We had been married for about 10 years M, my wife had been unemployed for four years. M was 34 at the time. To say she was prudish about sex would be an understatement. Before me she had never been with another man. Her sexual experiences were limited. Sex together was brilliant but she would never let her inner desires take over. It wasn't boring but nor was it exciting or adventurous. We needed some electrical work doing and on recommendation we called Phil. He had been in the trade for many years working for others but had recently started out on his own. I met him just the once during his initial evening visit to quote for the work. During the next month he visited three or four times to complete the work. Each time he visited M would tell me all about his visit, what a good worker he was and the jokes he told. To me he was ordinary looking guy in his mid to late fifties but for some reason M took a shine to him although despite my jesting that she had, she denied it and just insisted he was a nice chap. Some weeks after the work was finished he unexpectedly visited one afternoon. He explained that he was about to open a small unit on a business park just outside town which would be open to the public and needed someone to work in the shop and do general admin stuff for him and knowing M was looking for work wondered if she would be interested. She said to needed to discuss it through with me which she did but after a few days rang him and accepted. A few weeks later she started work. The unit consisted of a small public area where lighting and other electrical items were on display with two desks in. These two desks were opposite each other backing on the side walls. One was M's, the other Phil's when he was there. At the far end there was a door which led to a small kitchenette, toilet and store room. The first month or so was very slow with very few visitors and M would complain that a lot of the time she was bored with little to do. Phil was rarely there as he was out doing fitting but would pop in to collect things he needed. Again when she spoke of him it was obvious she had a thing for him. After about three months M was talking of her day and Phil came into the conversation. I again asked her if she fancied him. M initially denied it but eventually admitted she found him attractive even though he was at least 20 years her senior adding 'if I weren't a married woman'. Immediately I interjected, 'what's that got to do with it?. 'I'm married to you'. 'So what' I replied. 'I'm married' was the reply. 'So you don't want to fuck him then?....honestly?'. After a few moments of hesitation M admitted she would and that when we last fucked as I was entering her she was thinking of Phil. Then a few more truths emerged that whilst at work Phil was constantly flirting with her. Even cheekily asking what underwear she had on what she had worn for me at a weekend. M would play shy with him and tell him to stop but admitted this excited her and that the previous week they had had one of those moments when they almost kissed whilst standing in the kitchenette. This led to a lengthy discussion about marriage, faithfulness and sex My argument being that if she wanted some fun, so long as she was honest with me, it really didn't matter. This conversation ended with one of the best sex sessions we had ever had. For the next few weeks little changed except now M would openly tell me what had gone on with Phil. Nothing serious, just playful flirting, but as a result our sex life became more frequent and better. One night M told me that Phil had asked her to wear a skirt and stockings to work. Up till then she had worn casual trousers or long dresses with sandals. 'Cheeky sod' she said. 'Go for it, give the old man something to get excited about' I hopefully suggested. After another moral discussion M said she would think about it. The following Monday morning M was getting ready for work when she called to me for help from the bedroom. As I entered the room my heart began to pound. There on the bed was an assortment of underwear and coloured stockings. 'I'm wearing this skirt', she held up a grey pin striped knee length one, 'and I thought my black 4" heeled court shoe'. M pointed to the floor where there were four or five pairs of shoes including the black ones. 'what underwear and stockings do you think?' she asked. 'Your black bra and knickers with the red lace trim, those black stockings with the lacy tops' I pointed to the pair laid out so that the foot hung off the side of the bed, 'and a black suspender belt' I was actually suggesting what my wife should wear for someone else's pleasure! 'Thanks' M said in a very matter of fact way and she carried on getting dressed. I was in the kitchen when she appeared in the hallway, checking herself over in the hall mirror. Together with the aforementioned items she wore a plain red blouse. All in all very business like. 'What do you think?' she asked. 'Absolutely stunning' was my reply. Although M had a selection of underwear she rarely wore it and then it would only be after I had begged her to do so. Years of marriage had led to familiality. Why bother was the argument from M. But here was my prim and proper wife dressed up for another man. I panicked. Was I sure? Was she sure? What if she changed her mind but he forced her? Would she prefer him to me? Would I have M in the future? Christ what are we doing? As calmly as I could I put my fears to M. She too had doubts but described it as like being on a roller coaster for the first time going slowly up the first incline. Anticipation, fear, excitement,pleasure, all merging to form a stomach churning feeling but you know you have to go on. You can't stop. 'Are you going let him screw him?' I asked hesitantly. 'Maybe. I'm prepared'. M opened her bag and pulled out a pack of condoms something we hadn't used for years. 'Where did you get....'. M interupted 'I got them just after I started work'. With that she kissed me, said she loved me, picked her coat up and left for work. What a slut. She had clearly been preparing for sex for with Phil for weeks. Might not have planned it as such but. That day was one very long day. When M eventually got home she carried on as normal as if it were any other day. Talking about customers and sorting out the shop displays. Each time I tried to get eye to eye with her she ducked and dodged away. Eventually I cornered her against a wall in the kitchen and held her gently by her shoulders. Looking straight into her eyes I said 'come on, what's happened with Phil?'. 'Not a lot' she replied. 'What's that mean?' 'We were disturbed' M then explained that when reaching work that morning Phil was loading his van in a fluster and other than to say good morning had hardly noticed her. He then left. She described her disappointment that the man she was trying to please had ignored her. During the morning there were no customers and she had actually thought about locking up and coming home such was her disappointment but just after lunch Phil rang her. Initially he spoke about work but then made it perfectly clear he noticed her dress and would be back later in the afternoon to find out exactly what she was wearing. M had done her normal thing of telling him he would not. The afternoon went slowly but eventually Phil returned. M was sat at her desk. Phil took his coat off before sitting at his. There were no customers. Phil just sat staring at M. 'What?' she exclaimed. 'Are you?' he asked. 'Am I what?' was her innocent reply. 'Wearing what I asked for?. 'Thats for me to know...' Phil interrupted 'and for me to find out'. He pushed his chair back as far as it would go and lent forward peering under his desk so that he could see under M's desk. M squirmed a little in her chair. 'I think you are' he said in deep almost sinister voice. 'Show me' he demanded. M described herself as almost being mesmerised by his request and slowly pulled her skirt up to reveal her stockings. She moved her swivel chair slightly from side to side to allow Phil a greater view. At this point she was terrified not sure if she would go further. All the things we had spoke about earlier, all those 'what if's' came flooding to her. In these moments she was unaware that Phil had left his seat and was now stood next her. His groin at her head height. His hand moved slowly over his groin. It was clear he had an erection. M moved back trying straighten her skirt but his hand darted out stopping her. His fingers searched slowly for the stocking tops. M thighs were closed like a vice. She was trembling like some cornered meek animal.'Relax, just relax' said Phil. M was under his spell and she did as he said her legs weakened and her thighs opened slowly allowing Phil's hand to slide her skirt up so her knickers were on display. His fingers began to search for her opening as M fell further back in chair, legs slowly spreading. With his other hand Phil had begun to unzip himself.'Not here' spluttered M, 'someone might come in'. With that Phil grabbed her hand and led her to the kitchenette. Once there he held her against the sink and the two fell into a passionate kissing embrace. Phil's tongue pushed ever deeper into M's mouth. She was powerless and described an uncontrollable urge to fuck with this man. Phil undid her blouse and a hand slowly moved in clasping one of her breasts. He moved her bra cup down releasing her breast. Immediately his mouth was there suckling on her tit like a starved piglet. The zip to her skirt was next to go and her skirt fell to the floor. M jostled it with her feet and kicked it away. Phil was by now panting like a wild animal. Caressing was not the order of the day. He stopped sucking on her tit and stood back as if admiring his prey, my stocking clad wife in barely her underwear. Then his right hand thrust into my wife's knickers, his fingers plunged between her pussy lips. First moving back and forth. M was soaked and ready to cum there and then. One finger, then two entered her. M began to motion up and down forcing his fingers further in. His hand stopped and Phil pulled away, taking a step back. Both were panting heavily. He released his belt buckle, opened a button and pulled his zip down. His bulge was there. Nothing was said. M stepped forward and wriggled his trousers down off his hips. She then for the first time felt the bulge in his underwear. Rubbing slowly at first she could feel it growing. Her hand then went inside and same rubbing continued until the swelling left no more room. She pulled his erection free and began to move her hand back and forth along it's shaft. It was a good seven to eight inches with an incredible girth. Similar to the head of a baseball bat she described. With this his hand moved back to her pussy and the two began to kiss and mutually masturbate one another. This went on for a few minutes and the pair had discussed where they would fuck. There was no room to lie down in any of the back rooms. With a jesty voice Phil had said 'might just have to bend over the sink' when the shop door buzzer rang. Someone had entered. Both froze. Then giggled and rapidly got dressed. Phil was first to finish and calmly walked out into the shop to deal with the customer with the worst timing in the world. By now my fingers were inside my wife's knickers, which were still damp from her earlier experience, 'Fuck me' she almost screamed. I took her hand and began to walk towards the hallway and stairs. 'No, No' she cried as she pulled me towards the sink. Once there she lent forward and lifted her skirt up so that it lay on her back. I was wrestling with my trousers desperate to release my erection and do as my wife demanded. 'The blinds are open. Someone might see' I panted. 'So what. I don't care. Just fuck me...now'.
