.

The reason he was still attending school here. It was because many heroine and protagonists were attending school here, the average heroine and protagonist in this world was still under the age of twenties. So most of them are still students.

Harem franchise, romcom franchise, supernatural franchises, dll most of them take place in high school.

There are also his girls who go to school, so why not? By the way looking at Serafall's situation through the Sub-System he installed on the woman.

Eiji was satisfied, not only because of the lewd things that the woman did with him, but also the changes that began to appear in her.

Serafall was no longer so eager to see pictures of her younger sister. Actually Eiji deliberately gave that kind of reward to see if there was a difference before and after Serafall did that with him.

And it turned out that there was, and it was quite effective. Eiji could have taken Serafall's virginity right then and there and made her crazy about him.

But he didn't, there was no need to rush. He still wanted to see her chase after him.

That's funny.

¶{Host, you're bad.}

"Well Miss System, what's the next plot? I'm sure there's more than one plot today. Can you recommend me the most interesting one?"

Eiji was obviously changing the topic, but it was true that he was asking curiously because he didn't know.

¶{You have the ability to see future plots. You still need me to tell you?}

"It's no fun if I keep using that ability all the time. I get too many details. You know, the feeling of people who are given too many spoilers? The fun will decrease and that's no fun."

Miss System understood what her host meant.

She sighed, but did not refuse what her host wanted.

As a system, these days she was also unemployed because her host didn't rely on her much except to give him rewards.

So this was it.

¶{Do you remember Yami?}

"Of course. How could I not remember my cute assassin."

That girl is not yours yet.

And are you sure you remember her if I don't mention her? Miss System knew this guy would definitely continue to forget her for a long time.

¶{The adult version of that girl just landed on earth this morning. And now that she was injured, she was still unconscious inside her spaceship because the landing didn't go smoothly. On the way to get to earth, she seemed to be chased by some villains. So he ended up like that}.

"That's a bit different from the original work." Eiji said with some surprise.

Mother-in-law... I mean Tearju Onee-san suffered so much to get to earth.

That's sad.

In the original work, the woman only had trouble finding Yami's location and she managed to land on earth safely.

But what happened now? How dare those little villains hurt Tearju Onee-san? What if her beauty is diminished?!

It's decided, whoever it is. If those people meet him, he must kill them all!

¶{....} Miss System certainly knew what her host had just thought.

He was angry, but it was because he was afraid that Tearju's beauty would diminish.

Of course there was also a sense of caring for others, but Miss System knew her host's greed was stronger than that.

How outrageous. This is what a protagonist who knows a woman is in distress should think? She doesn't know...

{Do I also have to give you an explanation as to why the plot is slightly different?}

"No. I already know why."

Wasn't it because of the things he had done and the other franchises that were becoming one in this universe? Eiji knew it was some kind of butterfly effect and not the first time something like this had happened.

Now the only problem was where exactly was Tearju located?

...

In a forest.

There was a twenty-meter-wide explosion site with a white space ship in the middle.

It looked like a giant ball the size of a house.

There was a bit of smoke coming out of it.

And at this moment, inside a spaceship that was rather dark and only illuminated by a few monitor screens flickering with red light, there was a woman in a white lab coat lying on the floor.

The woman was in an unconscious state.

Although her face was slightly pale with the bleeding in her abdomen already suppressed by the cloth.

She still looked very beautiful. With a face almost identical to Yami's, long eyelashes, milky white skin, thin lips, she had long blonde hair. Unlike Yami, she has the figure of a voluptuous mature woman.

She is also wearing glasses.

That woman is none other than Tearju Lunatique!

That was the woman Eiji had been talking about recently!

It had been almost 2 hours since she passed out due to the bumpy landing and the injuries she got from the people chasing her.

Now he still didn't wake up until...

[Hey this is bad!]

"...."

The shout of a man inside her head made her consciousness slowly gather and rise to the surface.

[I just remembered a plot today! Yami, you don't know what happened, but now... Sigh]

That annoying sighing sound made Tearju's long eyelashes start to move, her eyelids slowly opened and those beautiful emerald green pupils trembled slightly at the name of a girl she might have been looking for all this time.

[Should I tell Yami that she just arrived on earth? Forget it. I wonder how the cute assassin will react when she finds out. I'd better save her first before bringing the two together.]

[That way, can't Yami thank me and finally stop with her stupid mission to kill me?]

[Onee-san, I'll save you!]

Who exactly do you want to save?

Your rescue plan sounds a bit manipulative.

Can you say it clearly?

"Ugh... That voice. Eiji Seiya, there's no way that guy is talking about me, right? I just got to earth."

"How long have I been unconscious? I hope the people from the organization don't find me."

Tearju said with weakly, she tried to get up but it was difficult.

Judging from the pools of her own blood scattered on the floor, the reason her body was so limp must be because she had lost a lot of blood.

There was a cloth she had used to plug the wound, but it only slowed down the bleeding.

It was not enough, she was still dying.

She lay on her back as she tried to suppress the laser shot marks on her abdomen that were still oozing blood. If she could, she wanted to retrieve the wound healing serum from the spaceship storage room, but it was quite far away and it was difficult to go there in her current condition.

Was she going to die like this?

Before she met Eve?

Tearju was very reluctant, but recalled the voice of a man she had heard earlier in her head.

These few months she often heard voices in her head saying about the protagonist, heroine, and plot.

One of the voices she had just heard, she knew the owner of that voice was named Eiji Seiya. The person whose voice made the most noise in her head every day.

She also finally knew the information about Eve from the man's voice. The voices seemed to be inner voices, but she didn't know how she could hear them.

She had a little hope now.

Although the man was somewhat manipulative, she thought he was at least not the bad guy from his inner voice that she had heard so often.
