It had been two weeks since Fluttershy and Sunset Shimmer got back from their honeymoon.

Sunset finished work at the mall and went straight home.

"Fluttershy, I'm home!" said Sunset.

"In the bedroom, Sunny," said Fluttershy.

Sunset walked into the bedroom to see Fluttershy laying on the bed in the black bikini that Sunset had bought for her after she soiled her green bikini.

"You look... amazing," said Sunset, blushing at the sight before her.

Fluttershy giggled. "What do you want to do now?" She winked at her.

"I can think of one thing," said Sunset, climbing into the bed.

Suddenly, Fluttershy farted loudly. She blushed lightly but giggled, because she knew Sunset liked it.

"Do you have to go to the bathroom?" said Sunset.

"I'm not sure." PPPPFFFFFFFFT! "Yes, I do."

Fluttershy ran to the bathroom, her farts getting dirtier and wetter.

Just as she closed the door, she let out a sloppy wet fart, soiling her bikini slightly. She quickly pulled her bikini down, sat on the toilet, and let go.

PPPPPPPBBBBBBBBBBLLLLLRRTTTTTH!

Fluttershy let out a sigh of relief, along with a torrent of diarrhea that splashed into the toilet.

Sunset giggled at the sounds that could be heard from inside, as well as feeling a little aroused. Who'd have guessed a girl like Fluttershy could fart so loud?

About 15 minutes later, Fluttershy was finally done.

"You okay in there, Fluttershy?" said Sunset from the other side of the bathroom door.

"I'm all right," said Fluttershy. "I'm feeling much better. But... the toilet is overflowing, and we're out of toilet paper."

"That's all right. I'll fix it first thing next morning."

Fluttershy pulled her bikini back up and exited the bathroom to see Sunset waiting for her in her underwear, which looked very similar to Fluttershy's black bikini.

"Um... my swimsuit might be a little dirty," said Fluttershy.

"That's all right," said Sunset. "At least this time it's black so we don't have to worry about a stain." She slapped Fluttershy's butt playfully.

Fluttershy giggled and they climbed back onto the bed and had their sex.

Author's Notes:

This will basically be the same as the Twilight/Rose one.
