The Bathroom of a Collapsing Relationship
The bathroom door in their collapsing relationship was made of translucent glass. Had anyone been standing outside, they would have witnessed the obscene sight of Sia’s cheek and breasts plastered flush against it, lewdly crushed and deformed by the pressure.
With Sia’s beautiful legs spread straight apart, Lua drove her monstrous cock between them. She moved with the careful precision of a mind gone mad, determined not to slip and enter the wrong hole like last time.
“Uwoh… ohk…♡”
Sia’s labia writhed wetly as they swallowed the tip of Lua’s glans. The ridge had not even entered yet, but Sia was already shuddering from an electric jolt racing up her spine. Her expression began to melt into a sloppy, pleasure-drunk mess. In contrast, Lua frowned in clear dissatisfaction. Despite how soaked they both were, proper penetration still refused to happen. Yet she could not simply force it; if she did, Sia’s womb would be crushed beyond repair, leaving her unable to bear children.
“Relax your body, sister.”
“Aahng…♡”
Sia’s strength was no more than that of a frail human; it posed no obstacle to a Grand Elf like Lua. The only problem was the sheer, impossible size of Lua’s cock. Sia’s pussy was tight, but for her build it was within normal range. Lua’s monstrous organ, however, had long since transcended any ordinary standard.
“No helping it, then. This might hurt a little—”
Thrust!
“Ughk…?!♡”
“Khh…♥ Bear with it for me, will you?”
Lua carefully flexed her hips and began pushing the massive shaft inside. The ridge of her glans finally breached the entrance. Sia went rigid from the shock, as though a stake had been hammered into her core. The Grand Duke’s enormous member pried open the narrow passage and inched forward with brutal persistence. Every scrape against her inner walls sent Sia trembling with a sexual sensation so foreign it felt almost terrifying.
“L-Lua… take it out… take it out… I’m turning weird… ohhk…♡”
“Stay still, damn it…♥ Just stay still!”
There was another reason Lua had to move so slowly. Her cock, starved for four full days, felt ready to explode at the slightest provocation. Yet Sia’s depraved little cunt felt far better than anything she had imagined.
‘What the fuck is this…♥ Th-this is a real pussy…♥’
The size difference created crushing pressure around Lua’s shaft. Of course, Sia’s pathetic cunt was nowhere near strong enough to resist her steel-hard cock. The inner folds scraped and clung greedily with every inch, as though the lewd hole itself were trying to guide the invading member deeper. The vanguard already buried inside was drowning in pleasure so intense it threatened to melt.
“Khh… I said relax… haa…♥”
“Oh, goooh…♡”
Having held back for so long, Lua had wanted to savor every moment before she came. At this rate, she feared she would finish before even getting fully inside. Was a woman’s pussy truly supposed to feel this good? It shouldn’t be. Normal intercourse could never produce pleasure this overwhelming. The only explanation that came to mind was the curse.
Lua’s cock was an aberration that defied comparison with any other male, as its ridiculous shape made obvious. And though Sia’s cunt appeared ordinary from the outside, it was clearly far more pathetic, vulgar, and shamelessly lewd than any normal female’s.
“God… damn…♥”
“P-please… take it out… nngh…♡”
Sia’s face had frozen into a foolish expression that was neither smile nor tears. Lua’s temper finally snapped. She had always believed herself completely in control, yet this pathetic older sister seemed to be pushing her to the brink.
“You filthy fucking slut!”
Grind!
“Ah, ack…?!♡”
Giving up all restraint, Lua slammed her entire length into the deepest part of Sia in one brutal thrust. In that instant, Sia felt something she had never wanted yet also never wanted to lose vanish forever. The devastating realization sent tears rolling down her cheeks. A mixture of blood and slick juices leaked out along Lua’s massive cock. The pain—or perhaps the twisted joy—of losing her virginity made Sia’s slender toes curl tightly.
“It h-hurts… hngh…♡”
“Khhhuu—♥”
While Sia moaned in distress, Lua was savoring the sensation of most of her cock being devoured by that tight heat. The inside of the pussy wrapped around her meat rod like a custom-fitted sleeve. Still, it was not enough.
“Haa… haa…♥ Sister, can you feel it? My fat meat club is already pressing right against the entrance to your baby room.”
“Nngh…”
“But… it’s still not all the way in, you know?”
“…What?”
“Here we go♥”
Thrust!
Lua snapped her hips forward, forcing even the root inside. The brutally expanded channel gave way as the cock crushed all the way up to Sia’s womb. The bulge in Sia’s lower belly was clearly visible from the outside. Her eyes rolled back, tongue lolling out with a broken moan.
“—Ka, haak…!♡”
The womb that had been crying out in needy little sounds, begging to fulfill its purpose as a female, was now being directly hammered. The resulting storm of pleasure slammed into Sia’s brain, nearly shattering her consciousness. Squirting obscenely, she climaxed violently right on the edge of passing out.
“Oohk♡ Ohhhoohk♡”
“Cumming all by yourself? I’m only just getting started♥”
Slap!
“Ohhgooook?!♡”
Slap! Slap! Slap!
“Ah! Fuck! This feels so fucking good!”
Lua began swinging her hips, pounding in earnest. The wet skin of the two women slapped together obscenely, rippling like waves. Sia’s rolled-back eyes returned to focus as her fading consciousness was dragged back by force. Her lower belly kept bulging outward with every thrust. Each impact against her womb sent heavy, seismic waves of pleasure echoing through her body.
Lua had little experience wielding her cock and therefore possessed no refined technique. Yet the sheer overwhelming size and power alone drove Sia to the absolute limit.
Slap! Slap! Slap!
“Haa♥ Haa♥ Genuine incestuous climax mating with my beloved sister Sia♥ This is so fucking incredible♥”
“Nghok♡ D-don’t… call me sister… ohhk♡”
Lua’s eyes curved with wicked amusement as she drank in the sight of Sia’s obscene body. No matter how many times she looked, it was beautiful—but the way Sia was forced to stand on one leg with her thighs spread straight apart was unbearably arousing.
“Trying to play the older sibling with a body this lewd was doomed from the start!”
“Nooo♡!”
The mixture of their juices and blood kept flowing out, coating Sia’s smooth thighs and Lua’s rigid cock. Combined with their sweat and the humid air of the bathroom, the filthy scent of sex soon saturated the entire space.
“Haa… haa…!♥”
Slap! Slap! Slap! Slap!
“Ahk!♡ Nghh!♡ Hoook!♡”
The urge to cum surged through the cock that had been joyfully pumping out slick. Lua hesitated. She wanted to cum. She didn’t want to cum. It would feel amazing right now, but holding back just a little longer would feel even better. Enduring for the sake of a superior future was a Grand Duke’s virtue. Yet Lua no longer had any restraint left to give.
Slap! Slap! Slap!
“Sister… sister…! I’m… I’m about to cum…!♥”
“Hngh?!♡ W-what? No! You can’t cum inside!”
Sia thrashed desperately, trying to pull the cock out. It was not too late. Taking her virginity and drowning her in pain was something she could endure alone. No matter how the cursed family trash was treated, it would not cause any real problem. But being creampied was an absolute catastrophe that could not be allowed to happen. If Sia were to become pregnant, it would leave an indelible stain on Grand Duke Lua Tanalif.
Yet Sia’s pathetic resistance only fueled Lua’s savagery.
“You fucking bitch! Ngh♥ You perverted masochistic cunt bitch! Shaking this lewd body at me so openly, begging to be filled with my cum! Telling me not to cum inside is completely unfair!”
“Haaang♡ Don’t…! Haang♡”
Grabbing Sia’s long hair like reins, Lua yanked her head back and slammed into her at full speed for one final sprint toward climax. Beyond the foggy glass, the artistic sight of those soft breasts being violently crushed would have been completely visible.
Slap-slap-slap-slap-slap-slap!
“I will definitely impregnate you! I will absolutely impregnate you! I will impregnate you no matter what!”
“Nooo…! Haaang♡ Don’t get me pregnant♡ I don’t want a baby…! Haang♡”
“It’s coming… thick and hot…! Irresponsible incestuous mating, creampie, I’m cumming…! U-uuooohhh?!♥”
Spurrrrrt!
“Haaaugh?!♡”
The Grand Duke’s massive cock began pumping out thick, white, sticky, scalding fluid in heavy bursts. The pleasure radiating from her cock was so overwhelming that the rest of her body felt numb. Wearing a stupid, pleasure-drunk expression, Lua buried her glans as deep as it would go and held it there, waiting for the ejaculation to finish.
“Oh… ohhk… k-khh…♥”
Spurt, spurt!
“Ahh… kahk…!♡”
Head thrown back, tongue hanging out, Sia kept spilling moans and drool. The endless torrent of thick semen hammered her cervix without mercy. Each impact forced another squirting climax from her, psh-psh, until her mind began to fracture. The constant pressure made it hard to breathe. Her breasts squashed against the glass door spread out like dough.
“Haa… haa…!♥ C-crazy…♥ This is wrong… the cum… won’t stop… ohhhoohhk?!♥”
Spurt!
“Ahk?!♡”
The ejaculation refused to end. The absurd volume of semen made Sia’s lower belly feel heavier and heavier as it swelled. Gush… gush…!
“Khhhuuk…♥”
“P-please… stop… I’m going to lose my mind… nghh…!♡”
Four days’ worth of pent-up semen was not only enormous in quantity but so thick it even carried a yellowish tint. Both of them had to fight with everything they had just to endure the suffocating pleasure. A normal person’s orgasm did not last for whole minutes. Even a brief climax could bring supreme ecstasy. Yet this marathon of pleasure was being inflicted without pause on Lua’s hypersensitive cock and Sia’s equally sensitive womb.
“Aah…♡”
In the end, unable to withstand the overwhelming, superior ejaculation, Sia let out one last short sigh and fainted.
A faint pink glow began to shimmer across her lower belly, now swollen tight with cum.
