A Throbbing Rebellion

Maple was daddy’s perfect little girl. Growing up, she had always gotten whatever she wanted. Luxury cars, lavish parties, vacations all over the world. It couldn’t have been more prefect. But after her eighteenth birthday, things started to change. Young men came knocking day after day, offering gifts and paying homage to her father. She was used to hushed negotiations coming from the guest rooms, but now she overheard her name being dropped disturbingly often. She felt different too. Her body was changing. Warmth was constantly building in her loins, her toys only providing momentary relief. In a matter of weeks her hips broadened and her ass swelled to the point that she couldn’t even button her jeans! Her once petite breasts swelled, straining her favorite tops in ways that She had never felt before. What’s more, her father seemed to be inspecting her every time he looked at her, smiling whenever her cleavage looked deeper than the day before.

Early one morning Maple found the truth. Ever since her mother died, her father had made her breakfast. She could hear him humming as she crept down the stairs, and everything seemed normal as she watched him though the crack in the door. But then she saw it. After a furtive glance around, her father dripped several drops of a bright pink concoction into her breakfast! A fertility tonic!

Maple’s heart pounded in her chest and her mind raced. What was she going to do? She had to do something! She had to get her hands on that tonic! But she couldn’t just grab it. She had to wait for her chance.

It was difficult to eat her breakfast as if nothing was wrong. Harder still to ignore the heat in her chest, the tightness. It was like she could feel the growth. Was it because she knew about it or had her father used a higher dose? She didn’t know. Either way, the hours crept by as she waited for night to fall, for her father to be asleep...

After midnight, once she was sure her father had retired for the night, maple carefully and deliberately snuck into her father’s study. To her blushing chagrin, she had to cradle her chest with her her arm to silence the clapping sound they made as she walked. She frowned. They were definitely bigger than they had been that morning. In the bright moonlight she could see blue veins crisscrossing them. She could almost see them pulsing with her heartbeat...
Maple shook her head vigorously. She was on a mission! She had to focus! As quietly as she could, Maple moved over to the desk, to where her father’s secret drawer lay hidden. And inside, there it was, a big pink bottle labeled "Fertili-Gro". "for blossoming young women into fertile flowers of Venus" "I can’t believe daddy would give me this!" Whispered Maple, biting back tears.

In the drawer there was another bottle. Glass, filled with a dark amber liquid. "Stallion", it read. "A couple drops with dinner for strength, youth, and virility," A thought popped into her head. A devious thought. "Perfect," thought Maple, smiling at the image of lifting her father by the collar with a set of bulging, powerful muscles. "A few swigs of this oughta make daddy reconsider!" Gleefully, she dashed back to her room with the two bottles. But in her excitement, she failed to read the fine print...
WARNING: highly concentrated. Do not consume undiluted. Do not mix with other elixirs without first consulting your doctor.

Back in the safety of her room, Maple opened the Stallion elixir, releasing a powerful, musky scent. "Oh wow," she gasped. The fumes were making her light headed. "Well," she said, pressing the bottle to her lips. "Here goes." First a sip, then a gulp, then another. It was like nothing she’d ever tasted before! She had to actively stop herself from drinking all of it.

At once the heat in her chest roared into an inferno. Her heart pounded with such force that she could barely set the bottle on her dresser without dropping it. "Whoops," she giggled, bracing herself on the dresser. "Maybe I drank too much!" No matter, it would be worth it if it taught her father a lesson. She could see herself towering over him, flexing her big strong muscles...

But something was wrong. She wasn’t getting bigger more muscular. If anything, the tightness in her breasts was worse than ever, and she could feel a strange tingling in her groin that was getting stronger by the second, and her hair was getting in her eyes.

"This doesn’t feel right!" Maple growled in frustration, trying to brush her hair out of her face, but it wasn’t- she stopped, staring at the thick lock of hair in her hand. She’d always had long hair, but this was longer than she’d ever had it, and getting longer! It was growing into a thick, wonderfully silky curtain that was racing towards her hips, cascading over her breasts- She gaped. Her tits were swelling, engorging. If they were big before, now they were enormous! Her poor nightie couldn’t keep up; the fabric was audibly straining, the seams popping. The pressure should hurt, but Maple felt good, really good. She caressed her bulging breasts, moaning with arousal.

throb.

THROB.

An indescribable ecstasy filled her. Something was pushing against her thighs, nudging them apart. Something warm and heavy. The ecstasy built and built, until strange new muscles clenched and she felt a wet, gushing sensation as droplets of something spattered her legs. With her one hair-free eye, Maple caught sight of herself in the mirror. Between her legs hung a massive black and pink mottled horse cock, surging and gushing as it continued to grow. The beastly organ was paired with a set of pulsating black testicles that had already surpassed cantaloupes in size. "Oh no, what have I done to myself?" Maple mused, widening her stance to accommodate the growth, only to find the weighty orbs pressing against her thighs again in moments. Her hips cracked and popped as the oversized organ continued to swell, dangling past her knees. Each rope of thick, sticky fluid that ejected from the glans of it felt better than the last. "It’s not even hard yet!" She moaned.

With a snap, her abused panties broke apart, falling in taters to the floor, followed shortly by the straps of her nightie, letting her heavy breasts hang free in all their glory on her heaving chest. The gleaming, pale globes still had the edge in size over her burgeoning testicles, though they were making a concerted effort to catch up, churning as if challenged. Maple caressed her magnificent, silky mane and admired herself in the mirror. She should have been shocked by her appearance, but it felt too damn good. This was perfect. Not what she had intended, but better.

She stared at the two bottles. A delicious thought came to mind. She bit her thickened, plush lip. The seam of her nightie rent apart as her beast cock surged erect. She had a very good idea of what to do with them.

Looks like daddy would get his heirs after all...
