I already knew I turned heads, especially in my classes - I have a higher proportion of attractive, younger men signing up to my classes than my other female colleagues at one of the local universities - and I do dress to tease at times, depending on the audience. I married young (18) and gave birth to our first son (we have two) at 19 - my husband is 21 years older than myself, which never presented a problem sexually until about three years ago, but we compensated with toys, films etc. and I never felt the need to stray, although I can be an outrageous tease sometimes - it turns me on. I also run my own classes, sometimes at home, and this was where I first noticed I was turning heads, or rather one particular head, far closer to home. Just over a year ago, on a glorious summer day, I was leading a low-impact class in our garden for a few of our older neighbours; I'd come straight from one of my university classes and was wearing a tight fitting pair of black shorts and black sports bra top, with what can be best described as a matching pink bikini thong over the top of my shorts. (My class had been for some of the more attractive boys in my classes, and I liked to give them a good view of my backside to ponder on in the showers after class!) Anyway, not having time to change I just went home and started the class. My eldest son (at this time 18) was in the garden when I rushed out of the house to prepare for the arrival of my older ladies class, who were due in just a few minutes; there he was laid out on one of the sun loungers playing with his 'phone. 'Sorry, son; my class starts soon so you'll have to go in.' I said, although seeing him there in just his shorts, I did think about letting him stay - it may stop my class from dwindling over the winter months if the ladies knew they could get an eyeful of his muscular frame every lesson! I threw my kit bag onto the floor, and my son looked up, his eyes widening as he saw me in my outfit. 'Wow, Mum!' he said, a grin spreading on his face, 'Please make sure you don't look like that when my friends come over later to pick me up - they'll never want to leave!' I laughed, blushing slightly, but flattered all the same. 'Look, just make yourself scarce you cheeky sod!' I said, grinning back. I bent over the kit bag and started to get the equipment for the lesson out and, a minute or so later, heard my son walk past me into the house. A few hours later, my sons friends arrived to pick him up - they were all going away for the weekend to a music festival - along with my son's extremely gorgeous girlfriend, Jenny. 'Hi Mrs Edwards!' she proclaimed as she walked through the door. I have to admit, she's likeable enough, but there was just something about her I didn't like, although I couldn't put my finger on it at the time. Maybe the way she always seemed to give me a knowing, condescending smile. Maybe because of her young, pert, 18 year old body, dressed to flaunt in tight t-shirt, ripped slightly to show her impressive cleavage and the top of her black, lacy bra, and short enough to show her taught tummy just above a pair of tight denim hot-pants, leading down to black tights and Doctor Martin boots. My husband could hardly keep his eyes off her - he could be pathetic at times. 'I'll just go and get him - make yourself at home, you lot.' I said, and went upstairs to let James know that his friends were here. 'Sorry, Mrs Edwards,' said Carl, James' best friend, 'We need to make tracks - we've got to pick all of our supplies up, yet.' 'Beer, you mean...' I said grinning, already climbing the stairs. I got to James' room and tapped on the door, which swung open slightly at my knock - 'James, your friends are here - they say you need to leave sharpish...' 'Erm...okay....just a minute, Mum....' he stuttered. I could hear fumbling and his chair falling over, then one of his desk drawers slammed shut. I couldn't help but peek and saw James struggling to pull his shorts up, one hand stuffing his semi-erect member past the waist band of his shorts. I stepped back so he wouldn't see me and a second or so later, his door opened and he walked out, looking quite flushed. 'Oops' I thought, 'I've just interrupted my son relieving himself!' I laughed inwardly, and then thought 'Jenny mustn't be giving him any - poor thing...' 'C'mon, J!' called Carl. 'Gotta go, Mum' he pecked me on the cheek, 'See you in a few days!' 'Call me!' I shouted after him, 'Let us know you're okay...' There was no reply as the herd stomped, laughing and giggling, out of the house. His bedroom door was still ajar, and I could hear the whir of his computer - I decided to switch it off rather than leave it running all weekend. I walked into his room, and bent over to pick up his chair which was lying on its back. As I did so, I noticed something sticking out from the bottom drawer of his desk - they looked like a pair of lacy, black panties. 'Maybe she has been giving out after all...' I said out loud as I sat in the chair and turned the monitor on for the PC. I gasped audibly as I saw the image on the screen - it was me, bending over my kit bag in the garden earlier, giving a great view of my thong teased arse. 'Was he...,' I stammered, staring at the image,'While he...' the image formed in my head of my own son pleasuring himself while staring at my behind...I looked down at the panties and slowly opened the drawer - they were smeared in fresh cum and not only that, they were an old pair of my panties. I opened the drawer further - there was a small stack of my advertisement flyers in there, with a couple of them showing signs of having been wet at some point and then dried. The leaflets were just a glossy A4 sheet folded in half with a shot of me in a bikini in the centre-fold, advertising my 'Bikini Body' class for the previous year. I picked up one of the dried out leaflets and tried to open it - the pages were welded together. It looked like I'd been a sexual fantasy of his for some time. What was even more suprising was that I liked it - here was a drop dead gorgeous 18 year old who could have his pick of women my age; who was seeing a young girl who was also fabulous looking in every way, and he was choosing to cum while fantasising about me... As I've already said, I love the idea of teasing young men so that they fantasise about me, and the idea of my own son doing it - while shocking - was thrilling me! My attention returned to the PC - I saw there was a window open and I switched to it - I was presented with dozens of thumbnails, and they all looked like pictures of me. I opened one and started the slideshow - they were all of me, in various positions; on the beach in my bikini; doing my classes in the garden; doing some gardening in a pair of denim hotpants. I could tell they'd been taken with the digital SLR and telephoto lens James had begged us for for his 17th birthday, and the dates of the images confirmed it. I flicked back to Explorer and saw a folder named 'WOW' - I opened it and started the slideshow. These pictures had been taken from the boys' old tree-house at the bottom of the garden which, given the right equipment, gives you a view straight through the french doors which lead to the balcony outside of my bedroom. These were pictures of me in my underwear - panties and bra - he'd clearly not managed to catch me nude yet. In fact, he'd hardly been able to catch me at all from this vantage point; there were only a half-dozen or so pictures in this folder. By this point, I was beginning to get quite turned on by the idea of my son spying on me and jerking himself off to my pictures - I had to get out of the room. I put everything back the way I remembered it - I didn't want him knowing that I knew - switched the monitor off and left the room, my head spinning. That night me and my husband made love for the first time in a couple of months, but all through our love play I could not shake the images of James spying on me; getting turned on; spraying his cum onto pictures of me; even cumming on my underwear! I was so turned on by it all I nearly called out his name while my husband licked me to orgasm, imagining James was licking my pussy while he jerked his cock, spraying his cum onto the bed.... Immediately afterwards, I felt a small pang of shame at my fantasy, but that night and the night after I dreamt of James cumming on my pictures and once even cumming onto my bikini covered behind - both mornings I awoke with my pussy wet and needing to relieve myself with one of my toys. Now, most mothers would have avoided providing their voyeur son with photo ops but not me - I found the whole thing quite exciting. It was harmless, and my son would grow out of it - its not like we'd ever actually fuck, or anything... And besides, I wasn't getting the regular attention I was used to from my husband anymore, and it was nice to feel desired again. A few nights after James got back, I decided to play a little game. It was another gloriously hot day, and I made the point, repeatedly, that I would have to leave all of the windows open in my bedroom, including the french doors, if I was to have any hope of sleeping that night. My husband was out for a couple of hours arranging the annual summer bash at his golf club, to be held the following night, and during a lull in the evening I announced to the boys that I was going upstairs for a bath and to try on my new dress for tomorrow. Our house is quite secluded - we have no overlooking neighbours - and so I was as good as my word and left all of the windows open. Just as I was heading to the the en-suite, I saw James, camera in hand, furtively making his wasy to the tree house at the bottom of the garden. After a long bath (I wanted to give James plenty of opportunity to set up) I dressed in black panties and bra, suspenders and stockings and donned my shortest robe, slipping on a pair of high heels as I did so, and looked at myself in the tall mirror on the back of the door - my heels were showing off my legs nicely, and my robe gave a good shot of my cleavage as well as exposing the tops of my stockings. 'Yes,' I thought, 'I think he'll appreciate these snaps!' My pulse was picking up speed at the thought of what I was about to do.... I sauntered into the bedroom, where I knew I was now in full view of James' lens, and walked up to my dresser opposite the window and bent over, pretending to sort through some make up, my robe riding up over my rear slightly and exposing the stockings, suspenders and back of my panties to James' lens. I then bent over further, spreading my legs slightly, and rummaged through one of the bottom drawers for a minute or two giving him plenty of opportunity to photo my crotch, which began to tingle at the thought... After a minute or so, I straightened and, keeping my back to the window, slowly slid off the robe and then bent over, picking my dress off the bed and then slowly drawing it down over my body. The thought of James getting a hard on right at this moment was really beginning to turn me on... I admired myself in the mirror for a second or two and then put my right foot (the one closest to the window) onto the footboard at the bottom of the bed. I slowly ran my hand up my calf and along the back of my thigh, lifting my dress to reveal my stocking top, suspenders, and panties, and made a great show of 'adjusting' my suspender belt for a minute or two. I then stood in front of the french doors, this time facing forward with my feet about a foot apart, and slowly lifted the dress back over my head. I then had to 'adjust' the bra, grabbing handfuls of my breasts; pushing them together; pulling them apart, before removing the bra all together and letting my breasts free. I was so turned on by my stripshow at this point I was beginning to lose all inhibition - my nipples stood firm and my juices were flooding my panties. I kicked my shoes off and then, putting each foot on the footboard in turn, slowly drew my stockings down my legs, before dropping the suspender belt to the floor. As my grand finale, I hooked my thumbs into my panties and made out I was about to drop them, but just ran my thumbs around the top 'adjusting' them, before turning my back to the window once more, bending over, picking up and donning my robe. Just then my husband walked in to the bedroom. 'Hi, babe; trying on your new dress?' he asked. I turned, shut the curtains - I didn't want James seeing this - and dropped to my knees in front of my husband, pulling his cock free of his pants and straight into my mouth. I was aching with lust, although not for the man I was kneeling in front of... 'Fuck...' my husband gasped. I sucked him for a few minutes, getting him nice and hard, before leading him to the bed by his cock. I lay back on the bed, robe open and pulling my panties to one side - 'Fuck me...' I gasped. He shoved his 7 inch cock in me, and began thrusting quickly. It was feral, animal like sex - him thrusting his cock into me and me pushing back to meet his thrusts. I didn't look at his face once while we fucked; I just stared at his cock pumping in and out of me, fantasising it was James who had come in to fuck me instead, no longer able to control himself after my show... What was making this all the more exciting was that while I was sucking my husband I'd heard James go into his room and shut the door - he'd be in there right now jerking his hard cock, fantasising about me. My moans grew louder. 'Sshhh!' my husband hissed, 'I think James is in his room...' I shoved my fist into my mouth, muffling the cry of 'James!' as I came all over my husbands cock. Normally, quickies like this with my husband only last a few minutes before he's over the edge, especially with my soaking pussy pulsing 'round his shaft as I cum, but this time he pounded me for a good twenty minutes before he shot his load deep inside me. After this, I would wear the robe more around the house, trying to give James a glimpse of my thong or panties over breakfast when no-one else was around, or engineer scenarios for him to snaphot me. I knew it was wrong, but it was invigorating my otherwise flagging sex-life, and I was still of the opinion that it would go no further and was therefore harmless. As the early part of this year went on, my husband was having to spend more time away looking after parts of the company where they'd had to trim staff. This meant he was away for most of the working week pretty much every week, and my already spartan sex-life shrank to pleasuring myself, which is what led me to Literotica. I'd been searching online for taboo stories about mother/son relationships to spice up my self-pleasuring sessions when I stumbled on Literotica - the stories there kept me entertained for a while before I noticed the chat facility so, one hot afternoon a couple of months ago, I found myself registered and on under the 'HotMilf38' tag, chatting with a nice young man whose tag led me to think he may be willing for a bit of taboo role-play, which he was. Now, at the time, I hadn't admitted to anyone else about my fantasies, and so I just asked what role he'd like me to play, presuming from his tag that it would be his sister. 'My Mom' came his reply - my heart skipped a beat. Would I be able to admit, even anonymously, that I fantasised about fucking my own son? Well, I did admit it and our fantasy picked up pace, with me pleasuring myself with a Rampant Rabbit while I typed one-handed (and badly, I seem to recall) as our role-playing fantasy began to work to its conclusion. What's more, my son was out, and I had gravitated to his bedroom to lie on his bed while I did it. I ended up gushing my juices all over my son's bed as I came, and I as I was chatting to my naughty role-player, enjoying the pleasant afterglow, I heard my son come in downstairs - 'Fuck!' I nearly screamed. Panic set in and, despite my naughty chat partner trying to persuade me to fuck my son right there and then (you know who you are! :-) ), I signed off, threw a nightie on and quickly stripped the bed. This close call put a dampener on the games I'd been playing for the previous few months, but did not stop the lust I felt for James creeping into my mind all day and night - every time I fucked my husband now, I imagined it was James. Every class I did dressed to tease the young men, I imagined James there, his cock hardening in his shorts. Every time I pleasured myself, it was James who was in my mind.... This was becoming intolerable! My chat mate on Literotica had planted the seed that would end up taking the situation further - we both clearly fancied each other, he'd argued; why not just let nature takes it course? I formulated a plan. I decided to produce another pamphlet to advertise my business, but this time I'd use James for the photo shoot. We have a gym in the basement, with lots of equipment, floor to ceiling mirrors and, more importantly, no windows - the shoot would be held there. I'd wear the same bikini I had in the previous shoot - the one in the pamphlets he'd been spraying his cum onto for a year or more - and let him take control of the poses for the shots. This way, I thought, I could get him so turned on he'd ignore any inhibitions and things may progress to...well, we'd see. I mulled over this plan for a few months, constantly finding excuses to put it off, but in the end it was another Literotica encounter which pushed me to ask the question one night a few weeks ago. While furtively discussing my taboo fantasies with my chat mate (my husband was constantly in and out of the room...), I'd suggested my plan - he agreed it would be perfect and persuaded me to ask. My heart pounding, I agreed and walked from my bedroom to my son's room, where I knew he was. I knocked on the door and at the same time asked if it was okay to come in. "Erm - hold on a second - don't come in yet!" he shouted, I could hear him fumbling about. About thirty seconds later he opened the door enough to poke his head around - his face was quite flushed. I could hear the familiar whir of his computer and saw that the monitor was off. 'Perfect timing!' I thought. "Hi Mum...erm, what do you want?" he asked. I was wearing my short robe with black bra and panties - I accidentally let my gown open a little to expose more of my cleavage and the top of my bra. "I need to ask a favour - can I come in for a second?" I asked. I could see his eyes flitting to my cleavage - "Er...yeah...sure...." He pulled the door open and I walked in - he shut the door behind him as I sat on his bed, letting the gown ride up to show as much leg as possible - I crossed my legs giving him a quick glimpse of my crotch - and as I looked I could see his erection pushing against his shorts. 'My god,' I thought, 'His dick looks like it's about 10 inches long...' I caught myself staring, probably only for a second or two, but enough for James to notice - he picked up a jumper from the floor (as if tidying up) and held it in front of his obvious discomfort. "I'm needing a new pamphlet done for the end of season - just something to pick business up a bit over the winter, you know." I said, trying to sound as matter of fact as possible, "And I was wondering if you would do the photo shoot for me - it would be a great help, and would save us a fair bit of money hiring a photographer and everything..." I was starting to babble, "...I was thinking we could do it tomorrow in the gym in the basement while your brother is at school and your dad is away on business." 'Have I just said that out loud?' I thought, 'That last bit sounded like a direct invitation to fuck me!!!' A Fantasy Too Far... His face flushed a deep red and he nervously shifted his jumper. "Yeah....yeah, that'd be great!" A grin split his face from ear to ear. "That settles it," I said, my heart now trying to pound its way through my rib cage, "I'll see you in the gym after everyone's out." The following morning, after seeing off James' younger brother and my husband, who was now away for three days on business, I got ready. I donned the bikini which had been the object of his fantasies for so long and then, over the top, the baggiest jogging bottoms and top I could find, although the bottoms still hugged my bum in a pleasing way when I bent over. I let the zip down on the top to give a tantalising view of my cleavage. I was working out in the gym when James entered in a pair of khaki knee length shorts and a baggy t-shirt, long enough to cover his crotch when standing up. I could see the disapointment in his face when he saw what I was wearing. "I was thinking we could get a couple of shots of me standing by various bits of equipment, and then a few more of me working out - what do you think?" I said. "Yeah, whatever you say, Mum." his voice had that flat tone of a surprise spoiled. The plan was working perfectly. We went through a few boring shots of me standing by equipment and I let him do a few more shots of me exercising - he took plenty of time getting shots of my arse, even though it was covered by the jogging bottoms, and when they were done I was pleased to see from the front of his shorts that he was already getting the stirring of an erection. "Right," I said - my heart was pounding at this moment; this was the make or break of the plan: would I have the courage? Would he be interested? - "That's the boring stuff done, now for the fun stuff..." I looked him straight in the eye and unzipped my top, revealing the bikini top, and casually dropped it to the floor, his eyes widening appreciatively. I kicked my training shoes off, turned on my heel and pulled my jogging bottoms down, bending over to hook them over my feet - I caught my son's expression as I glanced at his image in the mirror; he was stood there, his mouth wide open, just gazing at my behind. I stood and turned around, not hiding the fact that I was now staring at his swelling cock beneath his shorts. "Now, I want you to tell me exactly what poses you would like to see me in,' I brought my gaze slowly up from his swelling cock to look him in the eye, 'What do you think would draw the most interest?" He spent the next twenty minutes or so snapping me in various positions, his excuses on why I needed to bend over, or stretch one of my legs on some equipment, so he could get a good view of my bum, crotch or cleavage becoming increasingly tenuous. As this shoot continued, I was becoming more aroused by the second, my bikini bottoms were getting damp from my juices and my nipples were trying to burst through my bikini top. I could also see James' appreciation of the situation - his cock was straining against his shorts, way below his t-shirt - 'It must be 10 inches long, at least' I thought, and I could see a damp patch of pre-cum soaking through where his prick was rubbing against the cloth. Suddenly, James put the camera down and said, "Look, I've got to go to the bathroom - I'll be back in a minute." This was the moment.... "I can see by the state of your shorts why you need to go to the bathroom," I said, smiling. "Oh, god....sorry, Mum....I....er...." he stammered. "Don't apologise! It's my fault, really, wearing this bikini when I know you like to look at me in it." His face flushed a deeper red at this. "If you need to get rid of your discomfort so we can carry on with the shoot, just do it here - I'll turn around and won't watch, I promise!" "Oh, fuck....god, sorry....I..." he was shifting nervously on his feet. 'Damn!' I thought, 'I can't have misread this, can I?!?' I turned around slowly and bent over, placing my hands on the bench in front of me to steady myself, and arching my back slightly to accentuate the curves of my hips and ass. "Go on..." I said, looking at his reflection in the mirror, "I want you to...". "Jesus...." he gasped, eyes widening. He pulled at his shorts, his cock leaping out and up as the elastic passed the swollen mass of his prick, and as his shorts were slowly sliding down his lower legs he began to frantically jerk his cock - the end was shiny with pre-cum and the slapping noise of his motion was making me want to moan out loud. "Closer!" I gasped' "Come closer!" He waddled forward, but was still a good arms reach away. He couldn't take his eyes of my behind. I wanted his hands all over me! "Closer, please! I want you to grope me!" I implored. He kicked his shorts from his feet and walked over, letting go of his cock, and began to knead and grope my buttocks. "Carry on rubbing yourself," I said, "I want to feel you cum on my bum" "God....I can't believe this is happening..." he moaned, and began jerking his cock with his right hand while still feeling me with his left. I began rocking slowly back and forth, forcing his cock onto my bikini bottoms and into the crevice of my arse, squeezing his prick with my cheeks. His breathing was getting heavier. "Oh, god...." he moaned, "Fuck! I'm gonna cum..." his left hand grabbed me by the hip, pulling me up and closer. He forced the end of his cock between the cheeks of my arse so that the only thing between his cock and the hole in my behind was my bikini bottoms - this was so erotic! He was about to spray his cum between my arse-hole and my pussy!!! Looking at him through the mirror I could see him biting his lower lip, staring at my behind, as his hips began to buck - dry humping me, his rock hard prick trying to force my bikini bottoms and itself into my arse - and his animal like grunts and the hot splashes running down the inside of my thighs told me he was cumming. "NNnnnnnnnngggghhh, yeah....." he groaned. "Yeah, James - cum all over me! Cum all over your Mummy!" I moaned. I couldn't believe this was finally happening! When he finally stopped rubbing his cock, he staggered back and slumped onto one of the benches, his eyes closed, breathing heavily. He still had his cock in his hand, cum oozing over his fingers as his erection began to falter. I walked up to him and kissed him, fully on the mouth, poking his lips with my tongue. His mouth opened, and we kissed passionately, our tongues wrapping around each other; our hands were restless, not stopping on one part of the others body for more than a moment. When we stopped kissing, he looked at me and said, "I...I don't know what to say..." "Don't say anything," I replied, "I've wanted you to do that for some time." I explained to him how I knew he was fantasising about me; how it turned me on; how I teased him knowing he was watching. "Now," I said, "Are we going to continue with the shoot?" "Er, yeah...sure." he said, moving to pick up his shorts. "You won't be needing those" I winked, "In fact, you can lose your t-shirt as well." A grin spread across his face, and he pulled his t-shirt up over his head revealing his taught, athletic body. We continued with the shoot, this time I took the lead striking poses I'd seen in James' 'secret' porn stash; pulling my bikini bottoms to one side and fingering my pussy, then licking my own juices off my fingers. Within minutes his cock was fully erect again, its impressive length standing proud in front of him. He put the camera down and started to jerk his cock again. "No you don't...," I said, getting up off the bench I was posing on and kneeling in front of him, "I've got a better use for that...." I put my hands on his firm buttocks and looked him straight in the eye as I ran my tongue up his scrotum, along his shaft, around the head of his penis, and sucked the end of his cock into my mouth. "Oh, Jesus Christ, Mum! That's amazing..." he moaned. I could feel by how I had to stretch my mouth that his cock was much thicker than his dad's - my pussy was aching for him to fuck me! Slowly at first and then picking up speed, I began to bob up and down on his cock - I couldn't get his massive prick into my throat so I attended to the bottom of his long, thick shaft and his scrotum with my hands. His moaning was growing louder as his hands went into my hair, grabbing my head, and he began to gently thrust his cock in and out of my mouth - I grunted with each thrust as the end of his cock tried to work its way into my throat. After a couple of minutes I pulled away, got up and lay back on the bench, pulling my bikini bottoms off and spreading my legs - I needed relief. "Show me what you do to Jenny with your tongue." I said. He knelt between my legs, looking me straight in the eye, not saying a word as he kissed his way from my breasts, still encased in my bikinim top, to my inner thighs, working his way up and down each thigh but never touching my pussy - this tease was sending me closer to the edge! "Please!" I gasped after just a few minutes, "Please lick me!" He used his tongue and his fingers skillfulfy, licking me with an ever building rythm and teasing my hole with his fingers. Within minutes he'd brought me to a screaming orgasm, his name echoing around the gym - he was clearly experienced in this department! I lay there, panting, not wanting this to end but unbelievably still unsure about whether to allow it to go further. I looked up and saw James getting to his feet, his lower face soaked with my juices. "Oh, god....fuck me, James. Please - fuck me...." I gasped. "Fuck...." he sighed "I've dreamt about this for so long, I can't believe it's happening!" He pushed me further back on the bench and straddled it, staring at my dripping pussy. He grabbed his long, thick cock by the base and pushed it's head - gently - into my lips. He looked me in the eye as he pushed his dick further into me - I could feel myself stretching around it; it was much thicker than his dad's, and longer - on and on, up towards my womb. "My god...." I moaned, "Your cock's so fucking big!" Once he'd got his full length into me, I grabbed his hips - "Wait..." I said; I needed a couple of seconds to get used to his girth. I gently rocked back and forth, easing myself around his cock. His hands were groping my breasts through my bikini top, moving across my belly, my legs, my arse. "God, yes!" he moaned, "This is how I've fantasised about you...I've made myself cum so many times thinking about fucking you right here in the gym...fucking you while you wear that bikini...." "Fuck me..." I whispered, "Fuck me as hard as you've imagined youself doing...." He leant forward, grabbing the equipment above my head, and began pumping his cock in and out of me, almost withdrawing completely before pushing his whole length back into me. Slowly at first, but the rythm building, building.... God, it was amazing! I could feel his desire pouring out of him; in his wide eyed stare; the power of his thrusts; the steel of his cock. My hands were now all over him, feeling his taught, muscular stomach, his chest, arms, hips, bum. I pinched his nipples, hard. "God, yeah!" he moaned. The fordbidden nature of what we were doing, coupled with his huge cock and youthful exuberance sent another orgasm crashing through me - "Aaaaaah! Yyyeessss! James! Fuck me! Baby! Fuck me!" I screamed. As my orgasm subsided, he let go of the equipment and leant back, looping his arms under my legs and putting his hands under the small of my back. He stood, lifting my lower body up - he was now standing with his legs straddling the bench, the muscles of his arms, chest and neck straining as he quickly picked up his relentless rythm again, slamming his cock into me again and again and again and again, each thrust seemingly harder than the last. He was staring at my breasts as they bounced and jigged under the bikini top - he was fucking me so hard my breasts came loose, popping out of the cups - and grunting through gritted teeth "Fuck! Fuck! Fuck! Fuck!" in time with each hard, deep thrust. I was delirious with desire - I hadn't been fucked like this in years - I began shouting filth at my own son -"Stick your big fucking cock in me, James! Harder! Fuck me harder! Fuck your own mother, James! Fuck me! I'll let you fuck me in the arse, James! You can do whatever you like to me! God, yes - fuck me! You're going to make me fucking cum again!" I pulled my bikini top down and grabbed hold of my breasts - my nipples were on fire! I brought each nipple to my mouth in turn, sucking on it and licking my own breasts, all the while staring into my son's eyes. I was moaning, urging him on - "Cum in me, James! Fucking cum in me!" With a breast to my mouth in one hand, licking and sucking the erect nipple, I pinched one of his nipples with the other. "FUCK!" he shouted, "MUM!!!" The slap-slap-slap of his thrusts picked up pace. He threw his head back - "I'M CUMMING!!! MUM!!! I'M CUMMING!!!!!" He looked back at me, his eyes like saucers, the veins standing out on his neck and arms as he filled me with his cum. "Yes! Cum, James! Cum in me!" I moaned. His thrusting was frantic, hard, almost pushing me from the bench - I had to reach over my head and grab the equipment to stop me falling to the floor.
