Leo Valentino is getting blasted by his stepsister Daisy Fox and her friend Cecelia Taylor as they nail him with water guns. The girls follow Leo inside to keep on soaking him. When Leo grabs the watergun from his stepsis, Cecelia makes sure to spray him in the crotch in retribution. That makes Leo storm off.

The girls reflect about how Daisy wants to fuck her stepbrother. Cecelia wants that too, so they come up with a way to make it happen. Changing out of their bikinis, they switch to white shirts and then go to work blasting each other with the waterguns. When Leo calls them on breaking the rules, they peel their shirts off. That's when Daisy tells him that they're going to fuck. To prove their points, both girls drop to their knees to pull out Leo's stiffie and suck him off together.

The trio hits up the bedroom, where Leo plunges balls deep into Daisy's snatch in doggy as Daisy eats Cecelia out. Then it's time for Cecelia to take a turn in the middle as she cradles Leo between her thighs and balances Daisy atop her mouth. When Leo lays down on the bed, Cecelia rides him in cowgirl even as Daisy gives Leo's tongue something to do. As the threesome winds down, Daisy gives it to Leo in reverse cowgirl while he laps the taste of their love from Cecelia's pussy lips. They keep it up like that until Leo gluts Daisy with a creampie, leaving them all sated.
