Three of the does ambled in, pushing the door open as they had observed ponies to do. They smiled as they saw four ponies passed out on the floor. Advancing on them, two chose the horned ones and the last picked the drab-colored hornless and wingless one.

One of the does squirmed down, pressing herself back against the pretty blue-green pony. Horns always gave her problems but she began the effort to pull the pony up and in. Unlike all the others she had encountered, this one had something quite firmly attached and as she got the mare's belly in, she had to use her magic to push and force it off, it certainly wouldn't be needed where she was going.

Another of the deer had selected the white horned one but, when she got close to them, something felt… wrong, not quite usable. She gave a huff and nosed the last unclaimed pony and beamed with delight, much more suitable. Settling down, she relaxed and extended herself. No horn, no wings… so much easier. She gently drew the already comatose pony up and into her, settling the soon-to-be-stallion deep in her womb.

The final of the three deer looked quite upset. There was something quite strange with two of these ponies and they just wouldn't do at all. She wandered out to find her other sister.

"How many of you are staying at the castle?" Twilight leaned in against Gel, memories of their previous night and how tight he had been over her.

"You are smelling good." Gel nibbled at her ear, ignoring the question. He had left a few behind at the Crystal Empire, it was true. He didn't want the nest to run out suddenly or, worse, have another disaster like what happened with the train. "Enough." He felt Twilight's tension ease when she got her answer, he really loved playing with her like that.

"You are insufferable." Twilight kept leaning into the stallion as she opened a book up that Cadance had loaned to her. "But lovable." She gave the stallion a kiss before flipping to the page her bookmark was on.

The ride was a quiet one, Gel had a few of himself along for the ride and deemed it a good idea to leave one in Canterlot when they stopped there. Starry and a very small gooplicate climbed on there. "Oh wow, everypony is heading back?" The unicorn settled into spot by the window on her own, well, not really. The little gooplicate moved up and settled in beside her. "Oh, don't trust Twinkle yet still?"

Gel shook his head. "Opposite, actually. I realize that… well, I took a little care and you know what, all of my gooplicates but this one were incapacitated. If it weren't for you and Twinkle we might have all been lost in that nest."

"Nest?" Starry blinked. A nest… not changelings, he calls that a hive. She kept that just between them and closed her eyes, focusing on her love for the second self, Twinkle. "Something crazy happened, I gather. I am sure I will hear all about it when we get home."

There was a moment where both Starry and Twinkle were focused on the little stallion.

"You want back in?" Starry reached a hoof out to rub Gel's little head. "Almost makes me proud, that you feel safe in me." And Starry was surprised, if feeling a little odd. A few months ago she certainly wouldn't offer this to anypony.

"Thank you, I will take you up on that… uh, mind if we do it now?" Gel had the sense at least to look like he was sorry for asking.

"Such a needy stallion, can't keep you out of mares. What will your mates think?" Starry booped the little gooplicate on the nose and then lay down, her plot aimed away from everypony. Gel walked around her, nuzzling and rubbing his cheek along her as he went until he was right there, right at her vulva. "Oh!"

Gel started to push in, he thinned himself down as much as he could, to make this as easy for the mare as possible. Starry had to bite her tongue as she looked around, most of the other ponies in the car were looking away. She really wished they all would.

The changeling pushed deeper and deeper, having to stretch Starry a little to work in but, when that last barrier was reached, it was held open. Gel couldn't help but smile, he curled up into the dark warm place, beside the parasite still living within the mare.

It was early evening by the time they reached Ponyville, the long trip from the Crystal Empire leaving them all both hungry and tired. It was certainly a consternation, then, when as they were getting off the train, a very red-faced Mayor Mare was standing there. "Princess Twilight!"

The voice confused Twilight at first and her first instinct was to cast the revealing spell she had used on one of Chrysalis' drones at her brother's wedding. The stallion that looked just like Mayor Mare seemed to giggle at the obviously ticklish spell. "Okay, who are you and what have you done with Mayor Mare?" Twilight stomped right up to the stallion.

"Princess, please, I don't know what happened but I woke up and… this!" Having gotten out his message, relief flooded the gender-bent pony and with a silly smile the stallion flopped over and fainted.

"Well, that is certainly different. Maybe a curse?" Gel was up and beside Twilight, reaching a hoof down to poke the stallion before them. Mayor Mare woke suddenly and looked around, he was more than a little confused and the hoped-for reversion to his correct gender hadn't happened.

"It could be a curse, Mayor, please come with us." Twilight began trotting off, not realizing for a moment that a pair of unseen eyes were bright and focused right on her. "I am sure we will have this all fixed up in no time!"

"They grow faster in you, Bold." Luna lay beside the changeling in question, each of them resting their head on the others belly. "I think I like having them in longer, not that… oh…" Luna heaved, laying another big egg into the clump that were already behind her. Twisty was playing catcher. "But maybe I need a little bit without eggs, or with only a few." She panted, a soft green glow in her eyes, planted there already by the queen.

Bold felt another of the eggs shift inside the belly of the alicorn. "Another is coming, would you like to try something else?" She looked down her own body, seeing the dark face of the Princess of the Night gazing back at her. Her own power rose but, unlike Twisty, hers didn't control minds. Bold controlled libidos.

A little more white showed around Luna's eyes and she gave a deep moan. Her body had learned all about laying eggs, but this immense pleasure was something very new. She panted and huffed, straightening up and bearing down. The climax lasted from the time of that contraction's start right until, nearly three minutes later, Luna ejected the egg. Her eyes fluttered shut, her energy almost spent on just that one egg.

"Two to go." Bold's words made the alicorn groan, surely she wouldn't survive both this and Twisty's gentle commands that she 'enjoy her laying'.

"What are you doing to my sister?" Celestia, her own belly flat once more, pushed the door open and stalked in. She saw a green glow pooling around Luna, not just her eyes but her whole body suffused with changeling magic. "Okay, explain this." She couldn't stop the smile at seeing her sister waylaid by both their lovers.

"I just helped her lay them easier, I might have put in a little suggestion that it feels pleasurable instead of uncomfortable." Twisty looked completely innocent, as she always did, but never was.

"And?" Celestia turned to Bold. The lingering cry had caused her to have to put court into recess.

"I haven't used my power on anypony since you captured me, I guess I might have slipped a little too much into her." Bold blushed and leaned in to kiss the dark alicorn who was smiling, despite looking completely worn out. "It should only last an hour!"

"She has two more eggs to lay." Twisty rubbed Luna's thigh, her hoof working up to trace the mare's cutie mark.

"Okay…" Celestia turned to leave, realizing there wasn't much she could actually do. Then it hit her. Stopping and focusing her magic, spreading it out to wrap around the room perfectly, she gave a nod. "And that should last the day. No sounds will leave the room, finish your games with Lulu and then let her sleep."

The changelings didn't hear her hooves once she was outside. Bold quickly looked down. "She was so mad with us!"

"No she wasn't." Twisty sounded confused. "Wait, you could read emotions from the whole city with a bit of effort, what happened?"

"I wouldn't drink from the Princesses! They are your mares!" Bold looked scandalized, caught between defending her honor and rubbing Luna's cheek.

"You are my mare too. Drink from them, when they give you love. Reach for them, they are no fragile fillies." Twisty saw the slight movement in Luna's side and grinned. "If anything I think Celestia tasted of anticipation. I bet you will be asked to-" Her words were cut off as Luna began to call out again, her eyes wide as contraction and climax started at the same time.

Vinyl gave a sigh as she woke up. She tried to look around for her glasses but couldn't find them. Lucky she didn't need them anymore, although she still liked to wear them. "Oh, that toy…" The black rubber thing was right before her nose, but the mare who had been wearing it wasn't. She couldn't stop herself, she tilted her head and stuck her tongue out. The taste of her own musk came back, of Sweetie Drops' and even the sweeter taste of Octavia. "Okay, going wild until we all pass out is fun, but who was last standing?" She sat up and looked around properly. At her side Octavia was groaning and shifting a little. She looked over to the two stallions and smiled. "Wait a second…" The soft, happy music in her head changed to alarmed and it woke Octavia up from her light doze. "Very funny, who is playing a prank on us?"

Octavia watched, bleary eyed as Vinny rocked the flank of the aquamarine pony that had been the cause of all their troubles. Something wasn't right though and she sat up. "Who… who are they Vinny?"

Lyra was first to wake, it helped there was somepony shaking her. "Ugh I'm awake!" She rolled over and felt the silly toy move a little between her legs. "Can somepony please get this toy off me?"

Then it hit the two mares who were most conscious. It really was Lyra. "Dibs." Vinyl grinned and reached a hoof over, rubbing the 'toy' that Lyra had been complaining about. It was warm and very real and started growing larger thanks to the attention. It's owner also sprung up, his eyes wide.

"What the hay…" Lyra watched as Vinyl was hoofing him off. It was mesmerizing. "Don't stop…" Vinyl grinned and started to move when her mate pressed a hoof to her.

"Vinny, stop, something odd has happened and… oh now look, you got Lyra all excited." Octavia shook her head. Sure enough, the pony shaft was now at full mast and shaking off the grip of her mate, Vinyl stepped forward and sat down, pushing back and giggling as the shaft bumped her thigh. "Oh if you are going to ride her, do it right…" Octavia reached a hoof in, guiding the tip to the mare's entrance.

"Thanks Tavi." Vinyl slid down Lyra's newest addition and the stallion's eyes rolled back, his body arching as the mare rode him most perfectly. "Oh a big one… hay Tavi, Sweetie is waking up too, and I think she got stallioned too, we both have a pole to play with!"

Lyra was lost in the emotions and feelings. He had just woken from a dream he couldn't remember and was… well, feeling pretty gosh-darned good now. But this wasn't the right angle. He grunted and his horn lit, lifting Vinyl off his lap and setting her down on all fours. Lyra reared up, memories of the fun they had been having before sleeping filtering through his mind as he mounted the white DJ, shoving himself back into her hot depths.

The world narrowed for the two, Vinyl doing her best to arch her back into each thrust, pushing back and feeling the stallion's thighs grind into her rump. She looked over to see Tavi was similarly bent on getting Sweetie Drops' to mount her and, from how her wife was moaning, she seemed to be doing as well.

His pleasure peaking, Lyra felt the focused pressure, the tingling and finally, he unloaded into the mare under him, face taking on the silly look all stallions get. The soft depths of Vinyl's body clutched and milked at him, making the aquamarine unicorn want to just melt down onto her back. Then something hit the back of his mind, some important detail. "… the fuck is going on?"
