Alina Lopez and her friend Kyler Quinn talk shit about Alina's stepbrother, Nathan Bronson, in private as they snap sexy selfies of themselves. Whipping out their tits, they start taking photos to send to their boyfriends. The girls agree that they think Nathan would be hot if he were to change everything about himself. After another round of selfies, Kyler heads out to fuck her boyfriend. When her friend leaves, Alina keeps on shooting pics with her boobs out. She has just flashed her pussy for the camera when she drops her phone. It rolls under the bed and when Alina tries to retrieve it she gets stuck.

When Alina hears someone in the hallway, she calls for help. She expects that it's her boyfriend since he's due to arrive any minute, but it's her stepbrother. Nathan hasn't ever seen his sister in such a compromising position before and he finds it incredibly hot. When Alina says he can fuck her if he needs to but to hurry up, Nathan takes her word for it and slides it in. Without knowing who's banging her, Alina is full of compliments for how good it feels. The mutual delight lasts until Nathan speaks and Alina realizes it's her stepbrother's cock inside her. She tells him to get her out from under the bed, which he reluctantly does.

Although Alina is upset, she's also conflicted because Nathan's got a really nice dick. She decides that since they've started they might as well finish. Alina urges Nathan to come closer so she can climb onto the bed and suck her pussy juices off his fuck stick. While his sister is sucking him off, Nathan reaches forward to run down her slick pussy. She makes a compelling argument that they should keep going, so he finally agrees to continue banging when Alina rolls onto her back and spreads her thighs to welcome him in. Their rough and tumble encounter continues as Alina climbs on top of Nathan and slams home on his hardon. Riding Nathan so hard her bottom slaps his balls, Alina tells Nathan to cum for her. He misunderstands, cumming inside her for a creampie that leaves them both feeling awkward about their brother/sister encounter.
