Duncan Saint, the strapping stepbrother, catches Slay Savage, his busty stepsister, masturbating in her room. Instead of backing out, he joins her, his massive cock hardening as she watch. Slay, hungry for his thick length, takes him in her mouth, expertly working his shaft with her tongue and hands. Duncan returns the favor, spreading her legs to feast on her wet pussy. He slides in from behind, gripping her hips as she moans, taking his cock deep. Slay bounces on him, riding him hard until they both climax in a sweaty, breathless mess.
