Two weeks at a five-star luxury resort on the Ninh Van Bay was just what Graham and Sadie needed to escape the brutal Minnesota winter.

When the first days of their vacation are spent indoors to escape the torrential rain, they engage in bedroom activities. But soon a line of dirty talk ushers a startling confession.

Graham's fire is stoked.

What Sadie told him won't leave his thoughts. How could she be like that? That's the way his wife was?

But he wasn't mad. Quite the opposite.

He was intrigued. Riled up. He wanted to know more. What she told him brings them closer, but it's changing how he sees her.

After a night of pool and drinks while the rain falls outside the resort's bar, a wager is made.

The stakes are high, but Sadie is competitive.

Would she ever dare to do the thing Graham wants?
