Ero Academy

Stella approached with a slight blush on her cheeks and pressed her lips to mine.

Sigh ♡

Yesterday, I felt anxious because she kept her distance after hearing my words, but now it seems everything has returned to normal.

"I\'ll help Serena tidy up, and then I\'ll leave."

After Stella departs, Serena and I stand at the entrance of the house.

When I see Serena putting on her school shoes, I recall Enn\'s words.

"Sang-hyuk, you\'re underestimating Serena too much."

Am I underestimating her? What am I missing?

Today, Serena\'s thighs beneath her school uniform skirt are slightly more noticeable. White, translucent skin, incredibly enticing thighs...

These aren\'t her usual exemplary panties?

\'…White knee-high socks…?\'

Serena? But why?

As I ponder this, my eyes meet Serena\'s, who has turned to look back at me.

Serena seems to be in an exceptionally exhilarated state. Is something incredibly thrilling about to unfold?

Her eyes sparkle, as if she is finally welcoming the long-awaited and anticipated moment.

"Big brother."

I flinch, thinking I\'ve been caught sneaking glances at her white stockings.

"Oh, really?"

Serena lifted one side of her skirt herself.

"Today it\'s purple."

Goodness. The panties aren\'t the issue, are they?

Simply by flipping up the skirt, the exposed area of her bare skin increased dramatically, revealing her ample thighs and pubic mound!

"Don\'t you remember? You told me to wear these."

She recalled.

Serena had bought a pair of tiny, risqué thong panties with an extravagant pattern that no student her age should possess.

Holding the strap of the underwear delicately between her fingertips like the fuse of a bomb, she smiled and touched one finger to her cheek.

"Big brother. Are you watching?"

"Uh, uh…"

Watching, indeed…

"What do you think will happen if I let go of this?"

If she lets go, If she lets go, The panties would come off, revealing her vagina, right?

The delicate straps of Serena\'s underwear, which she had gently tugged upwards, now precariously balanced the fate of the garment concealing her womanhood.

"…You. Were you planning to go to the academy like that?"

"Yes! I wanted to cheer you up with a glimpse of my underwear today."

"But aside from me, won\'t the other guys catch a glimpse too?"

Serena squinted her eyes and let a captivating smile spread across her face, as if she couldn\'t help being so enchanting.

"Today, I\'m feeling especially daring, so they might see \'even more than usual.\' My skirt is quite short, and I bought this underwear intending to show it off to you while climbing the stairs, but another guy might accidentally catch sight of it too.

"…"

Could she be encouraging me?

"Relax, sweet brother? My breasts, from head to toe... I don\'t know any other man besides you."

Thump. Thump. Thump.

I approached Serena with my cock standing at attention.

"But if you don\'t claim me... One day, I might marry another man, right? Starting today, if there\'s a man who pursues me... I\'ll consider getting to know him little by little."

"What? You\'re catching on?"

"Well, I\'m not too young or too old to be in a relationship. At home, I\'m your younger sister, but outside, I\'m just a girl who wants to date..."

What kind of trial is this?

Enn once told me. Can a heroine endure being connected to another man?

Why is a heroine even a heroine? Can we accept such a thing as reality?

"Are you going to attract a lot of attention today, right? Wearing such flashy underwear, the top might even be see-through."

… It appears to be see-through.

If you look closely, the underwear definitely stands out. Even if I don\'t like it, I become conscious of Serena\'s breasts.

If her underwear were visible through the gap of the open buttons, the vivid purple would pierce right through to your eyes.

"What if a bunch of guys come and try to hit on me? Oh, I\'m talking about phone numbers.

This girl…

She must have been excited at the thought of teasing her brother with such a lewd script!

"Among so many men, the one person who truly sees my heart and wants to date me purely... Honestly, I\'m not sure if I can tell the difference."

"Serena."

"First and foremost, there\'s no choice but to learn through our bodies while dating, right?"

Serena fastens her underwear strap and turns her back to me. I grab her body from behind as she\'s about to head to school.

"Don\'t go."

"Ah, oppa…"

"Don\'t go to school today."

"Okay, I understand."

I\'m taken aback by her surprisingly obedient response.

"If Oppa says not to go, I won\'t go."

… Ah, I\'ve caught her.

The moment I reveal my true intentions, the mask loses its meaning.

Who\'s the adult here?

Feeling reassured, I rub my dick against Serena\'s ample ass while eagerly massaging her breasts.

This is it!!

"Ah, mmm."

"Serena… Serena…"

"Yes, I know. Ah… These breasts are for Oppa\'s use only. So don\'t worry, okay?"

"Today, don\'t go anywhere."

I grab Serena, who\'s already carrying her bag for school, and take her to my room.

During student days, the world is unbelievably quiet when you slightly exceed your school hours.

On a morning like this, just before being late, with the fresh morning air and sunlight pouring in...

"I give in. Serena… I want to have pregnancy sex with you."

As the older brother spoke of "matters only adults should discuss," he found himself entwined with and rubbing against Serena\'s lush and provocative body.

"Brother, ah…"

Serena smiled, half embarrassed and half delighted, as she surrendered herself to me.

"In truth, I desire you! I yearn to make love to you, Serena! Serena…! I want to release myself inside your womanhood!"

"Alright, I understand. Haa… Brother… I\'ll allow you to impregnate your younger sister\'s most intimate part. Please, calm down.

With a soft rustling sound, Serena\'s bag fell to the floor, spilling textbooks everywhere.

The purple lace panties and bra I had forcibly removed with my hand lay scattered haphazardly atop the mess.

With no panties and no bra beneath her uniform, I pulled Serena onto the bed.

Even as her brother manhandled her, Serena did not resist at all.

Rather, she gracefully lay down, lifting her hips as if to assist.

My breath caught...

Her short skirt could not hide the incredibly ample buttocks now before my very eyes.

I lowered my panties, revealing my erect manhood.

Throughout this, Serena continued to gently sway her hips from side to side.

She moved as if to provoke his angry arousal.

"I\'m sorry I made you feel uncomfortable. Let\'s ease your feelings with my little sister\'s pussy, okay?"

"The nerve of Serena, who\'s been scolded by me before..."

How dare she? How dare she scheme like this with her older brother?

"Do you want to be punished with my hard, bare cock?"

*Slap* *Slap*

As he struck Serena\'s wet, young sister\'s pussy with the head of his cock, she pushed her ass out, not knowing what to do.

"Just like that time... Will you thrust your hard, firm cock into your little sister\'s womb?"

He tightly gripped Serena\'s buttocks.

"That was a mistake. But…"

Grasping Serena\'s ass?

What was he trying to do? Was he planning to shove his erect cock into his sister\'s pussy and take her like a dog?

As he hesitated, removing his hand, Serena gently swayed her hips from side to side.

"Brother! The negative emotions that surged earlier... It\'s not good to hold on to them! Hurry and put your cock in here with me. I\'ll melt them away carefully with my little sister\'s pussy."

"Serena…?"

"Here it is, big brother. Don\'t overthink it; just slide your cock into your little sister\'s pussy and let\'s enjoy ourselves, okay?"

Serena, using one hand to part her buttocks, revealed her moist entrance to me.

Ah.

I immediately pressed my erect dick into Serena\'s inviting hole, bearing my weight on it.

*Swoosh* ♡♡

*Tight grip*… ♡

Covering Serena\'s body with my own, I pushed my throbbing member all the way inside her in one smooth motion.

*Squelch* ♡

"Ah~!"

*Tightening*… *Tightening*…

Once inside and holding still, I could feel Serena\'s pussyfoot adjusting to my cock in real time.

Ever since that first day, my sweet and lovely little sister\'s pussy♡

At last… ♡

What was all that sweet talk yesterday about, huh?

Enn might have already known that my words held no true meaning.

In the end, it comes down to this:

I can\'t stand the thought of giving Serena away to someone else!

"You\'re right on the mark this time, big brother..."
