Yami and Momo
"Haaah...aaah...no, pull it out! Get off me! Haaaah~ ❤" a pretty, golden-haired girl moans while lying on a bed in the nurse's room.
"Yami-chaaaaan~ ❤ You're so lovely, and you feel so good! I'm going to cum inside you soon!" the obese middle-aged man on top of her roars.
*PLAP PLAP PLAP PLAP* Greedily his cock plunges inside Yami's cute little vagina, while he's in a pronebone position. Her toes curl in pleasure as she keeps getting pounded over and over, and a deep blush is on her face as she feels his sweaty body rub against hers. Why? She hates this pervert! Why...can't she resist him? Again and again he jumped her. She used to fight him off, but her far more perverted alter ego, Darkness, made her give in once. And like a wild beast, he greedily devoured her body. Years and years of pent-up lust were unleashed upon her small features, and she came again and again under the body of the old fatso as he slammed his dick inside her. And now she's hopelessly addicted to his middle-aged cock.
Her petite self gets dominated completely by his blubbery body, and his pleasure-filled groans sound in tandem with her little shrieks. "Aaaah...aaah...feels good...❤" she pants.
"Yami-chan...Yami-chan...I'm cumming! Have my babies! Get pregnant from the man you say you hate so much! Muhyoooo!" he yells, followed by him bucking his hips against her stronger than ever, and causing her to have an orgasm herself while he fills her pussy with his seed. Yami puts her head against a pillow and muffled moans can be heard. Her whole body shivers in pleasure.
"I love you~ ❤" she whispers softly, but loud enough that he can hear. A passionate kiss is his response.
And while those two go at it, another person is moaning softly. She has been peeping at them around the corner. And seeing them go at it, made her unable to control herself. She has her hands in her panties and her heart-shaped tail in her mouth. Yes, it's Momo. The 14-year old short-haired pink-haired princess of Deviluke, little sister to Lala. And a young girl who is pretty much perpetually horny.
Time and time again she tried to seduce Rito Yuuki - both to participate in her 'harem plan' to unite all girls and make him King of the Universe, and to just indulge in her lust. But he always, always, always refused. Waffling back and forth, taking three steps back from every step he did take forward. It was incredibly frustrating. And now that his sister Mikan's gone missing, he's lost any and all interest in her. Understandable to some degree...but even her patience has its limits. It was time to admit she was wrong. A guy like him...could never become King of the Universe. To do so, you needed to be driven, undaunted and have the ability to dominate people. You know, like the man who kept trying to molest the cute golden-haired assassin. Time and time again he got beaten up, to the point of getting nearly killed. And yet he kept going and wormed his way into her heart. That girl is now moaning in pleasure underneath his big, fat body. The Principal...Momo initially wrote him off as just a perverted, fat, middle-aged man, but she had to respect his strength. And with that respect, came an attraction. Sweaty, obese and middle-aged...getting dominated by that man might be utterly different than anything she would experience with Rito, but her young pussy gets wet at the thought of it. It was so wrong, so naughty...and yet it felt so right. Hearts were in her eyes as she suckles on her sensitive tail again. Maybe...she should seduce him instead?
And so, she sneaks out. Only to return the next day, going to his office alone. Dusk is falling, and he is surprised to see her.
"Muhyoo! Momo-chan! What can I do for you!" he says excitedly.
"Mr Principal, I wish to discuss a proposition with you," she says nervously, as she positions herself next to his chair. Her nervous heart is beating fast - is she really going to do this?
"Of course! Anything for a cute girl like you!"
Momo swallows. Lustful as she might be, she wás still a virgin. "Here goes..." she thinks.
"Have you ever heard of the Harem plan?" she asks. His eyes glint. "...my sister, Lala, is the crown princess, and whoever marries her ends up as the King of the Universe. A role that takes strength. Both in terms of fearlessness...and avoiding conflicts among the harems they create. My father's an exception in that he was truthful to only one woman, but most others...
Momo balls her fist and puts it to his chest. "Lala is, or was, in love with Rito Yuuki, so I tried to guide him into it. But he's not up to the task. But you, sir? The one who tamed the feared Golden Darkness? Y-you...might serve as that person. A-and I can help you with that."
A grin appears on the Principal's face. "My, what an interesting proposition. I've been keeping an eye on all of you, you know. I've been wondering where that development was going. Nowhere with Rito, it seems. But you realize what that means, right, Momo?" The principal grabs her arms, slams her down on the desk and stands lurched over her. "To start with this 'harem plan', I need you to show me your resolve as well."
The teenage girl is now lying in front of him. Her skirt has been pulled up a bit, exposing her white panties. Her legs are wiggling back and forth. She's panting and blushing, and her heart is beating in her throat. But Momo...Momo's resolve is firm. "Mr Principal...make love to me..."
The moment he hears those words, he pounces on her. He holds her arms down and kisses her full on the lips. His middle-aged tongue violates her pretty little mouth. When he finally removes himself, Momo is lying there with a dreamy look on her face. She hears the sound of his pants dropping and other clothes falling off and looks up.
A big, stiff, middle-aged cock is standing at full mast, alongside the rest of his naked, fat body. Momo, in a haze, takes her shirt off as well, exposing her perky young breasts. She keeps on the skirt, but her panties do hang loosely around her legs. And with his big, strong, adult arms, the Principal lifts her up from the desk, sits down in his chair and lowers her down. Her small body is like a plaything in his arms. She feels the cock poking her teenage slit, until, finally, he enters. Smoothly the large adult cock slides inside, going balls deep inside her. Momo is a virgin no more.
And as he begins pumping inside her, she finally, finally, finally gets what she has wanted all this time. The perpetually horny Momo finally has sex. Not with some clumsy teenage boy, as she expected, but an obese middle-aged perverted fatso. And given how utterly wet her pussy is, she thoroughly enjoys this experience. She moans erotically as the big middle-aged cock pounds her, and his balls slap against her ass. The Principal holds her tightly in an embrace against his fat body, licking the sweat off her neck and rolling his tongue over her upper body. She is completely at his mercy and gets fully dominated, and hearts are in her eyes. And she starts squirming in pleasure even more when he starts suckling her delicious breasts, while sinking his fingers deep inside her tight little ass.
"Mr Principal...Mr Principal...I...aaah...i-it feels so...aah...so goood..." she pants, sounding far more like the little girl she is than the seductress she always attempts to be.
"Muhyooo! Momo! Your pussy, it feels amazing! I'll conquer you! I'll conquer all of you! Mark my words! And all of you, all of your little friends...will get pregnant with my babies!" he roars, emphasizing every single one of his words with a hefty pound in her pussy.
"Yesss...yessss....conquer ussss...teach us all our place..." she gasps, louder and louder, until she orgasms. Her nails sink into his blubbery body, she feels light-headed and she shivers over her entire body. It's the best orgasm she's ever had. And while she's still in that state, she hears a large groan and feels a warm feeling filling up her belly. His seed is inside her now. Maybe she'll get pregnant from this first shot already...
Of course, their lust isn't satisfied yet. So he also fucks the shit out of her on his desk, pounding his student, a cute schoolgirl, right on top of all his business papers. Truly setting an excellent example for a school principal. He has her tail in his mouth and suckles on it, which turns her brain even more into mush. After another orgasm, she gets pounded pronebone style as well. His heavy body is on top of her, pounding his big cock inside her pussy, while she can't even move. And she loves it.
And finally, after a long love-making session, she is sitting in front of his chair again, sucking his cock. Cum is still dripping out of her pussy. And she looks natural doing so - Momo is meant for the cocks of oji-sans, she realizes that now.
"That was amazing, my dear," the principal says while stroking her head.
"Thanks, master," Momo happily smiles.
"Well then. We have quite the task ahead of us. Let's start this...'Harem plan' tomorrow," the principal grins. Momo follows him back home, where she falls asleep in his fat arms, more content than ever. Dreaming of all the fun times to come.
*The next day*
Nana, Lala and Momo
"Aah, aah, aah!" *PLAP PLAP PLAP!*
The moans are coming from Rito's house, where Nana, Momo's petite, flat-chested tsundere sister, has a big middle-aged cock inside of her now. She's lying on her back, while Momo is holding her arms down. Her small body forms quite a contrast with that of the obese man bucking his hips against her.
"Muhyooo! This loli pussy is nice and tight!" the Principal excitedly exclaims.
"Please...noo...aaah...not...this...ugly bastard..." Nana screams, but her pathetic resistance and the way she's squirming isn't very convincing.
"Oh, Nana. We're twins, I know what you really feel. The pleasure...it's amazing, isn't it?" She lovingly strokes her hair while she says it. Was about high time her uptight sister learned to experience the adult world, she thinks.
"It..it...doesn't....feeel....aaaah~" Nana's tongue is hanging out of her mouth as her body accepts getting bred by the fat middle-aged man. She can't ignore her natural instincts.
"Ssh, ssh, just accept it, Nana," Momo says, hugging her sister's head. It seems to lower Nana's defenses somewhat, and combined with the Principal stroking her tail, she loudly orgasms on his dick. Her little body goes limp as the Principal implants his seed inside her as well.
And at that moment, Lala comes walking in. The busty, equally pink-haired oldest sister, and crown princess of Deviluke. "Momo?! Nana?! Principal?!" she exclaims, completely flabbergasted.
The principal wastes no moment, pulls her to the bed, and then pulls her panties down. "Wait, no! I don't understand! Rito, help me! He-" Her speech is cut off by the Principal's big dick entering her. He immediately begins passionately fucking her, and little moans start slipping out of her mouth.
"Seems all three Deviluke sisters are weak against cock, eh? Muhyoo!"
Momo chuckles, while Nana just watches her sister getting raped. "No worries, Lala...it'll feel good...soon..." she says, out of energy.
Given how Lala quickly gives up her struggle, both her sister and the Principal are right. "B-but I love Rito...Rito...ooh...I'm sorry...." Lala sputters while her moans start increasing. Her big breasts swing back and forth as the principal keeps pounding her in her pussy from behind, and she grips the pillow in front of her and puts it against her mouth to muffle herself. At least, until her entire body shivers from pleasure soon enough.
"Ooh? Already cumming? You must be the quite the slut, Lala!" the Principal gloats. Lala only responds by shaking her head.
But not ten minutes later, he is on top of her, while both are completely naked. There she is, in Rito's house, getting fucked by the obese principal of her school, kissing him passionately. She clings her legs around him, grabs his strong back and lets herself get fucked into the bed. It is true baby-making sex. The princess of Deviluke, getting conquered in a way befitting the True King of the Universe. Momo is watching it, content with knowing she made the right choice this time. And in the end, she joins in again too, as all three royal sisters lick his middle-aged cock in obedience.
From there on, his conquest begins in earnest. Every girl that used to be in Rito's harem, falls in an instant once the Principal rams his cock into them.
Risa, Yui and Run
Yami and Tearju
The stuck-up and prude Kotegawa Yui? Moaning like a whore whenever her ass gets slapped as the Principal rapes her right in a classroom on top of her desk. His stinking breath, his sweaty body, this whole situation - in the end, for all her attitude, her body doesn't believe in her own lies. It loves being bred and dominated like this. In the end, she is naked in the classroom on top of the Principal, riding the cock of a man older than her father, while he grabs and fondles her big breasts. Impregnated instantly once he comes inside her.
Tearju Lunatique? Yami's mother? He already conquered Yami, so having a foursome with Yami, Tearju and the slutty nurse Mikado is easily done. Yami and Mikado lick his fat body as he rams his cock inside the shy Tearju, while her massive breasts shine in the sunlight from sweat. The Principal is going to make damn sure both mother and daughter become pregnant from his seed - and once they have their big pregnant bellies, he'll fuck them again, of course. He gets a taste of his future plans already when he alternatively fucks Yami and Tearju on top of each other, while Yami is kissing her mother. And of course, he doesn't leave Mikado out either, railing her on a hospital bed, mating pressing her with all his might while her huuuge breasts jiggle back and forth.
Kirisaki Kyouko and Momioko Risa? Schoolgirl sluts already, easymode. Takes them to a love hotel and gives them the best adult cock they ever had. Without a rubber this time, of course. Fucking oji-sans is normal for them, but even they can't resist the sheer bestial lust behind this one. He keeps going until they pass out and they are good and pregnant.
Kurosaki Mea? Always the seductive brat. He turned the tables on her in the pool, though. Water splashes around them like crazy as she clings to his body, riding his thick cock with all the strength in her little body. Hearts are in her eyes, similar to Momo, as her horny fantasies become reality as well. And much like the others, she has a nice baby in her belly after that encounter too. He knew Nemesis was watching too...he'd just take care of her later.
Oshizu and Mikado
Kyouko, Haruna and Mea
And finally, of course, the shy, adorable Haruna. Rito's first great love. And a girl he still hasn't given a clear answer too, because of course. Why would you expect Rito to do anything? Well, too bad, Rito. Because the shy girl is cutely moaning as a big cock is pumping inside her now. Inside her little bedroom, full of stuffed animals. Surrounded by family pictures. Sorry, Haruna's dad, your daughter is a middle-aged man's cocksleeve now! Her body is thoroughly fucked and bred by the obese, sweaty pervert, and she loves it. The principal moving on a submissive girl like her was like putting a baby seal in front of an orca. Devoured in an instant. The cute puffy lips of her teenage vagina now have a thick pole of meat ram between them again and again, while tears fall from her cheeks at the pleasure she was experiencing despite the betrayal of her feelings. Principal takes his time with her too - for a week, he does nothing but have baby-making sex with her. And he makes a video of it too, that he sends to Rito. It is enough to pull him out of his slump. But it is too little, too late. Haruna, and the rest of his harem, are now the property of the Principal. The next King of the Universe.
And as is typical for Rito, when faced with all that, he just ran. Like the wuss he is.
*Six months later*
The Principal is lying on a big bed. Stars can be seen from outside the window. What a turn his life had taken. Half a year ago, he was just a high school principal. Now, he is in a huge space freighter. Leading a massive nation, getting respect everywhere, and making people fear him. Even Lala's father accepted him as his successor (and probably also to make sure to get away with his wife before he could corrupt her, too). He is good at his new role too - he has a background in this kind of stuff, after all.
Though his style of governance has some effects on earth as well. For one, other middle-aged men followed his example and conquer girls everywhere. Mikan's little loli friends, Haruna's friends, Oshizu, Run, Saki, hell, pretty much every girl that he didn't fuck end up in the beds of oji-sans as well. It became the new and legal norm. An amusing development.
But the best thing, of course, is having his own harem. Young girls, hot teenagers, adult ladies... girls of every shape and size are surrounding him. All with big pregnant bellies. Especially the three Deviluke sisters are eye-catching, wearing sexy bridal lingerie. They are his official wives, after all, not just concubines. And they are horny and getting ready for another love-making session. But they seem to have a surprise today as well. Lala seems to get a signal, and she happily hops out the door. Only to come back later with a new girl on a leash! A big-breasted orange-haired beauty, who looks very shy and demure. One that looks...kind of familiar?
"Yes, master! This is Yuusaki Riko - Rito's female form! I used this invention to turn him into a girl again..." Lala explains, "...permanently, this time," she follows up, as the completely demolished pieces of one of her inventions fall out of her hands.
"Lala...please, come to your senses..." Riko squeaks with tears in her eyes. But Lala just rubs her pregnant belly. "Rito - or Riko, is fully female now, in every biological way possible," she says, ignoring him.
"Muhyooo! That's interesting. Well, there's a first time for everything...let's test if you're right!" the Principal says excitedly.
Riko stares in horror as the Principal stands up, and the shadow of his cock falls over her. Ready to impregnate her. She looks beggingly around the room, but all her former friends are just eagerly awaiting what is coming.
"No! You gotta be kidding me! Noo! Noooooooooo!"
And lots of moans were heard from that room that night...
TRUE ENDING
Riko
