A film studio

You arrive at the film studio of a rather new company, but it seems to have plenty of budget.
The director is still in a meeting so you're all on your own, waiting. You didn't have to prepare anything for the audition so it was probably just going to be some improv.
The amulet you're wearing weighs heavily on your chest, heavier than before...
You start sweating. "Maybe it's just the nerves", you think.
But suddenly you start feeling dizzy and you feel yourself changing...

You're hair grows  longer and starts getting in your face. You're a blonde now.
Your chest expands to two big mounds of flesh, your new breasts...

Your lips get thicker and your hips expand. Before you even realize what's happened you notice that your clothes are also changing. You're now wearing a flowery top with a short, white skirt, your ass barely fits in it! You take a look in the window and you finally see your new reflection. You're a MILF!! And no matter how hard you try, you can't not look sexy... Your lips seem like they were made to suck some juicy cock.

You curse: "Fuck!" Your eyes widen. As you try to think of an explanation for this situation you notice that you're getting very, very horny. You want to feel your new body, the urge to touch yourself is so high. You look up as you here a small cough. It's your director! He looks you up and down with lust in his eyes. He's an ugly man, kind of scary.
"We can start the audition, your co-star has arrived. So remember, your role is Wanda. A desperate housewife in need of a good, hard fuck. Your husband doesn't love you. Your children don't love you. You can only get some love from that sweet, thick cock."

Your eyes are wide open. What does he mean? 

Your co-star comes in, a handsome, well endowed black man. He takes of his pants and shows you his penis, the scene has started. Your body seems to move as if you're used to this kind of work.
You take his penis in your hand and start "working".

You start to get into it. You see the director nodding happily.
"Now fuck him."

In one quick move your co-star slips his big cock in your MILF pussy. You gasp,
IT'S SO FUCKING BIG
You can't handle the pleasure it gives you.

The director calls out angrily: "At least try to look as if you enjoy it!"
You smile.
Who are you to deny him? He's your new boss after all.

A mansion

You arrive at gigantic fancy mansion. It's the property of a very rich family you had never heard of before.
You get in, no one is home yet, they have left the instructions on the kitchen table. You start cleaning right away, it's not your favorite job, but it's something.
You start sweating. "Maybe it's just the nerves, the first day of work", you think.
But suddenly you start feeling dizzy and you feel yourself changing...

You're hair grows  longer and starts getting in your face.
Your chest expands to two big mounds of flesh, your new breasts... Your ass and legs get so thick you feel start getting off balanced.

Your lips get thicker and turn bright red, your hips expand even more. Before you even realize what's happened you notice that your clothes are also changing. You're now wearing a short dress, your ass barely fits in it! You take a look in oven window and you finally see your new reflection. you're a curvy MILF!! And no matter how hard you try, you can't not look sexy... You try to get your dress below your ass but it seems impossible.

You curse: "Fuck!" Your eyes widen. As you try to think of an explanation for this situation you notice that you're getting very, very horny. Thinking about your rich boss makes you wet beyond belief.

You want to feel your new body, the urge to touch yourself is so high. 

You start touching your new pussy. It's old, used... dripping wet... It's so sensitive... Your moans are loud, but you don't care.

You look up as you here a small cough. It's your new boss! He looks you up and down with lust in his eyes, who know how long he has stood there. He's a handsome man, rich, powerful...

"I came to check on you. Didn't your read the instructions? You should have started undressing as soon as you got here." 

And who are you to deny him that.

You walk over to him and push your big, saggy breasts in his face.
"As you wish sir."
"Master.", he corrects you.
"As you wish, master."

An Office

You arrive at gigantic office building. It's a rather new company, but it seems to have plenty of budget.
The CEO is still in a meeting so you're all on your own, waiting. The amulet you're wearing weighs heavily on your chest, heavier than before...
You start sweating. "Maybe it's just the nerves", you think.
But suddenly you start feeling dizzy and you feel yourself changing...

You're hair grows a bit longer and starts getting in your face. Your turning blonde!
Your chest expands to two big mounds of flesh, your new breasts... They rip open the buttons on your shirt, your new breasts spilling out of your clothes.

Your lips get thicker, your hips expand. Before you even realize what's happened you notice that your clothes are also changing. Your pants turn into a short skirt, your vest changes to a pink colored vestand all of a sudden you're wearing sexy stockings! You take a look in the office's window and you finally see you new reflection. You're a curvy, young babe... And no matter how hard you try, you can't not look sexy... (The fact that your breasts don't fit in your clothes might have a role to play in that.)

You curse: "Fuck!" Your eyes widen. As you try to think of an explanation for this situation you notice that thinking starts getting extremely hard... You feel yourself getting dumber and dumber.
You can't believe it... The more you try thinking, the hornier you get.

You want to feel your new body, the urge to touch yourself is so high.

You start cupping your breasts. They are so sensitive... Your moans are loud, but you don't care. You don't have the space in your brain to think about that, not anymore.

You look up as you here a small cough. It's the CEO! He looks you up and down with lust in his eyes, who know how long he has stood there.

"Well Miss MacQueen, I think you're hired. So you shouldn't worry yourself about that. Just continue now, we'll get to work soon."

And who are you to deny him that.

a high school

You arrive at the local high school and you go into the principal's office.
She's still in a meeting so you're all on your own, waiting. The amulet you're wearing weighs heavily on your chest, heavier than before...
You start sweating. "Maybe it's just the nerves", you think.
But suddenly you start feeling dizzy and you feel yourself changing... 

You're hair grows longer and starts curling, your chest expands to two big mounds of flesh, your new breasts...

Your lips get thicker, your hips expand. Before you even realize what's happened you notice that you're also wearing new clothes now. A black dress to be precise and a vest.

You curse: "Santa mierda!" Your eyes widen. You try again: "Qué carajo."
You can't believe it... You're speaking spanish! You try to speak English, but Spanish seems more natural. You have to think very hard to speak your former mothertongue and the words all come out in a very thick accent.
You take a look in the office's window and you finally see you new reflection. You're a hot babe, a hot teacher... And no matter how hard you try, you can't not look sexy...

You want to feel your new body, the urge to touch yourself is high, but you hear the door open.

The principal enters, an old and stern woman.
"So Miss Rodriguez. I have looked over your application and it seems like your the perfect woman for the job. You can start today. I suggest that you start by having a meeting with Mister Gomez, he is the other Spanish teacher and you should get to know him. He's in the room on the other side of the hallway."

You walk over to the room where Mister Gomez is in, perfectly balancing your steps on your new high heels. You walk in. She didn't warn you, she didn't tell you the other Spanish teacher was a total hunk. You get wet instantly, your new pussy is tingling.

He looks up to you: "Yes?" You can't help yourself, you start undressing.

You answer in a very thick accent: "The principal sent me, we should get to know each other better if we're to work together." 

And that was the start of you're very, very succesful career as the new Spanish teacher of your local high school. Everyone loved you, or at least the male students and collegues did.
