Just Your Body, Baby by Bart Michaels

'Nude models. They're the girls who don't mind displaying their glorious bodies to artists and photographers.... But they're not all alike. Some of them - like Gale - don't really like men. They like other women better....Some - like Louise - like men and women.... or combinations of both....They all try to claw their way ruthlessly to the top, and some - like Vera - succeed... no matter what it costs them...And when a man like Eric gets in the middle, anything can happen.'
