Michelle's confession spills out in a rush of guilty pleasure. She's been fantasizing about her brother's huge cock, dreaming of it stretching her tight pussy. She can't resist any longer, pushing him onto the bed and straddling him. He's hesitant at first, but as she grinds her hips, his cock hardens, and he starts to thrust up into her. They fuck passionately, their bodies slapping together, until they both come undone, collapsing in a sweaty, satisfied heap.
