Cole thought the bachelor party would be harmless. After nearly ten years together, he knows Ryan better than anyone. His handsome, outgoing fiancé can flirt, drink, and enjoy one last wild weekend in Las Vegas before their wedding.

At least, that was the idea. Then Ryan meets Marcus. Older. Confident. Successful. And completely unbothered by the fact that Ryan is getting married in a few days.

What begins with a photograph from a casino bar becomes a series of increasingly dangerous messages.

Met someone interesting.

He knows I'm getting married.

And finally: Can I kiss him?

Cole should say no. Instead, staring at his phone hundreds of miles away, he gives Ryan permission.

It is supposed to be one night. One mistake before the wedding. One secret fantasy that will end when Ryan comes home. But Ryan and Cole still get married. And Marcus doesn't disappear.

When a message arrives weeks later saying Marcus is back in town, Cole is forced to confront the truth: watching another man want his husband awakened something in him that jealousy alone cannot explain.

Soon, the fantasy that began in a Las Vegas hotel room follows them into their marriage, their home, and eventually their hearts.

Three men. Two husbands. And a relationship none of them planned.

The Bachelor Party is a provocative gay erotic relationship drama about jealousy, permission, husband sharing, voyeurism, temptation, and the dangerous possibility that opening a marriage might create something none of them are willing to lose.

Cole thought the wedding would close the door. He had no idea the bachelor party was only the beginning.
