Summer Romance by Orrie Hitt

'What else could she expect at a summer hotel? Behind the scenes at a summer resort where passion is so often mistaken for love!'

Peggy, however, walks the twilight world of secret sex and one night when she and Ruth get drunk and friendly, Peggy seduces Ruth. Now Ruth is confused because she liked having sex with Peggy but does not believe she is a lesbian because she also loves sex with men.
