Lock and Key Volume 1 (Paperback, New edition)

Entwined Dreams: Book One Rejected. Heartbroken. Devastated. Zack Davis wanted to serve only one man, Andrew Nikeman. He was denied because Andrew thought he was too young and because their brothers were together. So Zack crushed his submissive tendencies and focused on being the perfect Dom, giving every sub he played with something he couldn't have.  After years of denying his submissive side, Entwined's charity auction "Are you Dom Enough to be a sub?" gives Zack an excuse to get a little of what he's always craved. Andrew doesn't know when his infatuation turned into more, but it kills him to see Zack with a constant parade of submissives. He'd refused to jeopardize his brother's relationship or become Zack's regret; however, Zack isn't a kid anymore, and his brother's relationship is unbreakable. Now Zack's popularity and success as a Dom might ruin Andrew's dreams of collaring him, but he can't wait any longer to confess his feelings or he risks losing the man he loves forever.
