"Baby Brother: A Summer of Humiliation in Gravity Falls"

Prompt: Gravity Falls: Dipper had promised Mabel that he would help her out at one of her photoshoots. Dipper had lost a bet too Mabbel. "Hey, Mabel. I'm here. So...err...whatcha want me... to do......... exactly?" He had watched and blushed as she had produced some rather oversized baby toys and clothing, followed by a massive diaper. "Hey, Dipper. Here put these on." She thrust the ensemble into the stunned Dippers arms. He stood there statuesque. "errr.... Mabel...whats...." He was cut off as Mabel took the stuff back from hi. "yeah sorry Dipper. I should do this properly really. Let me explain, I'm getting into baby photography, theres a lot of money to be made in that, but babies are generally a pain to work with and usually uncooperative and fussy...so what better way to train than on someone uncooperative and fussy. Now do you want to put this stuff on, or do I have to dress you myself? Actually I suppose that would be more authentic, putting a squirming child into a cutesy outfit, i've heard it's not exactly the easiest task" She grinned and before Dipper could react, tackled him to the floor. Dipper kicked and struggled and yelped as she stripped him down, powdered him, diapered him pulling the super thick disposable up between his legs and fastening the side straps, she pulled the outfit on over him, securing his feet and hands in thick booties and mittens rendering him fingers near useless, all whilst she tried to kick and bite and swore. He lay there on the floor mortified he had been so easily manhandled into such a frilly outfit and the diaper...he had no idea what brand this was but it felt like it engulfed him. He flushed crimson as he involuntarily cried at the feel of such thick padding and having been so easily overpoowered. Mabel chuckled. "I knew I had the right widdle mamas boy for the job." Dipper head shot up and she shook his head hard. "nono...this is NOT what i signed up for." He tried to pull the mittens off but they were securely tied, he tried to get up but the thick padding and pillowy booties made standing quite impossible. he flopped back onto his padded butt stunned. *click* "There, thats the first picture taken, and if you dont want this pic to make the rounds on social media I suggest you start playing the game little baby waby." Dippers eyes were wide with disbelief, she wouldnt carry out such a threat would she? They were siblings after all. Mabel continued to talk ignoring the look of fear on her brothers face. "now dipper, im gonna pretend I cant understand you anymore okay, and treat you like you were just a little itty bitty crybaby until the shoot is done, i've got six or seven outfits I want to try and some scenes I want to set, and you can be as fussy as you want and i'll even change the widdle babys diaper should he make a tinkle or stinky, okay but by the end of the evening i'll have a full portfolio of adorable brother pictures whether thats okay with you or not. Now lets get started shall we." "Seriously Mabel, this isn't funny you can.." "whose a widdle cutie, is that yoo? is it? is it? wassawassawoo. What are you trying to say sweetie? Do you want your baba? is that it? Is the baby hungry...maybe you want your paci, you can't need changing already cause i've just put you in a fresh diaper two seconds ago" Dipper was lost for words, too embarrassed by the sickeningly sweet babytalk he fell silent as Mabel handed him a huge baby bottle full of milk and popped a pacifier into his slack mouth. "Aren't you just the most adorable little thing. Can you give mommy Mabel a biiiig smie for the camera like a precious cutesie patootsie? Noo?" Mabel gave an over the top pout. "is someone a grumpy little baby waby, coochie coooh? Maybe this will help." She dug around in a box labelled babytoys and came out with a squeaky duck. She squeaked it, Dipper looked up at where the noise had come from, blushing at being treated like such a helpless infant. *click* "Thats going to be a cute picture isnt it, baby, Now lets see if I can make the widdle cutsie schnookum smile" Dipper was furious he tried to stand up and attack Mabel but he ended up falling over Mabels knee. Mabel then had a dangerous look in her eyes saying:" Awwww, is widdle dipper pooh throwing a tantrum, widdle babys who is naughty, gets pow pow on their bum bum". She then starts to spank dipper while he is kicking and screaming:" Sorry Mabel". Say sorry mommy mabel" Mabel snickers. Dipper gives up and screams "Sorry mama Mabel"!!. Mabel then gives Dipper the diaper back on his bum and gives him a pacifier. Then she goes back to takes pictures of dipper in his babyoutfit. She then tells dipper to drink from his baba. Diper reluctantly drink the baba while saying gogo gagaga becuse he dosen't want another spanking. While he is drinking the baby bottle and Mabel take pictures, the door opens and in enters Wendy with a smoke in her hand. She stops mid track, looks at Mabel and dipper confused then she starts laughing saying:" HA HA, what is going on?Dude why are you looking like a baby and drinking from a bottle? is that a diaper, are you wearing bonnet, and mitten and is that baby booties and is that a pacifer". Dipper tries to explain but Mabel quickly picks you up and put him on her knee while saying:" Dipper wanted to be a baby again and wanted me to be his big sister, isn't that right cutesie patootie". She then started to bounce you while piching his cheek Dipper is red with humiliation. Wendy still can't believe it saying:" Dipper dude, that is so lame, i thought you were a cool kid, but looks like mabel is the cool one, awww are you crying, do you need a diaper change or a nappy nap, cooochie coooh, can you say gugu gaga haha". Wendy then gives him a big wet patronizing kiss on his cheeks with red lipstick. Wendy then says:" Dipper pooh, i actually had thought about us being a couple, but i can't date a mamas boy, who is still just a crybaby, you do look precious, i can't wait to tell the other guys, Robbie would love to hear this, maybe we could take you out in a pram and show you off too everybody". Dipper spits out his pacifer saying:" Please Wendy, i'm not a baby, Mabel is lying, i am mature enough to date you, mabel is the only one here who is a cr-" Mabel then interups you by slapping the pacifer back in his mouth saying: "Naughty baby, we can't understand you, did you say guugu gagga, oh i know, you want to go out in your pram with me and Wendy". Dipper lookss scared but then Wendy and mabel straps him in the pram and slaps a baba in his mouth. They the drives you out in gravity falls to shows you off too everyone while they coos at you. Wendy saying:"Awwww widdle dippy is drinking his baba, here comes the choo choo train, haha". Mabel laughs and Yelling:" Everybody come see the new widdle baby of gravity fall!!!!". People in gravity falls laugh and coos at dipper. When gideon sees him, he can't stop laugh and shakes a rattle while patronizing call you babynames. When Robbie comes over he also laughs and even picks dipper up saying:" Wow, i thought i had to be worried about you stealling Wndy from me, but the only thing a widdle crybaby like you can steal is diaper change and baba feeding, haha, coochie coooh". He then bounce you on his knee while pinching your cheeks, you try to fight him but Robbie is too strong. Robbie then gives you a wet condescending wet kiss on the cheek and thanks Mabel for putting you in your place. He then straps you back in the pram. Dipper is red with anger and embarressement. He can see Wendy looks lovingly at Robbie and hear her say: "Wow Robbie i din't know you have such father skills, i think dipper poooh sometimes gonna need a man to diciplin him, so maybe sometimes we could babysit the big mamas baby"? Robbie and Mabel agrees. Then suddenly Pacifica appear and she is also laughing at dipper saying: "Wow dipper is that you? Haha, you look so babyish, i thought you were a cool dude, but looks like you are just Mabels baby brother, maybe me and mabel could play dress up with you". Pacifica then shakes a rattle in front of your pram patronizing and coos at you. She then says:" Awww that frilly bonnet makes you look like a sissy baby, awww are you a precious princces pooopie pants, haha, can you say gugu gaga, maybe mama". Dipper have had enough he tries to tell them to shut up but it just sound like gogo gaga, mama, baba, with the pacifer in his mouth and everybody saying: " Awwww, did he say mama, did he say papa, what a precious angel, maybe he wants his baba or his papa Robbie". Dipper was now the new baby of gravity falls. It was gonna be a long summer.
