Rainbow Dash is stretching out when a familiar voice rings out, saying, “Hey dweeb!”   The limber lady gets to her feet, glancing over her shoulder with a smirk as Gilda jogs over to her. Well, jogs and jiggles, as the larger girl’s body has a great deal more heft and cushion, specifically in the area of her chest and backside. But that doesn’t intimidate Rainbow in the least; she has, after all, faced down bigger, meaner, and more stacked opponents in the past.   “Hey Gilly,” she says with a laugh. “I didn’t think I’d see you out here. I thought you hung up your racing stripes after I smoked you last time.”   “Psh, as if,” the white haired bimbo says with a roll of her eyes. “The thing you seem to be forgetting is that last time was a sprint.” Bringing a hand up to her chest, Gilda gives a condescending smirk. “I admit you beat me there, but I’m built for distance, not speed.”   Rainbow snorts and pounds a fist to her own hand dwarfing melons, causing them to quiver and shake at the impact. “Puh-leeze. I’m at least ten times the athlete you are, and today, I’m going to prove it. I bet I’m going to finish in the top five without breaking a sweat.”   A quick laugh escapes Gilda’s throat as she sizes up her friend. “Yeah right, you’re going to collapse before you even get a quarter of the way through. Better still, you’ll fall face first into a pool of your own puke. Hell, I’d pay to see that.”   “We’ll see,” the smaller girl says as a voice rings over the megaphone.   “Attention all racers; please make your way to the starting line.”   The two girls exchange looks before joining with the throng of scantily clad women crowding around banner stretched out overhead. With a little bit of jostling, Gilda makes her way to the front, Rainbow squeezing in behind her before the crowd fills in the empty space. After a few moments of standing around waiting, the voice speaks again.   “All right ladies, we’re all set for the Ponyville Marathon. Now I do want to remind you that this is a long race, not a sprint; so don’t blow too early or you’re going to end up at the back of the pack.”   A number of girls giggle at the choice of words, but the announcer continues undeterred.   “Now, you all should know the rules, so let’s not waste any more time and get right down to it. Ready? Go!” An airhorn blares and the high-heeled stampede begins in earnest; bimbos of all stripes mincing off the mark.   The herd carries on as such for a good hundred yards before girls start thinning out and going off in their own directions. Small sounds of delight echo up from some of the early girls, but Rainbow keeps going, as does Gilda. Twenty steps later, and they’re almost entirely alone as the other bimbos have already begun their ‘race’.   All around them girls are bouncing in the laps of their chosen partners, goofy smiles on some of their faces, while others already have their eyes rolled back into their heads. Gilda gives a snort as she glances around for a partner. “Psh, no stamina. What a disgrace.”   “Well, it is a free bone for some of them,” Rainbow admits, grinning as she finds her target. “Alright Gilly, I’ll see you at the finish line. Just don’t be jelly when I’m the one looking down on YOU!”   “Whatev. Hey! You! Little dork! Get over here!”   Dash laughs, hurrying up to her charge. She flashes a winning smile and winks at him. “Hey stud, did you know that the longest any girl has gone without an O in the Ponyville Marathon is thirty-six minutes? How about you and I try to break that?”   Not willing to wait for a response, the petite bimbo pounces on her chosen male and giggles, sliding aside her almost non-existent bottoms and lining herself up. Briefly, her raspberry eyes dance up to his and she smirks. “Let me know if you’re about to blow though, all right? I need to be ready not to O if you give me a monster creampie…”   Bimbo sports are weird.
