Under the open sky, a rugged marine, his uniform unbuttoned, reveals his throbbing, uncut black cock to his straight buddy. The new recruit's eyes widen, but curiosity and desire override his initial hesitation. He tentatively touches the massive dick, feeling its heat and weight. The marine takes control, guiding the straight guy's hand in a slow, rhythmic jerk. They move to a secluded spot, the marine pushing his buddy down onto all fours. He spits on the tight, virgin ass, rubbing the saliva in with his thick cockhead. The straight guy gasps as the marine slowly eases in, filling him completely.
