The operative word being
"monster"
Dorothea wasn't thinking that children shouldn't play with dangerous tf toys
and instead locked the Transformation Room
to keep Ilvir and Kitty out of it
and went to her own private quarters in the huge secret complex
and locked the door behind her.
She wanted to take a shower after a long dusty day fixing machinery.
So she stripped naked and got into the shower.
Now back at the Sky Castle the Sky King got ready to summon the monster sized dragon
commonly called Storm.
The huge beast didn't actually lair at the Sky Castle
and all the Sky King knew was that when he tapped on an ancient
tuning fork he had found in the CloudPoint Citadel years earlier
the Beast would be summoned.
There was a village of troublesome rebel cloud humans who needed
destroying.
Down in her shower Dorothea was lathering herself with soap
when the "twinnnnnn"of that cursed tuning fork the Sky King
had just tapped rang in her bones and her
very atoms.
She screamed as she remembered the other forgotten transformations into her alter ego
Storm.
In a matter of seconds her DNA became that of a Giant Air Dragon male
and she barely had time to stumble out of the shower before her
feminine human breasts dissolved away in the rapidly
broadening well muscled chest of a mle
air dragon.
There was tht sensation of giving birth
as Storms dragonhood and genitalia
slid into position and
Dorothea uttered one last pitiful screech as
his body grew to his
glorious full size,he stretched his wings and roared happily as he realized he was Storm again.
The monster knew the altering private room Dorothea wrongly viewed as her own
It was actually his
Storms
private quarters once centuries ago
that this lair would not let sound escape into the rest
of the complex.
Ilvir and Kitty were none the wiser that their host
Dorothea had just turned into the most
feared entity the Storm of Death
Storm tiptoed to the secret exit only he knew about and leapt into the air and heared to see
what the Sky King wanted now
