Along Came a Swapper

Along Came a Swapper
by Richard B. Long
1970, Adult Books

Two couples swap partners, eventually leading to a swingers party. I guess Long thought a subplot was needed - one of the husbands talks to his boss every few dozen pages about how it would suck to be industrial espionaged. After the swingers party turns out the entire set up was to blackmail him in an industrial espionage scheme. The wife worries about her reputation so she divorces him and moves in with the blackmailers, while the husband tells his boss, who doesn't care.
