Riddle me this

Sphinx sat next to Spike in their room, Starlight was busy trying to get Twilight to talk to her, and both the Princesses had headed out on their way to set up the wedding, Sphinx had re-sent invitations with the time and date on it, including a few she had missed the first time around "I honestly had no idea you knew the respective leaders of the Changelings and the Dragons," She had said with a shrug "Reading a sleeping mind usually works but I guess I found the memory and mistook it for a dream," she had then set out to send a letter to Chrysalis about bringing a few female Changlings for an orgy, the response had been very unique "Chrysalis said no promises but maybe, she also said that Changling females can mimic the male organ for some fun but not for reproductive purposes, so I guess once she joins in Chrysalis can take some of the banging for you,"

"I'm...not sure how to respond to that," Spike replied for a moment, "Does that mean she's gonna just grow a dick or is she gonna turn into me?"

"Well, I'd say she could probably do both, I myself would rather only play with you, but I think Starlight might like the idea, and probably some of the random mares who will be showing up for the orgy," Spike looked around the room, the door was locked, and his one window was covered in a curtain that didn't even let the light shine through,

"Alright what do you want?" Spike asked "You don't just lock us in here if you don't want something,

"Spike as much as I want to do what we talked about, it's gonna have to be moved to tomorrow, we have a week to whip you into shape, and when I say you I mean your stamina,"

"What's wrong with my stamina?" Spike asked.

"Spike don't get me wrong being able to go for three rounds in amazing, but I feel if you want to really last threw this orgy where gonna have to push you past that limit, our goal is ten, my dream is twenty," Spike watched as she got a little bigger than him "and since your going to be gathering your energy on the last three days you and I have a lot of work to do," she leaned over and tapped his neck,

"Would you mind taking this off?" Spike pressed on the side and it compressed into a collar, he got up and placed it on his bedside table and moved back to Sphinx, he looked up at her and, as expected, found her naked.

"Alright, nothing fancy, just keep going till you can't" Sphinx lay down on the bed and presented herself "This isn't for pleasure, it's for training,"

"Oh well if that's the case we could go get Starlight and you can watch and keep..." Spike started when her tail wrapped around him,

"Ok stop calling my bluff and let's get going," Sphinx pushed Spike to her and he got to work, Spike placed his hands on her hips and began pumping into her, Sphinx began purring as he did this, hearing this sparked a memory for Spike who smiled, as he kept pumping he moved one of his hands to her belly and began rugging it, the results were instant, her legs locked around him and she pulled him close as she began panting, her Purring intensified, as she began squeezing her girls, Spike moved his other hand and began scratching her belly, the results to that where surprising, her wings shot behind him and her tail winded around his as she got up and pushed into him, Spike ended up putting his hand behind her back and began scratching her back as they pushed into each other,

"Oh I love it when you do that," She purred, "My turn," Sphinx raised her arms and began rubbing Spike's ears, he didn't last much longer after that," Sphinx felt herself filling up and was about to pull away when Spike pushed himself back into here,

"Where are you going?" he asked, "You said we had to keep going till I couldn't," Spike pushed back into her, Sphinx placed her head on his shoulders as he continued nailing her, after a moment Spike looked over at her and kissed her cheek leaning forward enough so she was hanging off him as he continued pumping, he put one hand behind her back and placed the other on her belly again "Let's see how long you can last," He decided as he began vigorously scratching her belly, Sphinxes purring began vibrating through the room as she arched her back, as Spike scratched her belly he leaned forward and began suckling on her left breast, Sphinxs' hand flew to her right one and she began squeezing it, Spike exploded just as milk irrupted from her, Spike got a mouthful and her right hand got some of it, her chest got soaked as Spike swallowed his prize and began drinking it from the source, the flowing of Milk was felt relaxing, mixed with Spike still pumping, closing fast on his third explosion, After a moment Spike noticed the small mess on her right hand and right side of her chest, he stopped suckling and began licking her hand, his toung ran threw her fingers and lay on her nipple before running down her chest and lapping at the milk that was running down, he stopped after a moment as the milk began running a little to low for him to trust chasing, Finally he exploded for a thrid time, Sphinx was breathing heavily as she waited for him to pull out, her squeal indicated to Spike she hadn't expected a forth go,

"Three was the limit yesterday," He whispered as he pushed into her, she opened her mouth, if it was to squeal again or say something Spike didn't know as he leaned forward and stuck his tongue inside her mouth, moaning could be heard as she sucked on his tongue, Spike's fourth go went by as fast as his third one had the day before, after a moment he took a deep breath, still feeling aroused but not quite having the energy to keep going, he finally pulled out and fell onto the bed next to Sphinx, who had been using her magic to keep herself from her own explosion, one Spike had finished she felt the quiver of satisfaction run through her body, she cleaned up the fairly large mess they had made, and with a pop let Spike have his tongue back,

"Give me like an hour," Spike muttered as he placed his hand on her stomach,

"Scratch me there and I'm gonna give you 5 seconds," She warned, Spike picked his hand up,

"Look on the bright side," he said as he looked over at her, "this is only like the third day, imagine how long we're gonna be able to go at it in a year's time," Sphinx thought on that, if three days had gotten him to 4 goes, they could potentially never have to stop once Spike was properly built up to it,

"Spike," She whispered as thought's of the future came to her "When can we have kids?" Spike's response was to point out at his window,

"There's a mountain up there, Once I've bought it and turned it into a massive home for you, me, and any of the rest of this herd, you can have all the kids you want," Sphinx got up and gave herself a set of clothes,

"Go rehydrate and maybe grab a snack, I'll be back in about an hour,"
