"And that is the story of why adult dragons are called wyrms." The purple head of the six headed Tiamat explain to the ponies.

"That story is both highly grotesques in ways I didn't know was possible, and yet sexually arousing in ways that make me ask deep personal questions about myself." Limestone said, clearly confuse by the roller coaster of emotions the story have cause in her.

"...That story leaves so many questions." Twilight said while still thinking of the epic tale erotic horror and sexy adventure she had just heard.

"Nature is so fascinating." Fluttershy said with a smile.

"Good news, Spike's wounds fully heal on their own." Ember said as she enter the arena and flew back to her seat in the stands.

"It is a good thing dragons heal fast. I wouldn't want to meet the next breeder with bite wounds. Speaking of which who is she?" Spike ask as he walk out into the arena.

"Next up is the lovely Cooing dragoness noises the toxic gas swamp landwyrm dagon." The white head said.

"That is a lovely name, what does it mean?" Fluttershy asked.

"It is an ancient dragonish word that doesn't translate well." Orange Head said.

"But it does loosely translate to "She Who Will Violently Violated Your Anus With Her Slimy Tentacles Till You Like It." White Head explain, causing the ponies and Spike to just stare in silent for a moment.

"...That, that a very specific word." Spike said, clearly not liking where this could go.

"Does she really have tentacles? Limestone ask.

"Of course she does, she is a dagon. Those are the dragons that instead of legs and a tail just have tentacles instead. At least six of them anyway, but some have up ten like Cooing dragoness noises." Ember explain, causing Spike not like where this was going even more so.

"So what is a swamp landwyrm?" Twilight asked, clearly trying to change the subject.

"Landwyrms are a breed that can adapt to and take control of natural environments." Pink head explain.

"The swamp part is just because she has control over swamps." Purple head explain.

"We better call her out now so she can start the tantacle violation." Blue head said

"What?!" Spike shouted.

"Cooing dragoness noises it is time for the tentacle fun!" Yellow head shouted, which cause the door to open.

And from it came crawling out an green dragoness with ram like horns and frilled on her head, who had ten tentacles where her legs and tail should be, also she had no wings at all.

"So you're the stud I have heard so much about, have to say you're cuter then I thought you would be shortie." The tentacle dragon said to the smaller Spike.

"Thank you, hmm Failure cooing noises" Spike said poorly.

''Ha, ha, ha, just call me by my nickname Green Tentacle, everydragon else does. Now then why don't we get down to business and get to to rutting." Green Tentacle said, while tentacles started to wiggle.

"Well is there anything you want me to do help warm you up?" Spike ask the large tentacle dragoness.

"Oh don't worry foreplay." Green Tentacle said she wrap her green tentacles around Spike's legs, arms, and even his tail. "In fact all you have to do is lay there and take. Take hard!" She added while releasing her three C-cup boobs and puss.

Spike had seen enough of Fluttershy's hentai to know where this was going, but before he say anything to stop he force right onto his back while a slimy green tentacle was forced down his throat!

"Oh nice! You fire breathers always have nicest toasty warm holes to play with." Green Tentacle said with a lick of her lips as she shove two of tentacles right into Spike's toasty warm anus.

"This is just like scene from one of Fluttershy's porn mangas and animes." Twilight said as she wrote down what she was watching.

"It is called hentai, and so wonderfully is like them." Fluttershy happily said, while watching the wonder that was happening in front of her.

"So, did she get her name because she does this, or does she do it because of what names means?" Limestone ask as she watch the father of her unborn foal/or whelp yet again being anally violated by a larger dragon.

"That is good question and I don't really know the answer to it." Ember said as she stroke her snake while watching the tentacles go end and out of Spike.

Spike, meanwhile, was feeling what it was like to be a magic filly. He could swear he could feel the tentacle in his mouth and the two in his ass meet up his stomach. Naturally this force his twin Richards came out for all to see.

"Looks like you're big where it matters at least shorty. Here, let me give you a helping tentacle." Green Tentacle said as she took one of her free tentacles and wrap it around Spike's dicks.

Spike felt the slimy tentacle squeeze and pull his penises, while other tentacles were being used to violently thrust and wiggle in his dragon booty. The feeling of being stuff full of tentacles like he was a sailor scout combine with being jerk off was to much for the lone magic filly and he quickly let out his milk! Getting the green slimy tentacle even more slimy.

"Oh my, that not where that is suppose to go, that stuff is suppose to go in my roper dungeon!" Green Tentacle said while licking her lips. She quickly remove her tentacle from Spike's little spikes, and then use only two free tentacles to put herself on top of Spike as well as in her! All with out removing her tentacles from Spike.

"You know what would really make this perfect is if you were dress up as a school filly. I don't know why but it just seems right, however I do have close second to that." Green Tentacle said right she took her only two free tentacles and slam them right up her own ass and started to violently thrust in and out just like she was doing to Spike's poor butt.

Now Spike could only feel her own inter squeezing his dicks like her outer tentacle did earlier but he could swear that he felt the tentacles in her squeeze his dicks as well! All the while the two in his own ass as well as the one in his mouth were thrusting in and out of him!

The cooing name dragoness meanwhile started to moan and growl in pure both from the piston movement of the two dicks in her as well as the tentacles in her ass! Plus the pleasure she got from violating Spike's ass, something of which he was sadly getting all to use to lately. Thanks to all the pleasure she was getting, and giving to Spike in way, in wasn't surprising when their shared orgasm cum upon them.

Spike was soon filling the tentacle monster that was using his ass as an onahole, filling her tentacle swamp his fresh seed. Causing her to roar out loud with pleasure.

"I swear there is nothing like the tight hole of a fire breather, especially a short one like you! If it wasn't for all the other dragonesses waiting till turn with you I would just use all day to make sure your seed took!" The accurately name dragoness said, and Spike was very grateful she wasn't the last one of the day just for that reason.

Meanwhile Somnambula is teaching a class on sex yoga.

Deep in the heart of one of Equestria's hydroelectric dams Star Swirl the Bearded is being giving a tour by the kiang that runs it.

"This is amazing! Back in my day I would have never dream something like this place could be possible!" Star Swirl said in wonder at the marvels he was seeing.

"I'm so glad you think that sir, and I have to say it is a honor that a great hero like yourself decided to visit us of all places. And I know you must get this a lot but I would love to hear what you think of our era." The kiang said to the traveler from the past.

"I would be happy to my fine fellow, but for I now I just have to know just how much power a marvelous place like this is able to generate." Star Swirl said to the kiang.

"Why I just so happen to have the exact numbers right here." The kiang said as he took a piece of paper from his pocket and hoof it over to Star Swirl.

The elderly wizard took the paper and with one look his jaw drop in pure amazement.

"You're able to generate this much power daily?! In my day you would have to draw out the life force of whole villages to get anywhere near this level of power!" Star Swirl shouted in surprise.

"Well then I guess you will be even more delighted to know that our dam is one of the safest in all of Equestria, in fact in been almost a year since our last work place accident and that the last we had was just somepony falling down the stares." The Kiang said with pride.

"Unbelievable, if I had this much power for just one day I could....I could do it...I could finally do it....In fact I wouldn't even need to change the spell that much...and no living thing would get harm...I can do it, yes, Yes, YES! After all this time it is finally possible to give it back to her without harming anything! I can give it back to her! " Star Swirl shouted in way that all those that heard could tell that this was a stallion who after long searching as finally found the answer to a question he long ago thought was impossible to answer.

"Excuse sir, but return what to whom?" The Kiang in surprise at seeing one the face of one of the most powerful wizards Equestria has even know light up like a foal being giving candy for the first time.

"I can return Mistmane youth to her!" Star Swirl shouted in joy.

Author's Note

Landwyrms are type of lesser dragon from DnD

As far the dagon type dragon, well look this kind of body plan for dragons have gotten semi-popular almost some and I wanted to add in it. I decided to call it dagon because most people have only called it kraken before but I think this is a better name for this stye of dragon.
