Collars?

Hermione pulled out of her bag a pair of collars similar to the ones they already wore.

Harry gave them an odd look.

"Let me show you." Luna said. "Slut put mine on please."

Hermione buckled the collar around Luna's neck and suddenly she was fully dressed.

"Touch her Master." Hermione said.

Harry reached out an ran his hands over Luna but didn't feel any clothes. Only bare skin.

"The collars make it look like we're wearing clothes. We can enchant you glasses to always see through it. I'll be naked and collared all the time now and only you and anyone else who wears a collar will see it!"

Luna was gleeful at the idea of never having to put on clothes again. Hermione was hesitant at the concept.

Hermione took off Harrys glasses and waved her wand at them. When he put them back on he saw Luna completely nude except her collar.

"That’s impressive girls. How do you know no one else will see through the charms?"

"We tested it Master." Hermione blushed.

"How?"

"Luna wore it. Just it in front of the Headmaster." Her face redder by the thought. "And I wore it without my shirt in front of Snape."

Sure she was terrified Dumbledore or Snape would see but nothing came of it. Luna was trilled to be naked like that. Hermione was starting to think the blonde had developed an exhibitionist kink too.

"What!? They didn't notice?!"

"No. You know Snape would say something."

"I don't know whether to reward or punish both of you for doing something like that."

Harry looked at them and was very turned on by the idea they were naked and only he could see it.

"Master can I wear this the rest of the day? Just the collar please?" Luna begged.

Harry knew she hated clothes now and was always **** to dress after their fun.

"The collar is charmed to work as long as it's locked on and only you have the key so as long as you don't remove it from her anywhere public she will be covered Master. It also has a warming charm so Luna wont get chilled being nude." Hermione informed him.

She too knew Luna hated clothes and some of the sessions left her want to not dress either but wasn't sure she could do like Luna wanted. Being topless in front of a professor was terrifying enough but completely naked? She didn't know if she had the guts to do that.

Harry was contemplating his options. Luna naked around so many people and them being unaware was both thrilling and a little frightening as well.

Should he let his **** run around naked like that?
