Rachel and Stacie were MILF sisters. Each had a grown son - Brian and Ricky. One summer the four of them went for a month long vacation on a remote tropic island where they had the run of a luxury condo. Also in attendance was Rachel's husband, Frank. Sadly, however, Frank had to go back to the US almost as soon as he arrived. As the head of large corporation he was often called away on important business. Such was the case now. Rachel was none too pleased to see him go. It was a reminder of Frank's workaholic nature and the fact that he so often put his job before her. Their marriage had been void of romance for a long time, and Rachel had been hoping to restore some of it while they were on the island. She wanted to find a place so remote that he would be able to focus on family and forget work for a while. There was something unnatural about this distant island. There were myths of a long forgotten race of people who once inhabited this island. It was said that they practiced strange sexual rituals and that on certain nights you could hear the cries of passion on the wind. So much for that. Yet things were not much better for her sister. Stacie was a divorcee who had not been with a man in several years. Since both siblings were immensely horny, their sex-starved status was almost impossible to endure. But, as it happened, there was relief at near hand - in a highly forbidden form.
