To Love, Honor and Share by Zoey Sparks

Luca’s the wildest man I’ve ever met, and his swingers’ parties are legendary. His plans were simple: visit Australia for six months, then leave. But that was before he met Dylan and I. Now that he’s shown us how wild life can be, we don’t want him to go – but his visa’s about to end and the only way he can apply for another one is to get married.
To me.
We stage a fake wedding, but with his immigration officer constantly sniffing around, we’ll need to do a lot more than that before she’ll let him stay.
And there’s a catch… to be eligible for the visa, our relationship has to be monogamous. And not only am I also with Dylan, but I’m falling for Luca and his hot-yet-nerdy immigration lawyer, Corey, too!
