Brazillian Altawoman Origin Short

This is a little something that's been fizzing around in my head for a few years. Gabriella Carvalho helps an old woman who has fallen in the street. Whilst walking her home, a strange mist seems to come out of nowhere, becoming denser until the world around the two of them becomes completely obscured. The mist suddenly clears, revealing not the familiar city streets but a marble chamber of neoclassical design. Hanging over a circular pit in the heart of the chamber is a Great Crystal, which seems to glow with a strange inner light.
"Where am I? What is this place?" Asks an astonished Gabriella.
"You are in the Temple of Transformation, child", says the old woman softly.
Before she can ask any further questions, Gabriella feels overwhelmingly drawn to the crystal. She approaches it, and as she does, the glow becomes brighter, and tendrils of energy start to stream from the crystalline surface. Reaching out with her hand, Gabriella feels her skin tingling pleasantly as the energy comes into contact with her. As she draws nearer to the crystal, the energy increases and more tendrils are produced, enveloping her. One bright strand of the pinkish energy trails down between her legs and, to Gabriella's astonishment, pulls down the zipper of her shorts.
Before her mind can process what is happening, the tendrils flow towards her midriff, travelling towards her most intimate parts.
Gabriella gasps as she feels the energy travel inside her via her vulva. Helplessly she becomes aroused, and the energy seems to radiate within her, infusing her entire being.
She feels her whole body starting to shudder. An orgasm is coming-- the biggest she has ever felt.
"What's happening to me?", she cries.
"A flower is blooming inside you, my child" says the old woman. "It is the gift of the Altawomen, germinating from within".
The orgasm comes like a shock wave, and Gabriella cries out in ecstasy.
Her breasts start to feel strangely full and heavy. Her shorts feel uncomfortably snug around her hips. Looking down, Gabriella cries out in shock-- she is growing! Her bare arms and legs thicken and then bulge with smooth muscle. Her breasts expand until they are stretching and spilling out from her tank top. Her thighs become broad and dense with muscle, and her glutes swell enormously until her rounded buttocks burst out of her shorts. Her short cropped hair flows into a long auburn mane, her tresses tumbling down a widening, muscular back. Her features subtley change- her eyes become darker, her nose and chin more pointed and her lips fuller. Gabriella sinks to the ground, moaning and masturbating as her clothing explodes away from her growing frame.
And behind her, the old woman is changing too-- she starts to rise, her hunched gait fading away as she stands tall. Her robe slips from her, revealing not a wizened frame but a much younger and muscular woman. A circulet of gold sits upon her noble brow. She is Lauress, Queen of the Altawomen!
Gabriella flexes her huge biceps and fondles the swollen mounds of her breasts in wonder. Then, as she draws herself up to her new and imposing height, energy crackles around her muscular body again and a golden armour appears, covering her nakedness.
Turning to face what she presumes will be the old woman Gabriella is confronted instead by the amazonian form of Lauress.
" You have been given our gift, Gabriella Carvalho. When you return to your world you shall return to human form, but you will be forever changed! For when you feel the stirrings of arousal within you, you shall feel the flower of Alta-Energy bloom once more and the transformation take place. You shall be.... An Altawoman!"
