When Lillian Met Zoe

On her walk around the city, Lillian came across an unsuspecting tall fit blonde woman, who was curiously looking at hunting magazines in a small store and couldn't resist the temptation.
"Taking a break from running to look at pictures of deer are we? How about joining those animals running around the forest.. except with a bit more tits included! I'll even let you keep your human looks." She thought to herself and started forming the spell.
Few moments later the life altering magic was ready and she let it fly towards it's target.

Lillian's quietly woven spell struck Zoe and her mind suddenly rushed full of pictures of deer and her human form mixing in with their graceful appearance, forming an absurd and erotic mix of both.
Despite the strength and intention of this spell, which would have been devastating to any mortal and would have even impressed capable witches, to Zoe this was just surface level magic.
She was a being born out of the very foundational energies that magic users merely called on. It would take a lot deeper understanding of magic to alter her form or to cause her harm.
Zoe's head slowly turned towards the now perplexed witch and with a smirk she said
"Right back at ya mate!"

Lillian's world changed. Never before had she been on the receiving end of magic such as this.
Even in this disoriented state she sensed the power of whoever had reflected it back, this thing wasn't human.
She found her body going through the exact changes she had planned for this woman.
Her bones quickly reforming themselves, her spine adjusting to a new gentle curve and forcing her on all fours robbing her of any ability to stand upright. Her feet and hands quickly elongating and forming into hooves.
Her breasts grew few cup sizes so they'd gently swing with every step, always tugging on her chest to remind her of their presence and whatever remained of her human form.
Her ass would enjoy fairly modest changes, becoming rounder and even more inviting for any potential lovers.
Last physical change was a pair of horns that definitely didn't belong to any deer, but they served as an added crown of humiliation to her form.
However the worst part was the magic. She could barely feel it anymore. It didn't respond to her commands or requests, as if it had been sealed away deep inside her, like a smouldering ember instead of the raging wildfire it used to be.

"Fucking hell mate, that's what ya had in store for me? Hah, I like it!"
In front of Lillian wasn't the woman she had cursed, but instead a tall talking kangaroo.
Before Lillian got a word out Zoe continued "Zoe's the name and granting wishes is the game!"
Lillian quickly understood what she was, this thing was a genie and worst of all not even an imprisoned one. Some idiot had actually wished this thing free!
"Mate I do respect the creativity of the spell, but you picked the wrong target. Now let me look into that messed up mind of yours.." Zoe's finger touched Lillian's forehead and she soon burst out in laughter
"Oh fucking hell, that mind of yours is one messed up place! You really have no restraint do you? I mean that church you messed with? Haha love it! Mate I think we'll become some great friends one day!"
Lillian had finally gathered enough of her wits to respond...

-The end

Very short story for you to go with this pic to give it some background.
I'll one day turn this into a proper long sequence/comic and actually finish this pic etc..
I've been working on a larger commission along with other stuff and that always eats into my productivity, but I wanted to get something done before the end of the month so here you go.

I want all of my characters to have some kind of interaction with each other or at least have knowledge of each other's existence and this also gives us an idea about their power levels and we'll see more of personalities etc..
Lillian punches above her class and age, but she's still just a witch and Zoe is something far more primal and magical. Not immune to being on the receiving end as we'll one day learn. (It's like wrestling, even the stronger guys have to lose sometimes.)
Perhaps this event will lead to some more magical self discovery and learning on Lillian's part.

PS. As a result of this, Lillian totally won't develop an intense fetish for being dominated by stronger magic users.
