This was my first ever collaboration on a story I've done. This story was made by Trek.king and I. We took turns writing paragraphs until we finished it

Story:

Yveltal was relaxing in the grass enjoying the warm day. “Feels nice today. I wonder what i can do.” He said to himself and rubbed his inflatable body. He looked over the area but found nothing so he waited. He looked at the clouds and relaxed; however a glint of light caught his attention. He narrowed his eyes. “What is that?”

The light grew nearer as well as brighter, nearing the surface. Yveltal saw it was nearing his position. He got up and out of the way as the light crashed down into the land near him. He looked out from behind a bush. A large metal like ship was crashed into the ground in front of him. Yveltal tilted his head, “What on Earth is that?”

Suddenly a door opened on the side of the ship. Out from it came a blue blob of slime. Yveltal was curious and walked over. “Hello?”

The blob looked at him. “Hello”, he responded. I need some help. Let me borrow you.” The large goo moved to Yveltal and opened his valve which was in his belly. “I won’t be long.” The goo entered Yveltal’s belly and took control of the Pokémon.

Yveltal stammered, “W-wait…”

The goo replied, “Relax, now all I need you for is to repair my ship.” The now controlled Yveltal started to find metal scraps and screws and started to patch up holes, soon bringing the ship back to one piece. The ship was able to start and the goo released Yveltal from his control, “There we go, I just needed you repair my ship.”

Yveltal was slightly miffed at the goo but sighed and rubbed his belly. “You feel nice in my belly. I want to keep you in for a while. Is there anything else you need me for?” Yveltal sits down and relaxes rubbing his slime filled belly. “Just go ahead and tell me. Though don’t take control over me.”

The slime sighs, “ Well… my home planet… it's dying… and I could use your help.”

Yveltal was a bit taken back by the request, “Oh, uh, well I guess I could help you.

The slime replied happily, “Really!? Thank you so much.”

Yveltal smiled, “No problem.”

The goo replied, “I'm gonna need to quickly take control of your body one last time to get us on course to my home planet. If that's ok with you.”

“Well, I prefer not to be taken over again and all. If there is another way to do it while keeping you in my belly, tell me.” Yveltal stood up and walked onto the ship.

“Well I could tell you how to pilot and all but I have more experience and know this ship better than anyone. Let me control you for a bit. Don’t worry, there is a reward for doing this.” Yveltal let the goo get control.

The goo started talking to himself, “Ok so I need to press this, then I gotta set this then I need to adjust the angle and finally we have lift off.” The ship took off and launched into space. The goo finally said, “Ok, now I just need to activate the Hyper-Drive.” A blue light surrounded the ship as the it took off into Hyper-Space.

The slime released his control, “And done. You are not controlled anymore.”

Yveltal stretched out and sighed a bit. “Feels out gaining back control. Mmmph. Say how long till we get to your home planet?”

The goo replied, “It won't take long, at most a couple hours.”

Yveltal nodded, “Alright, that's not too long, so what should we do?”

The goo replied, “I have zero clue, I never planned to get back home, though I think my calculations were off, we are approaching the planet quickly. I think I put the Hyper-Drive on a bit high up.”

“Oh well that is ok.” The ship approached the slime planet and landed after a few minutes. Yveltal got up and walked on the planet. He heard a voice. “Hello?”

“Ah yes. You must have come to help me.” It was the planet himself.

“Oh my. Well yes I came to help. How do I stop your process of dying?”

The planet chuckled. “I made it up. I am not dying; I wanted to see who would come to help. You did. Hehe. Now for a reward.”

“What kind of reward?” Yveltal tilted his head.

The planet made a small pile of slime open Yveltal’s valve. “You get to have me in your belly for as long as you want.” The slime began to fill up Yveltal. The bird blushed and lay down to enjoy this wonderful feeling. The planet took its time and took a whole day to get in Yveltal’s belly completely. It shut his valve once inside. “There we go.”

Yveltal murred and patted his belly which jiggled in response. “Oh I am going to keep you forever.” The planet wiggled and pleased Yveltal. Yveltal would be planet size from this. “Mmmmmmm.”
