Sia Lust and her stepbrother, Nathan Bronson, have gotten together in the past. Their fuck fest was supposed to be a secret, but Sia couldn't stop herself from sharing with her best friend, Lily Larimar. When Nathan drops into Sia's room to deliver her cell phone that she left lying around, Sia gives him a hug. Lily picks up on how awkward they are and asks if it's because they boned down. Nathan and Sia are unhappy with Lily for talking about it, but Lily stays the course. She claims that it's national brothers day and they should therefore get together again so Sia can prove how much she appreciates Nathan being her stepbrother.
When Lily's initial idea doesn't work, she isn't done. She turns to Nathan and claims that Sia says he has a really nice dick and she wants to see it. Nathan eventually gives in to Lily's pleading. Once Lily has admired the D, she begs Sia to stroke it. While Sia is doing as Lily wants, she finds that she's unbearably turned on. She needs the cock so much that she begs Nathan to give it to her, with Lily's blessing of course. On her knees, Sia takes a proper pussy pounding courtesy of Nathan as Lily watches and masturbates to the sight. They get Nathan on his back so that Sia can climb aboard and enjoy herself in cowgirl. When Sia falls onto her back, Lily manages to convince Nathan to glut his stepsis with a big ol' creampie.
Dripping with her stepbrother's jizz, Sia dismisses Nathan, telling him that they're done with him. When Nathan is gone, Lily licks the cum from Sia's twat. While she's enjoying her treat, she arranges herself so that her pussy is overtop of Sia's mouth, creating a lesbian 69. The girls enjoy each other's most tender bits for a while, but it's not quite enough to make either of them cum. They get there by going pussy to pussy and tribbing together. As their scissoring brings first one and then the other to climax, they fall backwards and bask in the afterglow of a raunchy time together.
Hime Marie and her BFF Lulu Chu have just graduated! As a prank, they have decided to go nude beneath their graduation gowns. They're chatting about what they're not wearing as Hime's stepbrother, Tony Lovelock, overhears them. He comes up to hit on the girls, especially Lulu. In an effort to impress them, Tony whips his cock out. It's a bit of a mistake, though, because it's not long before he accidently cums all over Hime and Lulu's feet. Grossed out, the girls retreat to Hime's bedroom.
Although Tony didn't get instant gratification for his efforts, he follows the girls and learns that they were both pretty turned on by his display. As Tony watches, the girls slip their hands beneath their graduation gowns to touch themselves while reminiscing about Tony's nice dick. Tony can't help himself; he comes up and lends Hime a hand while she assumes that it's Lulu touching her snatch. When Hime realizes it's really her stepbrother, she hesitates initially, but with Tony and Lulu both urging her on Hime agrees that they should all fuck.
Peeling off their robes, the girls exchange deep kisses as Tony samples their pussy buffet in doggy. Rolling onto her back, Hime pulls Lulu until she can lap away at Lulu's twat. Meanwhile, Tony gives Hime's snatch the same treatment. Scooting backwards so that she creates a double stack of pussies, Lulu makes out with Hime as Tony once again samples both their charms. When Tony moves low to Hime's meaty snatch, Lulu turns around to ride Hime's mouth in reverse cowgirl so she can watch Tony bang his stepsis. As Tony gets closer to cumming, he lays on his back as the girls take turns riding his fuck stick. When they're both finally sated, the girls hop off the D to lick and suck Tony's shaft until he delivers a mouthful of cum for Hime and Lulu to snowball.
Stanley Johnson is hanging out with his new stepmother and stepsister in Europe. He and Anie Darling don't get along at first, but it's pretty clear their bickering is sexually motivated. When Stanley brings a bowl of lollipops to the couch where Anie is playing on her phone, the two argue over who gets to eat all of them. Anie is pissed that Stanley won't let her have them so she calls her mom in. Mom scolds both kids and takes the lollipops away, leaving them to fight over the remote control. Anie wins that scuffle, but Stanley pulls up Anie's shirt to expose her tight titties and then takes the control as she's surprised.
Stanley shoves the remote down his pants to dare Anie to come and get it. She doesn't wait a second before she unsnaps Stanley's jeans to get the remote. She gets that and more when his big hard dick pops out. Anie knows how to take what she wants, and what she wants right now is her stepbrother's cock in her mouth. Dipping her head, she starts blowing him without a second thought. Stanley likes his sis's mouth much better when it's wrapped around his dick, so he lets his hand creep around to her bottom. Relieving Anie of her shorts, Stanley pulls her into his lap, where he eats out her ass and finger bangs her dripping snatch.
It's not a surprise when Anie scrambles up into Stanley's lap so she can seat herself on that fine cock. Bouncing away with her stpebro buried in her bald pussy, Anie throws her head back and moans in delight. When she finds herself on her back with Stanley spooning behind her, Anie lifts one leg high in the air so he can go deep. On her hands and knees next, Anie watches over her shoulder as Stanley gives it to her from behind. Her moans are long and loud, the perfect approval for Stanley's deep penetration. When Anie is just about ready to cum, she rolls on her back and spreads herself wide open for Stanley to bring her off. In return, Anie resumes her blowjob until Stanley nuts in her eager mouth.
Khloe Kapri's mom has recently remarried and Khloe is really into her new stepdad. She spends a ton of time asking her new stepbrother, Robby Echo, where his dad is. Each time Khloe asks, she is wearing fewer and fewer clothes. Robby gets to looking at Khloe, and at first she gets pissy at him for being a pervert. Later, though, Robby finds Khloe sitting on the couch, despondent, wearing only lingerie. She confesses that she walked in on her stepdad and realized that he has a nice dick and that she wants some of it for herself. She's been shut down, though, and now she's horny and flying solo.
She has gotten to thinking, though, that if Robby's dad has a nice dick then Robby might, too. She goes ahead and shows off her lingerie getup for Robby's pleasure. She even goes so far as to take Robby's hands and press them to her titties. When it's evident that Robby is nice and hard, Khloe tugs his fuck stick out and opens wide so she can start sucking! Her sloppy BJ is a convincing argument to Robby that he should take things a step further and give Khloe everything she wants.
Khloe starts their fuck fest off by getting to her feet and seating herself on Robby's dick. She bounces away, but Robby has a better idea when he gets Khloe on the couch so he can properly fuck her in doggy. Then Robby lays down so Khloe can ride him in cowgirl. When she has hopped off the D and gotten on her back, Khloe spreads herself wide open for Robby to bring her off one last time. He delivers in Khloe's search for an orgasm, then pulls out to cover her muff in a climax of his own. Khloe admits she's suddenly a lot more into having a stepbrother now.
