I was serving my wife, her boss, and several important clients of theirs at a dinner party at our house. I was in the kitchen preparing desert when I felt his hands grab my hips. With a deft and quick move her boss slid my panties down my thighs and entered me, as he had done many times before. All with my wife's blessing.
For the rest of the evening, I realized, I would be reminded of his claiming me by the wet leaking of his sperm into my panties.
