It was Christmas time four years ago. Beth my girlfriend had moved into my flat just two months back. Whilst I loved her very much, as they say you never know someone till you live with them, and now I did cracks in our relationship were growing. I already knew she was the spontaneous type before she moved in, but what I didn't know was that she left everything to the last second and was very untidy. I was constantly tidying up behind her and chasing her to be ready for work or when we were going out. We both had to work over Christmas, but had managed to get time off for new year and the following week. Beth wanted to go to Spain or somewhere hot and I had to keep reminding her that I had bills to pay and not an awful lot of money. At twenty four I had become more domesticated and settled into more of what society would call the norm, compared to when I was younger and all I was interested in was girls, Partying and surfing. Beth on the other hand was still in the phase that I had now grown out of. In the end I agreed to take Bessie my old VW campervan down to Cornwall for new year and the week. It was new years eve when I found a place to park up where I had often parked when I was going surfing. We wandered the town and found somewhere to eat and afterwards went out into the cool night and joined the mass of people milling around. It was now that I bumped into one of my old surfing buddies. He was telling me that a bunch of people were taking some booze down to the point and was going to watch the firework display from there and that Beth and I should join them. After stocking up on booze Beth and I made our way to the point and met up with about thirty other people. They were all around Beth and my ages. Beth was twenty one at the time. Someone had built a fairly large bonfire on the beach, but not lit it yet. We sat around talking and someone put some music on and some of them were dancing. I had spotted a young girl, probably in her early twenties who had what I thought was a boyfriend. She was extremely attractive and had the sort of stunning body that I love. Her boyfriend put a blanket on the ground and sat down and she pulled away from him and went where a group of people were dancing. I watched her body twist and shake an imagined what she could do for me between the sheets. Beth was also up dancing, Then the music was turned to the BBC where the countdown to the new year was happening and everyone was now on their feet and jumping around. I see someone hanging on to Beth and as the Bong signalling midnight sounded people everywhere were kissing and the man with Beth had his tongue down Beth's throat and the kiss was being reciprocated. I kissed several of the girls with kisses that were more like brother/sister kisses. Then I was stood near the young lady I had been watching. I positioned myself to be next in line with her. If Beth could have a snog so could I and as she turned to me I pushed my tongue into her mouth as we kissed and put my hands on her gorgeous arse and pulled her tight to me. She responded and kissed me back, swapping tongues and her hands went to the back of my head and also held me to her. We kissed for what felt like ages and when we broke off I introduced myself and she told me that everyone called her Kas. I spotted that her boyfriend was folding their blanket and walking away. I pointed that out to Kas and told her that I hoped I hadn't spoilt anything for her. She told me that it had done her a favor as he wasn't her boyfriend, he was a wannabe that she was struggling to get rid of. I looked around as the music had started playing again and Beth was nowhere to be seen. The fire had now been lit and we stood close to it watching the fire works. Kas said she was feeling a little chilly do I wrapped my arms around her as we watched the display. I was a good one and must have lasted around twenty minutes. Then a large group of the people there stripped off and ran into the sea. There was less than a dozen of us left by the fire and Beth was nowhere to be seen. Although the fire was hot as you moved a little further away the temperature soon dropped. Kas suggested that she knew an all night coffee shop that did excellent hot chocolate and that we should go and get one. We walked up the beach towards the roadway and as we got closer could first hear and then see several couples making out. Even before I saw her I could hear Beth giggling and then groaning. As we got closer I could see the man that had put his tongue down Beth's throat now had it in her fanny as Beth sucked his cock. My mind was made up that Beth just had to go, besides the cracks in our relationship as far as I knew this was the first time that she had cheated on me like this. A kiss was one thing, but sex was another altogether. As we walked up the roadway I suggested to Kas that I had drink making facilities in my camper and that we could go there instead. Kas agreed and soon we were drinking coffee and warming up as we sat huddled in my van. Kas finished her coffee and turned to me and kissed me again. This time it was even more passionate than the first kiss and her hands were roaming around my crutch as she kissed me. We broke for a moment and I suggested that we got a little more comfortable. Kas looked confused when I opened the sliding door and asked her to get out. Then she smiled as she watch me turn the seat into the bed position and throw the two duvets onto it along with pillows. Then we were back inside as I drew the curtains. By this time Kas was naked and between the two duvets. Seeing her laying there waiting for me had me as hard as a rock down there. Kas helped me undress and climb in with her. We lay kissing for some while with our hands stroking each other. Kas had a soft yet firm body and I wanted to enjoy every moment with her and not just rush things for a quick fuck as I would have done just a few years back. All thoughts of Beth had long since left along with any guilt or regrets. Eventually we needed to move on from just kissing and I slithered under the duvet and kissed my way down Kas's body taking my time with her tits and then her naval before kissing her shaven mound before landing on her pussy. She had a tight little pussy where the lips needed to be coaxed open to get to the treasure inside.After lots of kissing and licking, especially over her clitoris she was wide open and from the moaning was more than ready. As I started to move back up her body she grabbed me by my ears and pulled me up to be face to face with her. She kissed me as my cock slowly penetrated her pussy. It wasn't long before we were in a rocking motion as was the camper as we raced to our finale. Kas screamed her way through it as I dumped my load deep into her pussy. We lay together exhausted from our mutual loving. As we recovered Kas asked had I anything to drink and I put a light on and poured us some Vodka. It was now that Kas spotted some of Beth's clothes that again she had left lying around. Kas asked who they belonged to and I told her about Beth and that it was her that we saw as we left the beach. I also told her that our relationship ended when she cheated on me. A little later we made love again. This time it was slow and sensual and built up to an amazing spectacular explosion of passionate blissful feelings and emotions. We collapsed into a heap and were soon asleep. I woke when there was some revelers walking past singing. Kas was fast asleep. I snuggled tighter into her and dozed off again. In the morning Kas woke me as she stroked my cock. I had woken with a morning woody and Kas was soon trying to get as much of it as she could into her mouth. Whilst it wasn't the most experienced blow job I had ever had it was certainly up there with the most enthusiastic ones. I had to stop Kas as I was getting close and rolled her onto her front and kissed my way down from her head and neck to her buttocks then between them searching out my prize. Her flower soon opened to my tongue and she was moaning softly to herself as I lapped at her honey. Then she was telling me to get on and fuck her. I was soon on top and sliding my cock into her love hole. We lasted what felt like hours before Kas's pussy tightened around my cock, gripping it and forcing it to give up it's spoils. I came deep inside Kas's pussy. After recovering We dressed and straightened the campervan up and I was making us breakfast when Beth turned up with her new lover in tow. She looked less than happy at seeing Kes sat there drinking tea as I finished cooking breakfast. I handed Kes her plate and Beth asked if we could talk. We wandered away from the to talk. Beth was apologetic and expected me to be the same after seeing Kes. She seemed shocked when I told her that it was over as she had cheated on me. She blurted our that it was obvious that I had cheated on her also. I told her that I had and that she could take her stuff from the van and collect anything from the flat when I was home. There were tears, but I made it clear that I had made my mind up. She grabbed her stuff from the van and left with the man. I told Kes what had happened. She said she was sorry if she had caused any of the upset. I told her that it had been coming for a while. Kes stayed with me for two more nights in the van. I told her that in a few days time I would ave to go home, but I didn't want to leave her. She told me that there was nothing keeping her in Cornwall. So later that day after a long walk along the beach we went to her father's house. He seemed a very grumpy old sod and snapped at Kes asking where she had been. She ignored him and went and packed two suitcases with clothes and stuff. Then she told her father that she had enough of him and we left. By the end of the day Kes was unpacking her suitcases into drawers and cupboards in my flat and I was packing up Beth's stuff. Well as I told you that was four years ago and Beth collected her stuff a while later and Kes is still with me and she was the best new years present I could have had.
