Rainbow Dash impatiently stamped her hoof as the line stretching through the Mall of Equestria grew and grew. “C’mon, c’mon, just open the store already! It was supposed to open ten minutes ago! I camped outside last night for this!” She called through her hooves towards the stressed-looking employees on the other side of the store shutters. The release of the new Daring Do diorama blind boxes was a huge event for the fandom, and Rainbow’s heart was beating out of her chest with anticipation, almost harder than when she was soaring through the stratosphere. She knew it’d be a stampede once those doors opened, and she’d have to grab one fast!
But then, something else drew her attention. “Oh, please, Silver Spoon! It’s not THAT heavy! I just bought, like, a half dozen new dresses and accessories! What’s the big deal?”
She turned her head, to see a familiar filly coming trotting out of the store next door. She recognized her. Big and pink. It was Diamond Tiara, that spoiled brat! And panting along behind her was Silver Spoon, with multiple shopping bags draped over her. “Can’t we… slow down a bit? I can’t… carry… all this!”
Rainbow blushed. She always hated seeing Diamond Tiara in public. Not just for her bratty attitude, but also for the… strange feelings the filly evokes within her. Her heart flutters a bit, seeing that fat figure. That big belly swaying back and forth beneath her as she walked, imagining what it must sound like. Most flustering was the sight of the filly’s big, fat butt cheeks bouncing with every single step she took, and Rainbow just wished she could shove her face into that deep, dark canyon between them.
“Hah! Can’t carry all those groceries, huh? Maybe I’ll sit on you, show you what heavy REALLY means!” Diamond threatened. Silver Spoon shuddered at the idea, but Rainbow’s cheeks flashed a deeper shade of red. Damn it, why was this making her all hot and bothered? Her heart was beating out of her chest, and she knew she’d do anything to have the filly sit on her with all that soft fat…
But then, her attention was dragged away by a siren, and the store shutters finally opened. Distracted, Rainbow rushed to join the crowd in fighting for Daring Do merchandise.

She emerged from the mall victorious… but she couldn’t get that butt out of her mind. Why did Diamond’s rump have to taunt her so? It had always been her greatest secret that she had a… well, a thing for fat fillies. But she suppressed it as well as she could. Still, it was hard not to think about fat little fillies at all times…
“Hi Rainbow Dash!” Rainbow was startled when Scootaloo emerged right next to her. “Did you get the blind box?”
Rainbow shuddered, and then composed herself. Scootaloo was the only filly she knew, but she was so scrawny, so skinny… but what if she was as fat as Diamond Tiara? Then she could have a fat filly around her at all times, just for her to enjoy. She’d spent so many hours imagining Scootaloo with a big fat swaying gut and two fat round asscheeks, and it always made her feel faint. Surely… it wouldn’t be too bad to give into temptation, right? Who could it hurt if Scootaloo got a little bigger? All she would do is look! It was a win/win situation, really…
She tried to act cool, proudly showing off her blind box on a wing. “Yep! My conquest from the field of battle! Haven’t even opened it yet!”
Scootaloo’s eyes sparkled. “Wow! We should totally see what’s inside together!”
Rainbow Dash paused, staring at Scootaloo, mentally adding a couple hundred pounds to her figure. She just had to resist the urge… she had to…
Where should Rainbow suggest they go?
