Best friends Amber Summer and Kimmy Kimm like doing everything together. Everything. They've made the decision to start working as a team in therapy. Joshua Lewis, Amber's stepson, informs them that their strategy consists solely of sucking a lot of dick and that's all the life experience they have. Joshua is reminded by Amber that as she hasn't yet licked Kimmy's dick, neither has she. Having said that, they are undoubtedly intrigued.

Pushing the item up to Joshua's butt, the females tell him they need more practice pegging. He agrees to allow them to use him as a test subject for their standard therapy questions, but he still refuses. Kimmy starts interrogating him about his affections for his stepsis, Amber, right away. Joshua is really excited at the mere prospect, so Kimmy asks if she can get the salami out for him. Joshua attempts to explain that Amber isn't allowed to contact, but Kimmy gives her buddy the finger in a double-handed kiss. Joshua can't possibly refuse that? When the three of them get to the bedroom, Kimmy gets on the D and goes full cowgirl. In the end, she manages to persuade Joshua to allow Amber to take a backwards cowgirl ride. Now that they are a full threesome, Kimmy invites Joshua back inside by putting one leg up in the air as Amber rides on Kimmy's tongue. Amber gets on her knees and gives herself a dog-style pussy pounding until Joshua comes out and slobbers all over his stepsister. Joshua acknowledges that their therapy worked as the girls seal their kisses with cummy kisses.
