ERO ACADEMY

It's morning.
I cannot feel the moist and rough touch of the tongue as it grazes my erect penis, nor the delicate fingers wrapping around my balls.
An ordinary morning.
This should certainly be normal, yet I'm left with a lingering sense of longing.

My cock, unable to forget Serena's devoted oral service, trembles as it stands erect, pointing to the ceiling.

"Idiot. Fool."
"Surprise!"

I'm startled as a blonde figure emerges beside the bed!
I was sure the door was locked!
The intruder turns out to be Enn, the goddess of Yagem.

"Enn… You scared me."
"I'm the one who's surprised, Sang-hyuk! To think that the protagonist of Yagem wrapped his dick in tissue twice...
"Uh…"

I hastily throw the wad of tissues rolling across the table into the trash can.

"Stupid fool."
"Can you stop belittling my efforts to maintain peace in the household?"
"Why do you use tissues when you have a good Onahole called your sister? Are you dense?"
"My little sister is not an onahole!"

Don't force distorted logic upon me.
I'm already feeling confused these days!

"If I had asked for Serena's help, I could have slept with my mouth filled and felt so good~."
"No… Is Serena some sort of personal onahole for me?"
"Isn't she?"
"What if Stella were to find out?"
"Then you'd have two onaholes! Hehe~!"

Would it really end up like that?

"Stella is vulnerable to being violated! You've appealed to her countless times. If you were to pounce on her, saying, 'I can't help it; I'm sorry that I desired Stella,' then afterwards..."
"I don't do that; I won't. Haven't you seen me put all my assets into buying sanitary pads?"
"You pure love lunatic!!"
"I am simply normal."

In fact, the unstable relationship between Serena and me is unbearable right now.
Stella is the innocent younger sister who has just begun to regain her trust in her older brother.

Erotic acts have no place here.

"What if Stella saw me doing that with Serena? How shocked she would be!"

It would be 100% Dark Stella all over again.

That's when it happens. "Can I use my little sister's hole?! Just right!" "I trusted you, big brother; I trusted you!" she cries out♡.

This perverse goddess. Stella's impersonations are so convincing that she draws even more attention.

"Don't just scold me; acknowledge what I've done well. I'm trying to play along with the 'OnaAka' rules."
"Ah!"

En blushes and laughs happily.

"It was amazing... The expression on Isabella's face, the secretive heroine of OnaAka, collapsing helplessly due to her own desires...
"That's a lot of progress, right? You admit it?"
"Well, I didn't give you unlimited energy for no reason. You should have put your cock in my pussycat and said, 'I'll stamp it for every thrust you take inside me♡'."
"What on earth is going on in your head?!"

Wait, is she talking about unlimited energy right now?
No wonder I was in trouble because my cock stayed hard no matter how many times we did it.
That's not a complaint, though. Any man would know. Endless energy is a blessing.

"Even so, I enjoyed your uterine massage play during the erotic game, Sang-hyuk, so I'll grant you one point of recognition."

[I received Enn's approval!]
[Approval +1]

"… I'm not exactly thrilled, but...
"I was holding my breath and patiently waiting until Isabella squirted jelly."
"Do you really think I would do such a thing?"
"I saw you cheating with Seridwen even though you have a girlfriend~?"

When did that happen again?

"Ah, the pure love enthusiast Kim Sang-hyuk is no more."
"It's because I keep getting overly stimulating appeals from the erotic game."

Nonsensical situations keep occurring. From the beginning!

"Eh~ Are you making excuses? While you have a girlfriend, you're rubbing your juices on the thighs of a dark-haired, older hunter."
"... Can't I express it as 'I gave her my heart'?"
"I don't use words like that."
"As an intelligent being, shouldn't you have some sense of shame?"

Enn placed her hand on her waist and sighed.

"If you keep evading like that, will the number of unhappy heroines increase?"
"...Not particularly. I didn't do anything strange."

"You're already making a woman sad!"

Who is she talking about, Yuuna?

"No… On the contrary, Henna would be sad if I cheated on her."
"You really don't understand~ A harem isn't that simple."

I have a hunch that Enn's harem lesson is about to begin.
A blackboard emerges from the floor, and Enn puts on her glasses.

"Now, look."
"Your approach is completely off right now."
"...."
"By any chance... Enn, how old are you?"

With a smooth motion,
The blackboard and glasses vanish.

"Ah, ahem. Now! If you have two women as lovers, it would lead to a disaster, right?"
"I suppose so."
"What about three? Or four?"
"Does the man have no conscience?"
"No!! The women start competing for the love of the alpha male. From then on, cheating is no longer an issue! It's natural for my man to do that!"
"Where do you get such confidence?"
"This! It's the life of a dominant male! I'm telling you because you, Sang-hyuk, don't know!"

A dominant male wouldn't live with dozens of women in today's society.
In my eyes, her twisted philosophy was nothing more than that of a "Yagem protagonist" who repeatedly indulges in reckless, carnal encounters.

"Is it okay for Yuuna to meet other men?"
"Stop making me imagine such messed-up scenarios."

Of course, I don't like it.
It's not as if the traces of our flirtation suddenly vanished; I still harbor feelings for Yuuna. Now that I have a girlfriend, I'm doing my best to avoid getting too close to her.

"This is a review. It's common sense you should know when playing 'OnaAka.' Cheating is not an issue. Give it a try."
"It can't be a non-issue... Do you want to see me get stabbed and die?"
"You have to give love properly. That's why."

Wait… Are you saying that if I don't, I might get stabbed?
That's just chilling.

"I don't know if I'll marry Henna or not. But for now, we have time to get to know each other better.

Perhaps we can date with the prospect of marriage in mind.

In a year or two from now, once I'm more established in society,

I should get a loan and buy a house first. If the sales of Onaholes go well, I might not even need a loan. Finding a spacious house for my family to live in and starting to work together from there

Huh? This "Life Rail" feels strangely familiar.
Now that I think about it, I had been riding this weary path even before I was possessed.

"Pitifully, I've lived as a Villagemian for so long. My harem cells are all dead."
"Where do those cells even exist?"
"You, Sang-hyuk, will come to realize today that the protagonist doesn't have to look for a happy future so far away."

… It's like a prophecy from a pseudo-shaman.

"En, I understand what you're saying. Will I suddenly change?"

I've lived in the village world for over 20 years.
Wouldn't it be strange if I suddenly devoured everything just because I was possessed?

"First of all, open the locked door. You should learn to accept taking care of your sister's morning arousal as if it's natural. A true man."

… What does En think a real man is?

Anyway, the fourth morning since being possessed by "OnaAka" began after she left.

"Ugh."

My erection won't subside, and my back aches from it.
My cock seems to be protesting, demanding, "Where's Serena's mouth? Give it to me!"

'Today's the weekend...'

Should I sleep more?
Just as I thought about it, a message came.

[Henna]
When are you coming to my house today?

Ah… I was supposed to go to Henna's house.

[Kim Sang-hyuk]
I'll go after breakfast. Please send me the address.

The cosplay, Henna I saw yesterday... It was great.
I felt a little excited at the thought of going to see my girlfriend.

"Brother, are you awake?"

I run into Stella on the stairs.

"Hello, Stella."
"…"

Stella's eyes meet my bulging erection over my pants, and she hurriedly descends the stairs.

"Bird, it's a physiological phenomenon!"

My erection doesn't subside.
Serena, who was preparing breakfast, chuckled upon seeing my erect cock.

'Why is she laughing like that?'

"Oppa… If it's hard for you, I can."
"No, it will go down soon."

That's what I said, but

Seeing Serena and Stella, there was no way to restrain his hardened arousal, and he remained in a state of full erection all morning.

"Is bread on the breakfast menu?"

The surface, cooked to a golden-brown with butter, looked appetizing. The younger sisters seemed to be content with yogurt and bananas.

"Aren't you eating any?"
"We're on a diet."

Stella replied coolly, finished her meal, and stood up. Her hot pink dolphin shorts were eye-catching.

"What are you looking at, big brother?"
"Oh, nothing?"

He said it, not wanting to be caught admiring Stella's rear.
He assumed she would tell him to look away anyway. However, Stella pulled down her shorts right in front of him.
As if winking.

"Beige."

For a moment, he thought she wasn't wearing any pants.
…

"Why were you surprised when you asked, big brother?"
"…Nice."
"Don't do that outside. Just do it with us."

"Just do it with us."
Is she talking about the pants? There's no way she could know what Serena and I have been doing. If she did, a bright red punishment would have struck me without hesitation.

Stella ascends the stairs with a sly expression on her face.

'…beige…'

The secret within the blonde tsundere sister's dolphin pants
Ah, damn it... The erection just won't cease.

"Oppa, I'm about to do laundry, so if you have any clothes to wash, I'll take care of them for you. Just bring them over."

'Washing… Why is she making that part sound so suggestive?'

Is it just my imagination? It must be, right?
The first weekend in "OnaAka," when both younger sisters were at home together, was rather perilous from the very morning.
As I entered the changing room to place my school uniform in the laundry basket, Serena, with her rear facing me, was taking clothes out of the dryer.

…
Swaying.
Serena's ample buttocks quivered gently.

"Ah, Oppa, are you here? I'll wash it for you. Just put it in there."

That's about the laundry basket, right?

"Oh~ppa? Hurry up and put it in."

I slapped Serena on the hip.

"Eek!!?"
"Quit fooling around."
"I'm sorry…"

She doesn't seem genuinely apologetic, does she?
Her eyes twinkled with a mischievous grin as if to say, 'Too bad, Oppa, I couldn't tease you more♡.'

On such a topic, her appearance standing with a laundry basket in her arms is utterly innocent and refreshing.

"Oppa, where are you going?"
"To see my girlfriend. I might be late, so don't wait for me."
"Um, your girlfriend is in for a surprise."

… What's the big deal?

"Oppa, you're incredible."
"… How did you find out?"
"Like this~♡"
"Wait. Don't say anymore. How do we end this conversation?"

I'm already exhausted as I leave the house.
Paradoxically, I'm tired because my stamina is endless.
My cock, which didn't know how to shrink, came out to the street without any heroines and cooled down little by little.

…
As I got closer to the newly built villa where my black-haired K-cup girlfriend was waiting for me, my blood surged.

"Since we started dating yesterday, is it shameless to expect that much?"

Still, it would be a lie to say I wasn't hoping for something like that while heading to my girlfriend's house for the weekend.

[Henna]
The entrance code is 1013.

1013…
Room 305? Is this it?

"Huh?"

It wasn't an abnormal gravitational wave, but a peculiar undulation caught the eye on the floor in front of room 305, prompting a closer inspection. Carved into the floor were words, accompanied by a familiar star symbol.

[Perverted sex lies ahead.]
[Author: Enn★, the transcendentally beautiful goddess]

[Oh, two perverted holes]
[Author: Cute and adorable Enn★]

…

Having sex with one's girlfriend is possible.
If I get agitated, I'll fall into Enn's trap. I should maintain my composure and proceed.

Upon pressing the doorbell, the door opens.

Patience has reached its limit. The moment I saw Henna's face, I felt the urge to embrace her.
Hurry up and show me your beautiful face, Henna.

"Yes, who is it~?"

However, the person who emerged from the opened door was...

"Oh my goodness?"

Henna's older sister.

"A friend of my daughter? A boy, huh?"

No, it was the mother.
