The Virgin Rule Book by Lauren Blakely

A sexy, brother's best friend sports romance from # 1 New York Times bestseller Lauren Blakely! Let me make a few things clear. I didn’t go to the wedding intending to dance with the best man, to dare him to show me a very sexy pic on his phone, or to accidentally kiss him in the hotel elevator after the reception ended. But things just happen at weddings... The next day, Crosby and I agree to put all those shenanigans behind us. The fun-loving, stupidly gorgeous, all-star baseball player might be my brother’s best friend, but he’s my good friend too and has been for years. I can't risk losing him even though now I can't stop thinking about how much I want him to be my first. After he takes me to a gala, I make him a proposition. A few nights of friends with benefits, and the benefits are lots and lots of Os. The biggest rule of all? We walk away friends. But the more nights we spend together, the more I start to feel for my friend. What will happen to our friendship if we rip up the rulebook?
