Author's Note

This seems like another one of my usual "involve the other ponies suddenly" chapters, but superfun requested it as s/he said s/he would request a sequel. Again, OoC stuff, but don't take too seriously.

Wow... I'm actually getting tired of writing these. Even with the new hypnosis element.

And it goes without saying - RariDash!

Hypnotizing More Ponies

Rainbow Dash came by Carousel Boutique again. Rarity saw she did not have her hypnosis bracelet this time.

"Hey Rares, can you make me a sports outfit like the one you were wearing when you were playing around in the mud?"

"Oh, the one you hypnotized me into wearing before satisfying your f-" Rarity put her hooves on her mouth.

"Yeah, I think an outfit like that would be great for playing soccer in the rain." Rainbow Dash did a double take. "Wait... WHAT?!"

"Nothing," said Rarity nervously.

Rainbow Dash was sweating profusely. Rarity knew what she did to her? She was going to get it now!

Rarity could see how nervous Rainbow Dash was. She put a hoof gently around her. "It's all right Rainbow Dash. I'm not mad at you. You'd probably never guess the kind of unladylike fantasies I've had about you sometimes, so I actually like the fact that you'd think of me first for something like that." She blushed, but went on. "And, although I wouldn't remember it... I've been looking forward to our next session."

Rainbow Dash also blushed lightly. "Are you serious?"

Rarity nodded. "Maybe the time after next time... or the time after that, I should hypnotize you. And tell you what I made you do afterwards, for what you couldn't figure out."

"Sure!"

"And... I was wondering if, for our next session, we could convince some of the other ponies to join, so I can be beside you at the beginning?"

A mischievous smirk came across Rainbow's face. "Sounds like fun! Let's get ready for it!"

...

"I've never been hypnotized before. It would be a great scientific experience!" said Twilight Sparkle.

"Sounds like fun!" said Pinkie Pie.

"Sure, why not?" said Applejack.

"I... I have to feed my pets, so maybe not today," said Fluttershy. Rainbow Dash and Rarity didn't go any further than that, for it was clear she didn't want to.

So, the ponies met up in a mud field near Sweet Apple Acres. Applejack made sure there would be no ponies coming by.

"Stare at this without moving your head," said Rainbow Dash as she waved her arm with the bracelet back and forth. Twilight, Pinkie Pie, and Applejack stared, then fell asleep. "When I clap my hooves three times, you will do whatever Rarity or I say!" Rainbow clapped her hooves three times, and the three ponies entered their trance.

"Put these on," said Rarity, throwing sports outfits to Twilight, Pinkie, and Applejack, each resembling a T-shirt and skintight shorts. Twilight's shirt was dark blue and her shorts were red; Pinkie's shirt was teal and her shorts were dark blue; and Applejack's shirt was red and her shorts were dark green.

Rainbow Dash and Rarity were wearing their same outfits from before.

"Drink these!" said Rainbow Dash, giving them each five mugs of cider, each spiked with large amounts of fart powder. Rarity had seen Rainbow Dash put them in when they were setting things up, and now knew parts of what Rainbow had made her do.

"When you have to pee, say so, and hold it until I say. Now Applejack, slap my butt as hard as I can until I tell you to stop!"

Rarity watched as Applejack spanked Rainbow Dash. This was very arousing for her.

"Twilight, I want you to swat Pinkie Pie's rear until I say so."

Pinkie turned around so her butt was facing Twilight, and Twilight began spanking her hard. Pinkie squealed each time, and Rarity loved the sight of it.

"That's enough," said Rarity after the twentieth swat. It went on for longer than she'd intended. She hoped Pinkie's butt wouldn't hurt too much when she was herself again. "Now, Twilight... sit on her head."

Twilight sat on Pinkie's head, the way Rarity - though she did not remember it - had done to Rainbow Dash.

"Ow! I think that's good, you can stop!" said Rainbow Dash, and Applejack stopped spanking her.

"Pinkie Pie, as soon as you feel the urge to fart, fart in my face!" said Rainbow Dash. She then realized that Pinkie's head was under Twilight's butt, so she couldn't do much.

"Twilight, stand up," said Rarity. Twilight did so. "Pinkie Pie, massage Twilight's rear until it's time to do what Rainbow Dash said."

Pinkie started rubbing Twilight's tush, while Rainbow Dash told Applejack to lay down and then sat on her head for about a minute.

"Oooh, this is fun!" said Rarity. "I have the perfect thing in mind next!"

Then Twilight accidentally farted in Pinkie's face. Pinkie ran over to Rainbow Dash, turned around so her behind was facing her, and raised it in the air.

PPPPPPPPPFFFFFFFFFT!

Pinkie giggled, and Rainbow Dash once again loved it.

"Hmmmm... Twilight, could you... break wind... in my face?" said Rarity.

Twilight positioned her rear in front of Rarity's face.

BBBBBBBBBRRRRRRRRRRT!

Rarity coughed on the stench, but a part of her found it arousing. She could see why Rainbow Dash had made her do this to her.

"Applejack, can you swat my rear fifteen times?" said Rarity.

Applejack walked over to Rarity and started slapping her butt over and over again. Rarity loved the feeling. And Rainbow Dash loved the sight of it, turning away from Pinkie's gassy butt.

"Now, Twilight, stand still," said Rarity, and she tied Twilight's front hooves together behind her back. Twilight farted twice while Rarity was tying her back hooves together.

"So, bondage is one of your fetishes?" said Rainbow Dash after Pinkie farted in her face again.

"When I hypnotize you, you'll find out just how far my bondage fantasies go!" said Rarity. "By the way, why hasn't Applejack broken wind yet?"

"Because, I didn't put fart powder in her cider. I don't fantasize about her that much. I'm too used to it cause she and I have had farting contests."

"What about Pinkie Pie?" Pinkie thought farts were funny, so surely she'd fart when she was alone with Rainbow Dash.

"I'd always feel more aroused by her farting, because unlike Applejack, I didn't hear her fart until after I got my fetish."

As if on cue, Pinkie farted again, giggling as she would when she wasn't in a trance.

"Now Pinkie Pie, go fart on Twilight!" said Rainbow Dash.

Pinkie ran over to Twilight and released a series of loud, long, high-pitched farts in her face.

Rainbow told Applejack to lay still and tied her up.

"Pinkie Pie, stand still," said Rarity.

Pinkie froze, and Rarity tied all four of her hooves together. Then she set her so that her butt was resting directly against Twilight's butt.

"I see what you did there!" said Rainbow Dash.

Twilight farted, and Pinkie farted in response. Though, it was hard to tell who was farting, but Rainbow Dash and Rarity could distinguish from Pinkie's farts being more high-pitched, and Twilight's farts being wetter when they weren't more deep-pitched, as well as slight motions they were making.

After nearly an hour of farting...

"I have to go pee!" said Pinkie Pie.

"So do I," said Twilight.

"Me three," said Applejack.

"Applejack, pee right now," said Rainbow Dash.

Applejack wet herself, and Rainbow Dash watched with arousal as her shorts grew wet and a puddle grew under her.

"Twilight, hold it as long as you can. Pinkie Pie, start peeing as soon as you feel Twilight peeing on you. Unless you can't hold it as long as her."

Rainbow and Rarity watched as Twilight and Pinkie Pie fidgeted where they lay, occasionally farting.

After half an hour, Rainbow Dash decided she'd had enough fun watching them squirm. She tickled Twilight's hooves with one of her feathers. Twilight laughed very hard, and in seconds she was peeing herself.

As a puddle grew under her, it reached Pinkie Pie, getting the side of her outfit wet. Pinkie Pie giggled and also peed herself. Both mares sighed of relief. Then Pinkie farted again, and Twilight farted back. They seemed like they were really enjoying this, even though it was only the trance they were in.

"Wow. This is... wow." Rarity couldn't take her eyes off it. Of course, it still paled in comparison to the fantasies she'd enact on Rainbow Dash when it was her turn to hypnotize...

"Now, next time you have to pee, hold it as long as you can, or until I say so."

Rarity decided she'd had enough fun on this side.

"Rainbow Dash, can you hypnotize me now?" said Rarity. "Do whatever else you want with me, but tie me up at some point."

"You got it," said Rainbow.

Once Rarity was in a trance, Rainbow had her drink the cider with fart powder in it. She had Rarity slap her butt several times, though it was still sore, and then massage it until it was time to fart. Rainbow Dash accidentally farted in Rarity's fate, and chuckled.

Eventually, Rarity stopped, sat on Rainbow Dash's face, and began farting on her, as loud and wet as before.

After about half an hour of farting, Rainbow tapped Rarity three times, and she stood up. Rainbow tied Rarity's back hooves together and her front hooves in front of her, then positioned her so her rear end was in the air. Rainbow stood next to Rarity's tush, and she let out a loud, wet fart in her face. Rainbow rubbed Rarity's butt, and she farted again, and again, and again. Rainbow breathed slowly with satisfaction.

"Dashie, I gotta go pee!" said Twilight.

"Me too!" said Pinkie. "I REALLY gotta go!"

Rainbow paid them little notice, too distracted by Rarity farting in her face while tied up.

Applejack was already peeing again. Rainbow quickly untied her and told her to rub her butt until she told her to stop. As Applejack did so, Rainbow Dash stood next to Rarity's butt, occasionally touching, rubbing, or slapping it slightly as she continued to fart.

"When you have to pee, hold it until I say," said Rainbow Dash.

She suddenly remembered Twilight and Pinkie. She ran over to them. Pinkie was already wetting herself again, but Twilight was still fidgeting hard.

Rainbow untied Twilight and had her give her a golden shower. Rainbow peed herself in the middle of it, and was soaking wet by the end of it.

After Rarity wet herself at the end of an hour-long hold, Rainbow decided she'd had enough fun for the day, so she untied them, had them all play in the mud with her, then set up a raincloud so that it rained on all of them, washing all the mud off them and greatly decreasing the smell of pee and farts.

Then, Rainbow clapped her hooves together, and the other four ponies woke up.

"Thank you for not leaving me in the mud this time," said Rarity.

"What in Equestria did you make us do?" said Twilight.

"Just a big swimming race," said Rainbow Dash. "I won, of course."

"Among many other things there's no need to mention," said Rarity.

"And I don't remember any of it," said Twilight. "Wow, this was quite an experience!"

"I wish I could've remembered it!" said Pinkie Pie. She winked at Rainbow Dash, who suspected she had a hunch as to what she and Rarity had made her do, but she said nothing.

"Somethin' seems off," said Applejack. "But, it's probably nothin'."

Twilight and Pinkie returned to their homes, while Applejack ran into Sweet Apple Acres, and Rainbow Dash and Rarity walked toward Carousel Boutique.

"Any big plans for tomorrow?" said Rainbow Dash.

"Not particularly," said Rarity.

"Then, how about you hypnotize me and enact your darkest fantasies! If you forget how it works, I'll bring the instruction manual."

"Oooh, sounds like fun!"

When they reached Carousel Boutique, they took a bubblebath together. At one point, Rainbow Dash hypnotized Rarity to fart in the tub, and then snapped her out of the trance. Rarity suspected what Rainbow had made her do, but only giggled and leaned her head against her.
