We managed to get the three kids out for the night and we were going out for a drink and a meal to have some time for ourselves. M has a great body and she was wearing he 1920's flapper dress which came down to just above her knees showing some fine leg. She wore her silver sparkly high heeled shoes and looked great. She was not wearing a bra so when she bent over, she revealed her petite 32B breasts and wore her red thong. She never normally wore this type of outfit and I knew that she was wearing it for me and when we got back, I knew that we would have a great time together. We went into town and had a great meal together and had a glass of wine. She is not a big drinker and I could tell that it had gone to her head. We left the restaurant and I noticed the looks she was getting from a few of the men in there and it did turn me on. I do have a real kink about M having sex with another man. She is very much against it so I do not mention it any more. We went to a pub and you immediately knew that she attracted attention. Not bad for a 38 year old woman. I was getting very stiff at this point and M was conscious of the looks. Although she did tease me a bit by adding that extra wiggle to her walk. As she was walking to the bar with that extra wiggle, I noticed that a tall black man wearing a tight T shirt was burning his eyes into her. Just a M turned to look at me she glanced towards the bar and saw this man looking at her and for a moment their eyes locked into each other. I could tell that M was attracted to this man by the way she blushed when she looked away from him and back to me. You could also feel the atmposphere between them. I raised my eyebrow and she smiled. I looked at the black man and he was also smiling. I think he had decided what he wanted and it was M. We had a glass of wine and M was looking a bit rosy cheeked at this point and she asked me for a dance. We got up to dance a slow dance and we kissed passionately. We sat down after the dance, my cock very hard at this point wanting to get her back home. We decided that after a wee we would leave and get back home and make the most of having the home to ourselves. When I came out, theblack man was talking to M and I could see she was breathing hard. He was looking directly down the top of her dress attempting to glimpse her breasts. I noticed that she was leaning forwards a bit to create some exposure for him to see. Anyway, I walked up a bit apprehensive and the guy introduced himself to me as David and he would like to ask M for a dance. I looked at her and she at me and I said that we were ready to leave but if M wanted to dance I did not have a problem with it. M a bit too readily said she would like to. He took her by the hand and led her to the dance floor, his eyes boring into her and I could sense what he wanted. As they got to the dance floor the DJ put on a slow song and I could see M and David pull each other close. She looked into his eyes and smiled and then she looked at me and winked, blowing me a kiss. She cuddled into the muscle of David’s chest and he moved his hands slowly up and down M’s back. I could see her mouth moving and imagined her softly moaning with the sexual tension between them. She moved her hands down to David’s bum and rubbed her fingers into his tight flesh. Her mouth opening at the taughtness of the cheeks. His hands had moved around to her bottom and he was rubbing her cheeks together and I could see that she was really beginning to lose herself with this man and I was almost bursting at the pants!! She moved back and looked up at David and their eyes locked. He leaned down and put his lips to hers and they began to kiss. Lightly and tenderly at first, then with increasing passion. I could see tongues between them and noticed that a couple of people close by were watching the passionate antics of my wife in the arms of this strange man. When the dance had finished they clung onto each other and walked over to where I was sitting. M’s make-up looking a bit the worse for the kissing. David apologised and said that he had got carried away with the mood of the moment. M just looked at me and asked if David could come home with us and she smiled at me and said I will fulfil your fantasy for you. I nearly dropped on the floor there and then. M was asking me to take this man into our home and then get adult with him. I said that it would be fine with me but there were to be a few rules. If M said stop, he would stop and leave. He was not to cum in her as she was not on the pill. She did not did not do pain or anal, but she would guide him. David was fine with this and M said that she felt nervous. I said that I would get the drinks and leave them to get to know each other for a bit. I walked up to the bar pondering what was about to happen. My shy wife, not interested in threesomes with men or women was about to give herself to another man. Phew, what a night this would be. I order the drinks and returned to the table. Davids hand was on M’s leg stroking her inner thigh and M was totally absorbed in what David was doing and saying that she did not notice my return. I was a little put out by this but took it to be part of the way things were going. Just as I put the drinks down I heard M groan with pleasure and saw his hand brush across her vagina over the dress. She reached her arm round his neck and leaned him forwards and kissed him passionately on the lips and whispered to him “Take me home and fuck me so hard that I will not be able to walk, you black stallion”. I was stunned M had never used this language with me before and I was beginning to get a bit jealous. Her free hand was now moving over his jeans to stroke the huge bulge there and she gasped when she touched it saying will it hurt, as she has never had a cock so big before. She then noticed I was standing there and looked at me apologetically. David’s hand now brushing her breast and she biting her lower lips in pleasure. Can we all go home she said, I need to get going or I will just burst. She reached up and kissed me gently on the lips and said that this was going to be a special night. I went to hail a cab and we all got in, me in the front and David and M in the back. I could hear them kissing and whispering to each other and was getting embarrassed. I spoke with the cab driver and said I was her brother and she was with her boyfriend. He just looked at me and said nothing. When the driver pulled up, one of M’s breasts was on display and the smell of her sex was dominating the cab. I noticed that David’s zip was down and could swear that I saw his brown head glistening. M did not bother to cover up her naked breast, instead she leaped out of the cab and David looked at me and put a dripping wet finger in his mouth and said “Mmmmm, that tastes good”. He smiled at me and put a tenner in my hand. I paid the cabby, and he drove away, by this time, M and David were all over each other, she just barely ably to the door searching for her keys in her handbag and David reaching round behind her rubbing her vagina with his hands. They both looked at me and M waved and blew a kiss. Motioning for me to open the front door. I rushed up to open the door as I did not want the neighbours to witness this. Even though I was so turned on, I was dripping, I wanted this to be our moment. I opend the door and David and M pushed passed me into the living room. I noticed that one of the straps had broken on M’s dress and was exposing one of her breasts. This must have happened in the cab. I locked the front door and put out the light and came into the living room and almost bumped into M leaning over the back of the setee and David rubbing my wifes vagina with his huge black cock. The head was glistening and she was groaning with pleasure telling him to push it into her. Her dress was pushed up to her waist and there was no thong. This must have been lost in the cab as well. M looked up and saw me, her eyes were moist with pleasure, she smiled and motioned for me to kiss her. As our lips touched I felt her push forward slightly and her mouth tighten. She released a groan like I had never heard and David said “Does that feel Good Mrs M? Kissing your husband as my huge cock enters your vagina?” She broke off her kiss with me and turned to her new lover and said that it was stretching her but the pain felt good with the pleasure of feeling this huge cock in her body. He said that he would push the rest of it in then. She looked at him as he gently eased his manhood into her. She braced herself against the setee and looked at me. I sat in front of my wife and saw the pain and pleasure etched on her face as David began his pushing and pulling motion. The repeat motions bouncing her small breast against the dress. David began to speed up and I saw him begin to sweat. M was really beginning to sweat and she bit her lower lip on more than one occasion. She looked me in the eyes and whispered “I love you” and just as she finished I heard David grunt with pleasure as he dumped his load deep into M’s sweating vagina. She looked at him in the eyes and he said that he would love to drill her vagina again, but this time in our bed. I said that I would be up for it, if M was and she very quickly said yes she was…
