Mark and Alistair think they’re happy with their open relationship—they can have all the anonymous sex they want, and still come home to each other for love and affection. That changes when they discover that they’ve both hooked up with the same guy, and, worse, that they’re both falling for him. Tyler is a take-it-as-it-comes type, happy to coast through life on his good looks and charm. He doesn’t have ambitions and doesn’t make plans, but when he finds himself involved with Mark and then Alistair, he starts wishing that he could have something more long-term. Nobody has any doubt that sex between the three of them would be fantastic, considering how hot things are when there’s only two involved. But can they make it something more? Is the threesome destined to be a scorching memory, or can they find a way to overcome their challenges and hit the trifecta?
