The nursery was huge for anyone that was already for all ages and not forget pink, as our hero struggles in the demon princess's arms but with her being the size of a doll to the demon princess Lucy it was a zero chance to get out of her grasp, soon she was taken to a changing table which was big, as she was strapped in and her legs lifted up like it was nothing, as Alesia had tried to struggle against her but couldn't soon, her panties were taken off and replace with thickening diapers 3 to be as Alessia's princess parts were wiped, oiled, powdered, and soon the 3 diapers under her legs and taped around her waist all snug as this forced Alessia's legs to spread as our hero blushes but continues to struggle, as the straps were taken off and she was lifted up once more head forced to be on the princess's shoulder and a pacifier with the rubber nipple large enough to cover the whole mouth was forced into Alessia's mouth as our hero blushes once more and tried to spit it out but couldn't as she was taken to a playpen with the playpen bars high up and thick on the parts to make it hard to escape as she didn't know that the princess was actually a queen but growing slowly and was actually not 7 but 20 years old as our hero tried to get out of the playpen when the princess left her to "play" as the playpen had a lot of toys, Holly the demon maid was in the garden taking care of it as another demon was in the castle, that our hero didn't know as she kept trying to escape in the playpen as she kept trying over and over, but soon gave up to think of a plan, as for the other demon, was in the castle and soon came into the door where our hero was as she had 4 arms, and looked very human and her breast were the size of diner plates as she come in with a dress of a navy blue and apron her horns were curved up, as she comes over to the playpen where Alessia was in and looks down smiling as she picks her up like a infant, "hello there little one, you must be the queen's new little one, I'm Milly, mother demon' she said smiling as Alessia blushes and squirms in the demon woman's arms but with all four keeping her from kicking Milly it was no chance, as she was hugged close to her. 'Now let's get you to the library for you baby girl' she said putting Alessia's head over Milly's shoulder as Alessia continues to squirm and wiggle, but couldn't with Milly having a good grip on her as she was taken somewhere through the castle hallway, soon coming to a door with golden letters in capital saying "LIBRARY" on it as the door was large and looked to be made of gold as the carving was similar to the elf kingdom's as Milly opens the door and inside was a library that looked to go in and on, as Milly carried the small knight to a place for kids which Alessie thought was stupid but was put in a what seems to be a chair but had cushions and straps which our hero continues to squirm but couldn't as she was now strapped in this wondering chair with no escape, as Milly with a snap of her finger some mittens were put on our hero's hand to keep her from having a grip on things as Milly founda book for our hero as this book wasn't a normal book but a dream book to anyone who grabs and reads it will be put into a deep sleep, for the dream book would take anyone anywhere as it pleases, which our hero didn't know she picks it up and reads it to pass the time, but soon after reading a right page, she was put into a deep sleep, soon after few moments, Alessia wakes up inside of a gigantic playpen, bars too high to climp out and bars are too close each other to get through them, playpen is filled with adult sized babied toys, playpen itself is inside of a nursery room to take care of the adult sized baby, Alessia, herself is totally naked, hair only on head, nowhere else, Alessia looks at herself and sees she was naked, she blushes a dark red, and looks around to see if there were any clothes as she walks around in the playpen but soon tripped from the soft mattress she was standing on and crawls around to see if she could but found now, but someone outside of the nursery room felt that new baby arrived, she comes behind of the nursery rooms door, there are no doors inside, Alessia can only see walls, but the door is in the wall and it started to open, Alessia looks as she backs away and looks around to see what she could use to fight or hide which she found a huge plushie as she hides behind it since she think was in the monster kingdom, door opened fully and a beautyful succubus, which looks very similiar to the nanny in the inn earlier walked it, she walks over playpen, kneels down on Alessia's eye level and says with sweet voice '' hey there, sweetie, there is no need to hide, i wont hurt you, come here from behind of the plushie... we are nursery of heaven, we take extremely good care of our babies, like they are our own and im the head nanny of this nursery, nice to meet you, baby... wat is your name, baby? can you say your name? '' head nanny smiled at our hero, Alessia peaked out and sees the head nanny thinking it was the innkeeper as she crawls out of her hiding spoke and was confused but decided to ask questions later, "I'm Alessia, I'm 20 years old" she said looking up at the head nanny, as the head nanny was confused about why Alessia was hiding, '' why are you hiding, little Ally? are you without clothes? well, if that's the case, crawl here and I'll get you dressed, I'm sure that crawling on the mattress is very comfy '' nanny said with a sweet and caring voice... the playpen mattress is thick and very comfy, as Allesia blushes at the sudden nickname but crawls over to the head nanny" I thought you were one of the scary people" she said talking about the monster kingdom which got the head nanny to pick her up "awww, baby thought me as a bad person, you poor thing '' nanny stood up, opens playpen, picks Allesia up, cradles in her arms like a baby and tells '' I would never hurt a sweet girl like you, baby... but before giving baby something to wear, she needs a comfy diaper '' nanny carried Allesia over baby changing table which made our hero blush even more as the head nanny lays her down on the taple, takes cloth diaper makes it ready, lifts Allesia's bottom up, brings it under, uses baby oil on her pvt area, closes diaper carefully to not hurt Allesia and finally brings plastic panties over the diaper '' there we go, baby '' then nanny walked over closet opens it and it shows 3 frilly and fluffy baby dresses, yellow, light blue and pink, nanny asks '' which one baby wants? '' the head nanny asked making Allesia blush even more but she pointed to the blue frilly and fluffy baby dress not wanting to wear pink since in the nursery was pink and she hated pink, as nanny took blue frilly and fluffy baby dress, puts others away, brings blue dress with her and helps Allesia get dressed in it, nanny says '' now you are ready for your fun day in here, baby... and you look so adorable in that dress '' nanny says with sweet voice and gives sweet smile, as our hero looks at herself and was blushing hard but soon picked up once more as nanny picks Allesia up, craddles like a baby in her arms, carries back in the playpen, puts on the comfy matress and tells '' baby can go to pway, nanny goes to get you a bottle of yummy milk '' nanny walked over fridge as our hero crawls around in the playpen and looks around to see what she could used to play or a way to escape, nanny opened fridge, takes large bottle for adult sizex baby  Alessia, closes fridge door, brings the bottle of special laxative milk, which makes whoever drinks it, makes them lose bladder control... it will help Alessia to feel more like a baby who cant control her bladder, nanny puts bottle on middle of the playpen, tells '' nanny is needed elsewhere, baby can dwink her bottle once she is hungry '' with baby-talk and left... knowing that she wont think that the bottle makes her like that, but she wont think that nanny did that either, because how sweet she is, as Allesia found coloring stuff and started her plan, as she plans her escape, but what our hero didn't know that the head nanny had a magic seeing through the wall magic to watch over you while she took care of the broken adults being babies room as Allesia was coloring but got hungry in 30 minutes as she crawls over to the big adult size baby bottle of milk as she lift it up and had to use her feet too to hold the bottle of milk as she started to drink it, ast he head nanny smiles knowing how Alessia are holding it and finished bottlefeeding babies, nannies took babies to play in their playpens and started to look after their playing but soon after about an hour, Alessia finished drinking the bottle of milk as she burps and pants but she went back to her plan as head nanny knows she finished the bottle and...'' she has lost the bladder control after she finished that bottle and burbed... soon enough she'll start to pee and mess her only one diaper and plastic panties on her '' said the head nanny in her mind as she holds one of the babies in her arms bottlefeeding them for naptime, a while the magic of the drug started to do it's magic as Alessia's tummy rumbled as she started to poop and pee as she freaks a little bit but goes back to her plan,'' once she finishes messing, soon after the diaper starts to feel uncomfy on her, she will start to tear up... i can feel it coming soon enough '' she said in her mind as the head nanny continued to look after other babies playing and some napping, as for Alessia, she couldn't control her bladder and bowels as she filled the diaper up to that it looked like it was about to burst from any sudden movement, the head nanny knew Alessia had filled her diaper to the point that it would burst but waits for Alessia to cry which would be a while , as for Alessia sees it and felt how uncomfortable but warm it was her diaper as she doesn't move a muscle and soon after what seem to be for hours but was only 20 minutes she started to tear up from the foul smell as head nanny felt it, came inside of the private nursery room, opens playpen and walks over to our hero, nanny kneels down on her eye level and says '' why are you cwying, baby? tell nanny, baby, so nanny can help you '' she said as nanny gave her pet on her head softly, which Alessia blushes hard but knew she had to answer to get rid of the large garment, ' I messy nanny" she said with a disgusted look on her face being very uncomfortable in the overfilled diaper, '' aww, you poor thing, let's go get your diaper changed, baby '' head nanny siad and stood up, picks Alessia up, cradles in arms like a baby, takes pacifier from her pocket, pacifiers nipple is big enough to fill her mouth, nanny brought it closer to her mouth while carried over the baby changing table and tells '' open your mouth, baby, and suck on this '' she siad as Alessia just opens her mouth and starts to suck on the pacifier since not given a choice of how close it was to her mouth as nanny lays our hero down on table, lifts her dress up and sees the mess and pee on there, nanny says '' oh dear me, I have never seen mess this big in here, baby '' nanny opened plastic panties and the diaper after it, lifts Alessia's bottom up and shows her the diaper and plastic panties '' just look at this mess, baby... cloth diaper is not enough for you, even two diapers wont be enough, you are going to need 3 diapers '' nanny threw them away as our hero blushes even more of a dark red of sangria and looks away to not see the full diaper, nanny takes 3 thick looking fresh diapers, opens them, lifts Alessia's bottom up, brings them under, wipes her private area clean, uses baby oil on private area, sprinkles baby powder on private area and closes all 3 diapers on, nanny helps Alessia to sit up and says '' now you have plenty of protection, baby"' Alesia's bottom looks huge now and it lifts her dress from behind, and buttons it close as head nanny picked her up, '' its time for baby to take nap '' nanny picks Alessia up, craddles like a baby, carries over crip and starts to rock her to get her to fall asleep, Alessia started to feel sleepy as she yawns and sucks on the pacifier in her mouth, nanny continues to rock her to sleep, while says with sweet voice '' its been so fun play in the playpen with plushies, baby has loved her time and now it's time for her to take a nap '' she said as Alessia struggles at first but nods sleepily and continued to suck on the pacifier, closing her eyes for a minute, nanny puts Alesia in the crip, covers her up, gives plushie, kisses forhead and says '' sweet dreams, baby '' and left back to other babies to put them down for a nap too, Alessia soon fell asleep sucking the pacifier like a baby and snuggling the soft stuffed animal close to her, on the outside of the dream book, Queen Lucy was in her dimension office watching her people and Alessia too, as she smiles seeing Alessia mess her diaper outside of the dream as she continiued to looked after her people, back in nursery dream, nannies took babies in their naps after playing enough, while head nanny waited for Alessia to wake up from her nap but knows that she was messing and wetting her diapers in her sleep, after taking babies in their crips for nap, nannies went in dining hall to have a break, as the book that took her in this dream land has perfect control of the time when it brings Alessia back to real world... its not time for bringing her back yet, after couple hours, nannies took babies out of crips, changed diapers and took them back to play while nannies looked after them, Alessia was still asleep sucking on the pacifier with the fully soaked and messy diapers on as it was holding very nice,'' soon enough her messy diaper will take its hold on her and she will start to cry to get in fresh diapers " the head nanny said in her mind as Alessia started to feel uncomfortable as she started to cry like a big baby but had two reasons 1. A full and soaked diapers touching her butt and private parts and 2. A nasty nightmare of her past, head nanny felt it, came in your nursery room, walked over crip, picks you up, cradles and starts to rock '' aww, you poor baby, why are you crying? did you see a nightmare? nightmare is only a dream it nothing to be scared about... '' then nanny felt a messy diaper from between the diaper and your bottom, says '' and you messed your diaper, aww, you poor baby '' she said cooing at Alessia picking her up and carried her to the changing table and changes her 3 diapers into fresh 3 diapers, after it, nanny took the blue frilly and fluffy dress aside to get it washed, nanny brought pink onesie with long sleeves, nanny helped Alessia get dressed in it and snaps buttons on it over the 3 diapers, now your legs feel more spread wide, nanny asks '' dose baby want to go back to pway? '' she said talking to Alessia in baby talk and voice, which Alessia didn't like but nods her head wanting to go back to her plan of escape without the head nanny knowing and also to keep her mind off of the bad dream, but the head nanny already knew, as head nanny carried Alessia back in the open playpen, puts her on floor, brings babied toybox which is filled with adult-sized baby-like toys, nanny went over fridge and brought second large adult-sized baby bottle filled with milk over to her, nanny says '' nanny is needed elsewhere, dwink this once you get thirsty, baby... have fun '' nanny closed playpen, waved and left, leaving Alessia alone which Alessia crawls over to the her plan but found it gone as she didn't know that the head nany took it while she wasn't looking so she went back to coloring her next plan but found the coloring crayons and paper were gone so she went to the toybox and start to use them for her plan instead, nanny felt it and returned in work, nannies begun to feed them with baby food from jars, Alessia continued to what she was doing but soon nanny uses magic in one of the toys, once Alessia was "playing" with it, she forgets the plan she was making to escape and think like an actual baby girl, which once Alessia picked up the toy she was using as herself as the plan her mind became fuzzy and she hugs the stuffed bear giggling, nanny smiles knowing that Alessia is now happy girl playing and continues her work with other nannies, after another hour Alessia got hungry and she did the same with the other bottle of milk as she drinks it taking her time, nanny knew she was drinking the bottle with both her hands and feet, nanny finished feeding babies with baby food and placed babies back to play and started to look after their playing, after almost half an hour Alessia finished the large bottle of milk, she pants and burps and blushes and went back to her plan but her mind went fuzzy when picking up the stuffed bear again, nanny knows that Alessia finished the bottle, knowing that soon she'll pee in her diapers and poops too... nanny continues to look after babies playing with other nannies, Alessia soon started to poop and pee into her diaper with her mind still fuzzy and her body acting like a baby playing with the stuffed bear, nanny knows it and continues with other nannies, its little busy day, some of the nannies away on vacation to have some time to themselves, Alessia continued to mess and wet her diapers all 3 up but soon stopped after an hour and a half, nanny knows that if diaper is too full of mess, they would try to get in crawling position, but every time they have tried, they have fallen back on their diapered bottoms, Alessia got down on all four and started to crawl around with the full and soaked diapers, but in order to crawl with messy diapers, diapers must be in position that nothing will leak, and thats close to impossible... nanny continues her work with other nannies, Alessia didn't like the full diaper as she whimpers in her baby mind, as she gently gets up and sits didn't feeling the cold mush touching her tush and private parts, as head nanny used magic to put babies in care to sleep, comes in Alesia's nursery room, walks over playpen, opens it, walks over to our hero, kneels down, brings one hand under her chin, lifts her chin up, dries her tear with her tail and asks '' why is baby Ally crying? tell nanny '' as Alessia still hugging the stuffed bear, "diape full nana" she said with the pacifier still in her mouth making it hard for her to speak her perfect English, nanny picks Alessia up, cradles, carries over baby changing table and changed her diapers in 3 fresh diapers... nanny asks '' is baby Ally hungry?
