Nathan Bronson is grounded, so he's stuck hanging out with his stepsister Paige Owens and her friend Lily Larimar on New Years eve. The girls decide to screw with Nathan by getting naked and putting party hats on their tits. They tell Nathan to clean up, but to start with the party hats. He starts with Lily's boobs, then tries to move on to Paige's. Paige is freaked out, but Lily tells her she owes Nathan for being mean. When Paige is disgusted to see that Nathan has a boner, Lily decides to help him out in repayment for Paige's rudeness.

Pulling Nathan's dick out, Lily strikes it for a minute before declaring that she's super wet. She lays down on the couch and pushes her thong aside in an invitation that Nathan is quick to take her up on. Paige tries to ignore her friend getting her pussy eaten by her stepbrother, but she kind of wants in on the action. Sliding her hand into her undies, she starts masturbating. Eventually, Lily notices and invites Paige to try Nathan's tongue on for size. Since it's just her stepbrother, Paige agrees.

After experiencing Nathan's mouth with the help of Lily's tongue playing with her titties, Paige is eager to know more about what her stepbrother can do. The girls get on their knees to present a pussy buffet so Nathan can get his dick wet in first Lily's snatch and then Paige's. Laying Nathan down on the couch, Lily climbs aboard for a stiffie ride as Paige sucks her nipples to hard sensitive peaks. Then Paige takes her place on the couch so that Nathan can drive deep. After bringing his stepsis to a moaning climax, Nathan pulls out to cover her snatch in jizz.
