A collar

A thick black collar with the word **** in big white letters.

Luna felt the heat rising between her legs as she began to remove her clothes. Slaves didn't wear anything but their collars and she was a good **** to her master.

It didn't take long to undress as she didn't own any undergarments anymore. Her master had made her throw them all out and she loved the feeling of the freedom of not having to wear them.

Once she was nude she strapped the collar around her neck and it locked into place. Only Harry had the small key so it would stay until he released her.

She immediately turned and took her place. On her knees in front of her master. The chill of the room was only partly responsible for her hard nipples but did nothing to calm the moist heat between her legs.

Harry ran his finger over her head.

"That's much better, don't you think, pet?"

"Yes, Master." Luna didn’t look up until she was told.

"Did my pet obey her rules?"

Luna hesitated. Her rules were clear.

No undergarments

Always sleep nude

Not touching her pussy other than cleaning.

Never have any pussy hair.

Never cum without permission.

There were others when they were alone like now, but those were the ones she had to obey outside. She was hesitant because she broke the 3rd.

"I played with the pussy that you own." She couldn't call it hers. "I tried not to, Master, but last night's session made me weak."

"Did you cum?"

"No, Master." She was barely able to stop herself but she did.

"Good. You did right telling me, but you broke the rule. You know what that means." Harry smirked. He loved this next part.

Luna ached with anticipation. She loved and hated this. Her punishment.
