A fresh-faced, nervous twink joins the army, eyes wide with anticipation and apprehension. In the dimly lit barracks, he's introduced to the raw, carnal side of military life. His drill sergeant, a muscular, experienced veteran, takes him under his wing, showing him the ropes - and the ropes. The twink's slender body trembles as he's ordered to strip, revealing his smooth, untouched skin. The sergeant runs his calloused hands over the recruit's chest, feeling the pounding heart. With a smirk, he unbuckles his belt, revealing his throbbing, eager cock. The twink's eyes widen, but he swallows his nerves, ready to learn the true meaning of discipline.
