Female extreme age regression and beautification story

[wissen]

Hi all!

I am looking for a story, where very old grandma (80+ yearss old) became much younger and much more beautiful. So much that she looks as young as her 18 y.o. grandgranddaughter, but much much sexier. It's interesting how her family will deal with it. Especially, grangranddaughter, who gets such unexpected rival in terms of guys.

Thank you in advance!
