How can this have happened so easily, in just a few short months? I've always liked sex, I'd usually cum and thought what I was getting was satisfactory, though I didn't have much to compare it with. I'd been married to John for 20 years, one of only three men I'd ever had sex with until six months ago when I discovered that he had been having an affair. She was twenty years younger than me and had much bigger tits that's for certain. I'm forty nine years old, 5' 6” tall, I think I'm attractive and proud of my figure. I've always had good legs, my bum trim and still firm, my tits are small, a pert 32b and though I say it myself I still look good in a bikini. That's probably what hurt most. I'd worked hard to look good, hadn't let myself go, but he clearly found someone younger more attractive. Despite John promising me the affair was over, I moved out to stay with a friend while I decided what I wanted to do. It did little for my confidence, I think I was in shock at first, just wanting to hide and it took some persuading to get me to go out. Sharon is a bit younger than me, had been divorced for several years, taken her ex to the cleaners and had a lovely cottage set in a large secluded garden, just outside town. I knew she was quite promiscuous and had lots of male friends. At first I found it embarrassing, laid in bed, listening as Sharon noisily and enthusiastically fucked. I also found it surprisingly arousing. I'd not long gone through the menopause, and I'd expected my sex drive to wane, but the opposite seemed to have happened. Until I found out what John had been doing, I'd been hornier than I had for years. Once I realised there was no chance of her and her man hearing I began to masturbate while I imagined I was being fucked by some hunk. I'd left my sex toys at home, sex had been the last thing on my mind when I moved out, but listening to Sharon I needed some sexual outlet and bought a couple of vibrators. Using them to masturbate almost every night, increasingly frustrated and jealous of all the sex she was having. She tried to persuade me that if John could fuck some bimbo there was no reason why I shouldn't go out with other men and have sex. She reassured me that I was a very attractive woman, guys would definitely want to fuck me. “Young guys love fucking older women” she insisted. I was weakening, having sex with a younger man would certainly give my confidence a boost. I finally went out with her one Friday night, earlier this year, being introduced to guys she knew. I quite fancied a couple of them, and Ian the guy she was with that night, who I'd not met before, looked about 26 or 27 and was gorgeous. I lost my nerve, had a bit to much to drink, made an excuse and got a taxi back to her cottage. I regretted leaving as soon as I saw my empty bed. I undressed, had a shower, made a coffee. Sharon probably wouldn't be back for ages, then I'd have to lay awake listening to her shagging. Thinking of her being fucked by Ian I went up to my bedroom, took off my gown and lay on the bed naked. I touched my tits, teasing my nipples until they were hard. I opened my legs, running my fingers through the soft dark pubic hair. I touched my pussy, juices already seeping out. I touched my clitoris, rubbing the little bud, feeling it harden, masturbating whilst thinking about Sharon's man. I wanted more than my fingers. Taking my vibrator from the bedside cabinet I wet it with saliva and switched it on low speed. I held it against my clitoris, moving the tip in little circles, before slowly sliding it into my wet, slippery cunt. I turned it up to a faster speed, closed my eyes, enjoying the sensation of the silicon cock loudly buzzing in my pussy. I began vigorously fucking myself with it, moaning as my excitement intensified, fantasizing that it was Ian's cock pumping in and out of my pussy. With the vibrator humming at full speed, all the noise I was making, I hadn't heard them come home, or coming upstairs, or the bedroom door opening. I wasn't aware, but apparently I was calling out “Fuck me Ian” and that's why they'd opened the door. It was only as I was close to orgasm that I opened my eyes and discovered they were watching me. I heard Sharon say “Don't stop” I don't think I could have I was that close to cumming. But what sent me over the top was the sight of Ian naked, Sharon only wearing a pair of panties, stroking his large erect cock. I guessed they'd been watching me masturbate for several minutes but was so aroused I forgot to be embarrassed, laid with my legs spread, cunt exposed, masturbating with most of a 9 inch, black penis shaped, vibrator buzzing inside me. I couldn't stop and climaxed, watching as they entered the room and sat on the bed next to me. I was so shocked by what I'd just done, I just lay still, with my legs open, vibrator still buzzing inside me, until Sharon reached over, turned it off and with her hand on top of mine pulled it from my gaping hole. I dropped the vibrator on the bed, she was still holding my hand, guiding it to Ian's rampant cock. “Wouldn't you rather have that inside you?” she asked softly. I think I nodded. “I bet it's much bigger than John's and much harder too” she continued “Yes it is” I said dreamily, looking at it in my hand, so thick I couldn't close my fingers around its girth. She bent over, gave his balls a squeeze then ran her tongue up the shaft, over my fingers to his knob. She licked around his glans, before taking the end in her mouth and sucking him, whilst watching my reaction. I began wanking him, watching as she took more cock in her mouth, giving him a slurpy blow job. I licked my lips, probably a subconscious indication of my interest. It was enough for Sharon to stop sucking his cock “Umm, tastes nice too. Try it. Give his cock a suck” she said, offering it to me. I'd had a few drinks but not enough not to know what I was doing, I felt mellow and relaxed, excited by the what was happening. Still holding his cock I gave it a tentative lick then took it between my lips, just the tip, little more than a kiss. The realisation I had the cock of a guy I hardly knew in my mouth, both shocked and turned me on, the naughtiest and filthiest thing I'd ever done. With mounting arousal, I took an inch or two of his cock in my mouth, sucking him for maybe a minute or two, his hand stroking my hair, gently pushing my head down until his cock touched the back of my throat and I coughed and had to stop. I hadn't had much practice at cocksucking and had never deepthroated a guy, a skill I would like to master. Sitting up, Ian started to suck my nipples, still hard from when I'd been masturbating. I felt his hand on my thigh, gliding over my skin to my pussy, brushing through my pubes. I felt his fingers slip into my cunt. I reached for his cock again, Sharon was already wanking him, but it was so large, I was able to wrap my fingers around it too, the knob end still exposed for Sharon to suck. I could feel my juices running from my pussy, wetting my thighs. I began to move on Ian's probing fingers, three, then four of them, sliding in and out of my dripping hole. I didn't resist when he stopped sucking my nipples, rolled onto his back, his cock slipped from between Sharon's lips. I released it as he pulled me on top, straddling him. Sharon had slipped her panties off, I couldn't help noticing she was shaved, her smooth hairless cunt wet with her juices, nothing concealing her arousal, her pussy lips parted like petals, her pink hole slick, shining and gaping open. She laid beside us holding and wanking his prick as she guided it to my sex juice drenched cunt. I jumped when I felt her fingers, touch my clit, then relaxed, sighing with satisfaction as Ian's cock entered me. I lowered myself, unconcerned that Sharon's fingers were still touching my sex, no longer holding his cock but caressing my clit. I was overwhelmed by the sensation of Ian's thick cock, stretching my cunt, entering me more deeply than I'd ever previously experienced, as I took his length. She only moved her hand from between my legs when he'd fully penetrated me and we began to fuck. There was something about being watched which excited me, perhaps it was being fucked, while Sharon knelt next to us masturbating with one hand. Her other hand was holding his balls, touching my bum and pussy each time he fully penetrated me. Several times I felt one of her fingers slide inside me next to his cock. She kept fingering herself, then giving Ian her fingers to suck her juices off. It was just so filthy to see. She finally moved and crouched over his mouth, still masturbating while he licked and sucked her pussy while I rode his cock. For the first time in years I orgasmed more than once. I climaxed three times and he still hadn't cum. I could feel perspiration running down my body, dripping off my tits as I sat impaled on his throbbing cock. Sharon decided I'd had more than my fair share and half pushed, half dragged me off Ian's cock and mounted him. I was thirsty and needed to pee, by the time I got back Sharon was kneeling on the bed, being fucked from behind. I stood to one side, fascinated watching Ian's cock sliding smoothly in and out of Sharon's hole. My hand moved between my legs, almost of its own volition and, unselfconsciously, I began to masturbate. She turned her head, grinned at me before suggesting I kneel next to her and Ian could fuck us both. His control was amazing, neither my husband or the other two guys who I'd had sex with before had lasted more than a few minutes before cumming. Ian just kept on fucking us, giving me five or six deep stokes, then Sharon the same. Fucking one then the other, using his cock to fuck one of us, whilst finger fucking the other. Back and fore between us while we both fingered ourselves, frigging our clits and wanking. I heard Sharon cum at least twice I came again before I heard him mumble he was going to cum inside me. I felt his cock, pulse and throb as he ejaculated deep in my hole. He pulled out, penetrated Sharon and came inside her, before quickly pulling out, entering me giving me a second load. This time when he withdrew, Sharon had turned around, mouth open ready to take his cock. He came in her mouth and she gulped it down, then licked and sucked our sex juices and the last dribbles of spunk from his cock. Sharon had a huge super king size bed in her room and I had no hesitation joining them for the rest of the night. When I woke in the morning, I thought it might have been a dream until I reached out, found a hairy leg, a big pair of balls and as my fingers explored a stiffening cock. I looked the other side of him, Sharon sleeping, the quilt thrown back, her legs parted, revealing everything, reminding me how sexy her smoothly shaved pussy looked and that perhaps I'd shave mine too. I was still holding Ian's cock, feeling it growing harder. I looked at Ian, he was awake and rolled onto his side facing me. “I hope you're not going to let this go to waste” I whispered stroking his erection. His response was wordless, he got between my legs, grabbed my ankles, lifting and spreading my legs. He pulled me down the bed, raised my bum and slid his cock into my pussy. Once he was in and fucking me he put my legs over his shoulders, and fucked me with my legs folded back, squashing my tits, giving me amazingly deep penetration. It didn't take him long to get me squealing and begging to fucked hard, and give me his spunk, unsurprisingly waking Sharon who lay masturbating whilst watching us fucking. I fell asleep afterwards and Ian had gone when I awoke, a reminder of what I'd done, the spunk soak sheet under me and the sperm still oozing from my pussy. I went downstairs, found Sharon in the kitchen drinking tea. I made myself a mug and sat down looking a bit sheepish. “Well, well. There really is a Slut inside you” she grinned. I felt myself blush, began to deny it, then stopped and started to laugh. “I was a bit wasn't I. Didn't you mind Ian fucking me?” I wondered. “No. but tonight you can find one of your own to bring back” she said looking at me expectantly. “I can't do that, have sex with a guy I hardly know” I replied prudishly. It was her turn to laugh “Why not? You did last night and you sucked his cock. Don't try and say you didn't enjoy it” she reminded me. It was a strange feeling, despite still being embarrassed by what I'd done, I had to admit that I'd enjoyed it immensely. My show of reluctance was little more than a gesture and I took little persuading to go out again that evening. Besides Ian's beautiful big cock and the number of times he'd made me cum, there were other things I recalled from the previous night. I remembered how Sharon had touched my pussy, slipped a finger inside while Ian fucked me and stroked my clit, reluctantly admitting to myself that I'd enjoyed the sensation of another woman's soft fingers intimately touching me. I decided to say nothing about that, at least for the time being. The other thing was Sharon's smoothly shaved pussy. My husband had shaved me once and it had itched and become all splotchy and from then on I'd just kept my bush trimmed. I decided to ask her what the secret was and how she got her pussy so smooth, because I wanted my pussy to be like that, bare and my cunt completely visible to guys. That though had to wait for later when we were discussing our next night out and what to wear. I know this is relatively tame in comparison with some stories. All the same it still excited me, as the memories came flooding back and I have been masturbating while I wrote it. I hope some of you might have enjoyed it enough to have a wank too. This was just the beginning, little did I suspect, just how easily I would loose my inhibitions, to the extent that I'm not even sure how many guys have now fucked me. This has got a bit long and here is a good place to stop. I'll tell you more in Part two and you can judge for yourselves whether I'm turning into a Slut or, indeed if I'm already one. I'll wait and see how this is received before deciding if it is worthwhile continuing.
