After taking some time to pleasure his wives and fillyfriend. Spike and said group, along with the now jelly legged Ember, went to meet her sister Tiamat. As they went they let Ember lean on them as she still had some trouble walking.

"Are you sure we should be meeting your older sister like this? I could at least put on some pants." Spike said, pointing out that he was still naked while the others were allowed to get dressed.

Ember smirked as she leaned on the naked Spike. "No need, you wouldn't be wearing them for long anyway sense Tiamat is the drakaina I'm giving to you."

"You're giving your sister to Spike? That’s a bit strange isn't it." Limestone said.

"Isn't that how you started dating Spike in the first place?" Twilight said.

Spike shock his head. "I don't understand. Is your sister one of these breeders? And what is a drakaina anyway?"

"Sorry, I often forget you don't know these things. When a dragoness of high standing gets herself a drake, or in your case a drakon, concubine she gives them a drakaina of their own. A drakaina being a special kind of dragoness, and as to how they are special I'll let Tiamat explain that one. Speaking of, she should be around here somewhere." Ember explained as she looked around the area.

"Ember, is that you!" an unseen voice rang out.

"Hey did you bring your double d drake with you?" A different unseen voice rang out.

"You better have, cause I have all the breeders waiting for him!" Yet another unseen voice rang out.

"And they are a bit annoyed that he is a day late as it!" Somehow another voice rang out.

"Yeah, it isn't like it is every day these dragonesses have a chance with a double d!" You can probably guess about this one.

"So he better be ready to breed!" One last voice rang out.

"Yeah that her right now. We are over here!" Ember called out.

"Wait, if one of those voices were Tiamat then who were the others?" Spike asked

"Those were all Tiamat's voices." Ember explained.

"What? But there were six different voices, how can that bee-BY CELESTIA'S GIANT BOOBS!" Spike screamed.

"BY LUNA'S FULL MOON!" Twilight shouted in surprise.

"BY ERIS' GIANT DICK!" Fluttershy yelled in shock.

"HOLY FATHERRUTTER, THAT’S YOU SISTER?!" Limestone joined in the yelling as the group gazed in shock as from behind the cliff came the largest dragoness any of them have ever seen.

What Celestia was to normal mares this dragon was to normal dragonesses. She easily towered over every single dragoness any of them had ever seen. The crimson red dragoness had a dark purple underbelly and stood on feet with three web-toe with a dew claw on the heel. Each toe topped with a golden claw. Her digitigrade legs were thicc and shapely with equally thicc thighs that connected to large egg bearing hips that rivaled those of Celestia herself, and in-between those hips was a large round dragoness' pussy. Even larger then Ember's when scaled to size.

If this dragoness was the size of Celestia then her huge thicc jelly ass and plump belly would equal those of Celestia, but being larger made them look even bigger. She had three huge breasts topped with dark red nipples. Each as big as one of Celestia's heavenly breasts. All four of her arms were thick and shapely with sculpted muscles, and her large hands each had four web fingers with a golden claw. Her wings were huge and each segment of her wing had purple membrane with a green eye spot, while her wing fingers and thumbs ended in golden claws. Her long tail split into three ends, with one ending with a golden curve blade. What truly made this dragoness different than any other was the fact that she had six heads! Each one completely different from the others!

The bottom left head was orange, with a long neck and yellow scaled underbelly. It had a short snout with a pair of golden tusks and some kind of shield-like curve plate growing from the top of its head. There was a row of needle-like spines down the back of its neck that were mostly the same yellow as her scaled with bits of red and pink on them. Finally she sported a pair of bright emerald green eyes.

The lower middle head was a snow white with dark purple underbelly scale’s running down it’s section. This head looked more like a normal female dragon head with a pair of pure black horns sticking out from the back. The most unique aspect of it was that it had short tuffs of purple curly fur running down the back of its neck with yellow and blue in lighter shades of stripes. The head sported a pair of bright blue babydoll eyes.

The bottom right head was yellow with a pink underbelly. It had softer, rounder features than the others. With a pair of fin-like ears on her head, snakes for hair, and soft round ridges going down the back of its neck. The ridges and snakes were mostly pink but there were some green, light blue, and darker pink ones as well. This one seemed to be a heterochromia. With it’s left eye being blue and its right eye red.

The upper left head was pink with a darker shade of pink underbelly. It had a short snout like that of a rhino. Complete with two horns growing from the snout that were both dark pink with yellow, orange, and blue stripes on them. It also had a pair of saber fangs jutting from it’s upper jaw, with a pair of smaller, but still large fangs behind them on her bottom jaw. It also had ram-like horns the same color as the rhino horn, and cat-like ears on the side of its head. Down its back ran hexagon like bone plates, and its eyes were a dark blue.

The upper middle head looked a lot like Spike's head in his giant size form, but more feminine, and it had curved a horn growing from its forehead. Its underbelly was also a darker shade of purple, and the frills on its head and back a darker shade of purple with stripes of yellow, pink, and a different shade of purple breaking it up. Its eyes were also a deep purple.

The upper right head looked a lot like Ember but not as scrawny. It’s belly was a rainbow of colors and it had a mane of rainbow color feathers with them running down its back. Its eyes were also a deep shade of red.

"It seems my beauty has you stunned."The white head said with a giggle.

"Not that I can blame you, it isn't every day you see chromatic leviathan drakaina princess." The orange one said.

"Especially one with such divine build like me." The blue one said.

"Excuse me ladies, but why are you all naked?" Twilight asked as she blushed deeply.

"It’s lady darling, not ladies. I take it you’ve never talk to a dragoness with more than one head before?” askedthe white head

The entire group save Ember shook their heads.

"Well, let's make it clear that I'm are a single individual." said the white head.

"And to answer you. I'm naked because I'm a drakaina about to mate with her master for the first time." The purple one said.

"What does that even mean?” question Limestone. “You say you're a chromatic leviathan drakaina like we are supported to know what that means."

"And what is with this master talk?" Spike asked as he scratched his head.

Tiamat looked at her sister clearly confused by Spike and the ponies lack of understanding.

Ember looked up to her sister and shrugged. "I told you they were coming to learn more about dragons. Which they know almost nothing at all about. I also thought that you might wanted to be the one to explain what you are and what this is about." Ember explained to her older many headed sister.

"Well, to start a chromatic dragon is what you call a dragon with multiple heads. Each one is a different color with a different breath weapon. Other multiple headed dragons normally have their heads looking the same with the same breath weapon. And in case you're wondering, my breath weapon is fire." The purple head said.

"Ice." The white one said.

"Lighting." The blue one said.

"Acid." The yellow one said.

"Sonic scream." The orange one said.

"Laughing gas." The pink one said.

"I should also add that it is a dragon tradition to name any chromatic dragoness with five or more heads after Queen Tiamat. The first dragon lord and first known chromatic dragon." The purple one said.

"Leviathans are dragons who can breath underwater. We leviathans also normally have fins and web claws as you can see." The white one explained as she lifted her foot to show off her webbed feet.

"Leviathans can also shoot laser beams from our eye-balls!" The pink one said before showing she was telling the truth by shooting laser beams from her eye-balls and blowing up a nearby rock.

"Now the drakaina part. That is the most important thing about me." The blue one said.

"Even more important than being a princess." The yellow one said.

"Is being a drakaina anything like how Spike is a drakon?" Fluttershy asked.

"He’s a what now?!" The heads say together as they turned to their smaller sister.

Ember smirked. "Turns out that Spike is a double dick spellscale drakon."

Tiamat eyes widened in disbelief.

"Holy dung! You really do have an eye for quality sister!" The white head said.

"A double d spellscale drakon and a chromatic leviathan drakaina! Can you just imagine the dragons we will make together!" The yellow one said.

"Wait, so you are one of these breeders?" Spike asked.

All five heads broke out laughing.

"No dear master, we are so much more than that." The blue one said.

"Now you may have noticed that my fun parts are out, and that right there is the first sign of a drakaina. We can't hide our fun parts like other dragonesses because we are always in mating season. Meaning we are far more fertile and lay more eggs at once then other female dragons." The yellow one explain.

"But what really makes us special is our womb! You see a drakaina's can do things a normal dragoness' womb can't. One of those things being instead of just wasting a perfectly good load of sperm when after already being inseminated can we save it for later." The Pink one said.

"Another thing our womb can do is we can mix and match sperm samples. To a degree at least. For example after I rut you I will save most of semen for later use, but let's say I then go on to rut an earth pony later. I can then mix some of the genetics from his sperm with yours to create a dragon offspring that is mostly yours but will have some traits from the earth pony." The orange one said.

"Because of this amazing ability it is the sacred duty of all drakainas to increase the genetic diversity among dragon kind by mating with as many different creatures as possible! In fact, if a drakaina is lucky enough they may even spawn a whole new kind of dragon." The blue head explained.

"However, the key term there is dragon kind. In order to make sure that brood of a drakaina are all dragons and not half-dragons or dragonborn there are traditions in place. So when a drakaina is hatched they are taught from hatching how to be great mothers, and once old enough how to be amazing lovers." The white one said as she batted her eyes at the end.

"While also being kept in chastity until they find a master, aka a dragon stud that will be able to make sure their bellies are filled with growing eggs and that their nests are even fuller. And sense we are so rare it is normally the job of high ranking dragonesses to name their husbands as masters. To help make sure we get the best dragon we possibly can. And I should also add that another trick of a drakaina's womb is that drakainas have more than one, In fact I have six. Which means drakainas can get pregnant even while they are pregnant. It also means that as long as you do your job as my master this will be the last time in my life I will be without eggs growing inside of me." The purple one said while giving Spike bedroom eyes.

"Wait, you want to spend the rest of your life being pregnant and having kids? I mean I can understand wanting a lot of foals. I’ve always wanted a lot myself but isn't that a little too much?" Limestone ask

"I think I better explain this one sis,” said Ember as she waved at her older sister to step down as she took over. “You see Tiamat here won't be raising all of the whelps herself as this is a public good for all of dragon kind. While as her master Spike will have first dibs to any eggs from Tiamat as he wants, fallowed my myself and Spike’s wives, it is normally other drakes and drakons who wish to have whelps of their own to raise who will be the primary caregivers most of the hatchlings. Of course Spike and Tiamat can also chose who is allowed their whelps, and sense Princess Celestia wants more dragons in Equestria this will be fast way to do too." Ember explained.

"I guess that makes sense.” said Spike. Now having learned more about his kind in a day then in his entire lifetime. “So I assume I'm supposed to rut you now?”

"YES! " All the heads screamed at once as they started to make their move to him.

"Hold it! Hold it! If we are going to do this I better grow a bit first, otherwise, well... I'm well equipped but I'm not that well equipped." Spike said as he pointed to the dragoness giant pussy.

"Fine just hurry up and grow already." Tiamat said with all her heads again.

"I didn't know you knew how to grow. I don't even know how to do that yet." Ember said. Impressed by Spike’s magical knowledge.

"Can't all dragons do it?" Spike asked.

"Well all dragons can learn to change size one way or another, but that doesn't mean all dragons do learn how. Some dragons just never bother to and some are simply horrible at it." Ember explained.

"Hey enough talking already. Let get to the rutting!" The blue head said

Spike nodded and began to reach down to feel his primal instincts. As he did Spike began to grow, and change. His plantigrade legs became digitigrade legs, his shout grew longer as did his fangs as another pair fangs grew behind his main ones. His features grew sharper and his neck became long and serpent like. Spike stopped himself from growing once he was as big as Tiamat and it was then that he realize that she as well as Ember was looking at him in utter bewilderment.

"What’s the matter? Did I break something?" Spike ask.

"Spike you're a kaiju?!" Ember shouted in surprise.

"Holy dung! Do you know how to pick them Ember!" The pink one happy said.

"We should talk to Beryllinthranox. Maybe we can find her nice drake with eyes like this." Purple one said.

"What is kaiju?" Twilight asked as once again pulled out her notebook and began to write.

"Which most dragons grow in size they don't change like this. Those that do are called kaiju. When a Kaiju dragon grows he doesn’t just change, he becomes incredibly strong and durability, and even his breath magic becomes more powerful. They are also able to heal faster too." Ember explained.

"It also means he is one of most viable dragons alive! Now lets make with the breeding!" The pink head said right before Tiamat pounced on Spike!

Spike was barely able to act fast enough to catch the heavy set dragoness without falling over, and as soon as did he felt Tiamat’s lower arms go down to grab his ass while all six of her heads either kissed her or licked him while her upper arms pulled him closer.

"Don't you want me to warm you up first?" Spike was able to ask in between dragon kisses.

"Maybe next time! Right now I want the double d!" The yellow head yelled as two fingers slipped into Spike's ass. Causing his cave to go up and his double dragons to come out.

"Holy rut!" Spike shouted in surprise as the fingers left his ass.

"Like I said earlier darling. I was trained how to get a lover up and going." The white head said as Tiamat grabbed Spike's cocks with one hand and guided him right into her pussy.

"OOOOHHH, YYYYEEEESSSS!" All six heads of Tiamat moaned as the smaller ponies and Ember got out of the way as the two large dragons "wrestled" with each other.

Spike felt himself being pushed more and more back as Tiamat’s hungry coochic tried to get even more of the lovely dragon meat inside of it. He could feel her tentacles, tentacles that were longer and stronger then either Ember's or Eris', trying to keep his mare breakers inside of her as they started their piston movement. It was taking all of Spike’s strength had not to be pushed down by the cock drunk dragoness.

As Spike’s strength gave out he decided he wasn't going down without a fight. Acting quickly Spike made himself grow some more. Not by much, but when Tiamat felt Spike already well size dongs grow even bigger inside of her, all of her eyes started to roll back into all of her heads.

Seeing that the mighty Tiamat was weakened, Spike moved in for the kill, with a mighty strike Spike shove his prehensile as deep into the leviathan's ass as he could. As he did it all six heads started to moan and roar in pleasure. Giving Spike the leverage he needed to get the large dragoness on the ground, ending their grapple.

Now that she was on her back and Spike’s claws were free he continued his assault. He grabbed her giant left and right nipples with his claws and started to message them while he took his snout to her middle one and started to sucker. As he did he was shocked to find that Tiamat was also lactating. Earning him his first taste of dragon's milk.

"Huh, has a very complex flavor and is less sweet than a pony's milk." Spike thought as he drank.

As for Tiamat; she was beyond thinking. Right now all she could do was feel. And soon the feeling grew too much for her. She started to water the ground with her love nectar as Spike filled her with his rare cream.

"That growing ability looks like a lot of fun. Maybe I should learn it after all." The red faced Ember said as she watched her older sister get breed.

Meanwhile Gallus and Silverstream were being birds of a feather and flocking together.

"Now don't forget ya second cousin Apple Delight." Granny Smith said as Applejack wrote down a list of names.

"I already got her down, now what was cousin Sugar Apple’s new address?" Applejack said as she wrote.

"Darn if I know. See I told ya that the plowing of the apple pots should have happened after the wedding when all the apple’s were in one place." Granny Smith said.

"Granny I told ya we were busy. This whole stud business can keep Spike busy ya know." Applejack said.

"All the more reason for ya to have done this sooner! I'm telling ya will give a bigger boost in his breed numbers then any of these other events he’s been doing. After all, ain't no pot more fertile then an apple pot." Granny Smith answered back.

Author's Note

Tiamat is the name of Babylon goddess said to be the mother of all dragons, monsters, and gods as well as the first goddess of salt water. She is best know now of days from the game Dungeons and Dragons where she is the goddess of chromatic dragons, evil dragons name after colors.

Drakaina is ancient Greek for dragoness.

Leviathan is one of three ancient giant beasts from the bible said to one day fight to death at the end of days. There one beast for the land, one for the sky, and one for the sea which is the leviathan. The leviathan to the ancestor of all dragons and unlike the other beasts there used to be two of them before God killed one of them to stop them from breeding more leviathans.
