Eliza Ibarra and her BFF Gianna Dior are getting ready to go to a Cinco de Mayo party. They visit Eliza's stepbrother, Van Wylde, to tell him their plan since he is in charge while their parents are out. Van tells the girls that they can go to the party, but only if they first agree to watch a show about Cinco de Mayo since the holiday is about more than getting drunk and eating tacos. Gianna has no time for learning, so she makes a deal with Van: If she and Eliza can get Van's dick hard, then they can just head out without watching anything educational.

Van agrees to Gianna's terms. The girls strip Van out of his clothes and put a sombrero on his cock so he can't try to hide it if he gets hard. The girls go to work, peeling off their shirts and then making out in front of Van. Sure enough, when Gianna whips the sombrero off Van's willie, he's hard as a rock. Eliza is a little bit hesitant to escalate things further, but Gianna wants that nice cock. She leans in and starts licking, which ultimately encourages Eliza to join her. Soon they're delivering a double BJ.

Gianna still wants more, so Eliza helps her friend onto her stepbrother's stiffie. Eventually, Eliza gets a turn of her own to ride Van's fuck stick while Gianna watches and masturbates with a maraca. When it's Gianna's turn to enjoy another pussy pounding, she lays on her back while Van gives it to her and Eliza rides her mouth. Gianna gets her own pussy licked when Eliza gets on her hands and knees for a doggy style pussy pounding that leaves her mouth at the perfect licking level. They keep it up until Van reaches his finish line and pulls out to bust a nut all over his stepsister's lovely ass.
