Amy changed into her gym clothes and drove to her gym. She had a session with Lucy, her trainer. Lucy was around 34 but still looked young, she had really short white hair and an amazing body. Amy met up with her and while Lucy wasn’t looking Amy emptied her water bottle and filled it with the growth water.
Amy wanted to grow Lucy first and then she’d shrink her back to normal later. Before they started, Lucy took a sip from her water. Amy smiled as while they were doing stretches, Lucy, who was only a little taller than Amy had already grown a head in height. Amy soon was only face to face with her chest. Lucys gym pants were also stretched and gave a good outline for her ass. Her top had also stretched.
Lucy didn’t seem to notice any changes through out their workout. They had a break and Lucy drank half of her water. Her growth had sped up and soon her head hit the ceiling. Amy was surprised her clothes were still on, almost as if they were growing with her. Lucy rubbed her head and laughed it off as a growth spurt. She must have been 9ft now. Amy was trying to lift some weights and Lucy came over to help her pick them up. Amy was face to face with her crotch. Lucy had to hunch over to stand in the gym and soon had to sit down. She couldn’t do much so she ended up doing some push ups. Amy couldn’t her but look at her gigantic ass. She had grown to 15 ft.
After gym, Amy told her she had filled it with growth water and thats why Lucy had grown. Lucy laughed thinking it was a joke and Amy told her if she finished of her water she’d outgrow the gym.
They both went in the empty parking lot, Lucy got stuck crawling through the door and Amy had to pusher her giant, soft ass. Lucy finished off the water and started growing again. Soon she was taller than the building and then the sign outside. Amy only reached her heel soon. Lucy was truly gigantic at 25ft tall. Amy called her and Lucy lied down, her giant body stretched across the parking lot and her giant ass that looked like hills.
Amy offered the shrinking water bottle but Lucy said she wanted to stay big for a while. Lucy went to her car and picked it up and walked home. Amy couldn’t wait for the next session.
