Chapter 3: 003 : Sex

Aside from that, it was full of unfamiliar expressions.

The only thing I could barely deduce was that I was attractive, thanks to the power of the "Divine Body." Everything else was indecipherable.

First, let's wash up.

It's the initial step in not becoming a brother who is despised by his lovely sisters.

'There are so many toiletries.'

Being an only child, I had never lived in a house with this many women, so I was genuinely taken aback.

I cautiously grabbed some shampoo.

Zap!!

"Ugh!"

What is this, static electricity? It feels a bit more dangerous than that. My entire body is tingling.

As I looked in the mirror, my eyes turned crimson and I began to comprehend the event that had just occurred.

[『Detection·Crimson』Activated]

[Stella's Prohibition Barrier Magic]

[Power – D]

[Duration – C]

[Activation Condition – When that bastard touches my belongings]

... ... .

Did she set up a barrier to prevent me from touching her stuff?

I picked up the item next to it, and this time, a more potent electrical magic coursed through my body.

Fzzzt!

"Argh!"

It hurt quite a bit.

Perhaps I should just give up on washing and leave....

"Brother. What's wrong?"

Then, I heard Serena's gentle voice from outside.

I felt I could trust Serena.

"Do you know where my toiletries are?"

"Didn't you say you don't use those?"

...What?

In a house where two sisters live, they only wash with water...?

"...I've decided to wash properly starting today."

A moment of silence.

Serena spoke from the other side of the door.

"You can use mine. The one on the right is safe."

Seeing that Serena considers it safe, it seems that her brother (the previous protagonist) and Stella have had more than one or two significant fights over this issue.

Was not washing some sort of personal battle for him?

It's disgustingly filthy....

As I recalled the dirt-stained white T-shirt, I applied more force to my fingertips than usual and scrubbed vigorously.

[58 seconds until 『Lucky Pervert』]

[Touch Serena's breast]

...What is this now?

The mysterious power, Lucky Pervert, was activated out of nowhere.

Touch my sister's breast? Are they insane?

Since I didn't think of Serena as my own sister, I could have considered her a romantic interest if we didn't share the same blood.

But to suddenly touch her breasts? That's absurd.

I decided to just ignore it.

After wiping myself dry and opening the door to the changing room, that's when I realized.

Serena was still there, waiting for me.

"Serena? Why are you still..."

"Huh? Oh, I thought there might be some laundry..."

She was holding the t-shirt I had carelessly taken off and tossed aside.

"I'll do it."

I wanted to tell her not to touch something so dirty with her beautiful hands.

Before any cheesy lines could escape my lips, my body moved on its own.

And then...

"Kyaa...!"

My feet slipped.

"Ah...!!"

As I slowly fell onto the soft, dark-haired body of my younger sister...

I recalled what "Lucky Skebe" was.

A cringe-worthy trope that often appeared in old romantic comedies. Falling over and ending up entangled with a female character in an awkward yet intimate position, resulting in an embarrassing yet enjoyable experience.

In reality, it would undoubtedly be a crime.

It was impossible for a girl to blush at a sudden touch and develop a fondness for it...

"No!"

The moment I engaged all of my body's autonomic nerves and tensed up, trying not to cause any harm.

"Wait a minute..."

What if she falls backward and gets seriously hurt?

I wrapped one arm around the back of Serena's head to protect her, and with the other hand, I inadvertently grasped Serena's ample breast.

[I fortuitously took Serena's virginity♡]

What is this king-receiving system message?

"Ah... What...?"

Serena couldn't comprehend the situation and remained frozen.

I was in a similar state.

This couldn't possibly make sense... It didn't make sense... "Lucky Skeve" had manipulated the situation.

There was no end to figuring out where and how the manipulation had occurred.

First of all, a vagina isn't wide enough for an accidentally erect cock to slip in when one falls over.

Even so, Serena was entirely unprepared for sex; there had been no caresses, and there was no way she could have been wet.

Even if it was a wet, well-prepared pussy...

It was impossible to accidentally fall and insert it.

Skipping all those 'details',

Serena and I had sex.

For reasons unknown, my hard, erect cock was lodged deep within Serena's soaked pussy.

All at once, bearing her weight as well.

It could be said that thanks to "Lucky Skebe," she experienced such intense penetration without getting hurt.

In reality... it would have been a dire situation.

My rigid erection entered her delicate, sensitive depths without causing injury, instead penetrating the soft, welcoming folds of her pussy in a single thrust.

I was now groaning from an unbearable sense of pleasure.

"Ugh..."

Could it be... Serena too?

In this contrived, almost horrifying scene of lost virginity, how would she react?

Serena, disarmed and leaning back, slightly raised her purple eyes, flinching in response.

"Ah...? Ah...? Uh..."

...It doesn't seem like she's in pain. Rather, she appears to be... happy, ecstatic even.

As my cock twitches, Serena's thighs tense up as well. The stillness, surprisingly beneficial, allows my member, now more erect than ever before, to align perfectly with Serena's welcoming pussy, joining us tightly together.

"Serena, I..."

What should I say? Sorry? Are you okay? My mind is slow, unaccustomed to this new experience. The only thing I can do right now is resist the urge to move my hips.

"...I'll get up..."

Serena understands the situation and places her hand on my abdomen.

"Mm... Mm-hm... Uh..."

Serena's hips rise. Her snug, clinging pussy slides up along my cock, now so sensitive it can seemingly detect the subtlest shifts in the air's currents.

"Huh, hah...♡"

Serena lets out a gasp, her eyes glazed over. This is an overwhelming sensation for me, an inexperienced novice. My heart races like mad. This is the intimacy of a woman's pussy.

The area near the entrance is especially tight, as if refusing to let go... gripping and entwining us together.

Serena's vagina was already overflowing with wetness, as if it had been in heat even before penetration.

"It'll happen... so..."

*Thump*♡

Feeling helpless, Serena sank down.

As if by a cruel twist of fate, she slipped again.

"Uh... Uhm...?!"

The heat from Serena's panting, aroused vagina reached her lower belly.

Even for me, who was experiencing sex with a woman for the first time, it was quickly apparent that her excited state was unusual.

"Oppa, my waist... I don't have any strength..."

Serena, unsure of what to do, started to lift and lower her hips gently,

beginning to display a teasing motion with her waist, close to sex and penetration.

"Stop... please..."

How am I supposed to endure this right now... !

"Ah... Ahh... Hah... Oppa..."

Serena, with a completely melted expression, moved her body in a way that made it unclear if she was trying to engage in sex or to pull away.

Is it because of the "Lucky Skebe"...?

Creampie, until pregnancy sex... It can't possibly continue like this, right...?

"Don't move! Serena."

I pulled Serena close and held her in my arms.

"Yes... yes, yes..."

Serena grew increasingly excited, trembling as she reached her climax in my arms. I had picked her up to keep her from shaking her hips, but her vagina clenched around my manhood unexpectedly tight. Unable to move, Serena asked,

"Am I being... raped by my brother...?"

How could she ask that with such a sweet voice? I had let my guard down for a moment. This world was "Yagem"...

I should have taken the world of "My Ero Academy" more seriously.

[_"Detection/Red"_ activated]

I could see it. The threads of Lucky Skeve. A red skull controlled Serena by connecting red threads to her head, arms, and legs. Those threads were also connected to my body.

Holding my sister with one arm, I swung my free arm violently and tore the threads.

"Begone!"

With the boldness of someone driving away a sea monster through sheer force of will, I protected my sister... from my own erection!

"..."

Serena, held in my embrace and sitting face-to-face, trembled with happiness.

'What should I do about the aftermath?'

It seems I'm rather in a predicament.
