Jenny and I were saving to get married and I was fed up with being permanently broke. Also we struggled to get time alone and as you can imaging a pair of twenty year olds have needs. It was Friday night and I was on my way to collect Jenny for the evening. When I got to her house she said she had a surprise for me, we were babysitting for family friends. I wasn't keen, but then the upsides were that once the kids were asleep we could have time together and we weren't spending money and in fact Jenny would be paid for her time. I had never met Marsha before and when we arrived she was running around getting ready. She was very sexy looking and dressed to kill. What did seemed to be missing was her husband. She was giving instructions to Jenny and then a car horn was going and she was out the door like a rocket. After she had gone Jenny was also a little confused as the car driver was not her husband. The kids were more fun than I expected and come nine o'clock they both went off to bed and were quite quickly asleep. Now was our time and it wasn't long before I had Jenny naked and we were going at it on the sofa. Then the phone rang and Jenny answered it. It was Marsha asking if we could stay later as she was enjoying herself. Jenny told her to stay as long as she liked. I'm not sure what was said, but Jenny gave a chuckle and agreed. When she got off the phone she informed me that Marsha would not be back until after midnight. She had also guessed that we were making the best of our time together and had suggested that we make use of the spare bed. It wasn't long before we were making the best of her spare bed and Jenny was getting the best pounding I could give her. Using a bed was a real treat for us, it was normally the back seats of my car so we were making good use of it. Afterwards we lay dozing. Jenny had fallen asleep when I heard Marsha arrive home. I got up and looked out the window and saw her outside the car kissing a different man to the one she left with. I got dressed and went down stairs so that I wasn't caught with Jenny in bed. When Marsha came in doors she was a little surprised to see me and I was surprised to see the state she was in. There was no question in my mind she had been shagged silly. Her disheveled state and the fact that she was not wearing the stockings or tights she went out in. She asked where Jenny was and I told her in the spare room asleep. Looking at Marsha she looked even hornier than she had when she was getting ready to go out, and knowing what she had probably been up to gave me a lump in my trousers. Marsha turned a couple of table lamps on low and turned off the main lights and then she jumped me. Hands everywhere, her tongue was down my throat and she was trying to get my trousers off. I said, "What about Jenny?" Marsha replied well she can join in too if you like, but wold prefer it to be just the two of us. Then my cock was out and Marsha was on her knees sucking like I had never been sucked before. I had never had a girlfriend that could deep throat me or would try. I came pretty quickly and Marsh swallowed my load and then said that she would get me ready for the main event. The finger up my arse was something I had never experienced before. Marsha soon had my cock standing to attention again. Marsha knelt on all fours on the sofa and raised her skirt. Not only were the tights or stockings missing, so were any panties she might had been wearing. I had the slightest twinge of guilt over what I was about to do and that Jenny was asleep upstairs. Then when Marsh ordered me to hurry up and put it in, I forgot about Jenny and did as Marsh ordered and slipped my cock in. Not as tight as Jenny, but very smooth and slippery. It then dawned on me that I was sliding in someone elses cum. To late to worry about that now as Marsha was throwing her arse back at each thrust I made. I reached around for a handful of tits. She was much better blessed that Jenny, probably as a result of having two children. We must have fucked for a good twenty minutes before Marsha groaned through her orgasm and I followed adding to her cum filled pussy with what little I had left. Marsha wanted me to go with her to her bedroom. I assumed for further sex, but I was worried about getting caught by her kids or worse Jenny. I told her that I couldn't, so she insisted that I come around one evening in the week, I quickly agreed. Marsha went off to bed leaving me sat on the sofa thinking about what had just happened. What I did know was that I had enjoyed the thrill of secretly fucking someones sexy wife with my girlfriend totally unaware of what I had done. Needless to say that Thursday night I was back around Marsha's house, without Jenny, and in Marsha's bed. This woman was insatiable and had a sex appetite that would have served three women not just the one. I went home totally knackered. It became a regular thing when her husband was a way on work I would sneak around and get the fucking of my life. Jenny and I were still doing the odd babysitting for her and every time she came home, she looked like she had been well and truly shagged, on a few of those occasions I added to the cum already inside her. One evening whilst Jenny was sleeping upstairs and I had just added to Marsha's hungry pussy we sat talking and I asked her where she had been for the evening and she was quite open and told me that she had been to a swingers club. I asked about her husband and she said that he knew where she was and when he was home he would go there with her. I was stunned. She went on to explain that he was sixteen years older than her and had a low libido. To keep her satisfied he started taking her to the swingers club and whilst he might make use of an odd woman as he was there, Marsh ran wild fucking and sucking her way through any man she could. This was making my cock grow again trying to visualize Marsha with many men. Then she told me that he was fully aware that she had seduced me and was having a top up, as she put it, with me. On one Thursday night I turned up to have a regular session with Marsha. I was shocked to hell when Ben opened the door and welcomed me in. What husband welcomes his wife's lover into the house with open arms? Anyway he informed me that Marsh was getting ready and would be down any minute. He asked what I drank and I told him a whisky. I couldn't normally afford one and would have had a beer, but as I wasn't paying I asked for a whisky. Ben poured two large whisky's and handed me one. "So your the young lad that been fucking my wife for several months now?" he asked. I told him I was. "Well tonight I'm going to just watch as you fuck my Marsha," he informed me just before she entered the room. I must have stood there with my eyes wide open and tongue hanging out. Marsha was dressed in a leather bra that had her full breasts hanging out large cut outs and a leather skirt that barely covered her arse and fanny. "Well go on man, give it to her," Ben insisted. I took out my cock that was straining at my jeans and offered it to Marsha who was quick to get on her knees and start sucking me. Ben retired to an arm chair and just sat watching. He was really cool with this, so I grabbed myself an handful of her tits and massaged the nipples. Ben enjoyed that and told me that Marsha loved her nipples pulled quite hard. I did as he suggested and I heard a groan escape her mouth, even if it was muffled by my cock. Then Marsh suddenly pulled me down onto the carpet with her, and turned around and planted her naked pussy in my face as she went back to sucking my cock. I started to lick her pussy out only to get a mouthful of cream. I wasn't the first man to be at Marsh's pussy this evening and she already had at least one load in her. It was another first for me as I had never sucked another man's load from a woman's pussy. It didn't taste bad so I just continued. I was beginning to get close and I guessed that Marsha knew as she suddenly got off me and pulled me to my feet. She pushed me to sit in another chair as she straddled me facing away and towards her husband. She held my cock upright and just between her pussy lips, "Ready Ben?" she asked her husband. He said he was and Marsha slowly sand down penetrating herself on my cock. When it was all in she sat there for a few moments and then started to ride me. Her hands had moved backwards to help support herself and to give Ben a fully uninterrupted view of her pussy as she rode me. Then she started a dialogue with Ben telling him how deep I was and how good it felt and who's cocks it was better than. I wasn't a party to this conversation and just kept pushing up to meet Marsha's pussy as it lowered onto my cock time and time again. I remembered that Marsh loved her nipples treated a little rough and reached around and grabbed both of them and pulled, twisted and squeezed her nipples. Not only did Marsha come, but she kept coming again and again. The harder I pinched her nipples the longer and deeper she seemed to come. I could see the huge grin on Ben's face as she came yet again. Then he was on his hands and knees between both our legs and he was licking at Marsha's pussy and clit sending her over the top even more. Marsha came like a train at full speed. it triggered my own orgasm and as I came Ben pulled my cock from Marsha's pussy and sucked the cum from my cock. Another first for me. Later I fucked Marsha again in front of Ben. He was cheering me on as I fucked her doggy style. As soon as I had come in her Ben was between her legs sucking my come from her pussy. My affair with Marsha continued with or without Ben being present. Then one evening I arrived to enjoy another session with Marsha to find that Ben was there but Marsha wasn't. Initially I was worried that Ben wanted a gay session with me, and although I had allowed him so suck cum from me and I had licked others cum from Marsha, I wasn't into a real gay session. Ben put my mind at ease telling me that Marsha was running a little late as she had been out shopping for for some clothes. We sat talking drinking his whisky. Ben asked why I was fucking his wife instead of my girlfriend. I told him it was the thrill of being with someone I shouldn't be with. He suggested that perhaps a foursome sometime with Jenny. I told him that Jenny was so straight laced that it would end my relationship with her just for suggesting the idea. He asked why I hadn't married Jenny yet and I told him we were still saving up for a deposit for a house. Then after a few moments of thought he said that he had a proposition for me. I sat intrigued as he said that he would give us the deposit if I continued to screw his wife on a regular basis and let him watch whenever he was home. Ben was hiring me as a gigolo at the cost of a deposit for a house. It was a deal I couldn't refuse. I was fucking his wife anyway and he had watched us several times, so making it more regular was no problem. Jenny and I moved into our new home and got married. The night before I was married I spent it in Marsha's bed with Ben watching as I pounded his wife. The affair went on for almost twenty five years and then Marsh slowly stopped wanting sex. For the next two years Ben brought in different women for me to fuck while he watched. Then it all came to an end when I think Ben gave up on sex. I never did tell Jenny where the deposit came from or what I had to do for it. Would I do it over again? Hell yes. Having a perfect wife and a fantastic lover. What man wouldn't if he thought he could get away with it.
