My Taboo Academy

"Excuses? You’ve got a girlfriend and you’re still rubbing yourself all over another woman’s thighs."

"...Can’t we call it ’giving her my heart’?"

"I don’t use soft language like that."

"You’re supposed to be an intelligent being. Have some shame."

Mira put her hands on her hips and sighed.

"If you keep dodging like this, the number of unhappy heroines is just going to grow."

"...I haven’t done anything that strange."

"You’re already making one of them sad!"

She meant Aria, didn’t she?

"No... If anyone would be sad about cheating, it’s Elle."

"You still don’t get it. A harem isn’t that simple."

I could feel the lecture coming.

A blackboard rose out of the floor. Mira slipped on a pair of glasses.

"Look carefully."

"Your entire approach is wrong right now."

"..."

"...Mira, how old are you again?"

In one smooth motion the blackboard and glasses vanished.

"Ahem! Anyway! If you have two lovers, it’s a disaster, right?"

"Obviously."

"What about three? Four?"

"Does the guy have zero conscience?"

"No!! The women start competing for the male’s love. From that point on, cheating stops being a problem! It’s only natural that the man does that!"

"Where do you get that kind of confidence?"

"This is the life of a dominant male! I’m explaining it because you, Ren, still don’t understand!"

No dominant male in modern society lived with dozens of women.

To me her twisted philosophy just sounded like the standard Lustbound protagonist who mindlessly fucked everything that moved.

"So it’s fine if Aria goes out with other guys?"

"Stop putting horrible images in my head."

Of course I hated the idea.

The lingering feelings from our earlier flirting hadn’t disappeared. I still liked Aria. Now that I had a girlfriend I was deliberately keeping my distance.

"This is basic Lustbound knowledge. Cheating isn’t an issue. Just try it."

"It is an issue. Do you want me to get stabbed to death?"

"You have to give love properly. That’s why."

Wait... was she saying I’d get stabbed if I *didn’t*?

Chilling.

"I don’t know if I’ll marry Elle or not. Right now we’re still getting to know each other.

Maybe we’ll date with marriage in mind.

In a year or two, once I’m more established,

I’ll take out a loan and buy a house. If Fleshlight sales go well I might not even need the loan. Find a place big enough for the family and start building a life together from there"

Huh. This "life plan" felt weirdly familiar.

I’d been riding this exact boring path even before I got possessed.

"I’ve lived as a normal guy for so long that all my harem cells are dead."

"Today you’ll realize the protagonist doesn’t have to look for happiness so far in the future."

...It sounded like a prophecy from a shady fortune-teller.

"Mira, I understand what you’re saying. But am I supposed to just change overnight?"

I’d lived more than twenty years in the normal world.

Suddenly turning into a man who consumed every woman in sight just because I got isekai’d would be weirder.

"First step: unlock the door. Learn to treat taking care of your sister’s morning needs as natural. That’s what a real man does."

...What exactly did Mira think a real man was?

After she finally left, the fourth morning in Lustbound officially began.

"Ugh."

The erection refused to go down. My lower back already ached.

My cock was basically screaming, "Where’s Yuna’s mouth? Give it back!"

’It’s the weekend...’

Maybe I should just sleep more.

A message arrived at that exact moment.

[Elle]

When are you coming over today?

Right. I was supposed to visit Elle’s place.

[Ren Asahi]

After breakfast. Send me the address.

Yesterday’s cat cosplay photo of Elle... yeah, that had been great.

The thought of seeing my girlfriend made a little excitement bubble up.

"Brother, you awake?"

I ran into Cleo on the stairs.

"Morning, Cleo."

"..."

Her eyes dropped straight to the obvious bulge in my pants. She immediately hurried down the rest of the stairs.

"It’s just a physiological reaction!"

The erection still didn’t go down.

Yuna, who was already preparing breakfast, took one look and started laughing.

’Why is she laughing?’

"... if it’s too hard, I can help."

"No. It’ll go down soon."

That’s what I said.

But with both Yuna and Cleo in the same house, there was zero chance of it calming down. I stayed fully hard the entire morning.

"Bread for breakfast?"

The surface was golden and buttery. The girls seemed fine with just yogurt and bananas.

"You’re not eating?"

"Diet."

Cleo finished quickly and stood up. Her pink shorts were impossible to ignore.

"What are you staring at, big brother?"

"Nothing."

I said it fast, trying not to get caught looking at her ass.

I expected her to tell me to look away. Instead Cleo casually tugged the waistband of her shorts down right in front of me.

Almost like a wink.

"Beige."

For a split second I thought she wasn’t wearing anything underneath.

...

"Why so surprised when you were the one staring?"

"...Nice."

"Don’t do that outside. Just do it with us."

"Just do it with us."

Was she talking about the underwear? There was no way she knew what Yuna and I had been doing. If she did, red lightning would already be flying.

Cleo went back upstairs with a sly little smile.

’...Beige...’

The secret inside her shorts.

Damn it. The erection still wouldn’t go down.

"I’m about to do laundry. If you have anything that needs washing, bring it over."

’Laundry... why does that sound so suggestive when she says it?’

Imagination. It had to be imagination.

The first weekend in Lustbound with both sisters home was already dangerous before breakfast was even over.

I went to the laundry room to drop off my school uniform. Yuna was standing with her back to me, pulling clothes out of the dryer.

...

*Sway.*

Those full, soft cheeks shifted gently with every movement.

"Ah, You’re here. Just put it in the basket."

She meant the laundry basket... right?

" Hurry up and put it in."

I gave her ass a firm slap.

"Eek!!?"

"Stop teasing."

"Sorry..."

She didn’t look sorry at all.

Her eyes sparkled with pure mischief, like she was thinking, "Too bad, I didn’t get to tease you more" .

Standing there with the laundry basket in her arms she somehow still looked completely pure and refreshing.

" where are you going?"

"To see my girlfriend. I might be late, so don’t wait up."

"Mm... your girlfriend is in for a surprise."

...What was that supposed to mean?

"Ren, you’re amazing."

"...How did you find out?"

"Like this"

"Stop. Don’t say another word. How do we even end this conversation?"

I left the house already exhausted.

Paradoxically, the exhaustion came from having *too much* stamina.

Out on the street with no heroines around, my stubborn cock finally started to calm down, little by little.

...

The closer I got to the new villa where my black-haired, K-cup girlfriend was waiting, the harder my blood started pumping again.

"We’ve only been dating since yesterday. Is it shameless to already be hoping for... that?"

Still, it would be a lie to say I wasn’t hoping for something while heading to my girlfriend’s place on the weekend.

[Elle]

Entrance code is 1013.

1013...

Room 305. This should be it.

"Huh?"

It wasn’t a gravitational anomaly, but something strange on the floor in front of the door caught my eye. Words had been carved into the surface, complete with a familiar star symbol.

[Perverted sex lies ahead.]

[Author: Mira, the transcendentally beautiful goddess]

[Oh, two perverted holes]

[Author: Cute and adorable Mira]

...

Sex with my girlfriend was allowed.

If I got too worked up I’d just fall into Mira’s trap. Stay calm and go in properly.

I pressed the doorbell.

My patience was already at its limit. The second I saw Elle’s face I was ready to pull her into a hug.

Hurry up and show me that pretty face

"Yes, who is it?"

The person who opened the door was...

"Oh my."

Not Elle.

"A friend of my daughter? And a boy, no less?"

It was her mother.

I almost pulled her into a hug on pure instinct, mistaking her for Elle.

Why the hell did I assume the house would be empty? I lived with family too!

Meeting my girlfriend’s parent without warning made cold sweat break out instantly.

"This is Elle’s friend, Ren Asahi."

"Yes, I’ve heard a little about you. Come in, come in."

The moment I stepped past the entrance, glowing text flared across the wall.

[This MILF will keep you hooked.]

Thankfully neither mother nor daughter seemed able to see the goddess’s filthy message.

When I bent down to take off my shoes another line appeared on the floor.

[Ahead, erections prove effective.]

’Just stay calm.’

These were Elle’s parents. Dirty thoughts had no place here.

Right?

’No matter how I look at her, she doesn’t look like a mother who already has a grown daughter.’

They clearly resembled each other, but there was no way she was a stepmother.

It was probably rude to think it, yet Elle’s mother looked like the perfected future version of Elle herself.

The sensuality rolling off her was overwhelming.

A beige dress clung to every curve in that classic "missy" style.

The slim midriff made it obvious where Elle’s chest genes had come from.

The deep valley between those breasts was impossible to ignore.

Beautiful face, gentle smile she looked no older than her late twenties no matter the angle.
