In the throes of self-pleasure, a mature man with a sizeable endowment lets loose a primal groan. His hand, slick with pre-cum, glides up and down his engorged shaft, the friction sending electric jolts through his body. His muscles flex, his body glistening with sweat as he chases his release. With a final, intense stroke, he convulses, his cock pulsing as he spills his load. The room fills with the scent of his musk, a testament to his solo indulgence.
