Nikki Nutz is enjoying some personal time with porn on his phone when his stepsister, Ivi Rein, walks in without knocking to ask if he has any laundry for her to do. Although Ivi acts like she is embarrassed, she's really quite turned on by what she saw. She decides to take a bath to enjoy a little masturbation of her own, but Nikki interrupts her when he wanders into the washroom. Now the stepsiblings are even since they've each gotten an eyeful of the other as they've been in the middle of some personal time.

Eventually, they sit down to breakfast together. Ivi suggests that maybe they should both start locking the door when they're in the middle of their me-time. Nikki agrees and thinks that's the end of it, but before she drops it, Ivi decides she wants to see what kind of porn Nikki is watching. She realizes that it's stepsibling porn and immediately starts teasing Nikki by keeping his phone. He chases Ivi into the living room, where she tells him that she'll return the phone if he does what she tells him. She begins by having Nikki take off her socks, then having him kiss her feet. She gets him to kiss higher and higher up her legs until his face is right in her pussy. That's when Ivi tells Nikki that this is the key to getting his phone back.

Once Nikki has committed to eating Ivi out, she isn't about to leave her stepbrother hanging. She gets on her belly to suck Nikki off in a languorous blowjob that leaves her heels kicking in pure delight. From there, it's simple for Ivi to climb on top of Nikki and pin him down as she slides down onto his hardon. Rocking her hips, she gives him a taste of fucking his stepsis. Then she gets on her back and lets Nikki do some of the hard work. He begins on his knees in front of Ivi, but quickly winds up banging her as they spoon. Back in a seated position, Nikki watches rapturously as Ivi rides him once again, this time in reverse cowgirl. She lets Nikki finish her off as she is on her knees in doggy, rocking back to meet every one of his strokes. Sated, Ivi pushes Nikki onto his back so that she can suck him off until he pops in her mouth with a cum shot that drips down her chin. Ivi finishes their sexcapades by declaring that Nikki has earned his cell phone back.
