Give her back some of her youth and beauty!

"Oh David! That's delightful!" Your mom runs, or well walks on her bad knee, toward you for a hug. "I know I'm not much fun these days since I've gotten older, but surely there's something we can do together." She says, a small frown forming on her face. You take notice of it.

"How about we go on a walk or go to the theme park, like when I was a kid!" You respond, trying to get some nostalgic energy flowing through those old bones.

"David, you know I would love to, but...", she points to her knee, "I'm afraid all that walking would do me in dear!"

Your mom has always been last to consider herself for any joy or pleasure. You can tell she feels she'll just be a burden to you, either because she's boring or because she's just too frail. Well, one of those is an easy fix...

"My mom will suddenly become 20 years younger."

Their is a slight 'wooshing' sound, as time unwinds the damage done to your mother. The first thing she notices is her knee feels better. "Oh Davy, on second thought...maybe I can manage all the walking. You know what, let's go! It'll be just like old times!" While she says that, you notice her wrinkles smoothing out, her body going back to a time before your father passed, a time when she took great care of her appearance.

As wrinkles face, her skin tightens somewhat, and varicose veins recede from sight. Her boobs firm up quite a bit; an effect you hadn't considered when you changed her. When she was this age before, you were 5 years old. You were aware of boobs, and probably had the same fascination any little boy has...but you didn't have any sexual thoughts associated with them.

Now though, you had to admit, your mom was hotter than your childhood memories had let on.
