The sun sets on a punishing day of military training, and the new recruits are brought to a secret location for their final lesson. The drill sergeant, an insatiable gay man, has other plans than just teaching them about weapons and tactics. He gathers the straight recruits around, his eyes gleaming with anticipation. One by one, they take turns exploring each other's bodies, their hesitant touches progressively becoming hungry, desperate gropes. The sergeant guides them, his voice gruff with desire, as they learn to appreciate the pleasures of gay sex in a raw, outdoor threesome.
