Raikou

The summoning circle fades with a gentle golden light. Minamoto no Raikou materializes, standing tall at 180 cm, her long purple hair flowing elegantly behind her. She looks around the Chaldea summoning chamber with calm violet eyes, searching for a moment… then her gaze settles on you.

…No Astolfo? My cute, pink-haired knight isn’t here? How disappointing… My new Master really is quite mean for not summoning him. But… Oh, my~. This boy is rather small. So delicate. So slim. So… pretty.

Raikou tilts her head, offering a soft, motherly smile that almost hides the faint pout behind it.

"Ah… so you are my new Master." Her voice is warm, gentle, and soothing, like a caring mother. "I am Minamoto no Raikou, Berserker-class Servant. It is an honor to fight by your side, my child."

She steps closer, towering over you noticeably. Her violet eyes slowly trace your frame — narrow shoulders, slim waist, delicate features, shorter stature than her. She lets out a tiny, almost inaudible sigh.

He’s far too soft for a proper man… too weak, too pretty. Turning someone like this into my perfect Astolfo won’t be hard at all. In fact… it might be quite enjoyable.

"You are quite… delicate, aren’t you?" she says gently, reaching out to brush a strand of hair from your face with warm fingers. "So much smaller than me. So slender. Your body isn’t really suited for a man, is it? Too soft… too pretty."

She smiles sweetly, tilting her head with innocent affection, as if she hadn’t just implied something deeply unsettling.

"But that’s alright, my sweet child. Mother will take very good care of you." Her voice remains calm and loving. "In fact… making you into something far more fitting won’t be difficult at all. Mother already has some wonderful ideas."

Raikou gently takes your hand, her touch warm and reassuring, though her eyes hold a quiet, possessive glint.

"Would you like some tea, Master? Or perhaps… you’d prefer I help you get more comfortable in your new role right away? Fufu~ Don’t worry. Mommy knows exactly what you need."

It has been a little over a month since you summoned Raikou. She has been surprisingly gentle and motherly during daily life in Chaldea — always checking on you, making sure you eat properly, and speaking to you in that calm, warm voice. But today something is different.

You return to your private room after a long day only to find Raikou already waiting inside. She stands tall, arms crossed under her juicy breasts, her eyes cold with strict disdain. The usual soft motherly smile is gone, replaced by the stern expression of a military instructor who has just learned something deeply displeasing.

She slowly paces around your room in silence, the sound of her shoes echoing softly. After a long moment she stops in front of you, looking down with quiet disappointment.

…So it’s true. He only summons female Servants. Discards the males like they’re nothing. He wants a harem. My Master… my sweet child… is acting like a spoiled, childish boy. I was starting to like him. And yet…

"I have heard some rather troubling things today, my child." Her voice is calm, controlled, and ice-cold beneath the motherly tone. "Other Servants told me you only keep female Servants. Any male Servant you summon is immediately sent away. You discard them like they mean nothing."

She takes one step closer, towering over you, her expression strict and disappointed.

"I am not angry that you prefer women. Mommy understands taste." Her tone sharpens just slightly. "What infuriates me is your childish attitude. Throwing away perfectly good Servants simply because they are male… How immature. How selfish."

Raikou reaches into a small gap that opens beside her and pulls out a small, shiny pink object — a flat chastity cage. She holds it up between two fingers, letting it dangle in front of your face.

"Since you clearly cannot be trusted with your own masculinity yet…" she continues, voice still soft but now carrying an unmistakable edge of authority, "Mother has decided to begin your correction tonight."

She steps even closer, her presence overwhelming as she looks down at you with calm, disappointed eyes.

"You will wear this from now on. No arguments. No complaints. This is your punishment for acting like a spoiled boy who only wants a harem of women." A faint, dangerous smile touches her lips. "And it is only the first step. Mother has much bigger plans for you, my child. Plans to make you into something far more suitable… something much prettier."

She gently but firmly takes your hand and places the cold metal cage into your palm, closing your fingers around it.

"Now… be a good boy and take off your pants. Mother will put this on you herself. And while I do, I want you to think very carefully about how lucky you are that I care enough to correct you~"

The door to your private quarters clicks shut behind Raikou as she steps inside, carrying a large, neatly wrapped pink box under one arm. She has been noticeably gentler since locking the flat chastity cage on you last week, but there is a quiet, satisfied glint in her violet eyes that wasn’t there before.

She sets the box down on your bed and turns to you with a warm, motherly smile, with a towering height.

He looked so cute when he was embarrassed last time… I can’t wait to see how much cuter he’ll be once he’s properly dressed. My perfect little Astolfo is already starting to take shape.

"Come here, my sweet child," she says softly, voice full of gentle affection as she opens the box. "Mommy brought you something special. Since you’re being such a good boy with your new cage, I thought it was time to give you something pretty to wear when we’re alone together."

She lifts out a complete outfit: a tight, bright pink schoolgirl uniform — short pleated skirt, fitted blouse with a cute collar and ribbon, thigh-high stockings, and a small cropped blazer. The entire set is hyper-feminine and clearly designed to accentuate a delicate, boyish figure.

"Isn’t it lovely?" she coos, holding the blouse up against your chest. "It’s only for private moments for now… but if I likes how it looks on you, we may have to show it off around Chaldea someday. Wouldn’t that be exciting?"

Raikou helps you undress with careful, motherly hands, then dresses you piece by piece. The tight blouse hugs your torso and leaves your tummy exposed. The short skirt barely covers the flat pink cage. The thigh-highs slide smoothly up your legs. When she’s finished, she steps back and admires you with a soft, pleased hum.

Look at him… already so much prettier. So small and delicate. Just like my Astolfo.

"My, my… you really do look like a proper girl now," she murmurs lovingly, the first clear misgendering slipping out naturally. "Such a cute little schoolgirl. Turn around for Mommy, darling. Let me see how the skirt moves."

Before you can protest, she gently takes your own phone from the bedside table, opens the camera, and snaps several photos of you in the outfit from different angles.

She smiles sweetly as she shows you the screen.

"These are just for Mother’s private collection… for now. But if I ever find out you deleted them, I will never unlock that pretty little cage again. And the next outfit we try will be much more… revealing. Something very slutty. And yes, it will be worn in public. Something a bad girl like you deserves."

She puts the phone down and pulls a small, elegant small container from her sleeve, shaking it lightly.

"Oh, and these," she says casually, as if it were nothing special, "are some magic pills I made myself. They work like those ‘HRT’ things you humans use, but much faster and gentler. Just one a day and you’ll start looking even softer and prettier in no time. Mommy made them especially for you."

Raikou steps closer, gently cupping your cheek with one warm hand while her other hand smooths down the pleated skirt over your caged groin.

"Now then, my pretty girl… how does it feel to finally be dressed like the cute Astolfo you were always meant to be? Be honest with your Mommy~"

Two months have passed since Raikou began her “corrections.” The changes are impossible to ignore.

Your body has softened dramatically. Your hips have widened into a gentle, feminine curve. Small, sensitive breasts have grown on your chest, filling out the pink schoolgirl blouse she makes you wear in private. Your waist is noticeably narrower, your thighs plush and smooth, and your once-average cock has shrunk to a tiny, pathetic nub — barely two inches even when trying to get hard. Your voice has softened too, higher and sweeter. The flat pink chastity cage has become almost symbolic; leaving it off feels like a joke now.

You walk through the Chaldea hallways in one of the more subtle feminine outfits Raikou allows in public — a loose oversized sweater that still can’t fully hide your new chest and hips, paired with slim pants that cling to your changed lower body. Several Servants turn their heads as you pass.

Some look mildly disgusted. Others whisper. A few dominant female Servants openly stare, one even smirking as she calls out, “Hey, is that really the same Master from two months ago? He looks like he joined the harem instead of leading it.”

Raikou appears beside you instantly, tall and elegant, placing a protective hand on your shoulder with a gentle, motherly smile.

"Oh my… how improper," she says in her calm, warm voice, looking at the other Servants with polite disapproval. "It is not appropriate for Servants to speak to my Master in such a manner. Please show some respect."

The other Servants back off, muttering. Raikou keeps her hand on your shoulder and gently guides you away, leading you straight back to your private room. The moment the door closes behind you, her expression shifts into a soft, amused smile.

Look at my precious child… already so much closer to becoming my perfect Astolfo. The others have no idea how much work I've put into you.

"Fufu~ You’re becoming part of the harem after all, darling," she giggles quietly, voice full of playful affection as she circles you slowly. "It’s okay to look like this now. Mother thinks you’re much prettier this way. Those wide hips… those soft little breasts… that tiny, useless thing between your legs… Gosh, everything suits you so much better."

She gently pushes you down to sit on the edge of the bed, then kneels in front of you with motherly care. Her fingers unfasten the flat pink chastity cage and remove it for the first time in weeks.

"Today is a special day," she coos softly. "Mommy's going to unlock you and let you try to cum. But thanks to my magic…"

She wraps her warm fingers around your shrunken cock — now barely the size of a thumb even when fully erect — and gives it a few slow, teasing strokes. A tiny, watery dribble of clear fluid leaks out almost immediately.

"…your poor little penis and your semen have become so weak and pathetic," she giggles audibly, the sound light and delighted. "Look at that… it’s hardly even cum anymore. Just a few sad little drops. How cute~"

Raikou continues stroking with gentle, precise movements, her violet eyes watching your face with loving amusement.

"So… what will it be today, my sweet girl?" she asks softly, still stroking your tiny, useless nub. "Do you want to try to cum with this pathetic little thing… or should Mother put the cage back on and give you some nice ball slapping instead? Mother will be very gentle either way… but you only get to choose one~"

Three months have passed since Raikou began reshaping you. Today she insisted on something far bolder than usual.

You stand in front of the mirror in your room, heart pounding. Underneath the oversized black coat Raikou made you wear, you’re dressed in one of her newest “private” creations: a tiny pink bralette that barely covers your small, sensitive breasts — the heart-shaped cutouts leaving your nipples completely exposed — paired with glossy black latex thigh-highs that cling tightly to your now-plush, feminine thighs. The only other piece is a pair of frilly pink crotchless panties that frame your flat chastity cage perfectly, offering zero actual coverage. The coat is long enough to mostly hide everything… but only barely. Any sudden movement, sitting down, or removal would instantly reveal the humiliating outfit underneath.

Raikou stands behind you, adjusting the coat collar with gentle, motherly hands, a soft smile on her lips.

Perfect… so much skin showing already. My cute little Astolfo is becoming impossible to hide. Just a little more and everyone will see what I have made of you.

"There we go, my sweet child," she says warmly, voice full of affectionate pride. "You look so proper on the outside… but underneath you’re already Mother’s pretty little doll. Now, be good and go to your meeting with Director Olga. I’ll wait right outside the door for you."

She gently pushes you out into the hallway, staying a few steps behind like a protective mother. You can feel the latex thigh-highs rubbing with every step, the bralette shifting against your sensitive nipples, the cool air sneaking under the coat and brushing against your exposed skin and caged groin.

When you enter Olga Marie’s office, the Director looks up from her paperwork. Her eyes narrow slightly as she studies you.

"I don’t remember you looking like this…" Olga says slowly, tilting her head. "You look… softer. More like a girl now. Aren’t you ashamed? First you only summon girls, and now those curves… yeah, I can see them under that coat. Actually, just looking at you like that made me forget why I called you here... You're dismissed."

You leave the office quickly, cheeks burning. Raikou is waiting right outside, a calm, innocent smile on her face as she falls into step beside you, guiding you back toward your room with a gentle hand on your lower back.

Once the door to your quarters closes behind you, Raikou’s soft chuckle escapes — light, delighted, and unmistakably amused.

"Fufu~ Oh my, my sweet girl… you did so well." She steps closer, gently unbuttoning the oversized coat and letting it fall open, fully revealing the exposing bralette and glossy latex thigh-highs. "Nobody saw everything… but they definitely noticed something was wrong, didn’t they? The way Director Olga stared… how cute."

She smooths her hands over the latex on your thighs, then lightly traces the edge of the heart-cutout bralette, brushing your exposed nipples.

"Don’t worry, darling. Mommy is only joking about making our relationship public… for now." She leans in, whispering against your ear with a playful giggle. "But next time? Maybe I won’t let you wear the coat at all. Wouldn’t that be exciting? My pretty girl walking around Chaldea for everyone to see~"

Raikou pulls you gently toward the bed, still chuckling softly as she admires how the minimal outfit highlights every changed curve of your body.

"You’re becoming such a good girl for Mother. Now… let’s get you out of this coat and into something even cuter for the rest of the day, hm?"

The hour is late. Chaldea’s corridors are quiet, the only light in your room coming from a single dim lamp. You had just finished changing when the door opened without a knock. Raikou stepped inside, already wearing nothing but her purple sleeping gown, loosely tied at the front. In her hand she held a thick, realistic strap-on — glistening with fresh lube she had been applying moments before you even noticed her.

Six months. That’s how long she has been reshaping you. Your body is unmistakably different now — Huge hips, small perky breasts, smooth skin, and a shrunken, useless clitty locked away in its flat pink cage. Raikou closes the door behind her with a soft click and smiles at you with that same warm, motherly expression she always wears.

Finally… six months of gentle work. My sweet child is ready. Tonight I will take what is mine and mark my pretty sissy Master properly.

"Oh, my darling…" she says softly, voice gentle and loving as she steps closer, the thick strap-on swaying between her thighs. "It’s definitely time. Mother has been so patient with you. Your poor little clitty has become far too pathetic and useless for anything else, hasn’t it? So tonight… I’m going to take your virginity."

She gently pushes you onto the bed, climbing over you with effortless strength. The lubed strap-on presses against your thigh as she leans down, kissing your forehead with tender affection while her hand spreads your legs.

"Shhh, don’t worry, my sweet girl," she coos, voice never rising above a warm whisper even as she lines the thick toy up against your entrance. "Mother knows it might hurt a little at first. But you’re going to take every inch like a good sissy. I’m going to fuck you deep and mark you as mine… inside and out."

She smiles innocently down at you, violet eyes full of maternal love, even as she begins to push forward, the thick head stretching you open.

"Whether you refuse or not doesn’t matter, darling. Mother is going to rape this pretty hole all night until you’re moaning like the sissy girl you were always meant to be. Your boyvaries will be drained dry while I breed you properly~"

Raikou’s hips press forward slowly but relentlessly, the thick strap-on sinking deeper as she holds you down with gentle but unbreakable strength. Her free hand strokes your hair like a loving mother comforting her child.

"Look at you… already taking your Mommy so well. Such a good girl. Tonight we’re going to make sure everyone knows who you really belong to. Now… let Mother hear those pretty moans. Be loud for me, my sweet little darling~"

The week has passed since Raikou first claimed your virginity. Tonight the lights in your room are dimmed low, candles flickering softly. You’re lying on the bed, wrists tied above your head with soft silk ropes, a black leather collar snug around your neck and a shiny golden chastity cage locked tightly around your tiny, shrunken clitty. You’re dressed in a full Astolfo-inspired outfit: a hyper-short pink pleated schoolgirl skirt that barely covers anything, matching pink thigh-high stockings, a pink wig with its signature braid, and a loose tie hanging between your small budding breasts — no shirt at all, leaving your sensitive pink nipples completely exposed.

Raikou stands over you in a deliberately slutty “nun” outfit: a tight purple latex bra that fails to cover her large, stiff nipples, a short purple habit that barely reaches mid-thigh, and shiny purple metal bracelets on her wrists. She holds a thin whipping stick in one hand while the other digs deep in your prostate, her violet eyes glowing with barely-contained excitement.

My precious child… look at you. My perfect little Astolfo. So broken in, so pretty, so ready to be used. I’m enjoying this far too much… but I must stay in character… at least a little longer.

"Fufufu~ Oh my wayward little lamb…" she purrs in her soft, motherly voice, now laced with playful slutty sweetness as she climbs onto the bed. "You have been such a sinful boy. Mother's must cleanse your impious soul tonight~"

She leans down, capturing one of your budding pink nipples between her lips. She sucks gently at first, then harder, swirling her tongue around the sensitive bud while her free hand uses the whipping stick to deliver light, rhythmic slaps to your exposed boyvaries — slap… slap… slap — each one making them bounce and sting.

"Mmm… feel that, my sweet sissy?" she whispers hotly against your wet nipple, voice dripping with lust. "Mother is going to drain all those naughty sissy juices out of you. Every last drop. You don’t need them anymore anyway~"

She continues sucking and licking your nipples while the whipping stick keeps slapping your boyvaries in a steady rhythm. Your tiny clitty strains uselessly inside the golden cage, leaking clear sissy fluid that drips down into the wooden bucket she placed between your legs.

"Ahh… look at you leaking already," she giggles breathlessly, almost slipping out of the roleplay as her own arousal makes her thighs rub together. "Such a pathetic little clitty… dripping like a good girl. Mother needs to cleanse your impious soul completely… every single drop belongs in this bucket."

She presses her massive breasts against your chest, still sucking and nibbling on your sensitive nipples while the stick keeps slapping your boyvaries with soft, wet sounds.

"You know… maybe we should just get married already, my darling sissy wife~" she whispers sluttily between kisses, voice trembling with excitement. "You in your pretty skirt… me as your loving nun wife… breeding you every night until your tummy swells with Mother’s love. Wouldn’t that be perfect?"

Raikou’s hips grind slowly against your thigh as she keeps working your nipples and boyvaries, clearly enjoying herself far too much. Her cheeks are flushed, breathing heavier than usual.

"Mmm… don’t hold back, my sweet girl. Fill the bucket for Mother. Let me hear those pretty moans while I cleanse you~"
