Check out Dana Kane. She's really serious about her spankings. Most of her videos are F/F because that's what sells, but she likes to spank guys, too. I think her rate is $300 for a nominal hour ("a spanking is as long as it takes" she said once), but she doesn't do half-hours, which is my thing.

Just for fun, go to the Heart Attack Grill while you're there, and let your waitress know that you're really into spanking. You'll get more than three smacks. I know! The burgers are actually pretty good. Get a single one and you won't feel silly. And you can get paddled even if you DO finish your food.
