The Cursed Dragon’s Untouched Mate by Silvana Falcon

Never been touched, never been kissed — until Kieran enters the picture.
Being one of the last regular mortals left in the world, Cale has spent most of his life in hiding and in isolation. Out in the woods, there weren’t a lot of opportunities for him to experiment or gather experience. Now that he’s back among people, though, he plans to change things.
As luck would have it, fate leads him to a gorgeous storm dragon shifter, and Cale can hardly believe it when the handsome stranger leans in close and shamelessly flirts with him.
Cale wants Kieran, but Kieran is keeping a secret — he’s been cursed, and anyone he loves will get hurt.
