Chapter #13

Even Bigger and Needier Sister.

    by: Sophsoph23 Author IconMail Icon
You’re in awe and can’t help but stare at your little sister’s amazing body from the stairs. She’s so tall and curvy. She is the definition of the word “sexy.” She is there, laying in the middle of the living room, on her belly.

“Is someone coming to home?” you ask her shyly. “No, I was fooling you… No one is coming, because no one can be, and deserves to be, as big as me.”
Some minutes ago she was 12 feet tall, when she left the bedroom, and she must be around 16 feet now. She’s a growing girl after all, that’s a normal thing for a girl of her age… and she will keep growing far far larger.

Mia loves to grow, and you love the fact that she’s your “little”, or more exactly, YOUNGER, sister. You love it above the awesome fact that she’s a growing giantess. You love to see that a girl you used to cover with your shadow is now so massive. She’s dominant now, and you entirely depend of her will. She’s this goddess that makes you horny and that you want to fuck. But, to be honest, fuck is a big word, since your head is literally smaller than her nipples. How could you “fuck” such a colossal babe?

Your “little” sister loves to be big, she loves to caress her thick body, her constantly wiggling rump, her cowy boobs, her incredibly large hips, her awesome belly…
“How would you describe me Joe?” she asks smugly. You blushes, she is so impressive… “You’re beautiful, and I finally don’t know if you should stop growing. You’re so sexy… You’re like... my big sexy cow... Yes! Full of milks with her big boobs, and so fleshy. Your ass is so copious! I love you more than ever!” You finally achieve your sentence with this: “Please Mia, keep growing!”

Mia giggles and shows a big grin. “Mooooooooo! Yes big bro, I’m your growing fleshy cow! Don’t worry, I won’t stop growing! I’m a growing girl!”
Your little sister finally drinks the remaining growth sodas. But it doesn’t seems to affect her yet.

“Approach tiny bro.” she says, before putting you on her ass of giantess. You’re shocked and aroused. You’re laying on the young girl’s ass. Her buttcheeks are large enough to be a bed for you. “A true goddess…” you tell to yourself. You feel her growing constantly. Each time you blink, she’s slightly bigger than before. She must be growing a half inch per second. You’ve never been so horny. You remind how the sex with your girlfriend is… Ridiculous. Is Erin a wide-hipped 25 feet tall and still growing little sister with a face of angel? Is she so big that you could fit in her pussy? No, nothing of that. And her boobs are ridiculous. The only sexy girl that you want now is Mia. You’re amazed when you realize that “It’s only a matter of hours, if she wants it, for her to be tall enough to use a skyscraper as a toy, or even to flatten New York under her butt. She deserves to big this huge, she’s my goddess, my dear little sister.” You manage to remove your pants, before releasing a load in the large growing rear that you’re using as a bed. Mia giggles a bit, it tickles her. It’s a miracle she felt it, considering how enormous she is.

“I will leave the house, before it’s destroyed. It’s a bit hard to live in a lego sized home!” Mia says giggling. She farts (and smiles) before putting you on the floor, leaving you with a terribly bad but sexy smell. She then gets on all fours and creates a great hole in the wall to escape from the house, a hole that finally takes the shape of her titan sized back. “Ahhhh, much better!” she says, as she raises her freed body and stretches herself. This is the hottest show of your life: while doing this, she starts growing and growing at a pace faster than ever. You’re admiring her from behind, and you move away a bit to not being crushed by your young giantess. Her ass is plumping and wiggling dozens of feet above you. It’s a dream come true. She moans loudly “Biiiiig… I’m so BIIIIIG. I NEED to be BIIIIIIIIIIIIIIIIG… BIGGEEEEEEEEEEEER.”

“Wow… She’s so huge...”

Soon her spurt stops and she is a bit more than 80 feet tall (but still growing, obviously)! Her feet are like an elephant. You can’t believe it, she is so enormous that her large and wide butt could now flatten your house.

She looks below, impatient to find you and see your reaction. “So tiny bro, how do you find me ? I’m a well growing sis, right ?”
