It had been a solid month since Chrysalis had joined Aero’s herd, and the Changelings had started hatching soon after the move to the crystal empire as well. During that time, Ceestia had agreed to a merging of kingdoms, creating the Equestrian-Changeling Treaty.

That morning, Aero was enjoying breakfast with his mares as they chatted about the days plans. They were interrupted from their meal as the doors to the great hall burst open. A crystal guard carrying a scroll came running in.

“I apologize for intruding your Highnesses, but we’ve received an urgent message from Princess Twilight.” He relayed, holding the message aloft. Cadence snatched it and opened it. As she scanned its contents, her eyes widened and a sly grin appeared on her face.

“It seems Twily has entered her heat season, and is requesting our dear Aero’s assistance with it.” She explained, passing the scroll to her herd-mates. At this, Aero raised his eyebrows. He knew it would come around, but it was happening sooner than he expected. As his mares each read the scroll, they smiled, knowing that another would soon be joining them.

The rest of the day was spent helping Aero pack a few new belongings before he was set up with a train ticket and sent on his way. Once he had left, the rest of his herd made their way back into the castle and were heading into a large lounge room. What greeted them made their jaws drop.

* * *

Aero made his way through town and waited at the station for his train. It would be arriving in roughly ten minutes, so he took a seat on one of the benches and waited as he watched the crystal ponies and equestrians mill about. It still surprised him just how shiny crystal ponies could be, and part of him silently wondered what it would be like to be one of them.

As he wandered the cavernous world that was his thoughts, a loud whistle in the distance brought his attention to the forefront. Looking off to the left, he watched as the train made its oncoming presence known, its clouds of steam streaming from its smokestack.

Aero stood and joined many others at the platform as the train screeched into the station, slowly coming to a stop before the doors opened and the conductor hopped out.

“All aboard for Ponyville! With connecting stop in Appleoosa!” He yelled.

After that everypony started bustling into the cars to take their seats, or to store belongings for the trip. Aero filed in as well and moved as far back as he could. He opened the door to his compartment and stored his belongings away before taking his seat. As he waited, he pulled out one of the books Cadence had given him. One on foal rearing. She had explained that the info would be helpful when his foals were born.

Soon, an attendant came by and punched his ticket, she closed his door and moved on to the rest of the passengers as he settled in with his book. It would be a while before they hit Appleoosa, so he figured it would pass enough time.

This did not pass the time, more-so it made him fall asleep. And he was jostled awake by the rattling as the train pulled into Appleoosa station. As he sat up, he wiped the sleep from his eyes and the drool from his cheek and looked out the window. All he could see was a wide expanse of desert, with a few bits of brush dotting the landscape.

He left his compartment and headed for the bathroom at the back train car. He watched on his way as many passengers disembarked to continue their travels. He wouldn't be leaving the train after all, so as much fun as Appleoosa would be, he stayed, and returned to his compartment after he had finished relieving himself.

After another, shorter nap, Aero awoke to the train pulling in to Ponyville station. As it came to a halt, he gathered his things and exited out the side door of his car. Once he had his bearings, he made his way to Twilight’s Castle, which he could see glittering from above the town. Numerous ponies waved to him or greeted him on his way, most having met him when he was last here.

After a semi-short walk and a quick snack at Sugarcube Corner, Aero entered the Castle and made his way to his old room. After he placed his things down, he left and began looking around for anypony. Eventually he found the kitchen, and found Spike mixing up something in a bowl.

“Hey Spike. Where’s...um...where’s Twilight?” He asked.

“Yikes!” Spike yelled, before turning around. “You scared me!”

“Oh! Sorry. I didn't mean to.” He apologized, rubbing the back of his head as he did.

“Its ok. I was just startled. If your looking for Twilight, she locked herself in her room upstairs. I bring her food and she usually teleports it in. So I don't know how you’re going to get inside.” Spike explained as he turned back around and continued his mixing. Aero nodded and made his way up to the main Royal Suite.

Once he reached her door, he saw what Spike meant. Her door was currently encased in her signature purple glow. She had magically locked it. Aero sighed and raised his hoof, giving the door a few firm knocks.

“Im not hungry Spike.” Twilight’s muffled voice replied from inside.

“Um actually, its me Aero.” He said, raising his voice a bit so she could hear him. After a few seconds there was a bright purple flash, and suddenly he was standing front of her bed. Twilight was looking down at him from atop her purple felt blankets. Her eye’s had bags under them and her mane was completely disheveled. Her fur had become slightly matted in some spots, whether from sweat or something else, Aero couldn’t tell.

“You came.” She said as she smiled, levitating him up onto the bed as she grabbed him in a hug. “I knew you would. But im glad your here.”

Aero smiled as he hugged her back. As he took in a breath, her scent filled his nose. She was in full heat, and the pheromones she was putting put immediately set off signals in his brain. His wings snapped open as he looked up at this mare who suddenly seemed more beautiful than ever.

Twilight giggled at his display as she brought her lips to his in a deep and passionate kiss. He could feel her inexperience compared to the others in his herd, but the desire he felt from kissing her was more than enough to drive him further. As they kissed, Twilight leaned back, pulling him with her so that he was laying atop her chest. Aero knew exactly what to do as he broke their kiss and made his way down her body.

Every so often he’d leave a kiss or a nip, causing her to gasp and squirm as he painted a trail down her barrel. Finally he reached the promised land, and delved in with fervor as her taste graced his tongue. She tasted like lavender. He caressed her folds with his tongue as he lapped at the juices that overflowed from her marehood.

Every time her clit winked out, he pulled it into his mouth, brushing it with his tongue before releasing it. This caused Twilight to let out loud moans as her body was ravaged by quick bursts of pleasure. She placed her hooves on his head as he began flitting his tongue in and out of her dripping hole.

He kept this up until he felt her body shudder and clamp down on his tongue. Twilight let out a long drawn out moan as she looked down to the colt that would soon breed her. At this point it was all she could think about. It was all she wanted. She slid up and turned over, raising her flank in the air as her tail flagged high.

Aero fluttered his wings as he lined his now throbbing colthood with her moistened slit. He placed the tip against it, gasping at the heat as he slid inside. They both pet out moans as Twilight felt him hilt his throbbing meat inside her. It was the most incredible feeling she had ever felt, and she wanted more. She got that wish as Aero slid back and slammed forward, causing a loud slap to echo the room as Twilight gasped out a moan.

Aero repeated this, speeding up his tempo as Twilight succumbed to the pleasure that assaulted her mind. He gripped his hooves into the soft flesh of Twilights flanks, massaging her cutie marks as he speared her from behind. If there was one thing he loved nowadays, it was a thicc flank. As his wings began to get tired, he grabbed her tail with his mouth and held tightly as its tension kept him slamming back into her, giving his wings a much needed break.

Twilight let out deeper throatier moans as he tugged on her tail. The slight pain added a new pleasure to her that she hadn’t thought of. It was an ecstasy like no other as Aero released his warm seed into her scorching snatch. At the same time, Twilight screamed as her orgasm took over her body, leaving her slumped over in pleasure. Aero slumped over next to her as they cuddle in the warm afterglow. Twilight sighed in relief as she felt the urges of her heat abate. With that she cast a quick spell on her womb, grinning as she drifted into sleep. By morning she would know if his seed had taken.

Back in the Crystal Empire, before everyone had woken up for their day.

Celestia silently made her way into the Changelings hatching chamber, where slept most if not all of Chrysalis’s Brood. Quietly she made her way to the mound of sleeping Changelings and as quietly as possible, woke them. They groaned as they rubbed their eyes, looking around for what disturbed their slumber.

“Shhhhh, I need your help.” Celestia whispered. The Changelings all looked curiously at her as they all followed her out and into one of the Crystal Lounges.

“So, now that I have you all here, I have a request to make.” She explained as they all looked at each other before looking at her and nodding. “Id like for you all to become Aero, and Id like you all to mount me.”

Everything went silent as the Changelings stared at her in disbelief. After a minute or so, one of them was enveloped in Green flames as it was replaced with what was now Aero. Soon the rest followed suit, and before Celestia now stood five Aero’s.

She grinned and brought the first one into a kiss as she laid down on her side. As the others watched, she opened her hind legs, revealing her wet marehood and a winking clit. They all could feel an immense amount of love coming off her that was directed towards their current form. She was completely head over hooves in love with Aero. One of them took the chance and immediately went to work on her clit as it winked in and out. She moaned into her lovers kiss as she moved down and took his now throbbing colthood into her mouth. One of the Changelings that was watching took it on himself to lube up his own member with his saliva before he moved past he brother and slid into the Princess’s tight backside. He groaned at the pleasure as his brother joined him and slide into her waiting marehood. The other two were now on the floor next to Celestia as their members were enveloped in the golden glow of her magic.

As they continued their fun into the hours of the morning, they failed to notice the door opening and the shocked faces of Aero’s Herd as they beheld the spectacle before them.
