My Taboo Academy

That outfit on the news was the exact same one she had been wearing when I held her earlier. The memory of treating an SS-class Hunter like my personal pet, patting her ass, stroking her head as refused to leave me alone.

"Brother, I brought tangerines."

Oh?

While I was still staring at the TV, Yuna sat down on the other side of me.

She carefully peeled a tangerine and held a piece up to my mouth.

"Aah..."

*Gulp*.

This was way too embarrassing.

Having both Yuna and Cleo this close was already dangerous.

And now she was feeding me

"Ah... aah."

I ate it.

"There’s water too, big brother."

"Y-yeah..."

Yuna peeled another piece.

"Give me some too."

Cleo took one, split it into smaller bits, and held them out.

"..."

"...It’s for you, brother."

"*Sigh*."

I gave in and opened my mouth again.

I couldn’t focus on the television at all. My arousal only kept climbing.

The distance between me and my beautiful stepsisters was getting dangerously small.

When it was time for bed, Yuna appeared at my door.

"Big brother... can we sleep together tonight?"

She wore cute pajamas that looked completely innocent.

The braless soft mounds underneath them were anything but innocent.

They were more than enough to destroy whatever self-control I had left.

"...No."

Tonight I drew the line.

"Why? I want to sleep next to you..."

"You’re not the only one. That kind of thing... has to stay in the past."

I couldn’t quite bring myself to say "Let’s never do it again."

This erotic game world had already ruined me.

"...We need to cut back. I have a girlfriend now."

"Brother has a girlfriend!?"

"Yes. So..."

"Hmm..."

"Good night, Yuna."

I closed the door and locked it quickly.

Yes. This was the right decision. I couldn’t keep letting my sister get involved in those kinds of things.

In a few days I’d be able to sit next to them with their hips pressed against mine and stay completely calm.

We were family. There would be plenty of harmless closeness in the future.

As for actually crossing the line and having sex...

’...’

"Brother... Cleo will apologize properly with her pussy for being so arrogant all this time..."

"Only Cleo? What about Yuna...? You’re not going to do it with Yuna too, brother?"

Aaaah!!!

I slammed my face into the pillow.

"No! No!! Aaaaaah!! I can’t!!"

"...You want both of us at the same time? Greedy..."

Sister harem sex. The most sinful fantasy possible.

Ren Asahi!!

Get those thoughts out of my head!!

Exhausted from my own imagination, I collapsed onto the bed.

’Just sleep.’

*Ding.*

I had already turned off the lights when my phone lit up.

[Elle]

Honey, you worked hard today

"..."

I reached for the toilet paper on the nightstand without another word.

---

Ever since Aria got home she had been lying on the sofa, unable to shake the hollow feeling in her chest.

Her mind kept circling the same thought, the boy she liked had been taken by her own friend.

’Taken?’

She had never even owned him in the first place. She knew the mature thing was to congratulate Elle and step back gracefully.

But knowing and feeling were two completely different things.

"Ugh..."

The heart refused to listen to reason. Aria buried her face in the pillow and let the tears come.

She kept replaying the day they cleared the Golden Orc Fortress especially what happened in the shower room afterward.

"Elle, your boobs look really beautiful."

"Uh... thanks. You’re really pretty too, Aria."

"Can I... touch them?"

Back then she had no idea Elle would become Ren’s girlfriend. She had simply reached out, sunk her hands into that soft warmth, and been stunned by how good it felt.

As a girl she wanted to be wrapped up in them; as someone who liked Ren she couldn’t stop wondering how a man’s hands would feel on the same place. The thought alone was unbearable.

"They’re so soft..."

"Ah... not so rough..."

"Sorry."

Every time the memory surfaced, Aria’s chest tightened. She should have been the one standing beside him.

She had told herself Ren would never choose his childhood friend. Childhood friends were too familiar. No matter how perfect their bodies were, they couldn’t create that spark of newness.

She, the "new girl," had the advantage. That was what she kept repeating to herself.

But Elle had always been a real rival.

Aria needed to understand exactly where Elle stood.

While the two of them were washing up that day, she finally asked the question that had been burning in her throat.

"Elle... do you like Ren?"

"Yeah. I really like him."

Elle’s cheeks went pink. She twisted her fingers together, looking embarrassed.

"Have you ever told him?"

Elle shook her head.

Even though she had feelings, she had never confessed once.

"Why not?"

"Just being friends already feels like too much. I’m scared."

"There’s no such thing as ’too close to date’! If you like someone you go for it. Only the brave ones get the handsome guys!"

"But what if I confess and I can’t even stay friends with him afterward?"

The fear of losing even the current relationship froze her.

Aria understood that fear perfectly. She felt the same way.

There was chemistry. The atmosphere was always good. But it never quite crossed the line into something she could call romance.

"I can’t say it either..."

"I figured."

"This is a real problem. Half the girls in our class already like him."

"...Ugh."

"Do you think Ren is going to end up with a whole crowd of female friends?"

"Stop saying scary things. I liked him first."

The moment they both admitted their feelings out loud, Aria thought maybe they could form some kind of alliance.

"We’re still the closest ones to becoming his girlfriend, right?"

"Girlfriend candidates...?"

"Exactly! Are you just going to sit and wait? Someone else might snatch him first."

"Aria... even if you become his girlfriend like that, what then? What’s so great about it?"

Aria opened her mouth and found she had no answer.

She was used to hunting, seeing something she wanted and taking it.

But this was the first time she had ever fallen for a boy. She had no idea what came after "capturing" him.

"We could go on dates. If I dated him... maybe the three of us could still watch anime at someone’s house every day."

"That actually sounds amazing...!"

Elle’s eyes lit up.

"And... um... some... naughty things too..."

Naughty things.

For both of them it was still a mysterious, half-imagined world. Elle’s mind immediately went to one specific memory.

The breast "discipline" on the very first day.

That short, dizzying experience had become the most thrilling erotic memory she owned.

’I want more of that... Am I turning into a pervert...?’

"But there can only be one official girlfriend."

"I... don’t have much confidence."

"Then at least the two of us can keep the other girls away."

"Keep them away? That sounds scary..."

"Would you be okay if someone else took him?"

Elle shook her head hard.

"After we protect him... then we confess."

"...You go first, Aria. I can’t..."

"M-me?!"

Aria’s breath caught.

It was easy to talk about beating other girls.

Actually confessing herself required a completely different kind of courage.

"I’ll just stay the slightly perverted childhood friend. That’s enough for me."

"There you go retreating again. And you’re not ’slightly’ anything."

Silence.

Aria’s hands found Elle’s soft, heavy breasts again and gave them a squeeze.

"Uh... nn..."

"Fine. I’ll start. First we build more intimacy."

"Are you really going to...?"

"Not right away! Just... when the moment feels right."

"What counts as the right moment?"

"When your heart suddenly says ’now.’"

Her own heart ached.

What would Ren say if she told him she had fallen for him the very first day they entered a dungeon together?

Not knowing was torture.

"If I get rejected I might not be able to get out of bed for a week."

"Then I’ll comfort you."

"Really? With those big breasts of yours?"

Watching Elle turn bright red, Aria finally managed a small laugh.

Sharing a crush on the same boy created a strange kind of sisterhood.

It never would have worked if they were guys.

When the person everyone wanted had overwhelming value, real friendship always carried competition underneath. Aria had been quietly looking down on Elle the whole time.

Deep inside she kept thinking, ’I have the advantage over the childhood friend.’ It wasn’t pure meanness just her own cold calculation of their strengths.

She never saw the change coming.

"We decided to start dating," Elle said simply.

"What?"

The world tilted. Aria stared at Ren holding Elle’s hand so naturally, so gently, and felt something inside her crack.

After that her mind went blank. She couldn’t remember a single word she said. She somehow sat through the rest of her classes without absorbing anything.

’She stole him. He’s taken. He’s gone.’
