Greg Smith, the curious stepbrother, finds himself in the unenviable position of sharing a bathroom with Adalina, his stepsister with a penchant for public pleasures. As he relieves himself, he hears the unmistakable sounds of pleasure coming from Adalina's end. He peeks through the gap in the door, his mouth agape at the sight of Adalina's head bobbing up and down, her lips stretched around her girlfriend's thick shaft. The room fills with the wet sounds of their lust, the scent of sex heavy in the air as Greg watches, his own cock straining against his pants.
