husband make her wife sleeping with powerful man to reach her goals

i watched this movie Indecent Proposal (1993) talking about

A millionaire offers $1,000,000 to a young married couple for a night with the wife.

and i want to know if there any other movies like that for wife and husband boss our rich friend our political/army member
not cheating just a husband who use her wife

This only counts as 'sort of'. They're not married, but in Deadly Dreams (1988) a man (Xander Berkeley) sets up his brother (for some kind of gain I can't remember) with his girlfriend pretending to be a complete stranger.
