The humid night air of Saigon fuels his desires as he creeps into his brother's room, drawn by the heavy scent of sweat and sex. He finds him asleep, his cock tenting the thin sheet. He can't help but lean in, pressing his face against his brother's crotch, inhaling deeply. His own cock hardens, straining against his pants as he pulls down the sheet, revealing his brother's thick, uncut cock. He takes it into his mouth, swirling his tongue around the head, tasting the salty pre-cum that's already leaking out. His brother moans in his sleep, pushing his hips up, fucking his mouth as he sleeps.
