I’d like that! How would you suggest I expand up on it?

@Feeder Applejack  
i need a full story of that!

It was Rainbow’s own fault, really; yes, it was Twilight who had gained weight over the past several months, but it was Rainbow’s constant teasing that drove her over the edge – and I do mean constant, having spent every moment around Twilight making cracks at her weight, telling her to exercise, prodding her flabby butt like cattle – but no more. All it took was a simple spell for Twilight to turn everything around, helping her lose weight and put it into some other target.  
And only one target felt right for her…  
“T-Twiliiiiiight,” Rainbow Dash whined in her new nasally voice. “Change me… b-b-back… pleathe?”  
Twilight – now more trim and toned than Rainbow ever was – looked at her with a devilish glint in her eyes. She chuckled beneath closed lips.  
“Now why would I ever do that?”  
“It’th not fair, though! You were never thith… f-f… f-f—”  
“Fat?” Twilight walked closer. Rainbow stepped back for fear of what she’d do next, but Twilight caught up with her far too soon. She just… didn’t feel like walking that far. Her resolve was no longer there.  
Twilight held Rainbow’s new belly flab in her hands, startling Rainbow with her firm and sudden grip which felt cold to the touch.  
“I seem to remember someone saying I needed to lose weight. And I did! All thanks to you, Rainbow Dash…”  
“B-but I—!”  
“Shhhhh!”  
Twilight raised her index finger up to her lips and leaned in. Rainbow felt she was far too close for comfort… and yet… it thrilled her, in a sense. Her cheeks started to glow red. Why was she only now noticing that hungry look in Twilight’s piercing, lavender eyes?  
“I’ll admit, I took… a bit more from you than your physique – my awkward bookishness, for example, even though I’m still just as smart. It also looks like I took some of your willpower. Just enough to keep this slim, athletic physique, and I thank you for that, I really do.”  
“I-I jutht… I wanna fly again… pleathe, T-Twilight?”  
“Mmm, say that again. Say my name.”  
“T-…Twilight?”  
“Mmnf…” Twilight closed her eyes and threw her head back. Her tongue traced the rim of her lips – slowly, passionately. Rainbow’s cheeks grew even redder.  
“You know…” Twilight raised Rainbow’s chin (her first one) to look her in the eye as she leaned in closer and closer. “…I think I’ve found something else you can be good at.”  
Gulp.

Is the outfit a nod to this? (One of the first “Nerdy Rainbow Dash/Rainbow Dork” pictures.)
 

Plenty to hold on to
