I settled down for my long journey home from my business meeting in Scotland it would take nearly 5 hours to get back to King's Cross station I sat down and started to read some of the paperwork I had from my meeting. I was also thinking of my husband Mark who would be waiting for me there to drive me home. The train moved off as a tall good looking man asked if anyone was sitting on the seat facing me I said no. He sat down looking at me saying what a day I have had and having to wait an hour because of the delay just rounded it off. I was reading the papers but as I looked over the top of them I could see the bloke looking at me and smiling. I smiled back thinking how nice he smile was. He started to talk to me and soon we were chatting away. The journey seemed to past quickly until we got just outside York. The first class carriage was now empty apart from us two. When the train suddenly ground to a halt the power had cut out and we were now in total darkness. The driver told us all to sit tight as he radioed ahead letting them know what had happened. Moments later I felt the bloke sitting facing me running his foot up and down my leg, at first I moved my leg away but then I felt his hands on my knees slowly parting them. For some reason I could stop myself from letting him continue as he opened my legs wider. His hands moved up my legs opening my wrap round skirt as I felt his hand reach the top of my stockings. He eased my small white lacy panties to one side as his finger found my clit and slowly started to rub it. I eased myself back into my seat arching my back letting him have more access to my pussy that was getting wetter by the moment. It was them I felt him tongue moving up my thigh as soon replacing his finger on my clit. I held his head as his tongue went to work on my clit. Soon he was probing deep inside my pussy as I opened my legs as wide as they would go. Here I was a married woman who had only every let two man near my pussy now letting a total stranger finger and lick my cunt. I started to shake as I felt the biggest climax of my life. I had cum hard over his tongue which he seemed to enjoy as he continued to lick me clean. Then he stood up and I heard him undoing the zip to his trousers. Gently he eased my head forward and I felt his hard erection touch my face, I reached out and gently rubbed his prick which felt much bigger and thicker than my husband's. He eased my head forward a little more as I opened my mouth taking as much of his cock as I could. I felt the tip touching the back of my throat and there was still a good 2 inches still to go before I had it all in my mouth, I decided to go for it and took it all very deep throat as I moved my head back and forth caressing his hanging heavy balls as I started to mouth fuck him as had me moments earlier. The driver announced that it could be another half an hour before help arrived I thought good as I really went for it pulling the strangers foreskin back as I licked the top of his cock tasting his pre-cum. He pulled back whispering he didn't want to cum in my mouth. He moved back to his knees easing me forward on my seat as I moved backwards knowing he was about to fuck me. We positioned ourselves so my pussy was level with his cock as I felt the tip touching the entrance to my pussy. With a gentle thrust forward he entered me as I bit my bottom lip so not to scream out with pleasure as he pushed every inch deeply into my willing pussy. We slowly rocked our hips in perfect timing as we started to fuck each other. He leant forward and we kissed. We started to move a little faster as I whispered please be careful I'm unprotected. He said don't worry as he kissed me again moving his cock harder and faster into my pussy. I placed my arms round his neck our tongues dancing inside our mouths as I rocked my hips meeting his thrusts our skin slapping together as he cock slammed home deep inside me. Soon he whispered I'm cumin were do you want it you little slut. I whispered back fuck me you bastard knock me up. With one last very hard thrust I felt his cum shooting deep inside my pussy. We kissed until I felt his cock go limp and slip from me. 5 mins later the driver said help was here. We were put on another train and for the rest of the journey I felt the strangers cum dribbling from my pussy. We got to King's Cross and hour later. I saw my husband at the end of the platform, we kissed when he told me he was trying to call me but I wouldn't answer. I told him I didn't hear the phone which seemed to keep him happy. Once in the car I told him how I had been a good little for slut for him and how I had been fucked on the train by a total stranger. He smiled saying how pleased he was with me and continued asking if I let the stranger spunk my unprotected pussy I told him I had and that hopefully he had made me pregnant. Mark wanted me to be his dirty wife slut and let another man knock me up. That night we fucked hard with Mark telling me what a good slut I had been as he could fill my pussy was full of cum and hopefully the stranger had fucked his baby into me. This happened a month ago and I have found out I'm not pregnant which we are both upset about. I am going away again next week for work but have to stay overnight so I will be out to try again for him.
