My favorite co-ed-turned-porn star Belle Knox continues her sexy and impressive path through the world of porn. Belle recently took to her Twitter account to give all her adoring fans (and jealous detractors) a sneak peek at her forthcoming photo spread for Penthouse Magazine. The Duke University freshman teased a picture of her wearing some sexy black lingerie, peering intently at the camera. I wonder if she'll auction off this outfit. If so, I'm bidding! I appreciate Belle's enthusiasm with her career, but I'm getting kind of concerned that she might not be hitting the books too hard. Regardless, she sure has me hard!
