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!
