The sergeant's authoritative voice echoes through the barrack, "Line up, newbies! Today, we're expanding your horizons." The recruits, a mix of straight and curious, stand at attention, their eyes widening as the sergeant reveals his intentions. He unzips his fatigues, releasing his rigid cock, and commands, "Suck!" The recruits hesitantly comply, their lips stretching around unfamiliar girth. The sergeant watches, jerking his own meat, as the newbies progress to exploring each other's asses, their fingers tentatively prodding, feeling the heat and tightness. The room becomes a symphony of slurps, moans, and the slap of flesh as the recruits are initiated into the world of gay anal pleasure.
