In the dimly lit room, the stepfather's voice booms, "You two, on the bed." The virgin teens, brother and sister, exchange nervous glances. As they lie down, their father orders, "Fuck each other hard. I want to see you both come." The brother hesitates, but the sister, her pussy already wet, guides his cock to her entrance. He penetrates her roughly, her tight pussy stretching to accommodate his size. They fuck furiously, their bodies slapping together, until they both climax, their cries of pleasure filling the room.
