My wife Gillian broke her leg and as I work quite some way from home I was not able to get back at lunch times to help her. There was a young lad who we had gotten close to that lived three doors away and appeared to work from home. I asked him if he could drop in on Gillian at lunch times and see she had some lunch and drinks. He was quick to agree to help us out. We knew that she was to be in plaster for six weeks before they would have a look at her leg and see if it was then ok. Rick said that was no problem. The first week went well and Rick dropped in several times during the day, not just lunch times. Gillian told me that Rick had been very helpful, keeping her topped up with drinks and lunch. He even helped her to the toilet and back on several occasions. I told Gillian that after she gets out of plaster we must take Rick out for a meal as a thank you. Gillian agreed. The second week also went well, just four weeks to go. Then a few days into the third week I could see that Gillian looked a little flustered. She assured me it was nothing to worry about and I let it drop. The following evening Gillian was very quiet as if she was mulling something over. I inquired what was in her thoughts. She told me there was nothing in her thoughts. The next evening when I went into our bedroom I thought that I could smell the distinctive smell of sex. I thought that it couldn't be and dismissed it. The next night the smell in our bedroom was stronger. I now had suspicions that perhaps Rick wasn't quite the good Samaritan that I thought he was. The next day was Friday and work is always slow on a Friday, so I made arrangements for my work to be covered and left for home three hours early. On getting home instead of going straight indoors I slipped round to the back garden and looked into the lounge. Gillian was not in her chair and I could not see her anywhere. I slipped into the kitchen quietly. I could hear Gillian moaning loudly from upstairs. I ascended the stairs quietly. You got it. Rick was fucking the daylights out of my wife. I peered into the room through the partially opened door to see Gillian on her back and Rick straddled on top banging away at her pussy. Rick was talking to her as he fucked her. "I bet your not getting this from you husband," he asked, "Bet his cock isn't as big as mine." Gillian grunted in agreement. She wasn't wrong, whilst I have seven inches of cock, his was nearer to ten inches and way thicker. The grunts and groans from Gillian was testament to his size. Then Gillian was shaking. "Take that cock, take all of it and all my cum," he said as he then slammed into my wife and dumped his load into my wife's pussy. He rolled off her and lay groping Gillian's tits. "These tits are a waste on your husband. So is that pussy of yours," he surmised. Fortunately Gillian didn't answer him. They hadn't seen me. Then he was telling Gillian that he needed to get her dressed and cleaned up before her old man got home. I left the house and went for a drive, trying to make sense of what I had seen. I parked up in a carpark and sat there thinking, mulling over everything that I had seen. I had never suspected Gillian of being unfaithful and she had never given me any reason to suspect her of anything. I must have had my eyes shut, because when someone tapped on my window I jumped. "You all right," the woman asked. I told her I was. "OK. I thought that you might have been dead or something." I again assured her I was ok. As she walked away I drove away and went home. "Your home early," Gillian said. I told her that there was no work to speak of, so I slipped out early to get home to her. I looked at the clock. I was twenty minutes earlier than my normal time. I asked if she was ok. She told me she was and I went to make our dinner. The next week I wanted to know if it was a one of, so I took the Wednesday afternoon off. I parked at the far end of our road and sat watching the front door. I was there about forty minutes before I saw Rick walk down the road and into my house. I waited for ten minutes and then went and entered the house from the kitchen. Straight away I knew it wasn't a one off as I could hear Gillian moaning as he fucked my wife again. I again crept upstairs and this time the bedroom door was fully open. Gillian was face down on the bed and Rick was straddled her hips and banging that big thick cock in and out of my wife's pussy. "Do you like it this way? he asked. Gillian just groaned. When your back on your feet I will have to fuck you standing up," he told Gillian. The bastard intended to keep going even after she was ok again. "Take it," he said as he slammed in and out and stopped with his cock buried deep in Gillian's pussy. I guessed he had just cum in her. "Bet your old man cant do that," he said and then reached out to maul her tits. "Give me ten minutes and I'll fuck you again," he informed Gillian. He did as he said and fucked her again and she came twice before he dumped more of his cum into my wife's pussy. I left and drove around before finding myself parked up again at the same place as I had parked before. As I sat there, the same woman appeared and again came to my window. "Hello, you back, are you ok." she asked. I told her not really and she walked around he car and got in the passenger seat. "What's the matter?" she asked. I blurted out that my wife was being fucked by a younger man and worse still he has a huge cock. She was very sympathetic and asked did either of them know if I knew. I told her no. I explained that she had a broken leg and that he was meant to be there helping her, not fucking her. She asked if I was still having sex with her whilst her leg is broken. I told he of course not, she has enough with a broken leg, without me forcing myself on her. "Don't you think she might be missing your cock and that's why she has turned to this other man?" she asked. Her suggestion seemed to make sense and I told her so. Well go home and give her a good fucking," she suggested. I agreed and she left. I waited til my normal home time and went home. After dinner, when we went to bed I tried to get her warmed up by putting my hand between her legs. "Can't you wait until my legs better," she moaned. She wasn't missing my cock then. I went to sleep still trying to figure this out. I decided to wait until she had her plaster off and see what happens then. In the last week I was home five minutes early and almost caught them at it. Rick was helping Gillian down the stairs. "OK mate," he greeted, "Just helping her out," he informed me. I was thinking to myself, you just helped yourself to my wife's pussy. At the end of the week we were at the hospital and the plaster was off. The doctor told her it was all OK, but to take it steady for a few weeks. I was thinking that means no fucking with Rick. That night Gillian allowed me to make love with her. It felt so good. I pondered about telling her I knew about her and Rick, but bit my tongue. Gillian suggested that we take a week or so away. I agreed and took two weeks off work ad as we decided that flying was probably not a good idea just yet we went on a cruise. It was a fantastic holiday and Gillian fucked me most nights riding me instead of me fucking her. It was the best and the most sex I'd had in a long time On the last night of our holiday she looked down and I asked what the problem was. She didn't want to go home for some reason. Then Gillian blurted it all out. When I had told Rick to take care of her, he had taken it to it's extreme and took care of her sexual needs as well as all the other needs. She hadn't wanted it. but he pestered her. In the third week she had to go to the toilet and as she tried to stand afterwards and wipe herself she slipped and ended up on the floor. Rick came to her assistance and wiped her pussy. But he didn't leave things there, he then stooped and licked her pussy. She came quite violently as no other man had touched her there in twenty plus years. Before she knew what was happening he had his cock in her and was fucking her until he came. She had thought it was her own fault and would be a one off. The next day he told her that he liked her pussy and was going to have some more. She tried to tell him no, but he told her that he would tell her husband that she initiated it. Being scared that he would tell me, she let him have his way with her every day and sometimes twice in a day. She also pointed out that there was nobody else to help her during the day. She said that he had a huge cock and said she was sorry that it felt so good in her although she really didn't want it in her. Then she said that he is threatening to came around once we are home and continue to fuck her. I told her that wouldn't happen and I would sort it out. As soon as we got home I rang into work and told them we came home to a problem and I needed an additional day to sort it out. Then I left home at the normal time. I crept back over fences and gardens to get to my back garden and went into the kitchen and then upstairs into the bedroom to wait. I didn't have to wait long before I heard the front door go. He still had our door key. I heard Gillian telling him that it had to stop. I heard him tell her that he had told her that he intended to fuck her standing up and today was going to be the day they do it. She told him that they could get caught downstairs. Then I heard him bringing Gillian upstairs. I was behind hidden the bedroom door. As they approached the bedroom I heard him say the he had missed Gillian's tits. Then they walked into the bedroom. Gillian already had her tits hanging out of her top. His back was towards me as I landed the first and second blows. Then he was on the floor holding his head. I took the opportunity to walk around the front and kick him in the balls. He yelped and then groaned at the kick. He was holding his cock that was already out of his pants. I told him that If I ever saw him again this beating would seem like a small smack as I rained another blow onto his back with my padded cricket bat. I warned him that he had three days to leave our road or I would come looking for him. I turned his pockets out and retrieved our key. Then I dragged him down the stairs by his hair and threw him out into the road with his cock still hanging out. On getting back to Gillian she had put her tits away. She said she was relieved that I had taken care of the problem. That night in bed she again admitted that his cock was big and did feel very good inside her. I told her that if she wanted a big cock we would find one for her, but nobody was forcing himself on my wife and fuck her. We made love that night that lasted a lot longer than our usual quick shag. Three days later I went to Rick's house. I didn't know he was married, but he was. His wife had no idea where he was. She said he had come home, filled a suitcase and fled. I told her that he had been fucking my wife. She said that makes sense, and that if he ever came back she would beat his arse. A few days later my wife asked when and where were we going to find this big cock.
