Prompt: "I'm pregnant." - Rodan x King Ghidorah - Kaiju version
(It was weird to have Rodan saying it, but welp, here we go! - Related to "Hatchling - Rodorah".)
Rodan noticed the change before his mate did. It still wasn't fully processed in his body yet, but it was there, like something he couldn't grasp, poking on the back of his mind, again and again.
He was quite surprised by it, though, in retrospect, should he? Their copulation wasn't just for Ghidorah to take Rodan as his mate, it had the most common reason for any type of copulating. Having offspring.
Rodan wasn't really expecting it to work, since they were different species, and with Ghidorah being a fucking alien! Maybe that's why it worked…
That wasn't really the best moment to have an egg on Rodan's opinion. They were both still recovering from battle wounds, and Ghidorah seemed to be too preoccupied with finding the King and defeating him to actually care for a youngling. But Rodan didn't care about it, he would be a parent, and he would be the best parent there was!
His instincts kicked in soon after he felt that small but growing change. He cleaned the volcano and quickly built a nest made of rocks. Whenever Ghidorah wasn't around Rodan would check it, change something here and there, it was never enough for him…
Ghidorah huffed at him and would wrap a wing or a tail around his smaller form to make him stop jumping from here to there, complaining about how "fussy" he was over such little things.
Rodan always found strange how much of Ghidorah was based out of sheer instinct, but still, he seemed so lost and confused by so many natural things. Well, probably natural things on planet Earth…
The alien only seemed to notice much later, at a moment when it was already blatantly obvious to any other titan if they ever happened to pass by Rodan.
They were resting together on the nest Rodan had built so meticulously, body pressed against each other. Rodan chirped low as Ichi pressed against his head, San against his chest, with Ni on his back. They were sniffing, he noticed.
"You smell different…" Ichi eventually mentioned. "Sweeter…" San added with a soft purr, pressing hard against Rodan's neck.
"I know…" The fire titan said simply.
"And why is that?" Ichi asked.
Once again, Ghidorah was an alien in an alien planet – even if he had already visited this place quite a lot of times before getting imprisoned for a thousand years...
The fire titan backed off a little.
"I'm pregnant…" He answered, receiving curious looks from all the three heads. "I'm carrying your egg." He put it simply.
There was silence for a moment.
"You truly are? So it worked?" San was the one to speak up, excitedly.
"I guess it did…" Rodan answered, almost being silences when the left head pressed hard against his beak, surprising him.
"An egg…" Ni said, staring at Rodan with something akin to awe. The fire titan had never seen such a reaction from the right head. "Our offspring…"
"Yeah, basically…" Rodan chirped low, a little bit uncomfortable with that change.
Two giant golden wings opened around him, almost too big for the volcano's opening, and they soon circled the small form of the fire bird, pulling him closer to the bigger one. Rodan accepted the rubs of each of the heads, his body trembling with the soft rumbling that ran down their necks and their chest.
"The child of a king." Ichi purred deeply.
"Of two kings." Rodan threw back, a little annoyed.
A rumble went down each of the head's neck.
"Of course, my 'king of the skies'." Ichi said, softly biting Rodan's neck, right over the same place he had bitten before to mark the fire titan as his mate. Another proof that Rodan belong to them. Rodan simply allowed him to do so.
