scottish couple visiting amsterdam

hi to all, like many it's been a long time fantasy to watch my wife getting fucked,we have often talked about it but I let my jealousy get in the way ,when we actually got close to doing it once,and now she wont even talk about it any more,anyway being the bad hubby I am we're of to Amsterdam for a few days starting 14/5/08 and I was thinking how horny she gets when she's had a smoke,now to be clear I'm not into the hole sissy thing and I'm not gay or bi curious ,I just get of on the thought of watching her with another guy and definitely joining in ,now I'm thinking if we were to meet someone in Amsterdam and she's relaxed enough it wouldn't be to difficult to make this happen,any help or ideas greatly appreciated

oh she's 37yro 5'6 brunette size 14 really cute face with wonderful full cock sucking lips
