One Night With the Millionaire by Shannyn Schroeder

Over-forty, single mom Tess Howland’s life is all about caring for other people. Indulging in a one night stand is just what she needs. She doesn’t expect to meet anyone she would introduce to her kids, especially not some rich playboy who acts like a big kid himself. Even if he keeps giving her the best sex of her life.
Millionaire Miles Prescott can’t get the sexy nurse he met at a fundraising gala out of his head. For the first time ever, he doesn’t want a woman with no-strings-attached. He wants everything—even it comes with a ready-made family with a woman in her forties. Suddenly, helping with homework doesn’t sound like the worst thing in the world, especially if it means being near Tess.

But what happens when he’s ready to step up and she says no?
