A powerful roar shook the very earth as a giant amethyst and emerald dragon threatened Wonderbolt headquarters.

Rainbow Dash struggled with all her might, trapped in the claws of the gigantic beast. As she did the wonderbolts took to the sky to save their pegasister in arms. The brave stallions and mares, the best fourteen flyers in all of Equestria, formed three squadrons and attacked the rampaging monster.

The first squadron was led by Spitfire who tried to take the drake head on as she charged forward with her squad. While she wasn’t as fast as Dash she was still the second fastest pegasi on the squad. Her efforts were in vain as the beast with one flap of its wings created a might gale to blow the wonderbolts out of the skies!

As Spitfire’s group fell Soarin led the next squadron from behind to catch the dragon off guard. However just as they neared the beast it raised it’s tail directly into their path. Causing them all to crash into its armored scales.

The last team, and the only hope for Rainbow Dash now; flew high into the sky. Hoping to catch the mountain of scales and muscle by surprise by drive bombing its head. They flew up until their bodies were silhouetted by the sun and then dive bomb down as fast as possible. Their five bodies began to create cone of air around them as they all approached mach one. None of them could actually break the sound barrier like Rainbow Dash could. But five beings going near mach one was enough to take out nearly any creature.

But just as they neared their target the living volcano saw them as they descend toward him and unleashed a thick blast of black smoke. If the force wasn't enough to knock the pegasi out of the sky, the smog in their lungs did the trick. The last wonderbolt squadron fell from the sky.

The wonderbolts pulled themselves to their hooves and they looked upon the giant in front of them. The towering beast’s form blocked out the sun as he stood with a smirk that showed off his long deadly fangs and unleash a mighty laugh like that of thunder. Shaking the very earth beneath his clawed feet.

"Game, set, and match! Did you all really think you could beat a dragon in direct combat?" The beast crackled.

"Alright, alright, you won big guy, now put me down Spike." Rainbow Dash said to her giant husband who obeyed and gently placed his smol wife down with the rest of her teammates.

"You know captain I bet we could have won if you let me join the attack run." Rainbow said to Spitfire who was brushing off her uniform.

Spitfire gave the mare a stern glare. "There is no way I'm letting a pregnant mare take part in combat training. Tartarus, if it wasn't for the fact it is your husband you talked us into training with I wouldn't have even let you be the victim.” She then turned to the other pegasus. “Alright team, that..that was terrible! Easily our worst run yet!"

"What about that time he sneeze us out the air?" Soarin asked.

"That was at least the grossest. I think I still have mucus in my mane." Silver Zoom added.

"Like it was my fault that somepony flew up my nose. I mean what kind of manic even thinks its a good idea to get that close to a dragon snout?" Spike answered back in his booming voice.

Most of the wonderbolts turned to look at Thunderlane whose uniform was still moist.

"I was going for his eyes!" He said defensively.

"I still don't understand how anypony is support to beat a dragon this way? Even during that conflict between the yaks and dragons all we could do was out fly the dragons and have them fly into each other, and that was with both Princess Twilight and her apprentice using their spells as a distraction and the yaks shooting their catapult. And we still got our plots hoofed to us." Sun Chaser said.

"At least you didn't have to fight him when he did that greed thing, that was painful and embarrassing. I mean who loses to an overgrown kid?" Blaze said.

"Yeah, sorry about that one, I really didn't know how to control this whole growth thing back then." Spike said as rubbed the back of his neck.

Spitfire sighed. “Look it's been seventeen runs now and we haven't made any progress so why don't we just call it a day now and hit the showers."

"I am all for that!" Silver Zoom said.

"You hear that flying volcano! You are done embarrassing my team for today and can turn back now!" Rainbow Dash shouted at her large foal daddy.

"Um, is there something I change and get dressed behind?" Spike asked.

"You are literally the biggest thing here, what could you possibly change behind?" Wave Chill asked.

"Besides you are already naked so it isn't like you’ve got anything to hide." Super Stream added.

"I don't know about that, he could pull out those twins I keep hearing about. Not that I would complain, I would love to do me some mountain climbing." Fleetfoot said with a smile and a wink.

"Yeah, and what exactly do you plan on doing with a dick bigger this your whole damn body? Crawl into his pee hole for nap? Maybe let him rain gold or cream on us all?" Blaze asked with roll of her eyes.

"Ooo kinky, sounds like fun." Fleetfoot said with a smile.

"Was that what you meant by hitting the shower!? Because I would rather let Fleetfoot use that strap-on she calls the cunt breaker on me again then that!" Wind Walker shouted.

"Nopony’s getting pissed or creamed on!" Spitfire shouted.

"No yet you mean." Fleetfoot said with a smirk

"Just for the record dragon pee is blue so it wouldn't be a golden shower technically." Spike said which caused everypony nearby to turn and look up at him.

"I don't think the color is the issue here." Misty Fly said.

It was in this awkwardness that Spike decided he better go ahead and get back to his normal size. Spike grunted as his body slowly shrunk down to it’s normal size. It was always an odd experience to feel one’s body expand or tighten at such a rapid pace. He then ran over to where he set his clothes while trying to cover himself with his wings and quickly got dressed. "Those books Cadence give me really knew their stuff." Spike thought as he recalled how he learned to control his size shifting and how to cast spells.

"Look at that ass, how in Gaia did you score yourself a stratodon Crash?" High Winds said, never taking her eyes off of Spike.

"Envious, Ms. Dragon Fetish? Well what can I say, I'm just that awesome." Rainbow Dash said; beaming with pride.

"Well dragons love gold. So I guess that means there really is golden plot at the end of this Rainbow." Fleetfoot said as she gave a slap to Rainbow's backside. "Now the only question is what it tastes like?"

"Keep wondering you blue prev. This is one rainbow you aren't going to ride." Rainbow Dash said.

"Hey, you're the only wonderbot I haven't taken out for a spin so you can't blame me for wanting to taste the rainbow. Especially now that you're about to be a total MILF." Fleetfoot said with a smile.

"Fleetfoot this is why nopony wants to go drinking with you. They are all worried that one sip of a beer with you and they will wake up in your bed with a sore ass." Blaze said.

"Nopony complained before." laugh Fleetfoot.

"Fleetfoot, High Winds stop creeping on Crash's colt toy and get your asses to the showers. And that goes for you too purple!" Spitfire shouted.

Spike knew she was talking to him as he was the only purple creature there, and with that shower command of hers he turned to look over to his chromatic wife. She gave him a wink, letting him know they were still going to go ahead with their plan.

"Yes ma'am." He said as he and the wonderbolts headed to the showers.

Meanwhile at the Friendship Castle

"It is so good we could all get together for tea." Fluttershy said as she drank the jasmine tea Eris had brought over. As they and Fluttershy's herd sisters enjoyed their time together.

"Well this is surprisingly helping me relax after finding out all our mothers are pregnant, and there is a chance that Spike is the sire." Twilight said as she took a bite of a cucumber sandwich.

"I think you're worrying about nothing. You know how those brothel work. Our mothers were under spells to prevent them from getting knocked up in there, and even if it was Spike who did some how do it then it would be the brothel fault not our Spike." Trixie said.

"She has a point, and besides it isn't like any of our moms are complaining about this. Mine is hoping it will be a colt this time." Pinkie added.

"You know if you’re ready to forget about that, how about we do something naughty?" Eris said with a lusty smile.

"Oh my, what are planning this time?" Fluttershy said while blushing, knowing full well what Eris normally does at their tea parties

"I happen to have here a little video of my last game night with the guys,” Eris said as she poof in a video. “And they really got into each other if you know what I mean?"

"You mean you have a video of Spikey-Wikey destroying Big Mac big ass?" Rarity said a smile lit up across her face.

"Wait, what makes ya think that Big Mac was the bottom?” asked Applejack. “He could have been the top."

And as soon as she said that Rarity, Fluttershy, Twilight, Pinkie, and Trixie broke out laughing.

"Wait, have you all slept him?" Eris asked in surprise.

"Darling I met Applejack when I and Big Mac dated, in fact we were each other’s firsts." Rarity answer

"I dated him for a while when I first moved to Ponyville. He was so quiet. It was easy to be around him." Fluttershy explained.

"We never dated but we have done it a few times during heat season. Mrs. Cake has this game where we try to see how many stallions we can each get starting with the chosen studs and Big Mac is always one of them." Pinkie said

"I also had him a few times during heat." Twilight said.

"During that whole alicorn amulet incident I took him to my bed a few times." Trixie said.

"Well I know Rainbow Dash’s first time was with Spike so she couldn't have done Big Mac. But what about you two?" Eris asked looking at both Starlight and Applejack.

"No." answered Starlight.

"Do you even need to ask?" Applejack said. Clearly a little annoyed.

"So that a yes?" Eris ask

"WHAT?! NO, TARTARUS NO! I know ponies keep making those kind of jokes about us, but I ain't never done anything like that with my kin!" Applejack angrily shouted.

"Calm down Applejack. It isn't a big deal. Just remember the rule. It is only incest if you make a foal from it. Besides even if a foal comes from it we have enough chromosomes that first generation incest isn't a real problem for us as it would be for say a hominid." Eris said, which quickly reminded everypony about what time Eris was raised in and how much she missed while she was stoned in the non-Tree Hugger approved way.

"What’s a hominid?" Twilight asked, breaking the awkward silent Eris caused.

"Eris...that ain't a rule anymore. That ain't anything anymore." Applejack said.

Author's Note

Notes: I got the number of wonderbolts by counting the ponies that are still on the wonderbolt team. There were one that we know semi-retired, and another one that was name in season 1 but never seen. So sense, Thunderlane has join the team sense then and we know from Rainbow Dash joining that there is a set number of wonderbolts, and an old one has to leave the team for a new one to take their place I'm assuming he is no longer on the team.

And for those wondering if the thing Eris said is true for real world horses, it is and because of that it is common in horse breeding.
