Trained By Daddy by Ava Sinclair

When Lila decides to get in shape at the local gym, she fully expects to fade into the background among all the toned and buff women at Excel Fitness. What she doesn’t expect is capturing the attention of gym owner Gabe Hampton. Gabe is huge, buff, and gorgeous. Lila can’t help but think he’d make a great character in one of the naughty books she writes, and it doesn’t help when she learns his nickname is Gym Daddy.
Gabe Hampton instantly takes a liking to Lila. She’s pretty, funny, and kind. The only thing standing in their way is her low self-esteem. He’s eager to break the ice, and the opportunity finally comes when he discovers her writing, complete with a character that reminds him of himself and just the kind of kinky sex he secretly loves.

Will Lila’s fantasies about her own personal gym daddy finally come to life? Gabe Hampton is about to put Lila through the workout of her life and give her everything she deserves.
