Title: Sin on Wheels [1]
Description: "The first shattering expose of the sex-for-hire Learn-to-Drive schools.  Women with money to pay any fee to satisfy their passion-inflamed lives.  A powerful novel of unleashed desires & men without any moral compunction, feeding on the wealthy hungers of their wealthy, frustrated female students...  The sin-school exposed!"

Fred Bryan, 24, has recently left the army, and while looking for work in New York City, he runs into another man from his unit who is working as a driving instructor at a driving school that is really just a front for a gigolo service.  Fred goes to work for this service and enjoys the attentions of the rich older women whom he also teaches to drive.

The same day he is hired at the driving school, he meets a beautiful girl named Nina in a diner.  She is a painter and a bohemian, and the two of them have sex and start a relationship.  Fred doesn’t tell Nina about the women he has sex with during his day job, since Nina wants an open relationship in which the couple lives as friends who have sex, nothing more.  But the plan changes when Nina confesses that she is pregnant, although the baby is not Fred's.  It turns out she knew she was pregnant when she met him, and the baby is the child of a rich playboy who dumped her.  Nina is prepared to break off her relationship with Fred, but he says that is not necessary since he has fallen in love with her.  He helps her get an illegal, expensive abortion, and says he will quit his gigolo job and marry her.

Complications arrive when one of Fred's client's husband discovers the true nature of her driving lessons, and another client, who wants him for herself, attempts to blackmail him...
