"Oh my, little brother worked hard again today, didn't he? Big sis is going to praise you a whole bunch!"
"Yay!"
One autumn day, I, the king who had built an unshakable harem kingdom, was renovating this academy, which was to become my eternal paradise. Since I and a handpicked selection of beautiful girls from all over the world would be living a life of non-stop sex, I decided to transform this academy, our home, into something even more magnificent.
From now on, the IS Academy wouldn't be just a school; it would be Arcadia, where my sex slaves would be trained, and where my women and I would live a blissful life of loving sex. To achieve this, in addition to the school facilities, I was using my powers to instantly build new facilities like a resort beach, a leisure pool, an amusement park, a flower garden, and a luxury hotel—all based on requests from the students.
With a strong wish and a wave of my hand, land would rise from the sea, and buildings would assemble on top of it. A construction project like this would normally take years and billions of yen, but with my power, it was over in a matter of seconds. In just a few minutes, all the requested facilities were added to the academy.
The campus had become larger, but since everyone now had a personal IS unit, travel time wouldn't be an issue. Maybe I'll even install warp devices at each facility, like in a video game. I looked down and smirked at the new facilities I had just created, from a bed placed by the window of the top-floor suite, 200 meters above the ground, in a newly constructed luxury hotel. While my secretary, Utsuho, who had helped with the construction, spoiled me, I enjoyed the ultimate view ahead of the other students.
Of course, Utsuho and I were naked in bed, already checking out the suite's amenities. I was being held and pampered in Utsuho's soft, pillowy breasts. To be spoiled to the point of being useless and have sex with a beautiful, big-breasted older stepsister like this was the best life. I buried my face in the valley of her breasts, enjoying her sweet, womanly scent while fondling them. Her beautiful F-cup breasts pressed against my cheeks, changing shape in my hands. Utsuho didn't show the slightest displeasure at me, her naked little brother, acting spoiled in her arms. Instead, she smiled, looking happy to be doted on, and hugged me tighter.
"The facilities you worked so hard to build, little brother, we'll open them up for everyone to use starting tomorrow. I'm sure everyone will be so happy! Ohh! My goodness, you startled me! You can't just bully my nipples all of a sudden."
"I'm sorry! Your breasts felt so good, I couldn't help myself."
"My, oh my, I suppose it can't be helped."
When I pinched her beautiful, cherry-blossom pink nipples with my fingers, Utsuho let out a sweet sigh and shivered. Her voice alone made me incredibly horny. Even when I suddenly went for her nipples, Utsuho scolded me so gently it didn't feel like a scolding at all, and in the end, she'd say, "It can't be helped," and forgive me. She really was the best big sister. It made sense that her true self was so cute and well-behaved. Big sister is the best.
"Utsuho, mmmm."
"Kya! Oh! Hey, now."
And then, I took one of my wonderful big sister's beautiful nipples into my mouth and started sucking on her breast. In contrast to her soft breasts, into which my hands sank completely, her pink nipples were slightly firm and pointed upward. This instinctively made me want to suck them.
"Mmm... Utsuho's breasts... suck..."
"Ooh, nn...!"
I rolled Utsuho's nipple with my tongue and sucked on it with pursed lips. The nipple gradually hardened, and a lewd sigh escaped Utsuho's lips. Her aroused voice made my dick swell and grow hard.
"Ah... ♥ My, oh my, little brother... ♥ You've made your little dick so hard. Big sis will take care of you, okay?"
"Ngh...!"
Noticing my dick had grown, Utsuho's hand reached down. Her slender, beautiful fingers wrapped around my shaft, cupping me in her soft hand.
"Hehe! Grow big! Let's make your little dick feel good, spoiled by big sis's breasts."
"Mmm... Utsuho... suck..."
"Ngh... ♥ There, there... shiko-shiko..."
The hotel, where only we existed, was silent, save for Utsuho's occasional moans as I sucked on her breast. The handjob I was receiving while doting on my big sister's pillowy breasts was the best. My dick, which had been modified to be a monstrous size, quickly arched up and sprang from Utsuho's hand.
"Mmm... ♥ Little brother's little dick is too dangerous... ♥ Any girl would fall for a dick this thick and hard... ♥"
"Aah... it feels so good... a beautiful, gentle, dick-loving, lewd big sister giving me a breast-fed handjob... that's a privilege only I have in the whole world."
"Ngh, yes... ♥ Big sis's breasts are for you only, little brother! Ahh! It's wonderful that you'll use this amazing dick to make so many girls your slaves... it's just wonderful... ♥"
Pre-cum overflowed from the tip of my dick as Utsuho gently stroked me, dripping onto her hand. She didn't show any sign of disgust, just smiled, and continued the handjob with a squishy sound.
"Some cloudy juice is overflowing from the tip of your little dick, you know? Does it feel good, little brother? Do you want to shoot out your cum?"
"Yes... I want to shoot it out on you, Utsuho, and feel good..."
"Alright, where do you want to put it? On my hand like this? Or on my breasts?"
"Your pussy... I want to cum inside you, Utsuho...!"
"Kya!"
My excited, pre-cum-dripping penis was begging me to fuck a woman. I wanted to unleash this beastly desire on my older stepsister, whose face was flushed with arousal from me sucking on her nipple. I wanted to have a cum-in-pussy sex session with her that would make both of us happy, with this perfect view overlooking the entire academy. Acting on instinct, I pushed Utsuho down onto the bed and grabbed her soft thighs, spreading her legs.
"Aah... Utsuho's pussy..."
"Ngh... little brother... don't stare at it so intently..."
"Hooo..."
"Kya!"
I spread the legs of the supine Utsuho and ran my finger along her vulva, which was covered in pubic hair. My finger sank into her plump pussy flesh. When I spread her labia, her beautiful vaginal flesh was revealed. I stared intently at my sister's beautiful, lewd genitals and breathed on them. Utsuho's body shivered violently, and she let out a tearful moan. My excitement grew even more at Utsuho's lewd display, her pussy twitching and her sweet voice moaning. I put my tongue inside Utsuho's pussy.
"Kyaaa! Aah...!"
(A lewd smell...)
As I ran my tongue along her vaginal flesh, Utsuho cried out loudly and arched her back. The female scent emanating from her squirming pussy hole aroused me.
"Mmm... Utsuho's pussy... lick... re-ro..."
"Ah, ah! Your tongue! It's going in... ngh, ahh!"
Chuu, chuku, picha...
My tongue licked her warm folds of flesh. The rough ceiling of her vagina rubbed against my tongue, making Utsuho's body tremble. Warm, viscous nectar dripped from deep inside her vagina, tangling with my tongue. The strong-smelling love juice lubricated Utsuho's genitals. I felt a dizzying, rich female scent, and I caressed Utsuho's thighs.
"Mmm, mmm, chu."
"Ah, no, kyaa! Little brother's tongue, ngh, rubbing my pussy, I'm going crazy...!"
With my face trapped between her thighs, I used my tongue to loosen my sister's genitals. Every time Utsuho moaned, my dick pulsed, begging me to offer it to the female in front of me. Just as Utsuho's vagina would gently envelop my huge dick, I carefully ran my tongue along the ceiling of her vagina, collecting and swallowing her love juice. The hot, thick nectar passed from my tongue to my nose, arousing me.
"Mmm... haa...!"
"Ah, it's coming out... nooo..."
When I pulled my tongue out after the nectar overflowed from deep inside and I could no longer scoop it up, Utsuho, who was about to climax, cried out in sadness. The eyes behind her glasses were watery, her expression was melted, her nipples were hard and pointed upward, and she was glistening with sweat. Love juice dripped from her vagina, and she was panting and writhing. The sight of my older sister in this disheveled state filled my mind with lust.
I sat up and pointed my erect dick at Utsuho. The veiny dick stretched from my crotch to Utsuho's navel, showing her what would happen if I inserted it.
"Ah... ♥"
Utsuho saw my thing pointed at her and let out a dreamy sigh. The cute sister, whose eyes were full of expectation as she stared at my cock, made me want to have sex with her even more.
"Utsuho... I want to have sex..."
"...Yes... put your hard, hard little dick inside big sis's pussy and feel good... ♥"
Utsuho smiled gently, and with her fingers, she spread her pussy herself, inviting me in. The saying goes, "Don't refuse a prepared meal." When a beautiful older sister like this asks, I'll naturally enjoy her deliciousness. I pressed my penis against Utsuho's crotch and inserted it.
"Ahn... little brother's is... so big... ♥"
My dick pushed open Utsuho's wet vaginal hole and went inside. The thick cock rubbed strongly against her folds of flesh, stimulating her erogenous zones. Utsuho's vaginal muscles also intertwined with my cock, squeezing it tightly. Wrapped in her warm flesh, it felt good just to be inserted.
"Mmm... Ahn... ♥ Little brother's is coming inside... ♥ Aaaahn..."
"Aah... the look on your face, Utsuho, when you feel it, is so lewd... It's already this thick and hot just from the insertion..."
"Ah! It's here, mmm...! It's going to reach the back...!"
"Kuh, uaaaaah!"
"Nnnn!"
Utsuho's arms clung to me as if in resistance. I thrust my hips forward, burying my dick deep inside her. Utsuho's vagina swallowed my whole thing, and she lightly climaxed from just the insertion. Her slippery flesh tightened all the way inside, trying to squeeze out my sperm.
"Uaaah... it's in!"
"Ah, aaah! Mmm, a big one has reached the back...! Mmm!"
Utsuho wrapped her arms and legs around me, hugging me tightly. I enjoyed her soft, sweaty body pressed against mine while letting Utsuho's pussy get used to my dick. The pussy, which had been filled all the way, writhed and the folds of flesh remembered the shape of my shaft, sticking close to it.
"Haa, haa..."
"Haa, haa... mmm... ♥ It's in... little brother... umm ♥"
"Uah, Utsuho's pussy, it's swallowing my whole dick..."
"Yes! ♥ Little brother... move...? Make your little dick feel good in big sis's wet, lewd pussy, ahh ♥"
Enduring the pleasure of being fully penetrated, Utsuho smiled to reassure me and asked for more. Touched by my big sister's kindness, I slowly moved my hips, rubbing my dick against her vaginal flesh. The wet, narrow pussy rubbed against my penis, creating pleasure.
"Kuh, Utsuho...!"
"Mmm! Ah, ahn! ♥ Little brother's... mmm, thick one is moving...!"
My dick was being handled in a way that was different from how my sister's true self would do it, and the erogenous zones were rubbing against each other. As I pumped my hips in and out, Utsuho's voice became sweeter and sweeter. Utsuho's pussy gently enveloped and tightened around my thing. The rubbing of our genitals created a climbing pleasure, and I felt a sense of unity.
"Uk, mmm...!"
"Ah! Ahn! ♥ Does it feel good? Ahn, little brother...? Mmm... Ahn! ♥"
"Aah, it feels so good... Your pussy is the best, Utsuho."
Squish!
"Ahn! ♥ Really? Mmm, big sis is so happy to be able to please you, yaah! ♥"
I was also happy to see Utsuho so pleased to accept my dick. Nupu nupu, we slowly thrust our hips in our hotel, devouring each other's pleasure.
"Utsuho... I'm about to..."
"Ah-hee, ahn... ♥ It's okay... ahn... come... inside big sis's pussy... ahh ♥"
"Uah... kuh..."
"Ah... ♥ Ahn... big... nnnn...!"
"Uuu..."
...Biyuru! ...
"Ah, ahn...! Nnnn... it's hot...! Nnn...!"
"U, aaaaah!"
In a slow-sex session that we built up carefully, I came deep inside her. Utsuho shivered, taking my semen raw.
"Ah... ♥ Nnn... it's amazing... little brother's sperm... it feels so good... ♥"
"Kuh... for such a gentle big sister to let me do it raw... it's too good...!"
"Mmm... ♥ My, little brother...? You can do whatever you want with any girl in this world, you know? Big sis will also have sex with you anytime you ask."
"Utsuho... mmm..."
Utsuho, who had just climaxed from having semen directly ejaculated into her uterus, had a sweaty, flushed, and lewd face. In the languid exhaustion after ejaculation, Utsuho hugged me and stroked my head. This sweet big sister is the best. As we hugged each other with our sweaty bodies, we once again looked at the magnificent view outside the window.
"But the sky and the sea are really beautiful, aren't they, little brother?"
"Yeah. I wonder if the night view will be pretty, too?"
"Oh, that's a good idea! For the pre-opening celebration, why don't we invite Honne, Tatenashi, and everyone else for a party?"
"A party... if it's a party, it'd be nice to have an orgy with my favorite girls lined up on this top floor."
"Hehe! ♥ After you came so much inside big sis, are you already talking about sex? Big sis might get angry, you know?"
Sweet Utsuho wasn't scary at all when she was angry; she was just cute. Unable to hold back, I pushed Utsuho down and entered the second round.
