Zazie hadn't realized that Nikki was getting those signals, so she freaks out when Nikki rams into her from behind. Once she is through her initial freakout, though, she realizes that she kinda liked her stepbrother's dick. Since she's already on her knees, she takes the opportunity to stroke it and admire the length and girth. Then she leans into start sucking Nikki off. When Zazie peels off her dress and climbs onto the couch, Nikki is all ready to rumble. Climbing off the D, Zazie sucks her own juices from Nikki's cock as she urges him onto his back. Turning around, she gives it to Nikki in reverse cowgirl. Then she gets back on her hands and knees so Nikki can indulge in the doggy style delight that began this whole coupling. Moaning long and loud, Zazie makes no secret that she's totally into it. The stepsiblings finish their romp with Zazie on her back, humming with orgasmic delight as Nikki gluts her with a creampie that leaves her totally sated.
