Tips on getting a guy really turned on?

Okay, so I have done pretty much everything sexual possible.. But, this guy I like wants to "mess around" neither of us want a relationship, but we just want to have fun. So while we make out I want to surprise him with some CRAZY stuff. He has been with a lot of girls so he's experienced a lot and I want to be better than all the rest. My plan is to just be all over him an touch and kiss everywhere. Maybe even surprise him with a little oral. I know I sound just like a whore, but I really just want to make him go crazy and want me (in bed) soooo bad. I want him to think I'm a freak (in a good way). So what are some kinky, crazy things I can do to really reaaaally get him going? Be very descriptive please! Oh and we'll only have like maybe 15 minutes, so it cant be anything that take forever. Thanks!
