Silver Sky circled slowly around, looking at the two mares. "I wouldn't be so bad, and I'm certain both of you would enjoy the attention."
Silver Stars waved a hoof. "P-pass." The lust still tingled powerfully in her, but she kept her rump pointed away from her male half. "I have foals, you should know that. I have friends, and a life. A lot of things I won't get enjoying the incestous life on an alien vessel of all things."
Fast stepped forward suddenly, drawing Sky's eyes. "Going to try for another nip?"
She shook her head. "Sit down." He did so slowly, eyes on her, and she closed the distance, trailing a hoof slowly over his twitching member from base to tip. "I do miss this body a little." Her tail flicked. "I'd be a horrible liar if I didn't admit I wish Silver Stars still had it, instead of her soft female form." She leaned in and flicked her tongue over the precum splattered head, licking it away. "But you're not Silver Stars."
His hooves rested on her head, encouraging her actions. "But you don't seem to mind?"
She nipped into the pole, knowing it would do no real harm to the stallion, then her tongue returned, trailing along the throbbing veins. "We need you to let us go. Start thinking of how we can all walk off this thing, and stop being a selfish asshole."
Sky suddenly shoved her to the ground, and mounted atop her, pinning her to the ground. "You don't get to tell me what to do."
Fast flicked her tail out of the way, and there were no entrances to her back there. "You don't get to rape me. I'm pretty rape-proof for the casual stallion. Now, you get to prove if you're just another bad guy we need to smash, or a lost pony. Which is it going to be?"
Stars trembled softly, wondering what she would do in Fast's position, and feeling pride swell in her for her wife's bravery.
Sky frowned a little and let Fast up. "Fine... If the ship decides I'm not useful, the magic stops flowing, and I die. How do you get around that?"
Stars perked her ears and focused on Sky. She could see the magic and where it flowed into him from the ship. There was so much of it... She couldn't replicate that, but... She slipped herself between them, her magic at least, and began to replace it with a smaller flow as she cut off the ship.
Sky hissed in pain, and began to dwindle. "No! What? Please... I don't want to die." He gazed at Stars with desperate and sad eyes. "Please..."
Stars felt the ship's energy suddenly cut off and she rushed her magic in to fill the hole. Sky was about half their height, and she was certain he wasn't invulnerable anymore, but he wasn't dead. "There."
Sky looked himself over, and looked up at the then towering mares. "What did you do?" He took a slow step back. "Everything feels huge, and... What did you do?"
Fast glanced over at Stars. "I imagine she saved your life, if I had to guess." She reached over and swatted at Sky's still erect stallionhood. "You're a little small for my tastes now."
Sky grimaced and curled a little, protecting his genitals. "That hurt..." Fear suddenly spread over his expression. "That hurt... Is that what pain is like? I... didn't know."
Stars raised a brow. "I thought you had my memories?"
Sky shook his head. "Memory of a pain is nothing compared to feeling it. I don't want to feel that ever again. I'm... I'm so sorry." He sank his head. "I won't hurt either of you ever again."
Fast leaned in and kissed the apologetic alicorn on the forehead. "Aw, that's alright little guy. Now how do we get out of here?"
Sky nodded as he looked over the walls and began a slow circuit. Smaller and weaker, Stars felt less threatened by him and turned more slowly to keep him in view. When he moved to a wall near her, she danced away, only to feel his tongue suddenly flicker just under her tail and she collapsed with paralyzing delight and a groan she thought didn't suit her at all.
Fast scowled at him. "Leave her alone."
Sky shrugged a little. "Just a taste... She liked it." He leaned in and sniffed at her. "Who sowed this field..." He licked over his lips, shaft twitching as if he were considering clambering up on top of the prone female.
"Do it and I'll show you whole new worlds of pain to experience." Fast took a meaningful step forward, which sent Sky back.
"Fine fine! What's the big deal anyway, she can't get pregnant twice." He turned to the wall and tapped at it with a hoof, causing a door to emerge from the formerly featureless wall. "This way." He grabbed the handle in his mouth and gave it a turn, securing the way to freedom into a hallway much like the one they had seen at the entrance.
Stars recovered and sat up. "You really shouldn't do that."
"Oh?"
She scowled at her smaller male counterpart. "Dummy, who's keeping you alive right now?"
Realization slowly came to Sky. "Oh... Am I going to be stuck like this?"
Stars raised a brow. "Hope not. I can't sleep like this. You're going to need to stop being a construct, or find a better source, or I only delayed your passing."
Sky reared up on his hind legs, his forehooves on his chest. "I didn't choose to be a construct!" He fell back to all fours. "You're just angry I have your old body."
Stars nodded quickly. "Actually, yes, that is part of it. Being solicited heavily by myself is really creepy."
Fast peered down the hallway. "As amusing as it is listening to you talk, we really should be trying to find Starlight and Spike, not to mention making this ship go away, forever if possible, or at least not zapping Ponyville."
Sky shook his head. "Oh, it stopped attacking."
Fast raised a brow. "Why?"
Sky shrugged. "I'm not it, but I do know it won't fire while there are ponies aboard, so while you're here, Ponyville isn't being attacked."
Stars found her attention being diverted by the magic she was keeping in one piece. She could feel alien symbols, words of magic she'd never felt before. She knew the unicorn alphabet, and these weren't in it. What did they mean? She gently prodded at them as she walked, only paying some attention to where she was going as she felt around in Sky's alien body, trying to figure it out.
Sky squirmed and hitched as he tried to walk. "Whatever you're doing... Cut it out... It..." He suddenly went stock still and thrust forward, but nothing came of it besides the motion and his loud grunt of pleasure.
Fast glanced between the two. "Stars, what are you doing to the guy?"
Stars blinked back into the present, focusing on Fast. "He's a huge maze of unknown magic. I just wanted a peek at it. The more I see, the more I want to look."
Sky smiled. "And now you want to admire me? Why couldn't you do that before I got shrunk in the wash?"
Fast laughed a little. "I know the feeling. Not usually with new magic, but I know what you're going through. Keep him in one piece and you get to examine him all you want once we're done here." She nudged him with a hoof. "You, on the other hoof, keep us moving so she gets distracted, but not too distracted. She lets go, poof, no more Silver Sky."
Sky shrank a bit at the implied threat. "I'll be good." He turned and trotted ahead of the mares, peeking left and right as they came to intersections. "I may be created, but so were both of you." He turned right and began down a new hallway. "Just because my 'mom' happens to be a huge thing doesn't make me less alive."
Fast shook her head slowly as she followed. "Ponies usually don't vanish the moment you stop thinking about them."
"What about foals?" He glanced over his shoulder. "Ignore one of those awhile, they might vanish." He pressed a hoof on a door and it slid open after a brief pause.
Stars looked around the office they seemed to be stepping into. It looked like a doctor's office, with a bed to lay someone on, medical tools, and everything else. Sky seemed to be headed to the other side where there was another door. "Do you know where you're going, or just guessing?"
Sky looked back at Stars. "I'm going to where the vessel wants me, or I should say us." He turned up his nose. "At least someone wants me."
Stars rolled her eyes. "You're sounding less like me by the moment, and you didn't sound much like me to start."
Fast nudged into Stars' side. "Can you change what he looks like? If he didn't look like your old self, it wouldn't be half as creepy. The little bastard might actually be likable."
Stars followed the shaken-looking Sky through the next door. "I'm not that mean. He'll get his chance to decide where he goes after this is over. To his credit, he... Actually." She scowled a little at Sky. "You weren't trying to be nice or merciful, you just wanted to live."
Sky's ears fell. "Guilty... I'm just barely getting used to being alive. I'd like to hold onto that. I don't think that's wrong."
Fast rolled a hoof. "I suppose not, but you have a lot to learn before you hurt someone without trying to."
Star got a little grin, but said nothing. Fast spotted it and giggled, but didn't pry into it.
A tremble shook beneath their hooves and fire gushed out from ahead of them, rushing through the intersection. As it cleared, Starlight emerged, huffing, but intact, with Spike on her back. Spike pointed at them with a huge smile. "There they are!"
Starlight crouched. "They have one of them with them. I'll take care of it.
Stars moved quickly over Sky. "Easy, Starlight. He's a good guy, or at least not a vio--Eeee!" From his place under her, Sky leaned up and affixed himself to one of her teats, small tongue dancing over the sensitive flesh and making her dance around from hoof to hoof.
Fast snorted amusedly. "Meet Silver Sky, our very own lecherous magical construct." She rolled her eyes back to Starlight. "You two alright?"
Starlight shook herself out lightly, her fur color returning to close to normal. "We've been attacked by devilish little turrets at every corner. Every hallway! There is no end to them and I was wondering if we'd ever find our way out ever again."
Spike tilted his head at Sky. "Why'd you pick him up?"
Silver tried to step free of him, but he walked with her, nursing and licking at her. If it were attention she wanted, it might be quite nice. Instead it made her agitated and increasingly angry. "You've made it clear what I already had in mind." She shoved him with a sudden silver hand, knocking him out from under her. "You'll get your chance."
"I will?!" Sky's tail was wagging excitedly.
Silver smiled, and he didn't like the look of it, and his tail tucked. "What?..."
