You try to find a way to get the pills

    by: Oswald Author IconMail Icon
You were in a state of shock at what had happened. How could this be? Your sister growing 6 inches and a pair of boobs overnight? This went against everything you ever thought possible or believed about science. It was incredible, it was terrifying. Most of all, it was intriguing. You wondered if the GrowTech company knew what kind of product was on their hands and your mind raced thinking of all the applications it had. Soon, there would be no more short people as everyone would want to grow bigger. The NBA would probably be dominated by people taller than the hoops. But you were getting ahead of yourself. For now, there was only one person that mattered -- Molly.


You had to find a way to get those pills back from her. She was already a little crazy but there was not telling what she'd do if it meant she could grow bigger. And you had no idea if the pills were addictive or anything.


You crept downstairs, where Molly was absorbed by the fridge, looking for stuff to eat. Her butt swayed back and forth and you felt embarrassed by the boner growing in your pants. She had a great-shaped ass, it was a shame she was your sister.


You looked on the counter but the pills were nowhere in site. Suddenly, the fridge door closed and Molly smiled at you.


"Looking for something?"


"Uhhh..."


"It wouldn't happen to be *this* would it?" She asked, holding up the pills.


"Actually, yeah. I think you should stop taking those, Mol. They could be dangerous and as your big --"


"Big brother? Hm. Mayyybbeee for now, but certainly not for long. Especially since I just took a double dosage of both pills. Mmmm I think I can feel a growth spurt about to come on. Wanna watch "big" bro? Don't think you'll be able to contain yourself when you see these tits get even bigger."


She smirked and looked at your boner before wolfing down a slice of pizza and burping loudly.

Her eyes glittered and she kind of tensed up.

"Are you okay?" you asked.


"It's.. happening... again..."
