Chapter #4

Leah

    by: The Underling Author IconMail Icon
"Oh my God Dan, are you even trying?" your sister mocks as you struggle to pry the gun from her grip. You had to admit quietly to yourself that her strength was incredible - she was a slender build, however even this modest increase in height had made her much more powerful than you'd thought. As a burst of water shoots out from the gun, you notice that the majority of the spray douses your sisters face. She shrieks in surprise but deep down, she realises what this means... and so do you.
Her body wastes no time in reacting to the water, and you immediately notice her arms thickening faster and the weight increasing. She suddenly starts to laugh.

"Hahaha! You stupid fucker! You're going to get it now!". Her friends cheer her on while a small crowd begins to form around the spectacle. Leah's growing body very soon becomes too much to handle, both figuratively and literally as you find you can no longer restrain her when one of her hands grabs your wrist and twists it hard... harder than you've ever felt before and probably made worse by the fact that her hand is growing faster and faster as it holds your arm. Leah stands up as you try to do the same, and suddenly the difference in size is apparent. You look up at your 'little' sister in fear, up at her mischievous grin and past her bulging bust which threatens to bust free of its bikini constraints.

"Woah Leah, you're a fucking giant!" says one of her comrades from behind you. Other people are muttering and gasping too, but this statement echoed through your mind as you came to realise... your sister actually had become a giant! From 9 feet tall, her stature was daunting, and she appeared to be growing still as she shoved you to the ground with ease, causing laughter all around.

"What's the matter, big bro?" she asks you sarcastically. "Were you trying to steal from your poor little sis?" she continues while gesturing with the water gun. Dumbstruck, you didn't say a word as your swelling sister took a step toward you, appearing to grow larger and larger still. She places one of her huge feet on your chest, pinning you to the ground with ease as she gradually starts to shift all of her weight on you. Breathlessly, you plead with Leah.

"Fuuuuck! Leah... please..... get off!"

"What's that, little Danny? I can't hear you!" she retorts.

The immense pressure on your torso brings a tear to your eye as your heavy sister grows larger upon you. Fortunately, it appears that her expansion is coming to an end. The only problem now was you were about to have your bones crushed under Leah, and even if you got out of this position, there was no way you were strong enough to take the gun from her now.

"So, what to do now, little brother?" Leah muses from high above.
