The Whip, the Carrot, and the Depths of Depravity
In the relationship between the Grand Duke and her brother, the sense of taboo was an absolutely vital element. That special thrill that could only be felt when deliberately trampling on what was considered right and proper. …Sia might feel differently, but that was how Lua saw it.
It was a universal taboo that one should not have sexual relations with family. That was precisely why fucking her older brother like a dog felt so good. Sia still thought of herself as a man. That was why treating her older brother like a bitch in heat was so enjoyable. …The observation that she had long since been completely broken in as a female would be conveniently ignored for now.
“Haa… haa… ♥”
“Nngh… ♡”
Lua had laid Sia down on top of the desk. Her long pink hair spread out like a carpet, covering the entire surface. During sacred work hours, in a space meant solely for official duties, she had turned the work desk into a bed. Every single detail served as a spice that heightened the sense of depravity.
Sia’s wrists were pinned above her head by Lua’s hands, exposing her smooth, pale armpits. Lua loved keeping her immobilized like this. The sight of her helplessly restrained by overwhelming strength difference was unbearably arousing.
She hadn’t removed Sia’s clothes yet. The feeling of violating an unwilling partner added another layer of taboo. Still, continuing with only one hand was inconvenient. Lua released her and began fumbling with her lower garments.
“Haaah… ♥”
Thud.
“Hngh?! ♡”
Lua’s massive cock, lifted along with the hem of the skirt, settled heavily between Sia’s thighs. Its incredible weight made the impact feel more like a slap. Suddenly struck on her clit, Sia twisted and moaned from the burst of pleasure.
“Haa… ♥ Just a moment…”
Lua kept taking deep breaths, trying to calm herself. Having spent the past several days slamming into Mina with full force, she was worried she might lose control of her strength. If she fucked Sia like a beast while this excited, it would be dangerous. Unlike Mina, who could be handled as roughly as one pleased, Sia’s life would actually be at risk.
Sia looked up with sparkling eyes and gave a shy smile.
“You’ll… be gentle with me, right…?”
“…Kh!”
Lua couldn’t tell what Sia’s true intention was in saying that, but if it was meant to calm her down, it was a catastrophic failure. Seeing such an innocent face only made her want to ruin her even more.
“You lewd little slut!”
Riiip!
“Kyaaah!”
Fabric tore apart and scattered through the air like crushed flower petals. Deliberately ripping clothes that could simply be removed was another of Lua’s favorite ways to feed her sense of taboo. Sia’s naked body, a perfect blend of white and pink, filled Lua’s vision and drove her arousal even higher.
“Get that pussy wet already!”
“Eungya?! ♡”
Lua grabbed Sia’s perky breasts roughly, squeezing and kneading them like toys. The act was impossible to distinguish between caress and assault, and Sia’s face genuinely twisted in pain. Yet the way her cunt juices gushed out like a broken dam proved it was clearly effective.
In truth, Sia was already plenty wet, but preparing thoroughly was necessary before inserting something of this impossible size.
“I-I told you to be gentle… ♡”
“Haa… ♥ Shut up. I’m putting it in, so don’t move, alright?”
She had originally planned to engage in more foreplay, but with a pink pussy of heavenly quality right before her eyes, holding back was nearly impossible. Even though Sia wasn’t going anywhere, Lua’s heart grew strangely impatient.
She carefully aligned her glans with Sia’s dripping entrance. The plump, well-trained labia twitched and fluttered as if begging to be fucked.
Squuuuueeeelch!
“Nngoooooh?! ♡”
“Hngh?! ♥”
The overwhelming pleasure spread from the cock that had slid all the way to the root. Her hips twitched, desperate to start pounding immediately, but Lua barely held onto her sanity and looked at Sia. She hadn’t intended to shove it all in at once.
‘Did I… go in too hard?’
Inserting a cock of this monstrous size into Sia’s narrow little cunt required delicate control. She had to spread the pussy almost to the point of tearing and force it inside, but if she used too much strength, Sia’s body might actually break.
“Nnghk, ughk… ♡”
Fortunately, Sia didn’t seem to be injured anywhere. Her pussy was stretched to its absolute limit, and the cervical flesh was bulging outward from the pressure of the cock, but she was simply floating in happiness with hearts in her eyes.
It seemed the brutal expansion Lua had performed last time by wrecking her insides had made insertion easier than expected.
“Uwooooh?! ♡”
Sia came from penetration alone, spraying her juices everywhere. It was only natural. Her long-starved vagina was now packed completely full with no empty space left, and the glans had kissed the lonely entrance of her womb.
Because Sia had thrown her head back in orgasm, Lua couldn’t see her face from this angle—only the smooth white underside of her chin and the bottom of her lolling tongue. Seeing the most beautiful female in her life make such a sloppy expression was strangely satisfying.
But Lua couldn’t simply enjoy it forever.
“F-fuck… ♥”
The mucous membranes felt like they were melting her cock. Even the slightest movement threatened to make her cum instantly. It wasn’t just that insertion had become easier; it felt like Sia’s pussy had been custom-ordered and remodeled into a Grand Duke Cock Perfect Fit, Exclusively Modified Lust Relief Tool ~ Little Sister’s Pussy for Big Brother’s Cock Only ~.
The folds squeezed around her shaft in perfect shape, and the most pleasurable spots wriggled and stimulated her with maddening precision.
“Hah, ngh… ♥”
The feeling of her glans being lovingly licked from every direction made it nearly impossible to hold back even while gritting her teeth. It felt good, of course, but she hated that she was struggling instead of unilaterally ravishing Sia.
“You disgusting perverted bitch…! Can’t you stay still?!”
Slap!
“Eeek?! ♡”
Lua smacked the side of Sia’s breast with her palm. The indescribably sweet sensation that clung to her hand was exquisite. The way the round flesh flattened in a straight line was incredibly obscene. It was satisfying both tactilely and visually, but in the end, it was a mistake on Lua’s part.
When she moved, her own body shook, and Sia thrashed in a mixture of pleasure and pain, clenching hard around her cock.
“Aghk ♥ D-damn it! I told you to stay still… krrgh…! ♥”
Spurtttttttle!
“Nngiiik?! ♡”
In the end, Lua couldn’t hold back and began pumping out thick ropes of cum. Thanks to her tremendous virility, the semen gushed out with enough force to threaten to burst Sia’s womb. The ejaculation that started with heavy spurts didn’t stop even after inflating her uterus to the brim.
“W-what is this?! ♥ U-unniee ♥ S-stop squeezing so hard~ ♥ Aahng?! ♥”
Spurttttle!
“Oohugh?! ♡”
Even in the middle of ejaculation, the inner walls continued to stroke and milk her cock, encouraging more release. Ejaculation was normally impossible to control once it began, but this had gone far beyond that into complete loss of control. Being stimulated nonstop while already cumming felt like her brain was being raped.
“P-please stoppp ♥ Oohugh!? ♥”
Spurrrtle!
“Nngooohk! ♡”
Her mind felt like it was going to break. She even had the illusion that she, the male, had suffered a miserable defeat in this union. Of course, Sia had cum first and was currently experiencing endless orgasms from her womb being battered by semen, so the one who had truly lost was Sia.
Spurt… spurt…
“Krrgh… ♥ Haa… ♥ Haa… ♥”
“Heuugh… ♡”
Finally, the force of her ejaculation began to weaken. Lua panted heavily, waiting for the last remnants in her urethra to finish draining out. Sia looked so blissfully happy that she couldn’t hide her sloppy, drooling smile. She had finally been thoroughly used by the cock she had waited so long for.
“F-fuck… you little… ♥ I-It wasn’t this bad before… ♥ Haa… ♥ Haa… ♥”
Even though she had always considered it the finest onahole, during the few days she had kept her cock out of it, the pussy had somehow become even more vicious. Could this also be the influence of the curse? Lua’s own cock was far larger and more grotesque than a normal male’s, even if its origin was the curse. Sia’s genitals showed no outward abnormalities, but perhaps something inside was different from a normal woman’s as well.
…Whatever. It didn’t matter.
“What are you getting all satisfied about on your own, you bitch?!”
“Hik ♡”
The important thing was that once wasn’t nearly enough for Lua. With her cock still buried inside, she roughly spun Sia’s doll-like body and instantly changed positions. Sia ended up bent over the desk with only her upper body resting on it. Grabbing her soft ass tightly, Lua stood and began swinging her hips in earnest.
Pah!
Pah-pah-pah-pah!
Paaah!
“Aahng?! ♡ Hngh?! ♡ Haang?! ♡”
With every thrust of Lua’s hips, Sia’s body jolted, her firm ass rippling and jiggling. Every time the glans slammed into her cervix, a fresh gush of girl-cum sprayed out and soaked the desk.
“Krrgh ♥ What a pathetic cunt, cumming every time I thrust! How dare you turn me into a premature ejaculator?!”
“Hyaang! ♡ I’m sowwy! ♡ I didn’t mean toooo! ♡”
“You’re still denying it even while squirting like that?! You wanted to get fucked too! Your body can’t live a single day anymore without my cock!”
“Ngh…! ♡ T-that’s not—! ♡”
Even with half her mind gone, Sia stubbornly refused to yield. Because it was supposed to be Lua who needed sexual relief, and she didn’t want their positions reversed. In truth, whether Sia admitted it or not, her lewd female body was already proving it beyond doubt.
Still, Lua wanted to hear a surrender from Sia’s own mouth no matter what. She increased the speed of her hips, pounding so hard that Sia’s ass turned bright red from the impacts.
Thwack!
Thwack! Thwack! Thwack!
Thwack! Thwack!
“Haaang?! ♡ Y-you’re too violent! ♡”
“Ugh ♥ Admit it! Ngh ♥ Admit it right now!”
“Haaang?! ♡ I admit it! ♡ Lua’s cock is the best! ♡ I can’t live anymore without this massive, brutal cock! ♡”
As the giant monster mercilessly hammered her cervix, Sia finally surrendered to her instincts. Lua, intoxicated by the sense of conquest at having thoroughly crushed this female, rode that ecstasy and continued her savage pistoning.
While being thoroughly abused like a broken doll, Sia suddenly made eye contact with someone.
“Ah, t-that, um…!”
“Mi…na… ♡”
It was Mina. Having been ordered to wait, she had eventually stayed and watched the two of them to the very end, unsure what else to do. The sight of such a large woman blushing like a maiden and fidgeting with her fingers was rather adorable.
Sia thought she ought to apologize to her.
“Eungya ♡ Minaaa ♡ I’m sorry for just masturbating in front of you back then… ♡”
“N-no! Brother! I’m the one who should—”
Mina believed that no matter what Sia did to her, she deserved it. Rather, she thought she herself should apologize for doing nothing when Sia had nearly died. But her remorse never reached Sia.
Thwack! Thwack! Thwackthwackthwackthwackthwack!
“You fucking bitch! So you still have the nerve to pay attention to someone else right now?!”
“Aghk?! ♡ N-no ♡ I don’t have any energy left ♡ I completely lost, I swear! ♡ Hyaaaang?! ♡”
With a ferocious expression, Lua mercilessly ravaged Sia’s insides. Under the onslaught that didn’t even allow her to breathe properly, Sia let out screams that sounded like moans.
Lua could not forgive the fact that she had dared to act relaxed while getting fucked by her.
“Shut up! Krrgh ♥ Like the pathetic defeated bitch you are! Hngh ♥ Just quietly take my creampie!”
Spurrrrrrrtle!
“Huaaaaaang?! ♡”
