As you stood there admiring your outfit, you saw Mary walk over to a desk and pull out a weird looking collar. When you turn around to look at her and ask what it is, you see her pull out a phone and press a few keys on it. After she's done, she puts the phone back in her pocket and sits down on a chair

"What is that collar, Mary?"

Mary grins and waves the collar in front of her.

"This baby is a neat little device that we use sometimes to find ourselves new animals for the zoo. Now, usually, we wait until the guest has finished their visit before we offer the option to become a part of the attractions, but when we get a guest that receives VIP status, we offer a little challenge to them. The challenge goes like this. I'll show you the command on your watch to stimulate all your pleasure zones and you have to resist cumming for a full ten minutes. If you lose, then after I take you on a really special tour of the zoo, I have to privilege of collaring and tagging you as my personal pet and loaning you off to the zoo from time to time."

You look at her shocked.

"What about me going missing? If I don't return back after this, people are going to coming looking for me and-"

"And no one will find or probably even care. This establishment didn't get to where it is without help from powerful people with lots of money. Plus, I'm sure that you do find this challenge intriguing. Otherwise, you would have just flat out said no. If it makes you feel any better, this challenge isn't required. It's just that, a challenge."

You walk over to her and sit down on a chair opposite her with your arms folded.

"Good to know, but you've only told me what will happen if I lose. What's in it for me to accept the challenge. A.K.A. What's my prize for winning?"

Mary smiles and raises her arms up in the air.

"Me. If you succeed, I'll become yours. Instead you getting this special collar, it'll be put on me. As part of the prize, I'll also enter that chamber and get refitted into a new latex outfit, with you deciding what it is. Once I'm outfitted, I'll take you on your tour of the zoo, as your guide, and then, when you leave, I'll be going with you, as your lifelong pet."

Mary leans forward and wiggles her eyebrows.

"So what do you say? Are you a brave tigress or just a little scaredy-cat?"
