Richie Black's eyes widen as he catches Emma Stoned, his stepsister, pleasuring herself in the bathroom. Her tight body glistens with sweat, her fingers buried deep within her wet pussy. Driven by primal instinct, Richie joins her, his massive cock throbbing in his hand. Emma, captivated by his size, takes control, greedily sucking him off before mounting him in reverse cowgirl. She rides him hard, her tight cunt gripping his thick shaft, while he pounds her doggystyle, their bodies slapping together in a feverish dance. They switch to missionary, Emma's legs wrapped around Richie's waist, her eyes locked onto his as he fills her with his hot cum.
