Madi Collins may be a bit of a bad girl, but she’s decided to turn over a new leaf. She needs her stepbrother Jason’s help to do it. Since Madi only owns slutty clothes, she needs to borrow money to buy a few more demure outfits. Jason will only lend Madi money at a high interest rate, or if she sucks his dick. Madi figures it’ll only be a smart economic decision to suck her stepbrother’s dick instead of paying back a ton of money. Still skeptical, Jason points out they’ve done this tons of times before and that Madi enjoys it. Right before taking Jason on in a deep throat BJ, Madi swears it’s the last time because she’s a good girl now. She insists that Jason cum fast and that she’s totally not enjoying it.

The next day, Madi is studying in further pursuit of her new good girl lifestyle. Jason tells her that he’s been thinking about it and he’s come to a decision. Madi has been asking to use Jason’s car and he’ll let her do it, but only if she lets him fuck her from behind. She agrees, buy only if he lets her study while they’re boning. Jason gets behind Madi and tugs up her miniskirt and peels off her panties so he can slide on home from behind. Although she initially tries to pretend she’s not loving every inch of her stepbro’s dick inside her, Madi soon gives up the pretense. Pushing Jason onto his back, Madi goes about having her way with him.

Another blowie that lets Madi suck her own juices from Jason’s fuck stick is just the beginning. She straddles Jason’s thighs to sink down on him in reverse cowgirl, which gives Jason the chance to admire his spinner stepsister’s big ass with plenty of squeezes and spankings. Then Madi turns around so she can rub her clit as she keeps on bouncing away on Jason’s hardon. She turns around once again so that Jason can hold her in place and piston up into that greedy twat. When Madi finally falls onto her back, Jason gives it to that plump pussy until she’s moaning one last time. Pulling out, he gives his stepsis a facial that even covers her glasses. When Jason tries to call Madi on how bad and slutty her behavior just was, Madi agrees that she is indeed a slut for her stepbrother.
