Parents are away by Alphatylon
Summary:

The brother starts shrinking and the sister has fun with it. I am looking for a story where the sister has fun with the brother shrinking but not in an overly violent way.

No vore or death to any of the characters.

If the sister has to go any place then she places her brother inside her underwear. Please let her be hairy down there to make it more interesting like her brother will get tangled up down there. If any feet play get added, have it only for a chapter not something that will continue on for a long time. It would be interesting to have the sister overweight as to be something different from the rest recently.
