Athena and Joshua have a weird sibling rivalry. As of now, they’ve learned that their step-cousin Aria is coming to visit. Athena has always been jealous of her, and now that Aria has a new boyfriend she likes, she makes a little deal with her stepbrother: if he manages to seduce her step-cousin, she’ll let him fuck her, but if he fails, she’ll get his car. To convince Joshua, Athena seals the deal with a nasty blowjob, getting a taste of his stepbro’s cock for the first time. Now on board, Joshua quickly seduces Aria, who lets his step-cousin play with her pussy. Little does she know that Athena is watching from afar, recording how Joshua fingers her. When she’s about to cum, Athena interrupts and tells her that she will have to as she says if she doesn’t want her boyfriend to find out. To Aria’s surprise, what Athena really wants is to play out a fantasy: putting on a cute outfit and fucking Joshua alongside her!
