The Grand Finale

Starlight Glimmer had accidentally seen what Rainbow Dash and Rarity would do to each other on their hypnosis sessions. They hadn't seen her, and she knew she should have turned away as soon as she saw Rainbow Dash making Rarity satisfy her fetishes, but she couldn't help but stare.

Her fetishes ran just as deep as theirs, and there was one pony she really wanted to satisfy them all.

Princess Twilight Sparkle.

As soon as Twilight returned from an event at Canterlot, Starlight approached her.

"Um... Twilight?"

"Yes, Starlight?"

"I was wondering... I know a hypnosis spell, and I'd like to test it on you, to see its effects on alicorns."

Twilight raised an eyebrow.

"I promise I won't make you do anything violent or get rid of cutie marks or anything!" Starlight said quickly.

"Well... all right. I've been hypnotized once before, and Rainbow Dash used a hypnosis ring then. I've never really been hypnotized by a spell before."

Starlight cast a spell on Twilight. Her eyes swirled and she entered a trance.

First, Starlight had Twilight put on the sports outfit she had worn when Rainbow Dash had hypnotized her. Then she had her drink ten bottles of soda, each of which she had enchanted to make anyone who drank just one of them extremely gassy.

BUUUUUUUUUUURP!

Starlight giggled at Twilight doing something so unprincesslike, and knew it was about to get better!

While waiting for the fart soda to take effect, Starlight preened Twilight's wings, and then licked her horn. In the middle of this, Twilight farted loudly. As if this was a signal, Starlight stopped licking Twilight's horn.

"Now, lick my horn until I tell you to stop."

Twilight licked Starlight's horn repeatedly, farting loud and wet every once and a while.

After about four minutes, Starlight told Twilight to stop and lay on her side. Twilight did so, farting as soon as she was in position.

Starlight massaged Twilight's back hooves for about two minutes, and then licked them for another minute. Twilight laughed, as she was ticklish, but Starlight held her hooves in place.

Once Starlight was done tickling Twilight's hooves with her tongue, she had her stand still, got behind her, and started rubbing her rear. Twilight's butt was so soft, and she loved the feeling of it against her hooves. Despite her trance, Twilight seemed to like it as well.

PPPPFFFFFFT! BBBBBRRRRRAAAAP! FFFFFRRRRRRT! PPPLLLLLTH! BBBBRRRRT!

As Twilight let out more boisterous wet farts, Starlight inhaled deeply, and pressed her head against Twilight's tush. Twilight farted again, and Starlight loved it. After another loud fart that blew her mane back a bit, Starlight playfully slapped Twilight's butt, and then laid down on the ground.

"Twilight, sit on my head!"

Twilight sat down, and immediately jumped up, as her butt was poked on Starlight's horn.

"Oh, right. I forgot." She positioned her head sideways. "Try it again."

Twilight sat on Starlight's head. She loved the feeling of Twilight's rear on her face. Her shorts smelling like farts only made it more arousing for Starlight.

PPPPPPPPPFFFFFFFFFFFFRRRRRRRRRRRRRRT!

Twilight farted very loudly for 12 seconds, and Starlight let out a muffled moan of pleasure. Then Twilight let out a much shorter, but equally loud fart.

Once Starlight was satisfied (ten minutes and many farts later), she levitated Twilight off her, and told her to tie her up. Twilight tied Starlight's back hooves together and her front hooves in front of her.

"Now, spank me until I say so."

As Twilight slapped Starlight's butt with her hooves, Starlight took great pleasure in each swat, as much as it hurt.

After twenty swats, Starlight told Twilight to stop.

"Now, fart in my face some more!"

Twilight positioned her rear end in front of Starlight's face and let loose with a flurry of wet farts, each one loud and ranging from three seconds to sixteen.

Twilight continued to fart on Starlight for about an hour, until she put both her front hooves on her crotch and frantically danced around. The trance did nothing to change the fact that she needed to pee badly. The ten sodas had gone through her.

"Hover above me, not too far."

Twilight flew just above Starlight so she was directly above her, and close to her.

"Now... just pee."

Twilight's skintight red shorts darkened, and pee rained down on Starlight. Starlight moaned in extreme fetishy pleasure as Twilight kept peeing, her stream getting harder, and her shorts and back legs wetter.

Wow, she's still peeing, thought Starlight as her golden shower continued without any signs of stopping.

In just under three minutes, Twilight finished wetting herself, and Starlight was a little disappointed when her golden shower was over. Twilight let out a very loud and very wet fart for about six seconds, followed by two shorter farts that were just as loud and wet as before.

"Untie me now," said Starlight.

Twilight untied Starlight, who told her to go play in the mud. Starlight always liked to see mares getting dirty in this way as well. Once Twilight was covered in mud from head to hoof, Starlight had her take a bubblebath. Twilight farted in the tub about 20 times, and peed again. After which, Starlight told Twilight to get out of the tub, and magically cleaned her, so that she was spotlessly clean, dry, and didn't smell bad.

Starlight had Twilight undress, put her outfit back where she got it, and then magically snapped Twilight out of her trance.

"Was that it?" said Twilight. "It seems like it only took one second. Just like when Rainbow Dash hypnotized me. How long was I hypnotized for? What did you make me do?"

"A whole bunch of stuff that probably wouldn't interest you," said Starlight. "Like, playing in the mud, for instance. But as you can tell, I cleaned you up nicely."

"Sounds fun," said Twilight. "We should do this again sometime!"

"Yes, we should," said Starlight, and she was looking forward to it.
