Venus and her stepbrother are always bickering. The pair seem to have some sort of weird attraction towards each other, but their sibling rivalry gets in the way. Their stepmom, Madison, is tired of hearing the two of them arguing all the time and finally puts her foot down. After reading a TeamSkeet book on family discipline, Madison has all of the answers she's been looking for. She starts by making Venus and Parker kiss. It's a weird sensation, but it makes Venus super horny. She can't believe she's doing something as wrong as kissing Parker, who she has known forever as her stepbrother. Parker is also turned on but knows it's wrong. Madison sees that their kiss has made them hot and heavy, so she leans into it and makes the stepsiblings go all the way. Plus, Madison likes it just as much as they are, and the horny milf is feeling slutty and down to see how far she can take this fling. Parker sucks on his stepsister's perfect tiny nipples and fits her titty in his mouth. It's weird and fucked up, but no one wants the threesome to stop because everyone is feeling extremely turned on. Parker moves downstairs and goes to town on his stepsister's pussy, lapping up her juices and sucking on her clit until he has her shrieking with delight. The petite chick has never known pleasure like this and is feeling super kinky and slutty at this moment. Madison watches as her perverted plan unwinds. Soon, the group can't stop fucking around with each other, and it isn't long after that Venus has Parker's cock deep down her throat. He pushes himself deeper, and Venus doesn't stop blowing him until he shoots his load. Madison watches, and she can feel herself getting wet. She wants a turn with Parker, and it would be even hotter if she could mess around with Venus, too. In the bedroom, Venus and Madison tend to Parker's throbbing cock. Never in a million years did he imagine he'd be getting his cock sucked by his milf stepmom and cute stepsister, but he knows he has to prove himself and fuck the both of them as they've never been fucked in their lives. The girls prove to be total powerhouses, and they ride his cock like pros, taking every inch, building him closer and closer to climax. Venus thrusts her sweet hips around as she rides him, knowing she's making it hard for her stepbrother not to cum. Madison is impressed by her stepdaughter's slutty skills and can't wait to get a taste of her dripping wet snatch. When Parker can't hold his load any longer, he cums hard for the girls, giving them a frothing shot of hot white nut.
