Follow Luna.

Hermione stood outside the room. Luna was on the other side waiting.

She had on a tight leather outfit. Her bare pussy exposed and her tits hanging out. Two pieces of tape over her nipples.

"About time Slut!" Luna said. "Get those clothes off!"

Hermione stripped fast and stood with her hands behind her back. Her collar back to normal.

Luna came up and grabbed the brunettes huge tits. "You're so fucking hot." The smaller blonde took a nipple into her mouth.

"Oh...thank you Mistress."

Luna smiled. "Tell me the truth. Does this turn you on as much as it does me?" She moved her fingers down to Hermiones very wet pussy.

"Yes...I'm surprised but it is sexy to call you Mistress."

"Yay." Luna kissed her hard.

Hermione moaned against the blonde who owned her for the night. That was still odd but she was really turned on by it too.

"Now get the bed Slut!" The small blonde lost all sweetness. She was in full Mistress mode.

Hermione practically jumped to the bed and laid down. Her hands and ankles were wrapped in rope and she was spread eagle. Fully exposed and displayed.

Luna climbed on the bed and began assaulting the bond bookworms large tits with her mouth and hands.

"Huge fucking tits for a bimbo slut." Luna purred as she played with them.

"Fuck..."

"Shut it." Luna sat up. "No talking unless I say so Slut." She slapped both tits hard making Hermione groan. "Master Harry says I can't be to rough with his property but I have so many ideas to **** you."

Hermione went a little pale there.

"Oh don't worry a slut like you will love them." Luna 'reassured.' "I know you worship cock but tonight you worship me." She pulled slightly on Hermiones collar. "Understand?"

"Yes Mistress." Hermione nodded frantically.

Luna smirked down at her. "Now what to do to you first?"
