Walking my wife into a room lit only by firelight, with ten or so men and women - all strangers - with her wearing a blindfold and dressed in an elegant cocktail dress, stockings and stilleto heels. Then, with her standing in the centre of the room, I unzip her dress and allow it to slide from her body, revealing her glorious nakedness. And then I step away from her, effectively giving her to these people, so that they might pleasure themselves with her, and at the same time, pleasure her to her capacity.
Typing that out has definitely warmed me up at my desk.
