Alone in his room, Cristiano's mind races with taboo thoughts. He grips his throbbing cock, stroking it feverishly as he envisions his wife sitting on another man's erect shaft. His hand moves faster, his breath hitching as he imagines her moans, her pleasure at the hands of another. Pre-cum beads at his tip, his balls tightening as he nears climax. With a final, desperate stroke, he spills his seed, panting and guilty, yet yearning for more.
