Plugs?

Hermione pulled out two new plugs. Similar to the ones already in them.

Harry looked at them confused.

"Master can I pull out Hermiones plug and put the new one in? I promise it will be worth it." Luna said.

Harry nodded.

Luna smirked at Hermione who turned around bent over slightly. Luna grabbed her plug and replaced it with one of the new ones.

After Hermione stood up and turned around Luna whispered to Harry.

"Master call her a Bookworm."

Harry gave her a look but did as he was told.

"Bookworm."

Hermione gasped as her plug began to vibrate. She leaned against the wall as the vibration intensified.

"Both are keyed to words only you can say to activate. Mines Pudding. They vibrate until you say the stop word." Luna informed as she ignored Hermiones moans.

"Whats the stop word?"

"Do I have to tell you now? She's having so much fun." Luna smiled at Hermiones discomfort.

"Luna!!" Hermione gasped. She would tell Harry herself but the plug was making it hard to speak.

Harry smirked as Hermione gripped the bench in a **** grab. After a few seconds he decided she had enough.

"Alright Pet what is it?"

Luna pouted but told him. "Seeker."

He looked back at Hermione. "Seeker."

The vibration stopped and Hermione fell to the bench breathing heavy.

"Luna...that was evil!" She glared at the blonde.

Luna grinned wider but when she looked at her Master she realized she might have to be punished for that.

"Well it was a good demonstration. But Hermiones right that wasn't very nice. Hermione why don't you put Luna's plug in her and we'll test out hers?" He smiled at his bestfriend.

Hermione grinned wide and grabbed Luna's new plug. She spun Luna around and quickly replaced the the old one.

"Shes ready Master."

Harry smirked at Luna. "Pudding."

Luna gasped as the plug started. 'Fuck maybe I set the vibration to high! No wonder Hermione was going crazy!'

Luna grabbed the bench as the vibrations went through her.

Harry and Hermione watch Luna squirm and moan.

"Whats her stop word?" Harry asked.

Hermione pouted but answered. "Library"

Harry let Luna shake and moan for a few more seconds.

"Library."

Luna groaned as the plug stopped. She looked up at Hermione who was smirking at her. 'Alright I deserved that.'

"How far do these work?"

"You have to be able to see us but it should work from one side of the great hall to the other." Hermione answered.

"So you could be sitting in the library and not even know I there and it will go off?" Harry really liked that idea.

"Yes Master." Hermione was a little uneasy at his smile.

"I'm going to have a lot of fun with these. Thank you slaves for such a great gift."

Harry kissed them both. They dressed and started for the door.

"You know for a Bookworm and Pudding lover you're the best slaves a guy could ask for."

Both gasped as the plugs activated. They held on to each other as their master watch with a smile.

He let them suffer for a few seconds.

"Alright my Seeker training is done lets go to the Library."

They let out a relief as the vibration stopped. Even though Harry owned them they were suddenly worried how much more power they just gave him.
