Leela remembered how much greater her pleasure was once she grew from 100 feet to 500 feet. She wondered if being bigger made her more pleasurable. So, she decided to point the growth ray at herself, and pull the trigger. She already knew that she was right, because the second she grew, she was filled with ecstasy, wanting to grope herself as she grew, as her ass became too wide for the street, overlapping the sidewalk, and knocking over the buildings beside her. She screamed with orgasmic pleasure, as she felt thousands of tiny, little, insignificant bugs get crushed underneath her ass.
Leela stopped at a height of one mile, sweating and panting from the orgasmic rush of her growth. Leela felt like she needed to pleasure herself, NOW! She laid on her back, crushing even more buildings and people, grabbed the nearest, narrowest, tallest building she could grab, and started to shove it in and out of her pussy. Every second, she would increase the speed of her masterbation, moaning even louder, sweating even harder, eventually getting to the point where she was repeatedly raising her pelvis in the air, and slamming it back down to the ground, making an even deeper crater the shape of her ass, until she climaxed, spewing out gallons of cum, flooding the street in front of her.
She settled down, throwing the building she used as a dildo all the way across the city. After a while of catching her breath, she sat back up, and looked around, remembering what she was doing.
"But first-" she said, as she pointed the growth ray at her boobs, enlarging them until they were the size of watermelons (at least to her, they were). "Much better," Leela said with a lustful grin on her face. "Now what?" She asked herself.
