"Rainbow Dash!" Mayor Mare announced, holding the slip of parchment with the pegasus' name written on it.
"Oh yeah! That's right!" Rainbow cheered, jumping up and down in excitement.
"Calm down Dash, they haven't even named the stallion yet." Twilight commented, trying to slow down the pegasus' enthusiasm.
"Really darling." Rarity added. "You could be matched with some gross, or older ruffian."
"Like how they matched you and Filthy Rich two years ago?" Applejack laughed. "Boy, the look on your face sugercube was just priceless."
"Yes, well..." Rarity scoffed a little. "The only reason I even took part was for tradition. And because he paid me quite handsomely later that day."
"Shh, she's about to call the stallion." Pinkie hushed her friends. "I wonder who it'll be."
"Probably some hot stud." Rainbow flaunted. "Maybe Thunderlane, or Big Mac, no wait, maybe-"
"Rumble!" Mayor Mare called, holding the slip with the pony's name.
Slowly, a light grey pegasus stallion made his way to the stage. His dark gray, slicked back mane alone with his somewhat toned appearance showed him off as a much younger pony. Just barely legal enough to take part. His white shirt hugged at his flat body, and his dark grey shorts seemed to subtly reveal a possible bulge too big for his age. Saying nothing, Rainbow also made her way to the stage. Her attire was similar to Rumble's; a white shirt with her cutie mark that hugged her petite chest, along with a pair of dark blue short shorts. Since becoming a Wonderbolt, Rainbow had developed quite the reputation among the cadets as being "tight", though no cadet would dare claim they know from experience.
"Well, it seems this year, the Heated Vote will be Rainbow Dash and Rumble." Mayor Mare called to the audience. "Now, as it is tradition, Rumble, being the younger one gets to decide what happens." She then turned her eyes on the young stallion. "Okay Rumble, what would you like to do with Rainbow Dash?"
"I want a tit fuck!" Rumble let burst out of his mouth, only to cover it in an embarrassed look. "I-if that's okay."
"Nothing wrong with that kid." Rainbow said, placing her hand on Rumble's shoulder. "But I doubt we'd be able to - hey?!" Before Rainbow could finish, her chest suddenly swelled, and then grew. It grew and grew until they were no longer the petite A cups but now a luscious and soft M cup. "What the buck?! How did this?" Rainbow then turned to her friends and saw both Twilight and Rarity giggling and dimming the magic in their horns.
"Looks like we have a tit fuck everypony!" Mayor Mare called to the cheering crowd. Rainbow simply sighed and accepted this, knowing her shirt was now destroyed from the growth spurt. "Let's get started!"
With Rainbow now leaning forward, Rumble reached towards his shorts and pulled them down, revealing a rather surprising shock. Rumble was surprisingly hung, as if a third arm grew between his legs. Due to his shy nature and how quite he always was, most normally overlooked him. So it came as quite the surprise, making even some of the younger mares he knew mouth a wow. Even Rainbow was quite impressed she never noticed how big Rumble was. The stallion himself had always considered himself small, or at least moderate. But with his now fully erect cock monster out, he aimed it's thick head towards Rainbow.
Gentle, at first, Rumble placed his long cock between Rainbow's breasts. To him, she was soft to the touch, her newly massive breasts swallowing the stallion's cock; the only thing visible was his heavy balls at the bottom and the pre cum dripping head at the top. Rainbow giggled at how quickly Rumble was already leaking, but it was expected; this was probably his first time. grabbing the sides of her breasts, Rainbow started bouncing the soft mounds up and down, letting Rumble's cock becoming closely embraced.
"Gonna cum already?" Rainbow teased, applying more pressure, making Rumble moan softly against her body. "No need to be shy, we'll have plenty of time later."
"L-later?" Rumble asked, trying to hold in his quick orgasm.
"Yeah stud." Rainbow leaned in, close enough to whisper. "I want to feel that beast in my tight pussy."
Rumble's eyes widened, yet his pupils became pin pricks at the thought. Unable to hold himself back, Rumble let out his orgasm. Despite how quick it was, the burst was a near geyser of cum. To the shock of the crowd, Rainbow's breasts were coated in cum. Loosing the strength in his legs, Rumble fell to the ground, his breath heavy, The crowd cheered at the completion, many stallions and mares were rushing to secure and even schedule orgies with each other when the heat season would come. But Rainbow looked at Rumble.
"Wow." Rainbow exclaimed, rubbing the cum on her breasts as the crowd cheered. "I didn't think you'd bust that fast." But Rainbow also saw the young stallion sniffle a little, disappointed he wasn't able to last. Leaning down, close enough to whisper again. "Aww, it's okay, really. Besides, I think we can finish this up at my place." At those words, Rumble felt the blood rush back to his cock, letting it grow to at least half mast. Rainbow smiled, grabbing Rumble's hand. "See, let's head back to my place and have some more fun big boy."

Sorry how short this was, but this is a 1K challenge. But if I can think of a better plot, I may make a longer sequel.
