When Parents marry for the second time, siblings are brought together. In most cases, that doesn't lead to complications, but when its an open marriage, the rules can change, and the norms can be cast aside. In such circumstances our characters throw aside convention and sex dominate’s family life. There are no barriers except that the rules on incest will apply, but that still leaves all kinds of other options open, trust me, and there is little that our family don't get up too. One of the hottest books I have written. Authors note all characters in this book are 18 years old or older.
