Three strapping gay soldiers, under the guise of a routine medical check-up, strip down to nothing in the open-air tent. The sun beats down as they take each other's temperatures, feeling pulses that quicken with lust. One medic, kneeling, takes two rigid cocks in his hands, stroking them in sync. Another leans over, hungry for a taste, his tongue flicking out to lick pre-cum from the tip. The third, standing, grips his own throbbing member, jerking it eagerly as he watches his comrades suck and fuck each other under the vast blue sky.
