Looking at the display you didn't notice anything right away so you turned to her and said "Would you get out of here and mind your own business? Go watch some T.V. or something."
Emily frowned and said "But Jeffy..."
"Out, I dont want you doing anything that would hurt us by flipping the chair or something." Emily frowned a little and sulked off to the family room to watch some T.V. Thinking that you might do something to Emily for almost hurting you both you checked the display again and saw that her age now read 10. That seemed odd, but you thought it was some glitch in the machine. You looked around at all the little different types of changes you could do to Emily and thought that he may age her in certain ways as a small punishment. You thought for a few minutes and then decided that you would inflate Emily's breasts to E-cups for an hour. Your mother was gone and wouldn't be back for 3 so it would work fairly well. When you looked at the stats her age went up to 11 and her breasts had finally gotten to a cups. You inflated your sister's breasts to E-cups and then took a look what was going on with her stats in the advanced stats.
From Emily's perspective she was just watching some cartoons and then after a little while her clothes started to feel a little tight. When she looked her clothes were taught and her nipples were a little pointy and tented her shirt a little. She'd ask for mom to get her some new clothes soon since she was probably just going through a growth spurt. then during the next 12 minutes the flesh under her chest slowly piled under as she was starting to develop through puberty. after the 10 minute mark there was a commerical and she got up and stretched. Her clothes felt even tighter and her chest looked puffed out a little. a little curious she touched her new breasts and found them to be nice and sensitive, out of more curiosity she pinched her right nipple and she moaned from the sharp bit of pleasure it gave the little girl. She was wondering if this was what her mother had meant by changes in the near future as you had just entered the commands for her breasts to grow. underneath her hands her breasts were swelling till they were E-cups. Her shirt couldn't handle the large breasts and ripped open. While large on her she found them to be extremely pleasurable and started to play with them disregarding her broken clothing.
You had found what you thought was the problem. When you slapped the computer's keyboard you had accidentally changed the rate at which Emily aged. Instead of aging a second every second she was aging a month a minute. You thought if you should do anything about this and decided...
