Summer of Sex

The setting for Summer of Sex is a fictitious site called Del Prado on the California coast. After 19 years, a classified government project is closing down at the remote Del Prado site on the California coast. The adults who staff the project are mostly PhD people who confidently expected lifetime employment. They are suddenly scrambling for new jobs in a very tight job market. Most of the people will never see each other again.
After the initial layoffs, only the original employees are left and they have 14 18-year-old teenagers, seven girls and seven boys. Due to the job search angst among the adults, the teenagers are left pretty much without supervision and the kids begin to experiment with sex.
Del Prado is an isolated area on the California coast. It's paradise at the sea shore. However, the bay at Del Prado is filled with sharp rocks and sailing or surfing is not safe. There's little to do but lie on the beach. Del Prado is the site of a government classified project and the entire area is closed to the public. Thus, the teenagers enjoy the ultimate private beach.
The story is told from the viewpoint of Ben, one of the 18-year-olds. Ben is something of a study in contrasts. Ben is a very intelligent boy who stands six feet, eight inches tall, with a 270 pound weight lifter's body. Ben's father is dead and he's the man of his household. However, Ben has a somewhat typical teenage boy outlook on life.
As the last summer art Del Prado starts, two girls compete for the same boy. One of the girls has been the hot babe, teen queen for some time. The other girl is a former fat girl who sculpted her body with a diet and exercise program. The two girls compete for the same teen boy. One of the girls goes topless on the beach to gain an advantage over her rival. Soon, all of the girls are topless at the beach in order to keep their own boy friend. Going topless soon leads to going nude on the beach, again to let a girl keep her boyfriend. Going nude in public leads to sex.
The parents scramble for jobs begins to result in people leaving Del Prado for widely separated destinations.
The teenagers begin to realize that they will very likely never see each again after one last summer of sex at Del Prado.
Initially, the sex is boy friend/girl friend sex, but a couple of instances of girls poaching another girl's boy friend lead to revenge sex.
Soon, all of the boys are involved with all of the girls. Even a few parents get involved.
At first, the sex is just teenagers running wild. However, gradually the teenagers get to know each other, as much a result of the sex as anything else. There are conversation between the teens that go beyond just sex.
Later, even some of the adult women participate in the teens' sexual adventures.
Toward the end, families begin to leave Del Prado as the adults find new jobs. The teenagers, of course, leave with the families. However, the teenagers leave with a certain style. The good byes are centered around final sexual flings with friends who the departing teens will probably never see again, ever. The good byes are something of a measure of how the teens have developed.
The action is fast and furious. Amidst the action, some lessons are learned.
