I straightened my dress and waved at Trevor as his car pulled away. My legs were like jelly from the explosive orgasm I had just endured as I tottered...toward my house. My pussy was still tingling as I walked tentatively up my driveway.I placed my key in the front door and entered my marital home. Robert was standing in the kitchen doorway as I moved toward him.
