Since my wife promised to do anything for me after admitting fucking two old boyfriends she has never refused to do anything I asked. I now asked her if tonight when our two mates came over for a meal if she would try and entice them into a swap. You want to see me fucked by John she asked. Not so much as I want to fuck Mary and hopefully you will also lick my cum out of well-fucked pussie. So here we were sitting in the lounge having after dinner drinks when my wife turned the conversation round to sex. She said I can’t seem to get enough these days and usually frig myself off during the day before fucking Ken as soon as he gets home. John said lucky Ken, Mary is strictly a bed at night person, to which Mary replied, I could easily change. Marg my wife said would you like more John, I could oblige if you like, has he a big cock Mary. Mary said big enough but I haven’t seen many to compare his with. Ken is 9 inches long and about 6 inched in circumference said Marg, lets see if John measures up, she then when over and sat on Johns knee, slid down between his legs and knelt between his legs before taking hold of his belt and beginning to open his trousers, Mary said I better see if Ken’s is as big as you say and came over to me. Only fair I said. John now had a huge smile on his face and he let out a little groan as Marg took hold of his cock and pulled it out. Oh look Ken she said a foreskin it’s a while since I have seen one of those and she peeled it back John wasn’t fully hard yet so she started to wank him. Mary now looked shocked and I felt the moment was going to pass so I undid my trousers and said here Mary one hard cock no foreskin as I set my cock free. Mary said I have never seen a circumcised cock before it looks good. It also feels good I said and took her hand and led it to my hard-on. She gripped it firmly and started to wank me. John now said I would love to give your wife a tity fuck, to which I replied Marg give him his wish. Marg stood up and pulled off her top and then her bra her big tits hung down with the nipples hard and she said do you like these John, a stifled yes escaped his mouth and Marg started to give him a titty wank. I took hold of Mary and said what would you like and then kissed her. She was hesitant at first but son became willing, I moved my hand on to her little tit and started to feel she tensed so I kept kissing, her hand was still wanking me slowly I moved my hand to her leg and up to her crotch on top of her trousers and rubbed her mound, she kissed harder< I began to open her trousers and she stood and said fuck this I need shagging and pulled off all her clothes, Marg did the same, then John and I joined them nude. Mary had a lovely body with firm little tits with long hard nipples, Marg now lowered herself down on Johns cock and started to ride him, I pushed Mary down on to the couch opened her legs wide and started to lick her wet cunt, she squirmed and moaned for about 30 seconds before shouting out, oh fuck yes yes yes lick my hole I’m cuming. I licked until she finished and then got up and placed my cock at the entrance to her lovely hot cunt, my wife was riding John frantically now and I knew from her groans she was near climax. Push a finger in her ass John that will send her over the edge I said, John obliged and Marg had a huge cum. She slid off Johns cock and lay back smiling, give Mary that hard cock she looks like she needs it, she said. I slid my cock into Mary and it felt great, I fucked her slowly at first till she started to cum again and then speeded up till it was over I then just kept my whole cock inside her and moved against her clit, till she came again then I fucked her hard till I shot my load deep inside her lovely hot wet silky hole. As I rolled off I said Marg loves my cum so can she lick it out of your pussie Mary, to which Mary just opened her legs and pulled open her hole and said yes please. We had a great night of sex, I fucked Mary again and Marg got it up the ass from John while she sucked my cock. Before leaving Mary said we will have to do this again I have loved every minute and will never be the same again.
