Which vore should I write first?

[CasualObserver]

Hey all, longtime lurker and first time poster here. I've figured I'd try my hand at doing something vore-related, so I'm writing a story featuring the two women featured in the attachments (both are from a card game I play). The story involves Luna (the top woman) offering herself to Mercurius (the bottom woman) as a means of boosting her power, with some semi-fatal involved (Luna resurrects at the end of the story). The only problem is, I'm not sure which type of vore to write, so I'm leaving it to a vote. I have an idea on how to write each, so it doesn't matter which wins.

I thank everyone who votes in advance, I hope to have the story out in due time.
