The Humiliating Penis Dance Flashing Before Her Eyes

But Ha-woon pretended not to know. "W-what is that?"

But Ha-yeon didn't miss his broken, stuttering words and trembling eyes. "I can read your face like an open book, Oppa. You know exactly what it is. There's no way you don't, especially after I explained the posture in such detail."

"B-but... a Penis Dance... I've never heard of a dance with a name like that..."

"Then I'll teach you." She giggled, clearly delighted just by the thought of it. "Push your butt back and say cock♡ Thrust your cock forward and say dance♡ Just keep shaking your hips back and forth while chanting cock♡ cock♡ over and over. See? Simple, right? The Penis Dance."

"Y-you're so vulgar..." Her older brother looked on the verge of tears.

How pretty...♡

Ha-yeon found even this side of him so lovely she felt like she was going crazy. She was glad she had called him to her room. If they had been in his room, the erotic scent would have driven her into heat, and she wouldn't have been able to stop herself from devouring him right then and there♡ Her pussy was already getting a little wet.

"So, are you going to do it or not?"

"I-I can't... Just do what you usually do..." He couldn't even finish his sentence.

"Do what usually, what?"

"...Just take me..."

"How am I supposed to ride a cock that isn't even hard?"

"I-if you just touch it a little... it'll get stiff..."

"Oppa. That's exactly what pisses me off. You asked for time, and I gave it to you. If you've resolved to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠let me use you however I want, shouldn't you be getting hard on your own the moment you see me or smell me? Do you really need your master's hand to do it for you?" Still, she liked that he had begged her to take him on his own♡ Should she give him a chance?

Ha-yeon lifted her hips from her seat, slid her pants and panties down together to strip them off, and crossed her legs, overlapping her thighs. "Ha, fine. If you perform the Penis Dance and get hard, I'll settle for masturbating today while watching you jerk off."

Ha-woon, who had been out of his mind with shame ever since he put on her bra, took the bait without realizing she was testing him. He was already growing to hate his sister even more for forcing this public humiliation on him. It was better to endure this disgrace than to have sex with someone like her.

"Now, dance and make your cock get hard in the dirty way possible. Make it so fucking hot to watch you shake your erect cock that I won't even be able to bring myself to pounce on you because I want to keep watching. Force me to spread my legs and finger my own pussy instead♡"

Ha-woon closed his eyes and pictured Ju-ran. From now on, I'm shaking my hips to please Ju-ran. He slowly pushed his pelvis back, then thrust it forward.

"You have to sing the cock song too. Why is your mouth shut?" Ju-ran would probably love this kind of perverted stuff too. Ju-ran is the one standing in front of me. Pushing his butt back again, he whispered, "Cock..." Thrusting forward, "...ie..."

"Haa... Oppa. Do you think a voice like that is going to make my pussy twitch? Put some more coquettishness into it. Just like when you're getting your cock devoured by me. Before I lose my patience, pounce on you, and make you squeal."

Ju-ran... give me strength...! There was no way Ju-ran would want to give him strength when he was thrusting his cock to satisfy another woman. However, Ha-woon's mind was so consumed by the single-minded desire to avoid sexual intercourse with his sister that he convinced himself achieving this would make him more worthy of Ju-ran.

"Cock...♡ ie...♡"

Ha-yeon didn't say anything. Now I just need to buy some time and get hard by thinking of Ju-ran... He had been worried she might tell him to open his eyes and look at her, so this was a relief. If he had to do that, getting an erection would have been completely out of the question.

Ha-yeon was contemplating. She wanted him to look at her, but watching him perform the Penis Dance with a deeply flushed face, looking as if he were about to cry at any moment, was quite a feast for the eyes. It's a real problem that every single version of him is so delicious.

After tapping her foot for a moment, Ha-yeon decided to leave his expression as it was. "Why don't you snap your pelvis a bit harder?" She wished her brother would open his eyes and look at her with a lewd, ecstatic face, but looking at the state of his limp cock, she doubted she would get that kind of expression out of him right now.

Her older brother moved his hips even more vigorously, just as his sister commanded. "Cock—♡ ie—♡ Cock♡ie♡ Cockie—♡ Cockie♡ Cockie♡ Cockie...♡" His massive cock swayed beautifully with his movements.

"Hehehe... You dirty dog♡ The way your cock dangles around looks just like a puppy wagging its tail because it loves its master♡ It's a beautiful sight. Wagging your little dick-tail for your master."

Unfortunately, Ju-ran did not appear in Ha-woon's mind. It was as if his sister's scent, which filled the room, acted as a powerful shield blocking any intrusion.

"But remember what I said? Get that cock properly hard. Five." Her pussy was twitching so much she couldn't wait any longer, so Ha-yeon began the countdown. "Four." "Cockie♡ Cockie—♡" "Three." "Cock♡ie..." "Two." Ha-woon now accepted that it was over. "One." "..." "Zero."

Ha-yeon spread her legs, revealing her pussy, which glistened faintly with a slight overflow of love juice. "Lick it, you dirty dog."

Resigned to his fate, Ha-woon crawled over to her and knelt. After catching a glimpse of his sister's pussy—a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠sight he knew he shouldn't be looking at—and gauging where his mouth needed to go, Ha-woon closed his eyes.

He knew now. He knew exactly what it felt like when her love juice touched his lips. He even began to think that perhaps it was a relief that he could lick her fountain of aphrodisiac instead of being immediately devoured. If he just let himself go here, he might be able to ignore the disgusting feeling of coupling with this cunning, wicked girl with his already shattered mind.

Even so, he couldn't entirely overcome his resistance to licking his sister's pussy, so he tentatively stuck out his tongue. His sister wasn't about to let that slide. "Mmph—! Ngh..." She grabbed the back of her brother's head and shoved his face directly into her pussy.

"Haa... Why is my Oppa so stupid? Hmm? Did you really think I'd be happy if you just shook your cock around because I said I'd let you off with jerking off? Huh? Did you think I'd like that? If I gave you time, you should have realized your place, thrust your hard cock at me, and begged me to let you put it in, you fucking piece of shit."

She stroked his cock with her foot. She could feel it twitching and swelling. "Haa... Look at your cock getting hard just from licking my pussy♡ Do you like it? Do you? Do you like your little sister's pussy that much?"

She pulled Ha-woon back by his hair, forcing him to look at her face. She directed a gaze at him that was so burning with lust it felt as if it would incinerate him. "Yes... I like it... I love it♡" Ha-woon completely let go of his sanity. He knew he would writhe in self-loathing once he came to his senses, but he had no choice but to ignore the immediate future. "Now you're talking, you motherfucker♡" He had to do this, if only to catch her off guard.

Listening to the siblings' conversation through her headphones, Seo-hye's heart sank. Her already trembling hands clenched into tight fists. Red blood began to drip from between the cracks of her brutally crumpled notebook.

When she had heard Ha-woon say that she could do whatever she wanted with his body, she had assumed he meant something like letting her run errands or order him around.

At first, she doubted her own ears. But as it went on, the siblings' conversation crossed all boundaries. It was so filthy and disgusting that she wanted to rip the headphones off and throw them away, but then she remembered her purpose. Even though Ha-woon wasn't actively resisting, he clearly seemed to be dragged along against his will. Maybe... he needs my help.

He was filthy. He was contemptible. Seo-hye admitted to herself that her feelings for him had already cooled to ice. But why, then, could she not just abandon him like this?

Seo-hye quickly gathered her chaotic thoughts. He was a man she had liked, if only for a brief moment. He was the first man to ever make her heart flutter like that. It was only natural that she couldn't just ignore the plight of such a person.

To think she hid such a low, vulgar nature behind a pretty face that looks so much like Ha-woon's. She felt a deep, burning rage toward Ha-yeon for forcing her older brother into such a humiliating posture. "How dare she... how dare she..." The thoughts in her head slipped out of her mouth before she even realized it.

Her heart pounded, thumping violently against her chest. A natural physical response to escalating emotions—that was the diagnosis Seo-hye gave herself, but she remained blissfully unaware. Unaware that the depths of her groin were slowly beginning to slick over. Unaware of the pitch-black abyss inside her that she herself had yet to recognize—a dark desire to force Ha-woon to wear her own underwear. A fierce, burning jealousy toward Ha-yeon for playing with Ha-woon however she pleased.

The image of Ha-woon shaking his hips while chanting cock, cock in that vulgar manner flashed before her eyes. Seo-hye clutched her head and shook ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it violently. "I don't want to see it... I don't want to see it..." I'm only enduring this and listening to save him.

The agonizing time ended with Ha-yeon's countdown. Although something even more disastrous was bound to happen next, Seo-hye felt an unbearable pity for Ha-woon. How could a younger sister command her older brother to lick her private parts with such absolute, shameless authority?

But then,

Ha-woon's attitude had done a complete 180-degree turn ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠in an instant. Her heart, which had been burning hot enough to incinerate her entire body, felt as if it had frozen solid in a split second. Unaware that her fingernails were digging deep into her clenched fists, drawing blood, Seo-hye muttered like a madwoman. "You... Seong Ha-woon, you..."

Filthy sounds filled both of her ears.

The sound of him sucking on that wet flesh so greedily was unbelievable, completely uncharacteristic of the man she thought she knew.

Feeling utterly ridiculous for wanting to save Ha-woon just moments ago, her sense of betrayal toward him amplified massively. A filthy human being who gets off on licking his own sister's crotch had the nerve to act all hypocritical in front of me?

But what drove her even crazier was the fact that, despite all of this, her desire to possess him only grew stronger. The seeds of sadism were beginning to sprout.
