The click of the door closing behind him signals his solitude. He takes a seat in the chair, his gaze fixed on the blank wall before him. His hand, with a mind of its own, reaches into his pants, pulling out his uncut cock. He rolls the foreskin back and forth, reveling in the sensation. His strokes become more urgent, his breath coming in short gasps. He can feel it building, the tension in his body, the heat in his groin. With a final, desperate stroke, he comes, his body convulsing as he releases his load onto the floor.
