So this happened many years ago, 1992 August sometime. My then young wife and I had been away for a few days to Scarborough, 6 hour coach trip on the national express from Liverpool, no car back then we'd only been married a month or so and decided a trip away would be good. We were both just in our twenties and very much in love and lust with each other, my wife was very highly sexed and when she was horny there was no stopping her, being pleasant on the eye didn't do any harm either as she definitely dressed to be looked at and admired. Nothing out of the ordinary happened while we were away, just good days and nights drinking eating fucking and doing what everyone does on holiday but the journey home was a different story. We'd been for a last walk around the town before catching the coach home and walked into a second hand bookshop browsing for something to read on the long journey back. Unknown to me Sonia my wife had picked up an erotic novel and bought it for me to read with her, the coach going back was pretty empty so we took the back seats and had them to ourselves, we settled down and began to read the book between us as the bus made its way through country lanes. Now this book was hard-core sex, a series of interviews with different women and men telling someone about their sexual fantasies and I could tell Sonia was getting turned on, she had her hand on my lap as we read and my cock was hard as stone, I placed my hand on her thigh to reciprocate lightly running my fingers on her warm skin, this continued for quite a while as we were totally engrossed in the book. The stories were very explicit and covered subjects we hadn't even thought of before nevermind discussed but as the journey progressed she would stop reading every now and again and ask me what I thought of some of the subjects mentioned and I'm talking threesomes incest beastiality bisexuality exhibitionism, every sexual perversity you can imagine. All the time this was going on she was holding my cock through my shorts and slid down the seat a little so her skirt which was short to begin with rode higher until I could see her knickers. After about an hours journey we pulled into York and a couple more passengers got on the coach, one a man in his late thirties maybe came down towards the back where we were sat but instead of sitting on the back seat with us took the seat just in front to our left, making us vulnerable to being seen should he look, so this caused Sonia to sit up straight again although she didn't straighten her skirt as much as I thought she would leaving a lot of thigh on show. The bus pulled away again and we continued on our journey, after a few minutes Sonia put the book between us again and said we should keep reading and who was I to disagree. Once again she would stop and discuss each story but in a more hushed tone so as not to be overheard by the man in front, who did occasionally glance over with a natural curiosity I suppose as people do on buses, although to be honest with the amount of leg Sonia was showing I couldn't blame him, the book was certainly having an effect on her as she put her hand back on my lap and gently rubbed my cock as we read again, only this time her other hand was stroking her own thighs as the stories became more intense. I knew she was getting hornier by the minute but had no idea just how much until we were reading one fantasy about a threesome between a woman and two men and she leant into me and asked had I thought of her being fucked by someone else as I was fucking her, I had to admit I had once or twice and this made her smile as she slowly hitched her skirt up a little once again revealing her knickers. We carried on reading and occasionally I would look up to see the man opposite stealing furtive glances obviously aware that we had something going on, Sonia totally oblivious to these looks had now undone a couple of buttons on her blouse and was stroking the top of her breasts as she read, her thighs which previously although showing a lot of skin were now slightly apart as my fingers traced there way to the top and brushed against the heat of her pussy causing an involuntary shudder and a quietish sigh. To say she was turned on was an understatement and was now rubbing my cock much more vigorously, undoing the button her hand slipped inside to hold it, I continued turning the pages as we read and once again glanced up to see the man no longer stealing looks but staring as best he could without looking obvious, by now I was taken over by a complete disregard for consequences and began to run my fingers over Sonia pussy lightly pressing the silky fabric into her slit. I knew that once she started she wouldn't stop until she had cum and if the devil was inside her who knew what would happen. This continued for a few minutes her with her hand on my cock slowly wanking it inside my shorts and me with my fingers stroking her pussy as the material gradually became wet from her juices, by now she had stopped reading and with her eyes closed and her head on my shoulder began whispering in my ear telling me how horny she was and how she wanted to suck my cock or any cock for that matter as the stories had really fired her imagination, as she was telling me this I had gently pulled her knickers to one side and began to spread the wetness of her pussy around her pussy lips, I don't think I'd ever felt her so wet before. Looking over at the man again I could see he had changed his position in his seat and was now staring directly at us, we had an audience and Sonia was unaware, now I had a bit of a dilemma, did I let this carry on and let us both get lost in each others sex or let her know we were being watched? Her hand had now pulled my shorts down so she had free access to my cock under my boxers and she was still whispering in my ear about all the things that had turned her on in the book, my fingers were now rubbing her clit and gently finding there way into her wet pussy as I told her we should calm it down as I thought we were being watched, Sonia moved her head back slightly opened her eyes a little and in the most sexiest huskiest voice said " I know". This was the point I thought fuck it if she's into it I'm into it and turned my face to hers and began a deep slow sensous kiss as our hands pleasured each other without a care in the world. What happened next floored me, without warning she took my cock out in full view of the now ardent spectator and leant forward taking it into her mouth, slowly she began giving me an amazing blow job knowing full well we were being watched, my cock pulsated with every downward stroke of her mouth her tongue lightly licking the tip as she came upwards, her head lost in my lap, my arm now went around her back and pulled her skirt up over her arse as the spectator became more engrossed in what was going on, my fingers found her knickers and pulled them to one side now giving our man an unobstructed view of Sonia's beautiful pussy and arse, she was now completely lost in her lust and even if someone had thrown a bucket of water over us I doubt she could have stopped. As she was sucking my cock I noticed she had begun looking at our watcher making eye contact and each time her head came up and her mouth wasn't on my cock she began to talk quietly but the words coming out of her mouth were the dirtiest I'd ever heard her speak, our man couldn't hear what she was saying but if he had he would have been sat next to us in a second, my fingers were now deep in her pussy and as she sucked she was moving her arse on them slowly and deliberately, she now decided to sit up and I thought oh she's come to her senses but I was wrong, she slid down a little in her seat spreading her legs and resting her feet on the footrest of the seat in front, her blouse was now open to the navel and she began to play with her tits underneath her bra as I began to once again slip my fingers around her soaking wet pussy. By now we had been driving for a good couple of hours and the sun was gone and the interior of the coach was getting darker by the minute, our voyeur now moved to the edge of his seat, literally now a foot away from where Sonia was happily on display. As she played with her breasts she moved the bra so our friend could see better, her nipples were standing out and firm as she gently rolled them through her fingers, my rubbing of Sonia's Clit was definitely building up to something as she suddenly tensed and let out an almost audible sigh from what was her first orgasm. I thought maybe once she'd cum that would be that but she told me later that it hadn't totally sent her over the edge. The interior of the coach was now in near darkness except for the occasional overhead light when Sonia did something unexpected, even now I'm not sure whether she did it on purpose or it was just a careless gesture but she put her hand on the seat next to her stared into the eyes of our watcher and then removed her hand again, this was a sign right or wrong and our man moved from his seat and sat down next to Sonia. Now fantasies are one thing but this could become something we had never done before and I for one was nervous as fuck, I grabbed Sonia's hand and gave it a squeeze as our new friend placed his hand on Sonia's thigh and gave it the slightest of strokes causing Sonia to squeeze back on my hand. Just as he was about to introduce himself Sonia placed a finger on his lips and said " we don't need your name or you ours" and then slowly traced his lips with her finger. Her hand now left mine and once again started to stroke my cock which was still painfully erect, her other hand then went down to his lap and began to playfully stroke the length of his cock through his trousers, looking down I saw him slowly moving his fingers up the inside of her thigh until they were now at her pussy pulling the material to one side again he felt her wetness and then brought his fingers to her mouth as she began to lick her own juice from him. This was like watching porn, my own wife in the lead role. By now her hand had freed our companions cock and was wanking it slowly as she did the same with mine my hand now at her pussy again gently playing with her clit as he placed his hand over mine and began to move my fingers towards her hole. This was unexpected having another man hold and direct me as I wanked my wife, but I was too far gone in lust to let it bother me, my fingers now inside her were then joined by his as we spread the wetness of her pussy down towards her arse feeling the puckered hole and ever so gently rubbing it in to her. Sonia once again had a little orgasm as our fingers slowly battled it out between her arse and pussy, as I turned to look at her she began kissing me again her tongue fluttering around the inside of my mouth, she then broke the kiss and turned to our friend, surely not I thought for some weird reason, she won't kiss him I mean it's ok to have his fingers inside her but a kiss,no. Then she kissed him and I was so turned on watching them I thought I would cum, never ever had I thought of her kissing anyone but me before, even in fantasies it hadn't happened, yet there she was and fuck was she enjoying it. She kissed our stranger for a good few minutes as the pair of us made her pussy and arse wetter and wetter, then slowly moving position on the seats she bent towards his cock and taking it in her mouth began to give a blow job worthy of an award. Her arse was facing me now as she maneuvered onto her side slightly sucking and licking the strangers cock as quietly as she could, her skirt up over her hips now I pulled on her pants and rolled them down her legs, my cock needed no help and was inside her without any hesitation her pussy so wet and warm all I could do was keep still as she moved gently backwards onto it then forwards as she sucked his cock. I put my hand round her chest and began to pinch her nipples gently when the man's hand came across and held mine pulling it towards my wife's face, what the fuck was he doing? He placed it on her face and I could feel his cock as it pushed against the inside of her mouth, next he moved her head back slightly causing his cock to come out of her mouth and then proceeded to wrap my fingers around it, he then gently pushed Sonia back onto it, so now he was moving his cock in my hand and Sonia's mouth as I was slowly fucking her, after that it felt like nothing was taboo and it turned out to be not too far from the truth. His hand came across and he put his finger in my mouth, involuntarily I began to suck first one then two, at which point Sonia stopped sucking him and turned around giving herself to his cock, she looked at me with his fingers in my mouth as I sucked on them like she had just been doing with his cock and came again just as his dick found its target. Only its target wasn't her pussy, he'd pushed against her arse hole not forced it in just gently against it and it sent her over the edge, her legs began to shake and her eyes glazed over, I don't think I'd seen her orgasm like that before. Now he was inside her pussy fucking her slowly as she built up towards another orgasm her hands on my balls her fingers tracing my arse hole gently prodding and then playing with the tip of my cock spreading the precum on her lips and licking it off, our mystery man with one hand squeezing her tits and the other with two fingers in my mouth, Sonia started to kiss me as I sucked and then started sucking his fingers with me looking me in the eyes the entire time. I knew I wouldn't be able to stop from coming soon as my orgasm began to build, then without warning the man pulled out of Sonia and holding us both lightly by the back of the neck brought us both down towards his cock, Sonia opened her mouth ready knowing what was about to happen, I was that close I could smell the pussy juice on his cock and without thinking licked the head of this total strangers cock and then it happened, his cock erupted cum all over Sonia's face and mouth and some getting me, I have never felt so much lust in my life and began kissing Sonia and licking her face, the taste of this man's cum off my wife's face was like nothing else I've experienced before or since. Sonia was bringing herself off as this was happening her fingers deep in her pussy you could hear the wetness as she fucked herself, then suddenly the man grabbed my cock and pushed it into her keeping us all locked together in a huddle as I furiously fucked her my cock buzzing with each thrust until finally I shot the most incredible load so deep into her pussy, legs trembling we stayed still not moving the three of us for what felt like forever until my cock slid out of Sonia's pussy. We sat up made ourselves presentable not speaking a word to one another, Sonia went to put her knickers back on and our friend took them off her and put them in his pocket gave her a kiss on the cheek stood up and walked down the bus before sitting in an empty seat. Within ten minutes we were both asleep and woke up just as the coach pulled into Liverpool bus station, home.
