I'm looking for a story about a couple that go to a Caribbean island I believe. When they arrive they see women dancing provacitively on the beach. The women are basically helpless slaves that people can have sex with. I believe men could just claim lone women to be their slaves. Eventually the woman who came to the island is taken as a slave, her boyfriend searches for her but eventually moves on. She becomes one of the women dancing on the beach but he doesn't recognize her as he walks by on his way to the boat to leave the island.
Don't know if that sounds familiar to anyone from the information I can remember. I'm not sure if I saw it on this site, or of stories, possibly Literotica as well. Thanks for why help you can provide.
