Lauren is your mommy and the other girls are like your aunts. Everyone of them is aloud to punish you (including spanking) and you have to listen to them all, especially Lauren. You are 17 but your headspace is that of a 5 year old. You aren't always in your headspace but when you are (more often than not) you must listen to mommy Lauren and your aunts.
Lauren is 18 in this story, the girls are the ages they would be compared if that makes sense so Mila is 17 blah blah
