You find yourself in what appears to be someone’s secret lair, except all the puzzles appear to be made for second graders. Polly is upset you’re fixing things so easy, so she evens the playing field, reducing your intelligence to that of a second grader. Problems that were simple are now much more difficult, and she says she’ll use the mind melting machine again if you’re not careful.

	Apparently even evil scientists need babysitters. You hadn’t expected that to be the case, the job paid so extremely well you showed up just to see if it was a scam or not. The father had introduced you to his daughter, Polly Sparks, and explained the details. He was going to be gone for the weekend, evil science convention he said, and you were to look after her and make sure she didn’t get into trouble. Sounded easy enough. 

	Her father had been out the door not a few second before she jabbed something into you and you fell to the floor unconscious. When you woke up things had… changed. Somehow you were unaffected, but still aware, that Polly was now the center of the universe. You know that can’t be true and wasn’t before, but you also know that it is. Strange. A plucky robot comes up to you. “Hi, my name is Botly, and boy are we in trouble.” he says.

	He explains that Polly has taken over the mountain manor and that we would have to take control back before she majorly messes up history. 

	A monitor descends from the ceiling. The image of Polly appears and she reclines in a big chair at presumably the command center. “Good luck trying to stop me. You’ll never get past all my devious clues and puzzles. I doubt you’ll even be able to get out of that cell.” Her voice was pompous, arrogant, and bratty. She seriously needed an attitude correction. But you supposed that’s what happens when your father was a mad scientist and you lived in an evil lair.

	Botly turns to you and says. “Mad scientist 101. Always give your captors a chance. That’s what makes it fun, at least that’s what Professor Spark always says.” You turn to the cell door. Botly explains this puzzle. “Its a memory game, just copy the pattern as it comes up.” You roll your eyes and sighed. It’s an easy puzzle, but it was designed by a third grader. You suppose that you probably could spend the whole weekend entertaining Polly like this. Especially for the money you’re getting.

	The patterns blink. First three blinks to remember, then five, then seven. Polly’s monitor descends again when you solve it. “What!” She shrieks. “Even I have trouble remembering seven. Well no worries, you’ll never get past the next puzzle.” The monitor retracts again. You chuckle. Botly leads you along, giving you the tools you’ll need to navigate the mountain manor.

	“This way!” Botly says. “There’s a clue over here! And another one of Polly’s puzzles.” He leads you into the kitchen where he explains you have to do some basic math to unlock the door. Once again you roll your eyes. The equations are very easy. 50 + 40 = 90, 33 + 5 = 38, and 13 x 40 = 520. 

	Polly’s monitor meets you in the kitchen. She seems upset. “I thought for SURE that last one would mess you up! How!”

	You shrug, the multiplication was a bit harder than the addition but you just kinda did it in your head. 

	“I see, it’s cause you’re an adult! You must be as smart as dad. Well we can fix that...” She disappears from the monitor for a second and you hear the clack of keys being pressed. Botly starts glitching out behind you and one of his arms transforms into some sort of beam emitter. Before you know it you’re blasted, and knock you on your butt. Stars fill your vision and you lay on the floor dazed. You feel… different. Your mind feels slower. 

	“What… happened...” You manage to say. 

	Polly returns to her monitor and gives a haughty laugh. “You were too good at this, so I evened the playing field a bit. Ohohohoho~ Botly there has a handy tool my dad calls the mind-melter! It’s meant for defense of the manor, but I reprogrammed him!” She took pride in this. “Now you should have the approximate intelligence of a second grader, one grade below mine.” Her tone had shifted into deviousness. “Lets see how ‘easy’ you find my puzzles now~” 

	You got the i-impr- *zzt!* idea that she enjoyed t-torm-*zap!* messing with you. Botly returns to his normal functions. “Sorry about that, but it’s ok I’m sure we’ll still be able to do this!” He sounded plucky and confident and that gave you in your dazed state some confidence of your own. “Ok so we have to feed mort the robot for this one.” Botly tries to explain to you the details of feeding the robot. There’s two conveyor belts, one in front, one behind, and there’s ingredients and mort will ask for an amount and you don’t remember which conveyor did what but the belt starts and away you go.

	Things moved slowly thankfully. Some of it was easy enough, three cups of chopped liver, four cups of spark plugs, and one cup of strawberries. You can still count to four thankfully, but then the 211,000 molecules of carbon came. You’d seen numbers that big before, you can clearly remember being able to comprehend it, but it dazzled you now as little zaps. And what was a molecule again? Polly giggled from behind her monitor as she watched you struggle. “Better hurry up~ That robot looks very hungry~” You look over, the robots mouth gleamed with intimidating sharp ‘teeth’ that made you suppress the urge to cry in fear.

	You grab the suction grabby thingy labeled molecular, but you’re having trouble wrapping your head around such large numbers. You accidentally manage to get the right amount however by guessing and luck. Polly huffs behind you. “Maybe I didn’t get the settings right, that last one should have had you stumped!” You tried to explain your luck in the matter, but it was too late. She was already clacking away and Botly whirred and zapped you again. “There! That should put you at a first grade level!”	Polly exclaims.

	Sparks and stars whir in your vision. Idea’s and concepts wink out in your mind. You had a slight grasp on the idea of multipl-*zrrt!* er… the x thingy in maths, guess that’s gone. You stagger a bit, legs shaking. A sudden wetness in your pants alerts you to the fact that you’ve lost control of your bladder. Slowly you slide down to your knees, sniffling in the growing puddle beneath you. Something breaks inside your mind and you start to bawl. Everything around you has become so scary, big machines and puzzles you can’t understand surround you. You’ve forgotten how you got here, what you were supposed to do.

	Polly wastes no time antagonizing your new state of affairs. “Aww, guess that last zap was a bit stronger than I thought it would be. Forget first grade, maybe pre-school is more your style.” She presses some buttons on her control station and Botly picks you up and whisks you away from the puzzles, bringing you to what looks like a nursery room. Its walls are pink and toys and stuffed animals littered the floor. Botly carries you to a changing table where your soggy pants sop wetly against the plastic cushion.

	Botly begins to take off your pants, apparently not programmed to do it normally he just cuts through the fabric, tossing the wet garments aside. For good measure he does the same to your shirt. Cold scared and naked you sit in a room that is at least less scary than the previous room you were in. The door opens, and Polly herself walks through, carrying a bundle of clothes and a gun shaped device.  “First, I don’t have any clothes that fit you and I don’t have access to my dad’s clothes so.” She fires the gun at you, causing you to flinch and raise your arms, but you don’t feel a tingle in your brain like before. This time your whole body tingles. 

	The room grows bigger, you sniffle, ready to start crying again. Polly tosses her spare clothes on the changing table. “I don’t wanna let you touch any of my good clothes either, so I’m putting you in some of my old clothes I’m too big for.” She said this with pride. “Second, what’s seven times four?”

	You sniffle and shake your head, not understanding the question.

	She smiles, getting excited. “Whose the queen of england?”

	Again you don’t know.

	She leans in, smiling wider. “And who built the pyramids?”

	Scared you pull back, she’s bigger than you now. You shake your head again.

	Ecstatic Polly claps her hands. “Perfect! Now that I’m the smartest again I’m the boss! By the way the answers are 28, me, and me!” She pulls out something from underneath the top of the table. “Since I’m the boss you have to listen to me now, so I’m gonna make you wear this.” She holds a thick diaper up. “These are my night time diapers, but I haven’t needed them in weeks now. I’ve got big girl pullups.” She pulls the front of her pants down revealing pretty princess pullups with unicorns and fairies on them. You vaguely remember now that Polly is like, really important? Maybe the center of everything, you’re not sure, but her underwear is cute, and she’s smiling an awful lot. You lower your guard slightly.

	Still something makes you protest the diaper. “B-b-but, I don’t think I need a diaper...” You definitely think you don’t, but aren’t sure why. You were bigger, but now you’re small, very small. Polly can easily lift your legs and slips the diaper under, apparently not hearing your protest. “Anyway, we can’t have you peeing all over my play room. Botly is already going to have to go sterilize the lab later cause of your accident.” She tapes up the diapers and grabs the pile of clothes she brought.

	You definitely resist at the sight of them. “B-but those are girls clothes…” You were pretty sure you were a boy still at least. 

	Polly tut-tuts at that. “Well, guess you should have thought about that before peeing your big pants then huh?” She’s still much stronger than you, and manages to get the frilly pink dress over your head. Unable to protest you give up. The dress does nothing to cover the diaper you’re embarrassed about wearing, and the cute stockings and frilly headdress she puts on you further shame you.

	She remains oblivious to your shame. “You’re so lucky, I used to love wearing that outfit. But I think the lab coat suits one of my intelligence better anyway.”  She twirls, making the lab coat splay out. She seems like she’s having fun. Still you look uncomfortable, which makes her frown. “Geez you really don’t like those huh… oh!” She has an epiphany. “I know, I’ll use the history re-writer on you!” She disappeared out the door leaving you alone in the pink room full of toys and plushies.  

	 You have some time to think finally. Botly smiles at you and says, “Well uh, honestly I don’t know how you’re getting out of this one.” You have to admit the clothes she gave you were pretty cute. They had the label ‘Pretty Princess’ on your chest in frilly purple font. A title you were warming up too. And it’s not like diapers were that bad. In fact you’ve always worn them. You were always a pants wetter, no you love messing your thick diapees! A giggle escapes your mouth. You failed out of school early on that’s right. Couldn’t even pass potty training. A thin line of drool escapes the side of your mouth as you start to blow bubbles and play with the front of your diaper. It felt good. You can’t wait for… yeah your sister Powwy to come back so you can pway wiff her. You stick your fingers in your mouth, which causes more drool to come out, falling onto your back in the process.

	Powwy is da best. She is awways there to change u n pway wiff u. You love being a good… sister to her! Yeah you’re da bestest lil sister ever! Her ‘perfect pampered princess’ she always said. Tho those words are too big for you. Only Powwy can use da big words. You’re so lucky to have her!

	You giggle to yourself with your fingers in your mouth, drooling all over the plastic changing table. Your hair, which is now shoulder length, mats behind you as drool gets on it. What once was a thin body pudges up as the ‘pampered’ part in ‘perfect pretty padded pampered princess’ adds pounds of fat as your history changes to match that of Polly Sparks little sister. 

	Polly walks back in and you exclaim “Powwy!” through wet fingers. You struggle to sit up, and carefully slide off the changing table and onto your hands and knees so you can crawl to her. She cackles. “Ohohohoho~ now nobody can stop me from rewriting all of history!” You make it to her leg and tug at her lab coat. “What is it diaper dork?” She says. You look up at her with a dumb expression, hair caked to the back of your head with drool, the area around your mouth shiny with it, the top of your favorite ‘pretty princess’ dress wet. “Pway!” you say. 

	She rolls her eyes. “Ugh I don’t… I don’t…” She wants to say she doesn’t have time for that, but years of playing together with each other roll across her memory. “Oh fudge-sickles.” She huffs, stomping her foot. You giggle at her saying a funny word. “I think I accidentally made me love you for real...” She laments. Again you look up at her with your stupid dumb pretty face. “Okay fine, history altering can wait a little longer...” You clap and exclaim. “Yaaaaay! Pway pway wiff sis sis!”

	She shows you all of her favorite plushies and sets up a tea party. Botly brings real snacks and fake tea (really just apple juice) in a sippy cup for Polly and a bottle of milk for you. You giggle like an idiot and she plays along as her usual self. Inflating her ego which you reinforce. Flaunting her intelligence which impresses you endlessly. She feeds you a bunch of fatty baked goods and sweets which you happily slurp up so she can poke fun at you for how chubby you are and grope your soft thighs and tummy. 

	Time passes and your date with Polly gets interrupted by the sounds of you grunting and the crinkle of an expanding diaper. You love messing your diapers, especially in front of your sister. You’re so happy you crawl over to her and give her a big hug. Except she’s made an error in making you so chubby. You can’t really hold yourself up for long so she ends up bearing the full weight of a flabby fat baby on top of her and she crashes to the floor. “What are you doing you dumb baby!” She exclaims.

	The only thing you love more than messing your diapers is your lovely big sister Polly. “Wuv sis sis.” You say rubbing your face in her chest. You’re on top of her now, your thick diaper crotch on top of her pull ups covered crotch. It feels good to rub against her so you do, too stupid to recognize her struggles as anything but play. “Get off me you baby bimbo!” She yells as she tries and fails to wrestle out of your grip. “I gotta pee!!! If you don’t let me go I’ll, I’ll… mmnff.” The rubbing against her crotch finally gets to her. Her struggling subsides as she rubs back against you. “Sis… I...” Words fail the girl genius. She wraps her arms around you to press harder, the only thing mattering to her now being the good warm feeling in her crotch her little sister is giving her. 

	You grip her tight as you reach the height of the pleasurable feelings around the same time as her. She sighs and your eyes flutter. All that effort tired you out and you yawn snuggling your big sister, trapping her beneath you. “Hey wait don’t go to sleep I can’t move you you fatso!” She struggles briefly but that only makes you squeeze her tighter. “Wait sis I gotta go.” She pleads, but its too late, you’ve drifted off to sleep. A puddle of drool is already forming on her lab coat where your head rests. “Botly please help I don’t wanna break my good potty streak!” She directs her pleas at her helper robot.

	“Sorry Polly, you’re on your own here.” Botly says smugly. “Guess you managed to stop her after all” He says at your sleeping body before turning to leave.

	“No wait please don’t go, please please pl-” Polly cries frantically before the tell tale hiss adds to the sound of your heavy breathing. Polly sniffles and cries a little, hugging you back for comfort. The commotion does stir you briefly. “Luv u big sis...” You mutter in your sleep. Polly clears up her sniffles just long enough to squeeze you a little and reply. “I love you too little sis...”
