Peter Green's eyes widen as he catches Annabel Redd, his red-haired stepsister, massaging her big ass and fingering herself in their shared bathroom. Her skin flushes with lust, contrasting against her fiery hair. She moans softly, unaware of his presence. Peter's cock hardens, tenting his shorts. Annabel notices him, gasps, but doesn't stop. She offers him a sultry smile, inviting him to join her in their taboo dance.
