Mackenzie Moss and Emma Starletto have made a mess along with Seth Gamble, Mackenzie's stepbrother. Emma is kinda into Seth, so as they all watch TV in the living room together she flirts with him by flashing her tits. Mackenzie catches Emma flirting and tries to tell her friend to stop. Instead, Emma talks Mackenzie into joining in. As the girls both flash their perky little boobs, Seth stares, frozen. He can't look away as Emma and Mackenzie show off their asses. Seth is saved from his awkwardness by Krissy Lynn, who comes home and lectures the kids for their messiness.

Even though Mackenzie's mom is right there, the girls keep on taunting Seth with their tits. She never quite catches them in the act, but Seth bides his time. As soon as Krissy leaves the room, he turns the tables on the girls by whipping out his stiffie. Mackenzie isn't terribly into it, but Emma sure is! It's not long before she's deep throating Seth's dick. Mackenzie can't help but be turned on as she watches her friend blow her stepbro, so she doesn't exactly put up a fight when Emma invites her to join in. Soon the girls are taking turns sucking cock and slurping Seth's balls.

Emma gets the first taste of Seth's fuck stick as she bends over to take it from behind. Then she helps Mackenzie to lie back and enjoy herself as Seth gets to sample his sister. Emma waits her turn, then climbs on top of Seth's hardon and starts riding him. Not to be outdone, Mackenzie gives Seth a reverse cowgirl ride as Emma licks her hard nips. The girls have just managed to finish Seth off with another double BJ that leads to him nutting in their mouths when Krissy returns and freaks out at the family affair.
