Penelope wants to throw a Memorial Day party with a marine theme, after all, her stepdad is a Marine himself! However, there is one small issue, her stepbro, Conor. He is more of a loner and hates parties, so she is going to need to make a good deal if she wants to convince him to let her throw a party. A blowjob later, Conor yearns for a second round, so he tells Penelope that she has a reputation for giving sloppy blowjobs, a statement that she quickly proves wrong. In the end, Penelope is enjoying this as much as Conor, so she convinces him to go further, luring him with her sexy marine costume.
