It was one of her harder assignments. "You have 5 minutes to please me. Go." 

They racked their brain- hypnotized mind quickly shuffling through all of the things she enjoyed. They started by getting on their knees in a submissive posture and letting their eyes roll back in a way they knew she appreciated. They started to speak. "I'm yours. I'm helpless. I'm obedient. I do everything you say, instantly and eagerly. I'm your possession."

She suddenly stopped them. "What?" she asked. 

They looked at her. Her expression was peculiarly intense and a little surprised- like they had stumbled upon something that even she hadn't known she wanted. 

They looked her in the eyes. "I'm your possession, ma'am" they repeated, submissively. 

She practically growled. "Say it again". 

They loved to see her like this. 

"I'm your possession ma'am." they repeated. "You can do whatever you want with me." They tried to put all of that intention into their voice- really wanting her to feel their sincerity. 

"That's right," she smiled, cat-like. "I can. Why don't you keep saying that phrase? On a loop, please."

They found themselves begin to helplessly repeat it, over and over.

"I'm your possession"

"I'm your possession"

Their eyes rolled back again as the mantra took them deeper and deeper into more of an obvious trance. The memory of her pleased, hungry smile stayed with them even as they dropped further and faster, each repetition making the phrase more and more true. They gave into the sounds of their own hypnotized voice. The had done well. They were pleasing her. They delighted in their trance and their new mission, each moment making themselves more and more and more of a perfect possession for her.
