Jack, dressed in tight jeans and a worn t-shirt, slips into his room, the scent of his sweat already filling the air. He pulls off his clothes, his uncut cock springing free, already half-hard. He sits on the edge of the bed, his hand wrapped around his shaft, slowly stroking. His other hand reaches down, cupping his balls, giving them a gentle squeeze. His pace quickens, his breath hitches, and his face flushes as he nears his climax. With a final, hard tug, he comes, his cum spilling over his hand and onto the floor.
