Madi Collins has invited her BFFS Lulu Chu and Jessie Saint to celebrate the Fourth of July. They decorate the house and then beg Madi's stepbrother, Codey Steele, to drive them to the amusement park. There's a new ride that they want to go on. Codey claims none of the girls are tall enough to ride, and he won't take them unless they measure themselves first. He gets a measuring tape and then claims that the girls need to take their shirts off so they appear taller. Even with the shirt trick, none of the girls quite meets the height cutoff. Codey then offers to act as their guardian so they can all ride, but on one condition: Madi needs to suck his dick while her friends watch.
