Penelope Kay and Anna Claire Clouds are getting ready for a Labor Day picnic. Penelope's stepbrother, Codey Steele, decides to prank them. He sneaks up behind them and sprays cleaner on their butts. He tells them that it says spray on flat surfaces, which just pisses both girls off. They decide to tease him and pretend they want to have sex with him, then leave him with blue balls after they show him that their butts aren't flat.

Walking to Codey's room, the girls say they're not mad at him anymore and invite him to their Labor Day picnic. Everything they do is as sexual as they can make it, and Codey definitely notices. They claim that Codey has a fever and tug him to the living room together. Codey stands in disbelief as his stepsis and her hot friend peel his clothes off, allegedly to cool him down. When his boner springs free, Anna realizes that it's really nice and she wants it. She's already on her knees, so she begins stroking and sucking it while also rubbing Penelope's twat to warm her up. Once Codey promises not to tell, Penelope joins in on sucking him off.

Now that they're committed, the girls go ham. There's plenty of pseudo-lesbo action as the girls help each other show off their tits while they take turns sucking Codey's cock. Then Penelope helps Anna turn around and sink down onto the D in reverse cowgirl. While Anna is bouncing away, Penelope sucks her nipples. Then she takes a spin on her stepbro's dick in cowgirl with Anna's assistance. Laying down, Anna welcomes Codey between her thighs and Penelope's pussy on her face. Penelope takes another go with her steprbother's stiffie as Anna rubs Penelope's clit and urges Codey to cum. When Codey pulls out and nuts all over Penelope's stomach, Anna is quick to lap it up and snowball it with her BFF so they can both enjoy his salty surprise.
