vinyl and octavia had become very good friends over the years but one day octavia had shared a very very bad secret with pinkie pie about vinyl. vinyl had a very very weak bladder so she had to wear pull ups to most of her gigs but lately she has been needing diapers to sleep vinyl couldn't believe octavia would do such a thing. vinyl got a book of transformation spells and found one she would like to use on tavi.
vinyl giggled like a filly "this should be fun"
octavia soon walked in "hey vinyl you still mad"
vinyl said "a little but i think i will be fine"
octavia sighed "good"
vinyl gave a smug smile "anyway I'm out of diapers I'm wondering if you could help me"
octavia agreed "oh of course"
vinyl's horn glowed "great!"
octavia looked worried "wait what are you"
vinyl blasts octavia with magic
octavias body turns soft and cushie when the transformation was complete she was a huge pack of large diapers
vinyl said surprised "wow you turned out thick"
octavia mumbled "mmph mmp (vinyl why did you do this to me)"
vinyl examined the diapers "looks like you can see but you don't have a mouth hm" she opens pack and takes out diaper "wow your eyes are on the front of this one"
"mmph mm hmm (please vinyl I'm sorry)"
vinyl unfolded octavia and taped her around her flank tight enough to make sure she wouldn't fall off
vinyl giggled and said "your a very thick diaper i could wear you for hours without a change"
"mmph (please vinyl i don't want to be a diaper)"
vinyls throat felt dry "hm i could use a drink" vinyl got on phone and calls octavias friend clef "ah this should be fun"
octavia mumbled "mmph (why)"
clef was a young mare the youngest in octavias group she looked a lot like octavia but with a pink coat instead of grey and she was a unicorn when she showed up she noticed that vinyl was wearing a diaper with octavias cutie mark on it
clef entered the home "oh hey vinyl how are you"
"good" she said well she cuts off clefs tail and mane*
clef yelled "what the heck vinyl"
vinyl turned clefs tail into a bottle and her mane into a pacifier "there we go"
clef; w-what
vinyl said "now i can't have you talking to everyone about this" she uses her magic and turns clef into a pack of pull ups "hm" she takes off octavia "i think i should use these first"
"mmph (please no)"
vinyl smiled "i knew not using the bathroom all day would pay off" she grunts as the back of her new pull up bulged out
octavia looked as the pull up that used to be her friend clef got filled with mess and urine as soon as vinyl was done she sat on the couch and levitated the bottle and pacifier over
vinyl licks her lips "mm chocolate milk" she drinks the bottle
octavia looks away
vinyl opens the spell book "hm ah the diaper curse is permanent looks like your going to be diapers for a long time tavi" her stomachstomach grumbles again "well time to potty again" vinyl grunts and messes clef more
clef whimpers
vinyl smiles "time for a change" she lays down "so squishy" vinyl takes off the soiled pull up and throws it away
octavia had never felt more hatred to a pony then she did to vinyl at that point she had just turned her friend clef into a pull up and using her
vinyl finishes putting pull up on
almost an hour later
vinyl turns clef back "I've had my fun"
clef was very angry "vinyl i can't believe you I'm calling the guards" clefs eyes widened as if she was in a trance
vinyl smiled and said "now you are my nanny you change me and let me watch any movie i want you let me use my spells on anyone you see and you wear diapers that i tell you to wear"
clef nods as the hypnosis sinks in
vinyl smiled "good"
clefs eyes go back to normal "vinyl my little one wheres your diaper"
vinyl said like a foal "im sowwy nana i took it off"
clef sighed "your a very naughty girl" she sees octavia "there it is"
"MPPH! (no clef its me octavia)"
"now lay down sweetie" said the nanny that used to be clef
vinyl said "yes nana" she lays down
clef lifts vinyl's legs and lays her on octavia and tapes her shut
octavia couldn't believe it she was going to be a little foals diaper her friend had no intention on turning her back
vinyl uses spell to make clefs mane and tail grow back well she is not paying attention
clef doesn't notice the change "now keep this one on little one"
vinyl protested "i nu little I'm a big girl"
clef said "yes you are little one" she picks up pacifier and puts it in vinyls mouth
vinyl sucks on the pacifier
clef gave out a small aww
octavia didn't know when but she knew vinyl was going to use her she was very very worried about it almost an hour later vinyl and clef were watching a scary movie octaivia knew this movie. vinyl couldn't get through it without wetting herself
vinyl was laying her head on clefs side
clef was wearing one of vinyl's old diapers "this doesn't look like a good movie for a foal"
vinyl gave puppy dog eyes "please nana"
clef sighed and pressed play
during the movie octavia knew she was going to be used
vinyl said "nana i have to go potty"
clef just said "well you know what to do"
viny agreed "yes nana" she wet self
"mmph (ewww)"
vinyl and clef watched the movie until the scary part when vinyl had gotten so scared she messed herself octavia felt it all after the movie vinyl needed a change very badly.
clef noticed a very bad smell and looked at vinyl "looks like my little filly needs a change"
vinyl pushed her hoof on octavia "so squishy"
clef picked up vinyl and layed her down
octavia felt the entire change the worst part was being balled up and thrown away she was put back onto vinyl.
vinyl smiled "thank you nana"
clef said well filling bottle with milk "time for dinner"
vinyl smiled "yay milky time"
clef fed vinyl her bottle well octavia mumbled
"mmph (at least I'm clean now)"
clef levitated a footed sleeper over "time for you pjs"
vinyl yawned and said "yay"
clef slid the sleeper over vinyl and octavia, octavia didn't like being stuffed in a sleeper. vinyl loved the sleeper on the other hand she thought it was very comfy.
vinyl said in a baby like tone "nana i tired"
clef smiled and said "alright lets get you to bed"
clef carried vinyl up to her room and laid her in bed. the next day vinyl forgot she had turned tavi into a diaper she soon remembered when her diaper was blushing. she wanted to be able to see octavia again so she used the last three diapers to take a little bit of octavia they had in them to remake octavia. unfortunately she didn't have enough to work with and octavia formed into a filly she did keep the part of octaivia in the diaper she was wearing
octavia yelled at vinyl "vinyl why did you do that!"
vinyl replied "you told every pony my secret and guess what" she said smugly
"what" the gray foal asked very worried
vinyl told her "this diaper I'm wearing has the rest of your age in it until i use it, it stays a diaper"
she yelled at vinyl "give me my age!"
vinyl thought for a minute "hm alright"
octavia yelled "yay"
vinyl sat on octavia
octavia yelled again "HEY GET OFF"
vinyl said having a cocky tone in her voice "what you got your age back" vinyl grunted octavia felt vinyls diaper bulge out a little
"vinyl what are you... NO PLEASE I NEED MY AGE i don't want to grow up again" octavia yelled
vinyl filled her diaper well sitting on octavia the last chance octavia had to get back to normal was gone. octavia felt the diaper squish against her. vinyl smiled she had her revenge on octavia was complete octavia cried and octavia got off.
clef soon walked in "oh who is this"
vinyl's horn glowed "thats my little sister tavi scratch she has to wear diapers day and night no matter what she says or how old she gets"
"oh of course" she looked at octavia "tavi scratch where is your diaper"
octavia protested "i don't need diapers"
"thats what you always say" clef picks up octavia and takes her to changing table, "now its time to get you a diaper"
octavia kicked her legs trying to keep from being put in a diaper but she wasn't strong enough to keep it from happening. clef soon finished taping the diaper on octaiva and set her on the ground octavia whimpered. octavia and vinyl weren't about to be out of diapers for a very very long time but they didn't need to worry octavia was glad to be back to a pony. soon her cutie mark appeared a pink pacifier.
