We live in a three storey house, with similar houses opposite. As on many modern estates, the houses are close. The house opposite only about 50 feet away, the width of the road, pavement and a small strip of garden in front of each house. The windows are virtually opposite each other and you can see into the lounge and main bedroom of the other house when the lights are on and curtains open. For some reason the builder included double patio type doors, leading from the main bedroom onto a balcony which has no practical purpose and is to small to sit out on. We've lived there for about 3 years, Jennifer and Paul bought the house opposite late last year. They are an attractive couple a little older than us. Paul is about forty, tall, slim and nice looking. Jennifer is 36 years old, about 5' 5” tall, short blond hair, slim, with fantastic legs which she shows off wearing short skirts and dresses. She has large tits, which Adam, my other half, couldn't keep his eyes off, wore low cut jumpers and tops, showing a lot of cleavage or sheer semi see through tops, frequently and very obviously without a bra. They invited us and several neighbours to a house-warming party soon after they moved in. We got on well and invited them over for dinner a couple of weeks later. We went out for meals, or to the pub with them. The conversations were sometimes quite flirty and suggestive and though they weren't explicit and without them specifically suggesting anything we suspected they were Swingers and got the impression we were being sounded out. The impression was reinforced when Adam told me after the third or fourth time we'd been out with them, that Jennifer had not been wearing panties and had been flashing her pussy at him when I was talking to Paul. The first time it happened he'd assumed it was accidental, but when she did it again he realised that Paul had been deliberately distracting me. We weren't sure if she was just teasing, hinting at more or if it was a game they played for kicks. We talked about what we would do or say if they suggested anything but didn't really come to any firm decision, though it's safe to say that Adam was probably keener than me at that stage. The next time we went out, I made a point of watching her in action. We had our drinks and were waiting for a table to become available to eat in the pub restaurant. I noticed her cross and uncross her legs very deliberately, but couldn't see if she was wearing panties. I said I was going to the loo, but instead hurried outside to the pub patio. It was dark outside, I couldn't be seen but I could see in. She can hardly have waited for me to leave the bar before she started flashing. Sitting on a high backed bench, her back to the room, she'd already swivelled towards Adam. Angled half way towards the patio doors, she was sitting opening and closing her legs, exposing her cunt to him, both her and Paul chatting as if they were unaware, while Adam struggled not to stare at her exposed pussy. I watched for a minute or two, wondering how she had the nerve to do it. I was turned on watching her, imagining how it must feel to blatantly expose one's pussy to guys. The thought excited me, I touched myself through my clothes, felt my sex moisten, a trickle of juice wetting my thighs. I watched for a few moments longer then quickly nipped into the loo. I locked the cubicle, pulled my String down and touched my pussy. I ran a couple of fingers along my gash and dipped them into my pussy. I was incredibly wet after witnessing her performance. If I hadn't already been gone for several minutes I would have sat in the cubicle masturbating. Reluctantly and feeling randy as hell, I wiped my pussy, tidied myself and went back to join them. They were all sitting as if nothing had happened when I rejoined them and I didn't get an opportunity to tell Adam I'd been watching. By then we'd known them for a few months, it had been a pleasant evening, a nice meal, good conversation. Drinks at the bar afterwards, Jennifer perched on a stool, her short skirt riding up showing a lot of leg, and more than the hint of stocking top. She was getting plenty of looks from guys and, though I couldn't be certain, I suspected she was flashing her pussy at them. They invited us back to their house for more drinks. As the booze flowed, Paul made some comment about Jennifer's tits and how much they'd cost. She responded by asking if we wanted to see them, pulling her top up without waiting for an answer, boasting that she'd had them augmented to a size 34ff, inviting us to have a feel. Adam didn't need asking twice and had a good grope, cupping her breasts and stroking her hard nipples while Paul looked on, unconcerned. She took her top off completely, unselfconsciously tweaking her nipples, inviting me to touch her tits. Out of curiosity I had a feel, surprised that they felt and looked quite natural. Grinning at me she gave one of my tits a squeeze through my clothes and dared me to remove my top too. I moved her hand away and said I didn't think I could, looking at Adam for support. “Go on. You've got lovely tits. Jennifer's got hers out” he replied unhelpfully, starting to unbutton my blouse. I made a half-hearted attempt to stop him, then gave in with a giggle. Both excited and nervous, I let him undo the buttons and pull my blouse open revealing my lacy, black half cup bra. I leant forward allowing him to tug the blouse from my skirt and pull it down my arms, momentarily trapping my arms behind my back. Jennifer, took the opportunity to unfasten my bra. As soon as my blouse was free of my arms, Adam dropped it on the floor and my bra swiftly followed. I'd had quite a lot to drink, felt relaxed, and quite uninhibited, displaying my tits to them, conscious that my nipples had stiffened, signalling my arousal. My tits are only 32b, and looked smaller sitting next to Jennifer. Without asking she reached out and caressed my tits, complementing me on how pert and firm they were, brushing my already erect nipples with her fingers. My nipples are very sensitive and when she began to roll them between her finger and thumb, I sighed with pleasure, resting my head back against the back of the settee. Her soft fingers, gentle touch, was soothing and exciting. I knew I should have stopped her, when she bent over, her hair touching my tits as she moved a hand away. She stuck her tongue out, licked around both nipples, flicking them with the tip of her tongue. I felt her taking my hard nipple between her lips, sucking it into her mouth, teasing it with her tongue. I gasped, then moaned, becoming more aroused, responding to her by pressing my breast against her mouth, sighing how nice it felt. She moved her hand from my other breast, lifting herself to lean over to suck the nipple. At the same time I felt her wriggle, opened my eyes watching as Paul unzipped her skirt, eased it down over her hips, pulling it down her legs and off, leaving her naked except for a pair of hold up stockings. I glanced over at Adam, he smiled at me encouragingly, moved closer, whispering in my ear to raise my bum to allow him to undo my skirt. Jennifer already had a hand on my thigh and had pushed my skirt up. I hadn't been aware until that moment that I'd had my legs parted, the tiny lace see through String, pulled tight into my slit, my labia splayed either side. Rather than embarrassment I felt a sexual thrill, realising that for several minutes I had been displaying my pussy to Paul. She stopped sucking my nipple, and huskily urged me to let Adam undress me, at the same time moving her hand higher, her fingers touching my pussy. I felt her easing the string from my slit, pulling it to one side. There was no hiding my state of sexual arousal, my pussy wet and gaping even before she slid two fingers into my love hole. She huskily asked me again to let Adam strip me naked like her. She pushed both fingers into my cunt as far as they'd go, her thumb rubbing my swollen clitoris. She began to finger fuck me, her mouth finding my nipple again, sucking and gently tugging it with her teeth. I lifted my bum, urgently asking Adam what he was waiting for and to get me naked. My skirt and string quickly joined my other clothes on the floor and I laid back, spreading my legs, wantonly displaying my smoothly shaven cunt to them all. Jennifer, sat back next to me, spread her legs too. Taking my hand she placed it on her mound. I could feel a small strip of trimmed, soft pubic hair above her clit. She had her hand on top of mine and pushed my hand between her legs and pressed my fingers into her very wet pussy. She moved her hand from on top of mine when she was sure I'd relaxed and was fingering her without her help and put her hand back on my pussy. We sat with our legs wide open, fingering each other. I felt a surge of excitement, performing a sexual act in front of the guys, which only increased when Jennifer, kissed, licked and sucked her way down my body to my pussy. I'd be lying if I said it was the first time I'd been touched by or touched another woman. I had a relationship with another girl at Uni. I had sex with her, including Oral, using dildos and vibrators to pleasure one another and on occasions fucking each other with strap ons. It wasn't something I'd ever told Adam about, which probably explains the surprised look on his face when I eagerly fingered Jennifer, and willingly, allowed her to go down on me. The pleasures of those previous times came flooding back as her tongue flicked against my clit and wormed its way into my sodden cunt. She broke off performing cunnilingus on me, quickly telling Adam and Paul to get undressed, before I put my hand on her head and pushed her back down between my legs. I could feel the first tingles of a building orgasm, but was slightly distracted watching as Paul undressed with his back to me, listening as he asked Adam if he wanted to fuck Jennifer. The inference wasn't lost on me. He obviously expected to fuck me. I was about to say something, when Paul stepped out of his underwear and turned around. He had what was easily the largest cock I'd ever seen, except for in a porn video. Easily 9 inches, possibly a bit longer, thick and heavily veined forming ridges along the shaft. He stood stroking it. I didn't wait for Adam to reply, without hesitation telling him he could fuck Jennifer. I greedily turned my attention back to Pauls magnificent cock, watching him wank his prick. It seemed to get even larger as he became fully erect, the foreskin pulled back, a large bulbous knob, clear juices seeping from the tip. Nothing would have stopped me from letting him fuck me. I could hardly wait to feel it inside me I felt my pussy flutter, as Jennifer sucked and nibbled my clitoris. I sighed with the pleasurable sensations spreading out from my cunt but I wanted to get my hands on Pauls beautiful prick. I turned my head looking at him. I'm sure he could detect the look of lust in my eyes as I put my hand out, asking him to move closer and let me touch his cock. He moved to the side of the settee, holding his cock, offering it to me. I took hold of it, unable to suppress a moan of desire as I wrapped my fingers around his thick pulsing shaft and slowly stroked his prick, feeling the ripples and bumps, his cock pulsing as his blood pumped through the engorged veins. He put one knee on the arm of the settee, rested a hand on my head. He pushed his cock towards my mouth, pulled my head closer and told me to suck his cock. Unhesitatingly I opened my mouth, licked the pre cum seeping from his knob, tasting the saltiness, before parting my lips, slowly taking his cock into my mouth and sucking his cock. From the corner of my eye I saw Adam getting behind Jennifer, putting his hands on her waist, lifting her, parting her legs. I knew he'd entered her and was fucking her when her mouth pressed more firmly against my cunt. She began sucking the juices from my pussy as he fucked her. My arousal increased rapidly, Jennifer's tongue erratically lapping my pussy, I was intensely aware that my husband was fucking her, whilst I had her husbands cock in my mouth. I avidly sucked Paul's cock until I was forced to stop when I climaxed. Her mission accomplished she told Adam to pull out while she moved and bent over the arm of the the settee. I heard her ask him if he was into Anal sex, telling him he could fuck her up the arse if he wanted too. Adam seemed to pause and think about it but said he wanted to fuck her pussy this time, re-entered and resumed fucking her. She said she wanted him to fuck her harder, and faster. At about the same time Paul pulled his cock from between my lips. He laid me on the settee, lifted one of my legs over the back, got between my legs, spreading me wide. He slid his knob back and fore along my gash, rubbing my clit, spreading my sex lubrication over his prick. Jennifer's head was above mine, she smiled down at me, our eyes locked. She whispered, “Enjoy” as I felt Pauls rock hard cock part my pussy lips, opening my wet, cock hungry, cunt. As he entered me she bent forward and kissed me passionately on the lips, my mouth opened for her tongue. I gave a gurgling groan as I felt Pauls cock entering me, stretching my hole to accept his thick shaft. He slide more up me slowly, it felt incredible, inch after seemingly endless inch, invading my tight fuck hole. Finally he fully penetrated my cunt, his balls touching my bum. Jennifer, raised her head, winked at me as Paul began to thrust his fat cock in and out of my appreciative pussy. Above my head I could see Jennifer's big tits jiggling as Adam thrust into her. Heard her gasp and moan, supporting herself on one hand, using the other to tease and pull her large hard nipples. I began pushing back, wanting Paul deep inside me, moaning, sighing, then finally breathlessly begging him to give it to me hard and to cum inside me. I was so engrossed in my own lust and pleasure I was barely aware that Jennifer and Adam had both cum and were kneeling, watching Pauls rampant cock, slamming in and out of my cunt. All I was aware of were the wonderful sensations spreading out in waves from my pussy and the throbbing, pulsing, rampant cock, filling my cunt. My cunt spasmed, gripping his cock as I had an incredible orgasm, he continued fucking me, squeezing my tits, pinching my erect nipples. My first orgasm started to subside, but a second was already building. “Fuck me harder. FUCK ME, FUCK ME HARD. CUM IN MY CUNT” I screamed. He rammed his cock deep inside me, slamming his lovely cock rapidly in and out my highly aroused cunt. “YOUR COCK'S INCREDIBLE. I'M CUMMING. GIVE ME YOUR SPUNK. CUM INSIDE ME. FILL MY CUNT WITH SPUNK YOU DIRTY FUCKER” I loudly demanded. I felt his cock pulsing in my pussy. I climaxed, as he ejaculated, three or four times, pumping his spunk into my willing and receptive cunt. I felt his cock twitching inside me, forcing the last drops of spunk from his prick into my pussy. I laid back, still impaled on his cock, smiling dreamily at Adam. I felt Paul beginning to withdraw, lifting my leg off the back of the settee, putting both my feet on the floor. His cock still just inside me, Jennifer placed her hand on my pussy and slid it over my hole as he pulled out, trapping his spunk inside me. She turned to Adam and asked if he wanted to clean me and lick Paul's spunk from my pussy. He looked a bit uncertain, glanced at me. She shrugged, said she'd do it, then to my surprise he stopped her, said that he wanted to go down on me and taste my pussy saturated with another guys spunk. He started off tentatively, but then began licking and sucking my pussy with increasing enthusiasm, drawing every last drop of Pauls spunk out of my cunt, swallowing the cocktail of semen and my sex honey, licking his lips with relish, when he surfaced. I briefly wondered, given his apparent taste for spunk, if he might be tempted to suck another guys cock. The idea of watching him giving another man a blow job excited me, but I dismissed the thought as ridiculous. Afterwards we sat chatting, had another drink while they told us about some of the things they did. It seemed a foregone conclusion that I would go to bed and spend the night with Paul and that Jennifer and Adam would sleep with each other. Paul fucked me again before we slept. I was woken in the morning by the feel of Paul's hard cock pressing against me, him spreading my legs and fingering me. I pretended to be asleep until he rolled on top, guided his cock into my cunt and I wrapped my legs around. He fucked me to the sound of Jennifer and Adam energetically fucking in the other bedroom. I climaxed twice before he pumped his spunk into my pussy, cumming almost as heavily as the previous evening, flooding my cunt with his seed. With Adam otherwise engaged, and unavailable to clean my pussy, I showered, flushing Paul's spunk from my cunt, before drying and going downstairs naked to retrieve my clothes. Everyone else was already dressed. I didn't bother with my underwear just putting in my skirt and blouse. Jennifer grinned and suggested that next time we went out I should go without anything under my clothes and we could both flash our pussies. I didn't need to ask Adam, before agreeing, certain he would be keen for me to do it. They also had some other suggestions, including moving our bed, so it was opposite the balcony doors so that they could watch us fucking from their bedroom. We went along with that, once we checked that no one else could see from any of the other houses. They told us that they were having a few similarly minded people around the following weekend, but unfortunately weren't able to invite us. They had a rule that no one else joined their parties, before the other participants had met them socially and agreed and there was insufficient time to organise it. They did however say that if the others agreed, they'd leave their bedroom curtains open we could watch and perhaps put on a show of our own to allow the others to at least see us. I could see Adam was looking at me expectantly but reluctant to make a decision. I wanted to continue and explore my sexual boundaries and immediately said we'd do it, especially if it helped to get us invited to one of their parties. That night we went to bed, opened the curtains and turned on all the lights. Kneeling just inside the balcony doors I sucked Adam's cock then he fucked me while they lay on their bed masturbating while they watched. That was just the beginning. There were six couples at their party and four unattached guys. We watched from our bedroom as two couples fucked opposite. Jennifer sent me a text telling me to do a sexy strip in front of the window and to give Adam a blow job. I felt incredibly turned on knowing I was being watched by strangers. I put on as dirty a show as I could, caressing my naked body, stroking my tits, touching my pussy. Adam had to warn me several times that I was getting to close to the window and risked being unintentionally seen. It was a mild evening, I asked him to open the doors and fetch me a chair. I sat on the chair, legs spread wide, feet on the door frame and began to masturbate. I fingered my cunt, pushing three fingers in, then four, vigorously masturbating, stretching my hole. I folded my thumb into my palm and pushed my hand further into my pussy. I was so highly stimulated, my juices flowing, that my hand easily slid into my cunt. I bent my arm, pushed my hand in up to the wrist, closed my fingers around my thumb and began to fist myself. I began to frig my clitoris furiously. Imagining I was being fucked by Pauls big cock I came loudly. Forgetting that I was supposed to give him a blow job I pulled my fist from my cunt, grabbed Adam, dragged him to the bed, mounted him and rode him, facing the window, hoping they could all see his cock in my cunt. I came again before he gave me a nice load of spunk. Secretly I had hoped that my show might be enough to get us an invite. Sadly not. Instead I watched enviously and jealously as Jennifer was fucked by three guys. I suspected and she confirmed the next day, that she had taken a cock in all her holes and I had seen her being anally and vaginally DP'd. I asked what it felt like, she told me I'd have to wait and find out for myself if I wanted to know. It was another month until the next party, time to be introduced to, and accepted by the others and have some further adventures with them. Our horny neighbours had introduced us to a whole new outlook on sex. We were both eager to learn more, push our limits and experience uninhibited sex with them and others. That as they say is a story to be continued if you're interested.
