The Grand Duke's Endless Torrent
Sia let out a sweet, trembling moan. “Ahhht♥ Haang♥!” “Haaah… haaah…♡”
Lua’s hip strength was anything but ordinary, befitting a Grand Elf. Sia’s ass had already been reduced to a complete mess just from the constant impacts against the Grand Duke’s lower body. On top of that, it had taken several blows from the Grand Duke’s palm, leaving it swollen in a truly obscene, lewd shape.
“Uht… haaht…♡”
Sia, breathing in those coquettish gasps, couldn’t even keep her eyes properly open. Her pink hair was a disaster, soaked and dripping with sweat. A cock so enormous it felt like it was crushing all her internal organs was stirring violently inside her; physically, she had reached her limit.
Thwack thwack thwack thwack!Thwack thwack thwack thwack thwack thwack!
“Haa… haaaa…! It’s… it’s coming out now♥!”
As the moment of climax drew near, Lua began slamming her hips even faster than before.
“Nnghoooook♡! W-wait, just a—!”
Sia had no confidence she could stay sane if she was made to cum in a state this hypersensitive. She tried to dissuade Lua with slurred, leaking words, but of course none of it reached the Grand Duke’s ears. The rope binding Sia’s wrists had turned them an angry red from all her desperate struggling.
“Kgh, I’m… gonna cum…!”
“Ah, aahng♡ No, don’t—!”
Lua gripped Sia’s pelvis—perfectly sized for her hands—and drove her cock as deep as it would go. It was already buried to the absolute limit, yet she pressed down on her brother’s ass and forced it even deeper.
“Oohuuk♥?!”
Spurrrrrt!
“Hauk♡?!”
The Grand Duke’s monstrous member began spewing thick, viscous white fluid. The sensation was like having molten lava poured into her; Sia instinctively tried to pull away from Lua.
Squeeze!
“Kyaaak?!”
Lua unconsciously grabbed a fistful of Sia’s hair and yanked. She had felt the cock slip slightly out of that tight anus.
Glurk… glurk…
“Khuuu…♥ To think I’d fill my irresponsible big brother’s insides like this…♥ Not a single drop left behind…♥”
“Auk… heut…♡”
Lua’s body tensed with the unrelenting force of her orgasm. As a result, Sia was pulled backward by the hand in her hair, her fragile, flower-stem-like body arching dangerously.
“Just… a little more… I’ll give you a bit more… ohhuuk♥?!”
Spurrrrk!
“Haung♡?!”
The hot river flowing through her belly finally broke off after one last short, powerful spurt.
“Haa… haa…♥”
“Heuk…♡ Haht…♡”
Glurk… glurk…
Lua’s face was drenched in pleasure and ecstasy. She panted hot breaths, savoring the afterglow. She relaxed her body and enjoyed the sensation of the last remnants in her urethra trickling into Sia’s depths. Between her loosening fingers, Sia’s hair slipped free.
Once the pulling force vanished, Sia’s head flopped forward and slammed into the bed. Simply enduring Lua’s violent torrent had completely drained what little stamina Sia possessed.
“Haaah… haaah…♡”
Sia’s eyes had gone completely unfocused, heart shapes floating in her pupils. With her tongue lolling messily across the bedsheets, she panted like a heat-exhausted beast.
The Grand Duke looked down at her brother’s ruined state with a sly, wicked glint in her eyes.
“Big brother…♥ Be honest. You liked it too, didn’t you? The way your ass keeps twitching and clenching♥ like that.”
“…Uht.”
Sia wanted to deny it, but she had no strength left to speak. Her pelvis shivered with aftershocks and her ass trembled, but that was simply because her body had gone limp. It wasn’t because she felt any satisfaction from the powerful male seed that had been pumped into her belly, even if it had been poured into her rear. Absolutely not.
“By the way, big brother.”
At the sound of her name, Sia rolled her eyes to look at Lua. Beyond her own pitifully twitching female ass, she saw Lua’s icy expression and felt a jolt of unease.
“Uht…?”
“What are you doing… resting like it’s all over?”
Thrust!
“Huuuuhk♡?!”
The heart pattern in those golden eyes trembled precariously. Lua had begun moving her hips again.
Splat! Splat! Splat! Splat!
“Aaaang!♥”
Spurrrrrt! Spurt! Spurrrrk!
“Haaauuung?!♡”
And so it continued—two loads, three, four, and on and on. No matter how many times she came, Lua’s erection refused to subside. The Grand Duke’s build was only about average for a woman. No one could fathom where all that overflowing semen was coming from.
Sia, whose stamina had long since hit rock bottom, was half-conscious. She felt nothing but pleasure and pain, simply shaking like a doll.
“Ah… ugh…?”
It was only when the movements she had been dimly aware of finally stopped that Sia’s foggy consciousness resurfaced. The semen that had completely filled her belly was now gurgling out of her anus, sliding down her smooth thighs.
Thinking the pleasure-filled hell had finally ended, Sia cautiously tried to lift herself up.
Thrust!
“Haaang?!♡”
“Did you think it was over?♥”
“A-ahhh…”
Sia sent a trembling, disbelieving gaze toward her own rear. She could feel the still rock-hard massive cock throbbing inside her, plugging her passage completely.
“Haa…♥ That expression the moment hope turns to despair…♥ It’s just too adorable…♥”
The Grand Duke gazed at her sister’s face, flushed with rapture, and gently stroked her brother’s quivering ass with loving hands. Then she brought her lips close to his ear.
“Big brother… you really have to follow me, don’t you?”
“Ugh…?”
“To the Northwest Barrier, I mean.”
“Ugh…”
It was little more than the babbling of an infant, but Lua understood it as affirmation.
“At the Northwest Barrier, I’ll be fighting every single day. You might not know this, big brother, but battle excites the body. In that heated state, I might become even more intense than I am right now.”
“Haaau…?”
Even at this level her body was already falling apart—yet she was saying it could get even rougher? If that were true—
“Th-that means… you’ll need me… even more…”
“…Pardon?”
“You want me to… just leave my little sister… suffering every single night…?”
Sia still remembered the day Lua had first taken her. The sight of her little sister walking alone down an empty corridor, struggling with every step. She had never imagined that the Grand Duke—whom she had believed to be stronger than anyone—could ever look so burdened.
No matter how pathetic a brother he was, he could not simply watch his little sister fight alone.
“…Ha.”
Lua let out a scornful laugh.
“Right now, a weak, pathetic brother like you dares to worry about me—the Grand Duke?”
Slap!
“Ahk♡?!”
Once again, Lua’s palm struck Sia’s utterly ruined ass.
“You insolent bitch…!”
“I-I don’t want thaaat♡!”
Crushing her brother’s pure determination to protect his sister, Lua began stirring Sia’s insides once more.
“…Uht.”
When Sia opened her eyes again, she was lying naked on the bed.
“…Ah.”
Her throat felt like it was cracking apart with pain. She was severely dehydrated after pouring out sweat, tears, saliva, and pussy juices without restraint.
Sia tried to sit up in search of water, but there wasn’t a single ounce of strength left in her body. She was trembling, trying desperately to move, when—
“Big brother…”
“Hiiik!”
Lua wrapped her arms around Sia from behind. Hadn’t they already gone at it for nearly half a day? Was it still not over? Overwhelmed by the Grand Duke’s absurdly inexhaustible stamina, Sia’s repeatedly ravaged ass shivered with fear.
But even after a long while, the massive cock did not thrust into her hole again.
“…Because of me… mmm…”
“…Phew.”
Thankfully, it seemed Lua was talking in her sleep. Letting out a sigh of relief, Sia tried once more to get up, but she couldn’t possibly move Lua’s arm with her own power.
She didn’t want to wake her little sister, who had barely slept and would soon have to prepare for deployment. With no other choice, Sia grabbed Lua’s arm and shook it.
“Um… Lua…”
“…Mmm, big brother?”
“S-sorry for waking you. My… my throat is so dry…”
“…Ah. Water… I’ll get it for you, so stay right there.”
“Ah, no, I can get it myself…”
Lua rose first. A moment later, the sound of water pouring into a glass could be heard. Sia tried to sit up somehow, but her body gave out and she collapsed again.
“Big brother? Are you alright?”
When she looked up, Lua was already standing there holding the glass.
“I-I guess I’m a little tired. I’m… so weak…”
“…It’s not that you’re weak, big brother. The problem is that I’m too strong.”
“Huh?”
“…Hehe. Just stay still for a moment.”
“Hweh?!”
The scenery around her spun wildly in a disorienting blur. When she came to her senses, Lua was sitting on the bed, cradling Sia in her arms. It was the exact posture a woman might use to hold a baby.
“Now, open your mouth just a little.”
“Hweh…?”
Lua brought the glass to Sia’s lips and tilted it. Cool water flowed in slowly. Gulp. Gulp. The sound of swallowing echoed from her small throat. The cold temperature seemed to clear her head.
“Hehe. You’re too cute.”
“Uuu…”
Lua smiled with a faint blush. Sia’s face burned bright red with embarrassment. She wanted to protest being treated like a baby, but if she did, the water would spill, so she endured it.
“Good job~”
“Uuu…”
The scenery spun again. At some point, Sia found herself lying in bed with the blanket pulled over her. Lua had gotten off the bed to put the glass down.
“L-Lua…”
“Yes?”
“You… you’ll take me with you… right…?”
“…Alright. You win.”
After setting the glass on the table, Lua returned to the bed and kissed Sia’s forehead. Then she slipped her hand under the blanket and gently stroked his soft lower belly.
Just being aware of the semen filling him made Sia’s entire body feel hypersensitive.
“Instead, you’ll really need to steel yourself for tonight, okay?♥”
“Hweh♡”
