A special collar

As you sit in your office, your machine arrived. As you read the instructions, you smirk. Just then, Olivia walked in into the room, wearing a strapless red checkered dress(https://preview.redd.it/poiei65u5c371.jpg?width=828&format=pjpg&auto=webp&s=73d165b5affdf7aaca11aac7aa4af5e82440cfc2), and greets you, "Good Morning Mr Doe, You called for me?"
"Ah yes, Ms Rodrigo, please, take a seat"
Olivia sat down
"So, Olivia, I just want to say, I really admire you and your talent, and I would like to offer you a proposition. This proposition will give you around 690 Million straight up,4 million a year, and not just you, but your family will be provided for."
"Wow! Thats... a really generous offer Mr Doe. But there has to be some stipulations right? And this job...its gonna be tough?"
"Well, a part of the Job Scope is that you won't be able to, or at least extremely rarely be able to meet your family, and when you're not producing songs or acting, you're going to be very busy, and you'll basically have no free time."
"That doesn't sound great... but for that amount of money.....well, what is the job?"
"You'll be my house pet, my slut, my maid, my ****. To the public eye, You'll be my wife. You'll do anything I make you do and more."
Hearing that, Olivia chuckled, "Thats funny Mr Doe, no seriously, whats the job."
"Two things, one, I'm serious, and two, from now on, you call me Master"
Olivia immediately tensed up, "I'm sorry Mr Doe, but no! I am not and will not be your sex ****!" She then got off her seat and moved towards the door
"Not so quick ****. You need this money, and don't act like you don't know what I'm talking about. Your father has a debt. Take this job and the debt is gone, and he'll be well provided for for the rest of his days."
Olivia stopped in her tracks.She then turned back and sat back down.
"and not to mention, if you don't take this offer, I can and will ruin your career, so consider wisely."
She sat down, thought it out, then said " I want another 0 behind that amount of money, and I want control over my job there. You can't **** me to do things I don't want to do, which means no sex. I can be your maid, and take care of you but no sex."
Hearing that, you smirk, "Of course, I can do the first, but not the second. I'm not paying you 6.9 billion to be a maid."
Olivia thought about it, sighed, and nodded. "Fine"
"Excellent"

"Now, I'll need you to sign this contract. It stipulates all your responsibility as my, "personal assistant" for legal reasons, sex **** to be crude" Contract(below)

Olivia skimmed past the document, then sighed, cursing her luck, then signed the contract
"Excellent puppy, now, put on this collar."
Olivia looked at the collar with disgust, swiping at it with her hand. "I'm not putting that shit on me! We're in public"
"Puppy" you said menacingly, staring at Olivia as she slowly shrank back,"you forget your place puppy. This will be your first warning. Third onwards, it will be extremely unpleasant for you."
"Y-Yes Mr Doe"
"Thats warning number 2 puppy, tread lightly."
"Sorry....master" Olivia said, blushing slightly
You pass her the metal band, bigger than even her head.
"Umm, how will this work Mr-I mean Master...its too big"
"Just put it on puppy, Master will take care of it. You see puppy, that collar, and other machines you'll see soon, are controlled by my mind"
"Yes Master"
As she puts the band around her neck, it suddenly shrinks, to fit snugly around her neck, leaving no room for her neck to move about, and just then, the front of the collar read, "Olivia, Pet **** of John Doe"
"Master,I thought you didn’t want people to know I was your ****"
"Don't you worry about that puppy. This collar is more impressive than it looks, it's one of the strongest metals on earth, but as light as air, and it has a few functions. It can give you a dose of anesthesia or an aphrodisiac, it has a shock function, and even a kill function"
Hearing that, Olivia's face showed **** panic, but you quickly said, "but dont worry, I'll rarely use the shock function and hopefully I'll never have to use the kill function. As long as you're a good pet for master, it'll be fine. Carrying on, the collar also can shoot out a leash that can be of any length, and will be attracted to my hand, and lastly, to spare you of the embarrassment, it is also becomes invisible.
Hearing that, Olivia took a sigh of relief
