I'd do Kate moss first, then I'd last a bit longer with Rihanna. If I did her first I'd shoot my muck after about three strokes, if I've emptied the pump action yoghurt slinger first I might get to as many as seven!
Moss then Rihanna for me, or alternate between them. Just keep the door locked so if i pop too quickly i can get another go..
Moss every time. Rhianna does nowt for me at all. Eyes too far apart and she's got a massive foreheed. I'd have a right good go at Moss though.
