Amy had a clear view of the entire store from Lina's shoulder, but it was taking some time to point out a small banzai tree. Fortunately she was able to see the front of the store to get her bearings. Lina covered the distance quickly, and after just a few minutes they were closing in on where they had left the eraser. Lina was growing all the while, and Amy was glad her boots were magically enchanted to fit its wearer, no matter how she changed.
"I see it!" Amy said. "Up this aisle!"
"Uhn...Amy, hang on..." Lina suddenly bent over, and Amy had to use quick reflexes to jump off her and grab onto a nearby shelf. She started to climb down to the floor.
"What is it?" she asked.
Lina was doubled over in pain. Amy could hear the sounds of tearing, and watched as her body completely tore off her already ripped shirt. Her flat chest was revealed. Only two small nipples remained of the inheritance she had passed to Amy. Lina continued to groan, moaning "Hurts!" and fumbling to pull off her shorts. Amy didn't want to look, but the unreal sight was something she just couldn't stop watching. Lina's thighs obliterated the denim shorts as her waist split them on the inseam. Without the shorts to hide them, Amy discovered the true source of Lina's discomfort: Her underwear was so tight it was threatening to slice her privates like a choke wire.
She wished she could help, but didn't dare go near the growing girl's flailing legs, which looked big enough to kick her across the store. After an agonizing eternity, Lina finally snapped off the panties, which now resembled a g-string, eliciting a moan of pleasure and relief. She panted for a minute, sitting on the floor. Amy couldn't believe what she had just witnessed...and the fact that even when she was sitting she was still more than twice as tall as her.
"Sorry..." Lina wheezed. "That was just...really bad."
"It's okay," Amy said shyly. She didn't want to admit that the ordeal had provoked a disturbing emotion in her. "Are you all right now?"
"Yeah," Lina replied wearily, picking herself up. She lifted her left arm to straighten her hair. "Let's get go--" Her voice cut out after hearing Amy scream. She felt the tug at her left wrist and realized that she had just lifted Amy off the ground. She was desperately clutching her collar, dangling around Lina's knees and making frightened gurgling sounds. "Oh jeez!" Lina quickly dropped her arm and Amy landed on her boots. "I'm sorry!"
Amy forgave her, but suggested she continue to carry her on her shoulder for safety. Lina agreed.
Now back on course, Lina walked up to where the eraser sat on the highest shelf, not nearly a problem to reach for someone of Lina's stature. Before they knew it, the collar was off, but the damage was done. Lina took another round of measurements and determined that Amy had lost an entire foot, down to just one-foot-ten, and Lina was even larger at a solid nine feet.
At Amy's request, Lina carried her back to the large book, placing her on the counter right next to it. "PLEASE be more careful this time!" Lina urged before walking back to the clothing section.
