Jessica looked at her fancy new computer. It had been a cheap piece of junk, until she'd written a bunch of upgrades on the side of the case. Now that she knew the pen worked, it was time to make some serious changes. She took off her shirt, looked down at her body, and sighed. Before she made any extreme changes, she had to fix herself up a bit first. She held out her left arm, put the pen to her skin, and paused. She assumed that it wasn't likely that the pen would interpret things *much* less pervertedly than she would, but she didn't want to run the risk that whatever magic the pen had would interpret something like "BOMBSHELL" literally. She started with "SEXUALLY ATTRACTIVE".
The effects were immediate. Her breasts became larger and firmer, her hair became long and glossy, and her legs became somehow both plump and toned. She looked in the mirror, and gasped; the pen seemed to have interpreted her words exactly as she would have liked. Seeing that her worries had been unfounded, she decided to get freakier.
She looked down at her belly, and wrote "HUNG LIKE A HORSE". The scent of musk stung her nostrils, as a monster horsecock sprouted from her crotch, above a pair of balls, above her unchanged pussy. Oh, no, it had taken her too literally... Who was she kidding, this was way too hot! But she knew other people might not share her tastes, and she needed to make sure she still fit in her clothes, so she wrote "HYPNOTIC" and "RETRACTABLE" on the side of her dick.
The feeling of the pen on her dick, and the thought of what she could do, got her super aroused. She had to try out her new dick right away! She pulled up an HD porn video on her computer, and started jacking off her new appendage. The feeling of climax was wonderful, but too soon, as she quickly covered the underside of her desk with delicious spunk. Seeing what a mess she'd made, she quickly wrote "ALWAYS CLEAN" on the desk, floor, and wall. The cum vanished; a bit of a waste, but she could always make more.
... Except that her dick was limp now. Not wanting to be caught unprepared for a jack-off or a fuck, she added "ALWAYS READY", and smiled as she surged back to full hardness.
What would she do next...
