Futanari Supergirls 4: Black Fang and Sonic Sword - Futanari Supergirls, #4

Nikki Jones and Shaylene Tate have slowly come around to the realization that they can never go back to the simple college girl life they had once enjoyed, before the strange transformation that changed them into not simply Futanari, but Futanari with superpowers. Their lives have been a whirlwind since, as they've learned what they could about their new abilities while simultaneously avoiding capture by the police and every government on Earth.
Alongside a newly discovered Futanari, The Chaos Angel, little by little they discover their new abilities and discern a little more of the truth about the ancient cosmic being that transformed them. Their world is about to change again, though, as superpowered beings with lethal intentions make landfall on Earth, intent on pursuing the Supergirls... This 15, 000 word story is part four of an ongoing series.
It is a superhero comic-style story where all the heroes and villains are Futanari, featuring Futa-on-Futa, Futa-on-man, and Futa-on-woman couplings, in pairings and group scenarios. All characters are over the age of eighteen, none are related by marriage or by birth, and all characters engage in all acts entirely consensually. All stories will be available as singles, and also available as five-part anthologies upon completion.
That out of the way, I hope you enjoy!
