Rainbow Dash's Bday Surprise

Rarity manipulated the stretchy fabric with expert precision, pinning folds and taking measurements as she went. She had spent the previous week at her desk scribbling designs onto sheets of paper, and she had only just started the task of actually assembling the clothing. The design was unusual for her, in that it needed to be functional as well as stylish, but she had no doubt that she was up to the task.

Despite her confidence though, it was proving more difficult than the fashionista had hoped. For one thing, being sporting wear she would need to use a lightweight and breathable fabric. It would also need to be durable and comfortable to wear while exercising and playing sports. After searching through her stock she eventually settled upon a polyester blend that she'd only ever used for trimmings, but she knew it would be the perfect material for what she had in mind.

The clothing in question was a fashionable flight suit for one of her best friends Rainbow Dash. Rainbow's birthday was one week away, and Rarity wanted to surprise the athletic pegasus with a new flight suit that would suit Rainbow's sporty personality while providing improved aerodynamic properties that would allow the pegasus to reach her full potential.

As she was taking measurements, the bell above her door chimed, and a pony walked in.

"Sorry, I'm not open today!" Rarity called out.

"Oooh.. is that for Dash?"

Rarity immediately recognised the lively voice of her friend, Pinkie Pie, and finally looked up from her work for the first time in hours. "Oh, hello Pinkie. Yes, it's her birthday present, but it's going to be a challenge to get it finished in time."

Pinkie smiled. "Well I'm sure you'll get it done, you're the best fashion designer in all of Equestria!"

Rarity knew her friend was biased, but she accepted the compliment. "What are you planning to give Dash this year?"

"Oh!" Pinkie suddenly remembered the reason for her visit. "That's what I came here to tell you! I used to bake her something special every year, but I know she doesn't like cakes, and I've tried everything else!"

"That doesn't sound like you Pinkie, you're normally bursting at the seams with creative birthday ideas!"

Pinkie laughed, "Well I ran out of baking ideas, but then I thought of something even better!"

"Better than your baking?" Rarity tucked another fold of fabric over itself and placed a pin to keep it in place.

"It'll be close for sure, but I definitely think she's gonna love it."

"So what can I do to help? I have to warn you I'm going to be very busy this week working on my own gift, but I'm happy to assist if it isn't too time-consuming."

"That's the best part, you don't need to do anything! This year I'm gonna give her you."

Rarity finally stopped fussing with the fabric and turned to face Pinkie. "Pardon?"

"I'm gonna give you to her as a birthday present!"

Rarity frowned. "Like.. as a slave?"

Pinkie laughed. "No silly, I mean as a special birthday treat. She's gonna EAT you!"

"Now, when you say 'eat'..."
