In the barracks, a Marine drill sergeant, a burly black man, commands two young, eager recruits to "stand at attention" - and they do, but not in the way he expects. The sergeant, a dominant top, strips down to his uniform pants, revealing his massive, hardening cock. The recruits, equally endowed, follow suit, their thick cocks bouncing free. The sergeant orders them to service each other, and they comply, hungrily sucking and stroking each other's dicks. The sergeant then commands them to fuck, and they do, switching positions, their tight, muscled asses slapping against each other as they grunt and groan in pleasure. The sergeant, unable to hold back, joins in, fucking one recruit while the other watches, jerking off, before all three collapse in a sweaty, spent heap.
