Porn DVD and Twins (NWS)

Got a porn DVD the other day. Put it in the player and pushed play. But all I could see was just a dark, blurry picture of some fat bastard holding his dick...
then I realised I hadn't turned the TV on

My mate is shagging twins who both like it up the arse. I asked "How do you tell them apart?"
"Oh that's easy he said, Sally's got massive tits with a nice smooth pussy and Derek's got a moustache and big bollocks"
