Anon had been dropped into this world of pastel colored pony's for about 2 weeks, he mostly had kept to himself even when Pinkie Pie threw him on of her Welcome to Ponyville party's after stepping on the premises of the town. However there was this one mare who seemingly never let him have peace: Rainbow Dash. Almost every other day she'd pull some kind of prank on him, whether that be breaking his window via pretending to be a ghost, or going so far as to set up prank dates with mare's who never existed. Anon became more and more agitated with these pranks, and wanted to make Rainbow Dash pay for all of them. He was walking down the Everfree Forest one night to clear his head after a stressful day. As he did, he noticed a giant tree in a clearing, so he walked towards it.
"Man, either I'm stressing so hard I'm tripping balls, or this is the weirdest thing I've ever seen." Anon walked to it, and soon was there in the opening. In which he saw a weird device out in front of the tree, he walked over to retrieve it.
"Huh, this is the weirdest watch I've ever seen." he said as he put it on, he then felt the weirdest surge in his body, as if a sixth sense was welling up within him, before the rush suddenly faded off. This left him feeling pretty dissapointed, but he found the watch to be cool so decided to hold on to it. About an hour later he walked back into town, he wasn't thinking about much and was just excited to get home and crash on his super huge couch he acquired from the Apples. Then he noticed just outside of a house was a strange figure, as he got closer to it he saw it was a woman, floating with one eyeball, and weird hair. Suddenly the Watch reacted and identified her, taking Anon by surprise as it locked onto the creature, and showed it was called Insomnia.
"W-what the hell is this!?" exclaimed Anon, as then the creature froze before then tossing something to Anon before running away startled. He looked to see it was a medal with the creature on it. He was now asking what he got himself into when the watch suddenly popped out a mini booklet dubbed "Yo-Kai for Dummies." He was now more curious than surprised, so he walked home and began studying this book. Now he knew these creatures were called Yo-Kai and that many of them do different things, like Insomnia is a Yo-Kai that induces insomnia and poor sleep. Anon was enamored and fascinated by this, as he read through and learned more about all kinds of Yo-Kai. He then had a devious thought cross his mind.
"Well....i guess i can use these Yo-Kai to finally get some much-needed payback!" With that he went to sleep. He awoke the next day and started formulating his plan as to what to do with Rainbow Dash. He thought about all the time's she pranked him, and a lot of them were fake dates.
"Well if she's trying to play matchmaker, it's clear she has something suppressed if she wants to help." said Anon slyly as he wrote down the first Yo-Kai to find, he then thought about how fast she ran away after pulling off some of her other pranks.
"Also, she could use some slowing down too." he said as he wrote down 2 other Yokai who could help. With that he went into town to find these Yo-Kai, as well as gather a few things for what he had in mind. He found the first Yo-Kai he needed to carry out his plan, Cupistol, who was casually shooting at the park making some of the ponies fall in love, Anon got near to him and the Yo-Kai just stared boredly before handing him a medal. Anon ensured the Yo-Kai that he had a special job for him later, which gave him some excitement back. Next, he found a Yo-Kai by the name of Hungramps, sitting just outside of a restaurant where a very large mare was mercilessly mukbanging food inside, the Yo-Kai actually came up to him and gave him the medal. Anon was humbled by this as he then offered a cupcake in exchange, as he set off to find his last Yo-kai he needed, which just so happened to be sitting outside of a random home, Cutta-nah, when he then peeped inside the window, he saw yet another enlarged mare snoring on 3 gamer chairs in front of a computer. Anon then noticed the Yo-Kai was also snoring and decided to just seize the medal for himself. With all that out of the way he went shopping for some more of the things needed for his plan. Afterwards, he then penned and shipped a letter to Rainbow Dash as soon as he came home to have her come over the next day. When Rainbow Dash see's this letter, she's confused, but at the same time is already formulating how to prank Anon when she comes by.
"Hmm, maybe i can pull another fake date. Or maybe just pretty myself up having him think I'm into him, when really I'm gonna kick him in his crotch area, yea that's what I'll do! But not too much, no need to be a pageant queen like Rarity." she thought to herself as she got to sleep to arrive early at Anons house tomorrow. When tomorrow came, she just fashioned her hair into a ponytail which is as far as she knew, was her very serious attire. She then flew fast to Anons doorstep and knocked. Inside Anon had everything prepared for his plan, as he opened the door a heart flew past him and hit Rainbow Dash as he completed opening the door. He then noticed Rainbow Dashes expression change from sly to a weird gawk, he then noticed blushing and then, boom, her wings went up. He'd learnt that when a pegasus is feeling sensual their wings automatically went up stiff as a brick. Rainbow Dash meanwhile was in a flustered panic, rather out of character, so Anon decided to have fun and play dumb.
"Hey, you ok? It seems somethings wrong?" he said impressively feigning concern whilst Dash tried to get her wings to go back down.
"U-uhm no, no everything's fine yea fine." she said quickly "Uhm, i know i just got her, but can I use your bathroom really quick?" Anon happily obliged, as she then sped into the bathroom. Anon was chuckling to himself, as he gave a thumbs up to Cupistol as Cupistol then winked before departing. Now that Rainbow was distracted, he could set up everything else. Meanwhile, Rainbow Dash was in a state, now losing her mojo as these weird feelings suddenly came in after only seeing Anon.
"W-what's going on? I look at him like i normally do every day, and yet...why does he now make me of all ponies swoon-NO, swooning's for nerds! Clearly i flew too fast....or not fast enough-SNAP OUT OF IT!" said Rainbow as she then slapped herself in a get yourself together fashion. "Ok just calm down, you need to go back out there or else you'll look weak...if that's what he's into- NO!" she then slapped herself again, as she finished lowering her wings. Rainbow then took a deep breath before walking out of the bathroom. As she did, she noticed a bunch of scents in the air, as she saw Anon on his couch watching tv.
"Hey Rainbow, come sit with me on the couch." this sentence made her wings go up again, but she was less fussy than before for some reason, as she then trotted up to the couch and took a place next to Anon, wings still spread stiff, which Anon took notice of this, and once again played innocent to his own ends.
"I see your wings are still being odd, mind if i help you?" he asked. Rainbow found it impossible to say no, as now her feelings and mind were in a weird state around Anon.
"S-sure, i don't k-know what's up with them." she said. With that, Anon began massaging her wings to have them relax back down, all the while he saw how quietly, but deeply Rainbow was breathing, with red blushing all over her face. With this, he decided now to press things further.
"You know Rainbow, you've pranked me so many times since i got here," he started "Although i couldn't help but notice alot of them were fake dates." he said as he leaned in further and the massaging got more intense, with Rainbows breathing getting more deep and noticeable.
"I was wondering, Rainbow, if you were doing this because you had something for me?" he then leaned in to whisper in her ear.
"Hiding feelings isn't your thing, i know you've been wanting me, and I want you too." At that point Rainbow lost control and then pulled Anon in for a deep kiss, which Anon was looking for. Rainbow then quickly ended it as suddenly as it started, now unable to help but stare into his face, uncontrollably blushing.
"It's ok Rainbow, or should i be saying.....sweetie?" Rainbow then buried her face, squealing and blushing all at once. At which Anon then rubbed her back "Well, I'm assuming since you just woke up, you must be hungry?" As he said this, her tummy rumbled violently, as Hungramps had touched her leg. She quickly nodded in agreement.
"Well follow me to the Kitchen." he said, she followed quickly to then see a huge table, filled to the brim with all of the most fattening foods imaginable. At which point she'd normally eat some of it and then go to a salad shop or gym after, but right now she was so hungry and turned on she just immediately went to town. Eating burgers, fries, buttered noodles, chicken nuggets, drinking lots of soda. She went to absolute town on the food, as she did, she rapidly expanded, ber belly soon was touching the floor with how much she had eaten, and her flanks were wide and jiggly to the point of quietly clapping together as she was energetically eating the food, she soon gained a double chin, and not far behind a triple chin. Her face became chubbier as a whole, and her legs had widened to the point of touching, when she finally finished she was a now extremely fat mare, to the point she struggled to move.
"*pant*...I'm so...*pant*.. tired for some reason...*huff*...BUUUUUUUUUUUUUUUUAAAAAAAAAAAAAAARRRRRRRRRRP" she had let out a massive belch from all the gas, hitting Anon in the face with it, but he didn't mind. For some reason burps in equestria never smelt bad to him. Then Cutta-Nah came around as she then struggled trying to get up from her chairs, then tapping her now fattened butt. She then stopped trying almost immediately.
"I can't move....and i feel to comfy here...mmmmm." she said as she sat. Anon was satisfied with this response.
"Well Rainbow i can just carry you up to bed then, you've had an exhausting day." he said, even though it was still early morning, Rainbow didn't know as she was busy being fat and lazy. He picked her up, surprisingly with ease, as he carried her to a downstairs room he had specifically prepared for this. Everything screamed most comfortable in your lifetime, and he sat Rainbow Dash on to the super huge comfy mattress, to which she giggles and snickered as she felt the insane comforts this bed now provided her, incentivizing her to stay relaxed and cozy with her new bod. Anon then stood in front of her.
"Welcome to your new room, you will be staying here as long as you wish. Now, i want to get deeper with our relationship, seeing as you like things fast." he said as he then pulled out a huge swimsuit.
"You don't have to move a muscle as I will put this on you." he said, with Rainbow blushing happily as he then proceeded to fondle, maneuver and roll Dash around until the swimsuit was finally on, and it was super tight to where everything was even more accentuated with Rainbows now blubbery form. Anon then proceeded to strip.
"Dash, I'm going to plow you hard tonight, but understand you will need to address me differently, from now on...call me daddy." he affirmed.
"Yes daddy, so where do you want to start?" she said sensually. Her butt was facing Anon, and so he just leapt onto her giant butt, the thing with the swimsuit was it had a designed hole for the penis to go, and so he put his long shlong into that plump flank, with Rainbow squealing in excitement. He continued going harder and harder with every thrust.
"This butt is so jiggly, makes me want to see it clap!" Anon then proceeded to spank her huge ass hard, leading to her but clapping hard on his schlong. Rainbow panted harder and harder with every thrust, every spank, every jiggle and wobble in her body just left her in a state of ultimate lust, the two soon came to climaxing, but Anon stook charge as he grabbed her ass hard, and then came up to her ear...one word.
"Cum." and with one more thrust she squealed hard as satisfaction came pouring out of her pleasure, and not long after Anons pleasure went into Dashes. The two panted, exhausted from their passionate show of love, with Rainbow soon nodding off, as any semblance of stamina was practically nonexistent after all her changes as she started snoring heavily. Anon laughed at this as he then took off the swimsuit, and then bathed and cleaned her up. Afterwards he left her to her sleep, not before a kiss on the cheek. Hungramps and Cutta-nah followed him out.
"Great job guys, you may go do your own thing, I'll let you know when your needed again." said Anon, and the Yo-Kai gave thumbs up as they left.
"Right then, time to see how to reverse all this before she wakes up." said Anon as he skimmed to a certain section about inspiriting, he read a bit before noticing a section on triple inspiriting and it read: If 3 Yo-Kais inspirit 1 being, then the effects of said inspiriting are permanent and cannot be undone. This left Anon shocked, he had just accidentally made Rainbow Dash his fattened mare friend in a day....or was it an accident?
"You know what, screw it. This wasn't an accident, this was destiny! Now i have a home, a purpose, and a sexy partner, so thanks Yo-Kai Watch for delivering my destiny! Now to finish that movie i was watching." he said as he went back to the couch to continue watching his movie, now confident in his future with this device that let him talk to the spirts, and now he doesn't have to fear any more pranks from Rainbow, as she's too fat, lazy and in love to do anything now. Everything was now not quite the same, but for Anon, that was perfect.
