I Had No Choice But to Rape My Little Sister

Serena, who was being raped while in a dazed state, seemed to gradually regain her senses after I pulled out my penis.

I pressed 'Lucky Pervert' once again and the font turned gray.

It must be completely deactivated now.

The only problem now is, I'm a criminal who raped my little sister.

"It was a mistake."

Serena spoke first, stiffly facing me.

"It's okay, brother, it's because I fell in a weird way."

"…Serena."

Is Serena an angel?

She's trying to comfort me in this situation…?

"On the contrary, I should have let big brother finish… I understand."

"…."

It is true that I was tempted to do it when I held her tightly.

Just holding Serena's soft body and gently shaking her waist.

If that would have happened, the 'close-up creampie intercourse' that 'Lucky Pervert' predicted must have been perfectly realized.

"Was I… was I not good enough…?"

"Serena?"

Why is she asking me such a question?

I knew I had to choose my words carefully.

I didn't want to hurt her feelings in any way.

I have to convey that it was really, really difficult to let go, and that her vagina felt really good.

…? Is this even the correct way to say it?

Was it because we had just been so tightly intertwined?

This strange atmosphere surrounding us. The words I'm spewing, the words my younger sister is spewing, I couldn't judge whether they were normal or not, I was just committing them.

"If it wasn't good, would it have turned out like this?"

I said it, with my erect penis covered in my younger sister's vaginal juice, throbbing.

"…Wow… So this is what a man's looks like."

Serena realizes this and exclaims in admiration. She is amazed by the erect penis that still seems unsatisfied, as if it cannot forget the feel of his younger sister's vagina. 

Even to me, my new penis looks very marvelous....

This is so fucking weird, looking at it with my sister.

"Umm, shouldn't we let it out?"

"Huh?"

Serena is also confused.

"Isn't it difficult for you to hold it in?"

That's true. I really want to ejaculate. I was filled with the desire to ejaculate. I endured it with difficulty, and just managed to escape from that situation. 

But Serena continues to give off a vibe that says I can still experience that pleasure. 

It was gently scratching and crumbling my self control.

Like it was the sunshine, not the storm, that stripped the stranger of his clothes.

"…It is difficult."

Knowing well where Serena's innocent curiosity is heading, I go along with it.

"If it's okay with you, big brother… Can I release it for you?"

"..."

What is she saying? Is she out of her mind? 

Like, come on. We're siblings.

"What should I do?"

Serena sticks closely to me.

"Big brother…?" 

"Use… your hand…"

I completely surrendered to my sexual desire. After achieving a great victory, I am in a state where it is even easier to let my guard down.

Even though I tried so hard to resist it, I have become the worst big brother who not only raped Serena but also asked her to give me a handjob.

If this is the goddess's trick, then I've lost big time.

But it doesn't feel bad at all.

"Like this?"

Serena grabs my penis to relieve it.

She gently strokes the erect penis, entangled with her own juices, as instinct guides her.

The movement feels somewhat awkward, but…

It was a clear act of service.

"…." 

"…."

We silently immerse ourselves in the lewd act. I leave my erect penis to Serena, and she eagerly strokes it on her own accord.

"Because something like that happened. I'll take responsibility and relieve you."

Serena explains, blushing, as she continues to stroke my erect penis.

"Something like that?" 

"Your thing, it's getting really hard and it's looking like it couldn't hold it much longer."

Endure… it was a difficult situation indeed. I have a part of me that sees it as a reward for protecting my sister from an unwanted pregnancy. 

I look at the side of Serena's face, willingly stroking me to satisfy my sexual desires.

"Mmm… it's hot and hard…."

As she concentrates, her lips slightly pout, making her look cute.

"Like this, like this… Feels good, right, big brother?" 

"Ah…."

Yes. 

This is something new to me. I've never had any meaningful connections with girls during my school days, and never experienced love or relationships. But I've never felt regretful about it. 

I believed that my ideal partner would be a pure, untouched virgin.

I've always thought that one day, I would meet someone I love and do everything with them.

That belief of mine was being completely shattered by Serena's actions.

'Is this… is this what the sex lives of attractive guys are like?'

No, not even close, right? If attractive guys receive this kind of treatment from women every day, then have I been at a disadvantage all this time? 

I feel like I'm being swayed by this temptation from the roots. 

As I receive Serena's awkward but enthusiastic sexual service, I even find myself thinking that it's fortunate that I ended up in this world.

'Becoming a big brother…'

…Ugh. Every time I try to hold onto my reason, Serena's sexual service becomes even faster.

"This feels weird…"

She giggles slightly.

"I never thought I would do something like this for my big brother…"

Don't say that while stroking me…! It's unbearable, really. Feeling like I'm about to cum, I become extremely embarrassed.

'Should I tell her?'

Should I say it pathetically in front of Serena? That I feel like I'm about to cum? I'm completely defenseless, entrusting my penis to Serena's hands.

"Do you feel like you're about to cum, big brother?"

Serena whispers.

"It's getting bigger in my hands."

…Ugh. With Serena pressed against my side, she skillfully strokes my penis with her hand. I'm about to cum!

"Ahh."

…Flop…. Flop…. Splurt…. 

I came a lot. Serena wrapped her hand around the head of my penis and used her palm instead of a tissue to catch my semen. Serena's hand quickly became covered in cum, and the remaining semen overflowed onto the floor.

"Amazing…."

Flop…. Flop…. Splurt…. 

As Serena continued to stroke my penis, as if wanting to see more, I ejaculated pitifully all the way to the base of my balls. 

Flop…. Splurt! Flop! Flop! 

The stream of semen forcefully hit Serena's palm.

"…Wow…. It's coming out." 

"…."

What have I done? I made Serena give me a handjob? I let her pleasure me all the way, even ejaculating onto her hand?

"Are you satisfied?"

The momentary relief is short-lived. 

Just as when she was asking me, my erection returns in full force. 

Even I think I'm a pervert.

"…Big brother." 

"…I'm sorry."

I apologize, feeling sorry for myself.

"Should I stroke it once more?" 

"Let's stop now."

How am I going to face her later…? Serena showed me her hand covered in semen.

"I already got this messy on my hand." 

"…." 

"You came a lot more than you usually do, didn't you, big brother?" 

"I did." 

"That's great."

Serena gently stroked my sensitive post-ejaculatory penis and smiled.

"Maybe you thought it was still inside me. That's why you released so much, thinking you could impregnate me."

"..."

In response to the line, "Maybe you thought it was still inside me," I became even more aroused unwittingly. Serena blushed shyly and stroked my penis again.

Swoosh, swoosh, swoosh. 

It felt like she had a better grasp of the pleasurable spots on my penis than before.

"…You're not thinking about wanting it inside, big brother?" 

"Do you want to put it back inside again?" 

"...What are you talking about, you're such a…pervert!"

It seems like returning to a normal relationship is now impossible. With Serena pretending to be annoyed by my perverted sexual jokes1, she gently strokes my penis.

After ejaculating three more times from my lovely sister's hand, Serena was surprised because even though there was more semen than before, my erection still wouldn't go away. In the end, she decided to continue next time and came out.

For the record, I didn't ask for it.

Serena first said, "It's already late today, and my wrist is tired, so I'll do it again next time, big brother." And all I could do was nodding my head in guilt. 

No, in fact, I'm covered in guilt. I'm a rotten person.

I can't help but see Serena as a woman now, and she sees me as a man. 

Wasn't it just five minutes ago and now the house is in a mess?

"Get yourself together…"

"We don't have time to eat breakfast, so we need to hurry, big brother!"

Because Serena took care of my penis, she ended up starving and having to leave without eating. 

…I feel really bad and want to die.

'Is this my phone?'

I found it while searching the room. It seems to be my phone, but the fingerprint recognition doesn't work. Well, that's to be expected, right? It's also locked with a pattern, and there's no way for me to know it.

"Should I do a factory reset…?"

For now, I'll just take it with me.

"Don't wait for me, go first!"

If Serena is late because of me, it's a big problem. 

But an even bigger problem is that I don't have a proper school uniform that fits.

"These clothes don't fit properly…."

In the end, I had no choice but to put on an oversized hoodie and go outside. It smelled weird when I wore it. Damn.

"Big brother, what about the school uniform?" 

"It was dirty, so I put it in the washing machine. Let's go. You can't be late." 

"I don't mind getting a demerit2 or two." 

"No, you can't!"

A demerit or two? If those demerits are because of taking care of her big brother, I won't be able to hold my head up for the rest of my life. 

Luckily, there was a bicycle in the yard, and I gave Serena a ride on the back.

"We're going by bicycle…?" 

"What time do we have to be there?" 

"8:30!" 

The current time is… 8:18.

"Which way?" 

"That way!"

I pedaled with all my might. The Es-sol Academy didn't seem too far when viewed from a distance, but actually traveling there by bicycle was quite a challenge. But still!

"Big brother, aren't you tired…?" 

"I'm fine! Hold on tight!"

Strangely, I don't feel exhausted. I was sweating and out of breath, but I felt a sense of vitality that didn't waver. The bicycle didn't stop between speeding up and slowing down, and we arrived at the academy just in time.

"We made it. Serena, let's go inside." 

"Thank you, big brother. You're so cool!"

It seems like we arrived faster than I thought. Students in the same uniform as my younger sibling, who are on their way inside the school, are looking at me with curiosity.

"Now, where is my classroom?"

Since I heard that the buildings are divided by rank, this place was not where I was supposed to go.

"This campus is so huge."

There are 4 minutes left. It wasn't easy to find my way to the 2nd-year classroom.

[Kim Sang-hyuk, 1 minute 33 seconds 58 late] 

[1 demerit point]

….

These days, the teacher doesn't even look at me. Passing through the large front door, the panel coldly reveals my penalty points. "But still, 1 point is nothing."

I managed to protect Serena's 1 point. 

It was a small price to pay to become a cool big brother.

[Kim Sang-hyuk penalty points has exceeded 100] 

[The Disciplinary Committee will be convened. Student ID functions will be suspended] 

[Please wait for a call within the academy]

….

Accumulated penalty points… 100 points…? How the hell has the main character of this game been living? But still, it was a small price to pay to become a cool big brother… right?

As soon as I entered my rank's academy building, I received a lot of stares. Is it because I'm not wearing the correct uniform? Or because I'm good-looking? Probably both. 

Although it was an unfamiliar place, I was able to find out where my class was through the locker room that can be accessed with a student ID.

"But…"

[Student ID functions have been suspended. Please contact the student council] 

[Student ID functions have been suspended. Please contact the student council]

The locker with my name on it doesn't open. It was because my penalty points exceeded 100 and my student ID functions were suspended.

"Are you looking for something important?"

8:43 AM.

Amidst everyone dispersing for class, a confident silver-haired woman walked gracefully towards the locker room where I was standing alone. Her appearance, dressed in a clean white pantsuit with a black jacket, was so well put together that it made me admire her. The outline of her large breasts, which couldn't be restrained by the black jacket, was visible, and the tight white pants that revealed the shape of her legs indicated that she has very sensual legs. 

Even though I am much taller, her presence is intimidating.

"Kim Sang-hyuk."

Not only does she know my name, but she also knows who I am.

"Do I know you?"

I hope she's a friend.

"I know who you are. How could I not know you, the only stain in our academy?"

Hmm. She's definitely not a friend, and it seems like I made a mistake.

"Disciplinary Committee. Follow me."

As if implying that it's useless to run away, her bodyguards blocked the way out.

It referred to the MC statement calling her a pervert.

In this world, if you're late you'll get a demerit/deduction point; it'll be much clearer later in the story.
