Molly Little has just moved in next door to Cory Chase and her stepson Alex Mack. Cory introduces Molly to Alex and then tells Molly that she's welcome here any time. Molly takes Cory up on the offer a few days later, asking if she can borrow some batteries. When Cory learns the batteries are for a vibrator, she offers them up and then offers to online shop for more sex toys with Molly. The next day, Molly plants herself in the kitchen and tells Alex that she's free use now.The following day it becomes clear that Cory and Molly have a free use arrangement when Molly goes down on Cory as she's chopping veggies. Alex walks in on the girls having a lesbian moment and doesn't quite know how to react. Later, he walks in on Molly going to town on his stepmommy's hairy cooch once again as Cory reads a book. That's when Alex decides to take Molly up on her free use announcement. Coming up behind her, he whips his dick out and slides it in so he can bang Molly in doggy and smack that ass as Molly keeps on lapping at Cory's twat.When Molly turns over onto her back, Alex sinks back home as Cory rides Molly's tongue, first in cowgirl and then in reverse cowgirl. The girls then work together to suck off Alex's cock in a double BJ with ball sucking. When Cory finally gets a taste of the D, it's in reverse cowgirl as Molly jiggles her bouncing titties. Throwing Cory onto her back on the couch, Alex keeps boning his stepmom while Molly rides her tongue. Alex keeps it up until he pulls out in time to blow his load on Cory's muff, giving both girls a treat to lick up and then kiss from each other's tongues.
