I’m not sure exactly when advertising and pornography crossed swords (pun intended) but doesn’t this ad from a “classy” parfumier do just that? If they decide to follow it up with something even more daring, where is there to go? Come Even Closer? Or maybe something really classy like Pearl Necklace. Sorry. I didn't make the ad up, I'm just running with it.
Now get your minds out of the gutter and get back to your books.
