Diana sits there, waiting for a moment. "I'm not sure where you should be kept... Hold on, wait. I know..." Diana grabs Jeff, shoving her in her diaper quickly.
Jeff isn't sure what's going on. All he knows is that Diana is moving quickly, and that he's being tossed around in the tight space. He ended up stuck in her vagina for a moment, before falling back out.
---------- Diana POV ----------
Diana ran, ending at her parents' bedroom. Quietly, she snuck in, careful not to make a sound.
Sneaking over to a closet, she found several objects, although she didn't know what they were for. She knew what her target looked like, however.
She found a belt, with a strange metal cage on the front. "There it is." Carefully, she closed the door to the closet. Then she sat down, turning on the light.
While she didn't know the intended purpose, she knew what she would use it for. She pulled her underwear down, and then her diaper. Then she put it on, noticing a key.
The key was already in a slot, which allowed adjustments. She strangely didn't need to adjust anything; It already fit fine. Picking Jeff out of her diaper, she placed him in the cage on the front.
Raising the belt as far as she could, she was confused. The cage wouldn't go past her vaginal area. "Oh well, at least this works!"
---------- Jeff POV ----------
Jeff didn't know what she was doing. He was picked up, and placed into the cage on the belt. Then she put it on... but stopped it where her pussy was. He heard her speaking about it working.
She pulled up her diaper, along with her panties. The cage pushed the diaper out a bit, but it was barely noticeable from the outside. In the metal cage, Jeff was stuck.
As Diana got up, keeping the key in the slot for easy access, she got up and walked out sneakily.
Jeff, stuck there, sat in darkness as Diana did her own thing.
