I suppose the spark went out of my marriage about 5 years ago. In the final year arguments or long silences became more frequent, sex non-existent, not that I wanted sex, at least not with my husband. We separated in the summer last year after 15 years. Thirty seven years old, I was in no hurry to start another relationship but have always liked sex and the opportunity to pick up guys for one night stands, like I had before marrying, was certainly appealing. First though I couldn't ignore that I'd put on some weight, in the last year or two, most of it seeming to collect on my tummy and thighs. I had a trial membership at a Gym, found I enjoyed it and signed up after a couple of months. Once I decide to do something I have the willpower to see it through and managed to loose weight quite quickly, my tummy flatter, my thighs and bum firmer and toned. My tits are small, 32b but even they seemed more pert. At first I found sexual release from masturbation or using my vibrators and dildos until I became confident again in my body. In my fantasies, I was getting picked up by guys and having sex with them. I let my imagination run wild. My fantasies becoming more lurid, my pretend lovers getting me to perform naughtier and filthier acts. I used a vibrator in my bum while I masturbated or sucked a dildo while fucking myself with a vibe, pretending I was being fucked by two guys, things I'd imagined doing but never had, even in my younger, wilder days. By December and the party season I felt confident enough to go to bed with another man for the first time since splitting up. A few drinks to relax and I picked up a guy at a Christmas party and took him home with me. He was only 22 or 23 but what he lacked in technique he made up in stamina, fucking me five times before he left late the next morning. Having sex with a guy fifteen years younger than me was a great confidence boost. Being party season I went out again the following night, dressing in a short dress, some sexy lingerie with stockings and my highest heels and had no problem finding another young guy to take home to fuck me. Between the beginning of i December and the new year I was fucked by eight different guys, the youngest a student at the local university who was only 18 or 19, the eldest about my own age. I noticed men watching or turning to look at me with obvious interest. I found myself wondering how big their cocks were and what they'd like to do to me if they were fucking me. A guy who featured regularly in my fantasies before Christmas was Sam. Although he's about 8 years younger than me, we'd been friends almost since I joined the Gym. A drink after fitness training, the occasional coffee. I found him attractive, funny, easy to talk to, we'd flirted but no more. With my new found confidence in my body, I was determined to have him fuck me. I was looking forward to seeing him again and was disappointed when I didn't see him the next time I went to the Gym in January. He wasn't there the following time either. After I'd finished in the fitness suite, showered and changed I went to the bar, joining a group mainly to try and discover why Sam wasn't there. I sat with three guys he sometimes trained with and found that he was away on a course. For some reason after exercising I usually feel horny. That night was no different, I made it pretty clear to one of the guys I fancied, that I was up for it, took him home with me and had an amazing two hour sex session with him. He fucked me, making me orgasm several times, but holding back from cumming himself. I was well satisfied by the time he eventually pumped his spunk into my pussy. As we lay in bed afterwards I asked about Sam. Not very subtle talking to a guy who'd just fucked me, about another guy, but he didn't seem to mind. I found out that they'd talked about me, that Sam fancied me and wanted to fuck me which was excellent news. Perhaps even better he wasn't the only one who wanted to fuck me. He named half a dozen others, some I recognised when he described them. With Sam away for two months it seemed a shame to waste the opportunity to have sex with some fit virile guys. Over the next seven weeks, five of the six guys fucked me, most several times. The one who didn't fuck me, bottled out, claiming he couldn't fuck me because he was married, but not before I'd given him a blow job in his car and swallowed his spunk. I also had sex with three others who hit on me when they heard about my willingness to spread my legs and let any guy I fancied fuck me. I hardly spent a single night alone in my bed or two consecutive nights being fucked by the same guy, rapidly returning to my old, pre-marriage behaviour. It didn't really cross my mind, but I was earning the reputation for being a Slut. Most of them knew that I had the hots for Sam and I was looking forward to seeing him again and there were hints that at least one of them had told him they'd been fucking me. Some of them had made jokes about needing plenty of lube if Sam fucked me. Once when one of them was watching me masturbate with a 9 inch dildo I enquired if it was bigger than Sams prick. He said that he'd only seen it in the showers but if the size of it soft was anything to go by it was probably larger than the dildo when it was hard. I didn't know whether to believe him but was looking forward to finding out for myself if his cock was as large as they intimated. I heard he'd returned and would be at the Gym the following night. Hopefully my wait was over. I didn't think I’d have to much trouble getting him into my bed, certain that he'd been told that all his mates and some other guys had fucked me while he was away. Before going to the Gym I shaved my pussy, removing the pubes which until then I'd kept trimmed to a small triangle. Just to ensure he got the message that I wanted him, instead of my usual lycra shorts I wore some looser legged ones which I normally wear when I go jogging, putting them on without panties. My heart leapt when I came out of the changing room and saw him chatting to three of his friends, outside one of the fitness suites. I went over to join them. We chatted for a few minutes before going into the suite starting our warm up exercises. I moved where not just Sam but the others could see me. Sit ups, and squats etc but with my legs further apart than they should have been, deliberately exposing my cunt. With the exception of Sam they weren’t seeing anything they hadn't all seen before but it still made me wet and aroused, displaying myself to four guys all at once. It was mid week and quiet. The suite was booked for an hour and we had it to ourselves. I moved over to one of the padded exercise benches. I was excited being the centre of attention, wanted to let Sam see for certain what a horny slut I was. I told them I wanted to strip naked and masturbate if they made sure no one could get in. No one had ever come in while we'd been using the suite previously, but to be safe two of them stood against the door. With them all watching I pulled my vest over my head, tweaked my nipples, getting them hard before stepping out of my shorts. I stood in front of them naked, caressing my body, playing with my tits with one hand, the other resting on my mound, my fingers touching my clit hood, drawing it back uncovering my engorged clitoris. I stroked my clit, feeling my hard aroused button under my fingertips. Rubbing my sex I looked from one to the other, hoping they were getting hard, watching me play with myself. I wanted to masturbate in full view, completely expose my cunt to them and laid on the bench. I put my feet on the foot rests, spread my legs wide, exposing my smoothly shaven pussy. Reaching between my legs I ran a finger along my slit and into my hole. Feeling how wet my cunt was already I slipped a second finger in, pushing them both inside up to my knuckles. I'd never felt so excited or sexually aroused as I looked at them watching me as I gripped my pussy lips, stretching and holding my cunt open, wantonly displaying my soaking pink sex, before beginning to masturbate in front of them. It was as if as I'd shed the pounds I'd also shed my inhibitions. I'd performed sex acts on myself whilst being watched before but never by a group of guys. Slipping my fingers in and out of my hole, pressing against my hand against my clitty, I became more aroused and excited by what I was doing. I opened my legs wider, masturbating openly, without embarrassment for several minutes but wishing I had a vibrator or dildo to bring myself to orgasm. I looked around for a substitute, amongst the equipment, to use to fuck myself. Behind Sam I could see a shelf where skipping ropes were stored. The ropes weren't of interest but the plastic dildo shaped handles would be perfect in my pussy. I asked him to fetch one for me. He fetched two for me to choose. I selected one with about 8 inch handles made of a dimpled plastic material which I was certain would feel wonderful in my pussy. He went to hand it to me but I suggested he should fuck me with it while I concentrated on frigging my clitoris. I sat up a bit, stroking my clit softly, watching as as Sam pushed one of the handles into my cunt. He began to fuck me with it, sliding all of it into me, pushing it deeper with his fingers, until it disappeared inside me, then pulling it out with the rope. The dimples felt nice, but the handle wasn't really thick enough to stretch my hole and I told him to push the other handle into my cunt too, and use them both to fuck me. I moved my hands between my legs to help him insert them into my hole, by pulling my cunt wide open. I was unable to suppress a moan of pleasure as he twisted and rotated them, sliding them both into my pussy, while I pushed against them eager to feel them both inside me. My behaviour had become filthier and dirtier than anything I’d imagined, even in my wildest fantasies and I was loving every moment. Gripping both handles, Sam began fucking me with them, driving them deep into my cunt, holding one in each hand, separating them stretching my cunt open, as he withdrew them, while I frantically frigged my clitoris. I was getting closer and closer to climax, encouraging Sam to ram them in and out faster and harder. I groaned I was cumming, frigged my clit furiously with one hand, clamped the other over Sams forcing the handles deep into my cunt, holding them there, when I orgasmed. I felt him slipping them from my pussy and dropping them on the floor. I lay eyes closed, getting my breath back before reaching for him. I pulled him closer and told him that I wanted him to take me to his flat and fuck me. Even now I can't explain why I didn't want him to fuck me in front of his mates. After all they'd just spent the last 15 or 20 minutes watching me masturbate and had all fucked me at one time or another. It was probably a combination of things. Maybe partly because being watched having sex was something I'd never done and subconsciously blocked it. It may have been because I knew they'd all end up fucking me, in fact I think I wanted them too. Possibly because I still had enough self control left to realise that things would almost certainly get out of hand, they would forget guarding the door and we would get caught. I obviously wasn't quite as uninhibited as I'd thought. They looked disappointed as I stood up and dressed. Later I regretted not staying and letting them fuck me but made it up to them and several other guys who they told what I'd done, the following weekend. I grabbed hold of Sam by the arm, only stopping to collect my stuff from the changing room. Fifteen minutes later I was naked in Sam's flat, on my knees in front of him, feeling his cock through his shorts, about to peel them down and find out just how big his cock was. It felt very thick as my fingers traced the outline, feeling it stiffen as I rubbed it. My pussy drooled in anticipation, my sex juices running down my legs. I couldn't wait any longer, gripped the waist band, holding my breath as I eased the material over his cock. I wasn't disappointed when it popped out, almost slapping my face as it stood erect, inches from my mouth. The only surprise was that like me he was smoothly shaven which I rather liked and it seemed to make his cock look even larger. OMFG it was absolutely beautiful. The other guys might have exaggerated a bit, but not much. It had to be close to 9 inches long, with a thickness to match. I wrapped my fingers around it, unable to fully encircle his girth. I pulled the foreskin back, exposing the bulbous glans, stroking his shaft, squeezing some precum from the tip. With my other hand I fondled his heavy balls, squeezing them gently while slowly wanking his cock, while he pushed his shorts down his legs and kicked them away. I looked up at him, wondering whether to suck or fuck. I decided to savour the moment, take my time, hoping to intensify my pleasure and arousal. I licked my lips. “I want to suck it before you fuck me” I whispered. He sat on the edge of the sofa, leant back, his cock standing proudly erect. I shuffled closer, pushing his legs apart. I lowered my head to lick, then suck his balls. Licked up his rampant shaft, tasted the pre cum seeping from the tip, before rubbing it against my face, smearing the clear liquid on my skin. I felt his hand on my head, pressing down, heard him telling me to tongue his arse hole. I'd never rimmed a guys arse before but for Sam I was more than willing. He slid forward, raised his legs, and spread his buttocks. I ran my tongue back down his cock then from his balls to his anus. I licked along his bum crack then pressed the tip of my tongue against his arse hole. I licked back and fore between his anus and balls, whilst wanking his beautiful cock. “Wet your fingers in cunt juice and stick one in my arse” he grunted. I did as he wanted, dipping my fingers into my dripping pussy, coating them with my cunt juices. He held his cheeks apart, while I pushed one of my slippery fingers up his arse, then a second and began to push them in and out. I could feel his cock twitch in my hand each time I pushed my fingers in and hoped he wasn't going to cum. He didn't cum but his cock seemed to grow harder. “Take them out and use your tongue” he instructed after 2 or 3 minutes. I slowly pulled my fingers out, he held his arse open. I licked around his open anus, then a little hesitantly poked my tongue in, probing just inside his arse hole, then as deep as I could, wiggling my tongue towards his rectum when I realised that all I could taste was my own pussy juices. I must have been doing it right, his cock throbbing in my hand each time I poked my tongue as far as I could in his arse. I was enjoying being such a dirty slut, but to increase my own pleasure I moved my hand from his cock to my pussy, fingering myself as I rimmed his arse. He moved one of his hands from holding his cheeks apart to his cock and started to wank. I continued probing his shit hole with my tongue for another minute or two, getting increasingly desperate to be fucked. He didn't stop me when I surfaced from between his legs, kissed and sucked his balls, licked up his shaft to his knob end. Holding his cock steady, I took the tip between my lips and sucked his cock into my mouth. I lowered my head, taking more of his man meat in my mouth until it touched my throat. I wasn't known as the best cocksucker on campus for nothing when I was at Uni and though it was a while since I'd last done it hadn't forgotten how to deepthroat cock. Sam's was certainly the largest I’d attempted but I was determined to succeed. I swallowed, felt his cock enter my throat, suppressing the gag reflex, I lowered my head further, sucking and swallowing, his cock slowly sliding down my throat. I felt elated when my nose touched his smooth pubis and I'd taken the full length of his long thick cock in my mouth. I began to deepthroat him, lifting my head up, sucking his cock until just his knob was in my mouth, then slowly sinking down swallowing his length again 5 or 6 times before, releasing his prick from my mouth. I licked, kissed and nibbled my way up his body, teasing his nipples, kissing him on the mouth, while I climbed on top, straddling him, holding his erection and guiding it between my legs until it was touching my pussy. I sat up a bit. Looking between my legs, holding my labia, I pulled my cunt open, then sank lower, watching with delight as his prick penetrated my cock hungry cunt. Inch after inch slid into my hole, stretching me open, my cunt tight around his girth, until his cock was buried deep inside my appreciative pussy. With my hands on his shoulders I began to ride him, bouncing up and down on his shaft, enjoying the pleasurable sensation of having my pussy stretched and filled by his large cock. Each time he fully penetrated me I took the opportunity of grinding my clitoris against him. As I became more aroused, I began frigging my clit, crouching over him as he thrust his hot, throbbing cock into my sodden hole. It wasn’t long before I felt the first flutters of an imminent orgasm. The warmth radiating out from my cunt, my body and tits flushed pink, my nipples poking out hard. I rode him harder, the tingling sensation building, my cunt muscles starting to spasm. I moaned that I was cumming, begging him to cum inside me as I climaxed. He rammed his cock up me, held it inside while I shuddered, moaning and gasping loudly as I orgasmed. I was still in mid orgasm when he put his hands on my bum, stood up and with his cock still inside me. I put my arms around his neck while he carried me through to his bedroom. He lifted me off his cock, lowered me on to the bed, turned me over, lifted me onto my knees. Spreading my legs he entered me from behind and continued fucking me doggy. He fucked me to climax three more times. The last time I had a multiple orgasm, cumming in waves when I felt his cock pulsating inside me, as he pumped my cunt full of his spunk. It was a long time since I'd cum like that or felt so sexually sated. The evening was still young, we had a shower, a couple of drinks then back to bed. I sucked his cock, getting him hard before we fucked again. He joked afterwards that his mates had been right when they said I was an insatiable slut. Later I told him I wanted to measure his cock which of course meant getting him hard again. He didn't have a tape measure, but found a 12 inch rule. I sucked and wanked his cock until he was rock hard then measured him. 8 ¾ inches, less than it looked. I sucked him again trying to get him to 9 inches but didn't quite manage, not that I'm complaining. Once I'd measured him, he opened the bedside cupboard and took out a tube of lube. I had my doubts that I could take his cock in my arse, but after a little persuasion and copious amounts of lubrication, I took his cock in my bum and he arse fucked me. What happened the following weekend with his mates and especially the holiday we took when I didn't know where we were going until we got there and all he told me was that I wouldn't need many, if any clothes, will have to wait for another day if you're interested.
