In a monochromatic world, a lone man indulges in his darkest desires. The room is filled with the sound of his heavy breaths and the wet slapping of his hand against his thick, veiny cock. He pauses to slick up his fingers, then reaches around to tease his tight, puckered asshole. Slowly, he pushes a finger in, gasping at the intense pleasure. He adds another, stretching himself wider, and begins to fuck his ass in earnest. His body responds, his cock leaking pre-cum as he works his hole, lost in the moment, completely absorbed in the taboo pleasure of solo bum play.
