You don't know why you took the swimsuit, but it seemed to call you. You held it up and stared at it. You recognized it from various anime, it is a small, blue, one piece swimsuit: a sukumizu, or "school swimsuit". There is a white patch on the front, across where a girls breasts would be, with japanese writing on it (though you have no idea what it says). Suddenly, you have a perverted thought...you wanted to try on the swimsuit. It was much too small for you, but something was compelling you to at least try and put it on. You quickly run to a restroom, swimsuit in hand.
After looking around to ensure nobody was around, you duck into a stall and remove your clothes. You get somewhat aroused as you stare at the swimsuit, looking like it came straight out of an anime. You imagine how cute a girl would look wearing this. Pushing those thoughts aside, you stretch open the top and move your hairy legs into the tiny swimsuit. To nobodys surprise, it doesn't fit. You sigh sadly, before pulling off the swimsuit from your legs
"*sigh*, its a shame this thing doesn't fit. But what did I expect"
Then you hear a girls voice say to you
"hee hee hee, upset, are you? Maybe I can help you out, pervert~"
You look up, and see the face of a cute girl peering over the stalls. She had an adorable, girlish face with pink eyes and heart shaped pupils. He cotton candy pink hair was tied up into a pair of cute twintails.
"AAAAAAHHHHH, What are you doing in here!" You say, attempting to cover your naked body with your hands.
"Better question is what are YOU doing in here, Mr. Pervert. This is the girls washroom"
Your eyes go wide and you burst out of the stall, theres not a urinal in sight, and its significantly cleaner than the boys washroom. You accidently entered the girls washroom! You then look at the source of the voice. Standing in front of you is a tiny, petite little girl. She looks to be about 12 years old or so. She is wearing a frilly pink maids dress, knee high socks and some pink mary janes. She sways in place, looking absolutely adorable.
"You looked upset, mister? Maybe I can help you fit the swimsuit" She thinks for a moment, before looking back up at your naked body with a smile "Yeah, thats what I'll do~.". She pulls out a pink, plastic wand with a sparkly heart at its tip.
"N-no, I need to get out of here. Get out of the way, shorty" You say, desperate to get out, as you pick up your clothes.
The girl puffs up her cheeks and pouts cutely, her heart shaped pupils almost glowing with rage.
"Shorty! Shorty! I'll show you a shorty" she says, before waving her plastic wand in the air. To your surprise, a small beam of light shoots out and hits you in the chest. You go to yell at the kid before you feel something strange. Your body begins to shrink, growing smaller and smaller as you see yourself reaching closer to eye level with the little girl. The shrinking stops, and soon you are only an inch or two taller than the girl. You scream
"AHHHHHHH, WHAT DID YOU DO TO ME! WHY AM I SO SHORT! CHANGE ME BACK YOU LITTLE..." You scream at the girl
"Kyouko, my names Kyouko. And don't you worry about your height, boys love short girls~! Hmmmm, What to do next..." She says, then she shoots another beam at you. Now, all your body hair falls off, everywhere except for your head. Your skin is now significantly smoother.
"Thats a good start. Lets work on the face first. First your hair~" She says, before hitting you with another beam. Your hair turns a dark black, and grows longer and longer, reaching midway down you back. It becomes very straight and clean. "Then your eyes~" Your eyes now change color, becoming something special. One eye turns green while the other turns blue, giving you different colored eyes. They also begin to look a lot more asian. "Give you a little girly mouth~" You lips tingle, as they plump up, becoming soft and kissable. Your mouth becomes smaller and daintier overall. "And some finishing touches" Your face rounds out, becoming soft and feminine. Your nose shrinks becoming tinier and girlier. Soon, you have the face of a cute japanese girl.
"What are you doing! Whats with the wa-" You turn and see your face in the mirror "AAAAHHHH, why do I have a girl face!"
"Oh no, that voice won't do at all" She swishes the wand, and your screams become higher pitched
"No....not the voice" You say, your voice is now so high and squeaky. It would be absolutely adorable if it weren't coming from your own body. Suddenly, the girls walks up to you, holding the swimsuit.
"It should fit better now~ You should put it on, or else~" She says with a cute smile. Not wanting to anger the magical girl, you put on the swimsuit. You are able to actually wear it now, but its actually a bit loose on your diminished frame.
"Its...uhhhh....a bit small" You say, your cute voice making you blush
"Duhhhh, you aren't finished changing yet" She walks up to you and pokes your chest. "You're missing a girls most important feature". Your chest begins to tingle, and you see the flesh begin to push out, you know whats happening: You're growing tits! The breasts grow out larger and larger, now at a B cup, they begin to strain the swimsuit. They continue to expand, becoming bouncier and larger, now C cups. The nipples are now a lot more sensitive, and you let out a soft feminine moan as they push against the fabric of the swimsuit. Finally, the swimsuit now fits tight around you chest as a pair of DD tits stretch it to its limit, you look down and see your beautiful cleavage blocking the view of your legs and feet. You step forward slightly, and the breasts bounce and jiggle.
Kyouko shoots you again in the hips and stomach. Your stomach flattens, becoming smooth and girly, and your waist pinches inwards. Your tight swimsuit now shows off your girly stomach and curvy waist. You feel you butt become very plump and girly, once again bouncing with every move you make. Kyouko wants to turn you into a short curvy and busty japanese girl. You have to get her to stop! You kneel before her, as your hips begin to push outwards, tightening the swimsuit around your lower half.
"Please Kyouko, just change me back! I don't want to be this short japanese girl, please!" You say, tears flowing down your soft girly face.
"Anything? Hmmmm~ Oh, I know!" She says with an evil grin. She reaches down and takes off her mary janes, holding her socked foot close to your face. "Lick my feet like the good little girl you are, then I might consider changing you back". You hesitate at first, but obey her commands. You take her tiny socked feet and start licking it all over, and sucking her tiny little toes. The action puts you into a sort of trance and you continue to pleasure her tiny feet. From above you can hear Kyouko moan. "ufufufufu, I love it~ Turning mean boys into sexy girls~ making them submissive sluts~"
As you lick Kyouko's feet, your own begin to change. They become small and dainty. Your nails become perfectly manicured. A pair of white socks appear on your feet and they begin to stretch up your legs. As the socks pass your legs, they become smoother and sexier, growing slightly longer as well. Finally the socks stop at your thighs, which puff up with feminine fat. Finally, your penis goes into your body, becoming a vagina. As you sit there, licking the magical girls feet, you finish your transformation into a swimsuit clad japanese girl. Kyouko removed her foot from your mouth and summons a large mirror in front of you. You gasp. You are short and busty, your DD tits pushing out giving you a beautiful cleavage. You can now see the words written on the swimsuit it says "Yuuko" (You assume this is your new name). Your face is cute and pouty, with long silky hair flowing down. Your hips and butt will sway as you walk. You can't see your feet past your large breasts, but the mirror shows they are clad in silky white thigh highs. You can hardly recognize yourself, you're a total shortstack! A tiny, busty japanese girl. You think to your friends, and how they'd go absolutely crazy over your new body.
"Awwwww Yuuko, you look so pretty!" Kyouko says in Japanese
"Arigatō, shikashi, anata wa watashi o ima modosu koto ga dekimasu ka?(Thanks, but can you change me back now)" You gasp, why did that come out in japanese. You try again. "N-naze watashi wa eigo o hanasenai nodesu ka?(Why can't I speak english)"
Kyouko pouts "Ohhhh, poor little thing. Can't speak english anymore? Well, won't do much good in this country, will you? Goodbye~" She waves the wand one last time, and everything goes bright. Suddenly, you find yourself in a classroom, sitting in a desk. You look down and see you are clad in a standard japanese schoolgirl outfit!
