Love the story! After reading the Demon Hunters story and another extreme fisting story here some time ago I have been looking for more of the same stuff.

Ah, that's one of my favorites.

If you haven't already, check out Ahemaru. Draws really wack stuff kinda related. Love the rare ovary play. Not a fan about the birthing though.
Maybe you can find some inspiration if you wanna go even deeper.
