In a private, sunlit room, a man struggles with his gay desires, his wife's thong ("calcinha") a constant temptation. He tentatively strokes his cock, his mind filled with taboo images. He pictures her wearing it, her curves accentuated, her scent lingering. His strokes quicken, his breath ragged, as he envisions her catching him, her surprise turning to desire. With a guttural moan, he comes, his cum mingling with her arousal on the thong, a secret shared only by the fabric and his guilty pleasure.
