Twilight sighed and walked toward Rainbow Dash. "If it will satisfy your curiosity and let me get back to reading," she grumbled. A quiet, yet audible fart made its way out of her rump. Its lack of volume was compensated by a tremendous length. Naturally, Rainbow Dash and Spike laughed after several seconds of this, their laughter growing more uproarious with the fart's length. Twilight moaned in immense relief.
"Haha, feels awesome, doesn't it?" Rainbow giggled. Twilight didn't answer. She merely blushed and quickly adopted a facial expression that seemed as if she was wondering why she even did what she just did. "I gotta say, Twilight, I'm impressed. That wasn't quite as long as my or Pinkie's best ones," she bragged, "but for someone who hasn't trained like we have, you've got potential."
"...Trained?" Twilight panted in disbelief.
"Well yeah," Rainbow Dash answered in a tone as if Twilight had just asked if the sky was blue. "We gotta train if we wanna be the best. You can train with us if you ever wanna learn how to fart like, say, I don't know," she said, her voice starting to wander before punctuating the sentence with a proud "this!" The room started to shake from the deep, heavy rumble. Rrainbow proudly grinned as Spike burst into guffaw. Spike's laughter grew wilder when Rainbow Dash smirked and began pushing harder, making the floor shake even more violently. Eventually, Rainbow Dash started pushing softer and softer. It sounded as if the fart was dying down, but after several seconds of near-silence, she pushed her hardest yet. After this final push, her fart reached an abrupt halt.
"Way to go, Rainbow Dash, that was amazing!" Spike cheered.
Rainbow Dash did not react to this. She felt so much satisfaction that again, all she could do was sigh. "Aaaaaaaahhhhh, yes!" she moaned. "Oh my gosh, that felt sooo good!" she sighed. Once she caught her breath, she giggled. As her laughter started to die down, she broadly grinned. It was everything she could hope for in a fart: that breathtaking feeling of relief and an extremely comical sound. "C'mon, Twilight, don't you wanna learn to fart like that?" Rainbow proudly asked.
Twilight rolled her eyes, unimpressed. "Actually, I -- " Twilight began. But she was interrupted.
What interrupts her?
