Masturbation blackmail

So today I jacked off on cam to a girl who recorded it and threatened to message all my fb friends with the video, unless I payed them. 2 things wrong with this, most of my friends know I'm quite promiscuous and number most of my fb friends are hot girls, who haven't seen me naked. Don't see how showing them I have quite a big cock could work as blackmail, saves me the job! ahahaha
