Nikki Nutz has a complicated relationship with his stepsister, Lady D. One of the things that makes it hard for the stepsibs to get along is that any time Nikki brings home a girlfriend, Lady D goes ahead and tries to steal her for herself. Today, Nikki has brought his newest amour Zazie home to meet the family. Lady D likes what she sees well enough that she comes up with a plan to make Zazie hers. She waits until Zazie is getting made up in the bathroom to go in and take a shower, which ensures that Zazie sees all the sweet soft curves that Lady D has to offer. Later, Lady D sits with Nikki and Zazie on the couch so she can massage Zazie's feet. Nikki tries to tell Lady D to cut it out, but Lady D is having none of it. Eventually, Lady D catches Zazie alone and guides her to the bedroom. Zazie is open to Lady D's advances. She lets Lady D lay her down on the bed and pull her shirt down so that Lady D can indulge in her tight little titties and hard nipples. Then Lady D moves further south, pulling Zazie's panties aside so she can dive in for a pussy feast. She's just getting into the groove when Nikki walks in on them and catches them in the act. Instead of acting ashamed of themselves, the girls invite Nikki to join in on the fun. When faced with two hotties who want to make his dreams of a threesome come true, Nikki would be foolish to decline.Climbing into bed, Nikki lets the girls take turns sucking his hardon. Then he gets to enjoy the ride as his stepsis climbs aboard his fuck stick. The girls eventually trade places, with Zazie bouncing away on Nikki's cock as Lady D fondles her breasts and rubs her clit. Getting on her hands and knees, Lady D goes back to eating Zazaie out as Nikki bangs her from behind. Zazie takes her own turn in doggie as Lady D lies beneath her in an almost-69. Nikki fucks his girlfriend right up until he blows his load, glutting Zazie with a creampie that drips down into Lady D's waiting mouth. Licking Zazie clean, Lady D basks in a shared conquest with her brother.
