Hivemind Control

Twilight stood up slowly. The wiggleworm was now properly situated inside of her, meaning that she could no longer feel it. Even pressing her hoof against her abdomen, she couldn't feel anything there. It was as if it had disappeared entirely. She turned around to look at Cercus, and as her eyes fell on him, her vision began to blur at the periphery while her focus on him became much sharper.

He looked different, somehow. His jaw was wider, he was taller, and his chest had taken on the shape of two barrel lids. She couldn't believe how good he looked. He walked over to the box he'd brought in. She enjoyed watching him walk. As he pulled out a bottle, she gladly accepted it and took a drink. How could she say no to him?

The moment the bottle was empty, everything shifted back to the way it had been before the worm had worked its way in. Cercus was the same as he'd always been, but her perception of him had changed. For a moment, she'd wanted to do whatever he asked, within reason, of course. But would she have been able to discern what was and was not reasonable? At any rate, she now understood why the other princesses had changed their minds so suddenly. If she hadn't drank from that bottle, she'd have shared their fate. The one she was needing to take was a different path.

Cercus sat down in his chair and beckoned her over to him. She immediately put up a resistance, as she still needed a moment to collect her thoughts. He beckoned again, and this time, she felt a slight twinge in her muscles, almost commanding her legs to approach. Now was not the time to test how far she could flex away from the rules, so she walked over and sat down in front of him.

"Now, there are a few rules to that potion I gave you," explained Cercus. "It will neutralize the neurotoxin that eats away at your memories, but it also strengthens the one that attacks your decision-making and motor function. We need to tweak that, or the end result will be that you are capable of thought, but unable to resist any command. Not just from changelings, either. If left as it is, you will have to perform any task you can understand. To interrupt that, you need to take in my excretions shortly after or shortly before drinking that potion. Within an hour, to be exact. During that time, you will be highly susceptible to that biological reencoding, so during that time, you're not allowed to take in the excretions of any other changeling or pony. If you break this rule, then you will find yourself unable to resist their commands, either. In this way, Chrysalis could control you if you eat her out within an hour of taking the potion. Do I make myself clear?"

Twilight nodded. The fewer in number changelings she had controlling her, the more freedom she would be able to experience. Two hours of monoamory per day was an agreeable rule to follow, especially if she wasn't planning to have any sex that day, regardless.

Cercus reached down between his legs and extended his cock. Twilight didn't need a command to know what to do with it. She had to swallow whatever came out of the tip. She had another fifty-five minutes to draw something out of it and into her. Whether his load went up her arse, into her pussy, or down her throat was entirely her decision.

It was perhaps best to start with the easy solution. She'd drank the potion, and she'd never had much issue drinking other fluids, and she'd also already tasted changeling cock by way of Mandible. It was something she was already prepared to do.

She narrowly opened her mouth and stuck out her tongue near the base. He was only partially exposed, not fully extended and definitely not hard. She began to lick him gently, noting a much cleaner taste than she remembered from Mandible. His cock was just the same as his balls had been when she'd been made to lick those, and that made sense. Both times, he'd washed recently, though it was less recently this time, leaving a slightly saltier flavour.

Before long, he was at full extension. As her lips wrapped around his glowing tip, his hoof brushed her mane back around her ear and rubbed her cheek encouragingly, guiding her head as she bobbed up and down his shaft. She wasn't exclusively trying to pleasure him, more akin to drawing out the climax as fast as possible. That did mean pleasuring him, but only as a means to her end.

She took in as much as she could, deepthroating him as best she was able. The more contact she had to his junk, the faster he would cum for her, and the faster she could remove him from her mouth. Not that he tasted that bad. He was not too dissimilar to Shining, once the thin layer of skin oil had been washed away by her saliva. If she closed her eyes, perhaps she could even imagine that it was her brother coaxing her to continue.

As she imagined herself back in Canterlot, on those cold nights where she would steal away under Shining's comforter, memories of better times came flooding back. She slipped a hoof between her legs and began to rub, moaning softly as she swallowed the phantom dick of her dear brother. Their parents would be away all night, meaning she just had to wake him up and have him warm her up in his loving embrace.

So wrapped up in the memory was she that when Cercus fired his seed down her throat, she buried his cock deep as it could go, then slowly pulled away, slurping up any and all traces of fluid and drying him completely before opening her eyes and remembering who she was with.

"Very good, Twilight," smiled Cercus. "By how sticky your hoof sounds, I'd say you enjoyed that, too. Which is good, because you'll need to do something similar every single day for the next several months. I'm glad to know that you found it so agreeable."
