Private Katerine, alone in the barracks, can't resist the urge to indulge in a private moment of pleasure. With the door locked and the lights dimmed, he strips down to nothing, his hard cock standing at attention. He spits into his hand, lubing up his fingers before pushing one, then two, into his tight asshole. Moaning quietly, he fingers himself, stretching his hole, before pulling out and jerking his cock until he cums all over his stomach.
