The time passed by and I was happy to watch her more enthusiastic during sex. One day she asked to me whether she can do sex with her new friend. Init...ally I was hesitated as this was a great taboo in our society. Wife in our society is a pious thing which is kept devoted whole her life to one man, while the man are rather at liberty. I was however in fantasy to watch my wife having sex with other man, so I permitted her. She kissed me passionately and told me that any day she will do this and. I walked over wondering what the hell she had got into and with my cock already stirring in my jeans. Mel turned to me and said "we've been invited to a party." The leader laughed, "hell, we're all gonna fuck your bitch crazy an she say she want you to watch!" They all laughed and made some more even more suggestive remarks. The guys led the way out to the car park with Mel in the middle and me tagging along behind. There was a lot of groping her tits and squeezing her ass which she enjoyed and. I go up to take a shower I’m in the master bath and Liz comes in and says why are you in my bathroom I have to get ready you will have to use the one in the spare bed room. I walk up behind her wrap my arms around her cup her big boobs, roll her nipples and kiss the side of her neck. Liz shakes me off pushes me away and says what the hell do you think you’re doing, I say showing my affection for my wife, Liz says that’s a laugh, I say what’s that susposed to mean. Liz says just get out so I can. After a few times I had to make the joke about " mooning me". She said , jokingly, she knew I loved her ass. I told her thats the kind of pics she should be sending to her BF. I never thought she would let me take the pics, but I offered anyway. She agreed to let me take pics of her ass with her thong sticking out, and another pic with her pants halfway down and her thong out as well. Luckily there is a back office, behind the front desk where noone has access to. While taking pics the phone.
