Oh shit! It was Mandy! His high school senior sister. Max blushed deep red and froze in mid-stroke at the thuds of his giant sister's feet passing by. She seemingly thundered by in slow motion.
"Max?" She called. The noise pounded above as his tall blonde sis called for him.
With no response, the older teen shrugged. Max scurried to the edge of his bed and laid low, lying on his belly and staring up at his terrifyingly huge sister. From his scale, she looked like a titanic goddess. He traced up her long trunk-like legs and past the huge swells of her big breasts. They were two giant hills to Max and the contours under her tight shirt were suddenly the sexiest thing he had ever seen. Imagine how big she was to him now!
He blinked in alarm as he realized she was turning him on even more than he already was.
"Hey..." He heard Mandy whisper. "What's this?"
Oh shit! Oh shit! Oh shit! Even before he saw her pick up the vial he knew what she was looking at. It was so out of place in his room that of course it would draw attention.
"Cool!" Mandy held up the expertly crafted glass, examining the vial and sloshing the green liquid inside around. "It's supposed to be a magic potion! You would like nerdy stuff like this, Maxy."
"Oh, Mandy..." Max winced, barely whispering in his super high pitch as he watched in horror. "Don't do it! Don't!"
To his mounting disbelief, his giant sister twisted off the cap of the vial and took a deep sniff.
"Mmm!" She smiled at the pleasing aroma. "Smells good!"
No no no! Don't do it! Two inch Max suddenly debated trying to get his giant sister's attention. He also realized he was butt naked with a tiny throbbing boner.
