I came across this rare video uploaded by a user. In the long video we can check innocent Christy sleeping while an unidentified perv starts jerking off over her. After some minutes her lands his sperm on Christy Marks chin. She continues sleeping while the guy unloads his semen over her. Take a look at it:

Some people would argue that the girl is not her. Here a pic of Christy  getting some cum on her face in one of her  first videos for her site ChristyMarks.com
