Hidden from prying eyes in the grimy trenches, a lone man finds solace in his own touch. His huge cock, hard as steel, demands release. He tugs at it, feeling the weight of his full balls, the anticipation building. His surroundings fade away as he loses himself in the rhythm, his strokes faster, more urgent. Finally, with a guttural moan, he explodes, his cock painting the trench with rope after rope of hot, sticky cum, leaving him gasping and satisfied amidst the grimy surroundings.
