In the dimly lit room, young Kevin eagerly unzips his jeans, revealing a colossal, throbbing black cock that tents his boxers. His hands tremble with anticipation as he grips the thick shaft, stroking it gently. His eyes roll back in his head as he feels the massive vein pulse against his palm. He can't help but moan, his grip tightening as he picks up speed, his hand a blur as it races up and down the engorged length. The room fills with the sound of his hand slapping against his cock, his breath coming in ragged gasps as he nears the edge.
