It turns girls into a clitboxes and yes does it work

Sasuko held her breath, Naruko was just in the box's range. If she were to move even by an inch she would be out, but she wasn't!

Sasuko proceeded to place the box on the ground, making sure not to make a sound as she did so. She then proceeded to do a series of hand seals before channeling chakra into the box and directing it towards Naruko.

Naruko barely felt Sasuko's chakra before she was engulfed in smoke, being sealed inside the box.

Seeing that her plan had worked, Sasuko jumped in joy before opening the box. The inside of the box was pretty bare, having only a mirror on the inside of the lid and a small platform that seams to be able to rotate, kinda like a music box with a dancing statue. But standing where the statue would be, was a clit.

Seeing the clit, Sasuko began to giggle as she channeled some chakra into the mirror. The mirror began to fog up before Naruko's face could be seen inside of it.

Naruko was confused, angry and couldn't move for some reason. She had been laying in the hot spring waiting for Sasuko's next plan before she was engulfed in smoke and putted inside some strange black place. Worst of all being that she could move a single muscles.

Before she had any time to think about escaping, light began to appear in front of her face. After her eyes adjusted to the light, she could see Sasuko's smug face inside of it.

"You bitch! What did you do to me!?" Naruko yelled at Sasuko, anger replacing all other emotion inside of her.

Sasuko, seeing her rival in such a state, laugh before answering, "Nothing much, I just sealed you inside of a box, but holding you captive isn't all it does. Wanna see?" She said, giggling to herself as she reached for something Naruko couldn't see from her limited field of vision. She couldn't see it, but she could feel it, Sasuko was playing with her clit!

Sasuko, seeing the look of surprise on Naruko's face, decided to explain herself, "The box I sealed you in is special. Special in the way that once your inside, you can't do anything. No chakra, no moving, nothing, you can only feel. It does allow however, to play with you body in a way..." Sasuko said as she closed the lid enough so Naruko could see her clit on the platform, "This rotating platform allows me to navigate to some locations on your body. Those include your pussy, your asshole, both of your nipples and of coarse, your clit. And I can do anything I want to then since you can't move. This mirror is the only other link between you and the outside world." Sasuko said, laughing at the look of despair and arousal on Naruko's face as she toyed with her clit. Sasuko then turned the platform until she was at Naruko's asshole, in which she then inserted an inflatable butt plug before switching back to he clit, leaving the butt plug stuck in Naruko's asshole. Sasuko gave Naruko one last look before closing the box and activating some stimulation seals that would stimulate any body part that was currently on the platform.
