These two women are sisters. The giantesses is obviously the biggest. They are from different mothers, but this doesn’t mean they are not close. Just the opposite – they are best friends and they are ready to do everything for each other.
The giantess decided that she wants to start a family, but biologically she can’t have children. This was her biggest problem, but at that point her sister came to help. She was ready to give her own child to her sister, so in the end the baby was brought up by his aunt. What a sacrifice… This is what I call a family!
