Save The Date by Annabeth Albert

Randall Young has one duty as his sister’s “man of honor”: to ensure she has the best wedding ever. That includes an epic bachelorette pub crawl, leading him to Portland’s most popular gay bar… and into Hunter Mitchell’s well-muscled arms.

Publisher Description

A one-night stand with a sexy soldier is the perfect way to ditch that pesky V-card and get himself in the mood for a weekend of flowers, cake, and nuptials.

Hunter wants to blow off some steam before he stands up as his best friend’s best man. He’s already married to his military career, not looking to settle down. He certainly doesn’t intend for the one guy he met (and, okay, got off with) in Oregon to be his counterpart in the wedding party. Or a virgin. Definitely wasn’t intending that. Luckily, they have the rest of the weekend for Hunter to show Randall what he’s been missing.
