Jason tries to claim that he wasn't going to do anything wrong, but Lily is positive that he was going to fuck her friend. Eventually she puts out there that she wants Jason to fuck Anna because she wants to watch. Jason agrees, and Lily begins masturbating as she watches them go at it. Anna loves to share, so it's no surprise when she offers to let Lily join in on the fun. Jason keeps pointing out that it's wrong, but he's not about to turn down the opportunity to fuck his hot stepsis and her friend. With Anna cradling her head against her soft body, Lily lays down and whimpers with delight as Jason shows her how good it can be with his big dick.
Now that they've officially moved into threesum territory, the girls can explore all the naughty things they've ever wanted to do with Jason. Anna gets on her back with Lily riding her mouth and Jason pounding her cooch. Then Jason lays down so that Lily can take a spin on his fuck stick in reverse cowgirl. The girls trade off, taking turns nicely as they each enjoy a ride and then each take a doggy style pussy pounding. As Jason reaches his climax, he pulls out and blasts his load all over Lily's back. Anna is happy to lick her BFF clean and then share her treat with Lily in a kiss before Jason kicks them out.
