Back in the days when most unconventional sexual activity was conducted via contact magazines, I hooked up with a guy named Dave. He was a rep., for some office equipment firm in Brum and seemed to have lots of opportunity to be out a lot. I guessed he was married but he never said. About the same age as me,( I was just 31) he had a bit of a cheeky disposition, describing himself as ' a Marty Feldman lookalike'. My husband and I had invited him to join us for a night of fun, finding his response to our ad in Rendezvous magazine amusing, which was not the usual approach. At the appointed date, however my husband was obliged to go abroad to work. I was supposed to cancel the meeting, but when I phoned to let Dave down, we got into a conversation and I just thought he'll be OK and decided to invite him to our home. This was a bit of a risk, and not something I'd done before on my own. Thankfully my instincts proved sound. he arrived about 9,00pm., when I'd had the chance to put the kids to bed and get my glad rags on. We really hit it off! and he did really resemble Marty Feldman. While we were laying on the rug, recovering from an energetic couple of hours full on fucking, he began to ask me about my fantasies. I said I didn't think I had any but he then shifted to films and I confessed to being turned on by Emmanuelle and her sexual awakening under the tutelage of the Svengali figure Mario. Over another couple of drinks, interspersed with more fucking and sucking, I agreed it could be exciting to let someone arrange and set up some sexual encounters which were outside my comfort zone. After he'd gone, I laughed at myself and dismissed the chat as nothing more than the product of the sexually charged evening and forgot it. Some weeks later, after a threesome with him and my husband, we sat around chatting and he reminded me of our earlier conversation. I tried to dismiss it but he persisted and then suggested I was not brave enough to put myself in unscripted situations. After all, he said, pre-arranged 'wife swapping' as he sneeringly called it, is not really challenging the accepted sexual protocols. This really annoyed me as I liked to think of myself as 'experimental' and open to new situations. So I replied a little tartly, that as long as my husband was OK with it, I would let him(Dave) organise an adventure for me and assured him, I was not as fainthearted as he thought. Suffice to say, he was quite keen and within a week I found myself being driven into Birmingham on a warm spring evening. Dave had arrived early to pick me up and supervise my outfit while my husband occupied the children. He gave me no clues as to what he had in mind and my mind was already awash with the possibilities. To my surprise, he had eschewed the tartier options that I had thought the obvious choice for such an adventure and selected a silky Champaign coloured wrap over dress that reached the knee. Admittedly it was almost transparent in good light and the outline of ivory underwear, bra thong and suspenders(husband's present from Paris) were visible to a studious look, Off white stockings and cream 4 inch heels completed my ensemble. As we drove along the Hagley road, somewhere just past the lights at Harbourne, Dave stopped the car. Gesturing to opposite side of the road he pointed out a bus shelter in which there were three or four young men standing. 'I want you to go and flash them guys' I began to protest, at which he said 'If you can't do that! we might as well go home. I will watch from here.' I got out of the car and walked the thirty yards to a pelican crossing and pressed the button.The sun was still warm and I was aware that its light exposed my figure perfectly to the drivers of the waiting cars. Feeling a flush of embarrassment,I kept my eyes ahead, crossed the road and turned back towards the bus stop. Glancing to the side I saw Dave smirking.' You bastard' I thought both annoyed and amused. Reaching the shelter I saw the guys were only youths, maybe seventeen or so. Engrossed in banter they ignored my arrival. To get their attention I enquired as to the time of the next bus. It was clear that the flimsy nature of my dress was not lost on them and while they affected to look away I knew my size ten outline was firmly on their radar. With a sharp intake of breath. I slipped the sash holding the wrap-over together and allowed it to fall open, then turning sideways onto the lads raised my left leg to the little wall at the back of the shelter. Undoing the suspender I adjusted the stocking rolling it down then back and re-clipping it. I repeated the routine with the right leg so they had a clear view right to my crotch. Then holding the dress wide apart I did a little shimmy closed it and fastened the sash.They starred open mouthed. Wishing them a great evening I turned and headed back to the car wondering if I had managed to do enough to get Dave's approval. A couple of car horns honked as I crossed the road.' At least someone appreciates the display' I thought realizing I was trembling and feeling giggly. I got in the car 'Did I do ok?' he Just took my hand and placed it on his cock. Even through his trousers he felt hard. We both started laughing.' fucking great' he said 'How do you feel?' 'Good' I replied. Still surprised and exhilarated by my boldness, I suddenly realised the car had turned off the main road and Dave was parking up outside a casino. He passed me the raincoat he'd suggested I bring in case of the evening turning cool. 'Slip this over your shoulders' he said as I got out. Their was a uniformed flunky on the door. I'd never been in such a place. We checked the raincoat in at the cloakroom. Dave was clearly a regular there and on familiar terms with the old guy on the desk. Throughout their brief exchange I was aware he was checking me out in a fairly obvious way, his eyes scanning the dress and pausing where he discerned the outlines of my underwear. Guided by Dave into the bar of the casino I settled in a leather chair while he collected some drinks.' old Fred liked your dress ' he joked. 'I think he was more interested in what I've underneath' I responded. 'he won't be alone in that, I'm sure.' ventured Dave. We ordered another round of drinks and Dave showed me how to play roulette. He was right about interest in my outfit, every time I looked up I would catch some guy blatantly scrutinising every inch of me. A bit unnerving but also ego boosting. I was under instructions from my mentor not to adjust my dress in any way and allow it to do its worst. If that exposed my stocking tops or give an over generous glimpse of a breast then fine. After being a few pounds up, I managed to blow all our winnings and the initial stake in one game. Dave indicated it was time to go. I was a bit surprised having expected something of a sexual nature to happen when we were there. We collected my raincoat and were about leave the cloakroom when old Fred muttered something to Dave. Dave returned to the desk. 'That is a disgraceful suggestion Fred my friend, This is not the sort of woman who goes out without her knickers!' His voice was stern, and Fred looked a bit uncomfortable. 'If you allow her behind the counter, I'm sure she will show you how wrong you are'. Now it was my turn to be ill at ease. Fred lifted up the counter and Dave ushered me through into the room where the coats were kept. He instructed me to bend over and touch my toes. Giving him a furious look I complied. 'Ok! Fred you can lift up her dress and see for yourself'. I felt the hem of the dress being raised then dropping over my head. I imagined what Fred could see. My behind,its twin cheeks separated by the thin string of my thong, the suspenders taught over naked buttocks.The tight triangle of silky fabric just containing my neatly trimmed cunt. 'As you see Fred, she is decently clothed, and in good quality attire. I'm sure you would like to check the fineness of the fabric yourself, feel free.' Fingers slipped under the string and traced it down the valley of my arse to where it met the apex right over my butt hole. 'Spread your legs so Fred can fully appreciate the total modesty afforded by your garment' I shifted my legs apart and Fred's fingers slid under my fanny. My legs trembled. Dave continued his commentary. 'Just check how neat and tidy she is down there Fred, and is her opening readily accessible?' A couple of fingers parted my labia and probed my fanny. Another hand pushed the flimsy scrap of the thong aside and penetrated my cunt from the front. ' I can see its a two handed job' Dave ventured. The attention was beginning to get a reaction from my nether regions and involuntarily I found myself gyrating against the old mans fingers and knew my cunt was lubricating. By accident or design Fred was teasing my clit perfectly and I had to put a hand to the counter to steady myself. Not sure what was expected of me I tried to remain silent and wait instruction, managing to limit my acknowledgement of the assault on my fanny to muffled grunts. In my minds eye I pictured the scene. An old man fingering an anonymous cunt, watched by her partner or controller. I felt at the same time ashamed and eager for my debasement to continue, I wanted to be told to fuck the old man.He for his part was doing a great job. teasing my clit from the front and finger fucking me from the rear, his mouth slobbering all over my arse. Dave's voice interrupted my slide into orgasm ' Well Fred, you can see that everything is in order and that this lady is not one who goes without underwear to tease old men, we have to go now. Please adjust her garments'. The fingers relinquished their attention to my fanny to my disappointment, rearranging my clothing as instructed, my dress pulled back over my behind. ' You can stand up now' Without further comment Dave took my arm and carrying the raincoat ushered me out to the car. 'You were annoyed with me for making you expose yourself to Fred weren't you but now you are angry I stopped him before you got fucked,. Right?' I had been stony faced since we got back in the car and looked out of the window as we moved towards the city. He was spot on. Initially I had been humiliated but actually got off on the situation and would have come heavily if not interrupted.'Do you want to carry on or go home' Dave demanded calmly. ' I think Fred was at least as disappointed as you!' This made me smile and I responded ' What are we doing next?' The light was dropping now and we were heading out along the Bristol Road. 'I thought we'd take in a movie' Dave gestured at an old cinema on the left as we past. It was clearly a place of former glory now showing 'adult' films. In our discussions he had described such places and I knew that they would be patronised by guys who went to jerk off to the film.he parked up and leaving the raincoat in the car, walked a couple of hundred yards to the cinema. Dave was a member (course he was). He paid and guided me through the doors. It was as I expected, dimly lit by the flickering light from the screen. Most of the seats seemed empty but as my eyes adjusted I could make out a figure here and there. We stood at the top of the aisle. 'Give me your dress whispered' Dave.I hesitated but he held out a hand and I undid the sash belt, slipped off the dress and handed it to him. 'Pick a seat seat' instructed my mentor. looking straight ahead at the screen but not really seeing it, I made my way forwards. About midway down I picked a row where no one was sitting, stepped in a couple of seats and sat down. Dave sat next to me putting the dress over the seat in front. More comfortable now seated, I took in the events on the screen. A big breasted woman was deep throating (something I could never do),a black guy while being furiously fucked from behind by another. Scanning the audience trying not make eye contact, I wondered if my entrance had registered with anyone. No one seemed to show any interest. As if reading my thoughts, my mentor suggested I should get up and walk to the front of the rows, parade before the screen and then come back. I complied,attempting what I thought was a catwalk style gait, with a couple of turns while at the front. There were more people in the place than I'd first thought but no other women as far as I could tell. When I got back to my seat Dave pulled my hand to his groin. He had his cock out and I began to slowly jerk him off. Returning the favour his fingers pushed aside my thong to gently probe my fanny. On the screen the same woman was now being fucked up the arse. Aware of movement to my left and a strong whiff of Paco Rabanne I saw a man had moved into the next but one seat to me. Pretending to ignore him I continued pulling on Dave's meat. The man moved next to me. After what seemed an age, a hand explored my left breast over the bra, then meeting no resistance pushed the cup up and over my tit to tweak the nipple and squeeze the flesh properly. He repeated the action with the right breast and then I felt his mouth on my left nipple, tonguing and sucking like a suckling pig. I had maintained my front looking pose as though whatever was happening was to someone else but my new companion now fastened his lips over mine and was forcing his tongue into my mouth. I hadn't anticipated any snogging being involved and had thought it would turn me off but in fact it was the opposite and I felt myself responding to this anonymous bloke. Happily he didn't have bad breath which always kills the mood. So we engaged in a bit of tonsil tennis and continued getting acquainted. My new partners hand slid up my leg, and I felt Dave's hand retreating to give the newcomer uncluttered access to my cunt. His fingers felt strong and stubby, pushed under my fanny lifting me out of the seat to push at my arse, then slipped back to probe and rub my insides, picking up quite nicely from their predecessors efforts to get me writhing gently. Almost embracing me and more in my seat than his own, his mouth worked its way down slobbering over my breasts and down past my navel.As he lifted my leg over his shoulder I was aware of hot flesh pressing against my cheek. I had it seems, not been giving Dave's dick sufficient attention and I turned my mouth to it and sucked it in. My new partner was working my fanny with his tongue and I tried with to give the cock the same treatment. Suddenly Dave's voice broke into my reverie.' Strange cock in your mouth and some strange tongue in your cunt, you are pushing the envelope'.He was clearly in the row behind me, so the throbbing meat I was slurping on so avidly belonged to some other anonymous guy. As I tried to process this realization, the anonymous cock pulled free of my lips and I watched in close up as a hand fisted it to a conclusion, spattering my face and hair with warm fluid. Its owner muttered something undecipherable and shuffled off to be immediately replaced by another pair of trousers already opened and framing an erect penis and hairy set of balls.I took the uncircumcised tool in my hand massaged its length and fondled its sack. An average bit of tackle I thought, what a connoisseur I am becoming. Guiding it to my lips I began to tongue it, a bit distractedly. The guy downstairs was really hitting the mark and that combined with the sordidness of it all brought me to a groaning orgasm! There was a bit of a pause while all involved took stock, Then the downstairs guy seemed to be of the opinion that he needed some quid pro quo for his efforts and began maneuvering me into the kneeling position on the seat. Dave and the chap I was blowing continued to fondle my breasts throughout as I slipped a hand back through my legs to guide the again moderately dimensioned knob into my fanny. In a few energetic thrusts both men were done one holding my head tight to spew its sticky load in my mouth the other gripping my hips and slapping my arse till he shuddered his load inside me. I was vaguely aware of other guys waiting their chance but Dave's voice came over, calm but firm ' Ok Guy's, the shows over for tonight '. He gathered me up and escorted me away. Helping me into my dress and slipping the raincoat over my shoulders he steered me to the car. He never stopped telling me what a fantastic woman I was all the way home. The divulging of the nights adventures to my husband, resulted in the three of us cavorting on the carpet till the early hours of the morning. There were several more visits to the Bristol Road cinema that summer.
