Three fit, uniformed marine men, new to gay encounters, explore each other's bodies in a tense but titillating session. The straight-looking one watches as two of his comrades suck each other's nipples, their hands tentatively exploring each other's cocks. The tension builds as they stroke and lick, their uniforms becoming increasingly disheveled. The straight marine can't help but join in, feeling his own cock harden as he watches his fellow marines indulge in their first gay experiences.
