Downstairs Jeff started hearing her little sister's voice start tattling again and thought about what he should do about that. He put the Chronivac remote in his pocket and going downstairs saw his little sister of 8 years old start telling their mother of 46 about Jeff and his "weird package".
Jeff noticed her mother carrying some groceries and asked "Hey mom you need some help with some of those bags?"
Their mother saw him and said "Sure, could you carry some of the sodas in." Then a few trips back from the car latter their mother asked "So what's this about something weird from your sister?"
Jeff's sister Megan said "Yes mommy he was doing something weird on the internet."
Jeff said "I was just on a forum for people who got this thing which can change things." he fiddled with the switch package targeting Megan and his mother. He then selected their ages and their ages had a few different ways to swap so he decided to go and equalize the two ages. Looking at his mother her slightly wrinkled face and starting to grey hair started smoothing and getting back their color. her breasts once sagging returned to their plumpness from before. Her clothes were a smidge tight around the chest and waist for her but ended up fairly loose around her waist. Jeff said "Wow you were... are a real looker mom."
Then the two heard Megan say in a deeper voice "What the heck happened?!?"

Megan tried covering her chest where her once fitting T-shirt was acting as a horrible tight bra and said "I told you he was doing something weird!"
Their mother said "Jeff you... do something to help your sister." Panicking a little Jeff selected himself and Megan and after some quick math to figure out how old Megan was (8 + 46 = 52, 52 / 2 = 26) then took 16 years from Megan whose body shrank down. No more wonderful curves but still bigger than she was previously and her chest and nipples were slightly starting to exert their presence on her shirt. On the other hand though Jeff went through all his growth spurts ending at a tall 6'2'' and was lightly muscled with his acne having mellowed out and vanished as he was 32. His pants were fairly tight and his shirt was fairly tight.
Megan said "See Something REALLY weird!"
Their mother was just looking and said "Yeah... Funny enough this reminds me of one of the dates your father and I had... Not the whole everyone changing but you do look quite a bit like him Jeff. I do enjoy being younger again, although you should really turn back. having a son older than me is kinda weird you know?" Jeff looked to the chronivac and then...
