Cheryl pressed the older button and viewed the instructions that popped up on the small LCD screen.
~Type in Desired Age~
Cheryl thought a minute.
'Man, it would be awesome to see what I look like when I get as old as my sister.'
Her sister, Tiffany, was 16 years old versus Cheryl's 13. Tiffany was attractive and was fortunate enough to inherit the genes that grew to large boobs. Cheryl knew her sister wore a 32C from folding laundry.
Cheryl looked at her own 30A's and wondered if they would be that large when she was 16. Only one way to find out.
She typed 16 into the remote, pointed it at herself, and pressed play.
As soon as the beam hit her, Cheryl knew things were happening. Her body felt warm and began to tingle. Her heart rate increased and her breathing became labored.
She noticed her hands had become more slender and her nails grew stronger and longer. Her hair became thicker and longer. It also lightened from its original brown to a dirty blond. Her clothes started to get too small as she grew four inches taller. Her hips spread and her ass filled out, requiring her to unbutton her jeans to make room. Her face became more defined and attractive.
Finally, she noticed her bra felt small. She saw that her nipples were tenting her shirt as her small mounds increased in size. Her bra came unclasped allowing her expanding breasts to grow unrestrained. Her t-shirt, which girls always seem to wear tight, grew tighter. It was easy to see her boobs as her shirt contoured to their shape. As her chest expanded, her shirt grew ever more constricting.
Cheryl became more excited as they definitely passed through the B range and entered into her sisters C range. They continued to grow briefly before they slowed and stopped.
Wow, they looked tremendous looking down at them from up top. Cheryl wasn't sure how big they were since she had only seen her sister's boobs from the 3rd person point of view. Now that she was in 1st person view, they looked huge. There was one way to find out if they were as big as Tiff's.
Cheryl took off her small jeans and looked at her hips and ass. Her panties were a little tight, but she didn't want to take those off since her family was still in the house and might catch her. She then walked to her sister's room with an exaggerated sway in her hips caused by their further widening.
She went into Tiff's room and shut the door. Tiff was out at a friends that evening. Cheryl then opened the dresser drawer and pulled out one of Tiff's bras. She set it on the bed and then began to take her shirt off. This was harder than usual because it was so tight. After finally lifting it up over her boobs, she was able to slide it over her head. It was definitely stretched out a bit, but that was alright.
Cheryl grabbed the bra and, not yet being a pro at the bra clasp, put it on around her mid section so she would not have to bring her arms up so high on her back. She then slid the bra up, and pausing to put her arms through the straps, brought the cups up to her large breasts. What she saw surprised her.
The bra fit! Almost. Her boobs bulged a bit. She was a cup size too large. This was fantastic! She was a 32D. She decided also to try on a pair of her sister's panties. These seemed to fit well. Even though the bottom portion of her hourglass figure was quite curvy, her sister was just as large in that department as Cheryl now was. Just at the pinnacle of her excitement, disaster loomed its ugly head.
