I know next to nothing about MLP tbh. I can name about five ponies and /maybe/ tell you about their personality. So this was my blind attempt at a fic based off a pic I saw of Rainbow/Pinkie. I shipped them off the bat oddly enough.
Disclaimer! I own nothing!
Pinkie Pie trotted down the path to Applejack's stables. The slightly deranged pony hummed a happy song and wondered what fun things she and Applejack could do today.
She was just about to sing out her friend's name, to let her know that the next couple hours of her life were going to be consumed by her energetic soul, when she saw Rainbow Dash talking with Applejack. There was something about how they were standing too close to each other that Pinkie didn't like. Applejack took another step into Rainbow's space, enthusiastic about whatever they were discussing. Rainbow leaned closer and something in Pinkie (probably her patience) shattered.
Fire blazed in her eyes and her teeth ground together. She stomped her hoof, then dragged it back angrily. Why was Applejack looking at her Rainbow like that? And why was Rainbow enjoying it?
Pinkie Pie dropped into stealth mode, creeping on the edge of the woods as she slowly approached the pair.
"And Miss Rainbow, I sure am lovin' this weather. Thank you kindly."
The speedy pony grinned and flipped her mane back. "Just my job."
Pinkie charged towards them before they could get any closer to each other. Looking back, she may have overreacted a tad. Still, when the two ponies jumped apart, her Pinkie sense did a 'I told you so' dance under her skin.
Without a word, she skid to a stop in front of Rainbow Dash and looked her dead in the eyes. Then after glancing at a startled Applejack, she moved closer to drag her tongue up Rainbow's face. Mine.
Pinkie took a step back and grinned smugly for licking her favorite pony. Rainbow was frozen in shock and Applejack was sure Pinkie had lost her mind.
