Beloved Sisters
Riiip!
"Aaaaargh—!!!"
Tang Hwi's shaft tore through her tight, unaroused maidenhood without a single stroke of foreplay. Ever since his Metamorphosis, his manhood had grown into a monstrous weapon, measuring nearly a foot when fully erect. It was a size and thickness that would have been overwhelming even if she were dripping wet, yet he had brutally forced his way into a completely dry virgin. Though martial artists train to endure physical torment, Tang Ga-in could not help but shriek at the raw, agonizing sensation of her flesh tearing apart. As she thrashed and wept like a fish impaled on a harpoon, Tang Hwi felt a deep sense of satisfaction swell within him.
My dear sister, I'm sorry. I'll make it up to you later, so just bear with it for now.
Harboring a thought so absurd that she would have sworn eternal vengeance had she heard it, Tang Hwi outwardly continued to act like a mindless beast.
"Graaaah!"
"It hurts! Brother, it hurts...! Ah, ugh!"
"Raaah!"
Pretending not to hear her, he ruthlessly impaled Tang Ga-in's core. His monstrous shaft began to rapidly plunge in and out of her tight, virginal walls.
Squelch! Squelch! Squelch! Squelch!
"Aaaah! Stop...! Sto-o-op...!!"
Tang Ga-in writhed in unbearable agony. She screamed at the top of her lungs and struggled to break free, but the more she resisted, the harder Tang Hwi pinned her down with his entire body. It was as if he was asserting that rebellion was utterly futile. Tears poured from her eyes in an endless stream of pain and sorrow. What had she done to deserve this? Why was Tang Hwi, her own brother, raping her? The sheer sorrow of having her purity defiled by her own flesh and blood right after their duel crushed her spirit. Yet, despite his brutal actions, his face looked as if he were the one in agony...
Wait, what is wrong with Brother's face...?
Even as she shrieked from the relentless, agonizing thrusts that gave her torn hymen no time to heal, Tang Ga-in's sharp mind began to analyze the man pinning her down. If he were merely a lust-crazed fool committing a rape, he would have ripped her clothes to shreds, groped her breasts, and greedily devoured her lips. But Tang Hwi was different. He acted as if he only craved her lower half, pinning her limbs so she couldn't resist while mindlessly thrusting his hips like a wild animal. He wasn't using any of the bedroom arts he had been taught from a young age to avoid bringing shame to the direct line; he was driven purely by raw instinct. And his face... it was twisted with guilt and torment, as if he barely even realized he was violating her. The swollen, pulsing veins on his forehead looked exactly like those of a martial artist suffering from Qi Deviation due to a failed energy circulation.
"Aaaah! It hurts...!"
Even as she screamed, Tang Ga-in's brilliant mind desperately searched for a reason. A reason why her own brother, Tang Hwi, had no choice but to assault her. Being a fundamentally kind-hearted woman, she was trying her best not to blame her own flesh and blood, even while being stripped of her virginity. She remained completely oblivious to the fact that Tang Hwi was exploiting this very nature of hers to orchestrate the entire assault.
Squish! Squish! Squish!
"Ah...!"
The tone of her voice changed.
Squish! Squish! Squish! Squish!
"Ngh! Ah... Ah, it hurts!!"
The pain was still very real. However, while the sensation had been entirely painful moments ago, it had now lessened slightly. Her body was beginning to process a fraction of it as pleasure. As his massive shaft continued to hammer into her, her body reacted to alleviate the friction, secreting natural lubrication and shifting her physical response.
"Damn it! Damn it all!"
"Ugh... Brother?"
"Every single one of them...! They all look down on me!"
"..."
Staring into his bloodshot eyes, Tang Ga-in forgot to scream. He looked so utterly devastated that broken capillaries in his eyes wept tears of blood. As if crying out against a world that had done nothing but torment him, Tang Hwi roared like a man completely consumed by Qi Deviation.
"Do you think I didn't try?! I trained in poison arts until I spat black blood! I pushed my fingers to the bone!"
His cry was filled with raw, desperate resentment.
Well, it's not a lie. That's why she'll be even more confused.
Before awakening his memories of his past lives, he truly had struggled and grown twisted in his efforts. That was why his acting was so incredibly convincing—it was rooted in emotions he had once genuinely felt.
"And yet, those old bastards who look down on me cherish you so much! Even though I can pin you down like this! Even though I can trample you...!"
"...Ngh. Ah."
Hearing her brother's grief-stricken cry, Tang Ga-in's resistance crumbled. Instead of trying to escape, she wrapped her arms around Tang Hwi as if to comfort him. She held him tight, silently enduring the pain.
Squish! Squish! Squish! Squish!
"Ngh."
Her inner walls burned as if scorched by fire. It was hot and agonizingly sore. Yet, Tang Ga-in gritted her teeth, holding Tang Hwi and letting him have his way. She had no idea he was suffering this much. No, she had known he was struggling, but she hadn't realized it ran this deep. As his sister, she had been too indifferent, too careless. Perhaps her constant teasing, calling him useless, had finally caused his pent-up resentment to explode. She even found herself thinking that it was a relief Tang Hwi had targeted her instead of anyone else. If it had been their mother, Tang Suryeon, she would have ruthlessly destroyed his Danjeon. If it had been Tang Ga-hui, her heart would have shattered from the betrayal.
I just need to endure it. Just this once... if I can just get through this.
She still remembered how happy their family had been when they were young. Namgung Bu-ryun had always been cold, but the others weren't. Tang Suryeon, though strict, had cared deeply for her children. Tang Ga-hui had been bright and kind to her siblings. And Tang Hwi, when he first started learning martial arts, had been an innocent, carefree brother who doted on his little sister. These memories flashed through her mind like a fleeting dream. For the sake of those precious memories, Tang Ga-in did not want her family to fall apart any further. If she just endured this, Tang Hwi would calm down, and there would still be a chance for their family to return to how they used to be.
"I'm cumming!"
"...What?"
While she was desperately enduring the burning soreness inside her, Tang Hwi suddenly shouted in a strained voice. For a split second, she didn't register his words, but her sharp mind quickly deciphered what her brother meant despite the pain. She belatedly began to thrash, trying to push Tang Hwi away.
"N-no! Not inside...!"
But it was already too late.
Spurt! Splurt! Shooot! Squelch.
"Ah... Ahhh...!"
Despair filled Tang Ga-in's eyes. No matter how determined she was to bear her brother's twisted Heart Demon, she had never bargained for the risk of carrying his child. She had to get the semen out of her body immediately. Terrified that she might actually get pregnant, she tried to pull away from him.
"I-I have to get it out...! Ah!"
Squish.
Her attempt was instantly thwarted as his still rock-hard shaft thrust deep into her flesh once more.
"Why... why is it still hard?!"
From her basic education, Tang Ga-in knew that a man's erection was supposed to subside after ejaculation, requiring time to recover. What she didn't know, however, was that Tang Hwi's body had been refined into the ultimate physical vessel through his Metamorphosis. Furthermore, among the countless martial arts he had mastered across his many past lives, there were several esoteric sexual arts that could easily be classified as divine techniques. He had synthesized them all into a single, unified discipline: the Yin-Yang Erotic Art.
An esoteric technique that converts internal energy directly into sexual stamina. When semen infused with the practitioner's internal energy is released inside a woman, it physically conditions her to crave his touch. As the male energy settles in her Danjeon, she is subconsciously driven to desire him. Once she accepts these feelings, the male energy harmonizes with her own internal energy, creating a perfect balance of Yin and Yang that dramatically amplifies her cultivation.
I originally planned to use this to conquer Sister Ga-hui first. Since the order got mixed up, I guess I'll make an example out of Ga-in first.
Having made up his mind, Tang Hwi began to swing his hips once more.
Squish. Squish. Squish. Squish.
"Ugh! Ah...!"
Tears welled in Tang Ga-in's eyes. Being violated again after having him ejaculate inside her made it impossible to suppress her overwhelming sorrow. Though her grief manifested physically, Tang Hwi did not stop. Instead, he began to actively circulate his Yin-Yang Erotic Art, ensuring Tang Ga-in would feel the full force of the technique.
"Ah! Oh, ahhh...! What is this? I don't... understand...! Ahhh!"
As her sensitivity amplified, Tang Ga-in began to experience an unexpected rush of intense pleasure, letting out breathless moans. Confused as to why she was feeling pleasure while being violated, she couldn't even think to hide her panic. In intimacy, mindset is everything. No matter how impressive a man's member is, coupling with an ugly man will instantly cool any affection, turning the act from lovemaking into physical trauma. There is a reason why sexual predators are classified as demons in the Jianghu; even though they are merely unorthodox martial artists who assault women, they leave deep, irreversible psychological scars. Yet, after being filled to the brim by Tang Hwi, a thrilling wave of ecstasy began to wash over her.
"Ah! Oh?! Why... why is this happening...?"
She'll start to believe she's just naturally depraved.
Squish. Squish. Squish. Squish.
"Ahhh...! Oh!"
Tang Ga-in was utterly lost in confusion.
