Riley Jean's mom has separated from her wife, which means that her ex-stepbrother, Tyler Steel, no longer lives with them. Tyler tries to come over when Riley's mom is at work so he can do laundry. Riley doesn't want to be alone with Tyler, so she tries making plans with her friend. When she goes out to let Tyler know, Riley finds him in his boxers. He eventually convinces Riley to strip down to her polkadot bra and panties. The stepsibs are hanging out together when the doorbell rings. Riley freaks out and tells Tyler to hide.When it turns out to be a false alarm, Riley and Tyler cuddle up once again. Tyler eventually coaxes Riley into showing off her tits. She puts them away, but Tyler takes the opportunity to pop out his hard dick as a quid pro quo that Riley didn't necessarily ask for. Although Riley plays coy, she's definitely into her bad boy stepbrother in a way that can't be denied. She lets him talk her into touching it. In return, Tyler wants to do some touching of his own. Next thing Riley knows, her badass bro is fondling her titties and pointing out how wet she is. Leaning in, Tyler samples Riley's pussy juices in a very convincing argument that they should go ahead and explore their passion for each other.Riley eventually gives in, opening her mouth to start sucking her stepbro off. They enjoy an acrobatic 69, then return to the couch where Riley climbs onto Tyler's cock to learn just how incredible her brother's big dick feels as she rides it. Tyler's hands are everywhere, spanking, caressing, and helping Riley set the pace. Putting Riley on her back, Tyler sinks balls deep into her greedy twat. Then he spoons with her from behind. Riley gets to enjoy one last climax as Tyler gives her a rough and rowdy pussy pounding. She returns the favor of those big Os by getting on her knees and letting Tyler blast her with a facial of cum.
