> The heavily pregnant Princess Celestia is trolling her equally gravid younger sister Princess Luna, who is having trouble getting up and complaining about the weight of her belly, so Celestia puts her belly on her sister's to remind her that it could be heavier, though Luna is not amused.

Been working on this for a while, but finally got this done.

This begun initially as one of the thumbnails that was made for [Elsa and Anna](https://www.deviantart.com/a0iisa/art/Elsa-and-Anna-917918923) picture, but I liked this [thumbnail](https://sta.sh/013enz7gj6rd) so much, I still wanted to use it somehow. Originally I planned to just use some random original designs, but then I was aware (or remembered) of Kotobukiya's Bishoujo line of humanized My Little Pony characters that also included Princesses and I knew I had to use these two.
