My Taboo Academy

"Want to nap?"

"Umm... I’m so happy..."

*Nuzzle... nuzzle.*

The cat version of Elle rubbed her cheeks against my chest.

Hugging the sensual black-haired cat I had only seen in photos made something warm swell in my chest.

"Sleep well."

A few hours later I woke up completely refreshed.

Probably thanks to the adorable, voluptuous black-haired cat who had fallen asleep in my arms without a care in the world.

"Hmm... huh..."

She was even drooling a little.

I kissed her forehead gently.

’I have to keep working hard.’

But it was fine to just laze around on a Sunday.

We ended up having intense sex again starting from the afternoon.

Elle was already beautiful with that huge chest, but thanks to her equally busty black-haired mother (who had thoughtfully bought a brand-new box of condoms), the day stayed very busy.

First I fucked the mother like an animal.

Then I had long, tender, loving sessions with Elle.

I finally returned home Monday morning.

"Ren, I ironed your school uniform."

Monday morning. After exploring completely new horizons all weekend.

"Thanks."

Yuna stood in my room looking as flawless as ever.

The perfect honor-student image matched the academy uniform perfectly.

Those enchanting purple eyes curved into a gentle smile.

"Are you okay? Did you sleep enough? Is there anything you need?"

"..."

I had slept, but my cock was still restless.

I wanted Yuna to take care of it.

’Is this a bridge I can cross now?’

I set the freshly ironed uniform aside and quietly unbuckled my belt.

Then I backed her against the wall.

"Oh... Ren...?"

Yuna’s charm always showed most clearly when she was slightly overwhelmed by strength.

Through the half-open door I glimpsed Cleo heading downstairs.

It was almost time to leave for school.

"What if Cleo sees?"

"Use your mouth."

"Ren... did something happen at your girlfriend’s house?"

"I just want to start the day with the feeling of your mouth on my cock."

"..."

She twisted her waist, flustered by the blunt request.

"I can’t help it..."

*Swish.*

Her soft hand wrapped around my already hard cock.

Seeing her kneel in front of me made me let out a long breath.

’I really did it.’

Defeated by lust again.

I had just made my own sister kneel and suck me off right before school.

My conscience was going more numb by the day.

"... you’re being unusually honest today."

Yuna smiled as she stroked me.

"Did you want your sister’s sexual service that badly?"

"At home, you’re the only one I can ask."

"...Alright. Aahh..."

*Slurp...*

She opened her mouth willingly and took my thick cock inside.

I especially liked when she gathered plenty of saliva and made everything wet and slick.

"*Chup... chup... slurp...*"

I patted her head in praise.

Yuna looked up at me with half-lidded eyes, a small smile playing on her lips.

"Since I’m going to honestly accept Yuna’s service from now on..."

"...Mmm... *chup... chup...* okay. I’ll help you, brother."

Her oral technique was pure stimulation.

Through the open door I saw Cleo coming back up the stairs.

’Is she coming here?’

No. She went straight into her own room. Must have forgotten something.

"*Slurp suck suck *"

"Yuna... ugh... the balls too."

Her ears turned bright red.

"... how far are you going to make me go...?"

"You’ve done this before."

I rubbed my balls and the shaft across her pretty face. She looked embarrassed but still accepted it, letting me use her face freely.

"*Kiss... kiss...*"

I shamelessly received soft kisses on my balls from my own sister.

"Ah..."

"You can’t get any on the uniform. Should I wrap it properly with my mouth?"

"Stick your tongue out."

"Okay."

I laid my cock on her flat, saliva-coated tongue and rubbed it slowly. It felt incredible.

If I stopped holding back and truly enjoyed my sister’s mouth...

"You look like you’re really enjoying this."

"I’m going a little deeper."

"Gag... umm... ugh... oh my..."

Yuna...

I pushed the tip against the entrance of her throat and gently rocked.

The way the back of her tongue caressed the sensitive underside of the head was pure heaven.

"Mmm..."

I came straight into her mouth.

*Brrr... brr... brr... brr...!!*

Her cheeks instantly swelled as she struggled to contain the heavy load with that small, pretty face.

"*Gulp... gulp... umph...*"

First thing in the morning I was filling my little sister’s mouth with thick cum.

*Brrr... brrr...!!*

"Um... *gulp... gulp...*"

Cleo’s voice floated in from the hallway.

"Yuna! Ren! Are you coming or not?"

I needed to finish soon or we’d get caught.

*Brrr! Brrr! Brr...!!*

Yuna kept her lips sealed until the very last pulse, swallowing everything.

"Ugh... huff... gasp... huff... *gulp...*"

"Thank you, Yuna."

"Wow... giving your little sister this much before school... did you like it that much?"

I stroked her head and praised her.

"I liked it a lot."

Yuna gave the tip of my cock a few soft kisses and smiled sweetly.

"Stay strong this week, big brother."

Nothing wakes a man up better than a morning blowjob.

The second Monday of Lustbound had officially begun.

The moment I stepped onto academy grounds, Aria called out to me.

"What’s with the complete radio silence all weekend?"

"Something came up. I was busy."

There was no way I could tell her the truth. Especially not Aria.

Whatever she had imagined, the reality had gone far beyond it.

"You didn’t come with Elle? I figured the two of you would arrive together."

"She said she’d come later. Already notified the academy."

"Why? Is she sick?"

Sick wasn’t exactly the right word.

"More like... she used up all her energy."

"Used up...?"

By now it should have been obvious. Elle and I were a couple, and we had spent the entire weekend alone together.

Aria had even assumed we would walk to school side by side, yet she clearly hadn’t considered the physical aftermath of "that kind of activity."

So...

"What are you talking about?"

"She fainted."

"...Fainted?"

Aria looked at me with completely innocent eyes.

Then, reading something in my expression, she slowly lowered her gaze.

"Ah... I see. Something like that..."

Her voice dropped to a near whisper.

"Even fainting...?"

I heard the quiet words.

As a boyfriend, I probably needed to reflect on that.

I didn’t mind continuing to milk every last drop, but I hadn’t realized Elle could actually get dehydrated from it.

"Yeah... something like that."

The atmosphere turned awkward fast.

"How was your weekend?"

"I just stayed home mostly... On Sunday I went to a café with some friends and took pictures at the dance studio. Deleted most of them though. They came out weird."

...Still awkward.

If Aria liked me...

Should I try to meet those expectations somehow?

This was surprisingly hard.

In a normal harem story the protagonist just spoke with confidence and the heroines gathered around him naturally.

Being inside the game made everything more complicated.

Elle had been an easy heroine to win over. Aria was not.

I couldn’t just drag her somewhere, grab her breasts, flash my cock and say,

"Want to be my girlfriend too?" *Wink*

If I tried that, Aria would probably put me in the ground with one clean hit.

I couldn’t confess outright either. I needed to convey three things at once without sounding insane:

1. I already have a beautiful girlfriend.

2. I have zero intention of breaking up with her.

3. Do you still want to be my girlfriend as well?

Why was that so difficult?!

"Sorry for ignoring your messages. As an apology, let me treat you to a meal."

"What?"

Aria’s brows furrowed.

"Hey. Why would you make your own girlfriend unhappy? We can’t just go eat alone together."

’Then what was that weekend invitation about...?’

A normal girl would put up walls, of course.

I didn’t think Aria was the type to take things lightly either.

Any sensible woman would keep distance from a man who already had a girlfriend.

"Then let’s do a dungeon duo today. I’ll help you farm points."

"A man and a woman alone in a dungeon? Who knows what could happen?"

"Aria..."

Was this the end of Ren Asahi’s harem ambitions?

Honestly, having Elle and her mother should already be more than enough.

What kind of greedy lifestyle was I chasing by staring at harems?

’What would a proper protagonist do here?’

Maybe... try holding her hand?

It was already awkward, but I decided to push a little.

"You promised to help me until I hit 10,000 points."

"Did I? Really?"

"How am I supposed to reach 10,000 without you? You said the same thing."

While Aria hesitated, I firmly took her hand.

Tightly.

"What... what are you doing?"

I didn’t let go.

She seemed to decide that forcefully pulling away would look even stranger, so she suddenly went quiet.

Her ears turned red. Her cheeks followed.

I stepped a little closer and spoke calmly.

"How am I supposed to clear the dungeon without Aria’s help?"

"...With Elle... uh? Ah...? You’re too close..."

"Aria..."

I squeezed her hand a little tighter.

"...Ah... no..."

With a sharp tug she pulled free and muttered,

"I’ll go to the dungeon... just don’t do that again."

"..."

Had she always been this cute?

There was a distinct charm to her that was completely different from the raven-haired, heavy-breasted type.

"Aren’t you going to answer? A man who already has a girlfriend grabbing another girl’s hand like that..."

"It would be weird if we suddenly became distant just because Elle and I started dating."
