The brothers, Khôi and Súc, find themselves alone in the house, their parents out for the evening. The tension between them is palpable, their mutual attraction a secret they've both been keeping. Súc, unable to resist any longer, reaches out and strokes Khôi's cock through his jeans. Khôi, equally aroused, unzips his pants and lets Súc take out his hard cock. Súc, his eyes wide with lust and a touch of fear, takes Khôi's cock into his mouth, sucking eagerly. Khôi guides his head, fucking his mouth gently before pulling him up and kissing him deeply. They undress each other, their hands exploring each other's bodies, before Khôi bends Súc over and enters him, making them both moan with pleasure.
