As Sisi Rose packs for her move, she can't help but reminisce about her and stepbrother Peter Green's naughty past. They shared a secret language, a secret touch, and now, one last secret fuck before she leaves. Peter, home from college, catches Sisi caressing her big, natural tits, her panties already damp. He joins her, his cock tenting his shorts. They kiss, fingers entwined, as Sisi strokes his length. She takes him in her mouth, gagging slightly on his thickness. Peter bends her over, slapping her round ass before driving into her, fucking her hard and slow, just like she likes it. Their bodies slap together, sweat mingling, as they chase their climax, whispered promises of future reunions lingering in the air.
