It's not necessarily their looks. It makes us less self-conscious, and thus it's easier for us to enjoy ourselves. We want to know you're loving it and want us to love it, too. To hone your bad-boy persona, breathe against our ear, grunt when you pick us up, and pant while thrusting. As for dirty talk, let it rip.
Girls dig it.
We're just inherently shy about it, so make your talk part Romeo, part porno till we get rolling. If this gets us going, take it up a notch. If we're really going, call us your dirty little girl. This stuff can be catchy. Before long you could find yourself sleeping with the depraved girl you've been fantasizing about.
