Yes

Hermione was red when she picked up her collar and attached it.

To everyone, but Luna and Harry, she was fully dressed but she knew she was completely exposed.

"Yay!!" Luna said as she grabbed Hermione and kissed her.

Harry smiled at the sight of his naked slaves snogging.

"I admit Hermione. You surprised me here." Harry said as they stopped the kiss.

Hermione blushed and stuggled against Luna's naked body. "I don't know why. I just felt compelled to try it."

"Well hope you can live with your choice. Because you're not getting dressed again until tomorrow. For the rest of today and tonight you're a naked collared ****."

Hermione went a little pale at that realization. But if her master ordered it there was nothing she could do about it.

"It will be okay Hermione." Luna reassured. "You'll love being naked all the time too. Soon you hate clothes as well." Luna sqeezed Hermiones ass.

Hermione didn’t quite have Luna's enthusiasm but was very turned on by the idea.

"Well girls ready?" Harry asked as he put all the girl's clothes in his bag.

"Yes Master." The said together.

Harry walked behind them. Admiring their bare asses as they left the relative safety of the locker room.

Hermione was crimson red all over her body as they entered the hallway.

Luna was smiling ear to ear as the air moved over them. Her nipples hard and pussy aching.

And Harry was fighting another erection as their tits and ass moved down the hall.
