The old man, alone and unseen, presents a taboo spectacle. His gnarled, weathered hands grasp his sturdy, aged cock, veined and thick with years of unspent lust. He strokes it with a familiar rhythm, his face contorted in a mix of pleasure and guilt. The room is dim, the air heavy with the scent of his body and the sound of his hand moving over his flesh, a symphony of forbidden desire.
