Madi Collins is hosting a Fourth of July celebration for her best friend Lulu Chu and her boyfriend Jessie Saint. After decorating the house, they persuade Codey Steele, Madi's stepbrother, to take them to the theme park. They're interested in riding a new ride. None of the girls, according to Codey, are tall enough to ride, and he won't take them unless they take a self-measurement first. After grabbing a measuring tape, he says the females should remove their shirts to make them look taller. None of the females quite reach the cutoff height, even with the shirt trick. Then, in order for them to all ride, Codey offers to take on the role of guardian—but only if Madi sucks his dick in front of her friends. Madi fulfils her promise to Codey by getting down on her knees and having a wild time with her stepbrother's cock after agreeing to her terms. Lulu and Jessie initially observe while Codey persists. But eventually, they are unable to resist that attractive fuck stick. Codey ultimately finds himself savouring a three-girl BJ from his stepsis and her diminutive companions as they gradually get closer. After moving into the bedroom, the three of them lie down and allow the females to continue sucking him. After exchanging kisses, the girls decide that Madi ought to board the D and go on a stiffie ride first. Next, Lulu leans forward and laps at Jessie's twat, taking Codey's cock in the process. After ensuring that her buddies are having a good time, Madi gets up on top of Jessie's face and rides her friend's mouth. Lulu eventually moves out of the way, allowing Jessie to move forward and enjoy Codey's dick tucked into her snatch. Madi laps at Lulu's titties as Lulu takes turns sitting on Jessie's face. Madi lets Codey reach his limit of endurance in her velvet glove as he is about to cumming, lying on her back. At the last second, he leaves, nuttting on Madi's stomach to make a mess that Jessie and Lulu love. Codey tells the girls a secret as they are happily kissing one other: nothing he does will be able to get them to follow the rules.
