"Are you sure?"

"Of course."

Optimus couldn't believe what he was hearing. James and Luna were both able to be turned Cybertronian. Because of the nanites from Optimus and the spark energies from both the Prime and Stardust, James' body was slowly changing. Ratchet had confirmed there was traces of energon in his blood as well as Luna's.

"This is exciting," said Optimus. "James will be with us longer."

"Indeed," said Ratchet. "I thought I would tell you first. I wanted to make sure my findings were correct first."

"I will inform my mates," said Optimus. "Thank you so much for telling me sire."

"Of course," said Ratchet with a small laugh. "Go tell them."

Optimus nodded and left the medibay fast. He went to his berthroom where his mates were waiting for him.

"Hello love," Stardust said. "What did Ratchet have to say?"

"James and Luna are slowly turning Cybertronian," said Optimus, turning his attention to James. "You'll be with us for a long time."

"That's always good. I wouldn't want to leave you two anyways," said James. "You're stuck with me."

"We wouldn't have it any other way," Optimus purred.

"I love when you purr," James said.

Optimus growled a bit at that with possessiveness. Both he and Stardust activated their holoforms. Optimus gave Stardust a knowing look, the two planning to get James good tonight.

"You belong to us," Optimus said, kissing James with a deep passion.

James looked at the two holoforms curled up around him. He had turned the tables on both of them, sending them into mind blowing overloads until they fell into stasis. He truly did love them both so much. He felt so lucky to have them as mates.

The thought of being like them, being a Cybertronian, sounded pleasing. Being human, his lifespan was shorter than that of a Cybertronian. Yet being like them, he would be with them longer. And that was something he wanted, to be with the two 'bots he loves so much forever. And Gem would be happy to know that James would be with them longer.

And to make it better, his best friend would be one too. With Luna being bonded to Ratchet, her body had started to change as well. It was truly a blessing that they had this chance to change. And they would still help out NEST.

James yawned, feeling tired. He settled down more, going to sleep with his mates next to him.

~~~a few years later

"They should be onlining soon," said Ratchet.

Two bots laid on two berths. The mech was blue and black. The femme was a sapphire blue with neon green highlights. The transformation was a success. The CMO was picking up strong vitals and sparkbeats from the two.

Two pairs of blue-green optics onlined. The mech sat up first, feeling out his new body. Optimus, Stardust, and Gem were at his side. The femme got up off the berth, getting used to the new body.

"You look stunning, my dear," Ratchet purred, holding Luna so she didn't fall.

"And now I can have more fun with you," said Luna.

"I can say the same thing," James commented with a sexy grin. "You two will have your worlds rocked now."

"Is that a challenge?" Optimus asked with a raised optic ridge.

"Go to the berth and you'll find out," James suggested.

"Later, when there isn't young minds around," said Stardust.

"Carrier, I'm old enough. I know what you mean," said Gem. "Besides, it's not like it is anything new to me. Grandsire has done a great job in explaining interfacing to me."

"That's because you need a good education," said Ratchet. "You're of age now for your interface protocols to be active."

"No interfacing for you, young femme," said Optimus.

"What if I bond?" asked Gem.

"We'll see. But you are too young to be dating," said James.

"But I already am," Gem said before covering her mouth with her slipup.

"What?" both sires asked.

"Uh, nothing," Gem quickly said.

"Who is it?" Stardust asked.

"Soundwave," Gem muttered.

The young femme looked at her creators. They hadn't reacted like this when they found out Bumblebee was courting Barricade and bonded to him. It could be that she was younger than her older brother. She feared for Soundwave now, hoping her creators didn't kill him.

"Don't hurt him. I swear we won't do anything until we're bonded," said Gem quickly.

"You better not," said Optimus. His and James' sire instincts had kicked in.

"Uh... look at the time. I need to go... uh... find Uncle Megatron," said Gem, taking her leave.

"At least Soundwave is a good mech," Luna piped up.

"I agree," said Ratchet. "They grow up so fast."

"You'll be saying that when you have more offspring," said Luna. "Though I agree. Young ones do grow up fast."

"Indeed they do," said Ratchet. He leaned forward more and kissed the back of her neck. "Why don't I go take you to our room so that I can show you the wonders of your new body?"

"That sounds like a good suggestion," said Luna.

"We will do the same," said Optimus.

~~~000

"You really were holding back. Both of you," James panted.

"So were you. I never knew how kinky you could be," Stardust grinned.

"That's not even all your body can do," said Optimus.

"Oh? Then you better show me," James said, leaning forward and kissing the Prime before doing the same to Stardust. "I love you two so much."

"We love you too," said Optimus.

"I agree," said Stardust. "Ours forever."
