Or Rarilamia, but I’m not sure if it flows well.
 
Here was a little request done on 4chan. I was just intending for it to be a quick sketch, so the lines aren’t near solid. Despite that, it got a touch-up (by you know who)!
 
The request wanted an entranced Twilight at the princess-occupied tail of Rarinaga, basically. This scene showed up. I imagined Celestia being swallowed down first as Luna’s squirming her way deeper, but there’s nothing there to imply that since I rushed this. I guess the preys are for your imagination! I’ll still tag them since that was what they were intended to be.
