Hudson by Lara Norman

It never occurred to him that accepting help from a good Samaritan would end up threatening his job.
Hudson Clark is driving to a new town and can’t believe his bad luck when he blows a tire in a heavy storm. Thinking he’ll be stuck for the night, he’s extremely grateful when a young woman offers him a ride.
What he doesn’t know is that Reagan Hughes wants to start her new life as something other than the same old goody-two-shoes virgin. When Hudson can’t find an open tow company, he becomes the target of her plan to fix her dilemma.
He would never have expected what came next.
The next time they run into each other is a day neither will forget. Reagan’s new professor is her naughty one-night-stand, and their attraction for each other is forbidden. What’s a girl to do when what she craves is taboo?
