Sue noticed that the thing Jill was holding was the gun she had found and tried to get out from under her increasing weight, but sincce now she was 10 and Jill was 13 it wasnt hapening. Jill laughed at her stuggling and just simple said look who is the older sister now. From her vantage point Sue could do nothing but watch, though she had a birds eye veiw of her dear sister's changes as she was naked and so close to her face. she could already see her breasts starting to grow, and she could feel her butt getting larger and slightly wider, but the most humiliating thing was that she had a very close veiw of Jill's new pubic hair just starting to come in, especialy since as she shrank her face was slowly inching closer. As the transfer went on they were now 14 and 9 exactly reverse of before, Sue noticed that Jill was a bit more developed than her at that age, her breasts were B cup already, her butt had a very nice round shape to it and her hips were a good deal more defined, not to mention the fact that she already had a good amount of pubic hair down there too. Sue managed to free one hand to reach up and switch the dial on the gun, she hoped it would help her a bit, but what she witched it to was body hair not to helpfull, but quite a good deal more noticeable on someone who hasnt shaved yet, as Jill didnt notice at first and just drained all the body hair growth Sue took from the jogger as wel as her own natural amount that was laying dormant waiting on her to get old enough to matter again. Jill noticed she wasnt getting any older and checked to gun to find out her sister's change, that would explain why she wasnt getti8ng any younger, but I was still getting more hair she thought. She changed it back, and said so you wanted me to be more hairy sis, well youll regret that in a bit. Sue was already regreting it as now she could see a very womanly bush about twice as thick as a normal one and still growing longer and thicker, as well as a good deal uner her arms and on her legs, she did get a slight bit of a laugh that at least she had made her sister's legs look like a guys, not to mention the long amount of time it would take her to shav eall that. The aging continued as JIll's butt slowly got wider and more womanly, and her breast slowly grew out more and more. She stoped the device at the ages of 18 and 5, Jill now had a Full set of C cup breasts, a nice round butt and wide hips to match. Unluckily for Sue though she had shrunk to the point her face was a mear three inches away from Jill's pussy this fact didnt escape Jill as she said in a much more sultry and womanly tone to her sister that since she made her so much more hairy( and because she was rather horny from the transformation) she could enjoy it for a bit more, and with that Jill started rubbing herself in her sister's face.after humiliating her sister enough that way she told her to stand up in the corner or else shed get more aquainted with her new pussy. She noticed her sister was tall for her age so she stole a bit of her height as well this put Jill at 6 foot 10 and Sue at 2 foot now rather short. The next thing Jill planned on doing was to go take a shower and shave this gross hair off, but then an idea hit her. SHe witched the gun to body hair and let a rip on her sister saying so you wanted me to be more hairy well itll all be yours when your older, when she got back to an average amount of hair growth she stopped and decided to keep that amount as it made her look more adult besides she could easily shave the rest now that it was back to an average amount. She now decided to take the last thing she could from her sister being her brains, she stole almost all of her brains and left her with an IQ of about 47. she then handed the gun to her sister to see if she could still manage to work it, Sue stared at it for a while managed to turn the dial to age after a while not knowing what it means though just luck and fired. Jill aged to 20 and her sister 3 before sue decided that wasnt what she wanted, then she turned the dial to gender and fired, as they were both girls they both felt an od bit of a tingle, but nothing realy changed on Sue, Jill on the other hand slowly changed a tiny bit, her face became more pretty, her bush became much more neat, her hips widened a bit more, her butt took a heart shape, her breasts grew to a D cup as well as became much more firm and gravity defying, and her hair grew much more silky and grew a bit longer. Sue decided to turn the gun around, and switched it to weight and fired. Jill almsot jumped to grab it when she saw her turn it, but then she started loosing a bit of weight she now looked like a super model while her sister looked like a pudgy 3 year old. She then took the gun and hid it on a high shelf in her room and went to take her shower now.
