I can still barely believe what I’ve been up to the last few months, after overhearing a conversation on the train. What started as a dare and a bit of a laugh with Lisa my best friend has progressed to the point where I can't and don't want to stop. The story really starts several years ago when we bought our detached house on the very edge of town, fields behind, very private and secluded. The garden was private enough to do the gardening or sunbathe nude, which I often did in the summer or in the conservatory if it was sunny but cool. We were concerned when the land behind was designated for future housing, but nothing happened until a couple of years ago when permission was given for houses to be built. We did our nimby bit, objecting that it would invade our privacy, not that it made any difference the houses were built and by this spring completed and occupied. As it happened only one house overlooked the garden, but that was enough to end my nude sunbathing after almost twenty years. I'm forty five and still have a fairly good figure, slim with long legs, I think my 40dd tits are to big, but thankfully they are still quite firm and don't sag. It must have been mid June, Lisa had called round, we were sat in the garden, wearing bikinis and I was bemoaning the houses behind and the lack of privacy. She didn't say anything immediately, seeming to be studying the house behind, before saying it looked empty, the owners probably at work. I looked, it did look deserted, Lisa had a wicked grin on her face, reaching behind her back undoing her top, holding it in place with her hands over her boobs. “I dare you to take your top off” dropping hers on the ground. I looked at the house again. “Go on. What's it matter if there is someone watching, give them a cheap thrill” with a nervous giggle I took my top off and it joined Lisa's on the ground. We spent a couple of hours sunbathing topless, seeing nor hearing a soul. Having apparently got away without being seen, over the next two or three weeks on the occasions the weather was warm enough, I went topless, enjoying the feeling of freedom and the sun on my naked tits. I normally only work mornings so looked forward to my afternoons in the garden. The weather hadn't been great, but sunny enough for my legs and top to be lightly tanned, noticeably paler where my bikini pants had covered, something I hate. It was a glorious day, I got home and showered, taking the opportunity to shave my pussy which was getting stubbly. I put on my bikini pants, checked the house behind from the kitchen window, deciding it looked empty, before heading down to the bottom of the garden. A nice sunny south facing spot behind the shed, about twenty feet from the shade cast by some trees and 6 foot fence dividing the garden from a little used footpath and the house behind. I checked the gate in the fence was bolted then laid on my lounger. From there I could only see one upstairs window, a bedroom which I didn't think was used. I'd never seen a light on, the curtains usually closed. I'd been going topless without being seen and decided it was safe to go the whole way and after one final check slipped my bikini pants off and lay back naked. I lay with the warm sun, bathing my naked body, rubbing sun lotion on paying particular attention to my tits, especially my nipples, feeling them stiffen under my touch. I poured lotion on my hand, spreading it over my stomach, my smoothly shaven mons and finally between my legs, massaging it over my pussy. My pussy felt quite wet, the lips parted, my button hard under my fingers as I slipped them in my slippery hole. I was tempted to continue and have a quick play, having often secretly masturbated in the garden in the past, but lost my nerve. I lay back again, legs parted, letting the sun tan between my legs. So confident was I that no one was looking, I even went up to the house naked to fetch a drink. Walking back I glanced at the house behind, noticing the bedroom curtains move, the windows slightly open. I couldn't remember if the windows had been open earlier, but decided they must have been, the slight breeze blowing the curtains. I settled back for another hour or so until it started clouding over. The next couple of days I was able to get out and again sunbathed nude, something I didn't tell my husband. Then it was the weekend, people in the house behind. The following Monday and Tuesday were wet and overcast. The Wednesday started warm but cloudy but by the time I was travelling home on the train at lunch time it was hot and sunny and I was looking forward to spending the afternoon in the garden. The train was fairly quiet, a dozen or so people in the carriage. I sat in a window seat, behind me a couple of young lads. The seats were those back to back sort and they sat in the seats right behind me, I don't think they even noticed I was there. Immediately they were on their phones, texting, chatting, one with the most irritating ring tone. Though the weren't talking loudly I could hear their side of the conversations which sounded pretty dull. Dull that is until just before our station. The annoying phone rang and he answered, more uninteresting chat. He said something about the weather, then “Yeh. I bet she'll be out today” silence while he listened. “She's got an awesome pair of tits and last week she stripped off completely” I realised they could be talking about me as he continued. “Honest mate. The lot, laid their, rubbing stuff on her tits. Her cunts shaved you can see everything. She even rubbed stuff on it, I thought she was going to have a wank but she stopped” I was virtually certain now, they'd been watching me. The one sided conversation continued, “I dunno. She's about thirty five. Fit though. Looks a right dirty slut. I'd fuck her” a few seconds silence, ”You're not wrong, definitely a MILF. Come round and see for yourself” I know what a MILF is and felt myself blush slightly at the description. I was also, rather pleased at his estimate of my age, flattered that they found me attractive and desirable. Though a little shocked they'd been spying on me and wanted to fuck me, I also felt rather excited by it, particularly as one of my fantasies when I used to play with myself in the garden was that I was being watched. The nearest I'd got was masturbating in front of my husband a few years ago on the beach, but that didn't really count. He finished his call just as the train pulled into the station and they both stood up, young guys as I'd thought, 20 or 21. I suddenly panicked, they might recognise me and looked out the window as they passed. They glanced at me, no indication they knew who I was, though I imagine in my smart suit, my hair up and wearing glasses, I looked different, after all they'd only ever seen me naked or near naked. I let them get off, then followed about a 100 yards behind, thinking about what they’d said, deciding it was unlikely they were describing someone else. They turned off the main road towards the new houses, then when I crossed I saw them, walking up the drive of the house behind mine. There was no doubt who they wanted to watch and fuck. Me!!!! I hurried home and went up to my bedroom and undressed. My panties were soaked with the juices leaking from my pussy. I showered thinking about what I’d overheard, excited by the things he'd said. I really wanted to go outside where they could see me. I started rubbing between my legs, eyes closed, imagining I was in the garden, getting more and more aroused. I wondered if they wanked, thinking about me, and how big their cocks were. I frigged until I came, but was no nearer deciding what to do. I went through to the bedroom and put on a thong. I'd been home 45 minutes, if I didn't go out soon they might give up. I went into the back bedroom, the curtains were closed. Taking hold of them, I opened them and stood, my tits on view, pretending to look at the garden, but keeping an eye on the bedroom behind. I stood for several minutes, I thought I saw the curtains move, but couldn't be sure. I went downstairs feeling a bit disappointed and fetched a cold drink, daring myself to go outside and do what I'd fantasised. I looked out the window towards the house. I immediately noticed that the bedroom curtains had been opened 2 or 3 feet and was certain I could see a hand holding one side, and a head in shadow. I felt a frisson of excitement, they were definitely watching. The moment of truth, I couldn't put it off any longer, I put on a pair of sunglasses so I could look without them knowing. I turned the handle on the door, opening it an inch or two, then stopped. Half of me was saying don't do it, don't be such an idiot. They other half wanted to be out there in the garden naked. I pulled the door open, stepped out and strolled down the garden, stopping bending to look at something, my bum towards them. Standing and stretching, sticking my tits out, feeling them jiggle as I walked down the garden to the spot behind the shed. I was trying to look nonchalant, but I was shaking with nerves, almost turning and going back inside. I reached the lounger, had a look around, glancing at the bedroom, noticing the curtain twitch. Before I changed my mind, I hooked my fingers in the sides of my thong and pulled it down my legs, bending to pick it up before laying back on the lounger. Having gone this far there was no going back, it was just a case of how far I was prepared to go before loosing my nerve. He'd mentioned watching me put sun lotion on so that seemed a good place to start. I tipped the bottle up and poured some on my tits, smiling to myself, thinking it looked like spunk running down the curve of my breasts, dripping off my nipples. With that dirty thought in mind, I massaged the lotion in to my tits, taking my time, stroking my erect nipples, before pouring more on my tummy, moving my hand lower until I was touching my shaved mound. I'd got to the real decision point, I hadn't yet done anything they hadn't seen before. Time to choose. Fun or run time. I chose fun, tipping the bottle and pouring lotion on my pussy, opening my legs, letting the cool liquid, trickle along my gash. As soon as I touched my clit I knew I wouldn't be able to stop. Gently rubbing it, feeling the hard little bud with my fingertips. I opened my legs wider, moved my hand, palm pressing my clitoris, slipping two fingers in my cunt. My other hand cupping a breast, teasing the hard nipple, I relaxed. I looked up at the window, my eyes hidden by the sunglasses. I could just make out, the shape of two guys standing back from the window watching, a third I suspect spying through a gap on one side of the curtains. I shivered with excitement and began to move my fingers in and out of my pussy, masturbating just as I’d imagined. He'd described me as being a “Dirty Slut” I hoped I was proving him right. I slipped all four fingers in my hole, twisting my wrist so I could rub my clitty as I fingered fucked myself. I'd never felt so sexually aroused, my fingers moving faster, flashing in and out of my cunt as I brought myself to an intense and satisfying orgasm. God I felt hot afterwards and not just from the sun!!! I'd done it, I could hardly believe it. I'd actually laid in my garden masturbating watched by at least three guys, I almost had to pinch myself to make sure I was awake. I lay back probably for another hour, legs open, occasionally reaching between my legs, touching my sex, dreamily rubbing my clitoris, slipping a finger inside then licking it. Just teasing them in to thinking I might have another play, eventually getting up and going inside. Perhaps the thing that surprised me most was that I didn't feel guilty or embarrassed, just an overwhelming desire to repeat what I'd done. Part of it was frustration, for the previous year, my husband had been working away frequently and sex had been getting, more unsatisfactory and infrequent. Even though he was home for a couple of weeks we'd only had sex once. I suppose at forty five, I felt that if I didn't do something wild and uninhibited, really let go, I never would. The following day I went out again, once again masturbating, then a little later fetching a vibrator to fuck myself, certain they'd be watching. As I climaxed, all I could think of was him telling his mate I was a MILF and that he would like to fuck me. Over the next few days I found I was thinking about having sex with them, masturbating at night while my husband slept beside me. It was an obsession and by the following week I was determined to have him or them and could think of little else. There was the problem of approaching them. I considered just waving them over, but couldn't be sure they'd see or respond. I wanted them to be in no doubt that I wanted fucking. I decided that the train might be the best bet. The Monday and Tuesday I didn't see them, the weather wasn't to good, no afternoons in the garden, though I did sit in the conservatory, naked and wanking, hoping they were watching. The Wednesday I realised a week had passed since I'd overheard them and wondered if for some reason they only went to the city that day. I thought I'd gamble they did and as it was a fine day wore a knee length wrap over dress, held closed by a button on one side, which would allow me to show some leg or more. There was no sign of them on the train in. I had difficulty concentrating on my work, wondering if they'd be on the train home and if I'd have the nerve to go ahead with what I'd half planned, worried they might not be on the train or the train might be busy and I wouldn't be able to be near them. I arrived at the station early, the trains to our town left every 20 minutes minutes, one was due to leave, earlier than the one I'd caught the previous week. I had a quick walk passed the carriages no sign of them and decide to wait. About ten minutes passed, I saw them at the end of the platform, my hunch had paid off. I went into the ladies and removed my bra and panties then back out, standing partly hidden by a advertising board where I could see them. The train pulled in, they stepped forward and I followed them into the almost empty carriage. I waited until they'd sat, then sat in the seat opposite, crossing my legs, deliberately letting the dress fall open. I could see them looking at my legs, as I opened and pretended to read my newspaper. Over the top of my paper I noticed them ogling me, then one whispering something, and looking back. I suspected they may have recognised me but weren't sure, I moved revealing more leg which kept their interest. I sat, the dress open almost to the top of my thigh for several minutes, until I heard one whisper again. I looked up, smiled at them, then crossed my legs the other way, lifting my leg higher than necessary, briefly flashing my pussy. I could tell from their expressions they'd seen. We were getting close to our station, I’d undone the button on the dress, the front loose but hidden by the paper. The train started slowing, a quick look, no one paying us any attention. I folded the paper, leant forward, feeling the dress fall open, “Yes I am the MILF you've been watching wanking in the garden. I don't suppose you recognise my face but I expect you recognise these” I flipped my dress open, sitting for several seconds with my tits and pussy uncovered before telling them, “The gate in the fence is unbolted, come over at two. I'll be waiting. You wanted to fuck me, now's your chance. Both of you and the other guy if he's about” I buttoned my dress just as we pulled into the station and got up. “See you at two” leaving them open mouthed. My heart was thumping, all the way home, thrilled that I’d had the courage to go through with it, nervous that they might not turn up. I had less than an hour to prepare. I showered, I'd shaved my pussy that morning so was nice and smooth. Went to the bedroom and smoothed body lotion on to my skin, put on a pair of stilettos, making my legs look longer and sleeker. I went downstairs to the conservatory, putting two or three things I might need on the table. Opening the doors to the garden I looked at the house behind. I thought they were watching from the bedroom and went outside. I wasn't that warm but I felt hot standing naked hoping they wouldn't be to long. I stretched my arms above my head, lifting my firm heavy tits than ran my hands down my sides before, lifting one tit then the other, licking and sucking my nipples. I was feeling so horny, that I couldn't help touch my pussy, parting my legs, fingering myself. My cunt was soaking, sex juices, wetting my thighs, as I pushed two fingers in my sex hole and stood by the door masturbating. A couple of minutes passed and at last the garden gate opened and the two lads from the train walked in. I called to them to bolt the gate and come up to the house. I'm not sure who was more nervous, them I think, as they looked at me, waiting to be told what to do. I stood back letting them pass into the conservatory. I didn't know their names, didn't ask or care, telling them to undress, while I closed the blinds. By the time I'd closed them they had undressed, standing stroking their nice hard cocks, looking at me. I pointed at the one I'd heard on the phone. “Come on then. You said you wanted to fuck me. Here I am. Fuck me or would you prefer me to suck your prick” I was beginning to think I'd made a big mistake, let my enthusiasm at the thought of getting some nice hard young cock get the better of me and overlooked the possibility they might not be able to perform. I was beginning to fear my plan was turning into a frustrating failure and that I should have tried to find some older, more experienced guys. I needed to get things started, take charge and hope they got over their reluctance. I pushed him back in a chair, took his cock in hand, bent over and licked his cock from balls to tip. I parted my legs exposing my wet gaping cunt, offering myself to the other lad. I stroked the cock in my hand and ran my tongue up it and around the glans, licking the pre cum as it leaked from the eye. At least he didn't cum, so deciding to make the best of it opened my mouth and started sucking his prick. I reached between my legs fingering my pussy, sucking him slowly in my mouth. I'd taken most of his length, when I felt his mate behind me, hands on my hips, then his cock, nudging my cunt. I moved my legs further apart, lifting myself as he slide his stiff prick inside my desperate hole. His initial nervousness had disappeared as he began to fuck me, holding my tits, pinching my hard nipples as he increased speed, ramming his prick in and out of my cock hungry cunt. I sucked the cock in my mouth greedily, my head bobbing up and down, sucking, nibbling, licking his hard young cock. My fingers rubbed my clitoris, frigging frantically, feeling a warm glow starting to spread from my cunt, an orgasm approaching. The lad I was sucking grabbed my head, thrusting his cock into my mouth, fucking my face as he squirted his spunk down my throat. He shot a second jet of tasty young spunk in my mouth which I gulped down, between gasps, as I neared climax. I raised my head, swallowing the last drops of spunk, revelling in the wonderful feeling of the other guy, slamming his cock up me, ramming his hard shaft in my hole, his balls slapping against my clit. I started to cum, a shuddering orgasm, as with two or three hard thrusts I felt his cock throbbing in my cunt, him grunting he was cumming, his thick creamy spunk filling my greedy pussy. After a slow start, I thought they'd performed quite well. I sat on the sofa, laid back, my bum off the cushions, spunk, running from my pussy, dripping on the floor and pulled one either side. I think you could safely say the ice had been broken, they couldn't keep their hands off me, particularly my 40dd's. Lifting one tit each, sucking and biting my nipples which drives me wild. I found their cocks, and began wanking them, hoping and expecting I'd be able to get them hard and ready to fuck me again fairly quickly. I wasn't disappointed, my earlier worries forgotten as I felt one stiffen then the other, With the attention my tits were receiving, one of them fingering my cunt and the feel of a pair of hard cocks, I was gagging for them to shag me. I felt in charge, that they were mine to do as I commanded. Still holding the guy's cock, sitting to my right, I straddled him, aiming his prick at my dripping hole and mounted him. His cock slide up me until I was impaled on his shaft, grinding my clit against his pubis. I began thrusting, his cock moving inside me, leaning on top of him, my erect sensitive nipples, brushing his chest. I turned to see what the other guy was doing, watching as he stroked his erection. Thick, hard and heavily veined, the knob end bulbous and leaking pre cum. I decided what I wanted. I've had anal sex on occasions, but had never been DP'd, though it had been a fantasy, wanking with a vibrator in my bum. I'd put a tube of lube on the table earlier and told him to lubricate his cock. He grinned in anticipation, massaging the slippery liquid on his prick. His grin got even wider when I told him to push the nozzle in my bum and squirt plenty of lube in my arse. I stopped riding, the cock in my cunt, laid flat, my tits squashed against his chest, and kept still. I asked the lad lubricating my bum if he'd arse fucked a woman before and wasn't surprised when he shook his head. I told him to spread my buttocks and use his fingers to loosen my bum hole. I felt first one then a second finger slide in my bum, I rocked on the cock in my pussy, pushing back on the fingers in my arse, slowly taking them, telling him to rotate them and work the lube in. After a minute or two I told him to stop, stretch my arse hole open with one finger and ease his cock up my arse. He was a bit over eager and tried to push it straight in, but I jerked forward with a scream. He got the message and we started again. I laid as flat as I could, to fully expose my arse hole, the guy underneath moving his cock in my cunt, while his mate prised my arse open and slowly eased the tip of his prick in my bum. I felt my anus stretching tight around his prick, as I he penetrated me. He pushed harder, an inch or so inside me, then he broke through the resistance, his hard thick cock sliding easily and smoothly up my arse until I'd taken his length. The sensation was heavenly, as they both began to fuck me. The incredible feeling of having both holes completely filled, their cocks touching inside me through my cunt walls as they steadily fucked my arse and pussy. Each time he thrust his cock up my arse, my clitoris tingled deliciously, as it rubbed against the body beneath me. My nipples felt so hard they hurt, a lovely warm flush spreading from my pussy, the muscles fluttering in my cunt, milking his throbbing cock as I had several mimi orgasms. The guy fucking my arse grunted each time he thrust his cock up me. They seemed to synchronise, their cocks endlessly sliding in and out of my holes, fucking me steadily for ten or fiftenn minutes. I was close to cumming again and guessed they weren't far off too. I felt them both ram their pricks in me hard, I had them both buried deep inside my holes, the guy arse fucking me gave an animal like groan as I felt his cock pulsating, pumping his spunk in several spasms up my arse. It felt superb when moments later I orgasmed just as I felt his mate ejaculating in my MILF cunt. I lay sandwiched between them for two or three minutes, their cocks softening inside me until the lad withdrew his prick from my arse and I lifted myself off the one in my pussy. I'd been enjoying my sexual adventure so much I'd lost track off time, realising with a jolt that there was less than a hour before my husband would be home. I told them to dress and leave, promising they could fuck me again. I noticed the cushion covers were soaked in spunk, juices and other stains, removed them, and wiped the spunk off the floor and put them on to wash, a quick tidy then upstairs for a shower and change into jeans and t-shirt. I only just finished minutes before my husband returned. A bit to close for comfort, but at least it was only going to be a short term problem as he was due away the following week. After a hesitant start I reckoned I'd got myself a couple of young lads who were compliant and more than willing to do what ever I asked to give me pleasure and sexual satisfaction. They and three or four of their friends kept me well satisfied until they returned to University after the summer holidays. Whilst I was sorry to see them go, by then another guy called Ben, who I'd met at a party they'd taken me to was seeing to my needs. Ben is black and absolutely beautiful, six feet tall, toned and muscular, completely shaved, including his cock and balls, and has smoothest skin which almost shines as if he's been oiled. Best of all he has the biggest, thickest, hardest cock I've ever seen. Almost nine inches and as thick as my wrist, I cum almost as soon as he penetrates me. The only difference is that I am now the compliant one. I've completely surrendered myself to him and become his white Slut, doing whatever he tells me to do, for him and anyone he chooses to give me to. That, I suppose is another story which I'll post if I get time and if anyone is interested.
