Ms Faris and Kiara Cole are playing games in the yard on Cinco de Mayo while exchanging heated glances. Kiara spies Chris Diamond, Ms Faris's stepbrother, and suggests they fuck with him. Chris comes over as the girls talk about how into Kiara Ms Faris is. When he gets close enough, the girls offer to let him play ball with them because they're really good at playing with balls. They bounce and jiggle to tease Chris until Claudia Monet calls the kids in to help her and Chris Valiant set up for the party.
Once the trio is indoors, Kiara does her best to instigate a thing between Ms Faris and her stepbrother. Ms Faris is freaked out by Kiara flashing her stepbrother her titties, and even more freaked out when Kiara offers to fuck Chris, but only if Chris also bangs his stepsis. In an effort to get a yes from both of them, Kiara drops to her knees and starts sucking Chris's hardon even though Chris and Ms Faris's parents are right there! Eventually they are all in agreement since Ms Faris really wants to fuck Kiara. They relocate to the living room to get more intimately acquainted.
Ms Faris remains a little bit shy, but Kiara eventually draws her in to give Chris a tandem blowjob. Once the girls are done sucking, Kiara lets Ms Faris know that she needs to fulfill her end of the bargain by hopping on to Chris's dick and riding him. Kiara is there every step of the way, sucking Ms Faris's titties and Chris's fuck stick. Then she takes a ride of her own, pulling Ms Faris to Chris's mouth so she remains in the game. Kiara gets onto her back next with Chris buried between her thighs and Ms Faris riding her mouth. Replacing Kiara on the couch, Ms Faris takes another round of pussy pounding from her brother while Kiara eggs them both on. As Ms Faris cums one last time, Chris nuts inside her for an unexpected creampie surprise.
