Victor Palmas' cock twitches as he watches Tina, his stepsister, writhe on the bed, her body slick with oil from her self-administered massage. Tina's fingers dance over her clit, then plunge into her wet cunt, her moans filling the room. Victor can't resist joining in, his cock hard and ready. Tina grins, taking his cock into her warm, eager mouth, sucking him deep. She straddles him, her tight pussy sliding down onto his thick cock, riding him cowgirl-style, her tits bouncing as she fucks him vigorously, their taboo incestuous passion building until Victor erupts, filling Tina with his hot cum.
