Intro. Your family is for the most part normal, except for the fact that your mom and two older sisters are hung futanaris. Due to this, coupled with the fact that they have raging hormones, they act as nudists most of the time at home. Your dad ran away when you were young after he saw his (then) 11 year old daughters had a bigger dick than he ever had and he ran away before they reach sexual maturity and could fuck him like his wife already does (you share in his fears as well but alas).
