Things go as planned, Alison gets bigger and bigger and protects you

By: GiantessLover

Over the next few months, Alison has been servicing your sister Kim. Almost every day she kept showing up, bigger and bigger. You could tell she was enjoying every inch however she was always gentle with you, even though she insisted on being on top, she would always control her weight so she wouldn't crush you.

Soon she was 20 feet tall and she moved into the barn. She explained to your parents that she probably caught your sisters growth disease, but she would provide for herself, however she had no place big enough for her to stay and due to Kim and her love for your girlfriend, she convinced your parents to let her stay.

Kim still **** you to pleasure her as well, but she wouldn't cum on you anymore, she would always feed it to Alison. Alison kept her promise to not let Kim get too rough with you as well as explore her growing body. Her K cups soon turned into M cups. Much to your relief she didn't become a Futanari like your sister is.

One day while your sister took a walk in the woods, you looked up at your 30 foot girlfriend and asked her why she wanted to be big so badly.

"Well lil man. I always had a fantasy about growing. I was always the tallest in my class, even taller than my parents when I was only 15! I was sad the day my growth spurt ended. I found forums that told stories about my particular....addiction to growing. I was so jealous of Kim. She was growing and growing and it wouldn't stop! Then she did what she did, and I started growing again! It was such a good feeling towering over people, my clothes feeling tighter every day. I love to grow hunny, its such a turn on for me and I can tell you like me bigger as well."

You couldn't deny the effect growing had on your girlfriend. Not only did she get taller, her confidence grew, her curves got curvier and best of all, she loved you dearly. She kept your sister from abusing you, and she made sure you got to enjoy her bigger body just as much as she was.

Nothing could go wrong.....could it?
