((Prompt: All good things must come to an end.))
Pinkie buried her nose into Fluttershy's soft curtain of mane. They only had so much time left to be together. Five minutes, less than that, less and less as each precious second ticked by. She squeezed the pegasus in her hooves as though she could hold onto those priceless moments if she only held her love tight enough.
“I love you,” she whispered in Fluttershy's ear. “I'll never forget you, no matter what happens.”
Pinkie felt a tremor run up Fluttershy's spine. She found herself enclosed in soft, warm wings. “I... I love you too, Pinkie. What...”
“It's time,” said Twilight. Her voice rang with the gravity of a grave bell.
No. No, that couldn't have been five minutes. Pinkie wrapped her hooves desperately around Fluttershy's back, shaking her head in protest.
“P-Pinkie?” Fluttershy stammered. “Pinkie, Twilight says it's time.”
“No.” said Pinkie stubbornly. “No, I don't wanna let you go. You can't make me!”
“Pinkie, we agreed,” said Twilight. “Five minutes. You have to let go of Fluttershy.” Met with another stubborn shake of Pinkie's head, Twilight sighed.
Pinkie Pie could be a strong pony when she was trying, but Twilight's magic was like a wall of steel. A wall of shimmering, purple steel that was slightly warm and sorta tickled on touch. Twilight was careful not to harm Pinkie as she peeled the mare's legs away from Fluttershy.
“It's time,” she repeated, her voice a bit strained from the spell. She shot a glance in the other direction. “Hey, that goes for you too, Rainbow and Rarity. Come on, girls, we all agreed on five minutes.”
Rarity and Rainbow Dash ceased their kissing with a disappointed sigh. Three pairs of mares stood up and switched partners.
“Okay, five minutes for real this time, girls,” Twilight said, flipping over a glass timepiece and sitting down next to Rarity.
Pinkie wrapped her hooves around Applejack and buried her muzzle into her straw-like bundle of blonde mane. “I love you, Applejack,” she said, squeezing the mare tight. “I'm never going to forget you, no matter what happens!”
Applejack sighed. “Next time, I'm votin' for the pony-pile.”
