A mature, solo explorer discovers the exquisite pleasures of anal fingering, his big, round ass clenching and releasing as he teases his tight, virgin hole. With a generous helping of lube, he tentatively inserts a finger, gasping at the intense, new sensations. As he builds up to three fingers, his breath hitches and his cock throbs, aching for release. The taboo pleasure is too much to bear, and he explodes in a torrent of cum, his asshole pulsing with satisfaction.
