Skylar settled on an idea that they felt could be a lot of fun. Every human would be able to shapeshift their body whenever they desired, and to accompany this everyone would default to they/them pronouns unless they actively chose a gender.
A wave of warmth passed through their body, and they went to the bathroom, undressed and looked at their body in the mirror, fantasizing about having it change. Before their eyes, their pussy sealed itself up and balls moved inside it, while a penis protruded from between their legs and expanded to erection. They wished both it and their breasts away, and saw both their chest and crotch sink in on themselves until a flat, masculine chest could be seen and a vagina was again formed between their legs.
They felt like they could cry with delight. They'd made their body so they could control its sex characteristics! Eagerly, they started playing around with things. They gave themself breasts and a cock along with their vagina again, and they found they could remove all their sex characteristics, even giving themself no nipples and a featureless crotch.
