It was a Sunday when the incident happened. Samantha had planned on spending the day lounging around and reading a new book, but as soon as she woke up, she knew something was off. She started to feel a tingling sensation throughout her body, and her nipples were hard and sensitive. She tried to ignore it, brushing it off as a nervous tic, but as the morning wore on, the feeling only intensified. She tried to distract herself with her favorite video games, but her mind kept wandering back to the strange tingling in her body.

As the hours passed, Samantha began to grow restless. She could feel something inside her building up, like a pressure that needed to be released. She paced around her apartment, trying to burn off the energy, but it was no use. She was desperate for something that she couldn't quite name.

Finally, Samantha gave in to her desires. She reached down and began to rub her clit, gently at first, but then faster and faster as the sensations grew stronger. It was incredible. She could feel her body responding, growing hotter and more sensitive. She was so engrossed in her own pleasure that she failed to notice that her clothes were getting tighter around her swelling curves.

Samantha moaned as she touched herself, completely lost in the bliss of her own body. She felt her climax building, and as she came, she cried out in ecstasy. But instead of relief, she only felt even more restless. She needed to release whatever was inside her, and she had no idea how.

Samantha decided to go for a walk in the park, hoping the fresh air would help clear her head. But as she made her way down the street, she could feel the tingling in her body growing stronger again. She tried to resist the urge to touch herself, but as the sensations grew stronger, she couldn't help it. She ducked into an alleyway and began to rub her clit through her pants, feeling the relief wash over her. She was so caught up in her own pleasure that she barely noticed that her jeans were getting tighter around her growing thighs.

As Samantha came again, she could feel the tingling in her body growing even stronger. She knew she needed to stop, but she couldn't bring herself to. She unbuttoned her pants and slipped a hand inside, feeling her swollen clit pulsing with need. She was so close to another orgasm, and she couldn't hold back any longer. Wet, sloppy sounds filled the alley as Samantha fucked herself, desperate for release.

Just as Samantha was about to come, she felt a strange sensation in her breasts. They had always been large, but now they felt heavier, almost as if they were growing. She looked down to see that her shirt was stretched tight across her swelling chest, revealing her hard nipples through the thin fabric. She couldn't believe what was happening to her. Was she really growing?

Samantha's thoughts were interrupted by the sound of her pants ripping open. She looked down to see that her thighs had grown so large that they had burst the seams of her jeans. Her feet were also growing, pushing her sneakers to their limit, and her toes were visibly straining against the material. She was still touching herself, and as she came again, she felt her body grow even faster.

Samantha knew she needed to stop, but she couldn't bring herself to. She felt drunk, unable to focus on anything but the pleasure coursing through her veins. Part of her had always wanted to be bigger. When she was in high school, she was the tallest girl in her class, and people used to tease her for it. But secretly, she loved the way her body looked and felt. She liked being big, and had been disappointed when puberty ended and she stopped growing. Now, it seemed like her dreams were coming true.

As Samantha came again, she felt her body swell even larger. Her clothes were barely holding together, and her bra tore apart, sending her heavy breasts tumbling inside her t-shirt. She reached down and ripped off her top, exposing her massive tits to the world. She pinched one of her dark, long nipples, and moaned as she felt it grow even longer between her fingers.

Samantha looked down to see that her breasts weren't the only things that were growing. Her thighs were getting thicker, squeezing her fingers together as she continued to fuck herself. Her butt was also getting larger, practically inflating as she grew. She could feel her pants ripping away completely, and she didn't care. She just kept touching herself, moaning as her body swelled even faster.

Samantha was so engrossed in her own pleasure that she didn't notice the guy who was watching her from the other end of the alley. He had been walking by when he heard the wet slapping sounds and decided to investigate. He was shocked to see the woman fucking herself in public, but as soon as he saw her swollen breasts and thick thighs, he knew that he couldn't look away. He reached down and rubbed himself through his pants as he watched her grow.

Samantha looked over to see the man jerking off, and it was all she could do not to touch herself even faster. "Hey there," she said, her voice breathy and thick with need. "It's okay, you can come closer." She loved the way he looked at her, his eyes wide with lust. To her, he looked like a little kid, barely taller than her waist, and she loved it. She loved how short he looked, and how he seemed to be getting smaller by the minute.

As the man came closer, Samantha came again, sending a shock wave of growth through her body. She could feel her feet expanding, ripping through her sneakers and bursting out of her socks. Her feet had always been big, and she always had to buy them in men's sizes. But now, they were bigger than any she had seen before, man or woman, she thought. She wiggled her toes, loving how sensitive they felt as they swelled to cover the remnants of her destroyed footwear.

"Oh god, did you see that?" she asked the man. "I think my feet are getting even bigger! It feels so good." She reached down and touched the man's face, loving the way his cheek felt against her swollen finger. She was so turned on by his smallness that she could barely think straight. She wanted him to worship her, to kneel down and kiss her growing feet and tell her how big and powerful she was.

But instead, the man backed away, clearly overwhelmed by her size and power. He stumbled backwards, his eyes wide with shock. Samantha giggled, loving the fear in his expression. In fact, she felt an extra rush of pleasure from his terror, like it gave her a boost. She reached out towards him, teasingly, and he turned and ran away, leaving her alone in the alley.

Samantha realized how big she had grown, towering at least twenty feet tall. She felt incredible, her body still growing and expanding as she touched herself. The walls of the alleyway seemed to be closing in, and she knew it was time to go somewhere else. She stepped out into the street, feeling the pavement tremble beneath her weight. As she walked, people looked up at her in awe and fear. She loved it, feeling their eyes on her bare, swollen breasts and her massive thighs. Traffic came to a standstill, and people stood staring as she walked past. Samantha couldn't help but stare back at them, loving the way they looked like toys from her enormous height.

But as Samantha stood there, she felt that tingling sensation building up inside her again. This time, it was more intense than ever, and she issued a deep, rumbling moan as she began to touch herself once more. She needed relief, and she needed something to help her get it. As she continued to grow, she spotted a nearby streetlight, and she realized what she wanted to do. She walked up to the light and pressed her enormous, dripping pussy against it, grinding against it like a horny animal. The metal groaned and creaked as she fucked it, and the pole slid between her breasts, causing her to cry out in pleasure. She could feel the tingling in her body building up again, and this time, she felt like she was going to explode.

Samantha came, and she came hard. She screamed as she grew even faster, her body inflating to enormous proportions. She lifted the streetlight, now slick with her juices and bent at a weird angle, and pressed it against her pussy. The sensation of the metal on her swollen clit was incredible, and she came again, sending a wave of cum cascading down her legs and onto the pavement.

By the time Samantha's orgasm ended, she was close to forty feet tall. She looked around at the chaos she had caused, and she realized that everything looked so small and insignificant. She reached down and plucked a car from the street, holding it like a toy. Well, I guess it is a toy now, she thought to herself. There was still someone in the car, and she peered in, loving the fear in their eyes. "Don't worry," she said, "I won't hurt you. In fact, I think you're going to like this." She pressed her enormous nipple against the window. She could see the person inside, a man, trembling with fear. "It's okay," she said, "I know it looks big, but you can take it. Just open your mouth."

The window shattered, sending glass everywhere. The man inside screamed as her nipple filled the space where the window had been, and Samantha laughed as she felt her breast grow even larger. Her soft flesh seemingly oozed into the car, pushing the man further and further back. He tried to fight it, but he couldn't stop her. She was simply too big.

Samantha pulled her breast out of the car, revealing the massive dent that had formed in the driver side door. It looked like another car had slammed into the side, but she knew that it was just from her giant, growing boob. She reached down and touched her nipple, squeezing it gently between her fingers. She loved how soft and sensitive it was, and she loved the look of terror in the man's face as he saw her unmistakably grow even bigger.

Samantha wasn't done with the man yet, however. She brought the car down to her waist, and slowly, teasingly, pushed the front end of it against her pussy. The metal creaked and groaned as her pussy lips spread open. The car was still too big for her, but she knew how to make it fit. She began rubbing the hood of the car against her swollen clit, sending waves of pleasure through her body. She could see the man inside, his eyes wide with shock and awe. She loved the way he looked, so small and helpless.

"Ooh, that feels good," Samantha moaned, her voice deep and powerful. "Do you think it'll fit?" She grabbed the front of the car and pushed it forward, and the hood crumpled against her pussy lips, slowly pushing itself inside. The metal scraped against her flesh, and she loved the way it hurt. She could feel her pussy stretching, and she knew that it was working. She pulled the car back slightly, and then pushed it forward again, this time further than before. She could see the man inside, his head pressed up against the windshield, as if he was trying to escape. But there was nowhere to go.

Samantha fucked herself with the car, pushing it deeper and deeper into her pussy. With each thrust, she grew bigger and bigger, her body expanding to fill the street. Her breasts were blowing up like balloons, and she could barely see what she was doing, they were so huge. She could feel her nipples growing longer, poking out at least two feet in front of her, and she loved it. "Ugh, my tits are so huge," she moaned. "Look at how big they're getting! I bet I can even suck on them now."

Samantha could now hold the car in just one hand, and she started to move it in and out of her pussy faster and deeper. She could hear the metal groaning, the man inside screaming, but she didn't care. She just kept fucking herself, growing bigger and bigger with each thrust. With her free hand, she heaved one massive titty up to her lips and began to suck on her own nipple, sending a wave of pleasure through her body. She could feel her breast inflating, felt the weight of it increase as she sucked harder and harder. She was close to coming, and she wanted to feel her whole body explode with pleasure.

Finally, Samantha came. Her pussy clenched around the car, crushing it completely, and she could feel her body growing even larger. She looked down at the man, trapped inside the tiny, crumpled car, and smiled. Somehow, he survived. "Thank you for helping me grow," she said. "You're a good little toy." She dropped the crushed car to the ground, and he scrambled out, his clothes ripped to shreds and his face covered in sweat and dirt.

Samantha's thighs trembled as she looked down at the chaos she had caused. She was so big now that she barely fit between the buildings, and she could see people running away in terror. She was almost drooling with desire, and she knew that she wasn't done yet. Her feet were bigger than cars now, and she could finally do what she had been dreaming of. She lifted her foot and brought it down on top of a fleeing car, crushing it like a bug. She loved the sound of the metal crunching beneath her sole and the pop of the tires. She brought her foot up again and repeated the process, loving the way it felt to be so powerful. She was the biggest thing in the city, and she loved it.

"This is amazing," Samantha said, her voice echoing through the streets. "I can feel myself getting even bigger! It's incredible!" With each step, her breasts grew bigger and her hips swelled even wider. Her pussy dripped with cum, and she loved the way it felt to be so wet and horny. She loved being a giantess, and she never wanted to stop. "Look at me! I'm unstoppable! I'm so big, I can do anything I want!"

Suddenly, a helicopter appeared overhead. It was followed by several more, and Samantha realized that they were government vehicles. She knew that they would try to stop her, but it only made her hornier. She wanted to put on a show for them, to show them just how powerful she was. She reached up and grabbed her breasts, squeezing them hard and rubbing her nipples back and forth. Her body lurched upward with a sudden rush of growth from the stimulation, and the helicopters scattered to avoid her.

"Oh god, it feels so good!" Samantha screamed. She could feel her body getting even bigger, her feet covering several cars at a time. Pretty soon, she wouldn't be able to walk down the street at all without destroying the buildings on either side. The thought made her horny, and she reached down to rub her clit again. She could feel her pussy lips expanding, dripping with cum, and she knew that she was close to coming again.

The helicopters returned, this time with something new. "Samantha!" a voice called out over a loudspeaker. "You need to stop what you're doing and come with us!" Samantha couldn't see who was speaking, but she recognized the voice. It was her mother.

"Mom!" Samantha replied. "I can't stop growing! It feels so good!" She rubbed her clit even harder, and she could feel another orgasm building up inside her.

"Please, Samantha!" her mother begged. "You're destroying the city! You have to stop!"

Samantha feigned concern. "Oh, you're right, Mom. But how can I stop? My boobs are so big, I can't even see where I'm going!" She grabbed her tits and squeezed them, sending a wave of pleasure through her body. "Ooh, they're so sensitive! I think they might be getting bigger, too!"

Suddenly, Samantha felt something sting her shoulder. She looked down to see a dart sticking out of her flesh, and she realized that the government was trying to stop her with tranquilizer darts. She began feeling drowsy, and she knew that they had gotten her. She fell to the ground, the impact shaking the earth and destroying the nearest buildings.

As Samantha lay there, she felt strangely euphoric. Whatever drug they had given her felt incredible, and she couldn't help but touch herself. She stroked her clit, and she could feel her body growing even faster. She was lying on her breasts, and she could feel them swelling against the pavement, growing bigger and starting to push her up. "Uh oh, Mom," she said, her voice thick with desire, "I think the tranquilizer is making me grow even faster! I can feel my tits getting bigger, and I'm getting so wet!"

Samantha's body continued to grow, her legs extending further and further behind her. She could feel her toes, each as big as boulders, plowing through the streets and smashing cars to pieces. She needed to come, and she reached down to rub her clit again. She could feel her pussy lips pushing up against the ground, and she knew that she was growing faster than ever.

"Stop what you're doing, Samantha!" her mother pleaded. "You're destroying everything!"

"Am I getting too big, Mommy?" Samantha teased. "How big am I now?"

Samantha's mother was speechless. Samantha was now close to 100 feet tall, and she had grown so thick that her thighs were pushing buildings aside. Her breasts were like enormous bulldozers, crushing everything in their path. She was hornier than she had ever been in her life, and she could feel another orgasm building up inside her.

"Oh no, Mom!" Samantha moaned. "I think I'm gonna come again!" With a devious grin, Samantha's massive eyes rolled back in her head, and she let out a scream of ecstasy as she came. Her body expanded so fast that it seemed to explode, sending shockwaves through the city and causing buildings to collapse in on themselves.

Samantha was now bigger than anything else in the city, towering over even the highest buildings. She loved the power she had, and she never wanted to stop.
