"So that normal courtship rituals, but a lot of dragons feels that they are a bit old fashion." Ember happily and proudly explain.

"That why dragons used to lock up maidens and gentlecolts? That really changes those old fairy tales." Twilight said still in a bit of a shock from what she just learn.

"Most of those things sounds painful and illegal." Fluttershy said, clearly not understanding the finer points of dragon romance.

"So just how long do you keep them lockup before you're allow to force them to married you?" LimeWtone ask, causing the other two mares to turn and stare at her.

"What? Some of those ways sound a lot easier, and faster then how we do it." Limestone said.

"I'm all clean up and ready to go! So who is next up?" Spike said as he enter the arena.

"That would be would be Volcanic Death the catastrophic lava wyvern." The purple head said.

"I better go get her." The orange head said.

"Be right back darlings." The white head said as Tiamat got up and left the arena.

"Volcanic Death the catastrophic lava wyern?!" Spike said in shock and surprise on hearing he was about to rut what had to be very dangerous dragon.

"Oh my, she sounds scary." Fluttershy said.

"She must be a tough bitch if Tiamat has to get her ass instead of just calling her like the others." Limestone said.

"What exactly is she?" Twilight ask with notebook ready.

"Wyerns are the dragons who have, legs but their arms are their wings. She spits lava for her breath weapon and the catastrophic dragons are a breed called that for two reasons. The first is that they look like they are made of their breath weapon, so she looks like she made of lava, and the second if they want they can basely cause what they are named after with their breath weapon. As for why Tiamat had to get her, well you're going to see for yourself soon enough." Ember explain.

This cause Spike to get nervous, this Volcanic Death sounded terrifying. She clearly must be a fearsome dragoness, and that was what he was thinking when he heard the arena door open. And out came Tiamat with the catastrophic dragon.

There she was, Volcanic Death. A fearsome looking dragon that seems to be made of pure lava!..And she was strap into some kind of swing set being carried by Tiamat?

"Here she is, enjoy!" The pink head said as Tiamat place the swing set down.

Spike took a look at Volcanic Death, she had her arm-wings, legs, and tail tried up with straps, and was being hung from the swing set by chains. She had a kinky blind-fold on with a pair of kinky noise cancelling ear muffs, and what was clearly a dildo gag strap in her maw. On her C-cup breasts were nipple clamps with weights hanging off them, some kind underwear harness that was keeping a dildo her ass. Which also, thanks to clamps, kept her rounded pussy wide open, and had what look like a chastity cage lock on to her snake.

"....Um, What is going on here? Did, did she agree to this?" Spike ask turning to Ember and also to Tiamat who was taking her seat behind her sister.

"Agree?! She strap herself into that thing!" Pinkie head said.

"I watch her do it too, and still have no idea how she did it, but did it." Yellow head said.

"She is really into bondage, and demands to be tired and helpless for all her breedings." Ember added.

"You really got some kinky ones to get yourself some kids, any reason why?" Limestone ask the blue queen bitch of dragon kind.

"These dragonesses job are to get impregnate for money, it takes a certain kind of mindset to go into that line of work. Besides I paid extra to get some of the best breeders out there, and they can afford to make demands." Ember explain.

"Point taken." Limestone said.

Spike turn back to the larger dragoness, the one who completely tried up and at his mercy. He could do anything he wish to her, anything at all and she wouldn't be able do anything about it. She was completely helpless, she couldn't even shout for help.

So, Spike kneed down and give her wide open hole deep Prench kiss. His tongue filled her hole, and her tentacles grab at his tongue. He could feel the dildo in her ass vibrating, causing her tentacles to vibrated as well. He kind of like the feeling, but wonder if that combine with her pussy lips wide open it would make it a bit hard to her off just from his normal oral technique.

Spike decided to test what he learn about dragonesses ,and used his fork tongue to grab one of her coochie tentacles. Using the twin tips of his tongue he started to play with the tentacle, giving it a light pinch before rubbing all the way down to the base. Then he moving on to the next tentacle and did the same thing, judging by how the dragoness' body was reacting he believe she was enjoying it.

Soon her open hole starting squirting her spicy lube while her caged snake tried to shoot some lube out, only for it to drip down the cage. Spike took a taste of the spicy lava color lube before standing back up to make the most of it. Despite being larger then him, Volcanic Death was strap up in a way that fully allow Spike to make used of her cunny while he was standing.

Spike took a bit of time to coat his twins in the lava lube, or at least their heads. Then buried them deep in the living cataclysm in one go!

Looking at her weighted clamp nipples Spike got a idea, he grape the left and right weights with his claws, and the middle one with his tongue, and pull down. Not hard enough to hurt, but then again these were still weighted clamps on her sensitive nipples so it probably still did. But he figure she must like this kind of thing otherwise she wouldn't have put them on herself if she wasn't. And base on how her snake wiggle around in its cage it look like he was right.

It seems these pulling was enough to cause the volcanic dragon to erupt as Spike felt her lava tube do its best to close down on him. She sprayed her spice all over Spike's crotch as Spike filled her with his own lava.

"You know this makes me wonder, if she spits lava and looks like she is made of lava does that mean there are catastrophic dragons that look like they are made of fire or ice?" Twilight ask as her husband bred the living lava in dragon shape.

But as she turn to the dragon queen to get her answer she saw that Ember was much to busy enjoying having her snake and Fluttershy making out to ask the purple pony princess.

Meanwhile Shining Armor is getting a train run on his ass.

"Now lets see, what would a great place to take Spike to breed a lot of mares." Luna said to herself as she look over a map of Equestria.

"Why must they be mares my highness?" The loyal Kiditz ask the ruler of the night.

"Because we need more royal dragons, and while it would be fun to watch Spike bang the ass of a few stallions we wouldn't get any whelps from that." Luna answer her loyal servant.

"That wasn't what I was getting at my lady. I mean, why does he have to breed only ponies, why not the females of some other race like said griffons." Kiditz ask the princess of the night.

"Griffons you say? That is it! I'll take him to Griffish Isles!" Luna said happily as look at the griffon city on her map.

"The griffon city we bought after death of the last true griffon king?" Kiditz ask.

"Of course, it is perfect. They are always trying to get more in common with the rest of Equestria and this will do it." Luna said.
