If you have read parts one and two you will know that my wife cheated on me with John her best friends husband. Sandra admitted that she had cheated and forgave and she said it never happen again. We later moved to a semi detached house the neighbours were in their 50s. We got on well and were happy living in our new house. We had started watching porn which turned us on firstly just couple fucking each other the it graduated to cuckold porn This had an affect on me that i wanted my wife Sandra to be fucked by another man. She also was more vocal watching cuckold porn and seamed to have bigger orgasms. Sometime later Sandra told me that Mike our neighbour was chatting to her one day and when he went to leave he kissed her and pulled her into him. She admitted she could feel his cock against her and she responded and returned the kisses then came to he senses and pulled away when he said if you ever want a baby let me know. When we were in bed making love i asked Sandra if she wanted Mike to fuck her yes i want him i really want him. Then when we came back down it was a flat no i can not cheat on you again. I told her it would not be cheating i give you my blessing. I involved Mike in our fantasy and would say you want Mike don't you she would always respond yes yes i want him. I said to her go on then let him fuck you she said i couldn't,, yes you could,, no i couldn't even ask him if i wanted to. So we talked about it at length,, she was unsure and was afraid of how i would feel after it had happened. I told her i wanted this to happen so much and that i would love more than ever,, Sandra said if she did let him fuck she would have to be alone with him. I told her that's fine darling because i do not want to watch, but i want to hear all about afterwards She had now come round to accepting it would happen but it was up to me to arrange it and not make it look like she was wanting him. So one morning before going to work i sent Mike a message from Sandra phone asking if he could look at the toilet as it was not flushing properly. I then left for work and all day i was thinking if she and mike had actually been in bed together. This was making my heart race and my stomach churn and making my cock hard it was all that i could think about. On my return from work Sandra told me all about what had happened. My wife wants to write the next part which is fine by me as she wants to relate it first hand which i think that is the way it should be.
