The disciplined soldier's self-control crumbles as he retreats to his quarters, the tight uniform still on, concealing nothing. His massive cock tents the fabric, demanding attention. He unzips, allowing his engorged member to spring free, already glistening with pre-cum. With a grunt, he grips his shaft, his rough, trained hands sliding up and down, his hips moving in rhythm, fucking his own fist. His balls tighten, ready to unleash a torrent of pent-up desire.
