With no one to watch him but himself, a man dares to indulge in his kinkiest fantasy. He lubes up a sound and carefully inserts it into his pee hole, gasping at the intense sensation. He fucks himself with it, his cock hard and aching, until he can't hold back any longer. With a final thrust, he pulls out the sound, his cum gushing out, painting his body in a mess of his own making.
