Growing like a Weed

It was Em's voice crying out. Hannah raced over to get a better view and immediately regretted doing so.

Em was hung upside down in a cage of gnarled vines. Her pussy was spread wide and filled to the brim with fibrous tendrils, some pumping dollops of a mysterious substance deep inside the girl's body while others twitched and thrust. This horror was enough to shake Hannah to her core, but it wasn't the cause of her wailing screams.

A new vine had joined into the fray, this one particularly strange. At its tip was a hollow translucent chamber containing a small, yet brilliant point of green light. The vine maneuvered above Em's crotch and unfurled like a flower. The little point of light fluttered out, landing right on top of the girl's clitoral hood.

"Eh...huh...eek! That tickles!"

Only Em could possibly start giggling and complaining about the tickles while being **** by some kind of demonic plant. The girl kept giggling and twitching, unaware that the cause of her discomfort was now on the move.

The little glowing speck navigated its way to the tip of Em's clit. There, it made use of a microscopic needle-like appendage. The little dagger jammed into the soft flesh, paving a way for the rest of the body to enter. Em shrieked from the pain, but was helpless to stop the invasion. Soon, the parasitic glow had embedded itself completely.

Em's clit pulsated nastily, the pink flesh now suffused with the green glow of the invader.

"Ugh, my clit! My fucking clit! It's gonna explode."

Em wasn't exactly wrong. Only a few seconds after the initial invasion, her little love nub began to engorge. Hannah knew what came next, but was helpless to stop it.

Em's clitoris sprouted like the step of a daffodil in early spring. It shot outward, packing on inch after inch. The tip plumped up while glowing green veins striated the stem. The burgeoning shaft grew gnarled and bumpy as it lengthened, making it resemble the surface of an old tree branch. Before long, the clit-turned-penis was even longer than Scarlet's, although it was much thinner.

The vines unceremoniously twisted Em over onto her belly, causing her throbbing pencil-penis to swing like a branch in the wind. Next, the vines shoved inside her pussy began to retreat, exiting alongside huge spews of slimy discharge. No sooner had these vines exited that two new masses began to emerge, each the size of small apple.

Hannah tried to look away, but found that she could not. There was something surreal about bearing witness to such traumatic and intimate moments of her friends' lives. She watched as Em's newly formed balls dropped. They were smaller than Scarlet's, yet still bigger than Hannah expected balls to be. The twin orbs glowed a strange and noxious green.

Immediately, a vine wrapped itself around Em's throbbing shaft. Another tickled her swaying balls. Em fought less than Scarlet. At first contact, she let out a confused, "oh!". After a few strokes, she was moaning and grinning like a little freak. Her eyes filled with the same green light that pulsed from her balls.

As if Em's transformation wasn't horrifying enough, the dark waters that obscured Becca were now receding. As they dispersed, they revealed a transformation equally as radical as the others.

Becca's skin was now incredibly pale. Her honey brown eyes were now two burning yellow lamplights. The change made her seem monstrous and alien. Like Scarlet and Em, Becca too had undergone a freak genital transformation. Her nascent balls were the biggest of the trio, hanging like ripe, glowing pomelos in a perfectly smooth sack of skin. Her penis was the shortest of the three, but it made up for it by being monstrously thick, resembling a small log.

Evidently, the watery mass had already begun to pleasure Becca before she emerged. She came out of her ocean cocoon already moaning and gurgling lasciviously. The dark waters reformed into a tentacle that stroked and sucked and caressed.

The glade was now filled with the lustful moans of Hannah's fallen friends. Only one hold out remained, but for how long?
