The creaking floorboard signals their undoing, but not before Bin's hand wraps around Hậu's throbbing cock, stroking it to full hardness. Hậu gasps, his hands finding their way to Bin's own erection, mirroring his brother's movements. The room fills with their ragged breaths and the wet sounds of their passionate kisses. They're so lost in each other that they don't hear the door open, only the sudden gasp of their mother standing in the doorway, her eyes wide with shock and disgust. Bin and Hậu freeze, their hearts pounding as they realize they've been caught in the most intimate of acts, their secret now laid bare.
