First of all, thank you for continuing the story.
I love the idea "a few women grow huge". When some women grow huge, it connects every idea of you.
To them, the men shrink even more ("same as before, men shrink, women bustier") and to them the women shrink too ("some women shrink").

When they grow, they could be even bustier.

I would love to see when a mature woman grows to a huge giantess and makes everyone her slave or pet. When the mother, the grandmother or a mature neigbor or an old teacher grows so huge, that everyone must do what she says (massage her feet, polish her nails). She could put hundreds of people (man and woman) between her giant breasts.

The society could develeop into an hierarchy, where the bigger ones can do whatever they want to the smaller ones.

It's a great story. I love your themes round about humiliation, tits and power shift.

Please continue your work!

It's hard to suggest an ending, because we just have 8 chapters, but I hope Michelle continues to grow (height and boobs) and she makes her brother her pet or slave. What about Cindy? Will she grow too? Perhaps she can shrink as well and Michelle makes both of them her slaves. Or when Michelle grows to about 7 feet she can dominate Cindy at her current height. Or Cindy and Michelle fell in love and make the brother to their little slave...

Great story!

What about a mature giantess who make him her tit slave? :D
