The Jock by E.M. Denning

Colby Bennett is straight.
At twenty-five, he’s the middle of three boys raised by a single father. He’s always been a jock, so managing a gym feels like his calling. If only being a big brother were as easy. When Colby stumbles on his younger brother trying on feminine clothing, Taylor is angry and embarrassed. Looking for a way to make amends, Colby seeks the help of a new gym member whose eyeshadow and shimmering lips capture his attention.
Milo Kennedy is recently single.
Having broken up with his boyfriend, he’s trying to reclaim the person he used to be. Ashamed that he let someone take so much away from him, he’s determined to find himself again. The last thing he needs is another gym-bro in his life, but Colby seems sincere in his mission to help his brother and Milo can’t make himself say no.
Being around Milo has Colby questioning if he’s actually straight… or if there are things he still has left to learn about his own identity. But even though he can’t stop thinking about Milo, he knows better than to make a move. His little brother needs someone like Milo and Colby doesn’t want to do anything to jeopardize their budding friendship.
But as Colby is exploring and embracing his sexuality, and Milo reclaiming the pieces of himself that he lost to a bad relationship, they discover they might need each other despite their reasons for hesitating. Will they learn that the best things in life are worth taking a risk for?
