In my days of 30 min punting I sometimes wouldn't get close up with their pussy until sex. Massage then a BJ with girls that keep their distance at the bottom of the bed whilst giving oral meant that you hadn't had your face within three foot and also no chance to put your fingers down there and give them a crafty sniff. Then when you did doggy the smell would hit you, the combination of your member pumping in and out like a Victorian beam engine, thus disturbing the fishy juices, and your nose being directly over the action meant that you were suddenly hit with a smell like the end of a hot summer's day at Billingsgate Fish Market. Too late though to pack your bags and leave, just try not to breathe in through your nose, unload quickly and get out of there. Perhaps WG hygiene is improving though as I can't remember the last truly stomach churning fishy experience.
