Robert, left to his own devices in the quiet of his home, allows his horniness to consume him. He starts by slowly rubbing his bulge, feeling his cock throb with anticipation. He peels off his clothes, revealing his muscular body and hard, leaking cock. He lies back on the bed, his hand wrapping around his shaft, stroking slowly at first, then picking up speed. He pictures a lover's mouth around him, their hands caressing his body, their moans echoing in his ears. He feels his orgasm building, his breath hitching, his body tensing. He groans loudly, his cum shooting out, landing on his chest and stomach, marking his solo pleasure.
