The third point of view:
Anabelle was treated to a minute of her parent's "onslaught" and the first thing that came to mind was to cover Alison's eyes. Her sister was too young to be corrupted.
However, when her parents finally ended their passionate kissing and she took off her hands, the grin on Allison's face told Anabelle the girl knew more than she thought. It seems her parent's public display of affection was a daily occurrence.
The next minute was spent with her father Eden trying to woo their mother. With the way their parents were enamored with each other, Anabelle had thought they would have more children, but then, here they are with only Allison.
Anabelle knew it was Camille's doing, she didn't want more children and Eden respected her decision. So romantic! She hoped she and Julie would be as happy as her parents.
