The army recruits, all black and hung like horses, find themselves in a private moment, their eyes drawn to each other's crotches. The youngest, his cock tenting his fatigues, breaks the ice, "Anyone ever...?" The others nod, their voices barely above a whisper as they confess their shared fantasies. They undress quickly, their big black cocks standing at attention. The first timers take their time, learning each other's tastes and limits. One by one, they take turns being filled, their moans drowned out by the sound of flesh slapping against flesh. The room is a symphony of grunts and groans, the air thick with the scent of sweat and cum as they fuck each other senseless, their first gay threesome a blur of pleasure and taboo.
