"I'm coming, mom." Twilight Sparkle was laying on her side, two foals eagerly snuggled up between her back legs. She watched their tails flick excitedly every now and again. "You really think I would miss your wedding?"

"But the foals…" Twilight Velvet gestured to the two, happy little ponies. "And you still need to recover some more before-"

"A train ride and I get waited on hoof and hoof. I would have an easier time looking after them in the Crystal Empire!" Princess Twilight leaned down and nuzzled one dark-colored flank. "I'm coming, and that is final."

"Twilight Sparkle! How dare you… It isn't going to work, is it? You are too big for me to use that on anymore."

"Nope. I am a mother too now, and I learned from the best." Twilight Sparkle leaned up and rubbed her cheek with her mother's.

"Twilight! Is something up with Rarity? I went to see her to order a fancy hat but she was wearing a heavy cloak and her voice sounded… off." Gel poked his head into the library, knowing just where his wife would be. "Oh, sorry mom, if you are busy…" His grin was wide as he addressed Twilight Velvet, but he got a returning smile.

"No, I have come to realize the error of my ways. I raised my filly to be smart, strong-minded, and above all, just as head-strong as I am." Twilight Velvet trotted past the stallion. "Good luck, son, you are going to need it."

Gel slipped all the way into the room and closed the door behind him. "Argument?"

"Not really. More just both of us realizing we are more alike than different." Twilight gasped and winced a little. "Ow ow ow, do changelings always have their teeth at birth?"

"Don't really know, I never grew any." Gel shrugged and curled up beside Twilight. "But you really should go and see your friend, I think she might be sick or something, maybe take some of Starry's soup?"

"We are going for a trip, tomorrow." Twilight announced, sighing when both foals, noticing one of their fathers was present, finished their feeding, burped loudly and wobbled over to Gel.

"Your parent's wedding?" Gel rolled to his side as two little ponies assaulted him. Twilight just nodded in reply. Holding up his forehooves, Gel watched as the foals tried to bop them with their own, their balance sorely tested with the task. "Applejack won't be able to come, you know." He spared his attention to watch Twilight's reaction.

Sighing, the alicorn nodded. "Her farm cares not what ponies do, only the seasons matter." Twilight fetched the soft towel she kept nearby and cleaned herself up. "Well, first thing's first, let's go see to Rarity."

Both parents froze, staring at Winged. The filly, growing tired of missing the deceptively agile and huge hoof, flowed her foreleg at an odd angle to hit it, before restoring her normal appearance. The two adults turned to look at each other, both grinning like fools. "She really is yours." Twilight got up, stepping over to kiss Gel on the snout before levitating a squirming dark filly to her own back, and a unicorn colt to Gel's.

Carrying the big bowl of soup, Twilight walked beside her stallion. "Applejack still wanting to have a foal?" Gel nodded to her, the sleeping colt on his back splayed out and snoring. "She is a brave mare, after seeing what I went through."

"You think AJ hasn't seen birthing before?" Gel snorted. "She grew up and runs a farm, remember how she was with Fluttershy's labor? She knows what she is going in for. Did you offer to help?"

Twilight almost snorted. "But I'm… silly, of course I could be a stallion for her." The alicorn shook her head. Lifting a hoof, she tapped on Carousal Boutique's front door.

The door opened a fraction and then closed again. "Nopony is here!" Rarity's voice was insistent.

"Rarity, what's wrong? Let us in so we can talk." Twilight tapped on the door again. "Don't make me teleport, I'll spill the soup."

"Soup?" The door opened a crack again and both royals saw the cowl hanging far over Rarity's face, but rather than the unicorn's magic lifting the soup from Twilight, instead her forelegs lifted as if to grab it.

Twilight used the moment to push the door open further and gain entry. "Yes, soup. Starry made it fresh today." Twilight froze, she saw a sideways moving behind Rarity. "Gel, get in here, now."

Hearing the change in tone from his wife's voice, Gel slipped inside and closed the door behind him. "What's going on?"

Rarity sighed. "You are going to find out, I know both of you too well, you will always find out." She lifted her forepaws up and slipped back the cowl. "So you might as well laugh now."

Both Twilight and Gel blinked at the shaggy head, groomed to perfection, with the softest-looking fur they had ever seen. "You're a diamond dog?" Twilight froze, looking around. "Great joke, where are you, Rarity?"

"It's me, I… there is a sort of curse on them, you see." Rarity cast off the cowl completely, revealing her canine body. She walked into her kitchen and started brewing some tea. "I had… an arrangement, with a diamond dog named Growl." Gel watched as Rarity worked the teapot and kettle with ease, her dexterous paws more than a match for the task. "I found gems for him, he dug them up and we shared them between us."

"Did he do this?" Twilight clopped a hoof sharply on the floor.

"He did, but wait!" Rarity started the leaves steeping. "He couldn't help it." She sighed and leaned against the stove. "This is going to be quite a story."

Gel and Twilight took offered seats and in no time tea and some soft biscuits were served. "So where did this happen?" Twilight was still a little impatient to hear, she cared a lot for her friend.

"Where we usually meet, out in the old quarries north of town." Rarity sat down and sipped her tea. "It was all going normally, although I noticed he had cleaned himself up a lot. He certainly still smelled of dog, but not… not of dirty dog." She hated that her heart still beat a little faster at the thought of Growl, but the effect of what was obviously 'heat' was slowly wearing off as the days went by.

"You did your thing, found the gems?" Gel passed a biscuit to each foal for them to worry at.

"Yes, he had me reveal where to dig for all the gems in the area, in fact. In hindsight, I realize he was tiring out my magic." Rarity couldn't help but reach over and tickle the filly beside her. "She has your horn, Gel."

Twilight snorted. "She has a lot more of him than that. What happened next?"

"That was when he jumped me. He had kept making mentions of how nice I was, of course he was trying to butter me up. Next thing I know he got a collar around my neck and was trying to control me with a leash. With no magic, I had a decision." Rarity sipped more tea and chewed up a biscuit herself, taking her time. "He was certainly energetic, and I can't say it was completely horrible. I passed out toward the end, then woke up as you see me. He took me again… I shouldn't lie, he didn't give me a choice in the matter but I wasn't unwilling at that stage. Then Aloe and Lotus found me. Sweetie sang us both to sleep, but she recognized me." Tears started to flow, and Rarity didn't want to stop them. "She saved me."

Twilight and Gel knew when to keep quiet, their foals didn't. Winged started to cry with Rarity, sobbing while reaching to hug the diamond dog. A flash of orange magic heralded Apple Seed's first teleport as he landed right on the former mare's lap. "Oh!" Rarity stopped her tears a moment, a silly grin coming to her muzzle as she hugged the two foals and kissed each on their heads. "You are both right, it is a silly thing to cry about." Gel looked at his wife, gave a little shrug and got one back in return. "Oh don't give me that, you two brought them for a reason, admit it." Rarity had no anger for the most adorable therapy.

"Gel, pay attention, this is a good lesson for a prince." Twilight cleared her voice and turned to Rarity. "Of course, nopony can resist their charms. I knew from the moment I heard that you were acting strange that this was the cause and that I should bring my foals." She gave a nod of agreement with her own words.

"You are full of it, Twilight Sparkle." Gel kissed the alicorn on the cheek. "And you, Rarity, relax. Nopony will judge you for this."

"There is more." Rarity kept hugging the little colt in her lap, letting the changeling filly snuggle in to her side. "Apparently this change lasts until the pups are raised and, likely, weaned. Although between Sweetie Belle and your little ones, I don't find motherhood quite the terrible thought that I did before." She held back her tears, if only for the foals.

Twilight opened her mouth but stopped when Gel moved forward. The stallion crouched low and reached for one of Rarity's paws. "Rarity, would seeing him… dealt with… would that help?" The stallion left unsaid how he would deal with the dog. "You don't have to tell me to do anything. I will hunt him down, stuff him in a pod for the rest of his life."

"No!" Rarity cut in, then stopped. "Well… he needs to be driven off. I didn't realize… what if he did this to another?" A little hoof patted her cheek and drew the canine's attention down to Winged. She kissed the filly on the head.

"Twi, I might miss the wedding." Gel kissed the paw he had of Rarity's. "A prince does not let his ponies be assaulted." He stood up and turned. "You said north of town? A cave system?"

Rarity nodded, then spoke up. "Yes, the quarry just north and a little east."

Gel kissed Twilight soundly. "Sorry, I need to-"

"You need to do this, don't be sorry." The alicorn grabbed the stallion's jaw with her magic, kissing him again. "Meet me in the Crystal Empire, as soon as you can."

Starry waved farewell to the royal entourage. "Just me again, castle." She rubbed a hoof along the door frame. And me, don't forget me! Starry giggled and reached out within her mind. "I could never forget you, Twinkle."

Pulling the big doors closed, Starry was about to turn when she felt a weight settle on her rump. A look back revealed a blue pegasus stallion. "R-Rainbow?"

"I wanted to return a favor." Dash flapped the wings he was still getting the hang of fully. "So you get a choice, right here, the dining room table, or your bed." Giving a buck of his hips, Rainbow felt himself press against the mare's plot.

"Table!" Twinkle's slight twist to the voice was evident to Dash as the mare laughed and ran out from under him. Eyes narrowing, the stallion started to trot toward the kitchen, where he had seen Starry's tail disappear into.

Starry had to move fast, using her horn, she scattered chairs out of the way while Twinkle ran right up to a table and, folding her forelegs, climbed onto it. As Rainbow Dash came around the corner, he saw the unicorn's plot waving at him, tail arching up high. A shudder ran through his body. "I'm not used to this, I may… lose a little control…"

Looking back over her shoulder, Twinkle giggled. "Please do!" She waved her plot in the air again and both of her saw the stallion's eyes go wide, nose working. "What are you waiting for, an invitation?"

"Rarity didn't say it would feel this intense…" Dash walked forward, feeling himself slide free from the hefty sheath between his legs. Thinking on what he would like, he climbed up, planting both legs apart and to one side of Starry, facing her. "Is this suitable?"

Panting in hunger, both mare and symbiote looked down at the huge member between the pegasus' back legs. "Wow, you are… big." Starry got the words out first, feeling her other self quite lost for words. Without thinking, she leaned across and scooted further up on the table. Leaning in, Starry kissed the tip of the hefty length. Kissing it a second time, Starry felt her tongue push free and lap along the dark blue head, tracing around RD's urethra before her mouth opened and she took the end of him.

Dash groaned, his wings flaring out wide. A few weeks back and he… or she at the time, would never have thought of a pony as sexy, let alone a mare. He lifted a hoof up to press gently at Starry's withers. "That's so good…"

Hearing the encouragement, Starry tried to take as much as she could of the big stallion. Unfortunately he was just too big for her to take more than the tip. Pulling back, she looked up at barrel and then chest. "I want you in me, Dash."

Rainbow had never heard words he wanted to hear so much before. "On your back. I'm old-fashioned." His command was quickly followed and he pressed himself, belly-to-belly with the mare. His shaft was pressed between them, soft fur tickling the sensitive flesh. "Now hold on, and be loud."

Feeling as Rainbow Dash drew his body downwards, Starry didn't need to be told, not when the stallion lined up and bucked the first inch into her. "Oh Celestia!" Her voice caught as he froze above her. She was plugged with heavy stallion cock, but managed to beg. "What… What's wrong?"

Dash shook his head. "Celestia is the principle of the school I went to. It's so odd hearing you call her name like that." Rainbow gave a little hump, the mare under him felt amazingly tight around him.

"C-Celestia was a teacher? I… push again, push harder." Starry looked up at the powerful and sporty stallion above her, when he did just that, shoving nearly half of himself into her, she screamed out, squeezing down on him. "DASH!"

Hearing his own name on a mare's tongue, vocalized in that way, drove the stallion into a frenzy. Rainbow drew his hips back a little and shoved forward, repeating the action, hearing his name each time, until all of him was in.

Neither Starry nor Twinkle could think straight. They were stuffed so full and it was all either could do to shout out their lover's name with each thrust. And each thrust felt like it shoved pleasure into them, their body almost out of control as the huge shape pulled back and shoved home again, over and over.

Rainbow Dash had lost a little control himself, but he did just as he was told he should, let his body go and do its thing. It did it well. As their dance rhythm grew more and more intense, the stallion started to feel an ache, a burning need growing, and it wasn't until his climax rushed onto him that he recognized it for what it was. Bucking hard, he drove himself and a lot of pony seed deep into the mare.

Starry squeezed down tight, each thrust the stallion had done felt like a small orgasm, but now she recognized them for the fakes they were. She was set adrift, rolled under waves of pleasure, with only Twinkle to keep her company, not that her friend was in any better shape.

"Getting started without me?" Rarity's voice came from the doorway, Starry leaned to the side enough to see her friend and gasp. A big white unicorn stallion stood there, looking perfect.

Oh this is going to be fun.
