Do something with the zipper tab (lz)

Placing the knife down on the floor, Plum re-approached the girl.

Guiding the girl on to her knees, she turned the zipper tab around in her hand, still skeptical at what she'd seen. The girl's breathing seemed to grow quicker, despite the vibrations from moving about having died down.

Imagining in her head how silly she must look, Plum pushed the zipper tab tentatively against the back of the girl's neck.

Nothing seemed to happen. There was no resounding 'click', no magical beam of light or rematerialization of an ethereal zipper... but there was no buzzing either. The girl sat patiently, her breathing quick and short.

Plum pulled her hand back, expecting the zipper tab to follow her, but it stuck. It slipped out of her hand. now hanging off the back of the girl's neck.

A strange chibi in a wizards hat appeared in Plum's subconscious mind, waving jazz hands and creating rainbow words that said "MAGIC!" above its head. Plum dismissed him, focusing instead on reality.

No longer sure what to expect, she closed her thumb and forefinger around the tab of the zipper and pulled down.

Her heart began to beat faster and faster as the zipper began to "unzip" the suit, a slit appearing where there wasn't one before. Beneath the black material was pale, naked, human skin. A lock of red hair was pressed up against the girl inside the suit, drenched in sweat and some other slippery liquid.

Plum continued to unzip the suit, freeing the girl trapped within. She pulled at the zipper down until it ended halfway down the girl's back. Almost immediately, the zipper tab melted into the suit once more, disappearing completely.

The girl's breathing was quick now and it was clear something was getting her worked up. Plum stood back as the girl reached for the hood of the suit, digging her fingers into the back of her head. She watched as the girl pulled the latex apart, two halves separating like slices of pizza, leaving behind rubbery black tendrils that refused to allow her actions.

With a sharp tug, the suit's 'helmet' split in the back and the girl's head emerged, her grunting and heaving suddenly audible outside of the tight suit. She turned to Plum, her eyes conveying not gratitude, but sorrow... almost apologetic.

Both girls shared a moment of hesitation before the now free redhead hastily stood and pulled herself out of the suit, mumbling something Plum couldn't quite make out.
