This is a short sequel to my earlier story Ginny's First Experience.
I suggest reading that first.
This story contains bondage.
--------------------

A few weeks had passed since Ginny’s first experience with bondage in the room of requirement. She and Luna had met a few more times to play, although Ginny always seemed to be the one tied up. She supposed it was because Luna’s other TUG partner always did the binding when the other two met to play. Speaking of Luna’s partner, Ginny still had not been introduced to her, although Luna had promised that it would happen soon.

Tonight, Luna and Ginny had planned to meet in one of the empty classrooms on the sixth floor for their game. Because she was feeling a little bold after her previous successful times tied up, Ginny had decided to deviate from the plan a little though.

Arriving an hour before she and Luna had planned, Ginny looked around the classroom and grinned. She originally considered trying to ambush the blond girl and force her to be the damsel this time, but Ginny had changed her mind when she found a particularly interesting spell in one of the library books.

Moving to the center of the room, Ginny shed the outer layers of her uniform until she was dressed only in her scarlet bra and panties. Then waving her wand in front of her, Ginny recited the incantation she had memorized earlier in the day.

“Conjurus Ropus Indecentio, Posit Span!”

Dark green mist spewed out of the end of her wand and began pooling at her feet. Gently tossing her wand to the side, Ginny braced herself as the spell began its work.

Thin tendrils of the smoke drifted upwards and wrapped itself around Ginny’s body at multiple places, pulling and guiding her body into a specific position. Her ankles and legs were pulled apart until her feet were slightly farther than shoulder width apart, and then the mist pulled upward, forcing her onto her tiptoes.

More mist went upwards until it reached her arms. Each arm was then pulled behind her, and then the mist forced her arms together until her elbows were touching behind her back. Ginny winced as the mist worked; her arms were now in a much more painful position than she had
previously experiences.

The mist now began to encircle her chest and upper body with thick bands that pressed against her skin. Some of the bands specifically targeted her breasts, forming a strict chest harness that made breathing a little difficult.

‘Wow, this is really intense. I really hope this wasn’t a bad idea…’

As Ginny began to worry, the mist forced her to bend at the waist so that her upper body approached the floor. When her torso was about halfway between upright and parallel to the ground, it stopped. As Ginny’s body had shifted, so had her arms which were now pointing upwards slightly towards the far corner of the room, still held in the harsh single bar.

Seemingly content with her overall position, the mist now started to reinforce Ginny’s bindings instead of adding more. More thick bands of mist began encircling her body, drawing intricate shapes across her form as they further restricted the small amount of movement she had left. By the time it was done, the mist had bands crisscrossing all over Ginny’s body from the neck down. In fact, the only part of the body it seemed to have mist seemed to be her head and her butt.

Speaking of her head, the mist began to creep upwards past her shoulders, forming a long collar around her neck that kept her head stuck in the same position. In full panic mode now, Ginny desperately tried to remember the counter-spell, but before it came to her, mist had forced itself through her mouth, forming a bit gag and silencing her.

Its job done, the mist settled into its final state. But whereas Ginny had been expecting the mist to take a form similar to rope, it instead hardened into something more akin to metal. The mist had in a way formed a Ginny-shaped cage around her, fully restricting her movement to nothingness, except for her toes and fingers.

Attempting to struggle and with the foul taste of the mist-gag in her mouth, Ginny groaned.
‘Great, now I’m stuck like this until Luna shows up. Not only is this near unbearably uncomfortable, but I can’t free myself in case someone else shows up. Please come soon Luna, please…’

---------------------------------------

Luna did arrive, about a half hour later. By then, the entirety of Ginny’s body was begin to get sore from being stuck in that one position for so long.

Of course Luna found the whole thing hilarious.

“I’m guessing you found the book in the library with the basic self-bondage spells? Yeah, someone messed with the book, switched out the basic ones with some pretty hardcore ones. Though I’m guessing you already figured that out.”

Luna took her time walking around Ginny’s bound form, soaking in the sight.
“Well, it would be a shame to let you out so soon. Plus you wouldn’t have really learned your lesson about being careful. You really do need to be taught a lesson.”

Ginny ‘mmmphdd’ into her gag, trying to get her friend to let her go sooner rather than later.

“Well, luckily for both of us, the version you happened to end up with is intended for spanking. So I guess that will be how you learn.”

Ignoring Ginny’s muted protests, Luna took her spot behind her red-haired friend and lightly caressed her bottom for a second. To Luna, it was pretty funny. Ginny had red hair, was wearing red underwear, and was about to have a red bottom.

“Alright, I think fifty will do. But I want you to count them aloud, alright? Don’t miss any.”

And with that, Luna gave her a rather hard swat on the butt.

*Swat*
“Onmmm.” Ginny winced from the sting of Luna’s hand.
*Swat*
“twmmmm.”
*Swat*
“thrmmm.”
*Swat*
*Swat*

“Tsk, tsk, Ginny, you missed one. Once again from the beginning.” Moaning in protest, Ginny tried to complain that the only reason she missed the count was because Luna had suddenly increased the speed she was going at by a huge degree.

As Luna continued to swat away at her already stinging butt, Ginny tried to keep count and realized as she missed one again that she was in for a very long night.

‘Here’s hoping I’ll even be able to sit in a chair tomorrow.’
