The creaking of the barrack bed accompanies the soldier's frantic wanking, his mind racing with naughty thoughts. He's trying to be quiet, but his breath hitches as he nears the edge.

His body shudders with the force of his orgasm, but he remains silent, not wanting to alert his fellow soldiers to his secret pleasure.
