As it turned out, the worst didn't happen. His giant blonde sister shrugged far above and closed the cap. She paused to stare down at the pile of clothes by the bed and looked around in curiosity. She couldn't have imagined that her teensy brother was staring up at her from far below completely nude and trying not to fantasize about his own sister.
Max heard a heavy sigh above and watched as Mandy shook her head in apparent embarrassment. "Man, look at me... going through little bro's stuff."
Mandy turned to leave the room. Even as Max breathed a tiny sigh of relief, though, he was suddenly startled as Mandy looked down directly under his bed... and completely missed him. She left his room and clicked the door shut.
“Thank fuck.” Max said in his high pitched voice. He began laughing hysterically in relief and leaned back against the bed.
He let himself fantasize again, he replayed the image of his giant sister towering like a goddess. He tried not to make his fantasy his sister. Maybe some other girl. Yeah, yeah, a huge girl using him while shrunken.
That thought titillated the young teen as much as the idea of shrinking a woman himself.
He started masturbating again and felt warmth and excitement coursing through him as he let his size changing fantasies run wild. He imagined himself small enough to slip under doors and into bank vaults. He imagined shrinking his beautiful Asian teacher little by little. He imagined having a harem of tiny girls to play with and pleasure him.
He came quickly, squirting off with a tiny moan so hard that his first shot hit his chin. After a particularly wet and sticky orgasm, Max wiped himself off panting and climbed out from under the bed. He realized that he still had a lot of time before he would grow back to normal size.
Perhaps he could have a little adventure!
