Xela the Raptor was swimming with her dolphin friend, Nelly, in the ocean, she was trying to see how far down she could swim in one deep breath. Even though she could hold her breath for a long time, she swam too deep and is now running out of air. Xela has enough air for about 5 mins but she will use more up if she tries to swim to the surface. Then Nelly had an idea, she would swallow Xela whole and give her a lift back to land. She has more than enough air in her body to share with Xela. Not feeling to happy about it, Xela agrees and lets her friend start to devour her whole. Starting head first, she quickly but carefully began to swallow Xela. Nelly has a special ability that allows her to stretch her bottom jaw extremely wide, and her stomach can stretch to the size of her body, or even bigger (a bit like a black swallower). Once she had devoured past Xela's butt, she let Xela get into a comfortable position before slurping down her tail like a noodle.
Once Xela was completely swallow, the dolphin started to pumped air directly into her stomach to help Xela breath and then she would proceed to the surface to release her raptor friend back on land.

Update: I've changed some of the panels with more detailed pictures, also added a bit more to the story.
