Aboard the Capitan18, Barto, a lonely sailor, retreats to his quarters, his mind filled with carnal thoughts. He strips off his sweat-stained clothes, revealing his toned, tanned body. His hand wraps around his swollen cock, feeling its heat. He strokes it firmly, from base to tip, his other hand cupping his heavy balls, rolling them gently. His mind drifts to forbidden fantasies, his breath hitching as he pictures another sailor's mouth wrapped around his dick. His strokes become urgent, his grip tighter. With a final, guttural moan, he comes hard, his cum splattering onto the deck, a secret testament to his lonely, lustful nights at sea.
