The purpose is simple, fucking in front of the webcam so the whole world can see what kind of slut your are. Why? I dont know, i guess they get off on it or something. So, the task doesnt seem to be that difficult but there is a little problem, the dude is camera shy. She sucks his flaccid dick for a couple of minutes and then realizes she is in a hopeless situation, his dick isnt going to get hard today.
