You ever watched a transformers show? Ok so in some movies and show the centre of the Earth is actually the eternally living body of the manifestation of destruction named Unicron.
What if there was a universe where the centre of Earth was an ancient timeless deity, but this deity isn’t of destruction, she’s of pregnancy. A permanently pregnant eternal being at the centre of our world, and Earthquakes are her babies kicking and volcano eruptions are her godly breast milk (lava) leaking to the surface.
I say all this because I have a request of a scientist (maybe also pregnant) communicating with this primordial Goddess, and this Goddess is just super teasing to her for her size. Goddess like “I may be the world, but you look like you’re a Solar system”
The Goddess has the scientist rub and massage both of their bellies, communicating with the scientist to jiggle her own belly and squish it against the Goddess’s, but then to worship the incomprehensible Goddess’s billions of years old belly
Sorry if this is too niche or complicated you don’t have to do it
Tweaked the content of this one a tad to make it a little more about this weird Sapphic love affair between the scientist listener and the deific speaker, but I hope this still hits what you were going for!
(THIS IS AN AUDIO REQUEST)
You're a scientist with a geology firm who has found herself in quite the predicament... heavily pregnant and in some kind of romantic relationship with a deity that seems to embody Earth itself. It's weird, but sweet, so you feign studies and haul equipment out to private areas in the middle of the night just to spend time with her. Its seems the more pregnant you get, the more infatuated she becomes with you.
