All Ricky Spanish wants for Cinco de Mayo is margaritas and pussy. He isn't picky about which pussy, but he wouldn't mind getting it on with his bigtit babe of an adopted sister, Alyx Star. Alyx feels pretty into Ricky as well, so she's not shy about looking for an excuse to flirt with him. They agree that they want a party, but their stepdad Ryan Driller tells them it's not allowed. Cinco de Mayo is a holiday with a lot of meaning and Ryan wants to teach them about it. Alyx agrees, but only if they can have a special pinata.

Later, Alyx has just finished setting up the pinata when Ryan tries to sit down and deliver a history lesson. Alyx says she'd like to do the pinata first and even offers to let Ryan have the first swing. Ryan agrees and busts it open on the first try! Out fall a variety of sex toys mixed in with the expected candy. That infuriates Ryan, who insists that Alyx use the toy right now in front of both him and Ricky as a punishment. Since that's exactly what Alyx wanted in the first place, she's all in. Watching his stepsis vibing with her dildo just gets Ricky excited, which prompts Ryan to tell his stepson to help his adopted sis out. That just makes Alyx even hornier, so she goes for Ricky's dick to start sucking him off!

Ryan can barely believe what he's seeing, but once Ricky gets behind Alyx to lick her pussy, Alyx reaches out to tug her adopted stepdad's cock out. Ryan tries to disengage, but Alyx isn't having it and Ryan doesn't truly want to stop having such a hottie sucking him off. Ricky eventually goes from pussy eating to fucking his adopted sis in doggy as Alyx muffles her moans on her stepdaddy's hardon. Ricky takes a seat and Alyx turns around to deep throat him as Ryan bangs her on her side. Next, Ryan takes a seat so Alyx can ride him in cowgirl while continuing to make love to Ricky's cock with her mouth. She gives Ricky a reverse cowgirl ride while Ryan takes a handie until he pops right in Alyx's mouth. Cum dripping down her breasts, Alyx moans in delight as Ricky drives deep inside her and nuts to give her trimmed twat a festive creampie.
