A penis!

As the skirt hit the floor, Liz gasped as she discovered the source of her discomfort.

Attached to the spot just above her pussy was a penis, she could tell it was the source from the fact that it was blush red and from a numb heat in the back of her mind she knew was emanating from it. The penis sat there pulsating slightly as if waiting for something, Liz could barely think over the numbness that was clouding her mind, trapped in a warm fog as she desperately struggled to get a grip on her situation.

Liz could barely keep a cohesive thought when she recognized her hand moving down towards the pulsating member, she watched as time slowed to a crawl as her hand drifted down to her groin, her eyes lazily tracking it on its decent until the moment of equilibrium when the very tip of her finger contacted the skin of the penis.

The moment the finger made contact, a dam of sensation bursted forth from her penis crashing trough out her entire body, it flowed its way into every crevasse of her body, she felt her dicknipples strain with arousal as it made its way up her torso towards her head, the numb fog that lay over her mind was flooded away replaced with a deluge of pleasure and pain, of fiery heat and blistering cold. she felt her whole brain come alive with activity, she felt a moan start to escape her mouth, turning into a low below as the entirety of her body relaxed all at once, forcing her body to fall back onto the bench of the changing room.

The sliver of conscience that stored away at the very center of her mind was captivated with the scene that was unfolding before her, she watched in awe as her penis imminently started growing, pulsating more and more as it grew from the shell that it was before. Liz watched with unfettering fixation as the shaft expanded, growing from 2 inches, 3, 4, 6, 10, until it capped out at what must have been 14 inches. She felt it thicken as it grew, adding more and more girth as it lengthened until it was as thick around as her forearm if not more, she could feel her balls swell out between her thighs, growing and churning with seed until they where the size of grapefruits.

Liz hazily gazed at her now knee length cock as it started to drool thick streams of precum, she felt the heat and sensations die down from the growth that she was able to get a hold on her mind.

"Oh my god." she gasped as she caught her breath, she felt her racing heart beat start to slow down as she stared at the ceiling.

She looked down at her body, her dicknipples rising and falling with each breath, the tips gleaning as precum rolled down their lengths, she beheld the sight of her new cock, gazing at it as if rose a fell in time with her dicknipples, thick streams of precum still drooling down onto the floor, she caressed her swollen balls feeling the churn of cum from within them, she shifter her balls to the side and was relieved to find that her pussy was still moist with pleasure.

"This is the best day of my entire life" she mused as she basked in the afterglow.

As Liz sat up to start enjoying her newfound length, a sharp jolt passed through her mind reminding her of where she was.

"oh crap" she gasped as she stood up, her cock bouncing up and depositing more precum onto the floor.

Liz quickly realized that she needed to get home if she wanted properly test out her new tool, she tried the put on her sweatshirt but her dicknipples wouldn't retreat back into her breasts no matter how hard she tried to calm down and her cock pitched her skirt to the point where anyone could get a full view if her groin from any angle.

If she wanted to go home she needed to take care of her members, but she couldn't do it here, she had to find someplace to safely dispose of all the cum she might expel, now that she has a cock.

Liz quickly grabbed her sweatshirt and skirt and headed for the changing room door.
