Spike was busy making himself a rainbow quartz sandwich on a quiet day alone at home. Six of his eight wives were called to Canterlot castle for some reason while Starlight and Trixie help were doing something with the students. Of course the fact that all eight of them told Spike to just stay at home told him they were either planning something or already had something planned for him, but that was something for future Spike.

It had only been a few days sense Celestia made the big announcement that she, Luna, and all of Spike's wives were impregnation by Spike and things had been a bit busy since then. Reporters wanting to talk to them, nobles wanting to talk them, family finding out and freaking out. Then there was anti-dragon protesters who came by the castle. Lucky all it took was for Spike to growth to giant size to chase them away, but still. He’s rather not have to deal with his problems using intimidation. To top of all he still had to get ready for some kind of apple family tradition where he had to plow a bunch of apple pots for some reason. So yeah, a little bit of quiet time was something he really needed.

"Let's see, where is that jelly?" Spike said while rummaging through the pantry .

"May I suggest some durian jam instead? I find it goes so well with rainbow quartz."

“Oh, thanks for the tip E…” Spike blinked. He pulled his head from the pantry and turned around to see the draconequus of chaos behind him.

Eris was a giant compared to most other creatures, easily taller than even Princess Celestia, which meant she was of normal height for a dragoness. Of course she was not built like Celestia in anyway. While Celestia was the very definition of the world thicc Eris on the other hoof had a long noodle like body, almost like that of snake standing upright. She also had three small breasts, like a dragoness, an udder like a minotaur right above her crotch, and a short black mane which really made her thick white eyebrows stand out, and -

"I think they get it! So can we stop describing my beautiful body and get back to the story! I'm already beginning to get a woody and I don't mean the doll." Eris shouted

"What?" Spike said very confused.

"Oh never mind that, now, how is my favorite fun size dragon doing today?" Eris asked.

Spike shrugged. "Just enjoying a quiet day at home while I can. When the foals get here I don't think I'll have to many days like this for a while, especially with as many as we're going to have."

"So your waifus told you about our little talk huh?" Eris said as she proofed up some body pillows of Spike's wives.

"Yeah Twilight has been trying to put some plans together involving how many foals we're going to have. So what brings you here anyway?" Despite being a creature of chaos it was actually rare for Eris to pop into a place without wanting something. Though what she wanted was often random.

"Well while you were busy knocking up the wonderbolts. Me and the fillies were having a little talk about why I haven't taken our little draconic sex toy out for spin yet. And after a little talk with them I decided it is time to make full use of my tiny concubine." Eris said with a smile.

Spike has been dreading this moment, knowing full well it was coming and there would likely be little he could about it. Well, little he would actually do about because he couldn't bring himself to say no to a mare about something like this, especially one who was in for the pleasure rather than because she’s been ordered by Celestia. Maybe it was because of the breed of dragon he was, or maybe it has to do with the fact he was secretly raised to be the ultimate concubine by Celestia.. Either way the willingness to breed any who asked was part of him.

Of course what really bothered Spike is the whole reason why he was dreading this moment was because Eris had a penis. As proud penis owner himself Spike knew full well how creatures with fully working penis loved to use them. Especially when they had a monster of a dick like Eris did. Sure Celestia and Luna had put plenty of things up his ass, and he had rutted stallions before, but Spike had never taken a real dick. And he wasn't looking forward to the day he took his first one.

"So what took you so long?" Spike asked, hoping to drag out the time a little bit before his buns were frosted.

"A few things really, one of which being that make when I was raised a mare that had to pay the mothers of the stallion she wanted to rut. Especially if she was going to keep him as her own." Eris said

"Well that isn't normally done now days. So you're in the clear there." Spike said

At Spike's Parents House

"Honey, why are their bags of bits in the living room?" Night Light asked.

"Eris came by to pay for Spike." Twilight Velvet answer

"Really? I thought Princess Celestia already paid for him." Night Light said

"She did, but I guess Eris just wanted to make sure." Twilight Velvet explained.

"Wow, we earn a lot more with Spike then we did with Shinning Armor. If our new one is a colt do you think we can even get more for them?" Night Light ask

"Hmm, Maybe? I mean we are three for three in terms of raising children that become royal heroes so I bet royals and nobles from all over the world will be wanting to add this one to their herds if it is another colt." Twilight Velvet answered.

Back at the friendship castle

"Kind of wish somepony told me that before, oh well, too late now I guess. So are you ready for our love making or should I set the mood?" Eris said as she proof a heart shaped pink bed into existence, then poof off her clothes.

Spike took one look at the monster that Eris had for dick. He knew full well that no mood would help get him ready to take that but he also knew what his answer would be."I'm as ready as I'll ever be."

"Wonderful! Oh Spike one thing, make sure to address me as onee-chan." Eris said with a lusty smile.

Meanwhile Ponyville local prev Pinprick was trying and failing to get into the pants of visiting unicorns mares Moonlight Raven and Sunshine Smiles. But that has nothing to do with us so to Canterlot Castle we go!

"So High Winds wants to know if I could get her an updated Draconomicon, and since Spike knocked her up, I figured the least I could do was ask you about it." Rainbow Dash said to her herd sisters as they waited for Cadence to show up.

"Now that you mention it would be a great idea to make an updated Draconmicon. Especially sense Spike disproved most of the theories in the old one the day he was hatch." Twilight said

"And sense there is going to be so many mares with little whelps on the way it would make sense for them to know a few things about dragons." Applejack added.

"Yes, yes, we can talk about making this book later. Right now I want to hear more about how Spike bred all of the wonderbolts." Luna said

It was then that Cadence entered.

"Sorry I'm late, Flurry Heart needed a new diaper." Cadence said

"Well now that we are all hear we can talk about our plans to explain the royal dragon breeding program to other kingdoms." Celestia said
