Simon decided to go ahead and make everything better.
First, he made mom a widow - setting a 'husband dead' memory dated ten years ago - and selected 'private income' under 'social/economic' so she wouldn't have to work. Then he set 'Jane' to 4'6" - his sister's height - but kept her measurements the same. This made her 34B tits look gigantic.
Then he increased his mother's libido and took the virgin/preadolescent lock setting off his sister's libido. He also gave them both incest fetishes and low sexual self-control. And for the crowning touch he gave them both cocks and bisexuality.
Now Simon polished it up - he made his mother look ten years younger and made his family nudists.
Removing 'Jane's' narcolepsy, he took her out into the kitchen, where his mom and sister were putting away groceries.
