Thủy, a rebellious teen with a penchant for the forbidden, finds herself alone with her older cousin, a man of considerable charm and a thick, enticing cock. As they banter back and forth, she can't help but notice the growing bulge in his pants. She playfully teases him, "Anh ra rồi! Em liếm đi," meaning, "You're hard now! Let me lick it." He tries to maintain his composure, but her brazen words and the promise of her skilled mouth prove too much to resist. He gives in, allowing her to unzip his pants and reveal his massive, throbbing cock, ready for her eager, sucking lips.
