In a dimly lit room, two brothers, one gay, the other curious, exchange nervous glances as they prepare for their private lesson. Their tutor, a seasoned pornographer, guides them through the art of deep-throating, his voice steady and reassuring. The room fills with the sound of wet, sloppy sucking as the brothers eagerly explore each other's massive cocks. The gay brother, hung like a horse, teaches his straight sibling how to take every inch, while the tutor watches, his own cock straining against his pants.
