USA TODAY BESTSELLING series Vi: If you can't sell a dildo in Vegas, you're doing it wrong. That's why I opened Whipped—a sex toy store. Because sex and Sin City go together like... well, like sex and Sin City. I've seen everything—and I mean EVERYTHING—which is why the guy who comes in every week with a new flavor of arm candy buying yet another set of sex toys doesn't surprise me. But when he becomes my new roommate, well... Lachlan: I'm a male stripper. I'm not ashamed of it—in fact, I fucking love it. I turn girls on five nights a week. With a stare. With a sway of the hips. Then I take them home and fuck their brains out. I live by three rules: No commitments. No falling in love. Only mind-blowing orgasms. Now I want more. But Vi isn't interested in a fuck buddy, and I've never been one to stick to a single girl. They say that what happens in Vegas, stays in Vegas. But when you live here full time... That's when things really get interesting.
