Does anyone remember the videos (I think there ended up being two) that were titled "Cause and effect" or something like that involving an amateur couple? Basically, the boyfriend (who is African American) was sitting behind his girlfriend (who is White) on the bed, with his hands sort of wrapped around her side like in a bear hug, and then he starts tickling her like that? She has really good reactions. I think the premise was that she had sassed him before or something, and this is how he was taking it out on her. Sorry that's not much to go on.
