Mary gaped in shock as her sister began to add inches to her body, slowly rising higher an higher from her 5'2" to 5'5".
"Woah! This is awesome," Faye exclaimed, "how tall am I? How tall am I going to get?"
"I-I don't know. I don't know how much you drank," Mary stammered. Quickly thinking she added, "I have measuring tape in one of the drawers in the den."
"Ooo, ok. Be right back." Faye grinned widely and left the room, her footsteps sounding heavier as she left.
Mary sighed and quickly removed the fake label on the shrink vial and replaced it. She then took several long sips from the real growth vial and began to come up with a plan.
Meanwhile Faye went downstairs and rummaged through the drawers downstairs as her height slowly grew. By this point her shoes were beginning to feel uncomfortable and she kicked them off, noting that the hem of her pants were now below her knees, and her shirt was riding higher now.
"This is so awesome," Faye squealing in delight. Finally she found the measuring tape and held it up to herself, checking the length quickly as she heard the seams of her clothes begin to stretch. "5'11" and still going strong," she smirked. SHRIPP! Faye heard the seams of her pants tearing as the inches piled on and on. "Maybe there's more improvements I can make to myself." She caressed her body thoughtfully as the pleasurable growth continued. "Bigger boobs, a bigger ass, or maybe something....more exotic." The ideas flooded through her mind as the sleeves of her shirt tore apart from her expanding arms. "I want more," the now 6'3" Amazon exclaimed and began her ascent upstairs.
