Four muscular, uniform-clad Marines, horny and eager, gather in the gas chamber for a different kind of initiation. Their hands roam, unzipping flys and releasing throbbing cocks, as they explore each other's mouths and asses. One Marine, on his knees, takes three thick cocks at once, gagging as they fuck his face. Another leans against the wall, legs spread, as a fellow Marine rims and fingers his hole before sliding in, fucking him hard while he sucks off their comrades.
