Olivia's slender body writhes to the birds' symphony, her fingers dancing over her wet folds, teasing her clit. Her mind fills with fantasies of her brother joining her, of him stripping off his clothes to reveal his massive, throbbing cock. She'd stroke him, feeling his length pulse in her hand, before taking him into her mouth, tasting his pre-cum. She'd ride him, feeling him stretch her tight pussy, his hands gripping her small tits, his hips slapping against her perfect ass. The birds sing on, oblivious to Olivia's taboo desires, as she brings herself to the edge, her body tensing, ready to explode in a climax that echoes the beauty of the natural world around her.
