Mistress.

"I want to use Hermione all night. I want her for my slave for one night." Luna smiled.

"Interesting." Harry smirked. "Done. I'll tell Slut her role. You have my permission to use her however you want but no damaging my property, and you can cum as much as you want. But the plug stays in both of you unless you choose to fuck her ass with the toy."

"Thank you Master!" She lept on to him and kissed him hard.

Luna held his hand as she skipped out. She was a born slave but was curious what a mistress was like. Hermione was in for a very fun night.

Harry didn't expect this from her but he had learned to always expect the unexpected with her.

He may be down two slaves but luckily he had two more sluts and a lot of imagination to use on them.
