meanwhile in her room

She felt her ears twitch beneath her hair, but paid it no mind. They were starting to stretch outward into fox ears soon enough they would emerge closer to the top her head while the race of her body finished remolding itself even the hair surrounding the ears was growing thicker already reaching to her shoulder and moving forward the brown hair was also shifting in coloration too with purple streaks spreading & overriding the natural hair color quaking in both fury and exaltation of the burgeoning power that filled her Kiara could feel her clothing wrapping tight around her body the petite figure she posses was changing into a far more sensual figure to fit her demonic persona hips were widening out while limbs stretched forward in every part causing the clothing to either pull back or stretch outward though it was uncomfortable, she paid it no mind even as her gaining height was causing tears to emerge each tear revealed more skin which was going through a color alteration too much like her now darkening hair the once fair skin tone was shifting into a strange bluish pallor that was not possible for any human to possess naturally but what she was becoming was quite unnatural & she felt her mind embracing all these changes the violent and destructive impulses which once scared her were becoming something she found increasingly pleasant her misgivings before were starting to appear as nothing more than a trivial worry she felt empowered & ready to carry out this destructive impulse that burned inside & let loose all the frustration as human she had been nursing deep inside a twisted laughter escaped her lips which had darkened to match her skin alteration eyes were not alight with delight at the acceptance of this cruel & manic disposition emerging from her long hair the fox ears twitch at the sound of her clothing tearing apart but she paid them no mind, even amused at the feeble rags that desperately clung to her body stretching herself as her body continued to mold itself, she let out a content hum at the sensation of her emerging buxom hands reached out and cup them to sinful delight while they clutched these massive orbs the nails on each finger started too stretched outward even more were patches of fur that spread down the fingers & hands to cover much of her lower arms this fur matched the same color as her hair the same fur burst forth out of her footwear while her stockings were torn when the furs continued the spread up her leg they stopped just below her thighs which had blossomed out quite generous more so above was the spreading rump that taxed the pitiful remains of her undergarment but that was nowhere as noticeable compare to the huge bushy fox tail that emerged forward & waved mischievously in the wind Feeling her power & change reached a peak Black Fox delighted in her freedom before a sudden icy chill struck her she immediately grimaced in agony at the cold metallic sensation that manifested across her neck, wrist, & ankles materializing out of the air through magic, a massive manacle appeared over each spot powerless to stop it, she felt them clap tightly against her flesh before being filled with a sudden drain of power collapsing down to the ground Black Fox winced in annoyance at the remnants of the magic that was used to bind her power away again being asserted still the fleeting moment of weakness pass & she was able to stand up though her power had been constrained the binding was no longer able to hold her back completely tossing back her long hair Black Fox held up one of her hand to conjure up some power in a destructive all of flame though weakened, this power was still sufficient enough to deal the destruction she desired a wicked gleam reflected in her eyes and Black Fox set out to cause some destruction & mayhem once more
