Touch of the Divine (Futa on Female Stories). Futa on Female Stories (Lesbian Futanari), #40

Demons have ravaged the world, leaving only destroyed cities and pockets of human resistance. In a last-ditch effort, Felicity goes to the temple of Ignitia, an ancient fire goddess who once protected humanity-but had abandoned them for unknown reasons. Legends say that Ignitia's magic could cleanse the demonic taint. But it requires a sacrifice, one of flesh and desire. And once Felicity stands before the goddess, a being of unparalleled beauty and power, she is more than willing to pay the price of salvation!
