In a cramped Vietnamese apartment, siblings Ka and Linh Ka, left alone, find themselves drawn to each other's bodies. Ka, the older sister, notices Linh Ka's growing bulge as he watches her dress. She teasingly asks, "Whatcha got there, little brother?" Before he can respond, she pushes him onto the bed, straddling him. Linh Ka's hands roam her curves, cupping her breasts through her thin blouse. Ka grinds against him, feeling his hardness. "You like this, don't you?" she whispers. Linh Ka, unable to control his lust, admits, "Yes, Ka. I want you."
