The Wrong Passage
Each part of Lua's body served its own purpose in the morning. And among them were those involved in a person's pleasure. The place where Lua—having completely lost her mind—had thrust her cock was one such spot. However, it was not a place that felt pleasure from having something inserted, but from expelling something.
Consumed by the curse and no longer in her right mind, Lua had grown impatient after several failed attempts at penetration. Her aim had gone awry, and she ended up forcing her massive member into the wrong place entirely. It was her older brother's anus.
The Grand Duke herself remained utterly unaware that anything was wrong.
“Ah……♥ Brother’s pussy♥ It’s so tight it won’t go in…? Should I give it a little time to adjust? Hehe……♥”
“Lu-Lua…… Th-that’s…… ngh……♡”
Sia wanted to beg her to pull out, but the words refused to form. The searing pain and overwhelming sense of intrusion from having something forcibly shoved into his ass—especially something as grotesquely oversized as the Grand Duke’s enormous cock—left him capable of nothing but desperate panting.
“Ah, ugh……♡”
Sia, his entire body drenched in sweat, trembled as he looked up at Lua. Since speech had failed him, he tried to convey his wishes through his eyes alone.
“Brother……♥ Does it hurt……?”
“Agh……♡ Hngh……♡”
Golden eyes clouded with agony. Damp strands of hair clung to his cheeks, one of them caught between his lips.
“Brother looks most beautiful when he’s suffering like this……♥”
Yet Sia’s desperate gaze only amplified the Grand Duke’s urges. Lua’s eyes and lips curved into an even more wicked smile.
Why… why doesn’t she realize she put it in the wrong place……?
As that thought crossed his mind, Sia’s eyes fell on Lua’s explosively large breasts. Every time the Grand Duke took a rapturous breath, those heavy mounds rose and fell. Could that be why she couldn’t see what was happening down below?
“Mmmh♥ Brother’s insides keep wriggling and squeezing… I can’t hold back anymore……♥”
“Hngh……?”
“I-I’m gonna cum right now… Ohhooooh?!♥”
The corrupting pleasure surges. Reason dissolves. The body betrays the mind.
Spluuuurrrrrt!
“Hngh?!♡”
Joy flooded Lua’s face for a brief moment before her climax suddenly overtook her. Sia felt something scalding hot flood his belly like molten lava. The overwhelming revulsion nearly broke him. He curled his toes as tightly as possible, fingers clawing at the bedsheets in a desperate attempt to endure.
“Ahk…… Aahk……?!♡”
A flicker of confusion appeared in Sia’s golden eyes. Only moments ago the pain had felt unbearable, like it would kill him—yet now it was gone. No, more than that. He was beginning to feel pleasure from the way her enormous cock crushed his internal organs.
Spluuuurrrrrt!
“Ohooh♥ Haa……♥ Doesn’t it feel good for you too, Brother? Your insides are clenching around my cock like you want more♥”
“Haaahk……!♡”
Setting aside the fact that Lua still mistakenly believed she was inside his pussy, Sia was horrified by the ecstasy he was feeling. Every spurt of hot semen made his lower belly tingle. He couldn’t understand why his body was reacting this way.
“Huu……♥ Brother…… I think you’ve adjusted enough now. Shall I start moving?♥”
“W-wait? N-no……♡”
Sia desperately tried to tell her no, but his tongue tangled and his words came out slurred.
“You just came and you want to keep going? Of course. You know one round isn’t enough for me♥”
“Th-that’s not wha—”
Plap!
“Ahk?!♡”
The mere snap of Lua’s hips was enough to make Sia feel as if his brain had been shaken.
“Khh……♥”
The Grand Duke licked her lips as if savoring a delicious meal, catching the drool that had nearly spilled.
No… if I keep letting her do this, I’ll… I’ll break……♡
Sia instinctively understood. If he allowed her to keep cumming inside him, something irreversible would happen. He reached forward, trying to grab anything that might help him escape from Lua.
“Where do you think you’re going♥”
“Hngh!”
But Sia was pulled back with humiliating ease. Lua had seized his hips and yanked him toward her.
“Ah~ Now I understand why Brother’s hips are spread so wide. They make the perfect handle for me to use. This is your punishment for trying to run away♥”
Squuuueeeelch!
“Nngoooooh?!♡”
Until now, Lua’s cock hadn’t been fully sheathed. This single brutal thrust finally forced the Grand Duke’s entire massive length inside his ass, burying it to the root. Her cock could now feel every inch of Sia’s insides squeezing and massaging it in perfect, satisfying pressure.
“Ah……♥”
“Nngh……♡”
The unbearable mixture of pain and pleasure made Sia’s eyes roll back, exposing the whites. His mouth hung open in a moan, tongue lolling out helplessly.
Plap! Plap! Plap! Plap!
“Ahn♥ Brother! It feels so good! Haan♥ I’m so happy! Aahn♥”
“Hngh?!♡ Nngh?!♡ Haang?!♡”
The lewd sounds of Sia’s asscheeks slapping against Lua’s thighs filled the room. Completely impaled on the Grand Duke’s spear, Sia had been reduced to a powerless doll, helplessly bouncing with every thrust. His twitching fingers and toes, his head shoved into the mattress with hair splayed wildly, even his tongue drooling all over the sheets—Sia, whose mind was already half-gone, could do nothing but twitch and spasm. He offered no resistance at all.
“Ah……! B-Brother……! It’s coming again……!”
“Kgh?!♡ Ghk?!♡”
“Get pregnant……! With my child, the Grand Duke’s heir—get pregnant in your womb, Brother……!”
As the urge to cum overwhelmed her, Lua gripped Sia’s hips and pulled their bodies as tightly together as possible. She thrust her pelvis forward, trying to drive her already-buried cock even deeper. Pouring her load as deep as possible brought the Grand Duke the greatest satisfaction.
The sensation of all his organs being crushed made Sia’s pupils contract.
Spluuuurrrrrt!
“I’m… going… to… knock… you… up……!”
“……Ngh♡”
Sia no longer had the strength to scream. All he could do was twitch feebly. Another thick, cloudy torrent of white gushed into his belly.
Spluuurt! Splurt!
“Hngh……♥”
“……Ngh♡”
The process of filling his insides with his little sister’s love continued for dozens of seconds without pause. Neither of them noticed, but pink heart shapes were flickering in Sia’s golden eyes.
After the long, euphoric ejaculation, the Grand Duke let out a satisfied sigh.
“Huu, huu……♥ After pumping out this much, you’ll definitely get pregnant, right?”
“Haa…… Haa……♡”
If you had actually put it in the right hole, you probably would have.
Too exhausted to speak, Sia could only let out lewd, ragged breaths. Having spent too much stamina, his consciousness began to fade.
“Then shall we go for the next round right away?”
“……?!♡”
Sia’s mind snapped back into focus from pure shock. After unloading such massive loads twice in a row, she still wanted more? As if to mock his disbelief, the Grand Duke’s enormous cock remained rock-hard inside his ass, throbbing with heat and frustration that had yet to be satisfied.
“Lu-Lua, that’s enough now……♡”
“Hnn♥”
Squuuueeeelch!
“Ooh……♡”
Splurt!
“Ugh…… Khh, ugh……♥”
Overcome by an immense wave of exhaustion after her climax, Lua collapsed on top of her sweat-soaked older brother. She had lost count of how many times she had cum—after the sixth load, she had given up counting entirely. The amount of semen her cock produced had decreased compared to the beginning, though it was still far beyond what any normal man could produce.
“Haa…… Haa……♥”
Lua’s body had finally reached its limit. A refreshing emptiness filled her drained balls. Even her monstrous cock finally began to soften and shrink. With clarity returning to her mind, reason flooded back in.
“……What… what the hell have I done……!”
This time, when Lua had lost control, it hadn’t simply been about relieving her lust. She had tried to impregnate her own older brother with her seed. Even if she couldn’t take a husband, how could she have considered filling her own blood relative with child? Why had she tried to do something so insane?
“Brother! Wake up!”
“……♡”
Lua tried to rouse Sia, who lay limp beneath her like a broken doll. He was still reacting faintly, so he didn’t seem to have completely lost consciousness.
“Brother! Brother!”
“……Lua.”
“A-are you o—”
Lua froze the moment she saw her older brother’s face. He wore a blissful, ecstatic smile, looking happier than she had ever seen him. Pink hearts glowed softly in his eyes. He didn’t look like someone who had been tormented all night.
“Brother…… why are your eyes like that……?”
In truth, this wasn’t the first time Lua had seen those eyes. She had simply forgotten because the last time she had been out of her mind.
“Can you… pull out now……?”
“Ah, yes!”
Finally understanding Sia’s request, Lua quickly rose and tried to withdraw her cock. But it was still far too thick and swollen, making the task difficult. Sia’s hole was simply too narrow for something of that size. Thinking only of removing it as fast as possible, Lua accidentally used too much force.
“Haaaaaaaagh?!♡”
“Ah! S-sorry!”
Hearing Sia’s scream, Lua slowly pulled her thick shaft back. Finally, with an obscene pop, the glans slipped free.
“Khh…… Ahk……♥”
“Haan?!♡”
Lua’s cock had grown overly sensitive from repeated orgasms. The stimulation alone was enough to make her cum lightly again.
“Haah…… Haah…… Huh?”
“Ooh♡”
The moment the plug was removed, a flood of semen burst from Sia’s anus. The natural pleasure of expulsion made his body shiver violently as the thick white torrent poured out. At the same time, clear fluid squirted from his front, soaking the bed.
Only then did Lua realize the hole she had been pounding all night was not her brother’s pussy. Thank goodness I didn’t get him pregnant. …No, how could she feel relief after turning a person into a cum dump?
“B-Brother. I made a mistake. I lost control again and—”
“……Hegh♡”
“……Brother?”
Lua knelt beside him, begging for forgiveness, but Sia simply continued to smile with barely any reaction. The pink hearts in his eyes flickered faintly. His ass, still twitching as it spat out cum, jerked sporadically. Looking at the broken-doll state of his older brother, Lua decided she needed to summon the royal physician immediately.
