Sex After Sixty: Book One: The Art of Sex Rediscovered

Jan and Del Summers retired and decided to downsize to a retirement community. She was asked to join an arts group and when she came home from her first meeting, she took Del right to bed for their most lusty sex in years. She told him they had a male nude model and how it all got pretty loose and now he had a wife who was wildly insatiable in bed. And soon after, they all began swapping husbands as things went further and further. You'll want to come along and see for yourself.
