Moving In! (1986)

An outrageous interracial couple (Lili Marlene and F.M. Bradley) moves in next door and introduce themselves into the normal lives of Chuck and Sonia Rollins (Ron Jeremy and Stacey Donovan) and infect them with the spirit of proper modern suburbia swinging. After receiving a gift-wrapped woman as a present, Sonia and Chuck realize how their newfound friends of the flesh have opened the raunchy horizons of their sex lives.
