As I continued to ravish her, her moans grew louder, her body writhing in ecstasy with each powerful thrust. The climax of our passionate encounter left her completely spent, her body trembling with the overwhelming sensation of pleasure. The sight of her glistening with my hot release was enough to bring me to the brink of ecstasy, marking the end of our unforgettable encounter.
