The Band of Loyalty

Rainbow found herself floating in a nebulous void, surrounded by red and purple clouds, with tiny, colourful pinpricks of light poking through the darkness. She spun around, looking all directions, but her worst fear was realized; she was completely alone.

She picked a direction and flew as fast as she could, though the vastness that surrounded her was so expansive that she couldn't tell if she was making any progress. She couldn't feel the wind rushing past her, indicating that there was no movement.

"What have we here?" asked a voice. "Someone come from beyond to visit me?"

Rainbow spun around, looking for the source of the voice. "Who are you?" she asked. "Where are you? Show yourself!"

The voice chuckled. "I haven't been hiding. I am all around you. Do you have a name, little one?"

"Don't act like you don't know who I am. I'm the greatest flier Equestria's ever seen!"

"I know not who or what Equestria is, little one. As you have yet to answer, am I to assume that you have no name?"

Rainbow huffed and folded her arms. "Rainbow Dash. That's my name."

"Rainbow Dash." The voice made a small slurping sound. "What a lovely name."

"Alright, I told you mine. What's yours?"

There was a pause. The clouds shifted around her, coming to form a face among the stars. "You may call me King. That is what all the ponies beneath me refer to me as. Or rather, that is the translation I found when I probed your brain for speech."

Rainbow grasped her head in her hands. "I didn't give you permission to look inside my head! How dare you!?"

"Now, now, Rainbow Dash. It would hardly be beneficial if we couldn't communicate. As they say where I came from," King then recited several sentences in a language long dead. "And I think you'd agree that we don't want that."

Rainbow shook her head. "I refuse to weigh in. I don't know what you said, so I can't agree or disagree."

"My point exactly," chuckled King. "Now then, we've been properly introduced. What say we move on to our business, hm?"

"What business?" asked Rainbow. "I didn't agree to anything."

A black tendril wrapped itself slowly around Rainbow's neck. "Not yet, you haven't, but you see, I'm not dependent on your agreement. Whether I have your blessing to do what I must is entirely optional."

"Let go of me!" Rainbow tried to fight back, but more tendrils came forth to bind her wrists and ankles, locking her in place.

"Now, if you accept my offer, you can benefit greatly from my power. Fortune, fame, glory... Everypony in the world will bow to your whims if you join me. The more you resist, the less you have to gain. Don't you want everyone to love you? Do you want to hear them chanting your name, worshiping the ground you walk on, ready to fulfil your every desire?"

Rainbow stopped struggling, and the bindings around her neck came loose. "You can give this to me?"

"All this and more," chuckled King. The clouds reformed again, this time taking the shape of a pegasus. "All you have to do is say 'yes.'" King held out his hand, and the tendril around Rainbow's wrists fell away.

Rainbow looked at the hand. "What's the catch?"

"No catch," smiled King. " Merely a condition. Everypony around you will grovel at your feet, and they will do so gladly. In return, you help me to regain my strength. That's all there is to it."

"How do I regain your strength?"

"You just have to become famous. I feed on accolades. The more people like you, the stronger I become. Now, I want to be very powerful, so I'm going to make you very famous, whether you want it or not." King extended his hand once more. "That said, nopony has ever turned down this offer. You'd be the first to say no. Now, do we have a deal?"

Rainbow considered the deal. It seemed mutually beneficial. She couldn't come up with a way this could go wrong. "Alright," she said, taking his hand. "It's a deal."

A wide, toothy smile spread across King's face. "Marvelous. Let's equip you with the tools you'll need to find success. You're the first to take my deal without already being properly outfitted."

The tendrils returned, turning Rainbow around and bending her over. She'd have protested, but a new tendril had bound her mouth shut. All she could do was let out muffled screams.

"Now, now. This won't hurt very much, and is absolutely necessary for our goal to reach fruition. You've already agreed; there's no backing out now." He lifted her tail and pulled her legs apart. She wasn't wearing any panties, having gone to sleep without them. she felt his fingers caress her labia, gently dipping inside. "Such a delightful pussy you have, Rainbow Dash. This will be a fun transition for you."

Rainbow let out a shriek as she felt the tip of a penis press against her slit. She tried to shake her head as he pushed deeper inside. It wasn't painful, but she still didn't want it. She squeezed her legs together, trying to push him back out. She wasn't having any luck, and he pushed even further in. When he reached the medial ridge, his shaft changed direction. Rather than continuing into her vagina, it started pushing out of her gut. As she looked down, she could see it pressing through her skin, making its way out. It almost looked like she was growing a cock of her own.

She resisted the urge to cry. She was tougher than this; she just had to push a bit harder to remove him. As she pushed, she felt a pop, followed shortly by another. She looked at the cock again, and she could no longer see her vagina behind it. A pair of heavy, swinging testicles had emerged right behind her recent addition.

"Almost there," groaned King, his hands gripping her hips for one final push. As Rainbow felt the most painful contraction of her life, the balls tightened, and from the dick growing out of her erupted a sticky white fluid that sprayed across her chest. King leaned forward, rubbing the semen into her breasts. "You are now ready to do my bidding. What a lovely set of thralls I expect from you." He threw back his head an let out a laugh. "We're going to be the best of friends."

With a slap to her arse, Rainbow shot upright. She was back in the tent with Daring Do. She was out of breath and sweating profusely. Part of that may have been the excessive heat in the tent, but most of it, she knew was from the nightmare. What an odd dream she'd had.

Resting her hands on her knees, she took a few deep breaths. As she calmed down, she found herself ready to go back to sleep. As she lay back down, her right hand ran up her thigh. However, as she brushed against her crotch, something didn't feel right. It felt almost swollen. She rubbed the area a bit more, and found the growth to be larger and more sensitive than she'd initially thought. As she looked down between her legs, her jaw dropped.

Between her legs, she'd grown a rather prominent erect dark blue cock, and a pair of fluffy blue testicles to match.
