Bonnie descends into madness

The bed creaked violently, threatening collapse as its monstrous occupant rocked back and forth in a reverie of lust. The growth had finally subsided after nearly forty five minutes. The plant no longer pumped its subject full of chemicals. She had reached her full potential and God what a potential it was.

Prior to her encounter with the plant, Bonnie Andrews had been an attractive young woman standing five feet five inches in height and weighing approximately one hundred and fifty pounds. She hated exercise and generally avoided gyms and weight rooms like the plague. One time for gym class she had been **** to do a bench press and she barely got the girl's bar up for five reps. She came to accept her weakness as part of her being. She didn't need to be strong or athletic. She was kind of pretty (when she tried) and very smart and those qualities were enough.

The plant had turned Bonnie into a monster. That's how Bonnie felt about the situation, at least. The bed that once comfortably fit her now seemed ridiculously small, as if it were built for a young child. She felt massive. Her arms and legs rippled with thick, vascular muscle. Given how far her legs extended past the end of the bed, she must have been well over six feet. God only knew how heavy she was now. Every time Bonnie moved even the slightest bit, the bed, the walls, the floor, everything shook!

Bonnie moved a lot, too. She couldn't help it. Her entire body burned with a frenzied, unnatural lust. It felt so alien in comparison to how it used to feel. Bonnie remembered how she used to have to coax pleasure out gently with soft rubs of clitoris. It never came easily, and when it did, it was never enough. That was before Bonnie switched teams.

Bonnie glanced down between her legs and let out a forlorn moan. How could this be possible? How could that freakish thing be growing out of her?

The newborn shemale's cock had continued to grow until it reached a truly inhuman length. It measured nearly fifteen inches from base to tip and was as thick as a small tree trunk. Fat, bulging veins ran along the surface, allowing large quantities of blood to be pumped into the leviathan organ. The glans was an ugly purple thing as big as a baseball. Beneath Bonnie's cock, where her vagina should have been, dangled a pair of softball-sized testicles. Each ball glowed faintly with forbidden power.

The plant had several vines wrapped around Bonnie's thick manhood and was vigorously jerking her off. Slimy pre-cum dribbled from the tip of the shemale's cock, soaking the covers below. Bonnie could feel herself building to some frightening crescendo and there was nothing she could do to stop it.

"Let go of me!" Bonnie cried.

Her voice startled her. It was so deep now! As deep as a man's voice, but with the softness of a woman's.

"I said let go!" Bonnie demanded.

She reached out with massive, burly arms and tore at the vines on her dick. After a short fight, the vines ripped off with ease. Bonnie was shocked with how quickly the plant-flesh tore under her grip. However, the plant wasn't finished with her. It reached for her, sending half a dozen fines straight at her cock. Bonnie kicked and punched, in the process falling off of her bed.

Bonnie landed on her knees and felt the entire house shake under her weight. Strangely, the fall didn't hurt at all.

A moment later, the plant landed on Bonnie's back and redoubled its ****.

The plant had succeeded in Bonnie's physical transformation, but her mind still fought her new masculine urges. It realized now that it would need to be more aggressive.

"Get off of me!" Bonnie shrieked. She tore at the plant, but for every vine she ripped away, three more took its place.

More needles erupted from the plant body, jabbing into Bonnie's skin. This time, they pumped something a little different into her body. Blood surged into Bonnie's veiny cock, causing it to grow so hard the skin felt like it was going to explode. Her balls throbbed and glowed. A moment later, something clamped down on Bonnie's head.

Voices erupted in Bonnie's mind.

Fuck! You need to fuck!

"Stop it! Shut up!"

Find a pussy and fill it!

Images of slick, glistening vaginas and bulging tits filled Bonnie's mind. How had she never noticed how sexy women were? Now that she had gone over to the other side, the thought of plowing some wet, horny girl drove Bonnie nuts.

Bonnie thought of Allie. Of her mother and sister. Of all the hot fucking cheerleaders at her high school. So many pussies to fill!

"No! Stop! I don't want to do that!"

Fuck them! **** them! Pump your seed into them!

More of the plant's wicked juice pumped into Bonnie's veins. Suddenly, her lust turned to anger. A rage unlike anything Bonnie had ever felt washed over her. It made her feel like she had lava in her bloodstream.

Fuck every pussy you find!

"No! I don't want that. I love Anthony...he...he...fucking did this to me!"

No, that's not right. It was an accident!

However, the more Bonnie thought about it, the angrier she got.

"It's his fault I'm like this! He turned me into a freak!"

As Bonnie's rage built, so did her lust.

"I bet I have bigger cock than that pathetic little fuck. I could probably break him in half! No, wait, what am I saying? This is so wrong! I can't...I shouldn't...I want him! I want to fuck him too! I'll fuck everyone. Fuck. Fuck! FUCK!"

Bonnie roared as jizz rocketed out of her cock, splattering the opposite wall. Her orgasm was so fierce, so primal that it shook the entire house. It was cataclysmic. Apocalyptic. But it wasn't enough.

With ease, Bonnie ripped the plant off of her and threw it against the wall she had just jizzed on. She was done with its crap! She needed more. One paltry orgasm wasn't enough. She needed more! A good tight pussy would do the trick.

Bonnie ran naked through her house, her massive cock swinging back and forth. In her rage, she smashed picture frames and decorations, overturned tables. It felt so goddamn good to be strong! She towered over the world now, bulging with god-like muscles.

When Bonnie reached the front door, she didn't bother opening it. Instead, she opted to give it a strong push-kick, sending it flying off its hinges.

"Fuck I feel good!" Bonnie howled.

She ran off into the night, led by a hungry cock that wouldn't rest until it had gotten its fill of pussy. Bonnie's rampage had just begun.
