"And that is how dragons can naturally change their biological sex, but it only works for drakes and dragonesses. Drakons and drakainas can't do this, also drakes and dragonesses can't become drakons or drakianas this way." Ember explains to the three mares as Spike was busy else where getting clean up.

"So that's how Majesty created the drakons. When she tried to force the dragon eggs to hatch as males she must have unknowingly affected the dragons natural ability to change sex with her magic and created a new biological sex in the process." Twilight thought to herself as she wrote down what Ember said.

"That is amazing, I have heard of animals doing that, but I didn't know there was any people that could do that." Fluttershy said.

"This sound painful, very painful in fact." Limestone said.

"Oh, it is, that's why most dragons either do it only once or not at all. Well, willingly that is, it is possible for dragons to force other dragons to change this way, but it is a bit rare to do that." Ember added on.

"Dragons can force other dragons to change sex naturally?" Twilight asks.

"Only if they are drakes or dragonesses, and get other dragons of the same sex to help change another of your sex. A group of dragonesses couldn't turn a drake into a dragoness, but other drakes could for example." Ember explains.

"Hey, I'm back, so who and what is the next dragoness?" Spike said as he walk back into arena.

"Her name is Lightning Dice and she is a lightning xorvintaal amphiptere." Tiamat white head said.

"And that means what?" Limestone ask.

"If I remember right amphipteres are dragons who look like lindwurms but have wings as part of their arms. And I'm guessing that lightning is her breath weapon, but I have never heard of a xorvintaal before." Twilight said.

"You're right about those two things and as for xorvintaals they are a breed of dragon famous for being obscene with games and sports. And they have all kinds of weird powers the most famous of which is their ability to make floating eyes, leak their own poisonous blood from their claws, fangs, and other sharp parts, and they can give non-dragons a little bit of their powers." Ember explains.

"Another breed of dragons? Are dragon breeds common enough that all dragons have them?" Fluttershy ask.

"No, in fact, most dragons don't have a breed of all. But all of the dragons Spike will be breeding do as I as the dragon lord made sure to pay extra for breeders that do have a breed." Ember explains.

"And now that you have some more notes for your book it is time for the fun." Pink head said.

"Lightning Dice come forth!" Blue head shouted.

The doors open and out slither out was a blue hornless dragoness with a purple underbelly and purple frilled going down her back. From the waist down, her lower half was snake like while arms were also wings.

"Hopefully this one doesn't want to use her snake on me too." Spike thought as he watches the dragoness come out.

Behold the enchanting Lightning Dice! Is your will save high enough to resist my feminine charm!" The dragoness said as she did a pose.

"So this one is a nerd." Limestone said as she watches the nerd dragoness do her nerd pose.

"Oh yeah a big one, best on whom Spike took as his wives I figure he had a nerd fetish." Ember answer as look over at Twilight.

Limestone giggle at that.

Suddenly floating draconic eyes appear from nowhere around Lightning Dice.

"These floating eyes will give me plus three on my spot checks as we have sex." Lightning Dice said while doing another pose as her eyes floating around the arena.

"I'm not really sure why you need those? I mean can you even see fro-EEEK!" Spike scream as he felt a large round draconic eye go right up his ass!

"Sneak attack from behind to the behind! It always gets them." Lightning Dice laugh out.

"Why is it always my ass?! Why is always my-Oh, right, it is because I'm a dragon." Spike thought remembering his lot in life.

"Wait? What is this? It seems my search check is telling me that you're a drakon! What fun!" Lightning Dice said

"So you can see with these eyes, but how do you see that?." Spike asks as he felt the eye in him wiggle and move around.

"My eye is right up next to your womb! I have shoved enough eyes open myself to know what a womb looks like without a knowledge biology check. Now, speaking of wombs let get down to the encounter!" Lightning Dice said as unleash her 3D breasts, as in she had three D-cup breasts. She also opens up her bag of holding, but she didn't take out her rod of butt domination.

"Oh, thank the all-dam Pretty Pony she doesn't want to use her snake like the last one." Spike thought to himself before talking to Lightning Dice,"So now that you have your eyes in me how do you want to start this?"

"I want to explore your temple of doom while you explore my shine of fertility!" Lightning Dice said

"What doe that mea-EEEK!" Spike shouted as more eyes were shoved right up his ass.

Catching him flat footed Lightning Dice made her move and grab him in an improved grab. Lightning Dice shove Spike face into her crotch while she shove her tongue deep into his ass. Spike feeling her tongue make its way around the eyeballs in his ass he got the idea of what she wanted him to do. He grabs her waist and started giving her shine a good spit polish.

Spike notices that Lightning Dice taste a lot like blueberry mix with pink diamonds, he also notices that her tentacles didn't grab at his tongue. Instead, it was more like they were brushing it gentry.

Soon he could feel her inter walls closing in on his tongue, and mouth became filled with her sweet juices. As well getting plenty on his face.

"I think you rolled a nat 20 on that!" Lightning Dice said as she took her tongue out of Spike's ass. Only the tongue, the eyeballs not only stayed in, but started to wiggle more.

"Thanks now about we get to the main event right now." Spike barely holding it in thanks to the treatment Lightning Dice give to his backside, and the fact the eyes was still wiggling in him.

"Oh, we could, but I think we should take care of that first. Now here comes my finisher!" Lightning Dice said doing and another dorky pose.

Not that Spike was able to notice that, as at the moment she did her pose the eyeballs started to wiggle, and vibrate far more sure than before! Moving in places in his ass that he didn't even known he had before today, which is how he found out just where his brood pouch and womb was in location in his ass. Thanks the eyes branching off into those locations.

"Oh Celestia!" Spike shouted as ropes and ropes of his thick jelly like semen shot from his twin dicks and hitting Lightning Dice's crotch.

"Wow! You're hitting the front of my pus so hard with so thick semen I can feel it making a dungeoning trip into me right now! I may get pregnant just from this alone!" Lightning Dice said and Spike came hitting her with his cream.

"Well, I'm not paying you for maybes so get those cuntsmashers in your egg hole right now!" Ember says standing up, revealing that this whole time Fluttershy have giving her snake a hoofjob.

"Well I do need that money for splatbooks, so get those twins in here and let's see what ability scores we can roll up together!" Lightning Dice said as she grabs Spike pull him closer to her.

"Are all dragonesses this forceful? And if this is normal, then what are their doms like?" Spike said as line up his twin dicks with Lightning Dice's moist hole. He then started to slowly push his with pass her round lips and into the deepest parts of her love tunnel.

As he did Lightning Dice started to wrap her tail around Spike, when Spike was all the way in her she stop and tighten her grip on him. Spike grabs what he believe to be her hips and started to thrust, causing her to moan and flap her wing arms. Soon he quicken his thrusts as fast as he could as her tentacles lightly warp around his spines and his piston movement started, all the time she just flap her wings.

Soon from hers flaps cause his thrusts the two of them were off the ground by a few hooves, just hovering in the air in the art of love making. Filling the air with their bodies and their moans of pleasure. Then in one final thrust Spike started to fill her cave, causing Lightning Dice to let out a roar! And to start flapping her, causing them to fall as they cum, hitting the ground before they stop cumming.

"Are you okay? It sounded like you hit the ground hard?" Spike asks as finish filling her.

"Don't worry, I was too busy feeling something else then to feel that." Lightning Dice said with a giggle.

Featherbangs is asking the pregnant Blaze and his three fan mares if they would marry him, and base on how they are freaking out I believe the ask is yes.

In the home of Stormy Flare, the mother of Spitfire, the sound of skin smacking skin can be heard. This is because the brave wonderbolt captain Spitfire was butt naked bend over her mother's knee getting her yellow ass turn bright red as her mother spank her like she was still a naughty filly.

"I can't believe my own daughter would do something like that to a married dragon in front of his wife!" Stormy Flare angrily shouted as she mercilessly spank her pregnant daughter.

"But mom, he had two phat thicc dicks! Two phat thicc dicks! And besides all the other wonderbolts were jumping on his ass!" Spitfire cried out as tears rolled down her cheeks.

"The only butt here is the one I'm spanking little miss, and I plan on getting a good close look at the dicks that made me a GILF! Also for swearing, I'm adding a hundred more to your spanking count and I'm going to use Mr. Paddles for them!" Stormy Flare angrily shouted, only stopping her spankings to pull out a large wooded paddle.

"Not Mr. Paddles! Please mommy, not Mr. Paddles!" Spitfire cried right before Mr. Paddles was brought down hard on her backside with a loud SMACK!

"You will understand why I'm doing this dear once my beautiful grandfoal gets here." Stormy Flare said as she continues to use the paddle to spank her crying adult daughter.

Author's Note

Amphipteres have shown up in MLP comics before.

Xorvintaal was a template from DnD for dragons and also a name of a game that only dragons could play. I turn it into breed here to make it fit.
