Looking for a line that's a bit of a stretch, but here it goes.
It's futa!step-mother/daughter line, but there are three daughters. The older woman is trying to basically claim all her new daughters and breed them. The older is college age and already pregnant by the parent, the middle one is like 17-18 and is a bit more of a challenge and would be more dub-con while trying to get her pregnant, and the third who is the innocent virgin waiting to be corrupted and is 15-16. I'd play the three girls: (Pb wise I was thinking Amber Heard, Ashley Benson and Indiana Evans). Threading only. Comments screened!
