Amazon Planet 9: In the Temple of the Lost Ones - Amazon Planet, #9

The Amazons have gone in search of the Futanari, and for the first time, Maggie Kennedy, the former Earth woman-turned-sex-slave for the Amazon Queen, has traveled beyond the walls of the Amazon city, elsewhere on the planet Amaza. They are following Celena, the first Futa they've had among them in thousands of years. But Celena has gone missing, and the Amazon Queen asks Maggie and several of the other slaves to go find her...
with the danger of losing themselves in the process... Once the Amazons and the Futanari lived in a harmonious symbiotic relationship, and if Maggie has anything to say about it, they will again. But first, she has to find and rescue Celena...(This 6, 600 word story contains depictions of primarily futanari scenes, all of whom are consenting adults in sexual situations, none of whom are biologically related.
It is part nine in a series, so the story may not make sense if you have not read the previous parts--although a summary precedes the actual story. Every five parts will be available in a five-part anthology, as soon as they are complete.)
