A househusband for her. A loving couple with a shifted dynamic - she works as a CEO and he's the "trophy wife." Pegging and other toys, light cross dressing (she'll want to see her man in cute lingerie and heels after a long day at work), and plenty of opportunity for other kinks.
Alternately, I wouldn't be against a young man (17/18) that she could groom into her beloved plaything.
