The brother, Bach-Tung, is a man of few words, but his body language speaks volumes as he steps out of the shower, water cascading down his muscular form. His sister, Chu, can't help but admire his physique, her eyes lingering on his hardening cock. She bites her lip, her heart pounding in her chest as she takes a step closer, her voice barely a whisper, "Là Lại Cũng Đi, Anh." (Let's Go Too, Brother.) They stand there, their bodies inches apart, the air thick with tension and forbidden desire, ready to give in to their carnal urges.
