This is another account of an adventurous day that Lou and I had back in the early naughties. You may have read about our encounter in Oxford or our session at Chameleons. Lou and I have a long distance relationship that we spiced up with meetings around her home town of Nottingham, my home town of Portsmouth or, to be less inhibited, anywhere else in the UK! Lou is a slim and sexy 34B bottle blond, 5 foot 5 tall with a mouth made for sucking cock and she loves to swallow cum - heaven! On this occasion we planned to go on a shopping trip to Meadowhall near Sheffield, with some fun and games on the way and whilst we were there. Lou loves to spice things up so we agreed that she was to wear a knee length denim dress that has popper buttons all down the front. This was complimented by ankle boots, stockings, suspenders, quarter cup bra and nothing else. We planned to travel by a slow 'milk run' train that called at the likes of Ilkeston, Chesterfield, Dronfield and others - we wanted as many stops as possible for what we had planned. Lou and I boarded the train separately. I took a right hand aisle seat facing the direction of travel near the rear of the carriage. Lou came on a few minutes after me and sat in the aisle seat opposite and facing me with her back to the direction of travel. To anyone looking on we were not together - we wanted her to appear alone without anyone who could correct any of the dressing slips we were to arrange. Lou set herself up reading a magazine held at her midriff and surreptitiously popped buttons of her dress near her upper thigh such that when she crossed her legs her dress gaped open and even from where I sat I could clearly see her stocking tops, bare thigh and a hint of pussy. This display was just as we practiced and we settled back to allow Lou to 'show', apparently unintentionally, whilst I observed anyone who got lucky enough to catch sight of her charms. There were a few men (and women) that did noticeable double takes as they passed down the carriage. A number also seemed to be passing back and forth to the end of the carriage more times that necessary no doubt getting repeat eyefuls of what Lou had on display (thinking that she was unaware of her wardrobe malfunction). A lady getting off at the first stop actually paused alongside Lou to discretely advise her of the open buttons and that she may wish to adjust her dress. Lou feigned surprise, thanked her, and made to fix the gap. Once she had got off the train though Lou reopened her buttons to put her show back on and recrossed her legs - we both smiled knowingly at each other. When a particularly good looking guy or attractive lady was about to pass I gave her a subtle nod and she eased her knee wider to spread her thighs to make her shaven pussy even more prominent. I could tell by the way Lou was squirming on her seat that she was enjoying the exhibition she was putting on. I was on hand for her assurance but, to all others, she was travelling alone. A further element of her train display was to discretely undo some of the poppers at the top of her dress. She arranged herself such that should anyone be standing alongside her waiting to leave the train, and had the good fortune to look down at her, they would have an uninterrupted view of her right breast and nipple. This was the purpose of the quarter cup bra - to tease her nipple with the material of her dress when walking but, more importantly for us, it could provide a fantastic bare breast downblouse view to departing passengers. From my vantage point across the aisle I couldn't see what the 7 or 8 men saw as they looked longingly down at Lou - although from what we practised I do know that they were looking at a bare breast and pert nipple (that we circled with red lipstick before setting out for viewing prominence) and none of them told her that she was displaying more than she might like! There was one man in particular getting off the train at Dronfield that I thought was going to miss his stop as he was so captivated at what he could see - the passenger behind him had to give him 3 or 4 prompts to move along. When we arrived in Sheffield for our change of trains Lou made herself decent and we got off the train separately. I followed her from a distance, allowing Lou the freedom to flash me or anyone else she fancied. Lou squated down to look at a magazine on a newsstand in the station and, whilst she was facing me, she parted her knees showing me her stocking clad legs and shaven pussy with engorged lips. I was about 10 metres away and looked around and noticed the male of a couple also looking at Lou. He was trying not to be obvious in doing so lest he be caught by his partner. Lou was apparently oblivious of her unladylike positioning but she and I knew better and her charms were alluring. After a minute or so of this she stood and returned the magazine, walked towards us blanking me (as agreed) and smiled at the lucky man next to me and making her way to the Meadowhall train. I followed along and the next part of the journey was short and uneventful and we arrived at the retail park and set out to find a clothing store with changing rooms that fit our needs for the next act. I think it was Top Shop near Denenhams where Lou entered the store ahead of me. She selected a few blouses and a skirt to ostensibly try these on and made her way to the changing rooms at the back of the store. She entered a cubicle that was close to the entrance to the changing rooms and shed all her clothes, including her stockings and suspenders, but left her ankle boots on. Lou had brought along her own sheer top with minimal lace embroidery that is long enough to be classed as a mini dress as it goes down to her mid thigh. She usually wears this with a camisole underneath it but not today! She took the sheer top from her bag and put it on and, as planned, adjusted her dress to ensure that her nipples were positioned behind sheer material, and not any lace; Lou then drew the curtain aside and stepped out of the booth. I was positioned near the entrance to the changing rooms, joining the 2 or 3 other men who were waiting for their partners to try stuff on. I could clearly see her slowly and deliberately exiting the booth, stunning in her near nakedness masked by an almost transparent mini dress that had tasteful lacework that left nothing beneath to the imagination. To everyone else who saw her, and at least 2 other guys did given their expressions and change of demeanour, she was trying on something she had picked off a rack in the store - only Lou and I knew better. Lou slowly made her way to the end of the corridor and out of our sight to check herself out in the mirror at the end of the hallway. We had agreed that she was to remain in the changing room corridor, turning this way and that, including with her her back to the mirror to allow her to look over her shoulder at her reflection (and therefore displaying her tits and shaven pussy back down the corridor), until at least 2 other women had seen her (Lou is bi and not curious so this was very much a thrill for her). This took a couple of minutes and Lou told me afterwards that she could feel juices running down her thighs as she was so turned waiting to be seen with so much flagrantly on display in a public place. When she had met her target of being seen (neither woman approached Lou but they saw her barely concealed nude body) she made her way back to her cubicle where she briefly came back into the view of those of us near the entrance. We caught site of her full frontal appearance, beautifully encased in sheer material, and her nipples were noticeably engorged and prominent. Lou slowly stepped into the booth and got changed back into her dress, put her sheer top back into her bag and, with a smile, left the clothes that she never did try on with the store attendant. We had to deal with the pent up passion we had created on the train and in the store. We made our way to one of the multi story car parks, the pink one, and came upon a stairwell at the far end. There were no subtleties, Lou sank to her knees and took my hard throbbing cock into her mouth. Holding her head and controlling the pace of her deep throat actions I told her how much her pussy being on display on the train, and the downblouse views she had given to passengers, had turned me on. I also told her that from what I could see she had put on a perfect display in the changing room and at least 2 other men had seen her in her sheer outfit. I couodn't last much longer and I had to take her and lifted Lou up before she tipped me over the edge, turned her around, lifted her dress and bent her over. She was so wet that once I placed my cock against the entrance to her pussy she pushed back against me and I sank in balls deep in one stroke. With the (exciting) risk of being caught in the back of our minds we made love with passion; I angled my cock to maximise the stimulation of Lou's clit and Lou helped things along by teasing her nipples, pussy and occasionally placing fingers on either side of my cock squeezing my shift as I stroked into her. I held off until Lou came (noisily as always) and, to avoid a pussy leaking cum for the rest of the day, once she had come down from her orgasmic high she span round to finish me off into her mouth. She lapped up her juices from my cock and, using her tongue and well practiced suction techniques, soon coaxed out 5 or 6 ropes of heavy cum right to the back of her throat. Lou loves sucking cock and didn't flinch, swallowing the lot and she didn't let up until my softening cock was thoroughly cleaned; a great session! The rest of the day was spent in the afterglow of great sex with a repeat train display on the way back to Nottingham (which had more passengers satisfied by being fortunate enough to catch sight of Lou's wares). A memorable day out that we both look back on fondly.
