The army dude, a jock with a big dick, can't resist the temptation of some solo fun. He locks the door, strips naked, and settles into a comfortable chair, his hard cock standing at attention. He starts slow, teasing his foreskin, running his thumb over the sensitive head. His strokes gain speed and intensity, his breath hitching as he nears his peak. With a grunt, he comes undone, his cock pulsing as it spills his load onto the floor, leaving him grinning, his body relaxed and content.
