Rocket Power and Ace Bigs spend the day doing their thing. And their thing is nothing more than playing video games. Just then Rocket's busty stepsister shows up and tells him she needs his help. He ignores her completely. Apparently, both step-siblings have been fucking lately. Ace can't believe what he's just heard. A practical demonstration is what he needs to give veracity to this story. So the two friends and the stepsister have fun practicing an interracial mmf threesome.
