My Mom Turned into a Little Girl

I'm 24, unemployed, and my parents divorced. I went with my dad, but then he got divorced, remarried, divorced again, and remarried again. His latest wife, a yellow-haired girl, divorced him at lightning speed, and then I was taken home by a girl who looked like she hadn't even been weaned yet. She's 21, has the mind of a child, and is my new mother in the eyes of the law.
