Futanari Supergirls: The Chaos Angel - Futanari Supergirls, #3

Shay Tate and Nikki Jones, or perhaps as we now ought to call them, Stormwing and Galaxy Girl, have fled. They are only gradually beginning to learn more about why their bodies have changed to include certain aspects of male anatomy, why they have suddenly developed superpowers, and perhaps most importantly, who else has taken notice of their new abilities. Galaxy Girl realizes that they have a new member, known as the Chaos Angel, and after a brief respite in a place impossibly remote for mortals, they go to find her... This 10, 400-word story is part three in a series.
Each will be available separately, and as five-part anthologies once each sets of five is complete. In general the series will feature futa-on-futa, futa-on-girl, futa-on-man, and gender swap elements. This one features futa-on-futa. This story depicts adult characters consensually engaging in explicit sexual situations. None of them are related, either by marriage or blood relation.
