In the heart of the jungle, three marines, driven wild by primal urges, cast aside their inhibitions. Their massive, uncut cocks, black as the night, throb with need. They form a circle, each taking a turn to impale himself on the thick, veiny cock of the marine before him. The jungle's dense foliage provides cover as they rut, their bodies slapping together, the scent of sweat and cum mingling with the earthy jungle aroma.
