It's the collaboration everybody wanted to see for years, big dicked Christina is a Beautiful, Dirrty girl and Britney certainly knows how to rub her the right way!
Britney wasn't lying when she said she was Not a Girl, Not Yet a Woman, she's something much better! Something with all the best features of a woman, but one thing a little different!
The world's most desired woman could only be more desirable if she whipped out her cock to drive you Crazy. Surely then you'd be down on your knees begging her to Hit you, Baby One More Time!
