A cruise in the Pacific goes all wrong, the ship sinks, and there were only 3 survivors; Damian, Darren and Deirdre. They manage to swim to a small island and they lived there for a couple of years doing what's natural for men and women to do.....
After several years of constant casual sex, Deirdre felt absolutely horrible about what she had been doing. She felt that having sex with both Damian and Darren was so bad that she killed herself.
It was a very tragic time but Damian and Darren managed to get through it and, after a while, nature once more took its inevitable course...
Well, a couple more years went by and Damian and Darren began to feel absolutely horrible about what they were doing.............
So they buried her.
