Skip the drive-through car wash this summer and make it a sexy warm-up for you and your guy instead! Opt for minimal clothing (because it's so hot, of course) and go outside to wash your guy's car. To make it extra enticing for him, don't invite him out to join, but make sure you're in plain view of wherever he's sitting inside. Pull out those Paris Hilton eating a hamburger moves, and he'll promptly come out to join. We bet you'll be both inside getting it on in the shower in no time. Or better yet, up against the side of your house for a soapy, sweaty quickie.
