Material Girl (1986)

When millionare Howard Clughes goes looking for a house, he has in mind a little hideaway for his chesty mistress. However, Jane Tussell can't seem to keep anything hidden away, and she shows more than the house to prospective buyers. Howard has his eye - and his hands - on Bella, the beautiful assistant of the real estate agent. Harry and Bella are partners in bed as well as business, but they find time for merges with many others along the way.
