Rainbow Dash was desperate, frantically searching Ponyville for her friend Pinkie Pie… There was an embarrassing rumor spread around town about Pinkie’s hygiene, and she blamed Rainbow Dash despite her pleas otherwise…
 
Rainbow Dash eventually found her, who was pigging out on sweets in Sugarcube Corner by herself… Dash opened her mouth to speak, but was stopped by the terrible odor lingering through the room. It reeked of ripe farts, and the potency was like a punch in the face…
 
“Eww, Pinkie Pie-” Dash began,
 
“Leave me alone, Dashie! You’ve done enough already… Element of Loyalty.” Pinkie scoffed, leaning to her side to rip more ass. “I guess the rumor’s for the best, it IS true…” She said with a sigh, “I can’t help it, I like the smell of my farts. I just wanted to do so in secret…
 
Rainbow Dash frowned, walking towards her friend. “Look, I’m sorry the rumor got out and spread over town, but it wasn’t me who told everyone!! Somepony could’ve been listening in or something. Look, I’ll make it up to you either way if you want. Just please don’t loose your head again being depressed…”
 
Pinkie smiled a little bit, smirking devillishly “Well,” she began, coaxing an idea, “Maybe there is something you could do…”
 
“Fine, anything Pinkie.”
 
“Do you Pinkie Promise?”
 
Rainbow Dash paused to think, and then nodded.
 
Pinkie’s face lite up in excitement, not quite her normal self yet though… “Come here, Dashie! I have a surprise for you.”
 
Rainbow Dash came as Pinkie asked. Suddenly -
 
PFFFFRRRRRRRUURRRHRHRRRTT!
 
Pinkie turned on her side and ripped one right at her face.
 
“Ain’t I a stinker, Dashie?” Pinkie giggled. “I hope it’s not too much to ask, but I’d really love it if I had somepony to smell my scent with me… Kinda like it when people notice.” She blushed.
 
Rainbow Dash coughed, waving her hand in front of her nose. “Peeyew! Sweet Celestia, that stinks!!”
 
Pinkie shaked her plot playfully, then released another;
 
PBBBBFFFFHRRRRRERRRRRHHHHRRRRT!
 
The smell was unbearable, Dash wanted to run or something… But her hooves were tied, she did have a Pinkie Promise to honor. She gently tried to bare a whiff, but the smell was too much. She resisted the best she could until she absolutely had to, forcibly tolerating Pinkie Pie’s stinky rear the more she needed to breathe.
 
“Enjoying the stink?” Pinkie giggled in a playfully innocent tone. “Thanks so much for this, Dashie. Can’t wait to do this again sometime!” Pinkie leaned close to take a whiff of the toxic stench Dash was bathed in and scrunched her nose. “Might wanna take a shower or something first though,” she laughed innocently. “You really stink, Dashie!”
