Bigger big sister, BIGGER little sister

    by: infinity421 Author IconMail Icon
Hana stirred, slowly waking up. She wriggled about slightly before realising that she wasn't in her bed, and had fallen onto the floor during the night. Groaning, she stood up, only to realise-

I grew? Hana thought, realising g just how large her size increase had been. Wait until I show Chisa! I can't wait grow even bigger...

Hana trailed off inside her mind as her eyes registered the titanic sleeping form of her little sister, that was spilling out from Hana's bed, loud creaks coming from the frame whenever she moved. Hana shook her little sister as hard as she could, now much stronger than before. "Chisa, wake up! Wake up!" She said, while the giant six year old groaned and awoke. "Big sis? Why are you..." Chisa's eyes widened as she realised how much farther down Hana was looking at her bed the normal.

"Hana, you grew HUGE! Can we make you grow again? Pleeeaaase?" The gigantic child stood up onto the floor to give her sister a hug, only to stop, her eyes widening as she realised her new size. "Hana, look at me! We both grew bigger! I'm taller than the wardrobe, look!" Chisa took one huge stride towards the wardrobe, standing beside it, and towering half a foot over it.

Chisa gasped, "Hana, we can use the size chart to see how BIG we are! Come one!" Chisa grabbed her sister's hand, pulling her much smaller sister along on her quest for size. They both went into the storage room, the eight foot five ceilings offering a measure of comfort to Chisa. The size chart measured all the way up to the ceiling, and they took it in turns measuring eachothers height, discovering that Hana had grown to a massive five foot even, and Chisa to the titanic height of seven foot five, making her one of the tallest people in the world.

Suddenly, both of the girls' stomachs started to groan and rumble, and they felt themselves beginning to stretch out and fill the room to the brink...

How big the sisters get?
