I'll Call You Big Sister
“I’m going to call you big sister.”
“Puhah♥” “Hueee……♡”
As their lips parted, a long silver strand of saliva stretched between their tongues. Warm breaths rose and mingled in the space between them.
“Haa…… haa……♥”
Lua caught her breath and studied Sia’s face. It was completely melted, as if her brain had been thoroughly broken. Heart shapes floated in her hazy, dreamy eyes.
“Sia, big sister……♥”
“Hueh……?”
“I’m hard.”
Throb.
“Eut?!♡”
Sia looked down at her own lower belly. The cock that had pitched a proud tent under her skirt was stabbing upward as if it meant to pierce straight through the fabric. The intensely stimulating saliva exchange had swollen it to the verge of bursting. As if jealous of the mouth that had enjoyed itself and drooled everywhere, the shaft was now pouring out thick strands of precum, announcing that it too was ready.
They had only touched over clothing, yet Sia’s mind had already dragged her back to the night when that same cock had brutally ravaged her ass. Her underwear was already growing hot and shamefully wet.
“Ah……♡”
“The smell of your pussy is already so thick in the air? You’ll help me, won’t you? Big sister♥”
“B-big sister… if you call me that……”
Sia’s words trailed off. She was grateful that Lua kept calling her “brother,” but she realized she couldn’t keep forcing the issue. After all, she knew there were people like Lina who disliked it.
“If I call you that, then what?”
“……Ah, it’s nothing.”
“Would you prefer I keep calling you brother?”
“Eut……”
“So that’s it, then♥”
“Ha-eut♡?!”
Lua wrapped both arms around Sia and pulled her into a tight embrace. Of course she controlled her strength; if she had truly squeezed with everything she had, Sia’s waist would have snapped in two. Even so, the sudden pressure on her breasts made Sia moan.
“Then act like a man and undo these arms. If you manage it, I’ll call you brother.”
“H-how am I supposed to undo your arms……”
“Just try~”
“Ugh……”
Sia began to squirm inside Lua’s embrace like a newborn kitten wriggling out of its mother’s arms after waking. Her strength was so feeble that Lua couldn’t even tell whether she was exerting herself fully or not.
“Then while you’re doing that~”
Thrust.
“Ha-eut?!♡”
A heavy, thick sensation rose from below, and Sia unconsciously lowered her gaze. All she could see were Lua’s violently large breasts, yet she understood exactly what was happening. The grand duke’s massive cock had lifted Sia’s skirt and forced its way between her thighs. It was pressed against her pussy even through her underwear, lifting her light body slightly off the ground. The monstrous heat radiating from it was enough to set her entire body on fire.
“H-hot……”
“It’s cold here. Doesn’t it feel warmer when we’re pressed together like this?”
“Hauk……♡”
She had to break free from Lua’s arms. Winning by force was impossible anyway, but with that cock pressed against her she couldn’t muster any strength at all. Her lower belly kept throbbing with lewd little pulses♡, and something kept leaking in tiny shameful spurts from below.
Without realizing it, Sia squeezed her thighs together, giving Lua’s massive shaft a delicious, satisfying pressure.
“Now, let’s make a bet. If big sister can escape my embrace, I’ll call you brother. The time limit lasts until this huge thing pulls away from big sister’s first-time virgin pussy. Heut♥”
Gulp!
“Haat!?♡”
Gulp! Gulp! Gulp!
“Haaang?!♡”
Lua began to move her hips. Their thighs slapped together, flesh rippling like waves. The scorching-hot rod kept grinding against Sia’s crotch and pussy. The mixed love juices flowing from both cock and cunt soaked her thighs completely, making any extra lubricant unnecessary.
Slurp! Chup! Scrape!
“Ahut♥ So soft and slippery… kuh, thigh-pussy is the best♥”
“Ha-eut……!♡”
“Big sister, why are you just standing there? Heut♥ If you stay like this, you’ll be my big sister forever, you know?”
Lua watched the melting Sia with an ecstatic, mocking smile. Sia could do nothing but lean her full weight against Lua’s body and desperately try not to collapse. Every time the thick cock scraped her pussy her legs trembled violently, and fresh waves of nectar poured out of her.
“Ah, it’s… coming out… soon… kuheut……♥”
Spurt, spurt, spurt!
“Eut……!♡”
Lua froze her movements, gritting her teeth as she endured the pleasure of ejaculation. If she unconsciously tightened her arms while lost in climax, her precious toy would break. A thin string of drool slipped from between her clenched teeth.
Spurt!
“K-ugh……!”
“Heut……”
All of the semen tangled itself in the hair behind Sia’s legs. The cherry-blossom pink strands were stained a cloudy white, as though snow had fallen upon them. The thick, masculine scent mixed with the fragrance of Sia’s hair and rose into the air. Drunk on that obscene blended aroma, Sia helplessly squirted out her own clear fluids.
“Ahut……! Haat……♡”
“Haa…… haa……♥”
“Hueee……♡”
While Lua was still catching her breath and savoring the lingering afterglow of climax, Sia forcibly suppressed her own desire to melt and threw herself at Lua.
“Hup!”
“Kyahaang?!♥”
Sia’s small mouth closed around Lua’s ear. The soft, wet sensation against her ear was something Lua had never felt before in her life. Her body, still hypersensitive right after orgasm, found the stimulation far too intense. Without thinking, Lua released the arms that had been holding Sia and staggered backward.
Sia, suddenly without support, collapsed onto the floor, but her face was radiant with triumph.
“I-I did it! I won!”
“Eut……!”
“Ah, but your cock was still touching me! S-so the time limit hasn’t run out yet!”
Sia hurriedly added the excuse in case Lua tried to claim the bet was invalid now that she had finished ejaculating. Lua let out a helpless chuckle at the sight of that tiny spark of competitiveness; it was unbearably adorable.
“Brother, do you really hate being called big sister that much?”
“I-it’s not exactly that, but…”
“Don’t worry. I have no intention of letting anyone else call you big sister.”
“Really……?”
Lua nodded with a bright, innocent smile.
Others, huh.
This is my own bitch. I’m the only one allowed to treat her as a female.
Early the next morning, the flying fortress Inarinax rose into the sky. It was to intercept the flying variants among the sub-dragons.
Since Sia was not combat personnel, she was naturally left behind on the ground. He watched the distant Inarinax as it flew away, praying silently that his little sister would return safely.
“Lord Sia. It’s time to return to your quarters.”
“Ah, yes……”
Angelica, the maid standing at Sia’s side, spoke. Dimaria the physician quietly followed behind them as well. She would normally have been required to stay at the grand duke’s side, but the grand duke herself had ordered her to remain with her brother instead.
As he walked behind Angelica, Sia felt a vague discomfort in his chest.
‘Can I really just sit around and rest like this……?’
From ordinary human soldiers to Great Fairies, everyone had marched out risking their lives. Yet even though Sia was a Great Fairy, until Lua returned at night to be comforted, he had nothing to do.
‘At this rate, my only value is……’
Just then, he noticed someone carrying supplies in the distance. At first the armored, large-framed figure looked like a man, but upon closer inspection he realized it was his cousin Mina.
Lua, Lina, Dino, and the other Great Fairies of the Tanalif family had all gone to war, but Mina had chosen to remain behind to protect the base village.
Sia tugged at Angelica’s sleeve and motioned toward Mina.
“Sia, brother?”
“M-Mina. What are you doing? If there’s anything I can help with…”
“……Big sister Lua specifically ordered that brother Sia be allowed to rest.”
“E-even so… I want to be useful in some way……”
Watching Sia fidget and mumble, Mina couldn’t help but smile. As it happened, she had just been thinking how helpful it would be if Sia could assist her.
“Then may I borrow your hands for a while?”
“R-really? What should I do first?”
“Forgive the interruption, but you must not overexert yourself with that body, Lord Sia.”
Dimaria gently rebuked Sia, whose eyes were sparkling with eager anticipation. Angelica nodded in agreement with the physician’s words.
“Please don’t worry. I am fully aware of the situation. We will handle all the heavy labor, so you may simply rest and observe.”
Mina loaded the supplies she carried onto a massive cart. While the other soldiers needed several people to move each load, she handled hers alone with ease.
“These are relief goods for the refugees. I would be grateful if you could accompany me and help with distribution. Even the simple act of brother showing his face will be a tremendous help to the grand duke’s household.”
“Ah, s-so that’s what it was……”
The northwest of the grand duke’s territory was a dangerous region constantly threatened by sub-dragon attacks, yet for that very reason it had become a gathering place for many refugees. Most had lost their homes and fled to escape slave hunters. Since those hunters rarely pursued prey into such a cold and perilous land, the displaced naturally drifted north.
The previous grand duke’s policy had been that only the strong deserved to survive. Refugees were not driven out, but neither were they given aid. Lua, however, believed they were worth showing mercy to and had changed that policy. After all, Dimaria herself had been one of the talented individuals discovered among those very refugees.
“Do you, M-Mina, always carry these yourself like this?”
“Not always. It’s simply that all available hands have been pulled to the barrier at the moment. Shall we go?”
“Mm. ……Whoa!”
“Ah! Brother!”
Fairies possessed far sharper eyesight than humans. Great Fairies even more so. Even from high atop the flying fortress, they could clearly make out the shape of a person slipping on the snowy field below.
A giant wolf easily caught the off-balance baby puppy in its embrace.
Watching the scene, the conversation between the two replayed inside Lua’s mind.
—Brother, are you alright?
—Yeah…… I’m fine. But, Mina…….
—Yes?
—S-seeing you up close like this, you look really c-cool……♡
—Eut…… I can’t hold back anymore……!
—Kyaa♡
“That defenseless bitch is at it again…!”
Of course it was nothing but a ridiculous delusion. There was no chance Sia would try to seduce Mina, nor any chance Mina would fall for it. Lua knew this perfectly well, which was precisely why she had left Mina behind at the base village.
Even so, if Sia kept unconsciously behaving like a female in heat, it was only a matter of time before some other lecherous male tried to claim her. Yet she could hardly bring her onto the battlefield either. She would need to come up with another solution.
“When I return… I’ll have to give her a very thorough education……”
