There is the sound of keys at the front door, Amanda is startled. She was now as tall as me but she was starting to shrink. I grabbed her hand and moved towards the stairs, her ample cleavage began to disapear as her breasts dropped a size and her Dress's low cut front lifted up towards her neck. The hem of her dress dropped down to the top of her knee and her legs shortened, she was now about 5'4. I was going to take her to my room to stop the shrinking but i gave up as I watched her body return to her natural state. The Deadbolt of the door clicked,the door opened, and my Katie, my sister walked in. She was a well developed long legged brunette, and to top it off she had a very high IQ but she used her body to get what she wanted. 'Well what do we have here' she asked with attitude.
