See You Sometime by Tymber Dalton

Divorced from her Master husband of fifteen years, Skye moves back to Sarasota to live with her parents and rebuild her life. New job, new kinky friends, and she reconnects with her D&D buddies from high school. Including her old boyfriend, Axel. Axel’s been divorced for a couple of years and realizes he’s pretty much given up on dating. He also knows most of his D&D friends are kinky, and they assume he’s a straight-laced guy.

When Skye returns to his life, he doesn’t dare hope there might be a possibility they can make things work now that they’re all grown up. Or can they? Sometimes, the second chance is the sweetest…and the one best able to destroy you. Axel soon realizes if he can’t figure out how to give Skye what she needs, there are plenty of guys who will. But if he has to say good-bye to her a second time, he’s not sure his heart will recover.
