This 4 girls are together because of personal friendship and stuff. Which is nice and adds an extra layer of drama and backstory. I think i remember seeing some photos of them together at Disneyland and at some KTV singing togheter. So is actually true.
There are a few lol moments in this JAV, like when they pee on some guy face, etc. I also found it funny they were tagged as mature woman. Soon they will be doing MILF porn togheter.
