She's in the bag

When Rocketgirl next awoke, she couldn't see a thing. She blinked a few times to clear her eyes, but that wasn't the problem. She was surrounded by pure inky blackness. She felt leather beneath her and a layer of leather gently draped above her. Reaching up and around herself, she confirmed that she was completely surrounded by leather, her otherwise naked body cocooned in a loose leather sack.

She sat up, mostly to confirm she was unrestrained. But her freedom of movement proved irrelevant -- a swift kick to her face sent her sprawling onto her backside.

"No, Rocketgirl," Ms Jensen's voice spoke loudly, emanating from earbuds implanted in Rocketgirl's ears. "Don't get up. I want you lying perfectly still when we begin. That way I'll know exactly how much of your movements are caused by what happens next."

"What happens next?" Rocketgirl repeated anxiously. Her voice was muffled but perfectly audible through the thin leather sack.

"Yes," Ms Jensen replied, and Rocketgirl could practically hear her smirk. "Now that you're awake, I suppose we can get started. Now, hold still. If you can."

Rocketgirl heard a click as Ms Jensen's foot tapped a button. There was a loud whirrrrrrrr and a rush of air being sucked out of the leather sack.

Rocketgirl gasped with horror as she felt something she'd missed before: evidently there was a vacuum hose affixed to the leather sack just in front of her navel. The sensation of cool air brushing her navel as it rushed out of the bag and down the hose tickled, but Rocketgirl mostly felt fear.

Even as her hands grasped for the hose to try to find a way to unseal it from the bag, the leather rapidly collapsed around her. Ms Jensen kneeled down to pry Rocketgirl's hands from the hose and **** them to her sides so they would stay there as the bag deflated.

Panicking, Rocketgirl began hyperventilating, **** to get air into her lungs. She bucked and gasped, and Ms Jensen watched the leather constrict around her nose, her chiseled chin, her gaping mouth.

Soon the leather squeezed around Rocketgirl's perfect breasts, even her erect nipples defined by a layer of thing, strong, black leather. Ms Jensen stood up to watch the heroine, smothered head-to-toe in black leather, writhe and flail with limited mobility as she struggled desperately for air. Her knees bent less and less as her legs became more defined and straightened out. Ms Jensen watched gleefully as the heroine passed out, her body now perfectly defined by the tight leather surrounding it.

Kneeling down, Ms Jensen quickly drew a dagger from her belt and deftly sliced the leather open in front of Rocketgirl's gaping mouth and two flailed nostrils. Though the heroine could now breathe again, she did not awaken, which suited the villainess perfectly. She caressed Rocketgirl's easily visible cameltoe as her hand traced its way up to the hose.

She clicked the vacuum off but left the hose affixed to the bagged heroine. The hose would prove useful for the next **** she had devised for the troublesome heroine.
