Twilight was trapped. She struggled, squirming and wriggling, but the tight prison that held her was unbreakable. She tired herself out, panting out, feeling her lungs pumping air through her nostrils hard. "Would my little princess want to be let out?"

The mare trembled, she struggled harder and harder, and in the end Gel felt Twilight grip and fight around him, inside of him. She tasted wonderful. He eased back from her nose and mouth, letting her speak. "Gel… how do you know what makes me… what makes me hot?" She still couldn't see, and Gel could tell that that was extending her post-coital pleasure.

"Twilight, I can taste exactly when something turns you on or off. I can evaluate in a heartbeat if you love something or hate it. And I read your diary." Gel drew back, flowing off the mare completely. As he drew from within Twilight, she gave a happy squeal.

"Not fair, not fair at all… damn you." The princess really wanted to be angry at the changeling but she couldn't help but feel something was a little one-sided with their relationship. She wobbled a touch as she got up, her legs not quite sure of themselves so soon after… after he made one of her most private fantasies come true.

A bath was the first order for the mare. "You are a liquid?" Twilight's mind was shifting gears as she thought on Gel's nature. The stallion entered the bathroom behind her, nodding. "Okay, so why can't you clean me when you are on me? Oh… of course. You are a liquid, but not a solvent."

Gel had no real idea what she was talking about and stepped into the bath. "I'm a what?"

"Well, a naughty changeling is the first description that comes to mind. How much did you read?" Twilight stepped into the bath with him, her still slightly shaky legs welcoming the relative weightlessness of water.

"Enough to find out just how much being trapped like that would turn you on. I can't believe you peaked just from being bound. Such a naughty filly." He was teasing her, Twilight knew it, but it didn't stop her blushing. "Still, I must say it is a better breakfast than yesterday's."

"We have to leave again, today." Twilight took a deep breath, levitating a brush over and working some soap into her fur. "I don't want my friends, or anypony, to be in her clutches any longer than I can help it."

"As my princess wills it." Gel bowed deeply, his body slowly changing to resemble the mare Twilight had seen him as a few times.

"Who is that?" Twilight pointed at him, then regretted it. There was pain on Gel's face that Twilight would do anything in her power to erase. She leaned in and rubbed her cheek against the changeling's. "Sorry, forget I asked."

"Pattern. She lost her name, she had spent so long in a pod that she couldn't even remember her family, her life. She had forgotten so much the pod couldn't force her to think happy thoughts anymore. She was sent to me to play with, to examine." Twilight watched the grief, she kept cleaning herself, but reached one wing out to curl around Gel's withers. "I guess I fell in love right away. She took a little convincing, but it came to her too and I wouldn't leave her. Then…"

"Chrysalis." Twilight said the name, feeling Gel's body seem to tense in a way that reminded her that his form only looked like a pony because he willed it.

"She won't do anything like that ever again, we will stop her." The stallion's voice was his attempt to convince himself, as much as Twilight. "We will."

The train was a small one. They had fit just a single carriage to the locomotive and had it speeding out, express, to Dodge City. Twilight saw Ponyville speed past, she watched the landscape shift from grassy hills to long, golden-grassed plains. The train was slowing before the town however, a lot before. "Something is wrong." Twilight sat up. Beside her, Gel had been reading a book, a book Twilight blushed just thinking of the title.

"Armor up?" Gel placed a slip of paper in the book and closed it. A pony opened the door from the front of the carriage.

"Somethin's not right. Normally get the green signal from Dodge City station to tell me I can coast in… it is flashing red." The engineer, an earth pony of strong build, looked worried.

"This is our stop, I think." Twilight flicked her wings and looked to Gel. "And yeah, time to get ready. Thank you, you should head back to Canterlot as fast as you can." The last was for the train driver, of course.

As Twilight stepped toward the side door of the car, she felt Gel walk into her from behind. The experience was very different from this angle, he forced inside her right away and Twilight was glad the engineer had gone back to his engine, Gel had climbed her back! "What, what are you… oooooo…" Twilight's protest died as he fell down on top of her, wrapping himself around her, inside her, and soon slipping up to form an open-mouthed mask over her face. "Naughty stallion."

"Wanton mare." Gel whispered in her ear and rubbed her shoulders. He really loved climbing onto her, feeling her muscles tense within him until they grew used to the grip again. The tremble as he pushed some of his mass into her. The taste of her as he did all that.

They dropped off the train, Twilight spreading her wings to make the drop more graceful. The city was in view, but something seemed very odd to both of them about it. Giving a wave to the train as it backed into the distance, they soon found out what.

"Deserted?" Twilight looked around, her horn flickering as they teleported to the roof of a building. "This isn't a small town, there were hundreds of ponies living here!"

Gel reached out, trying to probe with that other sense that changelings had. They used it normally to hunt for the tastiest meal, but right now he used it to try and find ANY meal. "All gone. Let's check that building."

Twilight's hoof raised up, pointing at what looked like a diner. Another puff of her magic and they were just inside the door. "This is really spooky…" Twilight stepped in slowly.

"Look at the food." Gel gestured to a table with one of their hooves. "I know what did this. Chrysalis. These ponies got up, left their food untouched, and just left. There is only one changeling with the sort of power needed to affect this many at once."

Twilight nodded and reached her hoof out and felt the plate. "It's cool. This happened a few hours ago, at least."

"I know where we need to go. Let's head for the hive." Gel's voice was a source of strength for Twilight, it made her feel like she wasn't alone in this eerily empty city.

"A few hours," a new voice cut in, responding to Twilight's words, "but do not worry little pony, you will be with your friends soon." As they turned Twilight saw the changeling, their eyes starting to glow. She blinked, able to shrug off the initial effects of the hypnotic magic only because of Gel's eye covering.

"They don't know about me, let's play into this, let them take us to the hive." Gel whispered and blanked out Twilight's vision. Twilight never saw the glow in the eyes brighten.

"Good little filly, step on over here, be a good mare and tell Sneak Attack about all the friends you brought with you." The voice wasn't hypnotic at all, without the flash in her eyes. Twilight felt Gel pour into her mouth as she turned all the way to face the new changeling.

"I had nopony else with me." Twilight's own voice replied, she relaxed herself and let Gel play out the ruse. "I am scared, I want my friends."

"Oh little pony, come with me, I am your best friend." Twilight felt a probing in her head, knew it was the changeling seeking food. Twilight easily focused on how scared she was, foiling their attempts at feeding. "Relax mare, relax and listen to me, focus on me and look into my eyes and relax."

There was the softest whisper in Twilight's ear. "I am fine, relax, think of this morning, think of how good it felt to be trapped and with me. He will expect to be able to feed from you. Do you need help? Nod."

Twilight tried to focus on it, tried to think of being stuck in the dark, wrapped up and at the mercy of a stallion. It worked, she felt a warming between her legs and, eventually, sharpness in her head. The changeling assaulted her mind, biting and drinking from her, the fangs stopping her from being able to change her emotions.

"Me, think of me, Twilight." Gel's words cut through the fog in her head and the alicorn managed to regain her faculties, even feeling the other changeling finish his meal.

"Oh, a tasty little filly indeed. My queen will be delighted at yet another meal for our hive. Come on pony, follow me." Twilight was still in the dark, but she felt something pull around her head and face, pulling up over her ears and tightening behind her head. There was a tug, her head jerked forward. "Come on pony, when I pull your leash you follow, okay?"

Twilight's legs lifted and moved, with the next jerk. Gel was moving them, performing just how the changeling expected them to. "You are doing amazingly, Twilight, please, just relax and we can get to the hive the easy way." Gel returned Twilight's vision then, the princess seeing the leash trailing from whatever was fastened around her head, leading to the changeling.

Gel was quiet most of the trip, but when Twilight needed to hear his voice she just tightened the muscles in her passages, squeezing at him. Which she did when the changeling suddenly called out. "It's me, Sneak!"

"Sneak?" The reply came from an amazingly well-hidden tunnel entrance. Twilight stared at the cave that was uncovered. "Another one? We are eating so well right now it is a whole different hive!"

"She is tasty too, almost like she got off on being fed off of." Sneak Attack gave a tug on the leash. "Got her haltered, should stop her magic, you seen a unicorn with wings before?"

That shocked Twilight, was the thing on her head really blocking her magic?

"Don't test it." Gel somehow knew what she had been thinking and Twilight gave two gentle squeezes at him. "Okay, glad my princess is still thinking straight. Pattern described what it was like, when a changeling fed like that. Let's see how far we get in before we have to get more active."

"Sure haven't, strange. Oh well, let's get her down to the pods." The guard changeling reached out with their magic, snatching the leash from Sneak, much to the nasty little changeling's dislike.

"Hay, she is mine, I get to…" Sneak backed away from the guard, clearly not wanting to fight the other. "Damn guards, thinking they are so good…"

A tug on the leash drew Twilight's attention away from the retreating Sneak and forward. The halls were dark, but oddly, Gel's covering of her eyes somehow made it easier for her to see in the dim light. Down one hall after another, they finally came to a hugely expansive chamber. "Good pony, you just follow along and soon you will be with all your friends. Siphon! You in here?"

"Yeah yeah hold your… oh, what you got there?" A new changeling advanced, its eyes widening as it saw Twilight and Gel.

"Some crazy kind of unicorn, supposed to taste really good."

Twilight felt those teeth coming again and she was scared of them this time. But they never made it into her. Gel was already within her head, she could feel his tender touch, and being there he defended her.

"Give it up, let me have a bite!" The changeling they had just met seemed agitated and turned on the guard. "Come on, don't hog!"

The guard backed away a little, unsure what was going on. "I'm not doing anything, what do you mean?"

Twilight felt the straps around her head grow tight as the two changelings' argument came to a fight. She realized after a moment, the straps were not getting tighter, her head was swelling. When the first strap tore Twilight grinned, bracing herself and getting ready to 'bring the rainbow'. Another strap, then another. As the last one broke and the halter fell to the ground before her, the two changelings seemed to remember they had a new meal with them.

"How'd it get the halter off?" One reached down with its magic to get the leather contraption.

Now that it was off Twilight felt the release of pressure. It really had been doing something to her magic. "Cast, dispatch these foes, my princess." The words of Gel were flowery and Twilight giggled as she lowered her head and blasted. The beam of bright purple and white light burned through the air and slammed into the pair and slammed them against the wall, where they collapsed. "Ah, glorious destruction at my merest command."

Twilight blushed, now he was teasing her, but she knew that he knew that she liked that. Then she remembered he was linked mentally at the moment, and knew that he could taste how much she liked it. The knowledge, however silly it was to come up with, only made the situation more delicious.

"Hurry now, this is a lot of ponies in pods, much as I would love to get them out, if they stampede the changelings will not be gentle rounding them up. Let's go finish this." Gel moved her legs, but much as Twilight wanted to find Rainbow, Fluttershy, and Applejack, as much as she needed to free everypony, Gel was right.
