Spike shoved at the alicorn trying to displace him and mount Silver mid-air. "Back off, man. This is my ride!"
The doppelganger frowned at Spike. "If I didn't need Twilight to not hate me, I'd throw you to the ground. Do me the favor of shutting your mouth."
Silver kicked and thrashed, but her hooves were in the wrong place to connect with him. Conjuring her mental hands, she grabbed at him, trying to peel him free, but he shook off the mental grips easily. "Did you forget so quickly? It's our magic. Your struggling's just turning me on."
Fast came swooping in from above in the form of a griffon, her talons outstretched. "That's my mare, not yours!"
The moment of distraction was enough for Silver to blink several feet forward with Spike and spin around to face him. Fast collided with the stallion and they began wrestling for dominance, though she had the advantage of claws and talons to scrape at pony flesh. "Maybe if you weren't such an amazing butt, I'd find you hot."
Silver glanced over her shoulder at Spike. "You alright, little buddy?"
Spike saluted quickly. "We should help Fast. Considering he's, well, you, he's not going to be easy."
"Roger that." Silver propelled herself back at her male half, teeth bared. "I don't even know if this will work on a ghost or whatever he is." She went for a bite, only to find herself bitten instead. Her clone grabbed her and held her tight as his teeth worked into her and she felt her senses overwhelmed. Suddenly allowing this strange stallion to have his way didn't seem so awful. She had a burning itch that was turning into a body-wide flame, and the stallion was the only cure for it.
Her clone jetted away, back towards the ship, carrying the furiously attacking Fast and the clinging desperately Spike for the ride until he landed on a small platform and threw Silver and Spike to the ground. "You can present now."
Dizzy with forced lust, Silver staggered to her hooves, her tail twitching. She wanted to submit, but she didn't want to. The two urges warred as she whimpered. "What... are you?"
The doppelganger tilted his head. "I'm you, a better you." He moved around her, bleeding from countless wounds, but not troubled by them despite Fast's efforts. "You can have this. You just have to give up."
Fast struck below the belt. Curling around the stallion, she sank her beak into the firm shaft she found, attacking the source of his potential rape. The clone paused, shuddering. "I need that." He brought down a hoof on her head, knocking her free. "If I didn't love you, I would kill you." He put a hoof on her throat. "Apologize."
The clone was suddenly encased in crystal as Starlight flew in and landed on the platform with the others. "Ha, none of them have experienced that before." She raised a brow at the frozen, and stiff, Silver clone. "Well, somepony's glad to see me."
Spike clapped his claws excitedly. "I've never been so glad to see that spell before. Um, you may want to get rid of him before he figures out how to get out of it."
Silver nodded, quivering with concentration. "Please..."
Fast rolled up to her paws with a snort and gave the clone a powerful shove, knocking him out into the sky to plummet towards the ground below. "Right. Good job, Starlight." She became a unicorn with feathery wings. "Let's get inside."
They turned as one for the small access archway built into the surface of the craft. Spike stepped over to the edge of the doorway and peered inside. "Looks clear, just a hallway."
Silver sighed at that. "It looked that way last time too, but expect it to get violently angry at us." She tapped her chin. "This would be a lot easier if Night or Twilight was here. The ship knows them. It knew the old me, and in no good way. I hope I don't show up as a bad thing, besides intruding with the rest of you."
Starlight strode in. "Then we'll just have to keep our eyes open and magic at the ready." She glanced down at Spike. "That means your fire, in your case."
"Got it!"
Fast nudged against Silver. "You alright? You look worked up beyond anything I think I ever saw out of you."
"Nothing, just this thing fucking me--I mean fucking with me."
Fast raised a brow. "Are you going to be alright? This isn't really the time or place for that, and that's me talking."
Silver shook herself out with a snort, trying to will away the unwanted desires. "He bit me and pumped in all the lust he had. Whatever he is, he has plenty to share." She stepped past Fast with a stiff gait. "Let's get moving before he comes back." Her world trembled as wet warmth ran over her nethers. She collapsed in place and Fast pulled her back, nuzzling into her oversensitive vulva.
"Sit down a moment. We'll work it out of you." She thrust her tongue into Silver, drawing a cry from her as she began to explore her.
Starlight came out and cocked a brow at the scene even as she put a hoof over Spike's eyes and drew him along with her back into the vessel, away from the debauchery.
Silver pawed at the ground, wriggling and moaning wantonly at every touch of her partner's talented tongue against and within her needy passage. Her vulva winked against Fast as she pushed back. It was better than she could remember intimacy being before, perhaps being so high on the pure need for it. "Deeper..."
Suddenly both stopped. They didn't hear the rush of wind, or feel the chill anymore. They were in a small room with no doors. Fast slowly withdrew her tongue. "What?"
Before Silver could rise to her own hooves, the air shimmered, forming the shape of Silver as a stallion. "I made a very serious mistake. I should apologize to both of you lovely mares."
Silver scowled at the phantom of her past. "What mistake would that be?"
The clone rolled a hoof. "You two are a pair. I can't have one, without the other." His eyes went half-lidded. "Ladies, come. It's time to consummate your new place in life." He approached them, shaft swaying under his powerful body. He didn't seem transparent and ghostlike as he had before, instead all too real.
Fast put a hoof against Silver's belly, holding her back. "We don't need two Silver Stars. This one's fine enough for me. Sorry, pal."
He recoiled lightly. "Oh? Very well then. Silver Stars can be her name... I am Silver Sky." He flicked his tail as he closed the small distance remaining. "Now let me show you just how much you excite me. Fast Change, I know you like this kind of game."
Fast frowned as she pulled Silver back further. "Stop threatening her."
"I'm speaking to you, Fast. Let's see that pretty tail of yours."
Fast moved to stand, and Silver stood beside her, both glaring at the stallion they were trapped with.
His eyes suddenly narrowed and he stared at Silver. "My dear mare, someone got to you first. Who?" He sniffed at her gently. "I don't recognize their scent, but their blood is in yours, and a foal awaits. Why didn't you tell me." He raised a hoof to his chest. "I'm not a barbarian."
Silver snorted out a laugh at that. "This is the same guy that tried to rape me in the air."
"As if you didn't want it, on some level." He smiled. "But you're already expecting. There's no point planting in a field that's already been sown. Shame too, plowing's the most enjoyable part." His shaft jumped, spurting fluids to the ground. "I might make an exception, if you like..."
Fast bore her teeth, sharper than a unicorn's teeth aught to be. "I could put some new marks on you if you want."
"Oh, feisty." He flashed his fangs back at her. "Stop playing coy and let me at that sweet red flank of yours." He circled around her, but she kept turning to keep him in front. "Or do you prefer a little foreplay to get the motor running, hmm?"
Silver clopped a hoof on the metal floor. "Where is Starlight, and Spike?"
Silver Sky shrugged. "None of my concern. The others are dealing with them, I'm sure. I don't want to hurt either of you, however. I want you to join me." He turned towards Silver Stars. "Come, my dear mare. We know each other, I will love you dearly, and keep you happy."
Fast lunged forward when Silver Sky turned away and bit into his exposed jewels, but it was like trying to bite through hardened metal, and her teeth felt sore for the effort.
Silver Sky moaned as if it were the sweetest pleasure. "Ah, yes, you can put your lips on me whenever you want, Fast my love. Ah, yes, your womb is still virgin and untouched. May I be the first?" He turned back to her. He was exposed to Silver Stars, but biting him felt pointless, and she struggled to think of a clever spell to buy them time or freedom.
Fast's tail folded in tight behind her, barring view and access of her genitals. "Fuck off and die."
"Such language!"
She leaned forward a little. "I learned from the best."
Silver Sky laughed at that. "I love you more than ever. Stop denying me and accept my love." He leaned forward and pressed his nose to her cheek. "What will it take to convince you?"
Fast put up a hoof. "First, talk to me, instead of attacking me. Rape isn't sexy." She glared at him. To Silver's begrudging credit, he didn't try to push towards her. "Alright... Second, what are you? Are you just some... thing made by this ship to take us down?"
"Yes."
Fast staggered a little. "That's not something to be taken lightly!"
Silver Stars snorted softly. "You're as bad as I am. Why are you defying your orders?"
Silver Sky stepped from hoof to hoof. "Didn't I say? I want to fuck you both, not kill you. I want to be the father of your foals, and to be your stallion... I love you."
Silver Stars shook her head. "You're in love with the idea of being our stallion."
Fast nodded at Silver Stars quickly. "You don't even know yourself." She sat slowly. "You don't know us."
Silver Sky sat with Fast, looking across at her. "If I kill you, then there is no more point to me, and I will be gone. I don't want to die. Do you want to die?"
Silver Stars shook her head. "Of course not... I thought you were a construct, that you didn't even think about that."
Fast tilted her head. "Alright... okay, we're getting somewhere." She smiled a little. "What if you just let us go?"
"Then I would be useless, and I would die." He tilted his head. "On the other hoof, if you became my wives, I would always be useful, keeping you from causing harm as your stallion, forever. Would that be so bad?" He turned his eyes on Silver Stars. "I know how you want to be treated, and I want to do it."
