It was eighteen months or so after the birth of our fourth child, a daughter as it happened; having three boys already the wife was over the moon to at last have the girl we had longed for. We had always had a reasonable sex life Janice never ever instigating the sex but would always enjoy. Not really wishing to be adventurous, and would not always reach a climax no matter what I did to pleasure her. However after the birth of our daughter there was the usual lack of interest in sex, which lasted for ages this time. Then there a change in her which I liked but could not understand what had brought about this change in her. She started to dress the way she had when we were in are courting years, shorts skirts, low cut tops and stockings, even to wearing thongs instead of the normal full briefs which had become the norm. After several months of this it became noticeable that during are usual sex sessions she seemed more responsive and even more readily started to reach a orgasm, it was great having her climax but now my mind was doing overtime as to why this new pattern to her sex life and her dress code in general. I set about finding why the change had occurred, it wasn’t until I had to return home from work unexpectedly one morning that on entering the house I could hear talking in the lounge. I believed it was a lady friend of the wife having a mid morning cuppa, I went through to the kitchen to get my lunch bag which I’d forgot that morning. It was when I was walking back through the hallway I was a little taken aback to hear it was a man chatting with her in the lounge. I entered the lounge to see the wife and Jack sat on the settee with a drink, Jack had plastered our bathroom walls for us several months earlier, and I found it strange to see him there, anyhow I had to get back to work so said bye to them and left. That evening whilst were in bed I asked how come Jack had been there earlier that day, she said he was working along the road and had popped along for a chat, and I left it at that but my suspicions was aroused. Over the next passing months I would find reasons to go home at odd times of the day, and more often than not jack would be there chatting or having a drink Over the next few times we had sex I would ask her was she having an affair with Jack and was he fucking her, I got a stern reply, certainly not. Several months later whilst fucking her and I had been constantly pushing her about Jack she confessed that he had been fucking her for the last six months or so. I was completely stunned by this I know I thought it was going on but to be told I was right hit me hard, until then I was the only one to have ever fucked her. I was bitterly jealous that someone else had fucked her, but at the same time found myself getting aroused by the thought of her being taken by another guy. After that every occasion I got I would pressure her of details of how it came about that she let him fuck her. After ages of me asking her she promised to tell me if I stopped going on about it. That night as she lay next to me stroking my cock she told me how it had came about. Whilst he and a labourer plastered our bathroom, she being rather tidy had spent several days making sure the room was cleared etc. however after they had been there awhile she asked if they would like a drink. The labourer being a smoker went outside for a smoke leaving them together after a few moments of being alone Jack reach in his pocked and said these must be yours I presume pulling out a pair of her knickers which he had found behind the radiator when he removed it. With that she grabbed Them and made a quick exit, and he got back to work, she told me it was a couple of hours or so before she showed her face again. At lunch time he said sorry if I embarrassed you earlier that was not the intention. She made him a drink and sat and chatting, during which he kept paying her compliments like how great her figure was having had four kids. He kept flirting with her most that afternoon while his mate was out mixing plaster. When the days work was done he said he would be back the next day at 8:30 and as he walked passed her to leave gave her a kiss on the cheek. Next morning he arrived on his own with no mate. Janice said she was rather nervous when he knocked on the door due to the way he had left the previous day. About 10 she asked if he would like a drink and when it was ready said she would take it into the lounge where it be more comfortable. She sat down and got all excited when he chose to sit next to her. After a little while paying her more compliments on her looks he lent over towards her turned her head and kissed her full on the lips. She told me that at first she went to pull away, but the hand that had turned her head held her there. And she responded to his kiss, then the hand that held her head lowered until it rested on her right tit, held it there a moment and then started to caress it, at this point she told me was trembling with excitement, with the attention this man was giving her. The hand on her tit than travelled down her body and rested on the top of her thigh and lingered there and with Janice giving no resistance started to pull her skirt up to the top of her legs. His hand went up her skirt and rubbed her pussy through her tights and knickers. She dropped her head onto the back the settee and closed her eyes and found herself pushing onto his hand. After a while she felt hi getting up and thinking someone must be about went to get up as well Jack so no stay there, the next she knew he was knelt in front of her put both hands up her skirt to the waist band and proceeded to remove her tights and panties in one motion aided n by Janice lifting her bum up. He probed her pussy lips and then parted them and entered two fingers into her and finger fucked her with a passion until she climaxed. He said I hope you enjoyed that and still recovering mumbled a yes I did thank you. He helped her get tidied up and returned to job in the bathroom. I asked her was that it, and she said yes at that time but there were several more other encounters over the next few months but that’s another story.
