A Love Unbound is about a deep, loving relationship between people who see nothing wrong with fulfilling their sexual fantasies, even when those fantasies involve others.
Lyn and Tony are former lovers who meet by chance and decide to pick up where they had left off twelve years earlier.
Whether they were together or having phone sex, nothing was off-limits. They even discussed some sexual fantasies that neither of them had ever mentioned to anyone else. Since some of those fantasies included sex with multiple partners, they agreed to try them, if only for the additional excitement!
