One day, while at work, Dr. Maria met a young woman named Sarah, who walked into the clinic with a playful little puppy on a leash. The puppy, a golden retriever mix named Max, was bouncing around excitedly, and Sarah was laughing and trying to calm him down.

Sarah nodded, a look of excitement on her face. She dropped down onto her hands and knees, and then began to crawl across the room. Dr. Maria watched, feeling a thrill of excitement.

Over the next few weeks, Sarah brought Max in for several follow-up appointments, and Dr. Maria found herself looking forward to seeing them both. She enjoyed watching the way Sarah interacted with Max, and she found herself feeling a flutter in her chest whenever Sarah smiled at her.

Dr. Maria looked up, curious. "Of course, Sarah. What's on your mind?"

Sarah took a deep breath. "I've been wanting to explore some...different kinds of play with Max. You know, pet play. And I was wondering if you'd be interested in...helping me learn more about it."

Dr. Maria's heart skipped a beat as she considered Sarah's words. She knew that she felt the same way, and she was excited to see where their relationship would go.

One evening, as they were finishing up a play session, Dr. Maria turned to Sarah and said, "You know, I think I might be falling for you."

Dr. Maria took the collar and leash, feeling a rush of power. She put the collar around Sarah's neck, and then attached the leash to it.
