why don't you try having a threesome ?
talk to your husband about it and if he agrees go to a bar pretend that your not together and once your there you go and find a girl that appeals to you. Tell her you would like to go back to your place, but there's a catch ... my husband is probably going to join us .. or at least watch us ....

hopefully everything will go well and you'll get to taste some mmmm mmmm good pussy

tell me if it works out ...
